A large-scale scam campaign targeting Facebook Messenger users all over the world has been detected by Group-IB. Scammers used shortened links created with the help of such services as linktr.ee, bit.ly, cutt.ly and rb.gy. Users who fell victim to this scheme risk leaking their personal data and have their account hijacked. The scam first came into the spotlight in the summer of 2020, with analysts based in Asia and Europe having detected traces of the same fraudulent campaign.
