A DLL side-loading vulnerability (CVE-2026-110936) in Siemens Software Center version 3.5.8.7 is actively exploited by attackers distributing a genuine signed application with malicious DLLs via unofficial channels. The vulnerable software loads attacker-supplied DLLs without validation, enabling code execution. The attack uses ClickFix social engineering to trick users into running commands. Version 4.0.9.8 patches the vulnerability with automatic updates applied on restart. No official Siemens systems or distribution channels were compromised during this campaign.
A compromised EmEditor installer was used in a software supply chain attack to deliver multistage malware. The attack, discovered in late December 2025, targeted users of this widely-used text editor. The malware performs credential theft, data exfiltration, and enables lateral movement. It uses obfuscated PowerShell scripts and geofencing techniques, suggesting possible Russian origin. The malware disables security features, gathers system information, and exfiltrates data to a command-and-control server. This incident highlights the importance of validating installer integrity, monitoring PowerShell usage, preserving endpoint telemetry, and enforcing least privilege principles. Software publishers are advised to secure download infrastructure and prepare incident response plans.
PurpleBravo, a North Korean state-sponsored threat group, targets software developers through fake recruitment efforts, particularly in cryptocurrency and software development sectors. Their toolkit includes BeaverTail, PyLangGhost, and GolangGhost, designed for stealing browser credentials and cryptocurrency information. The group has affected 3,136 IP addresses, mainly in South Asia and North America, compromising 20 organizations across various industries. PurpleBravo's tactics include using fictitious personas, malicious GitHub repositories, and sophisticated malware to infiltrate IT services companies, posing a significant supply-chain risk. The group shows overlap with PurpleDelta, another North Korean threat actor, sharing infrastructure and operational patterns. PurpleBravo's focus on the IT sector in South Asia presents an overlooked threat to organizations outsourcing IT services.
A loophole in VS Code Marketplace allows malicious actors to reuse names of removed extensions. ReversingLabs discovered this vulnerability after finding a malicious extension with the same name as one previously identified. The platform's documentation states that extension names must be unique, but removed extensions' names can be reused. This poses a risk of threat actors publishing malicious extensions under previously legitimate names. The research team conducted experiments to confirm this vulnerability, successfully publishing extensions with names of removed packages. This technique has been observed in other open-source platforms like PyPI. The discovery highlights the increasing popularity of VS Code Marketplace among malicious actors and the need for developers to be vigilant about package security.
