VPNs are a vital part of the security infrastructure but they can be vulnerable or hackable and can be weaponized against you. Security experts have uncovered a new phishing campaign that attempts to trick Microsoft Office 365 users with fake VPN configuration update requests. The purpose of the campaign is to steal login credentials from users. In a different incident, three fake iOS VPN apps - Beetle VPN, Buckler VPN, and Hat VPN Pro - duped users with high subscription charges without providing the services they claimed.
Cyberespionage campaigns wherein attackers used different obfuscation techniques to target organizations also came to notice in the last 24 hours. While the Ursnif trojan used Excel 4.0 macro to spread laterally across networks, the Metamorfo banking trojan leveraged the DLL hijacking technique to conceal its presence on targeted systems.
