7,500+ Magento sites defaced in global hacking campaign

Hackers defaced 7,500 Magento sites since Feb 27, uploading files across 15,000 hostnames, mostly opportunistic attacks.
Since February 27, a large-scale campaign has defaced over 7,500 Magento sites, targeting e-commerce platforms, global brands, and government services. According to cybersecurity firm Netcraft, attackers placed plaintext defacement files across more than 15,000 hostnames, directly compromising affected infrastructure.
“Netcraft detected this campaign’s first activity on 27 February 2026, with newly compromised sites continuing to appear at the time of writing.” reads the report published by Netcraft. “Netcraft is tracking this campaign’s activity over 15,000+ hostnames (subdomains) within ~7,500 unique domains. Defacements were uploaded as plaintext files hosted directly on affected infrastructure.”
Defacement pages show handles like L4663R666H05T, Simsimi, Brokenpipe, and Typical Idiot Security, often with “greetz” lists typical of defacement culture.
Most defaced sites hosted simple txt files showing attacker handles, often with “greetz” lists. A few (under 10) contained brief geopolitical messages on 7 March 2026, not central to the campaign. Many pages were reported to Zone-H by “Typical Idiot Security,” suggesting the actor self-reports to gain notoriety.
Initial investigation indicates attackers may exploit unauthenticated file uploads in some Magento environments, affecting Open Source, Enterprise, and B2B editions. Netcraft researchers observed only text defacements. While Adobe released security bulletins, these do not appear directly linked. The campaign resembles the October 2025 SessionReaper attack, with successful test uploads on Magento Community 2.4.9-beta1, highlighting Magento’s widespread global use.
The campaign hit…
