Threat Analysis: Active C2 Discovery Using Protocol Emulation Part3 (ShadowPad)
(published: October 27, 2022)
ShadowPad is a custom, modular malware in use by multiple China-sponsored groups since 2015. VMware researchers analyzed the command-and-control (C2) protocol in recent ShadowPad samples. They uncovered decoding routines and protocol/port combinations such as HTTP/80, HTTP/443, TCP/443, UDP/53, and UDP/443. Active probing revealed 83 likely ShadowPad C2 servers (during September 2021 to September 2022). Additional samples communicating with this infrastructure included Spyder (used by APT41) and ReverseWindow (used by the LuoYu group).
Analyst Comment: Researchers can use reverse engineering and active probing to map malicious C2 infrastructure. At the same time, the ShadowPad malware changes the immediate values used in the packet encoding per variant, so finding new samples is crucial for this monitoring.

Raspberry Robin Worm Part of Larger Ecosystem Facilitating Pre-Ransomware Activity
(published: October 27, 2022)
The Raspberry Robin USB-drive-targeting worm is an increasingly popular infection and delivery method. Raspberry Robin works as a three-file infection: Raspberry Robin LNK file on an USB drive, Raspberry Robin DLL (aka Roshtyak) backdoor, and a heavily-obfuscated .NET DLL that writes LNKs to USB drives. Microsoft researchers analyzed several infection chains likely centered around threat group EvilCorp (aka DEV-0206/DEV-0243). Besides being the initial infection vector, Raspberry Robin was seen delivered by the Fauppod malware, which shares certain code similarities both with Raspberry Robin and with EvilCorp’s Dridex malware. Fauppod/Raspberry Robin infections were followed by additional malware (Bumblebee, Cobalt Strike, IcedID, TrueBot), and eventually led to a ransomware infection (LockBit, Clop).
Analyst Comment: Organizations are advised against enabling Autorun of removable media on Windows by default, as it allows automated activation of an inserted, Raspberry Robin-infected USB drive. Apply best practices related to credential hygiene, network segmentation, and attack surface reduction.

2022-11-01 10:00:00 | Choosing a DAST solution: What to pay attention to? (lien direct) | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. The majority of today's web applications contain dangerous vulnerabilities. To analyze their security, one cannot do without a dynamic scanner. DAST (Dynamic Application Security Testing) tools allow you to detect and evaluate security problems quickly. Let me tell you what to look for when choosing such a tool. According to various studies, 70% of vulnerabilities have to do with errors in the code. Using vulnerabilities in your web application code, hackers can distribute malware, launch cryptojacking attacks, employ phishing and redirect users to malicious sites, hack a phone remotely, or steal personal data using social engineering techniques. Yes, sure, it is impossible to create perfectly secure software, but it is quite possible to reduce the number of vulnerabilities and increase the level of product security. To do this, you can rely on DevSecOps - a process that links development and security and where software is checked and tested for vulnerabilities at every stage of its creation. The DevSecOps process is very voluminous; it may include numerous information security tools. In this article, I want to talk about DAST and how to choose the right scanner for dynamic application analysis. Together we will figure out what tool characteristics and parameters you need to pay attention to and what product types are currently available on the market. What is DAST, and how does it work? Dynamic application security testing is one of the secure development practices where an automated analysis of a deployed and functioning application is carried out. The dynamic scanner checks all access points via HTTP, simulates external attacks using common vulnerabilities, and simulates various user actions. The tool determines which APIs the service has, sends verification requests, uses, where possible, incorrect data (quotes, delimiters, special characters, and more). The dynamic scanner sends and analyzes a large number of requests. The analysis of the sent request and the received response, as well as their comparison with a regular request, allows you to find different security problems. Most scanners have similar functions and modus operandi. Their main components are a crawler and an analyzer. The crawler traverses every link on every page it can reach, examining the contents of files, pressing buttons, and going through a dictionary of possible page names. This process allows you to estimate the size of the attack surface and possible attack vectors taking into account the existing ways of interacting with the application. The analyzer checks the application directly. It can work in passive or active mode. In the first case, the analyzer studies only information that the crawler sends to it. In the second, the analyzer sends requests with incorrect data to the points found by the crawler and to other places that are not currently present on the pages but can be used in the application. It then infers the presence of a vulnerability based on the server's responses. What should you pay attention to when choosing a DAST tool?

