BT Group

BT Group experienced a ransomware attack from the Black Basta group, leading to the shutdown of some of its servers. This cyberattack put sensitive data at risk, with the group claiming to have stolen 500GB encompassing financial data, organizational records, user and personal documents, NDAs, and confidential information. Although live BT Conferencing services remained operational and other customer services were unaffected, the incident raises concerns about potential data breaches and the overall cybersecurity posture of the company. Screenshots of the compromised data, including passports, were published as proof of the attack.
