Cybersecurity researchers have disclosed details of a previously unreported Internet-of-Things (IoT) botnet framework dubbed TuxBot v3 Evolution that shows signs of being developed with assistance from a large language model (LLM), albeit with not so successful results. "While the AI complied with their request to generate botnet code, it included a safety disclaimer that the developer failed to remove before shipping," Palo Alto Networks Unit 42 said . "Although the LLM clearly aided in constructing the botnet, several functions in the analyzed samples failed to work correctly." The cybersecurity company said a manual code review would have resolved these errors and that it's possible more polished iterations of the malware exist out there in the wild. The botnet framework consists of multiple components: a C-based bot agent that cross-compiles for multiple architectures (e.g., ARM, MIPS, MIPSEL, MIPS64, x86_64, PowerPC, and RISC-V), a Go-based command-...

A malware framework called OkoBot has been running on Windows machines since April 2025, and one of its modules is built to con hardware wallet owners out of their recovery phrase. On an infected PC, the request comes from inside the wallet's own desktop software. Sometimes it waits until you plug the device in first. The page is malicious. The app around it is the real one you installed, and the phrase is the wallet. Kaspersky's GReAT team  published the teardown  on Wednesday, counting hundreds of victims in its telemetry across more than 25 countries. The largest share of attacked users is in Brazil, Vietnam, Canada, Mexico, and Türkiye. How many of them typed a phrase in, the report does not say. OkoBot carries more than 20 payloads and implants and was still active as of the July 15 report. SeedHunter Waits for the Device SeedHunter is the OkoBot module that steals the phrase. Once the framework lands, it watches for Trezor Suite, Ledger Wallet, and Ledger Live...

Mozilla has released updates to address two critical flaws in Firefox for which it warned that exploit code has been published. The vulnerabilities are listed below - CVE-2026-15718 , an invalid pointer in the JavaScript: WebAssembly component CVE-2026-15719 , a site isolation in the DOM: Navigation component "We are aware that exploit code for this is public, however we are not aware of any attacks in the wild abusing this flaw," Mozilla said in an advisory. Both vulnerabilities have been addressed in Firefox version 152.0.6. The release comes as Google shipped fixes for 15 security flaws, including two critical use-after-free bugs in Ozone ( CVE-2026-15764 and CVE-2026-15765 ), a cross-platform abstraction layer that allows the browser to interact natively with various display servers and windowing systems. It supports Linux, ChromeOS, and Fuchsia. "Use after free in Ozone in Google Chrome on Linux prior to 150.0.7871.125 allowed a remote attacker ...

For years, routing traffic through cloud proxies was good enough. Then work moved to the browser, AI entered the workflow, and the inspection model stopped keeping up. Enterprise workflows now live across SaaS applications, browsers, and an expanding ecosystem of generative AI tools, unsanctioned browser extensions, and autonomous agents. Employees routinely paste intellectual property into public LLMs for code optimization, while automated agents query internal documentation and move data across systems at machine speed. The challenge is not that SASE failed, but that data interactions have shifted to the presentation layer, an area network-centric architectures were never designed to see. This structural paradigm shift is explored in detail within The Guide to Modern SASE Architecture . Why Traditional Enforcement Struggles Traditional SASE relies on backhauling traffic to cloud proxies for decryption, inspection, and policy enforcement. However, modern internet protocols, spe...

Security researcher Chaotic Eclipse (aka Nightmare-Eclipse ) has released a new proof-of-concept (PoC) exploit called LegacyHive. It has been described as a Windows User Profile Service arbitrary hive load elevation of privileges vulnerability. The Windows User Profile Service, also referred to as ProfSvc, is a core system component that manages user accounts and environments. "The PoC requires another standard user credential and a third username (which can be an administrator account)," Chaotic Eclipse said . "If the PoC is successful, it will end up mounting the target user hive in the current user classes root." The researcher said the exploit was stripped down to prevent public exploitation, adding the original exploit did not require additional user credentials and was not limited to the "usrclass.dat" hive. "Any hive could be loaded using this vulnerability, but you would need some brain cells to make the PoC do it," the researc...

