In this edition of Reporters' Notebook, our journalists discuss the ins and outs of Anthropic's Claude Mythos rollout. How seriously should we take its risks? How big of a deal is it?

A lot of security still comes down to trusting the wrong screen. This week, that screen might be a login page, an install guide, a recruiter call, or a familiar service behaving slightly wrong. Behind it: reused credentials, exposed systems, quiet loaders, abused trust, and exploit paths that should have been harder. Some defenses improved. The loose parts still got found first. Anyway,

A now-patched vulnerability in Azure Cosmos DB could have let an attacker escape the service's Gremlin query sandbox and obtain full read and write access to databases across customer tenants, according to Wiz. Wiz, which codenamed the chain CosmosEscape, said the exploit chain began with a crafted query against a Gremlin database controlled by the attacker. From there, code execution on a

Hidden instructions in a Word document can make Microsoft 365 Copilot rewrite figures in a report, then copy the same instructions into the finished file. Håkon Måløy disclosed the technique on July 28, 144 days after reporting it to Microsoft. In his proof of concept, the internally generated file triggered the same behavior when it was used in a second Copilot drafting session. Måløy's

Network firewalls are the workhorses of modern cybersecurity. They are trusted to protect the network, blocking malicious traffic and preventing intrusions and breaches. And for decades, network security teams have built controls around a relatively stable model: users connect to applications, applications exchange data, and security tools inspect packets, protocols, and destinations. Firewalls

South Korean authorities and four security firms have disclosed a state-sponsored campaign that compromised trusted domestic websites. The attackers used those sites to exploit locally installed financial-security software and infect targeted visitors with SIGNBT or COPPERHEDGE backdoors. A compromised page could infect a system running a vulnerable AnySign4PC version without a prompt or

The Chinese cybercrime group known as Silver Fox has been observed using new drivers as part of bring your own vulnerable driver (BYOVD) attacks targeting a Japanese organization in the industrial manufacturing sector to ultimately deliver ValleyRAT (aka Winos 4.0) for persistent remote access. "In this campaign, the group combines new vulnerable-driver abuse, newly observed abuse of legitimate

The Russian threat actors recently linked to the exploitation of a now-patched vulnerability in Zimbra have been observed exploiting another vulnerability, this time in Microsoft Outlook Web Access (OWA), to target U.S. and European government entities, as well as the telecommunications, financial, hospitality, and aerospace sectors. The activity, which began on July 22, 2026, involves the

The Federal Communications Commission (FCC) added foreign-produced mobile robots and networked power inverters to its Covered List on July 28. The move generally prevents new models from receiving the equipment authorization required for import, marketing, or sale in the US. Previously authorized models can still be sold, and devices people already own are unaffected. Federal purchases and use

Amazon has tied the September 2025 hijack of the npm packages debug and chalk to North Korea. For ten months, the incident sat in the public record as crypto theft: a maintainer phished through a lookalike npm domain and a wallet-draining script pushed into at least 18 packages carrying more than 2 billion weekly downloads between them. The original Aikido and Wiz reports did not attribute the

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a newly disclosed security flaw impacting Cisco Secure Firewall Management Center (FMC) Software to its Known Exploited Vulnerabilities (KEV) catalog, following reports of zero-day exploitation. The vulnerability, assigned CVE-2026-20316 (CVSS score: 5.3), could permit an unauthenticated, remote attacker to log

The organized crime groups have moved from goods to services and continue to traffic people from at least 80 countries, costing nations in the region at least $88 billion in 2025 alone.

A premium-grade malware-as-a-service offering takes flight with multiple threat groups, building infostealers that drain victims' bank accounts.
