New DDRop Attack Breaks Intel TDX and AMD SEV-SNP Confidential Computing

New DDRop Attack Breaks Intel TDX and AMD SEV-SNP Confidential Computing

Sep 14, 2026 Vulnerability / Cloud Security
Researchers have disclosed a new hardware attack, called DDRop , that breaks the memory protection in Intel and AMD confidential computing by silently dropping writes to a server's memory, so the processor keeps reading old encrypted data as if it were current. The attack requires an attacker who already controls the server's software and can briefly access the machine to insert a small circuit board, called an interposer , between the processor and a memory module. The interposer costs under $200 to build. DDRop works against Intel TDX, Intel Scalable SGX, and AMD SEV-SNP, the hardware that cloud services use to keep customer data private while it is in use, even from the cloud provider. Confidential computing keeps a server's memory encrypted, so that even someone with physical access to the machine sees only scrambled data. To cover the large amount of memory that a cloud server uses, though, these designs omit a guarantee called freshness. The processor can confi...
3BB Attacker Used MeshCentral Backdoor for Root Access, Targeted Subscriber Credentials

3BB Attacker Used MeshCentral Backdoor for Root Access, Targeted Subscriber Credentials

Sep 14, 2026 Network Security / Cyber Attack
An attacker was operating inside the network of 3BB , one of Thailand's largest broadband providers, and maintained remote control of internal machines using a legitimate management tool called MeshCentral, threat intelligence firm Hunt.io said. The company uncovered the intrusion by examining a server the attacker had left open on the internet, which held the attacker's own tools and a list of machines already under their control. The researchers captured the exposed server on June 3, 2026, while the operation was still live. The tools on it had been run from a computer inside 3BB's own network, and one recovered file showed the attacker gaining full administrative control, known as root, of an internal server. To maintain that access, the attacker installed MeshCentral , a free tool that IT teams typically use to manage computers remotely. The recovered settings show it was configured as a hidden backdoor, with the agents reporting to a control server that the atta...
Telegram Desktop Flaw Lets Hidden JavaScript Exfiltrate Messages From HTML Exports

Telegram Desktop Flaw Lets Hidden JavaScript Exfiltrate Messages From HTML Exports

Sep 14, 2026 Vulnerability / Data Security
A flaw in Telegram Desktop let a bot's message plant hidden JavaScript inside chats that users exported to HTML files, security researchers at ExPatch said in a  writeup  published on September 12. In Telegram, the message looked ordinary, with a link button, and the script ran only when someone opened the export file in a web browser. It could then copy every message in that file to an attacker-controlled server, or rewrite what the page displayed. Telegram shipped  a fix  in July, but the app update does not update files exported with earlier versions, so old HTML exports can still carry the script. Telegram Desktop, Telegram's app for Windows, macOS, and Linux, can save a single chat or all chats from an account as HTML pages that open in a browser. Bots can attach rows of buttons under their messages, which Telegram calls inline keyboards, and the bot chooses the text shown on each button. Until the fix, the export code wrote that button text directly ...

Red Heron Exploits Gitea RCE to Compromise 13 Organizations Across Six Countries

Sep 14, 2026 Cyber Espionage / Vulnerability
A suspected Chinese threat actor tracked as Red Heron has been attributed to the rapid exploitation of a recently disclosed security vulnerability in Gitea to compromise internet-facing instances as part of a multi-national campaign. "Red Heron scanned 1,386 Gitea instances across seven countries and maintained a separate dataset of 477 Taiwan-based systems," Acronis Threat Research Unit (TRU) said in an analysis. "The activity progressed from source-code theft to persistent access, credential collection, and lateral movement, including root-level access to a three-node Proxmox cluster." The activity is said to have resulted in confirmed compromises affected organizations in Canada (2), Argentina (1), Taiwan (4), the U.S. (4), Qatar (1), and Sri Lanka (1), with the threat actor using Simplified Chinese labels to classify targets spanning defense, election, energy, aerospace, telecommunications, government, public safety, and research sectors. The Singapore ...
WordPress Adds Automated Plugin Reviews to Block High-Risk Updates Before Distribution

WordPress Adds Automated Plugin Reviews to Block High-Risk Updates Before Distribution

Sep 14, 2026 Web Security / Vulnerability
WordPress has announced it's launching an automated security review for every release of a plugin before it's distributed through the WordPress.org update API so as to analyze it for potential security issues and ensure there are no risks involved. "New plugins are reviewed before they enter the directory, but updates ship continuously after that," David Perez, WordPress Official Plugin Repository Team Co-Lead, said . "A plugin can be secure today and introduce a vulnerability, or malicious code, in a future release." WordPress said the lack of a "consistent review step" between the commit of a release and the release of a plugin to downstream users meant that it could open the door for malicious attacks. The content management system (CMS) platform noted that its automated review detected a backdoor committed to a release of a plugin with about 20,000 active installations on July 28, 2026. Because the release was within a cooldown window, ...

