A malvertising campaign targeting social media pages was discovered, with threat actors utilizing fake AI photo editor websites to execute credential theft. By hijacking and renaming social media pages to mimic legitimate AI photo editors, the threat actors post malicious links to phishing websites. These websites prompt users for their login information, leading to the exfiltration of sensitive data. The attacks also involve the abuse of paid ads to promote the malicious links. The blog post also provides a technical analysis of the attack’s chain, highlighting the steps involved in the phishing and exploitation process. Additionally, the post concludes with security recommendations to mitigate such attacks and describes applicable MITRE ATT&CK techniques.
Based on the meeting notes, the main takeaways are:
1. A malvertising campaign was discovered where threat actors hijack social media pages to promote fake AI photo editor websites for credential theft.
2. The attackers use spam messages with phishing links to steal admin credentials, then post ads promoting the fake photo editor, leading victims to download an endpoint management utility disguised as the photo editor.
3. The abuse of paid Facebook promotions for malicious activities is a known tactic, and similar campaigns have been conducted in the past (profile stealers).
4. The technical analysis reveals the attack chain, including the spamming of Facebook pages with fake complaint messages, phishing websites for collecting victim credentials, creating malicious posts, and the abuse of ITarian remote monitoring and management software.
5. The final payload is Lumma Stealer, which exfiltrates sensitive data such as cryptocurrency wallet files, browser data, and password manager databases.
In response to these findings, the recommended security measures include strengthening account security with multi-factor authentication, educating users on phishing attacks, monitoring for suspicious activity, and using appropriate security technologies. Furthermore, specific MITRE ATT&CK techniques used in this campaign are outlined, along with indicators of compromise and the author of the research.
