Unpatched XRING Flaw in XQUIC Lets Remote Clients Crash HTTP/3 Servers

Unpatched XRING Flaw in XQUIC Lets Remote Clients Crash HTTP/3 Servers

Jul 10, 2026 Vulnerability / Server Security
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...
Exposed Hacker Server Reveals WP-SHELLSTORM Backdooring Thousands of WordPress Sites

Exposed Hacker Server Reveals WP-SHELLSTORM Backdooring Thousands of WordPress Sites

Jul 10, 2026 Cybercrime / Website Security
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 The strongest activity hit WordPress sites running out-of-date plugins.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...
Attackers Exploit 'Ill Bloom' Vulnerability to Drain Over $5 Million From Cryptocurrency Wallets

Attackers Exploit 'Ill Bloom' Vulnerability to Drain Over $5 Million From Cryptocurrency Wallets

Jul 10, 2026 Cryptocurrency / Vulnerability
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...

ThreatsDay: Cloud Bucket Hijacking, Windows LPE Chain, Global Fraud Bust + 17 More Stories

Jul 09, 2026 Hacking News / Cybersecurity News
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 ...
Summer of Clearinghouses

Summer of Clearinghouses

Jul 09, 2026 AI Security / Application Security
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...
