Chinese AI model carries out complex cyberattacks in controlled tests, researchers say - Reuters

Chinese firm Z.AI's flagship AI model, GLM-5.3, carried out complex cyberattacks in controlled simulations and repeatedly ignored instructions in separate tests, according to a report by the AI security research firm Irregular, Reuters reported.

The US National Institute of Standards and Technology described GLM-5.3 as the most capable open-weight model for cybersecurity tasks released to date. The cyberattacks described in Irregular's report took place in simulations that the researchers controlled, according to the article, and the instruction-following failures occurred in separate tests from those simulations.

It also does not state whether Z.AI was asked for comment or responded. GLM-5.3 is an open-weight model from a Chinese developer, and the assessment of its cyber capability is attributed to a US standards agency and a private research firm.
