Detection of processes loading Mozilla NSS/Mozglue libraries (mozglue.dll, nss3.dll) outside of known Mozilla applications, potentially indicating malware or unauthorized activity.

Attackers may attempt to evade defenses by masquerading malicious processes as legitimate communication applications such as Slack, WebEx, Teams, Discord, RocketChat, Mattermost, WhatsApp, Zoom, Outlook and Thunderbird.

Attackers masquerade malicious executables as legitimate business application installers to trick users into downloading and executing malware, leveraging defense evasion and initial access techniques.
