shinyhuntersThis record tracks a ransomware attack claimed by the shinyhunters group against American Tower Corporation. It collects the publicly disclosed attack details — sector, location and timeline — as published on the operator's leak site and indexed by Breach House.
Window Zero
EXPOSURE GAPWindow Zero is the time the breach stayed in the open before anyone said so — the gap between when the attack was first discovered on the operator's leak site (t1) and when it was publicly disclosed (t2). The wider this window, the longer victims, staff and customers were exposed with no warning.
Attack Summary
Over 5.2 million records consiting of a significant amount of customer and landowner PII, other records tied to other companies such as T-Mobile, Verizon, and the US DHS, several tower asset records containing GPS data and plaintext physical access/gate codes for cell tower compunds across the United States, thousands of internal corporate data, and a lot more were compromised. We urge you to reach out. This is a final warning to reach out by 15 June 2026 before we leak along with several annoying (digital) problems that'll come your way. Make the right decision, don't be the next headline. | Updated: 12 June 2026 | Warning: FINAL WARNING PAY OR LEAK
