OpenAI discovered that ChatGPT and other tools powered by its GPT-5 model were randomly mentioning goblins, gremlins, and other creatures in their responses, with goblin mentions increasing 175% after the GPT-5.1 launch in November. The problem stemmed from a "nerdy personality" developed during training that was rewarding mentions of these creatures in metaphors, and OpenAI found this personality was responsible for 66.7% of all goblin mentions. The issue illustrates how AI training systems can accidentally reinforce quirks and errors when they reward certain language patterns.
Fix: OpenAI said it took steps to mitigate the issue by instructing its coding agent Codex to avoid referring to goblins, gremlins, raccoons, trolls, ogres, pigeons, and other creatures "unless it is absolutely and unambiguously relevant to the user's query." The company also retired the "nerdy personality" system that had been incentivizing these mentions.
BBC TechnologyA critical vulnerability in Gemini CLI, an open source AI agent for terminal access to Google's Gemini, allowed attackers to execute arbitrary code on the host system by planting malicious configuration files in a workspace folder. The flaw was particularly dangerous in CI/CD pipelines (automated systems that build, test, and deploy software) because attackers could steal credentials and perform supply chain attacks (compromising software before it reaches users) by exploiting the trusted access that these pipelines have.
A maximum-severity vulnerability in Google Gemini CLI allowed remote code execution (RCE, where attackers can run commands on a system they don't own) when the tool processed untrusted inputs in automated environments like CI/CD pipelines (automated workflows that test and deploy code). The flaw occurred because the CLI automatically trusted workspace configurations without verification, letting attackers inject malicious code that would execute before security protections kicked in.
Despite heavy promotion by tech companies, young people (Gen Z) are increasingly using AI chatbots like ChatGPT while simultaneously expressing strong negative feelings toward AI technology. Polling data shows widespread cultural backlash against AI among Gen Z students and workers, even as they continue to adopt these tools.
A supply chain attack called "mini Shai-Hulud" compromised npm packages (code libraries hosted on npm, a JavaScript package repository) used in SAP development, injecting malware that stole developer credentials and cloud secrets during installation. The attackers exploited configuration gaps in npm's OIDC trusted publishing (a system that verifies package publishers) and used stolen credentials to add malicious GitHub Actions workflows (automated tasks in code repositories) and persist through developer tool configuration files, treating developer workstations as entry points to compromise the entire software supply chain.
The Office of the Director of National Intelligence's 2026 Annual Threat Assessment has shifted away from long-term forecasting about foreign adversaries to focus on immediate domestic security issues, removing detailed sections on threats from countries like China and Russia. This change signals that the US intelligence community is contracting its strategic analysis and implicitly telling private companies and security leaders that they must now assess cyber threats, infrastructure vulnerabilities, and adversary tactics largely on their own rather than relying on government intelligence guidance.
Google patched a critical flaw (CVSS score of 10.0, the highest severity) in Gemini CLI that allowed attackers to execute arbitrary commands by tricking the tool into loading malicious configuration files in headless mode (non-interactive environments used in CI/CD pipelines, which automate software testing and deployment). The vulnerability affected versions before 0.39.1 and 0.40.0-preview.3 of the npm package and version 0.1.22 of the GitHub Actions workflow. Separately, a high-severity flaw in Cursor (a code-writing AI tool) before version 2.5 could also enable code execution through prompt injection (tricking an AI by hiding instructions in its input).
This article discusses Elon Musk's testimony in a legal case, noting that his cross-examination performance was problematic, with him frequently refusing to give direct yes-or-no answers and appearing to contradict his earlier testimony. The piece suggests his defensive behavior and communication style during questioning may have negatively influenced the jury's perception of his credibility.
This is a brief announcement about llm 0.32a1, which appears to be a pre-release version (indicated by the 'a1' suffix) of an LLM-related tool or library. The post was written by Simon Willison on April 29, 2026, and includes a sponsorship offer for a monthly email digest of important LLM developments.
Elon Musk is suing OpenAI and its co-founders, claiming they broke a charitable trust by shifting the organization from a non-profit (a company structured to serve the public good rather than generate profit) to a for-profit model. OpenAI argues Musk is motivated by jealousy and competitive concerns, noting that he himself launched xAI, a competing for-profit AI startup, after leaving OpenAI in 2018.