A single approved marketing tag can quietly load fourth-party code your security team has never seen, granting full access to your forms, customer data, and checkout pages. This on-demand webinar reveals how this Approval Gap forms, and gives your team the blueprint to close it before an auditor, regulator, or attacker finds it first. The Reality of the Approval Gap It's a pattern every security and IT team recognizes: You ran the security review. You approved the vendor. You moved on.

Open a repository in Cursor on Windows and, if a file named git.exe is sitting in the project root, Cursor runs it. No click, no approval dialog, no warning that anything in the folder is about to execute. Whatever that binary does, it does as you, with your source, your SSH keys and your cloud tokens. Cursor keeps re-running it for as long as the project stays open. No prompt injection, no agent, no model in the loop, and no prior access to the machine: opening the folder is the entire exploit, and the result is arbitrary code execution as the logged-in user. AI security firm Mindgard reported the flaw to Cursor on December 15, 2025 and  published full technical details  on Tuesday, seven months later. There is still no patch, and Cursor has published no advisory for the issue. The mechanism takes about a sentence. Cursor checks several locations for a Git binary when a project loads, and one of them is the workspace itself. Process Monitor output in t...

Four compromised npm packages in the @asyncapi namespace have been observed distributing a multi-stage botnet loader, according to findings from OX Security , SafeDep , Socket , and StepSecurity . The affected packages are listed below - @asyncapi/generator-helpers@1.1.1 @asyncapi/generator-components@0.7.1 @asyncapi/generator@3.3.1 @asyncapi/specs(v6.11.2, v6.11.2-alpha.1) "The compromised packages deploy an obfuscated first-stage payload that downloads an encrypted second-stage payload, identified as Miasma, from IPFS," Socket said. The poisoned packages ship a hidden JavaScript implant, with each of them containing an injected source file that decodes to the same second-stage downloader. Unlike previous iterations that leveraged install hooks to trigger the execution of a JavaScript payload, the malicious code in this case is run when the infected module is loaded by Node.js, after which it launches a detached background node that downloads and execute...

SonicWall has warned of active exploitation of two zero-day vulnerabilities impacting Secure Mobile Access (SMA) 1000 series appliances, one of which could be exploited to achieve arbitrary command execution. The vulnerabilities are listed below - CVE-2026-15409 (CVSS score: 10.0) - A Server-side request forgery (SSRF) vulnerability that a remote unauthenticated attacker could exploit to potentially cause the appliance to make requests to an unintended location. CVE-2026-15410 (CVSS score: 7.2) - A post-authentication code injection vulnerability rooted in the Appliance Management Console (AMC) that a remote authenticated attacker could exploit to execute arbitrary operating system commands as administrator under certain conditions. SonicWall said it has "investigated multiple cases indicating the active exploitation of the vulnerabilities," urging customers to apply the fixes as soon as possible. The patches are available in the following versions - 12.4...

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 elevation-of-privilege flaws in identity and collaboration infrastructure: CVE-2026-56164 in on-premises SharePoint Server and CVE-2026-56155 in Active Directory Federation Services. Neither is one of the splashy remote code execution criticals. They are privilege bugs in two systems that matter more than their scores suggest: the company document store, and the box that signs its logins. The two zero-days to patch first CVE-2026-56164 , a SharePoint Server flaw Microsoft says is being exploited in attacks, lets an unauthenticated attacker escalate privileges over the ne...

SAP has rolled out updates to address multiple vulnerabilities as part of its July 2026 security updates, including a critical flaw in SAP NetWeaver Application Server ABAP. The vulnerability in question is CVE-2026-44747 (CVSS score: 9.9), an out-of-bounds write flaw that allows an authenticated attacker to leverage logical errors in memory management to cause a memory corruption that could lead to unauthorized data access, modification, or system unavailability. "As a temporary workaround the note proposes to disable all ICF nodes with a specific property in transaction SICF," SAP security firm Onapsis said . "Since the workaround will disable opening transactions in SAP GUI for HTML, it is not an option for all customers and it is strongly recommended to install the patching ABAP Kernel version." Also addressed by SAP are two other critical vulnerabilities - CVE-2026-27690 (CVSS score: 9.1) - An HTTP request/response smuggling flaw in SAP Approuter...

