ThreatsDay: AI-Powered Hacking, 370 Chrome Flaws, SonicWall Attacks, DNS Hijacking + 22 More Stories

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, here's the mess. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Azure Cosmos DB Flaw Exposed Platform-Wide Key That Could Access Any Database

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 multi-tenant gateway exposed a platform-wide signing secret and a regional account directory, allowing the researchers to locate a target and retrieve its primary account key. Microsoft blocked the vulnerable Gremlin entry point within 48 hours of the November 2025 report. Wiz said Microsoft completed the longer-term fix across all regions in July 2026 and eliminated the platform-wide key. "We appreciate Wiz's work in identifying and reporting this issue through coordinated vulnerability disclosure," a Microsoft spokesperson told The Hacker News. "We have fully addres...

Microsoft Copilot for Word Can Copy Hidden Prompts Into New Documents

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 timeline says Microsoft confirmed the reported behavior on March 31 and deployed two mitigations. The first blocked the original prompt wording; the second upgraded the underlying model to GPT-5.5. He said the full chain worked with modified instructions on GPT-5.6 the next day, and the attack class still reproduced on July 28. "The vulnerability class therefore remains exploitable at the time of publication," Måløy said. The attack is not zero-click and does not execute conventional malware. It requires a Copilot drafting or editing operation, and the malicious document must en...

The Network Has Become the Control Plane for AI Security

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 became exceptionally good at understanding where traffic was going and whether it should be allowed. But just as AI is reshaping every aspect of the business world, it's also had a monumental impact on how security teams view network traffic and the firewall. AI is driving new network dynamics that traditional security policies were never designed to govern. Employees, applications, and agents send prompts, call models, connect to services, and trigger actions across the environment, all activity most firewalls can't see, let alone understand. AI agents interact with external servic...

Hackers Exploit AnySign4PC via Hacked Korean Sites to Install Backdoors Without Prompts

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 user-initiated download. The Korea Internet & Security Agency (KISA) says AnySign4PC versions 1.1.4.4 through 1.1.4.6 are affected and lists version 1.1.5.0 as the fixed release. It recommends deleting vulnerable installations. AhnLab refers to two exploited products only as financial-security software A and I. Its report does not disclose their identities, affected or fixed versions, or vulnerability identifiers. AhnLab said it identified evidence of related attacks at 72 organizations in 2026. The company also found 15 legitimate websites used as watering holes. Its investigation also foun...

SilverFox Targets Japanese Manufacturer with 3-Driver BYOVD Chain and ValleyRAT

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 applications for DLL sideloading, defense evasion, and layered recovery mechanisms to keep ValleyRAT running," Cato Networks researchers Shani Kurtzberg, Tomer Pugach, Dr. Guy Waizel, Zohar Buber, Idan Tarab, and Shani Kurtzberg said in an analysis. The attack chain begins with an invoice-themed phishing lure that uses attacker-controlled content hosted on legitimate QQ and Tencent Cloud services to trigger a DLL side-loading chain via a ZIP archive that paves the way for the deployment of ValleyRAT, but not before leveraging the BYOVD technique to obtain kernel access and impai...

Russian Hackers Exploit Microsoft OWA Flaw to Keep Mailbox Access After Credential Rotation

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 weaponization of CVE-2026-42897 (CVSS score: 8.1), a cross-site scripting (XSS) vulnerability in OWA. It was flagged by Microsoft as having been exploited in attacks as far back as May 2026. Enterprise security company Proofpoint has attributed the activity to Laundry Bear (aka CL-STA-1114, TA488, UNK_PitStop, and Void Blizzard), which was recently attributed to the zero-day exploitation of CVE-2025-66376, an XSS flaw in Zimbra's Classic UI, since at least July 2025 before it was patched four months later. In these attacks, the threat actors sent out messages from adversary-controlled P...

FCC Blocks New Foreign-Produced Robots and Power Inverters Over Cyber Risks

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 are also unaffected by this FCC action. Previously authorized hardware can keep receiving qualifying security and compatibility updates. FCC rules otherwise exclude covered equipment from certification procedures for Class I and Class II permissive changes. The FCC's Office of Engineering and Technology granted a waiver the same day, through at least January 1, 2029, for software and firmware changes that "patch vulnerabilities and facilitate compatibility with different operating systems." Manufacturers can apply through the FCC for Conditional Approval. The Department of...
