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 →

DeTT&CT : Mapping detection to MITRE ATT&CK

Introduction Building detection is a complex task, especially with a constantly increasing amount of data sources. Keeping track of these data sources and their appropriate detection rules or avoiding duplicate detection rules covering the same techniques can give a hard time to detection engineers. For a SOC, it is crucial to have an good overview … Continue reading DeTT&CT : Mapping detection to MITRE ATT&CK →
