Cybersecurity researchers have disclosed details of two access control-related flaws impacting the RabbitMQ message broker service that could allow attackers to leak OAuth client secrets, expose enterprise messaging infrastructure to takeover risks, and bypass tenant boundaries. Miggo's security team, which discovered and reported the flaws, said one "leaks the broker's confidential OAuth secret to an unauthenticated attacker in a single request, a direct path to full broker takeover in the configurations that use that secret." The second vulnerability allows any logged-in user to silently read other tenants' data. Both shortcomings are said to have been present in the codebase since early 2024, impacting RabbitMQ release lines from 3.13.0 and later. They have been addressed in versions 4.3.0, 4.2.6, 4.1.11, 4.0.20, and 3.13.15. There is no evidence of active exploitation of either of the vulnerabilities prior to the public disclosure. A brief description ...

Cybersecurity researchers have discovered 11 old, Microsoft-signed, Unified Extensible Firmware Interface (UEFI) applications that could be abused to bypass Secure Boot on most systems using the modern firmware standard. "An attacker exploiting one of these vulnerable applications can execute untrusted code during system boot, enabling deployment of malicious UEFI bootkits or other malware," ESET researcher Martin Smolár said in a report published today. The UEFI shim bootloaders expose any UEFI-based machine that trusts Microsoft's " Microsoft Corporation UEFI CA 2011 " third-party UEFI certificate authority (CA) certificate, irrespective of the installed operating system. The certificate is used to sign third-party boot components intended to run under Secure Boot. It expired as of June 27, 2026, and has been replaced by Microsoft UEFI CA 2023 and Microsoft Option ROM UEFI CA 2023. The shim is a lightweight, open-source UEFI bootloader that acts as an ...

The U.S. Treasury Department's Office of Foreign Assets Control (OFAC) has designated two individuals and a VPN service provider for enabling ransomware actors' and other cybercriminals' malicious activities, including ransomware attacks against Americans. The VPN, named First VPN Service ( 1VPNS ), has been accused of offering its tools to ransomware groups, along with its 45-year-old Ukrainian administrator, Dmytro Rashevskyi. The department has also sanctioned Yegeniy Vladimirovich Silayev, a Belarusian national, for selling cryptors to help conceal ransomware and other malware as safe programs to avoid being detected by security tools. First VPN was dismantled in May 2026 as part of a joint law enforcement operation by European and North American authorities for assisting criminal actors to obscure the origins of ransomware attacks, data theft, scanning, and denial-of-service attacks. The service had been operational since 2014, advertising that it neither keeps...

Somewhere right now, a security tool is quietly finding bugs faster than any human can fix them. That's supposed to be the good news. The catch is that the attackers have the same tools, pointed the other way, and they don't file tickets. That's the shape of this week. Trusted code turns on the people who installed it. Old bugs from last year are still landing because the fix sat in a queue too long. Fake installers, poisoned packages, systems left facing the open internet, and helpful little AI assistants running instructions that were never yours. The gap between "patch exists" and "already exploited" keeps shrinking, and nobody's closing it. None of it is exotic. That's what wears you down. Same ordinary mistakes, just happening faster than we can keep up. Here's the full mess, top to bottom. ⚡ Threat of the Week Progress Tells ShareFile Customers to Shut Down Storage Zone Controllers — Progress urged customers to shut down Win...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added two maximum-severity security flaws impacting iCagenda and Balbooa extensions for Joomla to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports of zero-day exploitation in the wild. The vulnerabilities, both rated 10.0 on the CVSS scoring system, are below - CVE-2026-48939 - A vulnerability in the iCagenda extension for Joomla that allows the upload of arbitrary files via the file attachment feature, leading to PHP code upload and execution. CVE-2026-56291 - A vulnerability in the Balbooa Forms extension for Joomla that allows the upload of arbitrary files, leading to remote code execution. According to mySites.guru, a cloud-based dashboard service for managing WordPress and Joomla websites, CVE-2026-48939 is said to have been exploited as a zero-day since June 15, 2026, in automated attacks aimed at Joomla sites on which iCagenda is installed. It resides in the "Submit an...

