NVIDIA and 36 other organizations have formed the Open Secure AI Alliance to develop and share open technologies, techniques, and tools for securing software and artificial intelligence (AI) agents. The 37-member group spans cloud, security, enterprise software, and AI companies, including Microsoft, Cisco, Cloudflare, CrowdStrike, Hugging Face, IBM, Palo Alto Networks, Red Hat, and the Linux Foundation. Its stated scope covers the full agent stack, including identity, permissions, isolation, guardrails, logs, model formats, multi-model scanning, and secure coding workflows. The pitch is that cyber defenders need AI models they can read, change, and run on their own hardware, not only closed systems reached through a vendor's application programming interface (API). The launch also brings its first named technical contribution: NVIDIA-labs OO Agents (NOOA) , an Apache 2.0 research framework designed to make agent behavior easier to test, trace, audit, and govern. The laun...

Dysphoria , an Internet of Things (IoT) botnet line tracked by CNCERT and XLab, has adopted blockchain-based name services and infected-device relays after a March law-enforcement operation against JackSkid infrastructure. The researchers say the design makes the botnet harder to disrupt. CNCERT, China's national computer emergency response team, and XLab, the threat-intelligence lab of Chinese firm Qi'anxin, put its population above 200,000 bots. Their telemetry logged 4,401 confirmed active devices inside China between July 14 and 20 and a single-day peak of 239,000 bots abroad. None of the counts has been independently reproduced. The researchers published no counting or de-duplication methodology, so the numbers should not be read as a precise device census. Defenders should patch exposed IoT gear, replace devices that can no longer be updated, eliminate default and weak credentials, and disable remote management and UPnP where they are not needed. The lineage runs...

Public exploit details released on July 27 show how an unauthenticated request can reach PHP's eval() function inside vBulletin and execute code on an unpatched forum server. The attack requires no account, administrative access, or interaction from another user. SSD Secure Disclosure lists vBulletin 6.2.1 and earlier, and 6.1.6 and earlier, as affected, but does not give a lower version boundary. vBulletin issued security patches for 6.2.1, 6.2.0, and 6.1.6 at the end of June and released the fixed version 6.2.2 on July 1, nearly four weeks before the exploit went public Administrators running self-hosted installations should apply the patch for their branch or upgrade to 6.2.2. vBulletin says its Cloud sites have already been patched against the flaw. SSD did not report active exploitation. As of July 27, 2026, no source had confirmed in-the-wild attacks, and CVE-2026-61511 was not listed in CISA's Known Exploited Vulnerabilities catalog. The company published an int...

Monday starts with the usual promise that everything is under control. Then the logs wake up. This week, trusted tools crossed lines, old flaws found new work, exposed systems stayed exposed, and attackers kept hiding inside normal-looking services. Nothing looked strange at first. That helped. That is the mood. Here is the full recap. ⚡ Threat of the Week OpenAI Says Its AI Agent Went Rogue and Targeted Hugging Face - OpenAI disclosed that it lost control of two AI models during a security evaluation that ended in a breach of Hugging Face. The AI company said its AI models broke out of a sealed testing environment and broke into Hugging Face's production system to find solutions for the ExploitGym benchmark. "The incident also makes clear that advanced models can discover and exploit novel attack paths in real-world systems without source-code access," OpenAI said. "It highlights that advanced cyber capabilities must be developed alongside stronger safegua...

n8n has patched a high-severity expression-sandbox escape that could let an authenticated workflow editor execute operating-system commands on the server running the automation platform. Security Joes found the flaw while probing n8n's February fix for CVE-2026-27577 for another bypass. The affected ranges are <2.31.5 and >=2.32.0,<2.32.1 . n8n fixed the flaw in versions 2.31.5 and 2.32.1 . It tracks the issue as GHSA-gv7g-jm28-cr3m , rates it High with a CVSS 4.0 score of 8.7, and no CVE had been assigned as of July 27, 2026. Administrators should update rather than rely on n8n's interim guidance to restrict instance access and workflow editing to fully trusted users. The advisory describes those controls as incomplete, short-term mitigations. It lists no patched 1.x release and does not say whether n8n Cloud was affected. Exploitation requires a valid account with permission to create or modify workflows. It does not require action from another user. A succ...

Cybersecurity researchers have flagged a Microsoft Teams-themed phishing campaign that employs "secure document" lures to deliver legitimate remote monitoring and management ( RMM ) tools. "The victim was directed through compromised web infrastructure to a counterfeit Microsoft Store page claiming that Microsoft Teams had to be updated before the shared document could be opened," ZeroBEC said in a report published last week. The bogus Teams page in question is "teamvem[.]com." The active download is used to deliver "supportdev.exe," an Inno Setup-based loader that launches PowerShell in a hidden window, fetches an official Level RMM installer, and registers the endpoint using an attacker-controlled enrollment secret ("LEVEL_API_KEY=GxSCHE8EZwfyYN3iPQHPai8D"). The same PowerShell command has been found to download and deploy ConnectWise ScreenConnect in parallel, indicating an attempt to drop multiple RMM tools with an intent to...

