🔓 Cisco Talos has linked a large-scale credential harvesting campaign to a threat cluster tracked as UAT-10608 that exploited CVE-2025-55182 in React Server Components and the Next.js App Router to breach at least 766 hosts. The intruders deployed a multi-stage dropper that collected environment variables, SSH keys, cloud metadata credentials, API keys, and other secrets before aggregating them in a password-protected web GUI called NEXUS Listener. Researchers accessed an exposed instance and observed a broad array of stolen items, including Stripe keys, GitHub tokens, AI platform keys, webhook secrets, and database connection strings. Organizations are urged to patch vulnerable Next.js deployments, enforce least privilege, enable IMDSv2, rotate credentials, and implement secret scanning.

🔒 APIs are increasingly the enterprise perimeter, and recent breaches show traditional protections often miss API-layer abuse. Security teams report attacks that exploit business logic or use stolen credentials, which EDR and WAF tools can treat as legitimate traffic. CISOs are adopting API governance, centralized inventories, identity-aware access controls, and API gateways integrated into CI/CD to enforce least-privilege and reduce misconfiguration risk. As agentic AI and automated agents proliferate, stronger token handling, credential rotation, and real-time behavioral monitoring are becoming essential.

🔓 Lloyds Banking Group has disclosed a software glitch that briefly allowed some mobile app users to see other customers' transactions. The bank told the UK Parliament’s Treasury Committee the problem followed an overnight IT change and a defect in the design of the code used to update the API behind the app. Of 21.6 million app users, 447,936 may have been shown another user's transactions and 114,182 may have viewed transaction details during the incident. Lloyds said no full account access or customer losses were identified and that it notified regulators, including the ICO.

🔒 Ajax Amsterdam disclosed that a hacker exploited vulnerabilities in its IT systems, allowing access to some fan data and control over ticket transfers. The club said only email addresses for a few hundred people were viewed and that fewer than 20 stadium-banned individuals had names, emails and dates of birth exposed. RTL journalists, tipped by the attacker, independently verified the flaws and demonstrated the ability to transfer season tickets, modify stadium bans and access broad fan data via APIs and shared keys. Ajax has engaged external experts, patched the vulnerabilities, notified authorities and advised fans to remain vigilant for impersonation attempts.

🔍Salesforce has warned that a threat actor is using a customized version of the open-source tool AuraInspector to mass-scan publicly accessible Experience Cloud sites and exploit overly permissive guest user configurations. The modified tool can both identify vulnerable API endpoints and extract data from misconfigured environments without authentication. Salesforce says the activity targets customer configuration weaknesses rather than a platform flaw and urges customers to review guest user settings and follow recommended configuration guidance.

🔒 Salesforce warns customers that attackers are targeting misconfigured Experience Cloud sites by abusing the /s/sfsites/aura API, allowing guest users to access more data than intended. Threat actors have used a modified AuraInspector scanner and bespoke exfiltration tools; the extortion group ShinyHunters claims responsibility and reports hundreds of compromises. Salesforce stresses this stems from customer guest‑user settings, not a platform vulnerability, and provides immediate mitigation guidance.

🔒 SafeLine is presented as a self-hosted web application firewall that inspects every HTTP request and emphasizes behavioral and semantic analysis rather than simple signature matching. It combines a Semantic Analysis Engine, anti-bot challenges, rate limiting and identity controls to reduce fake sign-ups, credential stuffing, scraping and abusive automation. Deployable as a reverse proxy, it gives SaaS teams control over logs, latency and compliance while providing a dashboard for tuning and visibility.

🔓 Google Cloud API keys that were once treated as non-sensitive can now authenticate to the Gemini generative AI assistant, creating a new attack path where keys embedded in client-side JavaScript expose private assistant data. TruffleSecurity discovered nearly 2,800 live, publicly accessible keys across sectors — including financial firms and a Google product — by scanning the November 2025 Common Crawl. Attackers who copy exposed keys can call Gemini endpoints to retrieve data or generate costly API usage; developers should audit projects for the Generative Language API, rotate exposed keys immediately, and use detection tools to prevent abuse.

🔒 Marquis Software Solutions has filed suit against SonicWall, alleging gross negligence and misrepresentation after a ransomware attack on August 14, 2025 that followed a compromise of a SonicWall firewall. Investigators say the attacker accessed configuration backups stored in SonicWall’s MySonicWall cloud—an exposure Marquis attributes to an API code change in February 2025—and used configuration data and AES-256-encrypted credentials to bypass MFA. The stolen files included extensive personal and financial information; Marquis says the incident disrupted operations for 74 U.S. banks and forced the firm to defend more than 36 consumer class actions while seeking monetary damages, indemnification and equitable relief.

🔐 Modern LLM deployments expand rapidly, and each new endpoint increases the attack surface, often with implicit trust and excessive permissions. Internal APIs, long-lived tokens and misconfigurations frequently expose endpoints that act as pivot points to databases, tools and cloud services. Organizations should apply least-privilege, just-in-time access and automated secrets rotation to limit damage. Solutions like Keeper help implement endpoint privilege management.

