Description:
This IOC detects malware that abuses the debugger mechanism to get injected into a legit system process at startup. ThreatExpert uses this sentence with variable executable names: “so that [malware.exe] is injected into the execution sequence of [legit-system.exe] by being installed as its default debugger” A Google search for these terms (on ThreatExpert only) currently gives 2’240 hits (sample query: “site:threatexpert.com Image File Execution Options installs default debugger injected into the execution sequence”).
