LastPass Hackers Stole Source Code
(published: August 26, 2022)
In August 2022, an unidentified threat actor gained access to portions of the password management giant LastPass development environment. LastPass informed that it happened through a single compromised developer account and the attacker took portions of source code and some proprietary LastPass technical information. The company claims that this incident did not affect customer data or encrypted password vaults.
Analyst Comment: This incident doesn’t seem to have an immediate impact on LastPass users. Still, organizations relying on LastPass should raise the concern in their risk assessment since “white-box hacking” (when source code of the attacking system is known) is easier for threat actors. Organizations providing public-facing software should take maximum measures to block threat actors from their development environment and establish robust and transparent security protocols and practices with all third parties involved in their code development.

Mercury Leveraging Log4j 2 Vulnerabilities in Unpatched Systems to Target Israeli
(published: August 25, 2022)
Starting in July 2022, a new campaign by Iran-sponsored group Static Kitten (Mercury, MuddyWater) was detected targeting Israeli organizations. Microsoft researchers detected that this campaign was leveraging exploitation of Log4j 2 vulnerabilities (CVE-2021-45046 and CVE-2021-44228) in SysAid applications (IT management tools). For persistence Static Kitten was dropping webshells, creating local administrator accounts, stealing credentials, and adding their tools in the startup folders and autostart extensibility point (ASEP) registry keys. Overall the group was heavily using various open-source and built-in operating system tools: eHorus remote management software, Ligolo reverse tunneling tool, Mimikatz credential theft tool, PowerShell programs, RemCom remote service, Venom proxy tool, and Windows Management Instrumentation (WMI).
Analyst Comment: Network defenders should monitor for alerts related to web shell threats, suspicious RDP sessions, ASEP registry anomaly, and suspicious account creation. Similarly, SysAid users can monitor for webshells and abnormal processes related to SysAisServer instance. Even though Static Kitten was observed leveraging the Log4Shell vulnerabilities in the past (targeting VMware apps), most of their attacks still start with spearphishing, often from a compromised email account.

2022-08-30 08:00:09 | ModernLoader delivers multiple stealers, cryptominers and RATs (lien direct) |  By Vanja SvajcerCisco Talos recently observed three separate, but related, campaigns between March and June 2022 delivering a variety of threats, including the ModernLoader bot, RedLine information-stealer and cryptocurrency-mining malware to victims. The actors use PowerShell, .NET assemblies, and HTA and VBS files to spread across a targeted network, eventually dropping other pieces of malware, such as the SystemBC trojan and DCRAT, to enable various stages of their operations. The attackers' use of a variety of off-the-shelf tools makes it difficult to attribute this activity to a specific adversary.The final payload appears to be ModernLoader, which acts as a remote access trojan (RAT) by collecting system information and deploying various modules. In the earlier campaigns from March, we also observed the attackers delivering the cryptocurrency mining malware XMRig. The March campaigns appeared to be targeting Eastern European users, as the constructor utility we analyzed had predefined script templates written in Bulgarian, Polish, Hungarian and Russian.The actors are attempting to compromise vulnerable web applications to serve malware and deliver threats via files masquerading as fake Amazon gift cards. Technical detailsInitial findingsIn June 2022, Cisco Talos identified an unusual command line execution in our telemetry.

On the other hand, it also means you now have to deal with how hardware timers actually work, which introduces its own flavors of weird timing variations.Introduction I recently discovered a race condition (https://crbug.com/project-zero/2247) in the Linux kernel. (While trying to explain to someone how the fix for CVE-2021-0920 worked - I was explaining why the Unix GC is now safe, and then got confused because I couldn't actually figure out why it's safe after that fix, eventually realizing that it actually isn't safe.) It's a fairly narrow race window, so I was wondering whether it could be hit with a small number of attempts - especially on kernels that aren't built with CONFIG_PREEMPT, which would make it possible to preempt a thread with another thread, as I described at LSSEU2019. This is a writeup of how I managed to hit the race on a normal Linux desktop kernel, with a hit rate somewhere around 30% if the proof of concept has been tuned for the specific machine. I didn't do a full exploit though, I stopped at getting evidence of use-after-free (UAF) accesses (with the help of a very large file descriptor table and userfaultfd, which might not be available to normal users depending on system configuration) because that's the part I was curious about. This also demonstrates that even very small race conditions can still be exploitable if someone sinks enough time into writing an exploit, so be careful if you dismiss very small race windows as unexploitable or don't treat such issues as security bugs.

