Edelson Lechtzin LLP has launched an investigation into potential class action claims following a reported data breach at AECOM, a major infrastructure and engineering firm. The breach allegedly involved the theft of over 1 terabyte of data, raising concerns about the personal information of employees and clients.

The cyberattack reportedly occurred on or around September 17, 2026, with the hacker group Metaencryptor claiming responsibility. They asserted that approximately 1.22 terabytes of data were compromised. Additionally, another group, BrainCipher, is linked to a separate data leak involving around 670 gigabytes associated with AECOM.

Individuals who have received a data breach notification from AECOM or suspect their personal information may have been exposed can seek a free and confidential case evaluation from Edelson Lechtzin LLP. The firm aims to assist those affected in understanding their rights and potential claims.

While the exact scope of the breach has not been confirmed, Breachsense, a dark web monitoring service, reported that numerous AECOM-related credentials are circulating online, including thousands associated with @aecom.com accounts. This situation intensifies the risk of identity theft and fraud for those whose data may have been compromised.

Current and former employees, clients, and anyone else whose information AECOM may have held could be impacted. Edelson Lechtzin LLP’s investigation reflects the growing concern over data privacy and the legal avenues available to individuals whose sensitive information is at risk.

As the situation develops, experts recommend that affected individuals regularly review their account statements and credit reports for any suspicious activity. They should also consider placing fraud alerts and enrolling in credit monitoring services.

This announcement follows a troubling trend of data breaches affecting large corporations, underscoring the need for solid cybersecurity measures. The investigation by Edelson Lechtzin LLP signifies a critical step for those potentially impacted by the AECOM breach to pursue justice and compensation.