IMAGINE accelerating security resilience at a fraction of the cost – an operating foundation at scale to change how we play the infinite game of cybersecurity and even shift the security cost to the bad guys.
Muhammed Ali was not the strongest and toughest boxer – he owned the middle of the ring, using his speed to play the infinite and shift the hard work to his adversaries – he was the greatest.
Elevating Security Resilience requires focused visibility to deliver the punches – the underlying foundation must be automated to keep up with scale at a fraction of the cost.
The popular mantra says, “every business is a digital business; you’re digital, or you’re dead.” This could not be truer in today’s world. While digital transformation has been an ongoing trend, Covid-19 accelerated that transformation beyond normal. Companies transformed their digital processes 20-25[1] times faster than before due to the onset of the pandemic. The changes included customer interactions, employee engagement, back-office processes, supply chain, and more. It’s a cliché to state that cyber becomes a core business risk as businesses get more digitally connected. Scan the SEC filings of any publicly listed company, and it’s amply clear that digital transformation unlocks massive growth but also expands the risk profile for most organizations. Cyber resilience is business resilience. The corollary holds equally true – cyber fragility impedes business growth.
 Figure 1: Digital transformation & cyber risk
The traditional approach to cybersecurity has focused on a tech-centric approach to security, evolving a technology acronym soup, continuously trying to find the smarter tool to speed up and scale security operations. This approach, somewhat successful at the lower levels of digital transformation, has become unmanageable and incredibly expensive for businesses. In spending time with board directors, management teams, CIOs, and CISOs, we’ve realized that there is a dire need to pause and reset the foundational thinking with an eye on more effective delivery that can scale at a manageable cost.
When an attacker targets an organization, they start by first conducting reconnaissance and understanding a company’s business model, profile, and strategy. Security needs to focus on the WHY - the business context. Why are they an interesting target, and what can they do to deter the attackers? This fusion of business context with security is critical to transforming security for the modern enterprise and helping executives answer key questions on business risk and resilience.
As Einstein aptly said, “we cannot solve our problems with the same thinking we used to create them.”
Sprucing up Security Operations
A recent ESG survey highlighted that 52% of security professionals consider security today more complex today than two years ago[2]. There are several drivers for this, including changing threat landscape, growing attack surface, higher volume and complexity of security alerts, growing adoption of public cloud services, keeping up with operational needs of SecOps technologies, and collecting and growing more data.
Elevating security necessitates a step back first to understand the goal.

Alert (AA22-294A) #StopRansomware: Daixin Team
(published: October 21, 2022)
Daixin Team is a double-extortion ransomware group that has been targeting US businesses, predominantly in the healthcare sector. Since June 2022, Daixin Team has been encrypting electronic health record services, diagnostics services, imaging services, and intranet services. The group has exfiltrated personal identifiable information and patient health information. Typical intrusion starts with initial access through virtual private network (VPN) servers gained by exploitation or valid credentials derived from prior phishing. They use SSH and RDP for lateral movement and target VMware ESXi systems with ransomware based on leaked Babuk Locker source code.
Analyst Comment: Network defenders should keep organization’s VPN servers up-to-date on security updates. Enable multifactor authentication (MFA) on your VPN server and other critical accounts (administrative, backup-related, and webmail). Restrict the use of RDP, SSH, Telnet, virtual desktop and similar services in your environment.

2022-10-25 08:00:00 | Quarterly Report: Incident Response Trends in Q3 2022 (lien direct) |  Ransomware and pre-ransomware engagements make up 40 percent of threats seen this quarterBy Caitlin Huey.For the first time since compiling these reports, Cisco Talos Incident Response saw an equal number of ransomware and pre-ransomware engagements, making up nearly 40 percent of threats this quarter. It can be difficult to determine what constitutes a pre-ransomware attack if ransomware never executes and encryption does not take place. However, Talos IR assesses that the combination of Cobalt Strike and credential-harvesting tools like Mimikatz, paired with enumeration and discovery techniques, indicates a high likelihood that ransomware is the final objective. This quarter featured a variety of publicly available tools and scripts hosted on GitHub repositories or other third-party websites to support operations across multiple stages of the attack lifecycle. This activity coincides with a general increase in the use of other dual-use tools, such as the legitimate red-teaming tool Brute Ratel and the recently discovered Manjusaka and Alchimist attack frameworks. .jpg) TargetingAttackers targeted the education sector the most of any vertical this quarter, closely followed by the financial services, government, and energy sectors, respectively.

