Cellcom Cyberattack Causes Outage; Kettering Health Cancels Procedures; Abilene Hit by Qilin Ransomware Stealing 477 GB

Cellcom, a mobile carrier, has confirmed that a cyberattack caused an extended service outage, initially blamed on a technical issue. Texting services have been restored, but calling remains limited to communication between Cellcom customers only. The company stated there is no evidence that customers' personal information, including names, addresses, or financial data, was compromised. The outage was officially attributed to a "cyber incident." Meanwhile, Kettering Health is experiencing a system-wide technology outage due to a ransomware attack, leading to the cancellation of elective procedures and reports of patients receiving scam calls. Cybersecurity experts have identified the attack as ransomware. In Abilene, Texas, the City has confirmed a ransomware attack by the Russian-based group Qilin, which claims to have stolen 477 GB of data and set a ransom deadline for May 27, 2025. The city has refused to pay the ransom but assured residents that essential services continue as efforts to resolve network outages are underway. Other notable recent ransomware incidents include breaches at France's INDIGO Group, Italy's STIGA, Spain's Valentin Hotels & Resorts, and the UK's West Lothian Council, with data thefts ranging from hundreds of gigabytes to multiple terabytes.
