North Korea Buried Four-Stage Malware in Flag Images: Zero Antivirus Detections

North Korea's Contagious Interview hackers have been using a deceptive strategy to target developers by posing as recruiters and embedding malware in SVG files. Elastic Security Labs discovered that the attackers hid malicious payloads within HTML comment blocks of these files, allowing the malware to evade antivirus detection. At the time of the findings, no antivirus engines flagged the compromised repositories, which included trojanized GitHub repositories disguised as coding challenges. The malware executed automatically at server startup and deployed four modules: a browser credential and cryptocurrency wallet stealer, a file stealer, a remote access Trojan, and a clipboard monitor. The campaign, tracked as REF9403, is part of the ongoing Contagious Interview operation attributed to North Korea's Lazarus Group, which aims to generate revenue through cryptocurrency theft. Developers are advised to audit any projects run from unsolicited sources and to monitor specific domains associated with the attack.

New GreatXML Exploit Bypasses Windows BitLocker via Recovery Partition XML Files

Security researcher Chaotic Eclipse has released a Windows BitLocker bypass tool named GreatXML, following a previously disclosed exploit targeting Microsoft Defender. The discovery was made accidentally and took four hours. A critical vulnerability exists for users who have used the Windows Defender Offline Scan feature, making them susceptible to the BitLocker bypass. The exploit involves copying an XML file and a recovery folder to the recovery partition and rebooting into the Windows Recovery Environment (WinRE). If the Defender offline scan was not initiated, users must log in to start it or find a way to boot into WinRE in offline scan state. GreatXML is the second BitLocker bypass tool released by Chaotic Eclipse, following the earlier exploit known as YellowKey (CVE-2026-45585), which has been patched by Microsoft.

CVE-2024-55638: Highly Critical Drupal Core Vulnerability Threatens PostgreSQL Sites with Remote Code Execution (RCE)

A critical vulnerability, CVE-2024-55638, has been identified in Drupal Core, affecting installations using PostgreSQL as their backend database. This vulnerability involves PHP Object Injection, which can lead to full Remote Code Execution (RCE) when combined with another deserialization flaw. It cannot be exploited independently but increases the risk for Drupal installations that use third-party modules or custom code that improperly employs the unserialize() function. The affected versions include Drupal Core 7.x prior to 7.102, 8.0.0 and above prior to 10.2.11, and 10.3.0 prior to 10.3.9, with patched versions being 7.102, 10.2.11, and 10.3.9. The vulnerability is particularly relevant for sites using PostgreSQL, and organizations are urged to upgrade to the patched versions and audit their code for unsafe unserialize() usage. Currently, there are no confirmed reports of exploitation in the wild, but the risk remains high due to insecure deserialization bugs in third-party modules. The EPSS score for this vulnerability is 9.93%, indicating a significant likelihood of exploitation in the near future.
