The U.S. Environmental Protection Agency (EPA) is facing a data leak, carried out by a hacker operating under the alias USDoD. This data leak has exposed personal and sensitive information belonging to more than 8.5 million users, including customers and contractors.

Regarding the data leak, the hacker told Hackread.com that the leak contains the entire contact database of the agency. Analysis conducted by Hackread.com indicates that the data provided by USDoD appears to be legitimate; however, conclusive verification can only be provided by the U.S. Environmental Protection Agency.

Hackread.com has notified the U.S. Environmental Protection Agency (EPA) and CISA regarding the data breach. Any response from either agency will lead to an update to this article.


UPDATE: 22:02 Monday, 8 April 2024 (GMT) – CISA has responded to Hackread.com confirming that the incident has been investigated by the FBI and the leaked data is already publicly available.

“FBI engaged EPA on Friday 4/5 where EPA determined the data reportedly taken as publicly available and the reported compromise to be a non-issue, per their internal hunting elements.”


USDoD’s Response

During a conversation with Hackread.com, the hacker stated that they never breached the EPA and that the data was indeed publicly available. They claimed to have extracted it from a Philadelphia-based third-party platform called DataRefuge.

The hacker also admitted that their post on Breach Forums should have clarified that there was no data breach of the EPA involved in the incident. However, they emphasized that the data is 100% authentic and of high importance, comparable to if an agency had been breached.

The Good and Bad news

The good news amidst this breach is the absence of passwords. However, the seriousness of the situation can be understood by the fact that the leaked data is now circulating within Russian hacker and cybercrime forums.

Devastating First Quarter of 2024 for US So Far

The first quarter of 2024 has proven to be quite challenging for the United States, a nation that holds influential global power and consequently becomes an attractive target for cybercriminals. Despite ongoing efforts to strengthen its critical infrastructure, the country has faced a surge in successful cyber attacks, resulting in widespread disruption and compromise.

In January, EquiLend, a prominent financial technology firm, fell victim to a large-scale ransomware attack. As a result, it was confirmed that the incident also led to a data breach, exposing sensitive employee information.

March witnessed the cyber attack from IntelBroker hacker against Acuity Inc., a federal contractor, resulting in the exposure of critical records belonging to U.S. Citizenship and Immigration Services (USCIS) and U.S. Immigration and Customs Enforcement (ICE). Although initially denied, Acuity Inc. eventually acknowledged the hack.

In February, the same hacker targeted the security of Los Angeles International Airport, compromising the personal data of 2.5 million private plane owners. Shortly thereafter, in March, American Express disclosed a significant data breach involving third-party contractors, impacting its cardholders.

The latest alleged data breach occurred on April 4, 2024, when the IntelBroker hacker leaked personal data belonging to over 22,000 Home Depot employees on BreachForums.
