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...

The China-linked cybercrime group known as Silver Fox has been attributed to a new Rust-based remote access trojan (RAR) called MODBEACON . Chinese cybersecurity company QiAnXin said that while the threat cluster may appear like a low-sophistication, high-activity operation that propagates malware via counterfeit installers using SEO poisoning techniques, it belies their true organizational structure , which compromises multiple distributors. "These distributors conduct activities across Asia using counterfeit software installers distributed through SEO campaigns, leveraging variants of Gh0st RAT and WinOS (ValleyRAT) trojan families," QiAnXin said . One such campaign observed in mid-June 2026 involved a distributor delivering a previously undocumented modular RAT targeting technology, education, and state-owned enterprises in the country. MODBEACON's requested command-and-control (C2) infrastructure is hosted on Amazon and Cloudflare's Content Delivery Networ...

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...

Most enterprises assume their asset inventory is close enough to accurate. The evidence suggests otherwise. According to a survey of over 600 security leaders in the 2026 Axonius Actionability Report, only 45% of organizations consolidate their asset and exposure data into a single view, and every downstream security program inherits whatever the inventory gets wrong. Lumen Technologies , a telecommunications company with nearly a century of history, put this to the test. Geoff Krahn, Director of Product and Platform Security at Lumen, and his team used the Axonius asset intelligence platform to reconcile data from more than 40 disconnected systems into one trusted view. They uncovered 60 times more devices than they knew they had, then rebuilt their exposure management program on that foundation. Why asset inventories break down at enterprise scale Lumen's environment is an extreme case of a problem most security teams recognize. More than 40 independent IT and security to...

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...

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 the encrypted tunnel, including the DNS lookups that reveal which websites you visit. 61 apps send some data in plain text that anyone watching the traffic on that network can read. Five of those send the app's configuration file in the clear, which lets an attacker on the network redirect the connection to a server they control. The system, called MVPNalyzer , was presented at the NDSS security conference in February 2026 by researchers at the University of Michigan, the University of New Mexico, and IIT Delhi. It is a mobile counterpart to the same lab's earlier VPNalyzer study ...

A threat actor has been targeting organizations spanning multiple sectors with voice-based fake security requests that prompt Microsoft 365 users to enroll a new Entra passkey with an aim to carry out data extortion attacks. The threat actor, tracked by Okta under the moniker O-UNC-066 , has deployed a panel-controlled phishing kit that's capable of targeting the passkey enrollment process . The activity has singled out food and beverage, technology, healthcare, automotive, construction, and aviation industries. "The threat actor registers domains that incorporate the word passkey as part of a voice-enabled phishing ('vishing') scheme," Okta researcher Houssem Eddine Bordjiba said . "The threat actor then calls targeted users on the phone in an attempt to persuade them that they need to register a new passkey." Users are then directed to a phishing kit that's identical to the Microsoft passkey enrollment process, giving the impression that th...

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...

A 41-year-old former ransomware negotiator has been sentenced to nearly six years (i.e., 70 months) in prison in the U.S. for their role in conspiring with the now-defunct BlackCat ransomware operators to extort multiple victims and working with two other cybersecurity professionals to target additional victims in 2023. In a sentencing memorandum, federal prosecutors described Martino as a "double agent working to maximize the harm to his clients and the financial gain to cybercriminals who paid him a part of the ransom." Angelo Martino, 41, of Land O'Lakes, Florida, pleaded guilty to one-count information charging him with conspiring to interfere with interstate commerce through extortion back in April. The defendant worked as a negotiator on behalf of five different ransomware victims, while providing BlackCat attackers with confidential information regarding their negotiating position and strategy without their knowledge or permission. This information inclu...

Datadog Security Labs is warning of "several overlapping campaigns" that are systematically enumerating corporate GitHub organizations, repositories, and user accounts through the GitHub API. "Operators rely on automated scraping tooling with custom or legitimate-sounding user agents, leveraging GitHub 'ghost' accounts that are often years old, or compromised OAuth tokens and personal access tokens (PATs) from legitimate users," Julie Agnes Sparks, senior security engineer at Datadog, said . While the activity in most cases involves targeting public data, select instances have gone beyond public information enumeration to successfully clone private repositories. The campaign employs a mix of automated scanner tools, over 50 dormant accounts, and dozens of legitimate accounts that have had their personal access tokens (PATs) exposed unintentionally or compromised through some other method to facilitate the enumeration. What's notable about the ...

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. Because this is malware and not a single flaw, there is no patch to chase; GigaWiper is what an attacker runs after they are already inside, which makes early detection and clean, offline backups the real defense. The same malicious files show up in a second report under another name: BLUERABBIT , a backdoor Binary Defense flagged last month . Microsoft lists four hashes for the GigaWiper backdoor ; Binary Defense lists the same four for BLUERABBIT , and both command servers match. Binary Defense, citing Google's Threat Intelligence Group, ties the malware to a likely Ir...