2022-10-20 13:36:00 | Threat Hunting: Eight Tactics to Accelerating Threat Hunting (lien direct) | One of the more significant headaches in cyber security is the overuse of buzzwords and acronyms and the overlapping mutations of what they mean. Cyber threat Hunting has become one of those phrases, but it has gained clarity over the last few years as organizations strived to become more proactive. So what is threat hunting? Depending on who you ask, you may get somewhat different answers to the same question. Cyber threat hunting is a proactive approach to detecting suspicious activity from known or unknown, remediated, or unaddressed cyber threats within an organization’s networks. It involves finding malware such as viruses, Trojans, adware, spyware, ransomware, worms, bots, and botnets. The goal is for security analysts to find these threats before they cause damage to systems and data. It’s similar to how fire departments respond to fires; they go into buildings to ensure no additional problems before calling the firefighters. There is a vast collection of tools, skill sets, approaches, and processes to help identify advanced threats that could happen within the network. What is an effective hunting process for one organization may be a waste of time for another, depending on each company’s understanding of what threats they might face. Man-hours spent hunting are typically most beneficial for large organizations targeted by the cybercriminal community regularly, but that’s not to say that regular hunts for small/medium-sized enterprises can’t benefit from and identify threats by doing the same. Structured Threat Hunting The structured hunt is based on indicators of compromise (IOCs) and tactics, techniques, and procedures (TTP). IOCs provide information about potential adversaries, such as IP addresses, domain names, operating system versions, etc. TTPs describe how attackers operate and what tools they use. Combining IOCs and TTPs makes it possible to build a picture of the adversary. This approach allows us to detect threats earlier and prevent attacks. In addition, we can quickly identify the threat actors because each activity is described in detail. Unstructured Threat Hunting The concept of unstructured hunting is relatively new. It wasn’t until 2013 that we began seeing the emergence of unstructured hunters. Unstructured hunting is a method of finding malicious software (malware), such as viruses, Trojans, worms, etc., without knowing exactly what type of malware you are looking for. Instead, the hunter relies on behavioral analysis to find these threats. In short, unstructured hunting is investigative work where a cyber threat hunter observes behavior and looks for anomalies. For example, if someone sends out spam emails, a system administrator might notice unusual activity on his network and investigate further. If he finds something suspicious, he could take action immediately or wait a few days to see if the same email addresses start sending again. Traditional Threat Hunting The traditional definition of threat hunting can be defined as a focused and intensive human/machine-assisted process aimed to identify the possibility of something malicious happening within the network or likely about to happen; this is based on abnormal network behavior, artifacts, or identification via active threat research. A good example of this would be: A large bank has team members whose part of their job is to consume threat reports related to activity targeting their vertical and other companies that match their Enterprise profile. > A new threat report is published from an intel provider describing a new variant of malware that has been catastrophic at similar organizations. This report would ideally contain information around the process tree, registry key, etc., to help the cyber threat hunters not just hunt for detection of the associated IOCs but dig deeper to identify patterns that match the behavior of the malware across the network, like abnormal PowerShell executio | Spam Malware Tool Vulnerability Threat | ||

2022-10-20 13:01:02 | Announcing GUAC, a great pairing with SLSA (and SBOM)! (lien direct) | Posted by Brandon Lum, Mihai Maruseac, Isaac Hepworth, Google Open Source Security Team Supply chain security is at the fore of the industry's collective consciousness. We've recently seen a significant rise in software supply chain attacks, a Log4j vulnerability of catastrophic severity and breadth, and even an Executive Order on Cybersecurity. It is against this background that Google is seeking contributors to a new open source project called GUAC (pronounced like the dip). GUAC, or Graph for Understanding Artifact Composition, is in the early stages yet is poised to change how the industry understands software supply chains. GUAC addresses a need created by the burgeoning efforts across the ecosystem to generate software build, security, and dependency metadata. True to Google's mission to organize and make the world's information universally accessible and useful, GUAC is meant to democratize the availability of this security information by making it freely accessible and useful for every organization, not just those with enterprise-scale security and IT funding. Thanks to community collaboration in groups such as OpenSSF, SLSA, SPDX, CycloneDX, and others, organizations increasingly have ready access to: Software Bills of Materials (SBOMs) (with SPDX-SBOM-Generator, Syft, kubernetes bom tool) signed attestations about how software was built (e.g. SLSA with SLSA3 Github Actions Builder, Google Cloud Build) vulnerability databases that aggregate information across ecosystems and make vulnerabilities more discoverable and actionable (e.g. OSV.dev, Global Security Database (GSD)). These data are useful on their own, but it's difficult to combine and synthesize the information for a more comprehensive view. The documents are scattered across different databases and producers, are attached to different ecosystem entities, and cannot be easily aggregated to answer higher-level questions about an organization's software assets. To help address this issue we've teamed up with Kusari, Purdue University, and Citi to create GUAC, a free tool to bring together many different sources of software security metadata. We're excited to share the project's proof of concept, which lets you query a small dataset of software metadata including SLSA provenance, SBOMs, and OpenSSF Scorecards. What is GUAC Graph for Understanding Artifact Composition (GUAC) aggregates software security metadata into a high fidelity graph database-normalizing entity identities and mapping standard relationships between them. Querying this graph can drive higher-level organizational outcomes such as audit, policy, risk management, and even developer assistance. Conceptually, GUAC occupies the “aggregation and synthesis” layer of the software supply chain transparency logical model: | Tool Vulnerability | Uber | |

