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

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,

Threat actors with ties to North Korea have been attributed to a sophisticated macOS malvertising campaign that involves redirecting users to fake web pages displaying a full-screen non-existent update sequence to deliver malware as part of a new iteration of the long-running Contagious Interview campaign.

The defining aspect of the attack is that bogus macOS software update screen stealthily

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.

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

The groups move 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.

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

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 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

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
