A new downloader, which has been spotted in an array of recent email campaigns, uses anti-analysis techniques and calls in a system fingerprinting module.
A newly discovered downloader malware has been discovered as part of a new campaign primarily targeting financial institutions.
Researchers at Proofpoint said today that the downloader – dubbed “Marap” after its command-and-control phone-home parameter, “param,” spelled backwards – is notable for its focused functionality and modular nature, as well as its ability to perform reconnaissance through a systems-fingerprinting module.
“As defenses become more adept at catching commodity malware, threat actors and malware authors continue to explore new approaches to increase effectiveness and decrease the footprint and inherent ‘noisiness’ of the malware they distribute,” researchers said in Thursday’s
post about the new malware.
