From Baidu to Google’s Open Redirects
Last week, we described how an ongoing massive malware campaign began using Baidu search result links to redirect people to various ad and scam pages.
It didn’t last long. Soon after the publication of that article, the bad actors changed the links to use compromised third-party sites and a couple of day later they began using Google’s goo.gl URL shortening service.
This is a snippet from their decoded script:
The Redirect Chain
If you check Google’s own information about that shortened URL, it shows that the URL redirects to another Google owned URL maps.app.goo.gl which looks quite benign.