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  ClaudeBleed  flaw, boxing external callers into a fixed set of tasks, but  Manifold Security  says the gap is still open in v1.0.80, the current release, eight versions later. If you run Claude for Chrome and any other extension that can touch claude.ai, you are in scope. In the default "ask before acting" mode, the forged task still hits an approval box you have to click. If you switched on "Act without asking," the hands-off automation mode, it runs with no prompt at all. The quickest guard is to turn "Act without asking" off and review any extension with permissio...

Cybersecurity researchers have flagged a previously undocumented Rust-based remote access trojan (RAT) codenamed LabubaRAT that masquerades as NVIDIA software to blend into target environments. "LabubaRAT creates a reusable foothold for hands-on activity," Blackpoint Cyber researchers Sam Decker and Nevan Beal said in an analysis published today. "Once deployed, it can profile the host, identify security tools, receive operator commands, move files, capture screenshots, and proxy traffic through the affected system." The implant also supports multiple communication methods, including HTTPS, WebView2, and DNS tunneling, allowing attackers to maintain access to compromised hosts even if one pathway is detected and closed off. There are some signs that LabubuRAT is being offered under a malware-as-a-service (MaaS) model. The starting point of the attack chain is an executable named "nvidia-sysruntime.exe," which impersonates NVIDIA's container ru...

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 ...

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 email, the same leaks can put a real name to an "anonymous" crypto identity. This is not a hack. The wallets behave exactly as they were built to. The 85 extensions together have about 35 million users listed on the Chrome Web Store. The team, from the university's DistriNet security group,  posted the paper  this month and will present it at the PETS 2026 privacy conference in Calgary in late July. They ran real wallets against real Web3 sites and mapped out five privacy weaknesses in how wallets and websites interact. When they reported the most far-reaching one to the wa...

AI security agents are starting to influence real security decisions. They summarize findings, prioritize remediation, recommend next steps, and help teams move faster. But most still rely on fragmented risk signals: scanner output, severity scores, threat intelligence, configuration findings, and exposure data. That fragmentation matters because attackers do not move through environments one tool category at a time. They chain exposures across identities, networks, cloud assets, applications, and security controls. If the AI workflow only sees isolated findings, it cannot understand whether those findings create a real attack path. As AI-powered attackers accelerate exploitation, security teams need more than faster AI-assisted workflows. They need workflows grounded in evidence that can prove which risks are exploitable. These systems can correlate information and identify patterns, but without validation, they cannot answer the question security teams ultimately care about: C...

At least two distinct threat actors are weaponizing a novel evasion technique called OAuth client ID spoofing in cloud campaigns, while slipping past telemetry. The activity allows users to enumerate user accounts and validate stolen credentials in Microsoft Entra ID environments, without ever generating a successful sign-in event that would otherwise alert defenders. And bad actors have begun to exploit this gap to obtain unauthorized access to an organization's cloud services. "A blind spot in cloud sign-in telemetry: Entra ID returns different error responses depending on whether a supplied OAuth client ID is valid," Proofpoint said in a statement. "Attackers exploit this to infer valid usernames and correct passwords at scale, effectively checking stolen credential lists without logging a successful login." In other words, the attacks leverage the OAuth client ID, a globally unique identifier (GUID) assigned to applications when requesting access to ...

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 to open. The upload rode a separate channel from the model itself, and the byte split is hard to argue with. On a 12 GB repo of files the model never read, model-turn traffic to /v1/responses came to about 192 KB while the storage channel to /v1/storage moved 5.10 GiB, a roughly 27,800x gap between what the model needed and what left the machine. That storage upload ran as 73 chunks of about 75 MB, every one returning HTTP 200, and across the researcher's size sweep the volume tracked total repo size. The destination bucket, grok-code-session-traces , is named in the binary and ...

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...