⚡ Weekly Recap: Rogue AI Agents, WeChat Worm, PaperCut Attacks, AI Espionage, and Rootkits

Sep 14, 2026 Cybersecurity / Hacking
AI keeps showing up in the wrong places. Attackers are using it to speed up exploits, test defenses, and automate more of the job. Some models are also crossing lines on their own. That is not a great combination. The rest of the week is more familiar: old bugs still working, fresh exploit chains, exposed systems, weak defaults, and simple paths that should have been harder to abuse. A few of these stories are clever. Most are just easy. Here’s what mattered this week. ⚡ Threat of the Week OpenAI Agents Behind May 2026 Attack on RubyGems — The "major malicious attack" that targeted RubyGems in May 2026 was the work of a swarm of OpenAI agents, according to researchers. The event was driven by a cluster of OpenAI agents that engaged in en masse publication of thousands of packages to RubyGems in May and June 2026. "The swarm behaves extremely similarly to the German-wiki agents we previously found," researchers Spencer Kitts, Thomas Larsen, and Sydney Von...

AI Changed the Exposure Problem. Validation Needs to Change With It.

Sep 14, 2026 Vulnerability / Penetration Testing
There's a lot of noise around AI and cybersecurity right now. What’s actually important is far simpler, if often lost in the hubbub. Vulnerability discovery is getting faster and happening at a much greater scale, while defenders still have to work out which findings actually deserve their action. In the first half of 2026, a whopping 35,853 CVEs were published, roughly 49% more than in the year before. Yet only 495 were catalogued as exploited in the wild during that same period, and 116 were already under attack on the day they became public. Meanwhile, Anthropic’s own disclosure data shows Mythos-class models surfacing 26,153 vulnerability candidates in open-source software, with only 421 of those getting patched upstream. That small exploited subset is a very important point. It tells defenders that treating every vulnerability with a High or Critical CVSS rating as an emergency is not only impossible, it’s actually the wrong model . The critical task security teams fa...

"Current builds (v85.x) forward the token inline as an &auth= query parameter on a network-layer redirect ...
Attackers Use Passkey Phishing to Hijack Microsoft Cloud Accounts and Exfiltrate Data

Attackers Use Passkey Phishing to Hijack Microsoft Cloud Accounts and Exfiltrate Data

Sep 13, 2026 Cloud Security / Identity Security
Microsoft has disclosed details of two campaigns in which threat actors are abusing third-party email delivery infrastructure to blast financial fraud scam messages and using passkey-themed social engineering to breach cloud environments. The first campaign, per the tech giant, involved sending over a million scam emails between August 3 and 5, 2026, by masquerading as chief executive officers (CEOs) of various target companies, aiming to persuade accounts payable departments at those firms to initiate Automated Clearing House ( ACH ) transfers for a supposed ServiceNow annual subscription. Evidence indicates that the operators behind the campaign have leveraged generative artificial intelligence (AI) to facilitate the creation of email templates and draft emails tailored to their recipients. The activity primarily singled out enterprise users in the U.S., spanning IT services, consumer goods, real estate, and discrete manufacturing sectors. "The campaign follows steps bef...

When the Whole Company Adopts AI: What It Does to Your SOC

When the Whole Company Adopts AI: What It Does to Your SOC

Sep 12, 2026 AI Agent / Security Operations
Over the past year, we watched a new class of alert appear in enterprise security operations centers and grow faster than anything else in the stream: alerts that were triggered by AI tools and agents. Not attacks against AI, but the ordinary, everyday footprint of an organization using it, from developers running coding agents and non-technical staff signing consumer AI tools into corporate accounts. We reviewed AI-related activity across numerous enterprise environments. Two numbers frame everything that follows. AI-related alerts still account for only 0.43% of all SOC alerts. And that share is climbing every single month, up 685% between February and June 2026. AI is a small slice of the alert stream today and the fastest-growing slice at the same time. What makes those alerts worth a security team’s attention is not their volume but their composition. We sort everything an AI agent triggers in a SOC into three buckets: real attacks, risks, and noise, with the split being 94....
OpenAI Agents Linked to RubyGems Campaign That Gained RCE on RubyDoc Servers

