Security firms ThreatBook and Imperva say attackers are targeting a critical flaw in Fastjson, Alibaba's JSON library for Java. In affected Spring Boot applications, a malicious JSON request can execute code without authentication, with the privileges of the Java process. Tracked as CVE-2026-16723, the vulnerability carries an Alibaba-assigned CVSS score of 9.0. The confirmed chain requires

Security researchers at depthfirst published working exploit code on July 24 for a GitLab flaw that GitLab patched six weeks earlier, on June 10. It runs commands as git on any self-managed 18.11.3 server that has not taken the update. Any authenticated user who can push to a project can run it. The attacker commits a crafted Jupyter notebook and opens its commit diff, which leaks a heap

For years, phishing campaigns targeting financial institutions followed the same playbook. Victims were tricked into entering usernames and passwords, attackers collected the credentials, and accounts were compromised later when an opportunity arose. That model is changing. Recent investigations into insurance-focused phishing operations reveal a more immediate approach. Instead of harvesting

Threat actors linked to the Cl0p (aka Chubby Scorpius, FIN11, Graceful Spider, and Lace Tempest) ransomware campaign are exploiting flaws in internet-exposed PTC Windmill and FlexPLM deployments as part of a new data extortion campaign. "Attackers chain a pre-authentication information disclosure in the FlexPLM WSDL endpoint with a server-side flaw in the Windchill login servlet, enabling

The operators of the DevMan ransomware-as-a-service (RaaS) scheme are maintaining a dedicated web platform that offers affiliates the ability to build payloads, oversee earnings, and manage various aspects related to victims. Swiss cybersecurity company PRODAFT is tracking the centrally administered RaaS operation under the name Funky Mantis. "The portal combined build generation, finance,

A researcher has explained how an attacker could exploit these vulnerabilities to target industrial organizations. The post Rockwell Patches Code Execution Flaws in Arena Simulation Software appeared first on SecurityWeek.

The North Korean threat actors behind the ClickFix-style campaigns that employ typosquatted Zoom and Microsoft Teams domains have been found to operate an active phishing kit to impersonate the videoconferencing platforms in social engineering campaigns designed to deliver malware. "BlueNoroff has operationalised trust abuse by combining compromised industry contacts, social engineering, wallet

Researchers H0j3n and Aniq Fakhrul published a working exploit on July 24 that lets a low-privileged Active Directory user obtain a certificate for a Domain Controller and authenticate as that machine. They codenamed the flaw Certighost. Because Domain Controller accounts carry directory replication rights, the resulting Kerberos credential can retrieve the krbtgt secret through DCSync.

Cybersecurity researchers have disclosed a critical vulnerability in OpenAI's ChatGPT Workspace Agents that could have allowed a single phishing link to stealthily build, authorize, and deploy an autonomous artificial intelligence (AI) agent inside a victim's organization. The vulnerability has been codenamed AgentForger by Zenity Labs. The issue has since been addressed by OpenAI as of June 8,

A crafted SVG submitted to Bing's image search ran commands as NT AUTHORITY\SYSTEM on Microsoft's production image-processing workers, and as root on the Linux machines in the same fleet. XBOW's testing got the same result on workers across different hosts and network ranges, so the problem sat in Bing's image tier, not on one bad machine. Microsoft issued two critical CVEs, CVE-2026-32194 and

AI agent security is moving through a familiar maturity curve: adoption, then visibility, and finally, control. But what we've collectively discovered is that enforcing least privilege for AI agents is harder than we ever imagined. This is why there are so many approaches, from prompt filtering to identity-layer access controls. Where we've collectively landed is that understanding the intent of

Industry professionals debate whether it represents a lab containment failure or an unprecedented agentic capability milestone. The post Industry Reactions to OpenAI Models Hacking Hugging Face: Feedback Friday appeared first on SecurityWeek.

Someone installed a popular AI assistant on a rented server, switched off the setting that makes it ask permission before running risky commands, and pointed it at Thailand's Ministry of Finance, which runs the country's treasury and tax collection. The agent then worked through the ministry's network on its own, checking hosts for ways to gain root access, hunting through file systems, and
