New MuddyWater Threat: Old Kitten; New Tricks
(published: December 8, 2022)
In 2020-2022, Iran-sponsored MuddyWater (Static Kitten, Mercury) group went through abusing several legitimate remote administration tools: RemoteUtilities, followed by ScreenConnect and then Atera Agent. Since September 2022, a new campaign attributed to MuddyWater uses spearphishing to deliver links to archived MSI files with yet another remote administration tool: Syncro. Deep Instinct researchers observed the targeting of Armenia, Azerbaijan, Egypt, Iraq, Israel, Jordan, Oman, Qatar, Tajikistan, and United Arab Emirates.
Analyst Comment: Network defenders are advised to establish a baseline for typical running processes and monitor for remote desktop solutions that are not common in the organization.

Babuk Ransomware Variant in Major New Attack
(published: December 7, 2022)
In November 2022, Morphisec researchers identified a new ransomware variant based on the Babuk source code that was leaked in 2021. One modification is lowering detection by abusing the legitimate Microsoft signed process: DLL side-loading into NTSD.exe — a Symbolic Debugger tool for Windows. The mechanism to remove the available Shadow Copies was changed to using Component Object Model objects that execute Windows Management Instrumentation queries. This sample was detected in a large, unnamed manufacturing company where attackers had network access and were gathering information for two weeks. They have compromised the company’s domain controller and used it to distribute ransomware to all devices within the organization through Group Policy Object. The delivered BAT script bypasses User Account Control and executes a malicious MSI file that contains files for DLL side-loading and an open-source-based reflective loader (OCS files).
Analyst Comment: The attackers strive to improve their evasion techniques, their malware on certain steps hides behind Microsoft-signed processes and exists primarily in device memory. It increases the need for the defense-in-depth approach and robust monitoring of your organization domain.

2022-12-13 11:00:00 | 2023 Cybersecurity predictions (lien direct) | Cybersecurity is a relatively new discipline in the realm of computing. Once computing became more democratized with PCs connected via local area networks (LAN) and client/server environments, adversaries quickly saw opportunities. The more democratized computing – the more risk and the potential for cyber adversaries.
Dealing with cyber risk and adversaries is now part of a normal business plan. Gone are the days of instilling fear, uncertainty, and doubt (FUD) about the potential of a bad actor. The days of nefarious hackers in hoodies lurking in the shadows are gone.
Businesses of all types and sizes now know that cybersecurity is part of a solid business plan. Security is no longer relegated to a team of really smart experts; security is a business enabler and builder of digital trust.
As we move to 2023, we will continue to see computing more democratized. With the advent of more edge computing (according to the 2022 AT&T Cybersecurity Insights Report, 75% of organizations are on a journey to the edge, the way we interact with technology is rapidly shifting. We are moving from input/output types of functions to more seamless interactions that deliver outcomes.
With more of a focus on outcomes, security becomes the center of focus in the new democratized era of computing. We are just getting started with ideas for edge computing. And, by association, we are just getting started with what security means.
Here are my predictions for some of the trends and highlights we will see in cybersecurity landscape in the year ahead.
Move to the edge
A new paradigm of computing is upon us. This new era is underpinned by 5G and edge.
Edge is a word we have heard for quite some time, but in general conversation lacks a consistent definition. Vendors and business users alike tend to define edge in accordance with the technology stack being sold or used.
When thinking about edge, consider these three characteristics as a starting point:
A distributed model of management, intelligence, and networks
Applications, workloads, and hosting closer to users and assets that are generating or consuming the data – may be on-premise or in the cloud
Software defined
Edge use cases are largely driven by the world of the internet of things (IoT) that collect and transmit data to make logical and rational decisions to derive an outcome.
In 2023, we should expect to see an accelerated full-scale rollout of edge use cases in areas such as:
Real-time fraud detection for financial services
Automated warehousing with near real-time inventory management
Near real-time visual inspections for uses as varied as manufacturing assembly lines, passport control at border crossing, and available parking spaces
These use cases require connected systems from the network layer through to application monitoring/management, and require each component to be secure in order to derive the desired outcome.
With more democratized computing, security is no longer isolated, it is central to delivering strong business outcomes.
In 2023, expect to see more edge use cases and applications. For successful implementation and with security at the core, expect to see the erosion of decades-old siloes such as networking, IT, app development, and security begin to fade away and enable more cross-functional work and roles.

