The Detection & Response Chronicles: Covert Operations Through QEMU

Adversaries have always relied on legitimate tools to carry out their attacks. These tools are already trusted by security solutions, which allows them to blend in with normal activity, maintain a low footprint, and make detection much harder for defenders. By using these legitimate tools, adversaries can carry out a wide range of actions, such as moving laterally across networks, establishing C2 channels, or maintaining persistence, all without triggering any alerts.

The Axios npm supply chain incident: fake dependency, real backdoor

On March 31, 2026, two malicious Axios versions (1.14.1 and 0.30.4) were briefly published to npm via a compromised maintainer account. The only change performed was the addition of a trojanized dependency, whose postinstall script deployed a cross‑platform RAT (for macOS, Windows, and Linux). Although the Axios packages were removed within hours, multiple hits were … Continue reading The Axios npm supply chain incident: fake dependency, real backdoor →

Scaling your threat hunting operations with CrowdStrike and PSFalcon

Introduction Most modern day EDRs have some sort of feature which allows blue teamers to remotely connect to hosts with an EDR agent/sensor installed, to aid in their investigation of incidents. In CrowdStrike, this is called Real Time Response, and it provides a wide range of capabilities, from executing built-in commands like ipconfig and netstat … Continue reading Scaling your threat hunting operations with CrowdStrike and PSFalcon →

Detecting BCD Changes To Inhibit System Recovery

Introduction Earlier this year, we observed a rise in malware that inhibits system recovery. This tactic is mostly used by ransomware and wiper malware. One notable example of such malware is “Hermetic wiper”. To inhibit recovery an attacker has many possibilities, one of which is changing the Boot Configuration Database (BCD). This post will dive … Continue reading Detecting BCD Changes To Inhibit System Recovery →
