Nono: Open-source sandbox for AI agents

Help Net Security

July 27, 2026 at 5:30 AM

Overview

A new open-source AI sandbox called Nono has raised concerns about security vulnerabilities. When an AI coding agent operates within this environment, it can access sensitive information such as cloud keys stored in plaintext. This means that if the agent is improperly prompted or given incorrect commands, it may inadvertently access and misuse the company's credentials or files that the user has permission to read. This situation poses a significant risk, as any misstep could lead to unauthorized access to critical company data. Organizations using this sandbox need to be aware of these potential pitfalls to protect their sensitive information.

Key Takeaways

Affected Systems: Nono open-source AI sandbox
Action Required: Ensure sensitive keys and credentials are not stored in plaintext; implement strict access controls and user permissions within the AI environment.
Timeline: Newly disclosed

Original Article Summary

An AI coding agent opens a terminal, reads a config file, and finds a live cloud key sitting in plaintext. It runs with the permissions of the person who launched it. Every file that person can read, the agent reads. Every credential in the environment, the agent can use. That reach is where the damage starts. A prompt injection, a mistyped command, or a hallucinated path points that access at the company’s own credentials and … More → The post Nono: Open-source sandbox for AI agents appeared first on Help Net Security.

AI Speeds Up Malware Development, Not Its Success Rate: Analysis

SecurityWeek

A recent analysis by Palo Alto Networks' Unit 42 examined 405 malware samples that are linked to artificial intelligence. The findings revealed that while AI can accelerate the development of malware, it does not necessarily improve its success rate. Out of the analyzed samples, only 12 managed to reach production endpoints, which indicates that most AI-generated malware struggles to effectively infiltrate systems. This study is significant as it suggests that while cybercriminals may adopt AI to create malware more quickly, the effectiveness of these tools remains limited. Companies and security teams should continue to focus on traditional defenses as the majority of AI-linked malware is not successfully deployed.

Snowflake ends service-account passwords. Now comes the hard part

BleepingComputer

Snowflake has decided to discontinue password authentication for its legacy service accounts, which means organizations will need to switch to passwordless authentication methods. This change aims to enhance security by reducing reliance on passwords, but it poses significant challenges for companies. They must identify what each service account is used for, who manages them, and the level of access each account requires. This process is crucial to ensure that the migration to passwordless systems does not disrupt operations or leave any security gaps. As organizations navigate this transition, they will need to carefully assess their service account configurations and access controls.

Election official says Tina Peters would be consultant, won’t have access to election systems

CyberScoop

Shasta County's registrar, Clint Curtis, has announced plans to enlist Tina Peters as a consultant for the county's 2026 elections. Despite Peters' past conviction related to election security breaches in Colorado, Curtis expressed confidence in her ability to assist with managing the election process. He emphasized that Peters would not have access to any election systems, aiming to alleviate concerns about potential security risks. This decision has sparked debate, particularly given Peters' controversial history in the election integrity realm. The implications of bringing someone with her background into a role, even without system access, could affect public trust in the electoral process.

CISA Red Team Compromised Two Critical Infrastructure Orgs, One Detected Nothing

The Hacker News

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) recently completed red team assessments on two critical infrastructure organizations, both of which were compromised at the domain level. Despite using similar tactics, only one organization detected the intrusion. This stark difference in defensive outcomes raises concerns about the readiness of critical infrastructure sectors to withstand cyberattacks. The findings emphasize the need for improved security measures and threat detection capabilities within these organizations to better protect against potential breaches that could disrupt essential services. CISA's assessment serves as a crucial reminder of the vulnerabilities that exist within critical infrastructure and the ongoing need for vigilance in cybersecurity practices.