Chinese Gambling Spam Targets World Cup Keywords
(published: December 2, 2022)
Since 2018, a large-scale website infection campaign was affecting up to over 100,000 sites at a given moment. Infected websites, mostly oriented at audiences in China, were modified with additional scripts. Compromised websites were made to redirect users to Chinese gambling sites. Title and Meta tags on the compromised websites were changed to display keywords that the attackers had chosen to abuse search engine optimization (SEO). At the same time, additional scripts were switching the page titles back to the original if the visitor fingerprinting did not show a Chinese search engine from a preset list (such as Baidu).
Analyst Comment: Website owners should keep their systems updated, use unique strong passwords and introduce MFA for all privileged or internet facing resources, and employ server-side scanning to detect unauthorized malicious content. Implement secure storage for website backups.

Leaked Android Platform Certificates Create Risks for Users
(published: December 2, 2022)
On November 30, 2022, Google reported 10 different Android platform certificates that were seen actively abused in the wild to sign malware. Rapid7 researchers found that the reported signed samples are adware, so it is possible that these platform certificates may have been widely available. It is not shared how these platform certificates could have been leaked.
Analyst Comment: Malware signed with a platform certificate can enjoy privileged execution with system permissions, including permissions to access user data. Developers should minimize the number of applications requiring a platform certificate signature.

DEV-0569 Finds New Ways to Deliver Royal Ransomware, Various Payloads
(published: November 17, 2022)
From August to October, 2022, Microsoft researchers detected new campaigns by a threat group dubbed DEV-0569. For delivery, the group alternated between delivering malicious links by abusing Google Ads for malvertising and by using contact forms on targeted organizations’ public websites. Fake installer files were hosted on typosquatted domains or legitimate repositories (GitHub, OneDrive). First stage was user-downloaded, signed MSI or VHD file (BatLoader malware), leading to second stage payloads such as BumbleBee, Gozi, Royal Ransomware, or Vidar Stealer.
Analyst Comment: DEV-0569 is a dangerous group for its abuse of legitimate services and legitimate certificates. Organizations should consider educating and limiting their users regarding software installation options. Links from alternative incoming messaging such as from contact forms should be treated as thorough as links from incoming email traffic.

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).

2022-10-18 08:41:18 | The benefits of taking an intent-based approach to detecting Business Email Compromise (lien direct) |  By Abhishek Singh.BEC is a multi-stage attack. Adversaries first identify targets, then they establish rapport with the victim before exploiting them for whatever their end goal is. In the case of BEC, a threat actor can impersonate any employee in the organization to trick targets. A policy that checks for authorized email addresses of the sender can prevent BEC attacks. However, scaling the approach for every employee in a large organization is a challenge. Building an executive profile based on email analysis using a machine learning model and scanning emails against that profile will detect BEC. Data collection for building and training machine learning algorithms can take time, though, opening a window of opportunity for threat actors to exploit. Detection of exploitation techniques such as lookalike domains and any differences in the email addresses in the "From" and "Reply-to" fields can also detect BEC messages. However, the final verdict cannot account for the threat actor's intent. The intent-based approach detects BEC and then classifies it into the type of scam. It catches BEC messages, irrespective of whether a threat actor is impersonating a C-level executive or any employee in an organization. Classification based on the type of scam can help identify which segment of an organization was targeted and which employees were being impersonated by the threat actor. The additional information will further assist in better designing preventive features to stop BEC. Business email compromise (BEC) is one of the most financially damaging online crimes. As per the internet crime 221 report, the total loss in 2021 due to BEC is around 2.4 billion dollars. Since 2013, BEC has resulted in a 43 billion dollars loss. The report defines BEC as a scam targeting businesses (not individuals) working with foreign suppliers and companies regularly performing wire transfer payments. Fraudsters carry out these sophisticated scams to conduct the unauthorized transfer of funds. This introduces the challenge of how to detect and block these campaigns as they continue to compromise organizations successfully. There are a variety of approaches to identifying BEC email messages, such as using policy to allow emails from authorized email addresses, detecting exploitation techniques used by threat actors, building profiles by analysis of emails, and validating against the profile to detect BEC. These approaches have a variety of limitations or shortcomings. Cisco Talos is taking a different approach and using an intent-based model to identify and block BEC messages. Before we get too deep into the intent-based model, take a deeper look at the commonly used approaches to block BEC from the simplistic through machine learning (ML) approaches. Policy-based detection The first place to start is with policy-based detection as it is one of the most common and simplistic approaches to blocking BEC campaigns. Let's start by looking at an example of a BEC email. |

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.

