Cybersecurity Alert: Pro-Ukrainian Hacktivist Group Targets Russian Video Conferencing Software
A pro-Ukrainian hacktivist group known as PhantomCore has launched a series of attacks against TrueConf video conferencing servers in Russia since September 2025. Utilizing an exploit chain of three vulnerabilities, the group has been able to gain unauthorized access to various organizations, leading to significant breaches.
The attacks have affected numerous Russian entities, enabling PhantomCore to infiltrate networks, steal data, and deploy malicious tools. The impact has been severe, with compromised systems allowing lateral movement within networks and the installation of remote access tools.
To protect against such threats, organizations are urged to apply security patches released by TrueConf and maintain robust cybersecurity practices, including regular system audits and employee training on phishing threats.
