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.
The UEFI firmware implementation in some motherboards from ASUS, Gigabyte, MSI, and ASRock is vulnerable to direct memory access (DMA) attacks that can bypass early-boot memory protections. [...]
Internet security watchdog Shadowserver has found over 25,000 Fortinet devices exposed online with FortiCloud SSO enabled, amid ongoing attacks targeting a critical authentication bypass vulnerability. [...]
Experts Say AI Is Already Enabling Faster and Harder-to-Detect Attack CampaignsArtificial intelligence-fueled malware and automated cyber tools are enabling faster, more adaptive attacks at scale, with experts warning Congress that adversaries are now leveraging AI and quantum advances to outpace defenders and bypass outdated security architectures.