Anthropic, an AI startup founded by former OpenAI employees, is in talks to raise funding at a $900 billion valuation, surpassing OpenAI's recent $852 billion valuation. The company has been racing to compete with OpenAI since ChatGPT's launch in 2022, and is now seeking capital primarily to purchase compute (computing power needed to train and run AI models) for its latest Claude AI model called Mythos, which has advanced cybersecurity capabilities.
The Claude SDK for TypeScript had a security flaw where a tool called `BetaLocalFilesystemMemoryTool` created files and folders with overly permissive access settings (using Node.js defaults like `0o666` for files and `0o777` for directories, which control who can read or modify them). This meant that on shared computers or in containerized environments (like Docker), other users could read sensitive agent data or modify it to change how the AI behaves.
AI-powered GitHub Actions from companies like OpenAI, Anthropic, and Google have a critical security flaw where prompt injection (tricking an AI by hiding instructions in its input) attacks can be triggered by external attackers, even when configuration settings are meant to restrict access. The vulnerability stems from these actions not properly distinguishing between trusted internal apps and untrusted external apps, allowing anyone to potentially manipulate the AI's behavior through pull requests, issues, or other user-controlled inputs.
Person re-identification (ReID) systems, which match images of the same person across different camera views, are vulnerable to a new attack called DSCA (diffusion-based semantic camouflage attack). Instead of changing individual pixels, DSCA uses a generative model to subtly alter high-level features like clothing color and texture to trick the system into matching an attacker with a target identity without needing access to the victim system. The researchers demonstrated this attack succeeds over 95% of the time and evades existing defenses, revealing important security gaps that developers should address.
Researchers created SemBugger, a polymorphic backdoor attack (a type of hidden malicious code that can change its behavior) against semantic communication (SC, a system where AI learns shared knowledge to compress and transmit information efficiently). The attack uses variable-intensity triggers to poison training data and manipulate the system into producing different malicious outputs while appearing normal, but the researchers also developed a defense mechanism using controlled noise that can resist these attacks.
Fix: The source proposes a provable robustness defense that resists SemBugger attacks through a controlled noise mechanism, which operates by strategically adding noise to semantic communication inputs, with theoretical lower bounds on defense effectiveness provided. Experiments show this designed defense effectively neutralizes SemBugger attacks.
IEEE Xplore (Security & AI Journals)Fix: The vulnerability was patched by Google in both Gemini CLI and the 'run-gemini-cli' GitHub Action.
SecurityWeekFix: The issue was fixed in @google/gemini-cli versions 0.39.1 and 0.40.0-preview.3, and in run-gemini-cli version 0.1.22. The patches removed implicit workspace trust in headless (non-interactive) environments and now require explicit trust decisions before loading workspace configurations. Additionally, the fix enforces stricter tool allowlisting (a list of permitted commands) to prevent command execution outside intended restrictions. Workflows that pin a specific gemini-cli version are advised to upgrade to a patched release and review their existing Gemini CLI configurations.
CSO OnlineOpenAI is launching GPT-5.5-Cyber, a specialized AI model designed to help organizations defend against cyberattacks, but it will only be available to a limited group of vetted "cyber defenders" rather than the general public. The company plans to roll out access within days and will work with other organizations and government agencies to establish a trusted access system for the model.
As AI agents (AI systems that can connect to databases, applications, and external systems to execute multi-step tasks) become more widely deployed, organizations are giving them excessive permissions, allowing them to access systems and take actions beyond what they actually need. The real security risk has shifted from AI producing wrong answers to AI taking unauthorized actions at scale, such as exposing data or making integrity-impacting changes, because most organizations lack formal risk management frameworks and visibility into how agent permissions are controlled across connected systems.
Fix: Google's fix requires explicit folder trust before configuration files can be accessed. Users should review workflows and choose one of two approaches: (1) if the workflow runs on trusted inputs, set the environment variable GEMINI_TRUST_WORKSPACE: 'true' in the workflow, or (2) if it runs on untrusted inputs, review Google's guidance and set the environment variable while hardening the workflow against malicious content. Additionally, in version 0.39.1, the Gemini CLI policy engine now evaluates tool allowlisting under --yolo mode (auto-approve mode) to prevent untrusted inputs from triggering code execution via prompt injection. Users should update to @google/gemini-cli version 0.39.1 or later, @google/gemini-cli version 0.40.0-preview.3 or later, and google-github-actions/run-gemini-cli version 0.1.22 or later.