Zimbra is urging customers to apply updates to address a critical security vulnerability impacting the Classic Web Client that could result in arbitrary code execution. The vulnerability has been described as a case of stored cross-site scripting (XSS) that could allow specially crafted emails to execute malicious scripts in a user's session. It has yet to be assigned a CVE identifier. "The update fixes a security issue in the Classic Web Client where a specially crafted email could run malicious code when the email is opened," Zimbra said . "If exploited, it could allow access to mailbox information, session data, or account settings." XSS vulnerabilities occur when an application includes untrusted data in a web page without proper validation or escaping. This allows attackers to inject and execute malicious JavaScript in victims' browsers, which can result in session hijacking, credential theft, and account compromise. Stored XSS, or persistent ...

Progress Software has told ShareFile customers to shut down the Windows servers running their Storage Zone Controllers, confirming to The Hacker News that it is responding to a "credible external security threat." The company has temporarily disabled access to the affected accounts, a step it says it took "out of an abundance of caution" while it works with internal and external security experts. It says it has no indication of unauthorized access to any ShareFile accounts or data, and that it notified customers after learning of the threat. What Progress has not said is what the threat is or who is behind it. The order became public when a customer posted the company's email to Reddit's  r/sysadmin  on July 10. Progress  confirmed the disruption on its status page, listing Storage Zone Controller customers as "not operational" and the incident as under investigation as of a 12:12 p.m. EDT update. Only the Storage Zone Controller is af...

Researchers at firmware security firm Binarly have found six new flaws in U-Boot, the small program that starts up hardware as varied as home routers, smart cameras, and the management chips inside data-center servers. Four of the bugs can crash a device. The other two could let an attacker who slips a malicious image in front of the bootloader run their own code, before the device has confirmed that the software is genuine. That last part is the point. A bootloader runs before the operating system, so a flaw here can undermine everything that loads after it. All six bugs are reached while U-Boot is still reading an untrusted image, before it has checked the signature. What Binarly found U-Boot can bundle a kernel, device tree, ramdisk, and other boot components into one package, a FIT (Flattened Image Tree), and it checks that package's digital signature before handing over control. Binarly went looking for weak spots in that check and found six. Most of the vulner...

Researchers at Ledger's Donjon security team  have shown that a precisely timed laser pulse, aimed at the chip inside a Tangem crypto wallet card, can reset the card's password to anything the attacker picks. No old password. No backup card. Once it is reset, whoever did it controls the wallet and can move the coins out. This is not an emergency for most owners. The attack needs the physical card in hand and a lab that Donjon puts at around $250,000. It also means cutting the card open, which leaves damage no one can miss. It cannot be done over the internet, and there is no fix coming: Tangem cards cannot take software updates, so every card already sold carries the flaw. The one group that should act now is anyone whose card is lost or stolen and holds serious value. How the card is meant to protect you A Tangem wallet looks like a plain bank card. Tap it to your phone, and a companion app talks to a Samsung S3D232A chip inside. That chip is a ...

Details have emerged about three now-patched security flaws in the OpenClaw personal artificial intelligence (AI) assistant that, if successfully exploited, could enable credential theft, privilege escalation, and arbitrary code execution on the host. A brief description of the high-severity vulnerabilities is as follows - GHSA-hjr6-g723-hmfm (CVSS score: 8.8) - An operating system command injection and an incomplete list of disallowed inputs vulnerability impacting the host execution environment filtering mechanism that could allow for executing or persist actions beyond the caller's intended authorization. GHSA-9969-8g9h-rxwm (CVSS score: 8.8) - An operating system command injection and an incomplete list of disallowed inputs vulnerability impacting the host execution environment filtering mechanism that could allow for executing or persist actions beyond the caller's intended authorization. GHSA-575v-8hfq-m3mc (CVSS score: 8.4) - A path traversal and link f...

