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.
Cybersecurity researchers have detailed a new adversary-in-the-middle (AitM) phishing kit that's capable of Microsoft 365 accounts with an aim to steal credentials and two-factor authentication (2FA) codes since at least October 2024
Attackers Can Employ a Vulnerable Driver to Target Most Windows and Linux SystemsResearchers are warning Microsoft Windows as well as many Linux distribution users to install updates that revoke permissions for a vulnerable driver that attackers can use to target most systems, allowing them to bypass UEFI Secure Boot and install a bootkit to take full control of a system.
A new UEFI Secure Boot bypass vulnerability tracked as CVE-2024-7344 that affects a Microsoft-signed application could be exploited to deploy bootkits even if Secure Boot protection is active. [...]
Details have emerged about a now-patched security vulnerability that could allow a bypass of the Secure Boot mechanism in Unified Extensible Firmware Interface (UEFI) systems
HP Wolf highlighted novel techniques used by attackers to bypass email protections, including embedding malicious code inside images and utilizing GenAI
A newly discovered botnet of 13,000 MikroTik devices uses a misconfiguration in domain name server records to bypass email protections and deliver malware by spoofing roughly 20,000 web domains. [...]
Microsoft kicked off 2025 with a new set of patches for a total of 161 security vulnerabilities across its software portfolio, including three zero-days that have been actively exploited in attacks
Emergent macOS vulnerability lets adversaries circumvent Apple's System Integrity Protection (SIP) by loading third-party kernels.
Microsoft Uncovered Flaw That Affects macOS System Integrity Protection FeatureApple patched a vulnerability that allows hackers to bypass a key security feature in macOS by through third-party kernel extensions. Microsoft researchers uncovered the flaw tracked as CVE-2024-44243. The flaw could enable hackers to install rootkits and create malware with privileged access.
Microsoft has shed light on a now-patched security flaw impacting Apple macOS that, if successfully exploited, could have allowed an attacker running as "root" to bypass the operating system's System Integrity Protection (SIP) and install malicious kernel drivers by loading third-party kernel extensions
Attackers are exploiting a new authentication bypass zero-day vulnerability in FortiOS and FortiProxy to hijack Fortinet firewalls and breach enterprise networks. [...]
Scumbags stole API keys, then started a hacking-as-a-service biz, it is claimed Microsoft has sued a group of unnamed cybercriminals who developed tools to bypass safety guardrails in its generative AI tools. The tools were used to create harmful content, and access to the tools were sold as a service to other miscreants.…
Apple recently addressed a macOS vulnerability that allows attackers to bypass System Integrity Protection (SIP) and install malicious kernel drivers by loading third-party kernel extensions. [...]