Reservations Requested: TA558 Targets Hospitality and Travel
(published: August 18, 2022)
Since 2018, financially-motivated threat group TA558 has targeted hospitality and travel with reservation-themed, business-relevant phishing emails. The group concentrates on targeting Latin America using lures written in Portuguese and Spanish, and sometimes uses English and wider targeting (North America, Western Europe). TA558 was seen leveraging at least 15 different malware payloads, most often AsyncRAT, Loda RAT, Revenge RAT, and Vjw0rm. In 2022, Proofpoint researchers detected that TA558 increased its activity and moved from using malicious macros to URLs and container files (ISO, RAR).
Analyst Comment: Microsoft’s preparations to disable macros by default in Office products caused multiple threat groups including TA558 to adopt new filetypes to deliver payloads. It is crucial for personnel working with invoices and other external attachments to use updated, secured systems and be trained on phishing threats. Anomali Match can be used to quickly search your infrastructure for known TA558 IOCs.

Estonia Subjected to 'Extensive' Cyberattacks after Moving Soviet Monuments
(published: August 18, 2022)
On August 17, 2022, Russian hacktivist group KillNet launched distributed denial-of-service (DDoS) attacks targeting Estonia. The Estonian government confirmed receiving the “most extensive” DDoS attacks in 15 years, but stressed that all services are back online after just some minor interruptions. Small and medium-sized DDoS attacks targeted 16 state and private organizations in the country, with seven of them experiencing downtime as a result. Specifically, the Estonian Tax and Customs Board website was unavailable for about 70 minutes.
Analyst Comment: Russian cyber activity follows political tensions, this time coinciding with the removal of a Red Army memorial. Estonia seemingly easily fended off this Russian DDoS attack, but the country is one of the top in cyber preparedness, and Russia limited it’s strike to using hacktivist groups that give plausible deniability when attributing the cyber attack on a NATO country.

2022-08-23 10:00:00 | Establishing a mobile device vulnerability management program (lien direct) | The introduction of mobile devices has rapidly changed the world as we know it, as these small gadgets that are intended to fit into the palm of our hands rapidly gained dominance over our day-to-day activities. Thanks to these portable devices, we now have access to an abundance of information available to us on demand with minimal effort.
Mobile devices have become so powerful that your cellphone contains significant data about you as individual through your data storage, communication activities (social media, e-mail, text messages, audio calls), built-in health and fitness trackers, having access to financial accounts through NFC (near-field-communication) technology payment cards, GPS functionality. All this information that was once considered “personal data” is now contained on these portable devices that are more susceptible to physical theft, man-in-the-middle attacks when connected to unsecure wireless and cellular networks, as well as potential exploitation of vulnerabilities that are typically present on a mobile device operating system.
The periodic release of security updates for mobile devices is an attestation to the fact that the operating system software that runs on your mobile devices are never 100% secure. Data that is stored and processed by mobile devices are at high risk of potential breaches, and therefore business organizations are not factored out of this threat.
Businesses across a wide array of industry verticals are shifting their technological landscape to adapt to a portable ecosystem, by introducing mobile devices. While the presence of mobile devices in a business environment grows, these devices are not being effectively secured through appropriate patch update cycles, and that unauthorized users may also be accessing these company-owned devices.
These mobile devices typically have access to substantial amounts of information and may also literally serve as the “keys to the kingdom” through serving as Multi-Factor Authentication (MFA) tokens to business information systems. An organization may have invested countless hours and resources to secure information technology infrastructure, but all that effort is now simply undermined by the fact that data is longer static within the confines of your organizations firewall perimeter.
Your data is now always on the move with your employees’ mobile devices. As a result, the need for an effective mobile device vulnerability management program is more imperative than ever, in order to consistently identify, track and remediate vulnerabilities, as a way to prevent the exploitation of vulnerabilities that may allow malicious users to gain access to your resources.
Mobile devices are not traditionally given a first thought when establishing a formal vulnerability management program. The devices that are typically given first thought include but are not limited to workstations, servers, networking appliances, web applications.
However, new threatening vulnerabilities are discovered and published daily in various vulnerability databases, and many of these discoveries specifically impact mobile devices. Mobile devices must not be overlooked when establishing your vulnerability program. A vulnerability scan can typically discover hundreds of vulnerabilities on your mobile devices, but all it takes to hand over the keys to your kingdom to a malicious actor is the exploitation of one of those vulnerabilities.
Organizations invest a significant amount of resources to secure their IT infrastructure, however these mobile devices now serve as an entry-point directly into the environment, providing access to potentially petabytes of your data. Despite these security concerns in mind, mobile device vulnerability management unfortunately remains an afterthought.
Without a formal vulnerability assessment for mobile devices, undetected vulnerabilities on these |

