Brief summary: while hardening AdGuard’s crypto-jacking protection, we discovered four involved popular websites (mostly streaming) with an aggregated audience of almost a billion people.
We have already told you in our blog (part 1, part 2, part 3) about the problem of stealth mining (the so-called "cryptojacking"), but this story is not going to end. Just two(!) months after its first launch, this technology has been used on thousands of websites with a total estimated traffic of a billion(!) monthly visits. Now, after an additional three weeks have passed, we must regretfully report that cryptomining has soared to even greater heights.
Ad blockers were first to respond to this new menace and implement protection against mining on websites. Thanks to the popularity of ad blockers, a significant portion of Internet users received the necessary protection in a very timely manner. Naturally, "crypto-jackers" are not pleased with this counteraction.
