Project TajMahal – a sophisticated new APT framework


TajMahal’ is a previously unknown and technically sophisticated APT framework discovered by Kaspersky Lab in the autumn of 2018. This full-blown spying framework consists of two packages named ‘Tokyo’ and ‘Yokohama’. It 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. We discovered up to 80 malicious modules stored in its encrypted Virtual File System, one of the highest numbers of plugins we’ve ever seen for an APT toolset.

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.

TajMahal has been developed and used for at least the past five years. The first known ‘legit’ sample timestamp is from August 2013, and the last one is from April 2018. The first confirmed date when TajMahal samples were seen on a victim’s machine is August 2014.
