1514865 - Blocklist malicious add-ons injecting ads

Status: RESOLVED FIXED

(Toolkit :: Blocklist Policy Requests, enhancement)

Description

[rctgamer3]

These add-ons are installed from hard-to-escape .cool TLD domains. These add-ons have remote script injection. Functions include ad injection from different networks and more.

Probably similar ones floating around.

I found a bunch of other add-ons using .cool domains that have potential for being similar. I'm running a query for more of them which should be through tomorrow morning.

The ones you posted are definitely affected, they inject remote scripts and mask as other add-ons. Inspecting the remote scripts, they seem to inject content scripts into all urls that exfiltrate data.

Most interesting piece of code I found while looking at these: ﾟωﾟﾉ= /｀ｍ´）ﾉ ~┻━┻  . I learned about two new obfuscators in the process.

The add-ons all have a remote script injection and exfiltrate data, some are obfuscated in different ways.
I found a total of 241 add-ons, many of which are already blocked. Here is the remaining list:
