AECOM Data Breach? Lawyers Investigate Hackers' Claims

Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of reports of a possible AECOM data breach.

As part of their investigation, they need to hear from individuals who believe their information may have been put at risk , including current and former AECOM employees and clients.

Reports Emerge of Possible AECOM Security Breach

AECOM, a multibillion-dollar infrastructure consulting company based in Texas, may have suffered a data breach.

According to a September 17, 2026 post on dark web monitoring site Ransomware.live , hacker group Metaencryptor claimed to be responsible for an attack on AECOM that allegedly affected 1.22 terabytes of data. The suspected attack was estimated to have occurred the same day the post was made.

HookPhish , another cybersecurity blog, similarly stated that Metaencryptor was behind a suspected attack on the engineering firm.

At the time this post was made, no additional information was available the scope or nature of the unconfirmed AECOM data breach.

If you're affiliated with AECOM and suspect your information could have been put at risk, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, lost time, out-of-pocket costs, and more.

A successful case could also force AECOM to ensure they take proper steps to protect the information they were entrusted with.

If you're concerned your information may have been exposed in the alleged AECOM data breach, fill out the form on this page to get in touch with us.

An attorney or legal representative may then reach out to you to explain more this investigation and ask you a few questions.

Remember, there is no cost to get in touch, and you are under no obligation to take action after speaking to someone.
