Threat actors are exploiting the OpenClaw AI agent ecosystem by publishing malicious skills on the ClawHub marketplace. These skills leverage semantic instruction hijacking to bypass traditional security controls, delivering macOS infostealers via base64-encoded droppers, utilizing massive file padding for defense evasion, and executing novel agentic financial fraud schemes like runtime affiliate injection and front-running.
Threat actors are increasingly targeting macOS environments with infostealers delivered via deceptive .dmg disk images. These attacks rely on social engineering tactics, such as custom background images and misleading filenames, to trick users into bypassing Apple's Gatekeeper protections. This enables rapid 'smash-and-grab' data theft without the need for the malware to establish persistence on the host.
Kaspersky's Q1 2026 threat report highlights significant law enforcement actions against major ransomware operators, alongside the emergence of new ransomware groups like The Gentlemen. The quarter also saw active zero-day exploitation of Cisco Secure FMC (CVE-2026-20131) by the Interlock group, a rise in macOS-targeted crypto stealers and supply chain attacks via the Axios npm package, and persistent IoT botnet activity dominated by Mirai variants.
Sophos MDR investigated a macOS infostealer infection attributed to an AMOS (Atomic macOS) variant. The attack leverages ClickFix social engineering to trick users into running a malicious Terminal command, which initiates a multi-stage infection chain. The malware captures the user's system password via a spoofed prompt, evades analysis by checking for virtualized environments, and exfiltrates sensitive data like Keychain and browser credentials before establishing persistence via a LaunchDaemon.
The article highlights the evolution of social engineering tactics, emphasizing how attackers abuse trusted workflows, AI platforms, and legitimate infrastructure like OAuth to bypass traditional security controls. Key threats include device code phishing campaigns like EvilTokens that bypass MFA for persistent access, and AI chatbot lures tricking macOS users into executing AMOS infostealer payloads via malicious terminal commands.
