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.
BlackLotus is the first in-the-wild malware to exploit a vulnerability in the Secure Boot process on Windows, and experts expect copycats and imminent increased activity.
Attackers use phishing emails that appear to come from reputable organizations, dropping the payload using public cloud servers and an old Windows UAC bypass technique.
