“SubdoMailing” — Thousands of Hijacked Major-Brand Subdomains Found Bombarding Users With Millions of Malicious Emails

Guardio Labs uncovers a sprawling campaign of subdomain hijacking, compromising already over 8,000 domains from esteemed brands and institutions, including MSN, VMware, McAfee, The Economist, Cornell University, CBS, Marvel, eBay and others.

In our detailed analysis, we disclose how we detected this extensive subdomain hijacking effort, its mechanisms, its unprecedented scale and the main threat actor behind it. Furthermore, we developedthe “SubdoMailing” checker — a website designed to empower domain owners to reclaim control over their compromised assets and shield themselves against such pervasive threats. This report not only sheds light on the magnitude of the issue but also serves as a call to action for enhancing domain security against future exploits.
