Rewterz Threat Alert – NetWire RAT Malware – Active IOCs

Severity

High

Analysis Summary

NetWire is a remote access tool and a malicious program (RAT). RATs are often used to remotely access and manipulate computers. These programs can be used for lawful purposes by system administrators to get access to client systems, but they can also be used for malicious purposes. NetWire is a keylogger used by cybercriminals to collect data from USB card readers and other peripheral devices. This sends emails containing potentially dangerous files. The malware gets downloaded into the victim’s machine after the victim clicks on it. Crooks frequently use PDF, Word, and IMG files as shared files for their malware payloads.