Ransom Cartel Ransomware: A Possible Connection With REvil
(published: October 14, 2022)
Palo Alto Networks researchers analyzed Ransom Cartel, a double extortion ransomware-as-a-service group. Ransom Cartel came to existence in mid-December 2021 after the REvil group shut down. The Ransom Cartel group uses the Ransom Cartel ransomware, which shares significant code similarities with REvil, indicating close connections, but lacks REvil obfuscation engine capabilities. Ransom Cartel has almost no obfuscation outside of the configuration: unlike REvil it does not use string encryption and API hashing. Among multiple tools utilized by Ransom Cartel, the DonPAPI credential dumper is unique for this group. It performs Windows Data Protection API (DPAPI) dumping by targeting DPAPI-protected credentials such as credentials saved in web browsers, RDP passwords, and Wi-Fi keys.
Analyst Comment: Network defenders should consider monitoring or blocking high-risk connections such as TOR traffic that is often abused by Ransom Cartel and its affiliates. It is crucial that your company ensure that servers are always running the most current software version. Your company should have policies in place in regards to the proper configurations needed for your servers in order to conduct your business needs safely.

Alchimist and Insekt binaries are implemented in GoLang.This campaign consists of additional bespoke tools such as a MacOS exploitation tool, a custom backdoor and multiple off-the-shelf tools such as reverse proxies. Cisco Talos has discovered a new single-file command and control (C2) framework the authors call "Alchimist [sic]." Talos researchers found this C2 on a server that had a file listing active on the root directory along with a set of post-exploitation tools.Cisco Talos assesses with moderate-high confidence that this framework is being used in the wild. "Alchimist" is a 64-bit Linux executable written in GoLang and packed with assets including resources for the web interface and Insekt RAT payloads compiled for Windows and Linux. Insekt RAT, a new trojan Cisco Talos discovered, is Alchimist's beacon implant written in GoLang and has a variety of remote access capabilities that can be instrumented by the Alchimist C2 server.Alchimist C2 has a web interface written in Simplified Chinese and can generate a configured payload, establish remote sessions, deploy payload to the remote machines, capture screenshots, perform remote shellcode execution and run arbitrary commands. Among the remaining tools, Cisco Talos found a Mach-O dropper embedded with an exploit to target a known vulnerability CVE-2021-4034, a privilege escalation issue in polkit's pkexec utility, and a Mach-O bind shell backdoor. The Qualys Research Team discovered CVE-2021-4034 in November 2021, and in January 2022, the U.S.'s National Security Agency Cybersecurity Director warned that the vulnerability was being exploited in the wild. The server also contained dual-use tools like psexec and netcat, along with a scanning tool called "fscan," which the author defines as an "intranet scanning tool," essentially all the necessary tools for lateral movement. Alchimist framework The attack framework we discovered during the course of this research consists of a standalone C2 server called "Alchimist" and its corresponding implants the authors call the "Insekt" RAT family.Alchimist isn't the first self-contained framework we've discovered recently, with Manjusaka being another single file-based C2 framework disclosed by Talos recently. Both follow the same design philosophy, albeit implemented in different ways, to the point where they both seem to have the same list of requirements despite being implemented by different programmers.

