A flaw in Git can let a malicious repository run an attacker's code on a computer that clones it recursively, together with its submodules. The Git project fixed it this week in Git 2.56.1, with matching fixes for the 2.50 through 2.55 series in 2.50.2, 2.51.3, 2.52.1, 2.53.1, 2.54.1 and 2.55.1. The flaw, tracked as CVE-2026-111760 , is an integer truncation in how Git handles its index. An extremely long path in a repository can pass Git's safety check, but Git then writes it to disk under a shorter name that an attacker can set to .git. This lets an attacker replace a submodule's .git file with a symbolic link to a folder holding malicious hooks or configuration. Hooks are programs Git runs at set points, so once Git uses that folder, the attacker's code can run. Submodules matter here because Git refuses to replace a .git folder with a symbolic link, but in a freshly cloned submodule, .git is a file. The fixed versions, listed in the Git pr...

An attacker exploited a remote code execution flaw in SGLang , an open-source inference engine, and ran code on one of NEAR AI's inference servers last Sunday. The attacker could also have seen requests being processed on that server that day, including requests sent in confidential mode, the company said earlier this week. That mode processes requests inside a trusted execution environment (TEE) designed to keep them private even from the company itself. But the TEE "does not protect against a vulnerability in the software running inside the environment," the company said. SGLang runs inside the TEE, which is how the attacker could reach requests there. That access has since been closed, but not before the attacker moved further into the company's systems. The attacker reached an internal system behind Private Chat, a product the company had already deprecated. So far, the company has confirmed that the attacker downloaded account details for about 100 users...

French software company Vates VMS has warned of a critical security vulnerability in Xen Orchestra that it said is being actively exploited in the wild. The authentication bypass flaw, which does not yet have a CVE identifier, is tracked as VSA-2026-062 . "REST cookie parsing turns authenticationToken=j:%7B%7D into {}," Vates VMS said in an alert. "REST authentication passes that object to the XO token provider without requiring a string." "The token collection treats {} as an unfiltered lookup and returns its first token; the provider authenticates as that token's owner if it is unexpired. The authenticated /rest/v0/users/me/authentication_tokens route then returns reusable login token IDs." In other words, the vulnerability can allow an attacker to bypass authentication by sending a specially crafted cookie and perform arbitrary actions with "Admin" privileges, ultimately resulting in arbitrary code execution on managed pools and ...

Three distinct threat activity clusters with shared infrastructure and malware code similarities have been observed targeting telecommunications providers, government organizations, military entities, research institutions, and critical infrastructure across Latin America, Asia, and Europe over the past year. Check Point Research is tracking the clusters under the names SilentDelivery , OceanGate , and DarkWire . Although initially assumed to be independent sets of attacks, each with its own backdoors and post-exploitation tooling, they have all been linked through a malware ecosystem called Sparrow. The entity behind the Sparrow framework has been codenamed CopperDragon , and is assessed to be a digital quartermaster developing tools for China-nexus threat actors, including FamousSparrow , Earth Estries , Tropic Trooper , UAT-9244 , and UAT-8302 . "Each cluster employed a different toolset and different initial access techniques, including compromising internet-facing inf...

Cybersecurity researchers have disclosed details of an attack that exploited two now-patched vulnerabilities in AhsayCBS to deliver a Python-based implant. The activity, observed by Huntress in early October 2026, involves the exploitation of a chain comprising CVE-2026-105133 and CVE-2026-105134 to bypass authentication and execute arbitrary commands on affected systems. Patches for the two vulnerabilities were released by Ahsay Backup in mid-October 2026. The two vulnerabilities are assessed to have been weaponized as zero-days, with the managed security platform first observing threat actors employing a smash-and-grab approach to deploy web shells and XMRig cryptocurrency miners on compromised systems. "However, this incident reflects a much larger intrusion with more patience; the operator planted shells in several places, ran two different miners, staged tunneling tools, and installed a custom implant, all on servers whose job is to hold backups," Huntress rese...

