Security experts are trying to solve a mysterious espionage campaign that went undetected for more than six months. The targeted victims included organizations in defense, healthcare, and ICT sectors across Southeast Asia and the toolset involved a modular backdoor, a keylogger, and an exfiltration tool. However, it is not yet clear which threat actor group was behind this attack.

The hackers harvested mobile network data from at least 13 telecom companies in the past two years. Meanwhile, researchers added one more malware to the growing list of ransomware families. Dubbed Karma, a relatively new ransomware shares similarities with Nemty variants.
