Rewterz Threat Alert – Raccoon Infostealer – Active IOCs

Severity

Medium

Analysis Summary

Also known as “Racealer,” Racoon is used to steal sensitive and confidential information including login credentials, credit card information, cryptocurrency wallets and browser information (cookies, history, autofill) from almost 60 applications. Raccoon stealer is written in C++ and it has a wide range of methods and features for stealing data from popular browsers, email clients and cryptocurrency wallets. The malware is delivered via exploit kits that use browser-based vulnerabilities to redirect victims to landing pages injected with exploit codes. It’s also spread via phishing campaigns convincing targets to execute the malicious payload or macros. The malware gathers information about the machine like the OS arch and version, system language, hardware information and installed applications. In addition, it can take screenshots from the user’s machine if that was enabled by the attacker’s configuration. After fulfilling all its stealing capabilities, Raccoon gathers all the files that it wrote to the temp folder into one zip file named Log.zip. Now all it has to do is send the zip file back to the C&C server and delete all traces of itself.
