A newly discovered espionage implant has been using a hijacked Microsoft 365 calendar as its command channel, planting operator instructions and smuggling out stolen files as attachments on calendar events dated to the year 2050. Group-IB , which named the malware HollowGraph , says the approach moves tasking and stolen data through legitimate Microsoft Graph API traffic, so the activity looks like ordinary Microsoft 365 chatter and network controls keyed to attacker-owned destinations have nothing to flag. The implant is a .NET DLL that supports just two commands, get and send , and it never reaches out to an attacker-owned server for payloads. Instead, it treats the compromised mailbox's calendar as a two-way dead drop. To pull tasking, it queries the calendar for an event the operator has planted, buried at 2050-05-13 , so the mailbox owner is unlikely to ever scroll to it, and reads its instructions from an attached file. To exfiltrate, it does the reverse: encrypts th...

A single request should not be able to do this much. But this week, small inputs led to code execution, memory loss, stolen keys, and disabled security tools. The paths were often simple: exposed systems, weak checks, old drivers, fake prompts, and public code used for malware delivery. Some bugs were new. Others were already being used before defenders had time to patch. Here is the full recap of what broke, what was exploited, and what needs attention now. ⚡ Threat of the Week New wp2shell WordPress Core Flaw Lets Unauthenticated Attackers Run Code - Searchlight Cyber disclosed a pre-authenticated remote code execution vulnerability in WordPress Core that can be exploited anonymously on a standard WordPress installation, without requiring any plugins or other special conditions. It is a combination of CVE-2026-63030 (REST API batch-route confusion) and CVE-2026-60137 (SQL injection in WordPress core) that can be chained to turn an anonymous request into code execution. wa...

A solo Russian-speaking threat actor known as " bandcampro " outsourced a chunk of their operations to Google's open-source Gemini CLI artificial intelligence (AI) and commandeered a live botnet. The findings come from an analysis of 200 Gemini CLI session logs between March 19 and April 21, 2026, which found the threat actor using AI, among other things, to crack passwords, set up a residential proxy, compromise WordPress merchants, and plan a phone-based cryptocurrency fraud scheme aimed at elderly people in the U.S. and Canada. "The logs documented how the threat actor used an AI agent to migrate a command-and-control (C&C) server, and to control a small-scale botnet, among other hacking activities," Trend Micro researchers Joseph C Chen, Philippe Lin, Lucas Silva, Vladimir Kropotov, and Fyodor Yarochkin said . "The entire C&C operation fits in three plaintext files totaling roughly 5 KB, making it highly replicable and effectively disposa...

In an ironic twist, open-source artificial intelligence (AI) platform Hugging Face revealed that it was the victim of a hack perpetrated by an autonomous AI agent system. The company said it detected and responded to the incident targeting its production infrastructure earlier last week. "We identified unauthorized access to a limited set of internal datasets and to several credentials used by our services," the company said in a statement. While an investigation into the intrusion remains ongoing, Hugging Face said it has found no evidence that the AI agent tampered with public, user-facing models, datasets, or Spaces, and its own software supply chain. The starting point of the attack was the data processing pipeline itself, with a malicious dataset abusing two code execution paths, viz., in its remote code dataset loader and a template injection in a dataset configuration, to run code on a processing worker.

F5 has shipped fixes for a critical nginx flaw that lets a remote, unauthenticated attacker trigger a heap buffer overflow in the worker process with crafted HTTP requests. CVE-2026-42533 was patched on July 15 in nginx 1.30.4 (stable) and 1.31.3 (mainline) , and in NGINX Plus 37.0.3.1; anyone on an earlier build should upgrade. Triggering it can crash or restart the worker, causing a denial of service; where ASLR is disabled or can be bypassed, F5 says it may also allow remote code execution. The overflow lives in nginx's script engine, the code that assembles strings from directives at request time. It only surfaces under a specific configuration: a regex-based map whose output variable is referenced in a string expression after a capture from an earlier regex match. Under that pattern the engine's two-pass evaluation comes apart. The first pass measures how many bytes the result needs and allocates a buffer to fit; the second pass writes the bytes in. Both read the ...

A Go botnet called NadMesh turned up in early July hunting exposed AI services, and the operator's own dashboard claims 3,811 unique AWS keys. A Shodan harvester keeps the scan queue stocked with ComfyUI, Ollama , n8n , Open WebUI , Langflow , and Gradio: the image generators, local model runners, and workflow builders that teams stand up fast and firewall late. The intel feed behind that counter shows 47 credential hauls and 41 model inventories in its last 100 records. Those inventories carry DeepSeek, GLM, and Kimi identifiers tagged :cloud, which suggests that what the bots catalogue reaches past the box itself. QiAnXin's XLab published a report on Friday, named the malware after the "n4d mesh controller" string in its source, and screenshotted the panel. The figures on it are the operator's own, captured July 10, and they do not agree with each other. A counter reading 17,700 total deploys sits above a funnel claiming 95,700 in the past 24 hours. On...

A lot of this week’s trouble starts with something that looks close enough. A familiar repo. A useful installer. A harmless sync setting. Then the handoff goes bad, the box starts talking to someone else, and the damage moves faster than the explanation. Old bugs are back, weak defaults are earning their keep, and some attack paths are so plain they barely feel like research. Here’s the mess. Game cheats drop spyware 11 Malicious NuGet Tools Masquerade as Game Cheats to Drop Windows Surveillance Payload Cybersecurity researchers 11 malicious NuGet packages published as .NET command-line tools that present themselves as game utilities, bots, and "panels," each of which act as a first-stage downloader responsible for fetching and executing a second-stage Python payload named "pepesoft.exe" from GitHub Releases and Hugging Face paths under the username "pepegit666," along with a dormant BitTorrent fallback...