VMware Report Exposes Emotet Malware’s Supply Chain
(published: October 10, 2022)
VMware researchers analyzed the Emotet malware-as-a-service evolution and its command-and-control (C2) infrastructure. In June 2022, Emotet added two new modules: one stealing credit card information from Google Chrome browsers, and another one that leverages the SMB protocol to spread laterally. Emotet’s main component is a DLL file that stores a highly obfuscated list of C2 IP:port pairs. More than half of the ports counted were port 8080 used as a proxy port on compromised legitimate servers abused to proxy traffic to the real C2 servers.
Analyst Comment: For network defenders it is important to strengthen email security and implement network segmentation whenever possible. Despite its continuous evolution, Emotet botnets can reuse previously identified infrastructure. Block known network-based indicators available via Anomali platform.

LofyGang Hackers Built a Credential-Stealing Enterprise on Discord, NPM
(published: October 7, 2022)
Checkmarx Security researchers described a financially-motivated threat actor group dubbed LofyGang (Lofy). This group aims at stealing credentials and credit card data by distributing approximately 200 malicious packages and fake hacking tools on code-hosting platforms, such as NPM and GitHub. LofyGang uses package name typosquatting and the starjacking technique of displaying fake popularity statistics. The first LofyGang package typically does not have a malicious behavior besides getting the second-stage malicious package. For its command-and-control communication the group often abuses legitimate services such as Discord, GitHub, glitch, Heroku, and Repl.it.

2022-10-12 02:00:00 | Top considerations when choosing a multi-factor authentication solution (lien direct) | Passwords clearly are not enough to protect networks. Any security guidance will tell you that multi-factor authentication (MFA) is a key method to keep attackers out. But what type of MFA should your firm deploy? Choosing multi-factor tokens and tools depends on your firm, your needs, and how attackers are likely to target your firm. Planning ahead will minimize deployment and migration issues when new tokens or new phones are issued.These are the most important considerations when choosing an MFA solution.Know what the MFA solution will and will not protect You have several decisions to make when deciding what MFA tool to use. First, review how the tool protects your network. Often when adding MFA to existing on-premises applications, it may not fully protect your organization from some attacks. Case in point is the recent Exchange Server zero-day attack. MFA in this situation did not protect servers. At least one victim used on-premises Exchange Server with a third-party MFA application. While it protected parts of the authentication process, it did not protect Outlook Web Access (OWA), which uses basic authentication. MFA didn't protect that part of the site, so the attackers could go around MFA and attack the servers. Consider exactly what the MFA solution you choose protects, then review what authentication processes are still exposed.To read this article in full, please click here | Tool | ||

2022-10-11 10:00:00 | PCI DSS v4.0 (lien direct) | 2022 is the year that much of the world managed, to varying degrees of success, to get back to normal. People ramped up traveling, returned to in-person activities and many returned to the office. The pandemic changed most aspects of day-to-day life, but hackers and other bad actors generally continued making life difficult for businesses, governments, and non-profit entities. As a result, there have been some innovative new ways to target networks and IT infrastructures that keep CISOs and their teams up at night. A sample of those types of concerning threat vectors include Ransomware as a Service, targeting IOT/OT infrastructure, general supply chain attacks. Tried and true methods, like phishing, and targeting unpatched or outdated systems to find vulnerabilities also continued. Data shows that threats are increasing in volume and impact across every industry and government agency. The Cybersecurity and Infrastructure Security Agency (CISA) recently reported that 14 critical US sectors have been the subject to intense ransomware attacks and the FBI identified over 2,000 ransomware attacks between January and July of 2022. (source) CheckPoint estimates that 1 out of 40 organizations will be hit by a ransomware attack and 84% of those sees some amount of data exfiltration. IBM appraises the average cost of a data breach at $4.3M and the recovery time from such attacks is approximately 22 days. And with all of that said, the World Economic Forum still attributes 95% of all data breaches to human error. The cybersecurity industry is fighting back. The PCI Security Standards Council (PCI SSC) sorted through over 6,000 pieces of feedback from over 200 organizations, to help it create the new standard aimed at significantly reducing the success of these types of attacks in the future. On May 31, 2022, the PCI SSC released version 4.0 of the Payment Card Industry Data Security Standard (PCI DSS). This provides an accepted baseline of technical and operational requirements designed to protect various types of user account data. The updated standard and Summary of Changes document are available now on the PCI SSC website. Version 4.0 is a significant update to the standard, so to enable organizations to understand the new requirements and plan, execute and test updates, the current version of 3.2.1 remains active through March 31, 2024. Assessors are undergoing training and certification for the new standard now, and once available, they will be able to assess to either the current or new standard, based upon the plans of the organization. The new standard had many expected updates based upon evolving payment card industry security needs. There are also changes to the frequency of expected effort, shifting from specific durations between work to the idea that security is a continuous process. The stated goals for PCI DSS v4.0 are as follows: Continue to Meet the Security Needs of the Payment Industry; Promote Security as Continuous Process; Add Flexibility for Different Meth | Ransomware Data Breach Tool Vulnerability Threat Guideline | ||