2022-08-17 10:00:00 | A pragmatic approach to risk management & resilience (lien direct) | Cybersecurity starts with the ability to recognize your cyber risk. We will explore several topics related to taking a practical approach to managing risk and achieving cyber resilience. This is a blog series with collective thoughts from Bindu Sundaresan, Director AT&T Cybersecurity, and Nick Simmons, AVP, Cybersecurity. Cybercrime has become increasingly frequent, complex, and costly, posing a risk to all businesses regardless of size. How do you plan to respond when falling victim to a breach? Would you know who to call, how to react, or what to tell your employees, customers, and media? Could your organization absorb the potential financial and reputational impact of a lawsuit? The answer cannot be, "we store everything in the cloud, so we are good." Who owns the risk? Could your brand's image survive? What is acceptable, and how do you know your current plan will suffice? What more could your company do to understand better and manage the risk? These questions are all top of mind and need to be addressed from an overall business perspective. This blog summarizes the fundamental steps and offers suggestions to understand, manage, and respond to risk. Beyond technology, focus on risk and resilience It can be easy to deploy security technology and think you've mitigated risk to your business. Unfortunately, technology investment is no guarantee of protection against the latest threats. It is critical to take a risk-based approach to security, meaning leaders must identify and focus on specific elements of cyber risk to decrease enterprise risk. Specifically, the many components of cyber risk must be understood and prioritized for enterprise cybersecurity efforts. Organizations are increasingly aiming to shift from cybersecurity to cyber resilience, and the following recommendations can help forge this path: Understand the threats Measure the potential financial impact of cyber exposures compared to the company's risk appetite level; and Proactively manage cyber risks with clear action plans based on their capabilities and capacities to protect against cybercrime Risk-based approach Cyber resiliency requires a risk-based approach, accomplishing two critical things at once. First, it designates risk reduction as the primary goal, enabling the organization to prioritize investment, including implementation-related problem solving based squarely on a cyber program's effectiveness at reducing risk. Second, the program distills top management's risk-reduction targets into pragmatic implementation programs with precise alignment from senior executives to the front line. Following the risk-based approach, a company will no longer "build the control everywhere"; rather, the focus will be on building the appropriate controls for the worst vulnerabilities to defeat the most significant threats that target the business' most critical areas. The risk-based approach to cybersecurity is thus ultimately interactive and a dynamic tool to support strategic decision-making. Focused on business value, utilizing a common language among the interested parties, and directly linking enterprise risks to controls, the approach helps translate executive decisions about risk reduction into control implementation. The power of the risk-based approach to optimize risk reduction at any level of investment is enhanced by its flexibility, adjusting to an evolving risk-appetite strategy as needed. A risk-based approach recognizes that there are no perfect security solutions. Still, those that strategically balance security, scalability, access, usability, and cost can ultimately provide the best long-term protection against an evolving adversary. Fundamentally, risk transformation changes security strategy from an outside-in perspective, where external threats and regulations drive strategy, to an | Ransomware Data Breach Tool Vulnerability Threat Patching Guideline | ||

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.

2022-08-16 10:03:51 | Vulnerability Spotlight: Three vulnerabilities in HDF5 file format could lead to remote code execution (lien direct) |  Dave McDaniel of Cisco Talos discovered these vulnerabilities. Blog by Jon Munshaw. Cisco Talos recently discovered three vulnerabilities in a library that works with the HDF5 file format that could allow an attacker to execute remote code on a targeted device. These issues arise in the libhdf5 gif2h5 tool that's normally used to convert a GIF file to the HDF5 format, commonly used to store large amounts of numerical data. An attacker could exploit these vulnerabilities by tricking a user into opening a specially crafted, malicious file. TALOS-2022-1485 (CVE-2022-25972) and TALOS-2022-1486 (CVE-2022-25942) are out-of-bounds write vulnerabilities in the gif2h5 tool that trigger a specific crash, opening the door for code execution from the adversary. TALOS-2022-1487 (CVE-2022-26061) works similarly but is a heap-based buffer overflow vulnerability. Cisco Talos is disclosing these vulnerabilities despite no official fix from HDF5 in adherence to the 90-day deadline outlined in Cisco's vulnerability disclosure policy.