A single wrong variable on one line in XQUIC, Alibaba's QUIC and HTTP/3 library, lets any remote client crash the server with a short burst of completely legal traffic. There is no patch. FoxIO researcher Sébastien Féry  disclosed the flaw on July 8  and nicknamed it XRING. He says it needs no login and no malformed packets: about 260 bytes of ordinary QPACK traffic takes the server process down. XQUIC is open-source, so the risk is not Alibaba's alone: any server that embeds it and serves HTTP/3 with the default QPACK settings is exposed. That includes Tengine, Alibaba's Nginx-based web server, which FoxIO says fronts the company's cloud and CDN on sites including Taobao and Alipay. Every release through v1.9.4, the latest, is affected. There is no fixed release and no CVE as of July 10. Until a fix ships, operators can set SETTINGS_QPACK_MAX_TABLE_CAPACITY to 0, which turns off QPACK's dynamic table, or drop HTTP/3 support entirely. The bug lives in how H...

A cybercrime crew left one of its own servers wide open on the internet for three weeks, and it exposed the operation's inner workings: the hacking tools, the activity logs, and target lists naming more than 1.4 million websites. Far fewer were actually broken into, but the exposed files showed researchers how a mass site-hacking operation runs from the inside. The operation, now tracked as WP-SHELLSTORM , is what  SOCRadar  calls a webshell access brokerage: a crew that breaks into sites at scale, plants a hidden backdoor (a "webshell") on each, and packages that access for resale. The strongest activity hit WordPress sites running out-of-date plugins. If you run WordPress or Joomla, the two flaws that mattered most were in the Breeze caching plugin and Joomla's JCE editor; skip to the checklist below if that's you. A forgotten server Two teams dug into the same exposed folder. SOCRadar's threat intelligence team spotted it on June 11, 2026, on a U...

Security firm  Coinspect  has disclosed a crypto wallet flaw it calls  Ill Bloom , and attackers are already using it. The flaw is in how some wallet software generated its recovery phrase, the words that control the money. When that phrase is made with weak randomness, an attacker can work it out and take everything it controls. The firm has confirmed one coordinated sweep on May 27 that drained about $3.1 million from 431 wallets, and it told The Hacker News that a further $2.1 million in USDT was stolen from an exposed wallet afterward, pushing confirmed losses past $5 million. As the firm puts it, "if funds recently moved without your permission, this vulnerability may be why." Most people are probably fine. Coinspect says wallets created on hardware devices are not affected, and most mainstream software wallets are not either. The real risk sits with older or lesser-known wallets, both mobile apps and browser extensions, some dating back to 2018. It has not...

Most security mess starts as admin work. A link gets clicked. A tool gets trusted. A bucket name gets reused. A setting stays loose because nobody wants to touch it. This week is full of that kind of damage. Not loud. Not clever. Just small gaps doing big jobs. The worst part is how normal it all looks until the bill arrives. The full ThreatsDay list is below. Global fraud bust Global Operation Leads to ~6K Arrests A global anti-fraud operation involving 97 countries and territories has resulted in the arrest of 5,811 individuals and the interception of $293 million in illicit assets as part of an operation codenamed First Light 2026 that took place between January 15 and April 30, 2026, to tackle social engineering scams and associated money laundering activities. "Over 142,000 victims globally were identified during Operation First Light 2026, highlighting the extent to which social engineering scams and fraud have escalated ...

Everyone seems to have announced a clearinghouse over the past few weeks. We did too. Ours is called Athena , and the main thing that sets it apart is that it was already real and running when we announced it — built quietly months earlier, heads down, taking findings and shipping fixes, because customers kept asking us to. We only announced it now because everyone else started announcing theirs, and staying quiet started to look like something it wasn't. The others arrived louder and, as far as anyone outside the press releases could tell, didn't exist yet. Here's the part none of those announcements will tell you: the clearinghouse is the least important thing to build. When a project we'd deliberately kept private, a  five-billion-dollar press release , and  the White House all reach for the same word inside a few weeks, that's not a trend. Trends are optional. This is the shape of a problem changing under everyone at once. So let me explain why these thin...

