Github Page Redirect

The links in the posts lead to a static Github page with a Facebook login panel. After the victim entered the Facebook information on the static phishing page, the information was transmitted to 2 different places. First to the Firestore database, then to a domain owned by the attackers.

In order to prevent the spread of such phishing pages, Facebook blocks pages containing malicious links from advertising. However, the attackers initially used Bitly (link shortening) links to point to a harmless page. After the approval of the post’s suitability for advertising, it was determined that they changed the post link to point to the phishing page.

About 500 GitHub repositories containing phishing pages have been discovered as part of the same campaign. It seemed that the pages were created on GitHub 5 months ago. It was determined that the domain name used in the campaign was first created on April 3, 2020, behind CloudFlare and was registered with GoDaddy. Four more domains suspected of belonging to the same group have been identified.
