Background for this topic.
Bypass describes attacker methods that circumvent specific security controls, such as authentication checks, input validation, or detection systems, without directly exploiting the underlying vulnerability. These techniques often leverage design flaws, misconfigurations, or protocol weaknesses to evade protections like firewalls, multi-factor authentication, or antivirus scanning.
Bypassing controls can enable unauthorized access, data exfiltration, or persistent presence while avoiding alerts, complicating detection and response. Effective defense requires layered security measures, rigorous configuration management, and continuous validation of control effectiveness to identify and close bypass paths before attackers exploit them.
Attackers use Google redirects in their phishing attack leveraging a now-patched vulnerability that spreads the multifaceted malware.
A DarkGate malware campaign observed in mid-January 2024 leveraged a recently patched security flaw in Microsoft Windows as a zero-day using bogus software installers
