An anonymous reader shares a report: Security researchers from Palo Alto Networks' Unit 42 have discovered the key to getting large language model (LLM) chatbots to ignore their guardrails, and it's quite simple. You just have to ensure that your prompt uses terrible grammar and is one massive run-on sentence like this one which includes all the information before any full stop which would give the guardrails a chance to kick in before the jailbreak can take effect and guide the model into providing a "toxic" or otherwise verboten response the developers had hoped would be filtered out. The paper also offers a "logit-gap" analysis approach as a potential benchmark for protecting models against such attacks. "Our research introduces a critical concept: the refusal-affirmation logit gap," researchers Tung-Ling "Tony" Li and Hongliang Liu explained in a Unit 42 blog post. "This refers to the idea that the training process isn't actually eliminating the potential for a harmful response -- it's just making it less likely. There remains potential for an attacker to 'close the gap,' and uncover a harmful response after all."

Deforestation has killed more than half a million people in the tropics over the past two decades as a result of heat-related illness, a study has found. The Guardian: Land clearance is raising the temperature in the rainforests of the Amazon, Congo and south-east Asia because it reduces shade, diminishes rainfall and increases the risk of fire, the authors of the paper found. Deforestation is responsible for more than a third of the warming experienced by people living in the affected regions, which is on top of the effect of global climate disruption. About 345 million people across the tropics suffered from this localised, deforestation-caused warming between 2001 and 2020. For 2.6 million of them, the additional heating added 3C to their heat exposure. In many cases, this was deadly. The researchers estimated that warming due to deforestation accounted for 28,330 annual deaths over that 20-year period.

The FBI and other law enforcement and intelligence agencies around the world warned Wednesday that a Chinese-government hacking campaign that previously penetrated nine U.S. telecommunications companies has expanded into other industries and regions, striking at least 200 American organizations and 80 countries. From a report: The joint advisory was issued with the close allies in the Five Eyes English-language intelligence-sharing arrangement and also agencies from Finland, Netherlands, Poland and the Czech Republic, an unusually broad array meant to demonstrate global resolve against what intelligence officials said is a pernicious campaign that exceeds accepted norms for snooping. "The expectation of privacy here was violated, not just in the U.S., but globally," FBI Assistant Director Brett Leatherman, who heads the bureau's cyber division, told The Washington Post in an interview. Chinese hackers won deep access to major communication carriers in the U.S. and elsewhere, then extracted call records and some law enforcement directives, which allowed them to build out a map of who was calling whom and whom the U.S. suspected of spying, Leatherman said. Prominent politicians in both major U.S. parties were among the ultimate victims.

Phonemaker Nothing used professional stock photos to demonstrate its Phone 3's camera capabilities on retail demo units, according to The Verge. Five images the company presented as community-captured samples were licensed photographs from the Stills marketplace, taken with other cameras in 2023. The Verge verified EXIF data confirming one image predated the Phone 3's release. Co-founder Akis Evangelidis acknowledged the photos were placeholders intended for pre-production testing that weren't replaced before deployment to stores.

South Korea has passed a bill banning the use of mobile phones and smart devices during class hours in schools -- becoming the latest country to restrict phone use among children and teens. From a report: The law, which comes into effect from the next school year in March 2026, is the result of a bi-partisan effort to curb smartphone addiction, as more research points to its harmful effects. Lawmakers, parents and teachers argue that smartphone use is affecting students' academic performance and takes away time they could have spent studying.

Wikipedia's volunteer editors have rejected founder Jimmy Wales' proposal to use ChatGPT for article review guidance after the AI tool produced error-filled feedback when Wales tested it on a draft submission. The ChatGPT response misidentified Wikipedia policies, suggested citing non-existent sources and recommended using press releases despite explicit policy prohibitions. Editors argued automated systems producing incorrect advice would undermine Wikipedia's human-centered model. The conflict follows earlier tensions over the Wikimedia Foundation's AI experiments, including a paused AI summary feature and new policies targeting AI-generated content.

Digital resurrections of deceased individuals are emerging as the next commercial frontier in AI, with the digital afterlife industry projected to reach $80 billion within a decade. Companies developing these AI avatars are exploring revenue models ranging from interstitial advertising during conversations to data collection about users' preferences. StoryFile CEO Alex Quinn confirmed his company is exploring methods to monetize interactions between users and deceased relatives' digital replicas, including probing for consumer information during conversations. The technology has already demonstrated persuasive capabilities in legal proceedings, where an AI recreation of road rage victim Chris Pelkey delivered testimony that contributed to a maximum sentence. Current implementations operate through subscription models, though no federal regulations govern commercial applications of posthumous AI representations despite state-level protections for deceased individuals' likeness rights.
