In response to the discovery of a new attack that compromises victims’ VPN (Virtual Private Network) accounts to compromise messaging app, Telegram, the Nigerian Communications Commission’s Computer Security Incident Response Team (NCC-CSIRT) has advised users to adopt two-factor authentication to protect their Telegram accounts and to not download unknown Advanced IP Scanner Software.Ukrainian cyber experts discovered the attack, which uses Vidar Malware (Vidar Stealer) to steal Telegram session data, which in the absence of configured two-factor authentication and a passcode, allows unauthorized access to the victim’s telegram account and corporate account or network.The malware, which exploits unauthorized access to users’ Telegram accounts and corporate accounts to steal data, targets platforms across iOS, Android, Linux, Mac and Windows Operating Systems. “The Ukrainian CERT alleged that a Somnia Ransomware was created to be used on Telegram that tricks users to download an installer that mimics ‘Advanced IP Scanner’ software, which contains Vidar Malware. The installer infects the system with the Vidar stealer, which steals the victim’s Telegram session data to take control of their account. “The threat actors abuse the victim’s Telegram account in some unspecified manner to steal VPN connection data (authentication and certificates). If the VPN account is not protected by two-factor authentication passcode, the hackers use it to gain unauthorized access to the victim’s employer’s corporate network”, the alert and advisory states.
