Researchers have discovered a malicious campaign utilizing a never-before-seen technique for quietly planting fileless malware on target machines.
The technique involves injecting shellcode directly into Windows event logs. This allows adversaries to use the Windows event logs as a cover for malicious late stage trojans, according to a Kaspersky research report released Wednesday.
Researchers uncovered the campaign in February and believe the unidentified adversaries have been active for the past month.
