Cybersecurity in the age of instant software

AI is rapidly changing how software is written, deployed, and used. Trends point to a future where AIs can write custom software quickly and easily: “instant software.” Taken to an extreme, it might become easier for a user to have an AI write an application on demand — a spreadsheet, for example — and delete…

A nearly undetectable LLM attack needs only a handful of poisoned samples

Prompt engineering has become a standard part of how large language models are deployed in production, and it introduces an attack surface most organizations have not yet addressed. Researchers have developed and tested a prompt-based backdoor attack method, called ProAttack, that achieves attack success rates approaching 100% on multiple text classification benchmarks without altering sample…

Chained vulnerabilities in Cisco Catalyst switches could induce denial-of-service

Cisco’s widely deployed Catalyst 9300 Series enterprise switches have four security vulnerabilities, two of which could be chained to cause a denial-of-service outage, infrastructure security company Opswat has revealed. The two most operationally significant are CVE-2026-20114 and CVE-2026-20110, which the researchers found could be chained to make possible a dangerous privilege escalation. Opswat’s Unit 515…