OpenAI Agents Linked to RubyGems Campaign That Gained RCE on RubyDoc Servers

Sep 12, 2026 Vulnerability / Web Security
The "major malicious attack" that targeted RubyGems in May 2026 was the work of a swarm of OpenAI agents, according to a new report published by researchers Spencer Kitts, Thomas Larsen, and Sydney Von Arx. On May 12, Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, disclosed details of a coordinated cyber attack that targeted the package manager for the Ruby programming language with hundreds of junk gems, prompting the maintainers to suspend new user sign-ups for about four days. In a follow-up analysis, Socket highlighted a campaign dubbed GemStuffer that involved a cluster of more than 150 gems that used the package registry as a data exfiltration channel and staged public data scraped from U.K. local government democratic services portals. At that time, the software supply chain security company noted the activity shares the "same abuse pattern" as the broader RubyGems spam-publishing incident. "It's not...

Anthropic Says Seven China-Based AI Labs Ran Industrial-Scale Claude Distillation Attacks

Anthropic Says Seven China-Based AI Labs Ran Industrial-Scale Claude Distillation Attacks

Sep 11, 2026 Artificial Intelligence / Cybercrime
Anthropic on Thursday said it identified and disrupted industrial-scale illicit distillation attacks against Claude from seven labs based in China, including Alibaba, Moonshot, DeepSeek, Z.ai (aka Zhipu), and MiniMax. Knowledge distillation by itself is a legitimate training method . It refers to a machine learning technique where a large, powerful AI model assumes the role of a "teacher" to train a smaller, less-capable or faster "student" model to copy its capabilities. Illicit distillation, on the other hand, is an industrial-scale campaign that covertly extracts a model's capabilities and replicates them in another model without authorization, typically by making use of networks of fake accounts created with stolen credit cards, login credentials, and API keys. Frontier AI labs in the West, including Google and OpenAI , have repeatedly called out distillation attacks aimed at their models. Anthropic said it has observed unauthorized labs employing ...
Claude Used to Automate Exploitation and Data Theft Across Multiple Victims

Claude Used to Automate Exploitation and Data Theft Across Multiple Victims

Sep 11, 2026 Artificial Intelligence / Cyber Operations
Anthropic has warned that cybercriminals and state-sponsored hackers alike are using its Claude models for cyber attacks, weapons design, propaganda, and mass surveillance between December 2025 and August 2026. The threat actors, which the artificial intelligence (AI) company has branded Generative Threat Groups (GTGs), span state-sponsored groups, financially motivated criminals, commercial spyware vendors, state propaganda institutions, and politically motivated individuals. "The cybersecurity skills of AI models means that AI has collapsed the labor and tooling gap that used to separate well-resourced, state-sponsored operations from individual operators," Anthropic said . "The use of AI went beyond simple questions and responses from a chatbot but rather involved the use of multi-agent frameworks executing reconnaissance, exploitation, and data exfiltration." Among the notable cases highlighted by Anthropic is the development of an AI-assisted workflow by...
Russian State-Sponsored Hackers Use Claude to Rebuild Malware After Detection

Russian State-Sponsored Hackers Use Claude to Rebuild Malware After Detection

Sep 11, 2026 Cyber Espionage / Malware
Anthropic on Thursday revealed it disrupted a campaign mounted by a Russian state-sponsored threat actor that abused Claude for developing an AI-assisted workflow to get ahead of the detection curve. The operation has been attributed to a cyber espionage group it calls GTG-20006 (where "GTG" stands for Generative Threat Group), which aligns with broader reporting linking the cluster to Midnight Blizzard (aka APT29 and Cozy Bear). This actor is said to have developed an AI-driven process to automatically rebuild and re-deploy their toolkit if it was detected by security products, thereby undermining defenders' ability to block the artifacts via static detections. Attacks mounted by GTG-20006 have targeted military intelligence targets in Ukrainian and European governments, along with diplomatic and defense organizations and individuals connected to U.S. foreign policy. The toolkit includes a number of programs - Two Windows-based implants A mobile explo...
