SideWinder, aka T-APT-04 or RattleSnake, is one of the most prolific APT groups that began its activities in 2012 and was first publicly mentioned by us in 2018. Over the years, the group has launched attacks against high-profile entities in South and Southeast Asia. Its primary targets have been military and government entities in Pakistan, Sri Lanka, China and Nepal.
Over the years, SideWinder has carried out an impressive number of attacks and its activities have been extensively described in various analyses and reports published by different researchers and vendors, one of the latest of which was released at the end of July 2024. The group may be perceived as a low-skilled actor due to the use of public exploits, malicious LNK files and scripts as infection vectors, and the use of public RATs, but their true capabilities only become apparent when you carefully examine the details of their operations.
