ShadowPad Malware – Modular Backdoor Threat

ShadowPad is a sophisticated modular backdoor malware that first emerged in 2017 during a supply chain attack involving NetSarang software. Initially linked to the Chinese cyber-espionage group APT41, it has since been adopted by multiple Chinese threat actors. Designed to infiltrate systems by embedding itself into legitimate software, ShadowPad maintains persistent access and control over compromised devices. Its modular architecture allows dynamic deployment of additional malicious payloads, enabling activities like data exfiltration and system manipulation. Organizations must implement robust cybersecurity measures, including regular software updates and vigilant network monitoring, to defend against ShadowPad infections.​

SparrowDoor Backdoor Variants Target US and Mexico

New SparrowDoor Backdoor Variants Found in Attacks on U.S. and Mexican Organizations

Ravi Jain
Cybersecurity researchers have identified two new, more sophisticated variants of the SparrowDoor backdoor used by the China-linked threat group FamousSparrow. These updated malware versions, discovered during July 2024 attacks on organizations in the U.S. and Mexico, feature enhanced capabilities like modularity and parallel command execution, alongside improved anti-detection techniques. This campaign also marked the first observed use of the ShadowPad malware by FamousSparrow, a tool commonly associated with other Chinese APT actors, suggesting potential resource sharing. The attacks exploited vulnerabilities in outdated Microsoft systems to deploy these backdoors, enabling persistent access, command execution, and data theft. Organizations are urged to update systems and implement advanced security measures to defend against this evolving threat. ... Read More
