NOTABLE RECENT SECURITY ISSUES

Title: NetWire RAT reappears with financial motivations
Description: Security researchers recently discovered a new variant of the NetWire remote access trojan being spread via fake business emails. Attackers are sending supposed invoices from legitimate-looking emails that download the RAT. Once infected, NetWire carries out a series of malicious actions that all appear aimed at stealing users’ financial information and logins. NetWire first emerged in 2012, and has since gone through various iterations across multiple adversaries.
