Embedded Malicious Code
Overview Affected versions of this package are vulnerable to Embedded Malicious Code that hides inside binary executable files triggered by a postinstall script. IronWorm is a sophisticated, Rust-based infostealer that functions as a self-replicating supply-chain attack. Its primary characteristi...
⚡ Weekly Recap: Linux Rootkit, macOS Crypto Stealer, WebSocket Skimmers and More
Rough Monday. Somebody poisoned a trusted download again, somebody else turned cloud servers into public housing, and a few crews are still getting into boxes with bugs that should’ve died years ago — the same old holes, same lazy access paths, same “how the hell is this still open” feeling. One...

Quasar Linux (QLNX) – A Silent Foothold in the Supply Chain: Inside a Full-Featured Linux RAT With Rootkit, PAM Backdoor, Credential Harvesting Capabilities
TrendAI™ Research breaks down Quasar Linux QLNX, a previously undocumented sophisticated Linux RAT with low detection rates. In this blog, we examine a full-featured Linux threat incorporating a rootkit, a PAM backdoor, credential harvesting, and more, revealing how this malware enables stealthy...
SeqShield: A Behavioral Analysis Approach to Uncover Rootkits
Rootkits are among the most elusive types of malware, capable of bypassing traditional static analysis methods due to their metamorphic behavior. Signature-based detection techniques struggle against these threats, necessitating a shift toward dynamic analysis approaches. We propose SeqShield, a...
