The industry spent the initial months after Anthropic’s April 7 Mythos reveal focused on volume. How many new CVEs would Mythos add to an already overloaded pipeline? How quickly would the flood of AI-driven discovery overwhelm triage capabilities? How long would it take adversaries to weaponize Mythos findings at scale? Those questions were and remain valid. Yet they all stop short of

Opening a crafted XZ archive in 7-Zip could let an attacker run code on the machine. The flaw, CVE-2026-14266, is a heap-based buffer overflow in how the archiver processes XZ chunked data, and Trend Micro’s Zero Day Initiative (ZDI) detailed it on July 15. A fix shipped on June 25 in 7-Zip 26.02.

The overflow lets an attacker “execute code in the context of the current process,” per the

A solo Russian-speaking threat actor known as “bandcampro” outsourced a chunk of their operations to Google’s open-source Gemini CLI artificial intelligence (AI) and commandeered a live botnet.

The findings come from an analysis of 200 Gemini CLI session logs between March 19 and April 21, 2026, which found the threat actor using AI, among other things, to crack passwords, set up a residential

In an ironic twist, open-source artificial intelligence (AI) platform Hugging Face revealed that it was the victim of a hack perpetrated by an autonomous AI agent system.

The company said it detected and responded to the incident targeting its production infrastructure earlier last week.

“We identified unauthorized access to a limited set of internal datasets and to several credentials used by

Cybersecurity researchers have flagged a new software supply chain attack codenamed SleeperGem targeting the Ruby ecosystem after three malicious gems were published to RubyGems with the end goal of serving additional payloads.

The rogue gems are listed below –

git_credential_manager (versions 2.8.0, 2.8.1, 2.8.2, 2.8.3) – Published on July 18, 2026
Dendreo (versions 1.1.3, 1.1.4) –

F5 has shipped fixes for a critical nginx flaw that lets a remote, unauthenticated attacker trigger a heap buffer overflow in the worker process with crafted HTTP requests. CVE-2026-42533 was patched on July 15 in nginx 1.30.4 (stable) and 1.31.3 (mainline), and in NGINX Plus 37.0.3.1; anyone on an earlier build should upgrade.

Triggering it can crash or restart the worker, causing a denial of

Russian state-sponsored threat actors have been observed leveraging the infamous ClickFix strategy to trick Ukrainian targets into infecting their own machines with data-stealing malware.

According to the Computer Emergency Response Team of Ukraine (CERT-UA), the activity has been attributed to UAC-0145, a sub-cluster within Sandworm, an advanced hacking unit affiliated with GRU, Russia’s

A previously undocumented threat actor has been attributed to the exploitation of recently disclosed SonicWall Secure Mobile Access (SMA) 1000 series VPN appliances as zero-days prior their public disclosure since June 22, 2026.

Cybersecurity company Volexity is tracking the activity under the moniker UTA0533. The discovery was made following an incident response investigation earlier this

An anonymous HTTP request can run code on a WordPress site. The bug is in core, so a bare install with zero plugins is exploitable.

Every 6.9 and 7.0 site was in range until Friday, when WordPress shipped 6.9.5 and 7.0.2 and enabled what it calls forced updates through its auto-update system.

Adam Kues at Assetnote, Searchlight Cyber’s attack surface management arm, found the flaw and reported

Eleven bytes will make an unpatched OpenSSL server set aside up to 131 KB of memory for a message that never arrives. On the glibc systems Okta tested, that memory is gone until the process restarts.

OpenSSL shipped the HollowByte fix in June with no CVE, no advisory, and no changelog entry pointing at it. Okta’s Red Team, which reported the denial-of-service bug and named it, published the
