A family member installed “SamFW Tool” from samfw.com on Jun 23, 2026. Shortly after installation, 10,000 XMR (about $3 million) were withdrawn from the Feather Wallet, and everything in victim’s computer data was deleted.
After installing samfwtoolsetup_v5.4.zip, the scammer tungtata stole the funds from the Feather Wallet. After the theft, they removed and modified the original tool package to reduce evidence. The download is now replaced with a revised version labeled SamFwToolSetup_v5.5.1.zip.
