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) -

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

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

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

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

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

Cybersecurity researchers have discovered a cluster of seven malicious npm packages targeting the Vite frontend tooling ecosystem as part of a software supply chain attack. The malicious package campaign, codenamed ViteVenom by Checkmarx, marks an expansion of ChainVeil, which was observed using an "unprecedented" four-tier blockchain-based command-and-control (C2) infrastructure spanning Tron,

Cybersecurity researchers have attributed the April 2026 DigiCert security incident to a threat activity cluster dubbed CylindricalCanine. Expel, which shared technical details of the event, described the threat actor as a sub-group of GoldenEyeDog (aka APT-Q-27, Dragon Breath, and Miuuti Group), a Chinese cybercrime group known for its targeting of the gambling and gaming sectors using

A Go botnet called NadMesh turned up in early July hunting exposed AI services, and the operator's own dashboard claims 3,811 unique AWS keys. A Shodan harvester keeps the scan queue stocked with ComfyUI, Ollama, n8n, Open WebUI, Langflow, and Gradio: the image generators, local model runners, and workflow builders that teams stand up fast and firewall late. The intel feed behind that counter
