Hackers Poison Adform Script to Swap Crypto Wallet Addresses Across Customer Sites
Matched: cryptocurrency
Attackers modified a JavaScript file from ad tech firm Adform to silently replace cryptocurrency wallet addresses in users' browsers. The malicious script, active on July 27, 2026, targeted Bitcoin and other crypto addresses copied by visitors to affected sites. Adform detected and removed the code the same day, notified clients, and reported the incident to authorities. Users who transacted on July 27 should verify their wallet addresses.
