New Highly Advanced APT Malware Framework TajMahal that Goes Undetected for 5 years

Security researchers at Kaspersky uncovered a new highly sophisticated APT malware Framework dubbed TajMahal which includes a number of malicious modules capable of performing various attacks.

The operation has gone undetected for the last five years, the timestamp of the first sample is from August 2013 and the last one is April 2018. It contains 80 malicious modules in its encrypted Virtual File System.

Based on Kaspersky telemetry only a single victim to date identified infected with the APT Malware Framework .

“Just to highlight its capabilities, TajMahal is able to steal data from a CD burnt by a victim as well as from the printer queue. It can also request to steal a particular file from a previously seen USB stick; next time the USB is connected to the computer, the file will be stolen.”

The APT platform contains two packages Tokyo and Yokohama, one acts the first stage of infection and the next one delivers the malware.

The package ” includes backdoors, loaders, orchestrators, C2 communicators, audio recorders, keyloggers, screen and webcam grabbers, documents and cryptography key stealers, and even its own file indexer for the victim’s machine,” reads SecureList blog post.

Second-stage payload Yokohama accumulates malicious modules in a virtual file system that allows malware to perform the following functions

• Stealing browser cookies
• Intercepting documents from the print queue
• Recording and taking screenshots of VoIP calls,
• Stealing optical disc images made by the victim,
• Collecting data about the victim
• Indexing files, including those on external drives, and potentially stealing specific files when the drive is detected again.

The technical complexity of TajMahal makes it a very worrying discovery, and the number of victims identified thus far is likely to increase, Kaspersky said.
