Providing the source can help determine if it is a known phishing campaign or a specific forensic sample.

Only download wallet software from official domains (e.g., ledger.com , trezor.io ).

Do not extract the contents. Opening such files can trigger scripts that compromise your entire system .

While devices like COLDCARD do export backups as AES-encrypted .7z files , these are generated by the user on their own device and named specifically by the hardware—not downloaded as a "Cold Wallets All" package. Recommended Action Plan

If you have already interacted with the file, run a full system scan with reputable antivirus software and check for unauthorized background processes .

If you downloaded this file from an email, a social media link, or a non-official repository, it is likely a malicious package .

The filename is not an official release from any recognized hardware wallet manufacturer like Ledger , Trezor , or Tangem . Files with this naming convention—combining "all" with sensitive terms like "wallets"—are frequently associated with malware designed to steal private keys or phishing campaigns. Critical Security Assessment

If you suspect your computer is compromised, move any funds in "hot" (software) wallets to a new, clean environment immediately.