🔒 Google Threat Intelligence Group, working with industry partners, disrupted the IPIDEA residential proxy network by taking down domains, infected-device management systems, and proxy-traffic routing infrastructure. The operation targeted SDKs embedded in at least 600 trojanized Android apps and over 3,000 malicious Windows binaries, which collectively enrolled about 6.7 million devices worldwide. GTIG reported that more than 550 distinct threat groups abused IPIDEA for account takeovers, credential theft, botnet control, and DDoS support; users should avoid untrusted VPNs and apps that pay for bandwidth.

🔒 Researchers at Pillar Security warn of large-scale campaigns that probe and exploit exposed LLM and MCP endpoints to steal compute, exfiltrate context data, and resell API access. In recent weeks, honeypots captured roughly 35,000 attack sessions linked to Operation Bizarre Bazaar and a parallel MCP reconnaissance effort that leverage Shodan/Censys scanners, automated validators, and a criminal marketplace. Threat actors target unprotected Ollama, vLLM and OpenAI-compatible endpoints and are marketing discounted access via a site called The Unified LLM API Gateway. Organizations must require authentication, audit MCP exposure, apply rate limits, block known malicious ranges, and treat AI endpoints with the same rigor as APIs and databases immediately.

🔒 Researchers at Pillar Security recorded over 35,000 attack sessions in a 40-day window revealing a large-scale operation they call Bizarre Bazaar, an instance of LLMjacking that monetizes exposed LLM endpoints. The campaign targets misconfigured self-hosted models, unauthenticated APIs (notably Ollama on port 11434 and OpenAI-compatible services on port 8000), and publicly accessible MCP servers. Compromised endpoints are used for cryptocurrency mining, reselling API access through a marketplace dubbed silver[.]inc, data exfiltration, and lateral movement into internal systems.

🔍 Threat actors have been probing misconfigured proxy servers to access paid large language model (LLM) endpoints, generating over 80,000 sessions since late December, according to GreyNoise. Attackers used low-noise queries to fingerprint models without triggering alerts and targeted vendors such as OpenAI, Anthropic, Google, Meta, Mistral and others. While GreyNoise reports no observed exploitation or data theft, the scale of enumeration indicates reconnaissance with possible malicious intent. Recommended mitigations include restricting Ollama model pulls to trusted registries, applying egress filtering, blocking known OAST callback domains at DNS, rate-limiting suspicious ASNs, and monitoring JA4 fingerprints.

🔒 Google has filed a lawsuit against the scraping company SerpApi for circumventing security measures and taking copyrighted content that appears in Search results. The complaint alleges SerpApi cloaks its bots, rotates identities, and bombards websites to harvest licensed images and real‑time Search data, which it then resells for a fee. Google says it resorted to legal action after technical protections were repeatedly bypassed in order to protect publishers and rightsholders.

🔒 700Credit, a Michigan fintech serving more than 20,000 car dealerships, disclosed a breach affecting 5.8 million customers. The company said a misconfigured API allowed unauthorized copying of records between May and October, exposing names, addresses and Social Security numbers. Discovered on October 25, 700Credit engaged cybersecurity experts who found activity limited to the 700Dealer.com application layer and reported no evidence of identity theft. Affected individuals are being offered 12 months of TransUnion identity protection and credit monitoring at no cost.

🔒 700Credit is notifying more than 5.8 million individuals after a threat actor exploited an exposed API to obtain customer records tied to dealership clients. The company detected suspicious activity on October 25 and, with third-party forensic assistance, confirmed unauthorized copying of web application records. Exposed data includes full names, addresses, dates of birth, and Social Security numbers. 700Credit is offering 12 months of complimentary identity protection through TransUnion and has filed breach notifications with the FTC and affected dealer clients.

🔍 Elastic Security Labs has detailed a Windows backdoor named NANOREMOTE that leverages the Google Drive API to stage payloads and exfiltrate data, making detection more difficult. The C++ implant implements a robust task manager for queued uploads and downloads with pause, resume and cancel capabilities and exposes 22 command handlers for reconnaissance, execution and file transfer. Researchers also observed a WMLOADER dropper and an uploaded artifact linking NANOREMOTE to the FINALDRAFT family, indicating likely code reuse.

🛡️ A malicious Chrome extension named Crypto Copilot was found injecting covert Solana transfers into Raydium swap transactions, diverting funds to an attacker-controlled wallet. Published by "sjclark76" on May 7, 2024, the add-on remains available on the Chrome Web Store with 12 installs. The extension appends a hidden SystemProgram.transfer to each swap before signature, charging a minimum of 0.0013 SOL (and applying a 2.6 SOL/0.05% rule) while obfuscating its code to evade detection. It also contacts backend domains to register wallets and report activity, giving a false veneer of legitimacy.

🔒 New research from watchTowr Labs found over 80,000 files saved to online code-formatting tools, exposing thousands of passwords, API keys, repository tokens and other sensitive credentials across government, telecoms, finance, healthcare and critical infrastructure. The datasets comprise five years of JSONFormatter content and one year of CodeBeautify content (about 5GB), and both services used predictable, shareable URLs and a Recent Links page that made mass crawling trivial. Researchers uploaded decoy AWS keys that were abused within 48 hours, and both sites have temporarily disabled save functionality while implementing enhanced content-prevention measures.
