Initial access was immediately followed by attempts to dump credentials and establish persistent backdoors. Key Technological Vectors Exploited In February alone

Several critical flaws disclosed during this period involved remote code execution (RCE) and authentication bypasses. Attackers bypassed multi-factor authentication (MFA) protocols by targeting the underlying logical flaws in gateway software, allowing them to gain administrative access without valid credentials.
