The COM Hijacking technique is often utilized by threat actors and various malware families to achieve both persistence and privilege escalation in target systems. It relies on manipulating Component Object Model (COM), exploiting the core architecture of Windows that enables communication between software components, by adding a new value on a specific registry key related…

The MITRE framework helps all defenders speak the same language regarding attackers’ modus operandi. VirusTotal provides multiple data points where MITRE’s Tactics and Techniques are dynamically extracted from samples when detonated in our sandboxes. In particular, samples’ MITRE mapping can be found under the BEHAVIOR tab of a file’s report. This data is searchable in…

TLDR: VT Crowdsourced Sigma rules will now also match suspicious activity for macOS and Linux binaries, in addition to Windows. We recently discussed how to maximize the value of Sigma rules by easily converting them to YARA Livehunts. Unfortunately, at that time Sigma rules were only matched against Windows binaries. Since then, our engineering team…
