In early July 2024, the Sentinel Labs researchers released an extensive article1 about “FIN7 reboot” tooling, notably introducing “AvNeutralizer”, an anti-EDR tool. This tool has been found in the wild as a packed payload. In this article, we offer a thorough analysis of the associated private packer that we named “PackXOR”, as well as an unpacking tool. Additionally, while investigating the packer usage, we determined that PackXOR might not be exclusively leveraged by FIN7.

Russian Military Cyber Actors Target US and Global Critical Infrastructure
The Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), and National Security Agency (NSA) assess that cyber actors affiliated with the Russian General Staff Main Intelligence Directorate (GRU) 161st Specialist Training Center (Unit 29155) are responsible for computer network operations against global targets for the purposes of espionage, sabotage, and reputational harm since at least 2020. GRU Unit 29155 cyber actors began deploying the destructive WhisperGate malware against multiple Ukrainian victim organizations as early as January 13, 2022. These cyber actors are separate from other known and more established GRU-affiliated cyber groups, such as Unit 26165 and Unit 74455.
YubiKeys are vulnerable to cloning attacks thanks to newly discovered side channel
Sophisticated attack breaks security assurances of the most popular FIDO key. The YubiKey 5, the most widely used hardware token for two-factor authentication based on the FIDO standard, contains a cryptographic flaw that makes the finger-size device vulnerable to cloning when an attacker gains temporary physical access to it, researchers said Tuesday. The cryptographic flaw, known as a side channel, resides in a small microcontroller used in a large number of other authentication devices, including smartcards used in banking, electronic passports, and the accessing of secure areas. While the researchers have confirmed all YubiKey 5 series models can be cloned, they haven’t tested other devices using the microcontroller, such as the SLE78 made by Infineon and successor microcontrollers known as the Infineon Optiga Trust M and the Infineon Optiga TPM. The researchers suspect that any device using any of these three microcontrollers and the Infineon cryptographic library contains the same vulnerability.

Making progress on routing security: the new White House roadmap
On September 3, 2024, the White House published a report on Internet routing security. We’ll talk about what that means and how you can help. The Internet can feel like magic. When you load a webpage in your browser, many simultaneous requests for data fly back and forth to remote servers. Then, often in less than one second, a website appears. Many people know that DNS is used to look up a hostname, and resolve it to an IP address, but fewer understand how data flows from your home network to the network that controls the IP address of the web server.
In this blog post, BGP experts Doug Madory of Kentik and Job Snijders of Fastly review the latest RPKI ROV deployment metrics in light of a major milestone.
Transport for London faces 'ongoing cyber security incident'
Transport for London's (TfL) computer systems have been targeted in an ongoing cyber attack. It said there was no evidence customer data had been compromised and there was currently no impact on TfL services. Insiders have told BBC London they have been asked to work at home if possible, and that it is the transport provider's backroom systems at the corporate headquarters that are mainly affected.
Government Emails at Risk: Critical Cross-Site Scripting Vulnerability in Roundcube Webmail
Sonar’s Vulnerability Research Team recently discovered a critical Cross-Site Scripting (XSS) vulnerability in Roundcube, a popular open-source webmail software. When a victim views a malicious email in Roundcube sent by an attacker, the attacker can execute arbitrary JavaScript in the victim's browser. Attackers can abuse the vulnerability to steal emails, contacts, and the victim's email password as well as send emails from the victim's account. In October 2023, ESET Research reported that a similar vulnerability was actively used by the APT group Winter Vivern to attack European government entities. Roundcube administrators should update to the patched version 1.6.8 or 1.5.8 as soon as possible. * All discovered issues are tracked as CVE-2024-42008, CVE-2024-42009, CVE-2024-42010.

His targets include the FBI’s InfraGard portal, Airbus, credit reporting firm TransUnion, background checking service National Public Data (NPD), and many others.
Behind the arrest of Telegram boss, a small Paris cybercrime unit with big ambitions
Durov's arrest marks a shift in dealing with tech chiefs Brousse's unit goes after its biggest ever target Legal experts question the prosecution's argument The investigation into Telegram boss Pavel Durov that has fired a warning shot to global tech titans was started by a small cybercrime unit within the Paris prosecutor's office, led by 38-year-old Johanna Brousse. The arrest of Durov, 39, last Saturday marks a significant shift in how some global authorities may seek to deal with tech chiefs reluctant to police illegal content on their platforms. The arrest signalled the mettle of the J3 cybercrime unit, but the true test of its ambitions will be whether Brousse can secure a conviction based on a largely untested legal argument, lawyers said.
Après un ransomware, l'université Paris-Saclay lance un site provisoire
Comme d’autres services publics avant elle, l’université Paris-Saclay a subi une cyberattaque par le biais d’un ransomware sur ses serveurs. L’attaque qui a eu lieu le 11 août a affecté les services centraux de l’établissement, ainsi que ses composantes (facultés, IUT, Polytech Paris-Saclay, Observatoire des sciences de l’univers). Sont notamment indisponibles un certain nombre de services comme la messagerie électronique, l’intranet, les espaces partagés et certaines applications métier. Un site provisoire a été mis en ligne afin d’assurer, durant les prochaines semaines, la communication auprès des personnels et des étudiants. Une foire aux questions, relative à la cyberattaque, régulièrement complétée et actualisée y est affichée.

The Dirty Pipe Vulnerability — The Dirty Pipe Vulnerability documentation
This is the story of CVE-2022-0847, a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes. It is similar to CVE-2016-5195 “Dirty Cow” but is easier to exploit. The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.
Cybercriminals operating ransomware as a service from overseas continue to be responsible for most high-profile cybercrime attacks against the UK
The deployment of ransomware remains the greatest serious and organised cybercrime threat, the largest cybersecurity threat, and also poses a risk to the UK’s national security. Ransomware attacks can have a significant impact on victims due to financial, data, and service losses, which can lead to business closure, inaccessible public services, and compromised customer data. Threat actors are typically based in overseas jurisdictions where limited cooperation makes it challenging for UK law enforcement to disrupt their activities.