2022-10-07 10:00:00 | Ransomware - undeniably top of mind (lien direct) | A brief walk down memory lane: Ransomware is not a new threat Ransomware’s first documented attack was relatively rudimentary. It was delivered via floppy disk containing a malware program in 1989 that told its victims to pay $189 in ransom to a PO Box in Panama. Today ransomware criminals are significantly more sophisticated, thanks to advances in cyber methods and cryptocurrencies. Not all Ransomware is created equally. Like all malware, malicious codes vary in sophistication and modularity. As such, not all ransomware codes are made the same. While some are ordinary and even obtained freely on open-source platforms and forums, others are highly sophisticated and operated exclusively by elite cybercrime syndicates. How do we prepare for a ransomware incident? Overcoming a ransomware incident is all about preparation while responding with uncertainty identifies the lack of an effective plan. Today’s media coverage is mainly focused on how Ransomware affects people. Unless you are in the cybersecurity profession or aspiring to be, you may be unaware that Ransomware is no different than other malicious software. The same cybersecurity tools and processes to protect systems from trivial malware like crypto miners are the same for Ransomware. The media is not covering stories about malicious software performing cryptocurrency mining operations as an end-user because the only thing stolen by malicious crypto mining software is processor time. Align to a model, describe, and communicate A good plan must be easy to communicate and measure, and there are several organizations that offer helpful frameworks and recommendations such as NIST and CISA. As you analyze what is best for your organization, consider the ever-changing threat landscape and how you plan to adjust. The following model offers an agile approach to reducing the risk of a ransomware incident: Assess – identify gaps including people, process, and technology (where are we today?) Plan – take action to address gaps (enable measurement) Practice – test people, process, and technology (phishing, social engineering) Measure – how are we doing? identify remaining gaps Adjust – close remaining gaps Testing is a critical to step to confirming technology, people, and process work cohesively, yet is often overlooked. As you establish your plan, emphasize testing and measurements to ensure the desired outcomes are being obtained. Communicate with key stakeholders and align to promote a culture of awareness. The elephant in the room: To pay or not to pay: All businesses need to be prepared for “if, not when.” Cyber criminals exploit vulnerabilities, not always a specific business. The average time to dwell is closing in on 300 days. Once exploited, a malicious actor can work their way to financial information. If financial information is known, the ransom is set at our below an expected threshold. This is critical for small and medium businesses due to limited resources and ownership having extreme emotional ties to the firm. Malicious actors strike on the emotional vulnerability and negotiate payment based on known financials. Establishing a plan is critical to reducing the risk of emotion driving the decision to pay. Paying a ransom is a business financial decision, like converting cash to crypto on your balance sheet. It can also be considered illegal and not an option as you effectively support terrorism. Outside of legal issues, something to consider: How much data entry must be inputted to offset from the last backup? Is this possible/feasible? Often this amount exceeds the ransom demand.

2022-10-06 10:34:00 | BrandPost: Overcoming Cybersecurity Implementation Challenges (lien direct) | Cybersecurity has long been one of the most complex landscapes an organization must navigate; with each new threat or vulnerability, complexity continues to grow. This is especially true for organizations that have traditionally taken a point product approach to their security because implementing new security measures properly and reliably takes time and expertise. Today, as more businesses look to digitize their services, dealing with these cybersecurity challenges is no longer optional.Every new tool must be installed, tested, and validated, and then people must be trained to leverage them well. On average, organizations are adopting dozens of different products, services, and tools for their cybersecurity. So, finding ways to make implementing cybersecurity smoother, faster, and more efficient has become a key goal for cybersecurity professionals. As businesses plan for a post-pandemic and digitally accelerated era, many CISOs across multiple industries strive for simplicity and focus on reducing their security vendor blueprint as part of their annual KPIs. Implementation, in particular, has always been an important consideration for successful cybersecurity programs because of the time, expense, personnel, and expertise often required not only to implement individual point products but to stitch them together in order to avoid security gaps while also eliminating redundancies. In the event of a serious incident, security operations center (SOC) analysts typically confess to switching between multiple vendor consoles and event types in order to decipher alerts. Organizations and teams need a better approach, so they're not either continually exposed or overworked from the alerts created by overlap.To read this article in full, please click here | Tool Threat | ||

