Jailbreaks bypass AI safeguards, creating security risks such as prompt injection, data exposure, and unsafe or unauthorized model behavior.
Search across headline titles and summaries.
Background for this topic.
Jailbreaking means bypassing restrictions imposed by a device, operating system, application, or AI model. On mobile devices, it can grant elevated privileges and enable software or system changes outside official controls. In AI security, a jailbreak is a prompt or technique intended to circumvent a model’s safety or policy constraints and elicit disallowed behavior or content.
The security impact depends on the target. A jailbroken device may weaken code-signing, sandboxing, update, or access-control protections, increasing exposure to malicious software and making it harder for enterprise management tools to enforce policy; organizations commonly detect and block such devices from accessing sensitive services. AI jailbreaks can expose hidden instructions, sensitive data included in prompts or context, or unsafe capabilities, so testing should cover adversarial prompts, enforce authorization outside the model, and avoid treating model refusals as a security boundary.

The new classifier in Fable 5 blocks the jailbreak technique that prompted the US export controls “in over 99% of cases”
Anthropic is putting Claude Fable 5 back online worldwide. On June 30, the U.S. Commerce Department lifted the export controls it had imposed on Fable and its more tightly controlled sibling Mythos 5 about two and a half weeks earlier
According to the one person who actually read the research paper
Dozens of practitioners said the decision to place export controls on the foreign use of Fable are misguided, and recent jailbreak reports don’t show the model providing unique hacking capabilities. The post Cybersecurity experts don’t think Anthropic’s Fable 5 presents a unique threat appeared first on CyberScoop.
The US government has ordered Anthropic to block all foreign nationals from accessing Fable 5 and Mythos 5, forcing the company to suspend both models worldwide. Anthropic is complying but disputes the basis, calling the cited jailbreak narrow and the capability widely available elsewhere. [...]
Cisco: One Prompt May Not Break Most AI Models, But a Conversation WillCisco tested eight major open-weight artificial intelligence models and found multi-turn jailbreak attacks succeeded nearly 93% of the time, exposing a blind spot in how enterprises assess and deploy large language models safety.
No worries if the US doesn't want to be friends with Europe anymore Lockheed Martin's F-35 fighter aircraft can be jailbroken "just like an iPhone," the Netherlands' defense secretary has claimed.…
If an attacker splits a malicious prompt into discrete chunks, some large language models (LLMs) will get lost in the details and miss the true intent.
Cybercriminals are increasingly using AI to lower the barrier to entry for fraud and hacking, shifting from skill-based to AI-assisted attacks known as "vibe hacking." Flare examines how underground forums promote AI tools, jailbreak techniques, and so-called "Hacking-GPT" services that promise ease rather than technical mastery. [...]
When prompts were presented in poetic rather than prose form, attack success rates increased from 8% to 43%, on average — a fivefold increase.
Dorm management refuses to cover costs after payment system borked More than a thousand university students in the Netherlands must continue to travel to wash their clothes after their building management company failed to bring its borked smart laundry machines back online.…
Experts Say AI Model Makers Are Prioritizing Profit Over SecurityHackers don't need the deep pockets of a nation-state to break GPT-5, OpenAI's new flagship model. Analysis from artificial intelligence security researchers finds a few well-placed hyphens are enough to convince the large language model into breaking safeguards against adversarial prompts.
A new technique has bypassed GPT-5’s safety systems via narrative-driven steering to elicit harmful output
Researchers paired the jailbreaking technique with storytelling in an attack flow that used no inappropriate language to guide the LLM into producing directions for making a Molotov cocktail.
Cybersecurity researchers have uncovered a jailbreak technique to bypass ethical guardrails erected by OpenAI in its latest large language model (LLM) GPT-5 and produce illicit instructions
Researcher Details Stealthy Multi-Turn Prompt Exploit Bypassing AI SafetyWell-timed nudges are enough to derail a large language model and use it for nefarious purposes, researchers have found. Dubbed "Echo Chamber," the exploit uses a chain of subtle prompts to bypass existing safety guardrails by manipulating the model's emotional tone and contextual assumptions.
Cybersecurity researchers are calling attention to a new jailbreaking method called Echo Chamber that could be leveraged to trick popular large language models (LLMs) into generating undesirable responses, irrespective of the safeguards put in place
What is PLeak, and what are the risks associated with it? We explored this algorithmic technique and how it can be used to jailbreak LLMs, which could be leveraged by threat actors to manipulate systems and steal sensitive data.
Various generative artificial intelligence (GenAI) services have been found vulnerable to two types of jailbreak attacks that make it possible to produce illicit or dangerous content
Lovable, a generative artificial intelligence (AI) powered platform that allows for creating full-stack web applications using text-based prompts, has been found to be the most susceptible to jailbreak attacks, allowing novice and aspiring cybercrooks to set up lookalike credential harvesting pages