Besides the usual security fixes, there was a zero-day of note:CVE-2022-34713: This is a vulnerability in Microsoft Support Diagnostic Tool (MSDT). Microsoft confirmed in their advisory that the vulnerability was exploited in the wild as a zero-day. CVE-2022-34713 is an arbitrary code execution (ACE) vulnerability, which requires user interaction. As such an user need to open a specifically crafted file or visit a specially designed Web site to be exploited. This has a CVSS score of 7.8 and is rated important.Why is this Significant?This is significant as Microsoft observed CVE-2022-34713 was exploited as a 0-day in the wild. Because the exploitation requires user interaction, an attacker likely uses social engineering to get users to open a specifically crafted file or visit a specially designed Web site for exploitation.How Widespread is the Attack that Leverages CVE-2022-34713?At this time, there is no information available as to how widespread the attack is. However, since the vulnerability was publicly disclosed, attacks that leverage CVE-2022-34713 may increase.Also, a similar vulnerability in MSDT (CVE-2022-30190, also known as Follina) that was patched in June 2022 by Microsoft is widely exploited in the wild.

2022-08-09 16:44:37 | Microsoft Patch Tuesday for August 2022 - Snort rules and prominent vulnerabilities (lien direct) |  By Jon Munshaw and Vanja Svajcer.Microsoft released its monthly security update Tuesday, disclosing more than 120 vulnerabilities across its line of products and software, the most in a single Patch Tuesday in four months. This batch of updates also includes a fix for a new vulnerability in the Microsoft Windows Support Diagnostic Tool (MSDT) that's actively being exploited in the wild, according to Microsoft. MSDT was already the target of the so-called “Follina” zero-day vulnerability in June. In all, August's Patch Tuesday includes 15 critical vulnerabilities and a single low- and moderate-severity issue. The remainder is classified as “important.” Two of the important vulnerabilities CVE-2022-35743 and CVE-2022-34713 are remote code execution vulnerabilities in MSDT. However, only CVE-2022-34713 has been exploited in the wild and Microsoft considers it “more likely” to be exploited. Microsoft Exchange Server contains two critical elevation of privilege vulnerabilities, CVE-2022-21980 and CVE-2022-24477. An attacker could exploit this vulnerability by tricking a target into visiting a malicious, attacker-hosted server or website. In addition to applying the patch released today, potentially affected users should enable Extended Protection on vulnerable versions of the server. The Windows Point-to-Point Tunneling Protocol is also vulnerable to three critical vulnerabilities. Two of them, CVE-2022-35744 and CVE-2022-30133, could allow an attacker to execute remote code on an RAS server machine. The other, CVE-2022-35747, could lead to a denial-of-service condition. CVE-2022-35744 has a CVSS severity score of 9.8 out of 10, one of the highest-rated vulnerabilities this month. An attacker could exploit these vulnerabilities by communicating via Port 1723. Affected users can render these issues unexploitable by blocking that port, though it runs the risk of disrupting other legitimate communications. Another critical code execution vulnerability, CVE-2022-35804, affects the SMB Client and Server and the way the protocol handles specific requests. An attacker could exploit this on the SMB Client by config |

So RapperBot, What Ya Bruting For?
(published: August 3, 2022)
RapperBot, a new Internet of things (IoT) botnet, is rapidly evolving despite appearing in the wild just two months ago (June 2022). Fortinet researchers discovered that RapperBot heavily reuses parts of the Mirai source code, but changed the attack vector (brute-forcing SSH instead of Telnet), command and control (C2) protocol, and added persistence capabilities. RapperBot maintains remote access by adding the attacker's public key to ~/.ssh/authorized_keys. The latest RapperBot samples also started adding the root user "suhelper” to /etc/passwd and /etc/shadow/, and continue to add the root user account every hour. Top targeted IPs were from Taiwan, USA, and South Korea, in that order. RapperBot has basic DDoS capabilities such as UDP and TCP STOMP flood copied from Mirai source code.
Analyst Comment: Despite sharing a significant amount of source code with Mirai variants, RapperBot appears to be developed by a persistent actor and not a novice motivated by notoriety. It is possible that the actors will add new impact functionality after the RapperBot botnet grows substantially. SSH server administrators should adhere to secure password practices. It is also important to note that simply restarting the device, changing SSH credentials or even disabling SSH password authentication does not remove the RapperBot infection.

The operators of the service also established Discord and Telegram communities where they provide technical support and assistance for customers on the platform.  Dark Utilities provides payloads consisting of code that is executed on victim systems, allowing them to be registered with the service and establish a command and control (C2) communications channel. The platform currently supports Windows, Linux and Python-based payloads, allowing adversaries to target multiple architectures without requiring significant development resources. During our analysis, we observed efforts underway to expand OS and system architecture support as the platform continues to see ongoing develo |
