CISA reveals how it responded after sensitive AWS GovCloud credentials and internal data were exposed in a public GitHub repository

Researchers Urge Organizations to Rotate Credentials and Review Audit LogsThreat actor 888 claims it stole Accenture source code and cloud credentials, prompting researchers to warn that any exposed Azure tokens, encryption keys or DevOps secrets could enable follow-on intrusions and downstream supply-chain attacks even as Accenture says operations remain unaffected.

A Russian-speaking initial access broker (IAB) driven by financial gain is assessed to be behind a large-scale credential-harvesting operation known as FortiBleed that has targeted over 430,000 FortiGate firewalls globally

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) urged Fortinet customers to secure their devices after nearly 74,000 firewall and VPN credentials were exposed in a data leak dubbed "FortiBleed." [...]

24 Billion Records Left Open Online: Passwords, Emails, and Everything Else Exposed database with 24 Billion records revealed stolen credentials from infostealers, Telegram channels, and breach collections, risking account takeovers. Cybernews researchers found an exposed Elasticsearch cluster on June 12th containing 24 billion records and more than 8.3 terabytes of data. They triple-checked the numbers. […]

A newly discovered data leak dubbed "FortiBleed" has exposed what appears to be a collection of Fortinet and FortiGate VPN credentials for 73,932 firewall URLs at organizations worldwide. [...]

Breaches don't always start with a zero-day. An exposed admin panel can get brute-forced, or credentials reused from a previous attack. But when a vulnerability does drop — like MongoBleed earlier this year, which let attackers pull credentials and session tokens from server memory without authentication — anything internet-facing is immediately at risk

19.6 Billion files are exposed in misconfigured cloud buckets, including 685K credential files and nearly 1M database dumps. There’s a comfortable myth most people carry around: that the data they hand to companies is locked somewhere safe. Researchers at Mysterium VPN just ran the numbers, and the numbers disagree. Across 535,480 publicly listable cloud storage […]

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. [...]

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.

Leakage blamed on treacherous friends exposed unencrypted credentials, email addresses

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.

A new malware framework called PCPJack is stealing credentials from exposed cloud infrastructure while actively removing TeamPCP's access to the systems. [...]

Cybersecurity researchers have disclosed details of a new credential theft framework dubbed PCPJack that targets exposed cloud infrastructure and ousts any artifacts linked to TeamPCP from the environments

In February 2026, researchers uncovered a shift that completely changed the game: threat actors are now using custom AI setups to automate attacks directly into the kill chain

A lesson in how not to respond to vulnerability reports UPDATED Vibe-coding platform Lovable is pooh-poohing a researcher’s finding that anyone could open a free account on the service and read other users' sensitive info, including credentials, chat history, and source code. However, the company’s story keeps changing: First it attributed the publicly exposed info to "intentional behavior" and "unclear documentation," then threw bug-bounty service HackerOne under the bus.…

Six-hour breach turned trusted links into a coin toss between legit tools and credential stealers Visitors to the CPUID website were briefly exposed to malware this week after attackers hijacked part of its backend, turning trusted download links into a delivery mechanism for something far less welcome.…

An emerging threat cluster tracked as UAT-10608 is exploiting vulnerable Web-exposed Next.js apps and using an automated tool to exfiltrate credentials, secrets, and other system data.

AI Dependency Attack Reportedly Exposes Data and Source CodeA LiteLLM supply-chain compromise enabled attackers to harvest credentials and access internal environments at scale at Mercor. The firm was the first to confirm a LiteLLM breach, and researchers are warning about growing AI system exposure and limited visibility.

Anthropic on Tuesday confirmed that internal code for its popular artificial intelligence (AI) coding assistant, Claude Code, had been inadvertently released due to a human error