The campaign is meant to infiltrate organizations around the world for establishing long term access and subsequently exfiltrating data of interest to the adversary's nation-state.Talos has discovered the use of two known families of malware in these intrusions - VSingle and YamaBot.Talos has also discovered the use of a recently disclosed implant we're calling "MagicRAT" in this campaign. IntroductionCisco Talos observed North Korean state-sponsored APT Lazarus Group conducting malicious activity between February and July 2022. Lazarus has been previously attributed to the North Korean government by the U.S. Cybersecurity and Infrastructure Security Agency (CISA). The entry vectors involve the successful exploitation of vulnerabilities in VMWare products to establish initial footholds into enterprise networks, followed by the deployment of the group's custom malware implants, VSingle and YamaBot. In addition to these known malware families, we have also discovered the use of a previously unknown malware implant we're calling "MagicRAT."This campaign was previously partially disclosed by other security firms, but our findings reveal more details about the adversary's modus operandi. We have also observed an overlap of command and control (C2) and payload-hosting infrastructure between our findings and the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) June advisory that detailed continued attempts from threat actors to compromise vulnerable VMWare Horizon servers.In this research, we illustrate Lazarus Group's post-exploitation tactics, techniques and procedures (TTPs) to establish a foothold, perform initial reconnaissance, deploy bespoke malware and move laterally across infected enterprises. We also provide details about the activities performed by the attackers when the VSingle backdoor is instrumented on the infected endpoints.In this campaign, Lazarus was primarily targeting energy companies in Canada, the U.S. and Japan. The main goal of these attacks was likely to establish long-term access into victim networks to conduct espionage operations in support of North Korean govern |

Executive SummaryCisco Talos has discovered a new remote access trojan (RAT), which we are calling "MagicRAT," that we are attributing with moderate to high confidence to the Lazarus threat actor, a state-sponsored APT attributed to North Korea by the U.S. Cyber Security & Infrastructure Agency (CISA). This new RAT was found on victims that had been initially compromised through the exploitation of publicly exposed VMware Horizon platforms. While being a relatively simple RAT capability-wise, it was built with recourse to the Qt Framework, with the sole intent of making human analysis harder, and automated detection through machine learning and heuristics less likely.We have also found evidence to suggest that once MagicRAT is deployed on infected systems, it launches additional payloads such as custom-built port scanners. Additionally, we've found that MagicRAT's C2 infrastructure was also used to host newer variants of known Lazarus implants such as TigerRAT. The discovery of MagicRAT in the wild is an indication of Lazarus' motivations to rapidly build new, bespoke malware to use along with their previously known malware such as TigerRAT to target organizations worldwide.Actor profile |

WannaCry is a ransomware worm that spread rapidly through across a number of computer networks in May of 2017. After infecting a Windows computer, it encrypts files on the PC's hard drive, making them impossible for users to access, then demands a ransom payment in bitcoin in order to decrypt them.A number of factors made the initial spread of WannaCry particularly noteworthy: it struck a number of important and high-profile systems, including many in Britain's National Health Service; it exploited a Windows vulnerability that was suspected to have been first discovered by the United States National Security Agency; and it was tentatively linked by Symantec and other security researchers to the Lazarus Group, a cybercrime organization that may be connected to the North Korean government.To read this article in full, please click here | Ransomware Vulnerability Medical | Wannacry Wannacry APT 38 | |

APT-C-35: New Windows Framework Revealed
(published: August 11, 2022)
The DoNot Team (APT-C-35) are India-sponsored actors active since at least 2016. Morphisec Labs researchers discovered a new Windows framework used by the group in its campaign targeting Pakistani government and defense departments. The attack starts with a spearphishing RTF attachment. If opened in a Microsoft Office application, it downloads a malicious remote template. After the victim enables editing (macroses) a multi-stage framework deployment starts. It includes two shellcode stages followed by main DLL that, based on victim fingerprinting, downloads a custom set of additional information-stealing modules.
Analyst Comment: The described DoNot Team framework is pretty unique in its customisation, fingerprinting, and module implementation. At the same time, the general theme of spearphishing attachment that asks the targeted user to enable editing is not new and can be mitigated by anti-phishing training and Microsoft Office settings hardening.

