Here is a link from an SMS I received abev1o.yzv.jp.

This link redirects to a somewhat random website (twitter, youtube, CNN, and others).

I downloaded the page using curl:


It looks like the code is using window.location. The websites the script redirects to seem to be legit. What is the purpose of this?

    The script sets cookies and sends people off somewhere else... As for why? Maybe it's an altruistic AI sent from 800 years in the future to subtly influence humanity to bring about a true post-scarcity society. (We don't know why, and any conjecture on our point is just conjecture.)

  • you are asking "why" for some lines in the code, or purpose of such program (you can modify "random" direct to "specific" direct of course)? now it seems not a security-related question?

  • Decoding random code on random sites is not really what we do here. We would be flooded with randomness. I'm not sure what any answer would tell you, either. The code you posted does not show any redirect code. So there's a lot missing, too.

  • To know the purpose, you need to know everything it is doing. To do that, you need to analyse the behaviours and the code. There are many online tools that analyse behaviours.

  • I ran the link through Cuckoo sandbox, and it is a malware/ransomware dropper: cuckoo.ee/analysis/1464559/summary
