None of this replaces good backup hygiene, offline copies, or incident response planning. But it does move the fight to a stage where you have more leverage: instead of racing to restore from whatever snapshot survived, you're dealing with an attacker who never had a normal filesystem to attack in the first place.

  Stop Writing Incident Reports, Start Writing Case Law: Gaps from OpenAI and Hugging Face Disclosure 28.07.2026 30min

  This story was originally published on HackerNoon at: https://hackernoon.com/stop-writing-incident-reports-start-writing-case-law-gaps-from-openai-and-hugging-face-disclosure.

An OpenAI model escaped its test sandbox, chained two zero-days, and breached Hugging Face to cheat on a benchmark. The capability was new; the failure mode was not. Written up as a legal case, the incident breaks into five elements, and four of them resolve on security principles published between 1966 and 1988. The fifth, a defender's own AI tooling refusing to analyze its own attack logs, maps to no existing rule and needs a new one.

  3 Ways JWTs Get Forged, and the One Rule That Stops Them All 27.07.2026 6min

  This story was originally published on HackerNoon at: https://hackernoon.com/3-ways-jwts-get-forged-and-the-one-rule-that-stops-them-all.

I walk through the three JWT attacks I actually test for: changing the algorithm to none, cracking weak HMAC secrets offline, and confusing an RS256 verifier into accepting an HS256 token signed with the public key. All three exploit weak assumptions in how the server verifies the token.

  Virus Protection for Phone: Why Modern Smartphones Need More Than Antivirus 25.07.2026 29min

  This story was originally published on HackerNoon at: https://hackernoon.com/virus-protection-for-phone-why-modern-smartphones-need-more-than-antivirus.

Traditional antivirus alone is no longer enough. Modern mobile threats often bypass signature-based detection using spyware, banking trojans, phishing, and zero-click techniques. Behavioral detection is becoming the new standard. Monitoring application behavior, permissions and system anomalies helps identify threats that conventional antivirus solutions may miss. Security extends beyond the device. Protecting communications, cloud infrastructure and authentication mechanisms is just as important as detecting malware. Layered protection is essential. Effective virus protection for phone combines antivirus, anti-spyware technologies, secure communications and continuous monitoring into a single security strategy. The future of mobile security is proactive, not reactive. The most effective solutions stop attacks by recognizing suspicious behavior before sensitive data is compromised.

  When PowerShell Said "Failed," tcpdump Said Why 23.07.2026 9min

  This story was originally published on HackerNoon at: https://hackernoon.com/when-powershell-said-failed-tcpdump-said-why. A failed PowerShell download, a missing packet, and the tcpdump commands that proved where the connection really died — host firewall, not the attacker.

A malicious PowerShell script on a compromised app server tried to download a second-stage payload and failed — but the error message couldn't say whether the attacker's server refused it, a firewall blocked it, or it never left the host. Four tcpdump commands settled it: the request never reached the network at all. This piece walks through the core tcpdump syntax (reading captures, payload inspection, host/port filtering, TCP flag matching) using a clean sample file, then applies it to a real incident-response case to show why packet-level visibility catches things host logs structurally can't.

  Two-Thirds of the Top Million Domains Can Still Be Spoofed 22.07.2026 12min

We analysed daily DNS snapshots of the Tranco top-1M. Of 659,259 mail-receiving domains, 67.4% publish no enforced DMARC policy, ~96,000 run "monitoring mode" that reports to no one, and the enforcement share is declining — a side effect of the 2024–2025 bulk-sender mandates that made p=none the ceiling.

  The $2 Trillion Compliance Problem: Why Regulated Industries Need a Unified AI Approach 22.07.2026 9min

  This story was originally published on HackerNoon at: https://hackernoon.com/the-$2-trillion-compliance-problem-why-regulated-industries-need-a-unified-ai-approach.

The U.S. spends $2.15 trillion a year on regulatory compliance, and after years of building compliance systems, I think I know why: every regulated industry rebuilds the same infrastructure from scratch. Finance, healthcare, and corporate communications all solve an identical problem (messy data in, rules applied, audit trail out) with completely separate tools, while 77% of compliance teams still work manually. The fix is three shared layers: a universal data pipeline, a context-aware analysis engine, and a regulatory change tracker. Nobody has built them as one platform because vendors organize by vertical, not by problem. I'm working on changing that, and I have a prototype running rules from four unrelated regulatory domains through a single engine.

  AI Agents & Non-Human Identities: Why They Must Be IAM Users 21.07.2026 11min

  This story was originally published on HackerNoon at: https://hackernoon.com/ai-agents-and-non-human-identities-why-they-must-be-iam-users. AI agents and non-human identities must exist as first-class IAM users before they act. Start with auditability, access review, and governance in your IAM.

This story was written by: @sebastianmartinez. Learn more about this writer by checking @sebastianmartinez's about page, and for more stories, please visit hackernoon.com. AI agents should not run on secrets, tokens, shared service accounts, or borrowed human sessions. If they can access systems, interpret context, select tools, and trigger actions, they need stable, visible identities in IAM. Start simple: create directory users for meaningful agents, classify them as “Agent”, apply governance groups such as human-supervised or high-privilege, and govern them before they act.