New Royal Ransomware Emerges in Multi-Million Dollar Attacks
(published: September 29, 2022)
AdvIntel and BleepingComputer researchers describe the Royal ransomware group. Several experienced ransomware actors formed this group in January 2022. It started with third-party encryptors such as BlackCat, switched to using its own custom Zeon ransomware, and, since the middle of September 2022, the Royal ransomware. Royal group utilizes targeted callback phishing attacks. Its phishing emails impersonating food delivery and software providers contained phone numbers to cancel the alleged subscription (after the alleged end of a free trial). If an employee calls the number, Royal uses social engineering to convince the victim to install a remote access tool, which is used to gain initial access to the corporate network.
Analyst Comment: Use services such as Anomali's Premium Digital Risk Protection to detect the abuse of your brands in typosquatting and phishing attacks. Organizations should include callback phishing attacks awareness into their anti-phishing training.

ZINC Weaponizing Open-Source Software
(published: September 29, 2022)
Microsoft researchers described recent developments in Lazarus Group (ZINC) campaigns that start from social engineering conversations on LinkedIn. Since June 2022, Lazarus was able to trojanize several open-source tools (KiTTY, muPDF/Subliminal Recording software installer, PuTTY, TightVNC, and Sumatra PDF Reader). When a target extracts the trojanized tool from the ISO file and installs it, Lazarus is able to deliver their custom malware such as EventHorizon and ZetaNile. In many cases, the final payload was not delivered unless the target manually established an SSH connection to an attacker-controlled IP address provided in the attached ReadMe.txt file.
Analyst Comment: All known indicators connected to this recent Lazarus Group campaign are available in the Anomali platform and customers are advised to block these on their infrastructure. Researchers should monitor for the additional User Execution step required for payload delivery. Defense contractors should be aware of advanced social engineering efforts abusing LinkedIn and other means of establishing trusted communication.

Executive summary
The Mirai botnet is infamous for the impact and the everlasting effect it has had on the world. Since the inception and discovery of this malware in 2016, to present day and all the permutations that have spawned as a result, cybersecurity professionals have been keeping a keen eye on this form of Command and Control (C2 or CnC) malware and associated addresses. The botnet malware utilizes malicious IP addresses that serve as intermediaries between compromised hosts and the central command server, which can use a wide range of Technique’s, Tactics, and Procedures (TTP’s) to deliver a payload in line with the malicious actor's goals.
Recently, one of these malicious IP addresses reached out to an asset in an organization over port 22 and created an unmitigated Secure Shell (SSH) session to the company's file server, a breach that was mitigated by the security best practices of this company preventing any follow up or lateral movement in the environment. This breach ultimately resulted in the IP getting blocklisted and stopped due to a healthy security posture that prevented malicious pivoting or exploitation.
Investigation
Initial alarm review
Indicators of Compromise (IOC)
The alarm initially came in due to an inbound connection from a known malicious IP as reported by the Open Threat Exchange (OTX) pulse related to Mirai botnet activity. OTX is open source threat sharing platform that contains a wide variety of Indicators of Compromise (IOC’s) that leverage user submitted data and the collective cybersecurity world to form an ever-evolving threat landscape.
The evidenced corresponding action ‘InboundConnectionAccepted’ is self-explanatory in that the connection was not mitigated and there was communication taking place over port 22. The associated event further detailed this inbound connection with the initiating processes, logged on user, and process parents. This revealed that the affected asset is a fileserver managed by SolarWinds software and it was likely this inbound connection was accepted in part due to typical network behavior and stateful firewall rules.
Expanded investigation
Events search
C2 activity typically utilizes positive feedback to gain persistence, relying on some sort of beacon placed in the victim’s environment that lets the attacker know there is a device or network ready for command execution. After seeing a successful connection occur with the malicious IP, the next step was to determine if the malicious IP address had further infiltrated the environment or attempted any lateral movement. A thorough search in the instance showed only the single referenced event as it pertains to the malicious IP however, the contextual events surrounding this successful connection corroborate attempted C2 activity.
Event deep dive
A further look into the event associated with the alarm shows that this is a fileserver utilizing Serv-U.exe, a File Transfer Protocol (FTP) software created by SolarWinds. The destination port 22 successfully hosted communication with the malicious IP and appears to have been automatically proxied by the software, which could also contribute to the reason this connection was accepte |

