Cybercriminals are impersonating Anthropic’s Claude app to steal cryptocurrency, according to new research. The scheme appears to capitalize on heightened interest in Anthropic’s latest model releases, with scammers luring users by promising “free” access to premium capabilities.
Impersonation Campaign Targets Crypto Holders
Researchers warn that threat actors are launching fake Claude-branded downloads and websites designed to compromise users’ devices and drain bitcoin and other crypto wallets. These campaigns commonly use search ads, social media posts, and phishing emails to drive victims to counterfeit portals that mimic legitimate AI download pages.
The scams reportedly reference Anthropic’s recently released Fable 5.1 and Mythos 5.1 models to entice users seeking advanced features. Once a victim installs the bogus app or browser extension, malware can capture sensitive data or trigger wallet-draining actions.
Researchers Flag Fake ‘Claude Opus’ Lures
Cybersecurity firm Morphisec reported discovering a fraudulent distribution that purports to offer a “Claude Opus 5” download. The spoofed branding is used to build credibility and convince users to install malicious software. Morphisec’s findings indicate the operation specifically targets holders of digital assets, aiming to exfiltrate private keys, seed phrases, and other credentials associated with crypto wallets.
How to Protect Your Funds
- Download software only from official company domains and verified app stores; avoid third-party installers and links shared in ads or unsolicited messages.
- Never enter wallet seed phrases, private keys, or API keys into unverified apps, pop-ups, or browser extensions.
- Use hardware wallets and enable multi-factor authentication where possible.
- Keep operating systems, browsers, and security tools updated; scan downloads before opening.
- Check URLs carefully for typosquatting and look for verified publisher information before installing extensions.
Why It Matters
Brand impersonation remains a persistent tactic in financially motivated cybercrime, and demand for powerful AI tools provides a timely hook for threat actors. Crypto users seeking the latest AI capabilities are being singled out with realistic spoofing and malware delivery techniques. Exercising strict download hygiene and verifying sources can significantly reduce the risk of wallet theft.
