CISA and ENISA enhance their Cooperation

Image
  The European Union Agency for Cybersecurity (ENISA) has signed a Working Arrangement with the Cybersecurity and Infrastructure Security Agency (CISA) of the US, in the areas of capacity-building, best practices exchange and boosting situational awareness. Geopolitics have shaped the cyber threat landscape, bringing like-minded partners closer together in the wake of common cyber challenges and advances in digital technologies. Today at the EU-US Cyber Dialogue, ENISA and CISA announced the signing of their Working Arrangement as an important milestone in the overall cooperation between the United States and the European Union in the field of cybersecurity, also following the Joint Statement of European Commissioner Thierry Breton and U.S. Secretary for Homeland Security Alejandro Mayorkas of January 2023. ENISA’s International Strategy directs the Agency to be selective in engaging with international partners and to limit its overall approach in international cooperation to those...

SmartScreen Vulnerability: CVE-2024-21412 Facts and Fixes

Image
On Feb. 13, 2024, Microsoft issued a  patch  for CVE-2024-21412, a  Microsoft Defender SmartScreen  vulnerability revolving around internet shortcuts. Previously, we discovered that an advanced persistent threat (APT) group we track under the name Water Hydra has been exploiting CVE-2024-21412 in a sophisticated campaign targeting financial market traders, allowing the group to bypass Microsoft Defender SmartScreen and infect its victims with the DarkMe remote access trojan (RAT). Threat actors are constantly finding new ways of identifying and exploiting gaps to bypass security measures. We found that the bypass of CVE-2023-36025 (a previously patched SmartScreen vulnerability) led to the discovery and exploitation of CVE-2024-21412. This highlights how threat actors can circumvent patches by identifying new vectors of attack around a patched software component. It is important that organizations are able to identify and mitigate vulnerabilities, especiall...

Over 100 Malicious AI/ML Models Found on Hugging Face Platform

Image
As many as 100 malicious artificial intelligence (AI)/machine learning (ML) models have been discovered in the Hugging Face platform. These include instances where loading a  pickle file  leads to code execution, software supply chain security firm JFrog said. "The model's payload grants the attacker a shell on the compromised machine, enabling them to gain full control over victims' machines through what is commonly referred to as a 'backdoor,'" senior security researcher David Cohen  said . "This silent infiltration could potentially grant access to critical internal systems and pave the way for large-scale data breaches or even corporate espionage, impacting not just individual users but potentially entire organizations across the globe, all while leaving victims utterly unaware of their compromised state." Specifically, the rogue model initiates a reverse shell connection to 210.117.212[.]93, an IP address that belongs to the Korea Research Envir...
