SonicWall is warning customers that the recently patched critical vulnerability CVE-2024-40766 may be exploited in the wild.
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.
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.
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.
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.
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.
