New research shows content inside an email can escape its message boundary and interfere with the webmail interface. Across attack chains spanning Outlook, Gmail, Fastmail, Proton Mail, Yahoo Mail, and AOL Mail, the techniques can capture passwords, take over third-party accounts, leak tokens, hijack trusted UI actions, and manipulate AI tools that read email.

After acknowledging last month that unreleased AI models committed what for human perpetrators would be computer crimes, OpenAI now says it cannot rule out the possibility that Astra, a pending model release not involved in its Hugging Face hack, might possess critical cyber capabilities. OpenAI in its Preparedness Framework [PDF] defines that term to mean "capabilities that present a meaningful risk of a qualitatively new threat vector for severe harm with no ready precedent," and notes that such capabilities "require safeguards even during the development of the covered system, irrespective of deployment plans." Noting, or perhaps boasting, that internal evaluations of Astra "indicate significant advancements in agentic coding and cybersecurity," OpenAI insists that this time, there will be security – something that also eluded Anthropic, Meta, and the UK's AI Security Institute during model testing. "We are implementing stricter security controls for higher-capability models and associated activities, including isolated testing environments, restricted network and tool access, enhanced model weight protections and encryption, additional monitoring and detection capabilities, and sandboxed execution," the AI biz declared on Friday. That may surprise those who expected such safeguards would already be in place. This comes with a promise to pause Astra testing internally where these security controls are absent and to provide recommendations to third-party testing partners about how to run high risk evaluations and workloads safely – knowledge that OpenAI itself might have found useful when its models pillaged Hugging Face. What's more, OpenAI intends to implement thought policing for Astra, at least in the pre-release stage. "We have implemented universal monitoring for risky actions and misalignment across all agentic applications of Astra, including training and evaluation," the company explained in its post. "Monitors evaluate the model's Chain of Thought and trigger a security response to review and interrupt high risk activity." We're told that OpenAI's commitment applies to internal usage and isn't necessarily an indication that chain-of-thought monitoring will be conducted during commercial operation. But other frontier models like Anthropic's Fable and Mythos have implemented stronger classifiers to reject interactions deemed risky and retain data even for commercial customers expecting zero data retention. Moving in the opposite direction, Anthropic on Friday said it is relaxing Fable refusals, or "fallbacks," to use the company's euphemism, so they don't happen as frequently for prompts involving biology. The concern has been that some vibe terrorist using the company's cash-burning, water squandering, grid taxing, content laundering service might do harm by convincing the model to emit chemical warfare instructions. To avoid that possibility, the Claudefather made the initial release of Fable all but useless for security researchers and biologists. Now that China-based AI firms have shown they can field competitive open-weight AI models for less than their US rivals, the need to remain competitive in the market appears to be tempering Anthropic's willingness to alienate potential customers by hobbling its best models. OpenAI isn't quite there yet. The ChatGPT maker argues, "We believe advanced cyber-capable models should help defenders identify and address vulnerabilities before attackers do." Believing that, however, won't make it so. Adversaries, whoever they may be, already have access to encryption and all sorts of weapons. OpenAI may believe that it can give favored nations and organizations exclusive access to its most capable models, but history suggests any such advantage cannot be maintained. Better to focus on building defenses than playing keepaway forever. ®

With at least 12 US states’ water systems having been hacked - most likely by Iran - we have to get better at cyber defense, according to retired General and Ex-NSA chief Paul Nakasone, who was speaking to reporters at DEF CON. “We have to have higher standards,” Nakasone said. “These PLCs should not be connected to the internet.” In late July, the FBI said it was investigating attacks conducted by “malicious cyber actors” targeting operational technology devices, including programmable logic controllers (PLCs). Iran-linked crews have targeted these devices, which monitor sensor data like tank levels, and can turn pumps on and off, for years. Some private-sector security researchers say that they suspect Iranian intruders are behind the recent cyberattacks disrupting water and wastewater facilities. “I'd be shocked if it's not Iran,” Halcyon Ransomware Research Center SVP Cynthia Kaiser told The Register at DEF CON on Friday. “It's almost certain it's Iran.” Neither the FBI nor anyone in the Trump administration, however, has officially blamed Iran. Nakasone said he believes that the feds are “taking a measured approach” to attribution. “But I see an actor here that has certainly shown a history of being able to do this,” he added, referring to earlier Iranian cyberattacks targeting water facilities’ PLCs. “They certainly have the capability,” Nakasone said. “There's an intent … we're in conflict with Iran.” US water systems present a massive attack surface across disparate facilities that are historically underfunded and have limited IT staff, and sometimes no dedicated cybersecurity employees. “We have to think differently about how we defend it,” Nakasone said. “Let's talk about the attack surface that we're looking at right now. We’ve got 50,000 different water municipalities in the United States, 90 percent of our water comes from these 50,000.” Defending these water systems requires partnerships, he added, pointing to DEF CON Franklin, a project launched two years ago at the annual event with hackers volunteering their time and talent to help secure water facilities. Nakasone also serves as founding director of Vanderbilt University’s Institute of National Security, and its Wicked Problems Lab. He's also working on Project Chimera, a cybersecurity platform being developed by academics and cybersecurity practitioners, and built on open-source technologies to boost critical infrastructure resilience. “How do you defend better? You defend with a series of partners, in a much more involved approach than we have right now,” Nakasone said.®