The threat actor known as Blind Eagle has resurfaced with a new campaign targeting organizations in Latin America through judicial and administrative-themed phishing lures to deliver a remote access trojan (RAT) that shares its lineage with AsyncRAT and DCRat. "The campaign uses Portuguese and Spanish lures that resemble court notifications, fiscalía notices, tutela proceedings , and administrative documents," Zenox said in a report shared with The Hacker News. Assessed to be a Spanish-speaking group and active since 2018, Blind Eagle (aka APT-C-36) has a track record of using spear-phishing lures to distribute commodity RATs like AsyncRAT, BitRAT, Lime RAT, NjRAT, Quasar RAT, and Remcos RAT. Attack chains begin with phishing emails targeting individuals who handle cases, contracts, judicial, or institutional service requests to trick them into opening a malware-laced attachment. One email containing a Colombian judicial-themed XHTML file has been identified as ...

Fireworks AI disclosed on Monday that its investigation into a security incident first reported early last month  uncovered further malicious activity, affecting account and billing information, alongside secrets, datasets, and incomplete models for a "limited set of accounts." In a notice published on October 10, 2026, the company said it detected unauthorized use of internal Fireworks credentials that allowed an unauthorized third-party to access environment variables used in evaluation jobs in a limited number of customer accounts. The activity was detected on October 6, 2026, at 9 a.m. PDT. At that time, the AI infrastructure provider said it only found evidence that environment variables, including API keys and tokens stored as secrets, were captured in certain affected accounts, adding that there were no signs that customer models, datasets, training data, inference traffic, or personal information were accessed. In response to the incident, Fireworks AI took th...

An iOS sandbox escape published on GitHub lets an app read other apps' files on iPhones running iOS 26 and 27. That puts seed phrases, private keys, and login credentials at risk of exposure to malicious apps, Binance warned today. Apple's updates for iOS 26 and 27, released yesterday, do not list a fix. A researcher who goes by forcequit ,  in collaboration with 0xjohnny ,   released the escape, called worse_query , on Sunday, a day before those updates came out. Neither the exchange nor the researcher reported any attacks or thefts involving it. The exchange told users to delete apps installed from untrusted sources, such as sideloaded or manually signed apps, and to update iOS and all their apps. No fix for the escape has been confirmed. For anyone who suspects a breach, the exchange's  security warning  advises moving funds to a new wallet created on a clean device and resetting all active login sessions. The researcher's  proof-of-concept cod...

At some point your security will fail. This isn’t pessimism. It’s not because your team and tools aren’t sophisticated enough. It’s the reason we have detections in the first place. And, it’s why once we accept that prevention has its limits, we arrive at an interdiction strategy: finding and disrupting what got in. After the alert The alert tells you something happened. However, gaining access to your network doesn’t necessarily mean attackers have stolen data or disrupted the systems they were targeting. They may need to obtain additional access, move to another machine, or further explore the network. Being able to see and understand that activity is the intervention opportunity. People naturally gravitate toward detections during product evaluations. They’re tangible, easy to compare and quantify, and address the question everyone wants an answer to: Will they catch the attack? There’s often an assumption that the rest will follow, meaning, if the detections are good, surely...

An iMessage flaw could let a remote attacker join a group chat and receive its messages, Apple said yesterday, and it released updates to fix it. The updates also fix a separate iMessage flaw that could let someone added to a group access messages sent before they joined. As of today, other updates released yesterday for the iPhone XS, XS Max and XR, the iPad (7th generation) and some Apple Watch models do not list either fix. The company's notes also do not say whether either flaw has been exploited, what an attacker would need, whether group members would see someone who joined this way, or whether every member must update to be protected. The updates that fix the iMessage flaws also fix a flaw in Google's Brotli compression library. The notes do not mention any attacks using that flaw. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added it to its Known Exploited Vulnerabilities catalog on October 27. The flaw that could let a remote attacker join ...

The Russia-aligned state-sponsored threat actor known as Turla (aka Snake) is wielding a previously undocumented cyber espionage toolset called Cereal that's used to break into victims' Microsoft Exchange servers with an aim to surreptitiously collect emails. According to an ESET report shared with The Hacker News ahead of publication, the sophisticated and modular tool is designed for long-term intelligence gathering and has been observed against two governmental entities in Kazakhstan and Romania in late 2025. "The Cereal toolset is a carefully constructed instrument for long-term, stealthy cyber espionage," the Slovakian cybersecurity company said . "It leaves little on disk, avoids external infrastructure that could be discovered and blocked, and conceals itself within legitimate Exchange processes." "The Cereal toolset demonstrates that, for Turla, Exchange servers are not just mail servers – they are durable collection points, internal e...

