Hackers Exploit JFrog Artifactory Flaws to Bypass Authentication and Gain Admin Access

Wiz Research observes multiple attackers exploiting three JFrog Artifactory flaws, including default-configuration authentication bypass CVE-2026-82329, to gain admin access and deploy backdoors.

Attackers chain CVE-2026-42018 and CVE-2026-42016 to exchange anonymous JWTs for administrator-scoped tokens, or exploit CVE-2026-82329 directly via the registry join endpoint to obtain admin privileges under default configuration. Post-exploitation observed by Wiz includes persistent admin users created within five minutes, malicious Groovy plugins for command execution, and Rust-based backdoors dropped to /tmp, /var/tmp, and /dev/shm with C2 communications. Compromise exposes software artifacts, repository credentials, CI/CD integrations, and cluster secrets, creating supply chain risks. Fixed releases include 7.111.21, 7.117.28, 7.125.20, 7.133.29, 7.146.38, and 7.161.20.

Another Artifactory CVE under attack by AI agents or humans

Attackers are actively exploiting CVE-2026-82329, a critical JFrog Artifactory authentication bypass, minting admin tokens on exposed servers days after patch release.

CVE-2026-82329 is a CVSS 9.8 unauthenticated authentication bypass in JFrog Artifactory, disclosed Friday, that allows attackers to create new administrative credentials. watchTowr's honeypots recorded exploitation from a small number of IPs within days, including enumeration of users, groups, credential sets, and federated access topologies. Researchers urge urgent patching, credential rotation, and treating exposed instances as potentially compromised to prevent build-pipeline tampering and downstream supply-chain impact.

From Hacks to Bioweapons, Claude Misuse Is Now Everywhere

Anthropic reports Claude was misused by Midnight Blizzard, ShinyHunters, disinformation campaigns, and bioweapon attempts; roundup also covers Xinbi takedown.

Anthropic's new report documents eight months of Claude misuse: Russian state-sponsored hackers (Microsoft-named Midnight Blizzard) used it for reconnaissance against Ukrainian and European government networks, stealing data and maintaining access, while ShinyHunters used it across hacking and extortion campaigns, and users attempted bioweapon development. Anthropic says it disrupted the activity. The WIRED roundup also covers the US seizure and sanctioning of Xinbi Guarantee, a Telegram black market with $30 billion-plus in sales mostly laundering pig-butchering scam proceeds, plus DOJ raids on 13 scam compounds in Madagascar and a four-year prison sentence for a Conti ransomware member. Meta faces scrutiny over AI child abuse ads and a class action over photo harvesting for AI training.

Florida says motor vehicle data breach tied to credentials stolen from officer’s personal device

ShinyHunters breached Florida's DMV using credentials stolen from a police officer's personal device; the state confirmed the breach and is investigating.

Florida's Department of Highway Safety and Motor Vehicles (FLHSMV) confirmed a data breach after ShinyHunters obtained DMV data using credentials a criminal actor took from a Plant City police officer's personal electronic device. The department learned of the breach on September 4, is investigating with the Florida Digital Service, and ShinyHunters shared a DMV record of Jeffrey Epstein as proof of access. Experts initially speculated a link to the IDScan breach of 153 million driver's licenses. Anthropic reported that suspected ShinyHunters affiliates use AI to scan credentials, map systems, and exfiltrate data, in one case moving from a stolen developer token to cloud admin access in about three hours.

Berlin investigates new data leak after hackers publish stolen login credentials

Berlin investigates a fresh leak after Rhysida hackers published stolen login credentials; the city refuses to pay the ransom demand.

Berlin confirmed hackers published additional stolen data, including login credentials, from a mid-August cyberattack on two city ministries responsible for urban development/housing and transport/climate. The Rhysida ransomware group claimed the breach in late August, saying it stole 5.79 TB of data including contracts, emails, passwords and classified information; Berlin acknowledged an extortion demand but refused to pay. Berlin's data protection regulator said the leak includes personal data on public employees and possibly residents, such as names, addresses, dates of birth and bank information. Germany's BSI separately linked the campaign to the TerminalFix fake-CAPTCHA technique and the LoremIpsumLoader/AxolotLoader malware tied to financially motivated Rhysida-associated hackers, days before Berlin's Sept. 20 election.

Mapping out your unknown: A threat hunter’s guide to GitHub

Datadog Security Labs publishes a threat-hunting guide with audit-log queries to detect GitHub token theft, device code phishing, and source code exfiltration.

Datadog's threat-hunting guide covers GitHub audit log queries for detecting compromised accounts, stolen personal access tokens, and malicious OAuth app authorizations. Attackers typically obtain credentials through phishing, credential stuffing, leaked secrets, or device code phishing, then map private repositories, exfiltrate source code, and pivot into connected cloud and CI/CD environments. The guide maps detections to MITRE techniques like T1078 and T1528 and documents GitHub logging quirks affecting attribution, token metadata, and visibility fields.

From Infostealer Log to Marketplace Listing: A Technical Walkthrough of the Credential Theft Pipeline

Cyble walkthrough maps how infostealer logs move from endpoint infection through aggregation and enrichment to dark web credential marketplace sales.

Cyble breaks the credential theft pipeline into stages: infostealer execution harvesting browser credential stores, cookies, session tokens, crypto wallets, and FTP configurations; aggregation of stealer logs via C2 panels into bundled archives; parsing and enrichment against previously leaked datasets; and final listing on dark web marketplaces. Enrichment adds employer and role context that raises prices and enables credential stuffing across reused passwords. The report advises SOC teams to monitor stealer logs and marketplace chatter early rather than waiting for breach alerts.

New AI Attack Hides Malicious Instructions in Normal-Looking Text to Evade Safety Filters

Check Point researchers show crafted prose hides policy-violating instructions that bypass all tested LLM gatekeepers, including GPT-4o mini and Llama Guard 3.

A new prompt-crafting technique embeds malicious payloads inside grammatical, natural-looking text without Base64, invisible Unicode, or obvious encodings, defeating lightweight pre-screening gatekeepers. In testing, all four evaluated gatekeeper models—gpt-4o-mini-2024-07-18, gpt-oss-safeguard:20b, claude-3-haiku-20240307, and llama-guard3:8b—classified the crafted wrappers as safe at a 100% bypass rate across 23 obfuscated prompts. GPT-5 Thinking in high-reasoning mode recovered and acted on the hidden instruction in 17 of 18 tests (~94.4%), often spending over a minute and multiple Python executions. Researchers recommend paraphrasing untrusted input, hardening gatekeeper policies, and applying defense-in-depth controls for agentic deployments.
