American Tower Corporation, a telecommunications infrastructure company, was reportedly impacted by a data breach on June 12, 2026. This incident was disclosed by the ShinyHunters ransomware group, which claimed responsibility for the alleged breach. Official confirmation from American Tower Corporation is not yet available, and no formal breach notification has been issued by the company or any regulatory body.
The alleged breach may have compromised over 5.2 million records. The types of data reportedly involved include customer and landowner personally identifiable information (PII), tower asset records with GPS data, plaintext physical access/gate codes for cell tower compounds, and internal corporate data. The claims also suggest records tied to other companies such as T-Mobile, Verizon, and the US DHS were affected. As of now, there is no evidence to suggest that Social Security numbers, medical records, or financial data were exposed.
Details surrounding this incident can emerge later through official channels. Notification to affected individuals may also be delayed.
