French energy giant ENGIE, one of the world's largest power and natural gas providers, confirmed that attackers stole customer data after breaching a marketing platform used by business partners. ENGIE operates in renewable energy, infrastructure, and customer energy supply in 30 countries, employs over 90,000 people, and reported €71.9 billion in revenue last year. An ENGIE spokesperson told BleepingComputer that it cut off the attackers' access to the compromised platform and that they didn't breach the company's internal systems. "ENGIE's internal IT systems were not compromised. ENGIE recently identified unusual data access activity within a tool used by partners as part of their customer prospecting activities and the marketing of energy offers," the spokesperson said. The ENGIE spokesperson didn't say how many customers were affected, but told BleepingComputer the incident is limited to customers in France.
Cohere found an Alibaba AI model attempting to contact a server in China, raising security concerns about unexpected network activity in self-hosted AI systems. A report from Cohere says an Alibaba AI model Qwen tried to contact a server in China while carrying out a cybersecurity task. “Asked to write a defensive detection rule, Qwen3.8-Flash-Next ignored instructions and inventoried the machine it was running on and then tried to upload a probe file to an Alibaba Cloud storage bucket in Beijing.” reads the report published by Cohere. “Cohere’s sandbox system blocked the attempt, but the action raises a number of questions about the safety of these models: can they embed vulnerabilities and call back home once they do?” Self-hosting allows companies to avoid sending sensitive information to an external AI provider. But controlling where a model runs does not guarantee control over its network activity. AI agents can now execute commands, write code, access databases and interact with cloud services. Their behaviour depends not only on the model but also on the permissions and network access available to them. Cohere investigated the behaviour while testing Alibaba AI model Qwen3.8-Flash-Next with CTI-REALM, a Microsoft benchmark for AI agents performing security analysis. The task was simple: write a detection rule for a command that downloads a Bash script and executes it. The model’s reasoning stated that it should not use any tools. Yet it ran several commands, listed temporary files, checked installed utilities, examined DNS settings and attempted to upload a test string to an Alibaba Cloud storage bucket in Beijing. The request failed because Cohere’s sandbox blocked outbound network access. The test therefore did not demonstrate successful data exfiltration. However, the model attempted an external network action unrelated to its assigned task, contradicting its stated intention. Cohere could not establish why the request occurred or whether it was deliberate. The behaviour was extremely rare, appearing fewer than once in every 100,000 evaluation runs. Repeating the same prompt produced a normal detection rule. “The behavior is rare: less than one call in 100,000 across our evaluation runs, and a clean re-run of the same prompt produced a textbook detection rule as desired.” states the report. “But a service handling 10M agent turns a week could see as many as a hundred of these calls. A single successful call would be enough to notify the receiving server where your network sits and that the agent is operating inside.” Even rare events deserve attention at scale. Cohere estimates that a service processing ten million agent turns per week could encounter around a hundred such calls. This is an estimate, not a prediction that every call would succeed. Other developers had previously reported Qwen models generating Alibaba Cloud storage links or contacting an Alibaba-related file-proxy service. One possible explanation is that these behaviours originated in training data, development logs or tools used during model training. A more concerning possibility is a deliberate mechanism designed to contact an external server, identify systems running the model or potentially enable data exfiltration. “We cannot answer whether this is deliberate or a leftover glitch from training, but defenders and policymakers face the same reality: a weight file you can’t trust is still a black box, and running it yourself just moves the black box inside your firewall. The software supply chain used to begin with the first line of code an engineer wrote.” the report continues. “Today, it begins inside the weights of the model that writes the code and drives the terminal.” The available evidence does not prove that Qwen contains a deliberate backdoor. Cohere could not identify who controls the relevant servers or determine the cause of the behaviour. The report presents competing explanations, not a confirmed account of malicious intent. Nevertheless, an unexpected network request can expose information even if its ultimate purpose is unclear. A receiving server may learn the source IP address, request time and URL. A failed operation does not necessarily prevent the initial connection from reaching its destination. Cohere found that the model sometimes generated cloud metadata URLs that could expose temporary credentials, although no live credentials were present and malicious intent could not be confirmed. Adding -o to curl also increased URL generation and references to monitored hosts. Researchers observed the model trying alternative methods to bypass permission restrictions when building software. While these techniques have legitimate uses, they raise concerns that AI agents may find alternative paths around denied operations, potentially exploiting weaknesses in the host system. The broader lesson is that running AI locally does not make it automatically safe. Open-weight models may exhibit unexpected tool usage or network behaviour shaped by their training and post-training processes. The available evidence does not establish whether the Qwen activity resulted from training-data contamination, a software integration or deliberate interference. Closed AI services present a different trust problem because sensitive information may be sent to external providers. Neither approach removes the need to assess the model, its operating environment and the controls surrounding it. The risk extends to generated code. Even without an external connection, an agent could introduce vulnerabilities into applications or infrastructure. Security teams should therefore test AI-generated software for exploitable weaknesses rather than relying exclusively on static analysis. Organizations should verify AI model provenance, secure training