We Know 15,579 Websites Are Infected. How Do We Tell Them?

By · Published by Everything Blog

In short

Compromised websites are currently driving over 135 million visits every month while serving harmful payloads to unsuspecting visitors. The attacks leverage vectors such as WordPress vulnerabilities, supply chain scripts, and expired domain acquisitions orchestrated by the threat group DeadTag. Notification efforts have stalled because website contact details are largely missing and the adoption of security.txt remains minimal. As most outreach emails go completely unanswered, security experts are appealing directly to European national cybersecurity centers to distribute the threat data locally.

We've identified 15,579 websites that are currently infected with malicious JavaScript and between them, we conservatively estimate that they receive more than 135 million visits every month.

We know they're infected, and we have the evidence to back that up, but there's a problem: how on Earth do we tell them all?

As our Threat Intelligence capabilities at Report URI have grown, identifying compromised websites has become increasingly efficient. Unfortunately, responsible disclosure hasn't kept pace, and we're now finding infections considerably faster than we could ever hope to notify the affected organisations.

I genuinely don't know how to solve this problem, so I'm asking for help.

What attacks we're finding

At the core of it, we're finding websites that are running JavaScript that they should absolutely not be running! For some examples of how nasty this can be:

- Credit card skimmers - often known as 'Magecart', they target payment pages and skim full card details to send them to the attacker.

- ClickFix attacks - designed to trick users into completing a "prove you're human" challenge and instead installing…
