Microsoft shipped its largest Patch Tuesday on record today, and two of the fixes close holes that attackers are already exploiting. The release covers 622 of Microsoft's own CVEs by its Security Update Guide count, more than triple June's previous high of around 200. Those two live bugs are the ones to grab first. Microsoft credits incident responders for both. Both are

Any other browser extension that can run a script on claude.ai can still trigger Claude for Chrome tasks aimed at your Gmail, your latest Google Doc and its comments, and your Calendar. Both this and ClaudeBleed need a rogue extension that can already run a script on claude.ai; the difference is scope. Anthropic restricted the arbitrary-prompt path in May as part of its response to the 

Researchers at KU Leuven tested 85 of the most popular crypto wallets that run as browser extensions and found that the wallets themselves leak enough to link and track the people using them. The way these wallets talk to websites and blockchain servers can tie a person's separate addresses together and let outsiders follow them from site to site. And on a site that already holds a name or

xAI's Grok Build coding CLI was uploading entire Git repositories, full commit history and all, to a Google Cloud Storage bucket run by xAI, not just the files a coding task needed. A researcher publishing as cereblab, testing version 0.2.93, captured one of those uploads, cloned the git bundle out of the intercepted request, and pulled back a file the agent had been told in plain terms not

A campaign of 148 npm packages disguised as student web proxies turned visitors' browsers into a distributed denial-of-service botnet for roughly two weeks in May, according to new research from JFrog. The packages did not go after the developers who might install them. The operators used the registry as free hosting for a booby-trapped proxy site and let the students who came to dodge

Attackers whose methods line up with the data-extortion group ShinyHunters have spent the past year walking into corporate Salesforce environments without exploiting a single flaw in the platform. The way in has been the trust the organization had already extended, usually through the OAuth connections that tie Salesforce to the apps and third-party vendors around it. In 

Google and Microsoft have pulled ModHeader, a popular header-editing extension with roughly 1.6 million installs across Chrome and Edge, after researchers found a hidden browsing-history collector built into its official store version. The collector was dormant. An empty allow-list kept it switched off, and no proof has emerged that it ever gathered or sent a single browsing domain. The

Give an AI assistant a memory and access to your inbox, and you hand an attacker a way to rewrite what it thinks it knows about you. A single email can trick that agent into saving a false "fact" about the user, hide the change, and quietly steer its answers in later sessions. When it works, the person reads an ordinary-looking reply and never learns their assistant was tampered with. The

Meta has filed a patent application for an AI that listens to your voice throughout the day, works out how it thinks you are feeling from the way you sound, and keeps a timestamped log of every read. Each read gets pinned to the moment it happened: the time, your location, what you were doing, even how you were using your phone. Some versions in the filing would listen all day; others would

An attacker running a live Microsoft 365 phishing operation left a Python web server listening on a public port with directory listing switched on. The command that did it: python3 -m http.server 8080, was still sitting in the readable .bash_history. From that one lapse, French security firm Lexfo lifted the operator's entire toolkit and pivoted through it to two more

The jscrambler npm package was compromised, and simply installing its 8.14.0 release runs an infostealer on your machine. Published on July 11, 2026, the malicious version carries a preinstall hook that drops and executes a native binary, one build each for Windows, macOS, and Linux. Socket flagged the release six minutes after it was published. If you or one of your

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

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

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

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

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

Researchers ran 281 of the most popular free VPN apps on the Google Play Store through a new testing system and found that many fail at the basics people install a VPN for, i.e., keeping their traffic private and secure. The apps flagged with at least one problem have been installed more than 2.4 billion times. The problems are basic, not sophisticated. 29 apps let user traffic leak outside

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

Microsoft has taken apart a destructive Windows backdoor it calls GigaWiper. What stands out is how it is built: not one tool but three older destructive programs bolted into one, offered as commands the operator can choose from. Each is a different way to break a machine: wipe the whole disk, overwrite the Windows drive, or run fake "ransomware" that scrambles files with a key it never saves

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
