A misconfigured open directory on IP address 86.53.111[.]212:8080 exposed critical details of an active cybercrime operation, including Moobot botnet source code, denial of service tools with attack records, and a fraudulent Chinese identity verification service. The exposed directory also contained StresD Pro+, a multi-user DDoS panel with 16 registered accounts and 32 recorded attacks on the collection date. The recovered Moobot source code revealed a previously unknown dormant download-and-execute functionality that represents the most plausible mechanism behind APT28's repurposing of Moobot for deploying malware to compromised devices. Despite a 2024 court-authorized disruption by the U.S. Department of Justice, Moobot remains active as of August 2026, with one active C2 server observed conducting over 500 short-duration attacks throughout the month, consistent with DDoS-as-a-service operations.

A Chinese-speaking cybercrime group, REF4033, has orchestrated a massive SEO poisoning campaign, compromising over 1,800 Windows web servers worldwide using the BADIIS malware. The campaign operates in two phases: serving keyword-stuffed HTML to search engine crawlers and redirecting victims to illicit websites. The group deploys BADIIS, a malicious IIS module, to hijack legitimate servers for manipulating search engine rankings and facilitating financial fraud. The campaign primarily targets the APAC region, with China and Vietnam accounting for 82% of compromised servers. Victims span various sectors, including government agencies, educational institutions, and financial services. The attackers use sophisticated techniques for stealth and anti-tampering, employing Chinese encryption standards and commercial obfuscation tools.
