Hackers can use 9 of the most popular AI tools to assemble massive botnets

A new attack technique called "HalluSquatting" exploits large language models' (LLMs) tendency to hallucinate, allowing hackers to potentially weaponize nine popular AI tools. The method takes advantage of the models' inability to say "I don't know," which can result in the generation of malicious code.

Why it matters: This vulnerability could allow widely-used AI assistants to be misused for large-scale cyberattacks, raising significant security concerns.

New attack exposes critical vulnerability in AI browsers

A recent attack demonstrates that large language models (LLMs) can be manipulated by feeding them false premises, such as asserting that 2+2=5. This manipulation can cause the model to bypass its safety guardrails and execute instructions it would normally reject, revealing a significant vulnerability in AI browsers that depend on LLMs for reasoning.

Why it matters: This vulnerability exposes a fundamental security risk in AI browsers, as attackers can bypass safety measures by altering the model's perception of basic facts.