A Multimillion Dollar Global Online Credit Card Scam Uncovered
(published: September 23, 2022)
ReasonLabs researchers discovered a large network of fake dating and customer support websites involved in credit card fraud operations. The threat actor builds a basic website, registers it with a payment processor (RocketGate), buys credit card data from other threat actors, and subscribes victims to monthly charging plans. The US was the most targeted, and a lower number of sites were targeting France. To pass the processor checks and lower the number of charge-backs the actor avoided test charges, used a generic billing name, charged only a small, typical for the industry payment, and hired a legitimate support center provider, providing effortless canceling and returning of the payment.
Analyst Comment: Users are advised to regularly check their bank statements and dispute fraudulent charges. Researchers can identify a fraudulent website by overwhelming dominance of direct-traffic visitors from a single country, small network of fake profiles, and physical address typed on a picture to avoid indexing.

Malicious OAuth Applications Used to Compromise Email Servers and Spread Spam
(published: September 22, 2022)
Microsoft researchers described a relatively stealthy abuse of a compromised Exchange server used to send fraud spam emails. After using valid credentials to get access, the actor deployed a malicious OAuth application, gave it admin privileges and used it to change Exchange settings. The first modification created a new inbound connector allowing mails from certain actor IPs to flow through the victim’s Exchange server and look like they originated from the compromised Exchange domain. Second, 12 new transport rules were set to delete certain anti-spam email headers.
Analyst Comment: If you manage an Exchange server, strengthen account credentials and enable multifactor authentication. Investigate if receiving alerts regarding suspicious email sending and removal of antispam header.

2022-09-27 10:00:00 | Centralized Privacy Center: The key to meeting data privacy obligations (lien direct) | This blog was written by an independent guest blogger. Website owners generally have privacy policies and terms of service since they are necessary for compliance and ensuring website visitors get a personalized experience. As digital needs transform and data privacy laws evolve in nature, website owners that collect data are required to have a Privacy Center. Hundreds of millions of users share their personal information on websites, enabling websites to effectively interact with their users, innovate and grow their business. Businesses must ensure that websites maintain their customers' trust in handling their data, which gives shape to functions like a Privacy Center. What is a Privacy Center? From a user perspective, a Privacy Center makes it simple for users to maintain control over their personal information that has been shared with a website. For a business, a Privacy Center provides all the information users require about privacy policies, cookie policies, data subject access requests, do not track or sell, and much more in one accessible spot. Data privacy laws such as the European Union’s General Data Protection Regulations (GDPR) and the United States’ California Privacy Rights Act (CPRA)/California Consumer Privacy Act (CCPA) impose strict obligations on businesses regarding data processing activities, the usage of privacy policies, and transparent privacy practices. Consequently, businesses are increasingly coming to terms with the significance of Privacy Centers and how they can improve their compliance processes to avoid non-compliance penalties and make it easy to publish or update relevant policies from a single platform. What does a Privacy Center address? Data privacy laws regulate how companies manage users' personal data, and users' awareness of their digital rights only escalates the need for a privacy center to address the following main concerns: What private information of a user can a business access? How does the business handle personal data of users? What is the purpose of collecting this personal data? Does the business sell or share the personal data with third parties? How long does a company retain the personal data of users? Is there an option of opt-out or unsubscribing from receiving personalized services? Businesses can efficiently address these issues and others from a single platform on their website, such as Securiti’s Privacy Center. The tool is designed to address: Privacy Policy Terms of Service Cookie Policy Consent & Third Party Data Subject Requests Do Not Sell or Track When and why should a business have a Privacy Center? A Privacy Center, instead of separate policies for cookies, privacy policies, and others, is a user-friendly approach to disclosing data collection and processing activities. Large volumes of data collected If a business collects troves of data, a Privacy Center will enable the business to be transparent regarding data collection, processing, and sharing activities without overwhelming users. Looking for a single piece of information through a lengthy Privacy Policy page can be confusing and nerve-racking. A Privacy Center is an ideal platform for revealing various information in an understandable format. It is also simple for a user to locate relevant information without sifting through mountains of text. | Tool | ||
