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.

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Cisco urging users to update Firepower Management Center immediately to fix severe bug
Description: Cisco disclosed a high-severity vulnerability in its Firepower Management Center last week that could allow an attacker to bypass the usual authentication steps. The vulnerability — which was assigned a 9.8 severity score out of 10 — exists in the way Firepower handles LDAP authentication responses from an external authentication server. An attacker could exploit this flaw by sending a specially crafted HTTP request to the device. Users are also encouraged to turn off LDAP configuration on their devices. Cisco also disclosed seven high-severity flaws and 19 medium-severity security issues in some of its other products, including Smart Software Manager.