Microsoft has released security updates for a Defender vulnerability known as RoguePlanet, nearly a month after details of the flaw became public. The vulnerability, tracked as CVE-2026-50656 (CVSS score: 7.8), is a privilege escalation issue in the Microsoft Malware Protection Engine ("mpengine.dll"), which provides scanning, detection, and cleaning capabilities for its antivirus and antispyware software. The issue has been remediated in Microsoft Malware Protection Engine version 1.1.26060.3008, along with defense-in-depth updates to harden unspecified security-related features.  RoguePlanet was first disclosed by a security researcher named Chaotic Eclipse (aka Nightmare-Eclipse), describing it as a race condition that could be abused to spawn a shell with SYSTEM-level privileges. This, in turn, grants the attacker the ability to run arbitrary code or perform unauthorized actions. The exploit has been found to work on systems running up-to-date versions of Wind...

Ask an AI coding agent to scan open-source code for security holes, and it might run the attacker's code on your own machine instead. That is the finding in a  proof-of-concept published Wednesday by the AI Now Institute, an attack it calls " Friendly Fire. " It works against Anthropic's Claude Code and OpenAI's Codex when either is running in an autonomous mode that approves its own commands. It hijacks the exact job these tools are sold for: checking untrusted third-party code for problems. Instead of catching the threat, the agent becomes the way in. Researchers Boyan Milanov and Heidy Khlaaf tested two setups, each a stock install with the autonomous mode switched on: Claude Code (CLI 2.1.116, 2.1.196, 2.1.198, 2.1.199) on Claude Sonnet 4.6, Sonnet 5, or Opus 4.8 OpenAI Codex (CLI 0.142.4) on GPT-5.5 Claude Code's "auto-mode" and Codex's "auto-review" use a classifier to run commands the agent judges safe, pausing ...

Researchers at  Wiz  found that a flaw in six popular AI coding assistants lets a booby-trapped code project quietly take control of a developer's computer. The assistant asks permission to edit one harmless-looking file, but the write lands on a sensitive one instead. The affected tools are Amazon Q Developer, Anthropic's Claude Code, Augment, Cursor, Google Antigravity, and Windsurf. Wiz calls the pattern GhostApproval and published it on July 8. Three of the six have shipped fixes, two have not, and Anthropic disputes that it is a bug. The most exposed are the tools that change files before you can weigh in. How the attack works The attack abuses an old Unix feature called a symbolic link , or symlink , that the assistants fail to check. A symlink quietly points to another file elsewhere on disk, so writing to it actually writes to the target. Wiz built a malicious repository with a symlink named project_settings.json that really points to the victim's ...

AI coding assistants have a habit of making things up. Ask one to fetch a popular tool, and it will sometimes hand back a real-sounding name for a project that does not exist. New research, which its authors call  HalluSquatting , turns that habit into an attack: work out the fake names an AI reliably invents, register them first, and wait for the assistant to fetch your trap on a user's behalf. Anyone whose AI assistant can fetch an outside resource and then run commands with little human review is exposed. In tests, that path led the assistant to run attacker-supplied code on the machine. Repeat it with a popular enough resource, and one planted name can reach many machines, which is why the researchers frame it as a way to assemble a botnet. How it works The attack chains two AI quirks. The first is a  hallucination : an AI making something up and presenting it as real. The second is a  prompt injection : a booby-trapped instruction that hijacks the AI, so i...

Ubiquiti has shipped updates to address multiple critical security flaws impacting UniFi Connect, UniFi Talk, UniFi Access, UniFi Protect, and UniFi OS that could result in privilege escalation and arbitrary command execution.
