Anthropic’s Opus 5 Is Better at Resisting Prompt Injection

The chart is interesting. On the IPI benchmark, Opus 5 improved over Opus 4.8, reducing the probability of an attacker succeeding within 15 attempts from 5.5% to 2.0%, and from 0.5% to 0.2% on 1 attempt. It also improved on Sonnet 5 (5.9% at k=15) and Mythos 5 (2.6%), making it the most robust model evaluated. Opus 5 also outperformed all non-Claude models on this benchmark. The most robust non-Claude model was Muse Spark at 16.5% within 15 attempts—more than eight times Opus 5’s rate. The most capable GPT 5.6 variant, Sol, was comparable to its predecessor GPT 5.5 (20.0% versus 20.8% within 15 attempts), and was 10 times as likely to be successfully attacked as Claude Opus 5 at 2.0%. The other GPT 5.6 variants are less robust, at 30.4% (Terra) and 43.9% (Luna). A single attempt against GPT 5.6 Sol succeeded 3.1% of the time, higher than the 2.0% an attacker achieved against Opus 5 after fifteen attempts…

HollowFrame Loader Deploys Matryoshka Backdoor in Spear-Phishing Attack on Law Firm

Cybersecurity researchers have shed light on a previously undocumented Go-based loader framework called HollowFrame and a Rust-based malware family tracked as Matryoshka. According to Blackpoint Cyber, the intrusion sequence begins with a spear-phishing message containing a link to an encrypted archive, which holds a Windows Shortcut (LNK). Executing the file triggers a multi-stage chain that

Cybercrime goes subscription: AI, malware and infrastructure on demand

Cybercrime has become a commercialized ecosystem where criminals can buy or rent nearly every capability needed to launch sophisticated attacks. These services provide anonymity, plausible deniability, and access to short-lived infrastructure that is difficult to detect, attribute, and disrupt, enabling low-skilled actors to operate at scale, according to the Infoblox 2026 Threat Landscape Report. “Cybercrime is becoming more efficient, automated, and harder to stop. Driven by economics and fueled in part by frontier AI, it … More → The post Cybercrime goes subscription: AI, malware and infrastructure on demand appeared first on Help Net Security.
