A phishing campaign impersonates DocuSign to trick victims into installing legitimate remote management software such as MeshAgent, ScreenConnect, and SimpleHelp. It uses a reusable web kit with staged delivery, user-agent filtering targeting Windows systems (excluding Edge browsers), and Cloudflare Turnstile verification. The campaign features separate delivery paths for Windows and macOS, disables Windows Defender via VBS scripts, and establishes persistence through service installation. Active from May to July 2026, it rotates infrastructure across multiple domains to evade detection while abusing trusted IT tools for persistent access.

A ClickFix campaign has been identified that abuses Anthropic's Claude platform through shareable chat links to distribute MacSync Stealer targeting macOS users. Attackers utilized malvertising with paid Google ads to direct victims searching for Claude-related terms to malicious shared Claude chats falsely labeled as 'Apple Support.' These chats contained obfuscated installation commands that, when executed, deployed a multi-stage infection chain. The malware steals credentials from browsers and password managers, cryptocurrency wallet data, sensitive files, and system information. The campaign ran from June 12-19, 2026, targeting primarily Mac users with Russian-language comments in the code suggesting Russian-speaking threat actors. Domains used adopted themes related to U.S. local services to appear legitimate.

During June 2026, multiple infostealer families including Remus, ACRStealer, LummaC2, and Vidar were distributed through SEO poisoning techniques, disguised as illegal software such as cracks and keygens. Attacks utilized EXE files (84.5%) and DLL side-loading (15.5%) methods, with distribution primarily through Mediafire, Mega, and cloud storage platforms. Microsoft Corporation was the most frequently impersonated entity. MacOS environments were targeted through ClickFix techniques and malicious Bash scripts, with one variant dynamically obtaining C2 addresses via Polygon smart contracts. Email-based campaigns distributed AgentTesla and DarkCloud through compressed attachments, with both variants exfiltrating data via SMTP. The stolen credentials pose significant risks for dark web trading and secondary attacks.
