A remote access Trojan (RAT) dubbed InnfiRAT comes with extensive capabilities to steal sensitive information, including cryptocurrency wallet data. Zscaler’s ThreatLabZ team took a closer look at its inner workings, although the malware has been in the wild for a while.
The earliest this RAT was spotted is November 2017, according to security researcher James_inthe_box, but this is the first time it was analyzed more seriously.