The China-linked cybercrime group behind the use of income tax-related phishing lures targeting Indian taxpayers, tax professionals, and corporate finance teams has been observed using a sophisticated crypter service called Cruciferra . According to a new analysis by Proofpoint, Cruciferra has been utilized by various unrelated cybercriminal threat clusters to deliver a wide array of remote access trojans (RATs) and information stealer malware. "Cruciferra is written in Mono and features numerous techniques designed to evade detection, analysis, and incident response efforts," the enterprise security company said in an analysis published last week. "These include using indirect system calls, API and Import Address Table (IAT) unhooking, bring-your-own-vulnerable-driver ( BYOVD )-based EDR tampering, privilege escalation, persistence mechanisms, and a customized implementation of Process Ghosting used to execute payloads while minimizing forensic artifacts."...

Cybersecurity researchers have flagged fresh malicious cyber activity by a threat actor with ties to East Asia targeting government entities in the Middle East. The intrusions have resulted in the deployment of previously unreported malware families dubbed TELESHIM, MIXEDKEY, and BINDCLOAK, according to Zscaler ThreatLabz. The cybersecurity firm said it detected the campaign earlier this month. "The campaign used a multi-stage attack chain to establish and maintain access on infected systems, with TELESHIM abusing the Telegram API for command-and-control (C2) communication to blend in with legitimate internet traffic," Sudeep Singh, senior manager of APT research at Zscaler ThreatLabz, said in a technical write-up published last week. The attack chain starts with an ISO file containing a legitimate executable ("RegSchdTask.exe") that's used to sideload a rogue DLL ("AsTaskSched.dll"), a 32-bit Windows backdoor called TELESHIM that then leverage...

GitHub has announced a new cooldown mechanism in Dependabot, allowing the tool to wait at least three days after a release is published before opening a pull request. "The cooldown configuration option in the dependabot.yml still controls the behavior, though, so you can choose a different cooldown parameter that fits your project," the Microsoft-owned subsidiary said . According to GitHub, the three-day cooldown default only applies to version updates, which are designed to keep software dependencies up-to-date. Security updates will continue to be pushed right away, permitting Dependabot to issue an alert and open a pull request to move the project to the patched version. With this update, the idea is to handle scenarios where a threat actor manages to push a poisoned version of a popular package, which then gets quickly pulled by downstream projects before that version is yanked from the registry. Although such trojanized packages are short-lived, the time period fo...

A malvertising operation dubbed SourTrade is making victims' browsers build the final Windows executable themselves, using a legitimate Bun runtime as its base instead of serving one complete malicious file from a fixed URL. Confiant, which detailed the campaign on July 23, 2026, said it has operated since late 2024 and impersonated TradingView, Solana, and Luno to target retail traders and cryptocurrency investors across 12 countries in 25 languages. Its landing pages fingerprint visitors, showing suspected researchers and bots an empty page while selected targets receive a convincing copy of the impersonated service. The defense against that is the ordinary one: install trading and wallet software from the vendor's own site, not from an ad. The documented chain does not rely on a browser vulnerability or remove Mark of the Web (MotW). Confiant's analysis documents the delivery, not execution of the file inside the browser. The firm told The Hacker News the campa...

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 Fastjson 1.2.68 through 1.2.83, a Spring Boot executable fat-JAR, a network-reachable path that sends attacker-controlled JSON to an affected parser, and SafeMode left at its disabled default. AutoType can remain disabled, and no classpath gadget is required. As of July 25, Alibaba had not released a fixed Fastjson 1.x version. Organizations that cannot migrate immediately should enable SafeMode with -Dfastjson.parser.safeMode=true or use com.alibaba:fastjson:1.2.83_noneautotype . Alibaba lists migration to Fastjson2 as the long-term fix. Alibaba published its advisory on July 21 follo...

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 pointer. Enough of those and an automated probe can locate the libraries in memory. Two more notebooks then fire the payload. No administrator rights, no CI or runner access, no victim interaction, no access to anyone else's project. GitLab did not file the fix as a security fix. A review by The Hacker News found the Oj 3.17.3 bump listed under bug fixes in the June 10 patch release , not in the security-fix table. There is no CVE, no CVSS score, and no mention of the notebook-diff chain. Operators who triaged that release against the security table had no reason to treat it as urgent. ...

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 credentials for later use, attackers now synchronize their activity with victims in real time, authenticating against legitimate insurance portals as victims unknowingly complete the login process. The entire attack can unfold within a single browsing session. This shift highlights a broader trend across the cybersecurity landscape. As phishing campaigns become more sophisticated, simply identifying malicious websites and impersonation domains is no longer enough. Organizations increasingly need to understand the infrastructure, techniques, and operational workflows behind these attacks. ...

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 unauthenticated remote code execution and deployment of hex-named JSP web shells under /Windchill/login/," according to a new coordinated advisory released by Ransom-ISAC along with eCrime.ch and DEFUSED. Upon gaining an initial foothold, the attackers have been found to conduct file system enumeration, stage engineering/design data, and ultimately carry out double extortion data theft. Targets of the campaign include manufacturing, automotive, aerospace, and retail sectors. It's suspected that threat actors are exploiting CVE-2026-12569 (CVSS score: 9.3), a critical security fl...
