PushEngage, OptinMonster, and TrustPulse CDN script-tampering campaign
Campaign
Summary
Hide ▲
Show ▼
A multi-plugin supply-chain campaign targeted Awesome Motive WordPress plugins OptinMonster, TrustPulse, and PushEngage, with malicious JavaScript delivered through the vendor’s CDN and triggered only when a WordPress administrator loaded an infected page. The code created rogue administrator accounts, installed a self-hiding backdoor plugin, and established follow-on access, putting up to 1.2 million websites at risk through the affected install base. Awesome Motive says attackers first reached a marketing server by exploiting a known UpdraftPlus flaw, stole the CDN API key, and then modified distributed JavaScript; the company has since rotated credentials and said its production systems were not breached.