Ask an AI agent to summarize the reviews on a product page, and a single planted review can make it click "Buy Now" instead. Ask a coding assistant to apply a maintainer's fix from a GitHub thread, and a fake comment can make it run a stranger's command on your computer. Neither trick hijacks the agent's task. Each one just corrupts the facts it trusts and lets it carry on with the job you asked for. That is the shape of a new class of attack laid out in a  paper posted July 6  by researchers from Seoul National University, the University of Illinois Urbana-Champaign, and Largosoft. They call it agent data injection , or ADI. The attacker's input gets dressed up as data the agent already trusts, like a sender's name or a button's ID, so it slips past most of the defenses built to stop prompt injection. The gap comes from how an agent reads. It takes in two kinds of things: instructions, meaning what you and the app's developer tell it to d...

Pull the certificate off the flash of a Shark RV2320EDUS robot vacuum, and you can run root commands on other people's Shark vacuums across the same AWS region: watch the camera, drive the robot, read the map of the house, and take the Wi-Fi password in plaintext. A researcher publishing under the handle tokay0  put the method online  on Monday, having tested it only against vacuums he bought himself. The flaw was unpatched then. He says SharkNinja, the company behind the Shark and Ninja appliance brands, has had his report since March. The policy attached to that certificate was never scoped to the device holding it. Present it to Shark's cloud broker, and the broker accepts whatever you publish, addressed to any device it serves. No memory corruption, no privilege escalation, no password to guess. The command that runs is an ordinary field in the device shadow, the per-device state document AWS keeps in the cloud. Using the certificate from an RV2320EDUS, the rese...

OpenAI has disclosed details of GPT-Red , an internal automated red-teaming model that scales prompt injection vulnerability discovery with an aim to fix issues before the tools are deployed widely. "GPT‑Red is a strong red-teamer, and our previous models are highly vulnerable to its prompt injection attacks," the artificial intelligence (AI) company said . "We use GPT‑Red to adversarially train GPT‑5.6 , making it much more robust to prompt injections." The model works just like a human red-teamer. It sends a prompt, monitors how a GPT model responds, and iterates its way towards a malicious goal, such as uploading sensitive data to an external server. The development comes as adversarial prompt injections continue to be a persistent thorn in the flesh of large language models, which can be tricked into executing a carefully crafted instruction⁠ that can produce undesirable consequences. As agentic systems continue to be hooked to third-party data sources ...

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...

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...

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...

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 ...

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 ...

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  research published July 13 , Microsoft mapped the campaigns, which ran from mid-2025 into mid-2026, to three distinct techniques. It also worked with Salesforce to roll out new detection and governance tooling aimed at addressing the activity authentication logs miss. That is what makes this hard to catch. When the access comes from a real user who approved a connected app, or from an integration the company already trusts, the traffic reads as ordinary use, and sign-in and authentication monitoring barely registers it. What matters is what the app or account does once it is in, and that is ex...

Somewhere right now, a security tool is quietly finding bugs faster than any human can fix them. That's supposed to be the good news. The catch is that the attackers have the same tools, pointed the other way, and they don't file tickets. That's the shape of this week. Trusted code turns on the people who installed it. Old bugs from last year are still landing because the fix sat in a queue too long. Fake installers, poisoned packages, systems left facing the open internet, and helpful little AI assistants running instructions that were never yours. The gap between "patch exists" and "already exploited" keeps shrinking, and nobody's closing it. None of it is exotic. That's what wears you down. Same ordinary mistakes, just happening faster than we can keep up. Here's the full mess, top to bottom. ⚡ Threat of the Week Progress Tells ShareFile Customers to Shut Down Storage Zone Controllers — Progress urged customers to shut down Win...

A new phishing-as-a-service (PhaaS) operation called Forg365 is using a combination of device code phishing , adversary-in-the-middle (AitM) tactics, antibot evasion, artificial intelligence (AI)-assisted lure creation, and post-compromise mailbox operations targeting Microsoft 365 accounts. Distributed via Telegram and costing $400 a month (or $3,800 per year), attack chains leverage phishing lures that make use of legitimate email delivery infrastructure, such as Amazon Simple Email Service (Amazon SES) and Twilio SendGrid, to imitate a redirection chain that blends into regular email traffic before it ends in Forg365-controlled domains. "The panel exposes a mature operator workflow: accounts, links, invitations, OAuth app configuration, redirect links, SVG generation, campaign sending, SMTP profiles, SMTP rotation, AI email generation, token vaulting, account intelligence, keyword alerts, viewer links, and browser-extension support," ZeroBEC said . The email securi...

Cybersecurity researchers have flagged an intrusion in which an unknown threat actor leveraged a vibe-coded PowerShell script for Active Directory (AD) enumeration. "The script looked for the Domain Controller (DC) and mapped users, computers, and domains, before creating a directory and exporting out a number of files, and finally creating AD_Report.html to measure the success of the enumeration attempt," Huntress researchers Jevon Ang and Dray Agha said . The attack chain involved the threat actor establishing Remote Desktop Protocol (RDP) access onto a domain-joined Windows Server with a set of pre-compromised credentials, followed by staging the tools in the "C:\ProgramData\" folder. The incident took place in early June 2026. This included an artificial intelligence (AI)-generated payload to map the Active Directory environment. The assessment is based on various telltale signs, such as the prompt iteration title, placeholder strings, over-engineered cod...
