Stolen credentials can enable account takeover and lateral movement; phishing-resistant MFA, password managers, and rapid revocation reduce the risk.

Background for this topic.
Credentials are the data used to verify a user's identity to a system, commonly including usernames, passwords, security tokens, or biometric identifiers. They serve as gatekeepers for access to accounts, applications, and sensitive information. Attackers target credentials to impersonate users, escalate privileges, or gain unauthorized system access.
Compromise of credentials can occur through phishing, credential stuffing, or theft from insecure storage. Effective defenses include enforcing strong, unique passwords, implementing multi-factor authentication (MFA), and securely storing credentials using hashing or encryption. Monitoring for unusual login patterns and promptly revoking compromised credentials are also critical to limit attacker impact.
A supply chain attack targeting the Laravel Lang localization packages has exposed developers to a sophisticated credential-stealing malware campaign after attackers abused GitHub version tags to distribute malicious code through Composer packages. [...]
Cybersecurity researchers have flagged a fresh software supply chain attack campaign that has targeted multiple PHP packages belonging to Laravel-Lang to deliver a comprehensive credential-stealing framework
A multi-stage attack on Linux devices began with an exposed F5 BIG-IP edge appliance and pivoted to an internal Confluence server for credential theft and identity compromise. Learn how the threat actor attempted Kerberos relay and lateral movement, and how Microsoft Defender detected, blocked, and unraveled the attack. The post From edge appliance to enterprise compromise: Multi-stage Linux intrusion via F5 and Confluence appeared first on Microsoft Security Blog.
Lawmakers in both houses of Congress are demanding answers from the U.S. Cybersecurity & Infrastructure Security Agency (CISA) after KrebsOnSecurity reported this week that a CISA contractor intentionally published AWS GovCloud keys and a vast trove of other agency secrets on a public GitHub account. The inquiry comes as CISA is still struggling to contain the breach and invalidate the leaked credentials.
Leakage blamed on treacherous friends exposed unencrypted credentials, email addresses
Consider a cached access key on a single Windows machine. It got there the way most cached credentials do - a user logged in, and the key stored itself automatically. Standard AWS behavior. No one misconfigured anything or violated a policy. Yet that single key, which was easily accessible to a minor-league attacker, could have opened a path to some 98% of entities in the company's cloud
A solo Russian-speaking threat actor ran a 5-year Telegram channel and, starting September 2025, used AI to automate its content, credential theft, and a cryptocurrency fraud scheme targeting American audiences.
Threat actors brute-forced VPN credentials and bypassed multi-factor authentication (MFA) on SonicWall Gen6 SSL-VPN appliances to deploy tools used in ransomware attacks. [...]
Compromised @antv npm packages deploy the Mini Shai-Hulud payload to steal CI/CD secrets from Linux-based automation environments. The malware executes during npm install and targets credentials across GitHub, AWS, Kubernetes, Vault, npm, and 1Password platforms. The post Mini Shai Hulud: Compromised @antv npm packages enable CI/CD credential theft appeared first on Microsoft Security Blog.
Verizon DBIR finds 31% of data breaches began with software flaws last year
A researcher who found a repository that leaked on GitHub said it was one of the worst he’s witnessed. The post CISA credential leak raises alarms, and Capitol Hill demands answers appeared first on CyberScoop.
The agency's GitHub repository, publicly available since November 2025, was ironically named "Private-CISA."
Chainable Bugs Enable Credential Theft, Persistence, TakeoverFour chainable flaws in OpenClaw allowed attackers to move from an initial foothold to persistent system-level compromise by abusing the AI agent's own privileges. The bugs enabled credential theft, privilege escalation and backdoor deployment, affecting all versions released before April 23.
Cybersecurity researchers have flagged a compromised version of the Nx Console extension that was published to the Microsoft Visual Studio Code (VS Code) Marketplace
In yet another software supply chain attack, threat actors have compromised the popular GitHub Actions workflow, actions-cool/issues-helper, to run malicious code that harvests sensitive credentials and exfiltrates them to an attacker-controlled server
Storm-2949 turned stolen credentials into a cloud-wide breach, moving from identity compromise to large-scale data theft without using malware. This incident shows how threat actors can exploit trusted systems to operate undetected. The post How Storm-2949 turned a compromised identity into a cloud-wide breach appeared first on Microsoft Security Blog.
The now-patched vulnerabilities in the rapidly growing AI agent framework allow attackers to steal credentials, escalate privileges, and maintain persistence.
Until this past weekend, a contractor for the Cybersecurity & Infrastructure Security Agency (CISA) maintained a public GitHub repository that exposed credentials to several highly privileged AWS GovCloud accounts and a large number of internal CISA systems. Security experts said the public archive included files detailing how CISA builds, tests and deploys software internally, and that it represents one of the most egregious government data leaks in recent history.
Supply chain attackers are not only trying to slip malicious code into trusted software. They are trying to steal the access that makes trusted software possible. Recently, three separate campaigns hit npm, PyPI, and Docker Hub in a 48-hour window, and all three targeted secrets from developer environments and CI/CD pipelines, including API keys, cloud credentials, SSH keys, and tokens. This is
AI agents now act inside the trust boundary with real credentials, and agentic governance is what keeps them from quietly breaking things at machine speed.
