FDA’s Elsa Tool Faces Criticism For Hallucinating Scientific Data

The FDA’s new AI tool Elsa promises faster drug approvals, but medical experts warn this tool generates fabricated research, which produces additional safety risks.

In a rush? Here are the quick facts:

  • The FDA launched an AI tool named Elsa to aid drug approvals.
  • Elsa sometimes invents studies or misstates existing research.
  • Staff say Elsa wastes time due to fact-checking and hallucinations.

In June, the FDA launched Elsa as their new artificial intelligence tool to accelerate drug approval procedures. FDA Commissioner Dr. Marty Makary declared the system would be completed before schedule while remaining under budget.

However, the FDA staff members recently told CNN that Elsa requires further development before it can be used in practical applications.

Elsa is supposed to help FDA scientists by data summary work and review process optimization. However, CNN notes that current and former FDA employees report that Elsa hallucinates and generates false information. Indeed, the tool seems to fabricate new studies or distort existing ones, which makes it risky to use in serious scientific work.

“Anything that you don’t have time to double-check is unreliable. It hallucinates confidently,” said one FDA employee to CNN. Another added, “AI is supposed to save our time, but I guarantee you that I waste a lot of extra time just due to the heightened vigilance that I have to have.”

CNN notes that currently, Elsa isn’t used for drug or device reviews because it can’t access important documents like company submissions. The FDA’s head of AI, Jeremy Walsh, acknowledged the issue: “Elsa is no different from lots of [large language models] and generative AI […] They could potentially hallucinate,” as reported by CNN

FDA officials say Elsa is mostly being used for organizing tasks, like summarizing meeting notes. It has a simple interface that invites users to “Ask Elsa anything.”

Staff are not required to use the tool. “They don’t have to use Elsa if they don’t find it to have value,” said Makary to CNN.

Still, with no federal regulations in place for AI in medicine, experts warn it’s a risky path. “It’s really kind of the Wild West right now,” said Dr. Jonathan Chen of Stanford University, to CNN.

As adoption of AI in science is growing rapidly, with over half of researchers saying AI already outperforms humans in tasks like summarizing and plagiarism checks.

However, significant challenges remain. A survey of 5,000 researchers found 81% worry about AI’s accuracy, bias, and privacy risks. Many see the lack of guidance and training as a major barrier to safe AI use.

Experts emphasize the urgent need for clearer AI ethics and education to avoid misuse. While AI shows promise, researchers agree that human oversight is still crucial to maintain scientific integrity.

Official Gaming Mouse Software Hosted Malware For Weeks

The official software of Endgame Gear hosted XRed malware for two weeks, which endangered user security, until the clean file was reuploaded.

In a rush? Here are the quick facts:

  • Endgame Gear mouse software hosted malware for at least two weeks.
  • The infected file came from Endgame Gear’s official content delivery network.
  • Antivirus tools caught malware, protecting many users during the infection window.

The Endgame Gear OP1w 4K V2 gaming mouse software download from the official manufacturer site contained malware for at least two weeks, as first reported by PCGamer . The dangerous XRed remote access trojan (RAT) malware enabled attackers to gain control of compromised computers.

Reports first surfaced on the MouseReview subreddit, where users noticed the configuration tool contained malicious code. According to Redditor Admirable-Raccoon597 , the infected version was available for download from at least July 2 until July 17, 2025.

The infected file came directly from Endgame Gear’s official content delivery network (CDN), not a third-party source, as noted by PCGamer.

The official Endgame Gear representative validated the problem through Discord before uploading a clean version of the file. PCGamer notes that the company has not released any official announcement about the incident to the public.

Broadcom , a cybersecurity firm, explained the XRed backdoor has “sophisticated capabilities as it collects system data information that it transmits the data using SMTP to email addresses.” The malware also hides itself using hidden directories and registry keys, and can spread via USB drives like a worm, as noted by PCGamer.

Fortunately, many users were likely protected, as antivirus tools like Windows Defender and Google Chrome flagged the malware.

The incident demonstrates that official software downloads can create security threats, which underlines the need for antivirus protection and careful monitoring among gamers.
