Attackers Inject Malware into Popular npm Packages

🚨 Attackers phished and hijacked a package maintainer's account via a fake support domain, then updated index.js files in multiple npm packages to inject a browser-based interceptor. The malicious code targets web clients, monitoring Ethereum, Bitcoin, Solana, Tron, Litecoin and Bitcoin Cash transactions and replacing wallet destinations to redirect funds. Affected packages collectively account for over 2.6 billion weekly downloads, making this a substantial supply-chain compromise. Investigation and remediation are ongoing.

Salesloft March GitHub Breach Led to Salesforce Data Theft

🔒 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.

GitHub Account Compromise Led to Salesloft Drift Breach

🔒 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.

Written in Easy Programming Language, the malware deploys a multi-stage chain, uses mutual TLS for C2 communication, and can disable Windows Update and antivirus processes. The campaign, aimed largely at Japanese users, begins with phishing emails that lead to a malicious Word download and installs services running at SYSTEM-level, while deploying remote access tools such as AnyDesk and TightVNC.

German Cyberattack Forces Wehrle-Werk AG into Insolvency

🔒 Wehrle-Werk AG has filed for insolvency after 165 years of operation, citing a damaging cyberattack in May 2024 that severely disrupted production, communications and business processes. A provisional insolvency administrator has been appointed to secure operations, conduct talks with customers and suppliers, and arrange pre-financing of insolvency wages to ensure employee pay for the coming months. The Baden-Württemberg firm, which employs around 250 staff and specializes in environmental technology—thermal waste disposal, sewage sludge combustion for phosphorus recovery and wastewater treatment—reported that its subsidiaries in Switzerland, Spain, the UK, Russia and Malaysia are not affected.

GhostAction Campaign Steals 3,325 Secrets via GitHub Actions

🔍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.

Qualys, Tenable Confirm Access in Salesloft Drift Attack

🔐 Tenable and Qualys reported limited unauthorized access to parts of their Salesforce records after attackers stole OAuth tokens from the Salesloft Drift integration.

Both firms disabled the Salesloft Drift app, revoked or rotated credentials, and said they are working with Salesforce and investigators to contain the impact.

Salesloft–Drift Supply Chain Breach and Weekly Recap

🔒 Salesloft has moved to take Drift offline after a supply‑chain compromise that resulted in the mass theft of OAuth tokens and unauthorized access to Salesforce data. Multiple large vendors — including Cloudflare, Google Workspace, PagerDuty, Palo Alto Networks, and Tenable — confirmed impact, and activity is attributed to clusters tracked as UNC6395 and GRUB1. The incident underscores how fragile integrations can be and the importance of token hygiene, rapid revocation, and enhanced monitoring to contain downstream exposure.

GhostAction Supply-Chain Attack Steals 3,325 Secrets

🔒 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.

German Companies Affected by 2024–2025 Cyberattacks

🔒 In 2024 and into 2025, a wide range of German companies — from small and mid-sized enterprises to publicly listed groups and critical-service providers — were struck by ransomware and other intrusions, causing operational disruptions, lost revenue, supply-chain effects and reputational harm. Notable victims include Volkswagen Group, Adidas, Samsung Germany and several defence and manufacturing firms, while IT service providers and regional utilities were also targeted. At least one company (Fasana GmbH) reported insolvency after an attack. The editorial team updates this list regularly, but it is not exhaustive.

iCloud Calendar abused to send phishing via Apple Servers

📅 iCloud Calendar invites are being abused to send callback phishing emails that appear to originate from Apple's servers and pass SPF, DKIM, and DMARC checks. Attackers embed phishing content in the event Notes and invite a Microsoft 365 forwarding address so the message is relayed to targets while Apple remains the visible sender. Treat unexpected calendar invites with unusual messages or requests cautiously; calling listed numbers or granting remote access can lead to fraud, malware, or data theft.

VirusTotal Uncovers SVG-based Judicial Portal Phishing

🔍 VirusTotal's AI Code Insight detected a sophisticated phishing campaign that hid malicious JavaScript inside SVG images to impersonate Colombia's judicial system. The SVGs rendered fake portal pages with a bogus download progress bar and displayed a password for a protected ZIP archive that contained malware artifacts. The archive included a renamed Comodo Dragon executable, a malicious DLL, and two encrypted files; when the executable runs the DLL is sideloaded to install further malware. After adding SVG support, VirusTotal found 523 related SVGs that had evaded traditional antivirus detection.

Noisy Bear Targets Kazakhstan Energy Firm with Phishing

🚨 Operation BarrelFire, attributed to a group Seqrite Labs calls Noisy Bear, targeted Kazakhstan's national oil company KazMunaiGas in May 2025 using tailored phishing. Attackers sent ZIP attachments containing an .LNK downloader, a decoy document, and a README in Russian and Kazakh instructing use of a fake KazMunayGaz_Viewer. The chain deployed a malicious batch, a PowerShell loader named DOWNSHELL, and a 64-bit DLL implant that executes shellcode to open a reverse shell. Infrastructure was linked to Russia-based bulletproof host Aeza Group, which has been sanctioned.

AI-powered Nx malware exposes 2,180 GitHub accounts

🔒 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.

Malicious npm Packages Impersonate Flashbots, Steal Keys

🔑 Researchers found four malicious npm packages impersonating Flashbots and common cryptographic utilities to harvest Ethereum wallet credentials. Uploaded by user "flashbotts" between September 2023 and August 19, 2025, the libraries exfiltrate private keys and mnemonic seed phrases to a Telegram bot and transmit environment data via Mailtrap SMTP. One package also redirects unsigned transactions to an attacker-controlled wallet.