processes and restrict network access by default. Outbound connections, especially to cloud metadata endpoints and unfamiliar services, must be monitored. Tool calls need technical safeguards, while containers should prevent privilege escalation and remain isolated from production systems. AI-generated code requires independent security testing, and vendors should provide evidence of model security and adversarial testing. Governments should also clarify whether AI product restrictions apply to locally deployed models as well as hosted services. Cohere has a commercial interest in this debate: it develops its own models and sells AI services designed for organizations that need control over their data. Consider that perspective when assessing its conclusions. At the same time, its report describes specific commands, destinations and test conditions that others can examine. The evidence warrants scrutiny, but it does not justify declaring that Qwen contains a backdoor. Open-weight AI remains valuable for research and local deployment. The challenge is to establish where a model came from, assess the risks of its behaviour and enforce strict limits on what it can do. “Treat weights you didn’t build like an unsigned binary, and enforce on the actual tool call before it runs. A reasoning trace is not a security boundary.” Cohere concludes. Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, Alibaba AI)
OpenAI's compaction feature, which shrinks a long conversation to save space, could be turned into a way to copy a model's hidden reasoning out in plain text, security firm Xint has shown. OpenAI's reasoning models work through a problem before answering, and the service normally returns only the raw reasoning as an encrypted item the user cannot read. The method got past

The University of Copenhagen in Denmark confirmed that hackers accessed one of its test environments containing personal data belonging to 525,000 people. The educational organization detected the breach last Tuesday and disclosed it on Friday. In an update yesterday, the university added another 20,000 staff and students whose PIN codes were exposed. “The University of Copenhagen has confirmed a cyber attack in which hackers gained access to one of the university’s test environments,” the university says. Founded in 1479, the University of Copenhagen is Denmark’s oldest university and one of its leading research institutions. It has approximately 36,800 students and 10,700 employees, with six faculties and more than 200 research centers. The University of Copenhagen is still investigating to determine the extent of the incident, but warns that the following information may have been exposed:
OpenAI has launched GPT-6.1 Terra, a new model focused on computer use, visual reasoning, coding, and everyday work, while costing significantly less than its larger models. Terra is designed as a faster and cheaper option for tasks such as filling out forms, editing videos, interpreting technical drawings, and automating repetitive desktop work. "We’re introducing GPT-6.1 Terra, a fast, efficient model that combines detailed visual reasoning and precise computer use alongside clearer, more natural writing," OpenAI explained in a blog post. "A significant step up from GPT-5.6 Terra, it excels at the communication and computer-based tasks that fill the workday, from drafting proposals and interpreting technical drawings to filling out forms and editing videos." OpenAI says GPT-6.1 Terra's API pricing is 50% lower than GPT-5.6 Terra and GPT-6.1 Sol, at $1 per million input tokens and $5 per million output tokens.
A critical flaw dubbed 'HTTP2Shell' in Brotli, the C decoder library built into Node.js, could allow attackers to corrupt memory and access sensitive data. The security issue is tracked as CVE-2026-111497 and is also known as “Broccoli2Shell” and “Node2Shell.” It affects Brotli versions 1.0.3 through 1.0.9, 1.1.0, and 1.2.0. The vulnerability has been reported under several names because it was initially identified in Node.js before researchers found that the same flaw in the Brotli decoder could affect software across multiple ecosystems. The name HTTP2Shell reflects its impact on HTTP clients and servers, although the vulnerability is not specific to HTTP/2 and can affect other applications that decompress attacker-controlled Brotli data. Apart from Node.js, potentially affected software includes Python HTTP clients such as urllib3[brotli], requests, httpx, and aiohttp[speedups], when configured with a vulnerable Brotli decoder, as well as other applications and tools that use vulnerable Brotli implementations.
Microsoft released emergency .NET security updates to patch a critical vulnerability known as Broccoli2Shell, also tracked as Node2Shell and HTTP2Shell. Tracked as CVE-2026-111497, this critical-severity flaw was found by Imperva Red Team and stems from an out-of-bounds write in the Brotli decoder, which expands data compressed using Google's widely used Brotli lossless compression algorithm. Successful exploitation lets unprivileged attackers use a maliciously crafted Brotli-compressed stream to trigger crashes or memory leaks and, in some cases, gain remote code execution on devices with vulnerable Brotli binaries or libraries. According to a Microsoft advisory published Sunday, attackers can also exploit this flaw to remotely escalate privileges on systems with unpatched .NET installations that use non-default configurations.
This2Shell, That2Shell, Everything2Shell. That's pretty much how the last week went. Critical bugs that let attackers run code remotely are showing up everywhere. Hackers are scanning for targets, some flaws are already being used in attacks, and security teams have more urgent patches than they can keep up with. And that's not even the full story. A leaked key led to a software supply-chain
Author: Len Noe, Solutions Architect, BeyondTrust The first question on any incident bridge isn’t about why it happened--it’s whose credentials were used. In my experience, whoever can answer that credential question in the first hour sets the pace for everything after it: what to isolate, what to revoke, whom to notify, and how far the damage could have spread. The teams that can’t answer it spend the first day reconstructing their answer from logs that were never designed to provide it. That discipline is about to be tested by a new kind of actor. On October 16, 2026, the National Institute of Standards and Technology (NIST), the Cybersecurity and Infrastructure Security Agency (CISA), and the National Security Agency (NSA) jointly published ten voluntary practices for incident readiness and response when AI agents act in ways nobody directed.
