🔒 Salesloft says attackers first breached its GitHub account in March, enabling the theft of Drift OAuth tokens later abused to access customer systems. The stolen tokens were used in widespread Salesforce data-theft operations disclosed in August, affecting multiple enterprise customers. Salesloft engaged Mandiant, rotated credentials, isolated Drift infrastructure, and restored integrations after validating containment.

🔒 Salesloft says the breach tied to its Drift application began after a threat actor compromised its GitHub account. Google-owned Mandiant traced the actor, tracked as UNC6395, accessing the account from March through June 2025 and downloading repository content, adding a guest user and establishing workflows. Attackers then accessed Drift's AWS environment and obtained OAuth tokens used to reach customer data via integrations, prompting Salesloft to isolate Drift infrastructure and take the application offline on September 5, 2025. Salesloft recommends revoking API keys for third-party apps integrated with Drift, and Salesforce has restored most Salesloft integrations while keeping Drift disabled pending further remediation.

🔍GitGuardian disclosed a GitHub Actions supply chain campaign named GhostAction that exfiltrated 3,325 secrets from 327 users across 817 repositories before being contained on September 5. Attackers injected malicious workflow files to harvest CI/CD tokens (including PYPI_API_TOKEN) and sent them via HTTP POST to an actor-controlled endpoint. GitGuardian coordinated with maintainers and registries to revert commits, set impacted packages to read-only, and notify vendors.

🔒 GitGuardian uncovered a widespread supply-chain campaign it named GhostAction after detecting suspicious activity in a FastUUID GitHub repository. A compromised maintainer pushed a malicious GitHub Actions workflow that harvested secrets, initially capturing a PyPI token, and further investigation revealed hundreds of similar commits across multiple repositories. In total 3,325 secrets were exfiltrated from 817 repositories belonging to 327 users, with DockerHub credentials, GitHub tokens and npm tokens among the most common. GitGuardian notified platform security teams and many affected projects have begun reverting malicious changes while investigations continue.

🔒 A backdoored NPM package published from the Nx repository delivered a post-install credential stealer named telemetry.js, which targeted Linux and macOS systems for GitHub and npm tokens, SSH keys, .env files and crypto wallets. The malware exfiltrated harvested secrets to public repositories named s1ngularity-repository. Attackers unusually used AI CLI tools (Claude, Q, Gemini) to run tuned LLM prompts for better credential harvesting. Nx and GitHub removed the packages, revoked tokens, and implemented 2FA, tokenless publishing and manual PR approvals.

⚠️ ReversingLabs researchers uncovered a supply chain campaign that used Ethereum smart contracts to conceal URLs for malware delivered via rogue GitHub repositories and npm packages. The packages colortoolsv2 and mimelib2 were intentionally minimal and designed to be pulled as dependencies from fraudulent repositories posing as cryptocurrency trading bots. Attackers inflated commit histories with sockpuppet accounts and automated pushes to appear legitimate, then used on-chain storage to hide secondary payload locations and evade URL-scanning defenses.

🔒 Cybersecurity researchers discovered two malicious npm packages that use Ethereum smart contracts to hide commands and deliver downloader malware to compromised systems. The packages — colortoolsv2 (7 downloads) and mimelib2 (1 download) — were uploaded in July 2025 and removed from the registry. The campaign leveraged a network of GitHub repositories posing as crypto trading tools and is linked to a distribution-as-service operation called Stargazers Ghost Network. Developers are urged to scrutinize packages and maintainers beyond surface metrics before adopting libraries.

🔍 Researchers at ReversingLabs found a loophole in the Visual Studio Code Marketplace that permits threat actors to republish removed extensions under the same visible names. The new malicious package, ahbanC.shiba, mirrors earlier flagged extensions and acts as a downloader for a PowerShell payload that encrypts files in a folder named "testShiba" and demands a Shiba Inu token ransom. Investigation revealed that extension uniqueness is enforced by the combination of publisher and name, not the visible name alone, enabling attackers to reuse names once an extension is removed. Organizations should audit extension IDs, enforce whitelists, and run automated supply-chain scanning to reduce exposure.

🔎 Microsoft recounts its transition from an early Linux contributor in 2009 to one of the largest open-source supporters in cloud and AI today. The post highlights Azure as a top contributor to the CNCF, the 2015 launch of VS Code, the 2018 GitHub acquisition, and the role of AKS and managed PostgreSQL in enterprise deployments. It also describes COSMIC, explains how OpenAI’s ChatGPT runs at global scale on Azure infrastructure, and lists projects Azure teams are building in the open.

🔒 UpGuard discovered a public GitHub repository on 13 January 2020 containing an Amazon Web Services engineer’s personal identity documents and numerous system credentials. The repository included AWS key pairs (including a file named rootkey.csv), API tokens, private keys, passwords, logs, and customer-related templates. UpGuard reported the exposure to AWS Security within hours and the repository was secured the same day. The incident highlights how rapid leak detection can prevent accidental disclosures from escalating.

🔒 UpGuard's Cyber Risk Research team discovered and secured a public GitHub-based data exposure belonging to OneHalf, a business process outsourcing firm in the APAC region. The exposed repositories contained HR and medical databases with detailed personal records for hundreds of employees, plus banking account numbers for several corporate clients. UpGuard notified OneHalf and the repositories were taken private, likely preventing further exploitation of sensitive personal and business information.

⚠️ UpGuard identified on 13 January 2020 a public GitHub repository containing sensitive material tied to an Amazon Web Services engineer. The repo, roughly 954 MB when downloaded, included personal identity documents, bank statements, log files, AWS key pairs (including a file labeled rootkey.csv), private keys, passwords and third-party API tokens. UpGuard analysts detected the exposure within half an hour, notified AWS Security early that afternoon, and the repository was taken out of public view the same day. Rapid detection and remediation appear to have prevented escalation; there is no evidence of malicious intent or end-user data compromise.
