Massive YouTube Campaign Targeting Over 100 Applications to Deliver Info Stealer

Threat Actors Create Phishing Websites for Mass Infection

Cyble Research & Intelligence Labs (CRIL) identified massive phishing campaigns running on YouTube as tutorials for downloading and installing cracked software, Games for free.

The video tutorial tricks the users into installing Information stealer from the link given in the video description and lures them into believing it is a crack for their desired software.

We have seen many similar campaigns in the past, downloading Pennywise and Redline stealer. In these types of campaigns, the Threat Actor (TA) usually hosts the malicious file in the free file hosting platform.

Still, in this case, the TA has created phishing pages mimicking legitimate websites that provide service to users for downloading various software, games, and other tools.

Going through the different campaigns, we identified several phishing websites mentioned in the video description. The TA has created phishing pages to increase the chances of successful infection. Also, the impact of this campaign can be calculated based on the number of views on each video posted. The maximum number of views we observed on a single video is 18k, indicating the campaign is widespread.

The below image depicts the comments in the YouTube videos. Similar comments from different YouTube videos conclude that the TA adds these to convince users to think this software is legitimate.

YouTube Campaigns Analysis:

During our research, we observed that the TA responsible for running these campaigns primarily targets people looking to get paid software for free such as games, programs, etc. To get this software for free, people usually search keywords like “software cracks,” “keygens,” etc. The search result of these keywords redirects users to these YouTube videos, guiding them to install malicious executables pretending to be the software they wanted to install.

Most of the binaries hosted on these phishing sites act as either downloaders or droppers for the stealer payload. The malware infection happens in multiple stages and at the end, executes the stealer payload. These stealers mainly exfiltrate sensitive user data such as cookies, system information, login credentials, etc. to their Command and Control (C&C) server.

This exfiltrated data is referred to as Stealer Logs , which are usually sold on cybercrime marketplaces and can be leveraged by other TAs to target individuals or get into corporate networks. The phishing campaign discussed in this blog was mainly distributing Vidar and RecordBreaker stealer.

Vidar Stealer

Vidar InfoStealer is based on C/C++ programming language. The Vidar malware family, which was first identified in 2018, can steal sensitive data from the victim’s PC. This includes banking information, saved passwords, IP addresses, browser history, login credentials, and crypto wallets, which can then be transferred to the TAs Command and C&C. We witnessed in past also where TAs used delivery mechanisms such as spam mail, cracked software, keygens, etc. to distribute this malware.

RecordBreaker Stealer

RecordBreaker stealer is suspected to be a recent version of the Raccoon stealer, which was spotted in the wild in 2022. While executing, this stealer performs several GET\POST requests with Command and Control (C&C) Server. Initially, it fetches the configuration and DLLs and then exfiltrates the victim’s data to C&C using a POST request. The stealer can also deliver other malware payloads based on the configuration’s settings. The figure below shows the stealer receiving configuration file.

Conclusion

Threat Actors are constantly enhancing their techniques to deliver malicious programs. In this particular case, the TA uses YouTube channels to spread malicious payloads hosted on phishing websites. This campaign primarily leverages YouTube videos (with step-by-step tutorials) to trick users into installing malicious programs on their systems. CRIL has been observing increasing trends in social media scams of late.  

Cyble Research and Intelligence Labs’ mission is to continuously monitor and alert our audience to high-tech cyber scams and protect our clients in cyberspace by supporting them in achieving their goals.
