Description

According to news reports, BT Group, the nation's largest telecommunications provider, confirmed an incident with Black Basta ransomware targeting its BT Conferencing unit. According to BT, the impacted servers do not support live conferencing, which remains fully operational. Customer services and other operations of the BT Group were not affected. According to BT, their Conferencing platform had been compromised. As soon as the affected elements were isolated, they were fixed. Despite BT’s description of the incident as an “attempt,” Black Basta has claimed responsibility, alleging they stole 500GB of sensitive data. This includes financial records, user data, NDAs, and confidential documents. The group even shared screenshots and folder listings as proof, threatening to leak the data on their dark web site within a week. BT is actively investigating the breach alongside regulatory and law enforcement agencies. The attack highlights the ongoing threat posed by Black Basta, a Ransomware-as-a-Service (RaaS) operation that emerged in 2022. Known for targeting high-profile organizations worldwide, the group has breached over 500 entities, amassing over $100 million in ransom payments from at least 90 victims by late 2023. Notable victims include Capita, Rheinmetall, Hyundai’s European division, and the Toronto Public Library. This latest attack underscores the need for robust cybersecurity measures as ransomware groups continue to evolve and expand their reach.
