Summary from the TLDR InfoSec newsletter

The 2025 macOS threat landscape was characterized by a surge in sophisticated infostealers and state-sponsored backdoors that increasingly leverage "Malware-as-a-Service" models and social engineering vectors such as "ClickFix" and fake job interviews. Technical analysis reveals that attackers are bypassing Gatekeeper and static analysis by utilizing signed or notarized binaries and executing multi-stage payloads written in Go, Python, and AppleScript directly in memory. To combat these evolving threats, security professionals must move beyond static signatures to implement behavioral monitoring of process, file, and network activity while educating users on the dangers of executing terminal commands from untrusted sources.
