I’ve spent 25+ years in business warfare — buying troubled companies, turning them around, doing private security consulting, and researching cybersecurity from the operator’s side, not the engineer’s. And I can tell you this with total confidence: when small businesses get hacked, it’s almost never some hoodie-wearing genius cracking encryption. It’s a founder reusing a password. It’s an admin clicking a link. It’s someone handing over the keys because the “IT guy” on the phone sounded convincing.

I reported two OAuth credential exposure flaws in the official MCP Python and TypeScript SDKs, now tracked as CVE-2026-115563 and CVE-2026-104850. A malicious MCP server could manipulate OAuth discovery, causing affected clients to send secrets, refresh tokens, or other credentials to attacker-controlled endpoints. Both SDKs have patches, but some integrations also need explicit issuer binding and updates to stored credentials.

Assessing Common-Mode Failures in Redundant Power Distribution Systems
This story was originally published on HackerNoon at: https://hackernoon.com/assessing-common-mode-failures-in-redundant-power-distribution-systems. Two power sources don't guarantee resilience. Learn how shared transfer switches, control systems, and maintenance dependencies create hidden failure risks. Check more stories related to cybersecurity at: https://hackernoon.com/c/cybersecurity.

Redundant power supplies don't necessarily make critical infrastructure resilient. Shared transfer switches, control circuits, physical pathways, and maintenance procedures can create single points of failure even when multiple power sources are available. Through a hypothetical 700-kW facility, the article demonstrates how a failed transfer controller can interrupt service despite adequate backup capacity. It outlines a practical method for identifying hidden dependencies across electrical capacity, protection, controls, physical infrastructure, and human operations.

Immutable Backup Architecture Explained: How WORM and Air-Gapped Storage Actually Stop Ransomware
This story was originally published on HackerNoon at: https://hackernoon.com/immutable-backup-architecture-explained-how-worm-and-air-gapped-storage-actually-stop-ransomware. Immutable storage blocks deletion, but a stolen admin identity can still do damage. Follow one credential through WORM, air gaps and quorum approval.

This story was written by: @pallavirani. Learn more about this writer by checking @pallavirani's about page, and for more stories, please visit hackernoon.com. Ransomware crews go after your backups first, because a working backup means you don’t have to pay. Immutable storage can block deletion, but it only helps if a stolen login also can’t control the backup console, approve its own deletions or reconnect the offline copy. This piece follows one stolen credential through each layer to show where it stops. A simple restore test then shows whether the surviving copy can actually run your application.
