Malcious Admin Menu Editor Pro plugin backdoors 1,500 WordPress sites

Compromised Admin Menu Editor Pro update server distributed backdoored plugin versions installing web shells and hidden admin accounts on roughly 1,500 WordPress sites.

A threat actor with root-level access to adminmenueditor.com pushed trojanized Admin Menu Editor Pro versions 2.35 and 2.36 containing includes/wp-user-consent.php, which installed a web shell and created a hidden wp_-prefixed user account. At least 230 customers and roughly 1,500 sites installed the malicious update, with several hundred more downloads possibly affected. Developer Janis Elsts took the site offline after the attacker recompromised the clean 2.36 release; version 2.34 and the free plugin are believed unaffected.

Brevo supply chain attack hits 100k+ sites with Wordpress backdoors and Clickfix malware

Attackers with Brevo DNS access injected malicious scripts serving ClickFix malware and WordPress backdoors to over 100,000 customer sites on 14 September 2026.

Brevo (formerly Sendinblue), an email marketing platform whose clients include eBay, Louis Vuitton, Michelin and Amnesty International, served injected JavaScript from sendibt1.com domains between 16:05 and 20:12 UTC on 14 September 2026, reaching over 100,000 customer sites and mailing lists. The f.js malware secretly installed a WordPress backdoor plugin from cdn10.sendibt1.com/p/wm.zip using logged-in admins' sessions and showed ClickFix overlays urging visitors to copy-paste and run commands. An SSL certificate for cdn.sendibt1.com created August 25 and attacker-created cdn* DNS records indicate write access to Brevo's Cloudflare DNS, likely via a single Cloudflare account compromise. Sansec recorded 2,549 CSP violation reports across 12 monitored sites; all malicious hosts stopped resolving on 15 September and Brevo's status page lists no incident.

Muhstik Botnet Attacks Tomato Routers to Harvest New IoT Devices

Unit 42 found a Muhstik botnet variant brute-forcing Tomato router web authentication to harvest IoT devices for crypto mining and DDoS attacks.

Palo Alto Networks Unit 42 researchers in December 2019 identified a new Muhstik botnet variant scanning Tomato routers on TCP 8080 and brute-forcing default admin credentials, targeting roughly 4,600 exposed devices found via Shodan. The variant also scans WordPress and Webuzo installations and exploits the Oracle WebLogic deserialization flaw CVE-2019-2725 for unauthenticated remote code execution. Muhstik, active since March 2018, self-propagates like a worm and typically monetizes infections through cryptocurrency mining and DDoS attacks controlled via an IRC C2 channel.

Hackers Turn More Than 3,500 Redis Servers Into Cryptocurrency Miners

Hunters.io researchers report 3,562 exposed Redis servers hijacked via replication abuse into Monero cryptomining, causing performance loss and data-integrity risk.

Researchers at Hunters.io exposed a cryptomining operation that compromised 3,562 distinct Redis servers after scanning 12,966 targets. The attackers used unauthenticated Redis instances and master-replica replication to plant a cron task that downloaded and ran XMRig every five minutes. The miner connects to a mining pool over encrypted port 443 and hides among temporary files. Impact includes high CPU usage, elevated cloud bills, and data-loss risk from altered Redis persistence settings.