Four flaws that attackers could exploit without logging in were fixed today as part of SAP's monthly Security Patch Day—the vendor rates all four 10.0, the maximum CVSS score. Three are in the SAP NetWeaver application server, the software SAP systems run on, and one is in the Web Dispatcher, which receives web requests from the internet and passes them on to that server. The flaws in the Web Dispatcher and the Internet Communication Manager (ICM), which handles the server's web traffic, could allow an attacker who can reach the software over the network to run code, the vendor says. The flaw in the server's SAML 2.0 service provider, which hands off user sign-in to an identity provider, could allow an attacker to log in as any user on some systems that use SAML single sign-on. The flaw in SAP Gateway, which connects the server to other SAP systems and programs, could allow an attacker to impersonate one of the system's own servers and take unauthorized actions...

An October cyberattack on refrigeration controllers at about 700 French retail sites was carried out by a cyber unit of Iran's Islamic Revolutionary Guard Corps (IRGC), the French government said yesterday. The attackers broke into controllers on the night of October 11 and changed their defrost settings to high temperatures. That caused food losses and, in at least 15 cases, fires. The unit is called Shahid Kaveh . It is known mainly through hacktivist personas, such as CyberAveng3rs and Cyber Isnaad Front , that publicly claim some of its attacks, France says. France's Foreign Ministry plans to summon Iran's ambassador and to ask its European partners to adopt new sanctions against Iranian organizations and individuals involved in the attack. The Paris prosecutor's office opened a judicial investigation yesterday against the unit's head, the head's two deputies and anyone else identified. It has asked for international arrest warrants. The offenses u...

Anthropic on Monday released Claude Fable 5.2 and Claude Mythos 5.2 models, which it said exhibit improvements in coding, reasoning, and vision. During pre-release training, the large language models (LLMs) helped its engineers "complete otherwise-infeasible software migrations, designed three working electronic devices from scratch, solved two open problems in the physics of black holes, made substantial progress on robotics evaluations, and formalized the proof of Fermat’s Last Theorem in 30 hours." The artificial intelligence (AI) company said high-stakes risks arising from misalignment remain low, and claimed the models matched or performed better than Claude Opus 5.5, Claude Sonnet 5.5, and Claude Mythos 5.1 on most alignment measures, resistance to misuse, honesty, and factuality. "It was roughly an order of magnitude less likely than Opus 5.5 and Sonnet 5.5 to publish harmful content to public package registries without encouragement, though it still did...

Google on Monday released updates to patch nine security vulnerabilities, including one that has come under active exploitation in the wild. The high-severity vulnerability, assigned the CVE identifier CVE-2026-125350 (CVSS score: N/A), has been described as a use-after-free bug in the XML component. Use-after-free bugs typically occur when a program attempts to access a memory location after it has already been freed. Successful exploitation of these vulnerabilities could allow an attacker to achieve data corruption, program crashes, or arbitrary code execution. An anonymous security researcher has been credited with discovering and reporting the flaw on November 6, 2026. Google acknowledged it is "aware that an exploit for CVE-2026-125350 exists in the wild," but has not revealed any additional specific information related to how it's being abused in real-world attacks or who is behind them. "Access to bug details and links may be kept restricted until...

N-able said it has taken N-central Hosted Environments offline and is urging on-premises customers to shut down their servers until further notice following the public disclosure of over 30 vulnerabilities collectively tracked as Able2Shell . "As a precautionary measure, we are temporarily taking our Hosted N-central environment offline while we take the necessary actions to secure the environment and implement appropriate remediation," N-able said . "During this time, customers will be unable to access their Hosted N-central classic environment, and associated services may be unavailable. However, the Ecoverse services under N-able Login remain available and online, including Asset View, Patching, Vulnerability Management, scripting, policies and tagging." The company also said it has not observed any signs of active exploitation of these vulnerabilities, adding it's currently working on a hot fix to address them. The following services are impacted -...
