Roblox En La Nube Chrome Extensions Steal Roblox Currency, Uses Discord
We recently discussed how cyber criminals are using the popular voice/chat client Discord to steal cookies from the running Roblox process on a Windows PC. Since then, we’ve noticed another attack going after the same information, only this time it is via Chrome extensions (CRX files).
While it currently only targets Roblox users, the same technique can be used to steal cookies from any website. The stolen information is sent via Discord, but this could also be configured to use other chat platforms. We learned this particular Chrome extension was, in fact, for sale on the Dream Market underground marketplace for only 99 cents:

We obtained samples of this bot using the following file names: ROBLOX BOT.zip, Crm5extension.crx, Roblox Enhancer.crx, and DankTrades.zip. The first .ZIP file contains a file named bgWork.js.

Searching for the terms CRM5 or bgWork.js lead right back to the forum v3rmillion.net. This underground marketplace forum is a hotspot for Roblox hacks, where users even trade ROBUX (the in-game currency of Roblox) for other work or products.
