Raymond Leong, Dan Perez, and Tyler Dean report:

FireEye Mandiant recently discovered a new malware family used by APT41 (a Chinese APT group) that is designed to monitor and save SMS traffic from specific phone numbers, IMSI numbers and keywords for subsequent theft. Named MESSAGETAP, the tool was deployed by APT41 in a telecommunications network provider in support of Chinese espionage efforts. APT41’s operations have included state-sponsored cyber espionage missions as well as financially-motivated intrusions. These operations have spanned from as early as 2012 to the present day. For an overview of APT41, see our August 2019 blog post or our full published report. MESSAGETAP was first reported to FireEye Threat Intelligence subscribers in August 2019 and initially discussed publicly in an APT41 presentation at FireEye Cyber Defense Summit 2019.
