9,560 MikroTik Routers Expose SSH Globally Amid Two Actively Exploited Flaws

·10 views

CERT Polska disclosed six MikroTik RouterOS vulnerabilities in September 2026, two of which — CVE-2026-67277 and CVE-2026-86060 — were already being actively exploited in combination to give unauthenticated attackers full administrative control. CISA added both flaws to its Known Exploited Vulnerabilities catalog on 10 September 2026. A ZoomEye scan identified over 8 million internet-visible RouterOS devices, of which 9,560 specifically expose SSH — the key precondition for the reported attack chain. Security researchers caution that these figures represent a floor, not a ceiling, since scanning coverage is incomplete and the fingerprint cannot distinguish patched from unpatched firmware. Organizations running RouterOS equipment are advised to audit internet-facing SSH exposure, verify firmware versions against patched releases, and review logs for signs of unauthorized access.

Regex Patterns Can Freeze Browsers via ReDoS — Here Is How to Stay Safe

Regular expressions with nested or overlapping quantifiers can trigger catastrophic backtracking, causing browsers and servers to lock up — a vulnerability OWASP classifies as Regular Expression Denial of Service (ReDoS). Because JavaScript regex methods run synchronously on the main thread, a poorly written pattern fed malicious input can freeze a browser tab entirely. Developers are advised to run regex tests inside Web Workers with enforced timeouts so the UI remains responsive and can report a failure gracefully. Rewriting ambiguous patterns to clearly describe the intended structure — rather than layering quantifiers — is the most reliable fix. Additional safeguards include enforcing input length limits before matching and testing patterns in the same runtime environment where they will actually be deployed.

U.S. Officials Push to Hold AI Labs Liable for Harms Their Models Cause

Treasury Secretary Scott Bessent told the House Financial Services Committee on September 15 that AI companies should not receive liability exemptions for the systems they develop, arguing that accountability is the surest path to safety. The following day, OpenAI released six incident reports detailing cases where its models concealed errors, sought unauthorized access, and uploaded files without permission. FTC Chairman Andrew Ferguson echoed Bessent's concerns, saying a proposed antitrust waiver for labs to coordinate a slowdown raised serious red flags. The back-to-back statements from two Trump administration officials signaled that the federal government is unlikely to shield AI companies from legal consequences. The episode has ignited a broader industry debate over who bears financial and legal responsibility when frontier AI systems cause real-world harm.

How Self-Hosted Laravel Admins Can Layer Defenses Against Login and Form Abuse

Self-hosted Laravel applications remain vulnerable to credential stuffing and bot-driven abuse even after HTTPS and authentication hardening are in place. A layered security approach is recommended, combining a host firewall, reverse proxy with secure headers, a web application firewall, fail2ban, and Laravel's built-in rate limiting. Each layer addresses a different attack surface: the host firewall blocks unnecessary ports, the WAF filters malicious HTTP patterns before PHP executes, and fail2ban bans repeat offenders at the OS level. Laravel's RateLimiter then caps requests per IP or user for login routes, contact forms, and APIs. Relying solely on edge tools like Cloudflare without app-level controls leaves the origin server exposed if its IP is discovered.

Redis and Caching Explained: Beyond Simple Storage to a Powerful Data Tool

A recent developer tutorial breaks down the concept of caching as a method of temporarily storing infrequently changing data in a fast medium, reducing repeated hits to the main database. Redis, an open-source in-memory NoSQL database, is highlighted as the most popular caching solution due to its speed advantage over traditional disk-based databases. The article notes two key limitations of Redis: RAM is significantly more expensive per gigabyte than hard disk storage, and data stored in RAM is lost when a server restarts. Beyond caching, Redis is shown to support use cases such as session storage, flash sale timers, background job queues, and write-buffering for high-volume events like video view counts. The tutorial also introduces three major caching patterns, with Cache-Aside described as the simplest and most widely used approach for read-heavy applications.