2022-07-07 08:14:35 | North Korean State-Sponsored Threat Actors Deploying "MAUI" Ransomware (lien direct) | Today, the United States Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Agency (CISA) and the Department of Treasury released a joint Cybersecurity Advisory on Maui Ransomware, which is attributed to state sponsored activity by the government of North Korea. The Joint CSA provides detailed insight on the various TTPs used by the threat actors behind Maui, which has targeted the Health and Public Health Sector.How Serious of an Issue is This?High. As ransomware activity causes downtime, theft of confidential and personally identifiable information (PII) and other significant impact to operations, it is important to ensure that various security measures are in place, like being up to date with patching vulnerable machines/infrastructure. Also, ensuring employees are trained and up to date on various social engineering attempts and tactics used by threat actors will be a first line of defense against such attacks.What is Maui Ransomware?Maui ransomware is unique in a way that it requires manual execution to start the encryption routine. Maui also features a CLI (command line interface) that is used by the threat actor to target specific files to encrypt. Maui also has the ability to identify previously encrypted files due to customer headers containing the original path of the file.Who are HIDDEN COBRA/LAZARUS/APT38/BeagleBoyz?HIDDEN COBRA also known as Lazarus/APT38/BeagleBoyz has been atributed to the government of North Korea. Also, they have been linked to multiple high-profile, financially-motivated attacks in various parts of the world - some of which have caused massive infrastructure disruptions. Notable attacks include the 2014 attack on a major entertainment company and a 2016 Bangladeshi financial institution heist that almost netted nearly $1 Billion (USD) for the attackers. Had it not been for a misspelling in an instruction that caused a bank to flag and block thirty transactions, HIDDEN COBRA would have pulled off a heist unlike any other. Although HIDDEN COBRA failed in their attempt, they were still able to net around 81 million dollars in total.The most recent notable attack attributed to HIDDEN COBRA was the Wannacry Ransomware attack, which resulted in massive disruption and damage worldwide to numerous organizations, especially those in manufacturing. Various estimates of the impact were in the hundreds of millions of dollars, with some estimates claiming billions. Other verticals which this group has targeted include critical infrastructures, entertainment, finance, healthcare, and telecommunication sectors across multiple countries.Who are the BeagleBoyz?The BeagleBoyz group is a newly identified group that is a subset of activity by the threat actors known as HIDDEN COBRA/LAZARUS/APT 38 and has been observed committing financial crimes, specifically cryptocurrency related thefts. Further information about the BeagleBoyz can be found here.What Operating Systems are Affected?Windows based operating systems are affected.What is the Status of Coverage?Fortinet customers running the latest definitions are protected against Maui with the following (AV) signatures:W32/Ransom_Win32_MAUICRYPT.YACC5W32/Agent.C5C2!trW32/PossibleThreatAnything Else to Note?Victims of ransomware are cautioned against paying ransoms by such organizations as CISA, NCSC, the FBI, and HHS. Payment does not guarantee files will be recovered. It may also embolden adversaries to target additional organizations, encourage other criminal actors to engage in the distribution of ransomware, and/or fund illicit activities which could potentially be illegal according to a U.S. Department of Treasury's Office of Foreign Assets Control (OFAC) advisory. | Threat Ransomware Patching Medical | Wannacry Wannacry APT 38 | |

SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems
(published: April 25, 2022)
Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables.
Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

Lazarus Targets Chemical Sector
(published: April 14, 2022)
In January 2022, Symantec researchers discovered a new wave of Operation Dream Job. This operation, attributed to the North Korea-sponsored group Lazarus, utilizes fake job offers via professional social media and email communications. With the new wave of attacks, Operation Dream Job switched from targeting the defense, government, and engineering sectors to targeting South Korean organizations operating within the chemical sector. A targeted user executes an HTM file sent via a link. The HTM file is copied to a DLL file to be injected into the legitimate system management software. It downloads and executes the final backdoor: a trojanized version of the Tukaani project LZMA Utils library (XZ Utils) with a malicious export added (AppMgmt). After the initial access, the attackers gain persistence via scheduled tasks, move laterally, and collect credentials and sensitive information.
Analyst Comment: Organizations should train their users to recognize social engineering attacks including those posing as “dream job” proposals. Organizations facing cyberespionage threats should implement a defense-in-depth approach: layering of security mechanisms, redundancy, fail-safe defense processes.
