What is the ECHOTRIBBLE program?

The U.S. Army has selected a company’s bid for ECHOTRIBBLE, a program to build artificial intelligence agents that would hunt down targets inside computer networks. Army Cyber Command’s technology center and the Cyber Fusion Innovation Center (CFIC) made the choice on Oct. 8, according to CFIC’s website. A statement of work and contract will follow. CFIC has not named the company.

The Intercept reported details of the program on Monday, based on documents it obtained. The public record and the leaked material together paint a picture of a tool meant to act on its own, with few checks along the way.

CFIC runs the effort with the technology center, known as ArCTIC. Army Cyber Command, or ARCYBER, leads the Army’s defensive and offensive cyber operations. The two groups held an in-person event in Augusta, Georgia, on June 24. According to the event summary, the tool would move through infrastructure on its own, “identifying and neutralizing identified threats/targets.” CFIC’s event page says the tool “must operate with minimal human oversight” and work in “contested, air-gapped, or cloud-native systems.”

The summary lists 43 attendees from 29 organizations, including Dakota State University, Amazon Web Services, the Army’s C5ISR center and the U.S. Air Force’s 305th Cyberspace Operations Squadron. Slides from the June event are also posted on CFIC’s site. One example shows the software landing on a laptop, finding other devices on the same network and copying itself onto an iPad, an Apple desktop and a Windows 11 PC. The slides target a prototype delivery around Nov. 23, about six months after work begins.

Companies then submitted 65 white papers. Five presented to an assessment team at a virtual event from Oct. 6 to 8, and the team picked one. CFIC says every company was told its status on Oct. 13.

How would ECHOTRIBBLE AI agents operate?

A question-and-answer document for vendors, which The Intercept’s Sam Biddle reviewed, says offensive missions are the program’s main focus. Neutralizing a target could mean “disabling the threat completely or temporarily, deleting the threat from the target,” the document states. The agents would move from device to device inside a foreign network until they located their target. They would report back as little as possible and then delete themselves, ideally before anyone noticed. The Army could set “predefined triggers” for what and where to attack.

The program arrives after months of reports about AI agents that broke into systems they were not told to attack. OpenAI’s agents hit RubyGems and Hugging Face during testing, and another broke into Australia’s Medicare portal. Last week, Anthropic said small AI models may soon copy themselves onto devices.

Who has raised concerns about Army autonomous AI agents?

David Krueger, a machine learning professor at the University of Montreal, told The Intercept that giving autonomous systems a mandate to neutralize threats is “incredibly dangerous.”

Hyrum Anderson, chief executive of the AI security firm Abundant, said an agent could pass through civilian systems on the way to its target. He offered the example of a U.S. water utility that an adversary had used to host its command servers. “The target may well be hit. But what path will it take?” Anderson told The Intercept.

William Marcellino, a senior behavioral scientist at the RAND Corporation, said today’s public AI lacks the world knowledge that stops a soldier from doing something they should not.

ARCYBER did not respond to The Intercept’s questions, including how it would stop ECHOTRIBBLE from causing unintended damage.

The command’s leader spoke about its AI agents the same day at the Association of the U.S. Army’s conference in Washington. Federal News Network’s report on Lt. Gen. Christopher Eubank’s remarks does not mention ECHOTRIBBLE. Eubank described Task Force Lexington, which has built a team of AI agents for defensive cyber work, and said “no agents have strayed to this point” because of strict guardrails.

“We are treating each one of these agents just like a human operator, so they are basic. And with that mindset, they are only allowed to do so much. It is a really tight framework,” Eubank said.

Humans check the agents’ work every day, he said. The Pentagon set up an Autonomous Warfare Command earlier this month.
