⚠️ Seven malicious npm packages are targeting Vite developers.

They stay quiet during installation. Import one, and it starts a RAT delivery chain that can steal credentials, exfiltrate files, and open a reverse shell.

The attacker stores the delivery path in public blockchain transactions.

🛑 URGENT - A single anonymous HTTP request can run code on an unpatched #WordPress 6.9 or 7.0 site, even on a default install with zero plugins.

The new wp2shell flaw sits in core and still has no CVE for scanners to match.

Affected releases and mitigations 🠖 https://thehackernews.com/2026/07/new-wp2shell-wordpress-core-flaw-lets.html

⚡ UPDATE: #wp2shell now has two CVEs, and a working proof-of-concept is public.

> CVE-2026-63030 breaks REST batch routing
> CVE-2026-60137 injects SQL

Chained, they give an anonymous attacker code execution on affected WordPress sites.

⚠️ Russian state-backed hackers are using fake CAPTCHA checks to trick Ukrainian targets into running malware on their own Windows systems.

The same campaign also uses fake security apps to backdoor #Android devices.

🛑 Hugging Face, the world’s largest AI model repository, says an autonomous AI agent breached its production systems through a malicious dataset.

It accessed internal data and service credentials, then moved across several clusters through thousands of actions in short-lived sandboxes.

🚨 ALERT: A newly disclosed 7-Zip vulnerability could let attackers run code when a user opens a crafted XZ archive.

CVE-2026-14266 is a high-severity heap overflow in the XZ decoder. The code runs with the same privileges as 7-Zip.

Details: https://thehackernews.com/2026/07/new-7-zip-vulnerability-could-let.html

UPDATE: OpenSSL told THN that it views HollowByte as a server configuration issue, not a protocol flaw.

But key questions remain: whether the shipped fix improves glibc’s memory behavior and whether extended-support branches received the fix.

Okta still advises users running affected versions to upgrade.

Attackers can move in 29 minutes. High and critical application flaws take 55 days on average to fix.

The real problem is not how many vulnerabilities AI finds. It is how long those vulnerabilities stay exposed.

AI agents are inheriting long-lived secrets, broad access, and accounts that nobody properly manages.

Compromise one, and an attacker gains an identity that can call tools, chain actions, and move through systems at machine speed.

Why securing AI agents starts with privilege, not the model: https://thehackernews.com/expert-insights/2026/07/the-new-insider-has-no-pulse-securing.html

🚨 This malware hides in Microsoft 365 calendar events dated to 2050.

You would never scroll that far.
HollowGraph counts on it.

The calendar carries attacker commands and stolen files through normal Graph traffic.
