  • Nobody Hacked the Firewall: Inside the Year Identity Became the Whole Battlefield

    This story was originally published on HackerNoon at: https://hackernoon.com/nobody-hacked-the-firewall-inside-the-year-identity-became-the-whole-battlefield.


    Identity, not firewalls, is now the real cybersecurity perimeter, as state actors and social engineering groups exploit trust to breach organizations.

    Modern cyberattacks are no longer focused on breaking firewalls or exploiting network vulnerabilities — they target identity itself. Campaigns like Salt Typhoon show how nation-state actors can remain undetected inside telecom infrastructure for years by exploiting trusted systems like lawful intercept backdoors. Meanwhile, groups like Scattered Spider achieve similar impact using pure social engineering, tricking help desk staff into resetting MFA and granting access without any malware. Together, these threats reveal a fundamental shift in cybersecurity: the weakest link is no longer the system, but the moment human or process trust is granted to a false identity.

  • Your Build Pipeline Is the New Perimeter, and It Just Learned to Replicate Itself

    This story was originally published on HackerNoon at: https://hackernoon.com/your-build-pipeline-is-the-new-perimeter-and-it-just-learned-to-replicate-itself.


    CI/CD pipelines have become active attack surfaces, as supply chain worms and token theft turn software delivery into self-replicating malware vectors.

    Modern CI/CD pipelines are no longer passive delivery systems — they’ve become high-value attack surfaces where trust assumptions are routinely exploited. Incidents like the tj-actions GitHub Actions compromise show how mutable version tags can silently redirect trusted workflows into executing attacker-controlled code. Meanwhile, npm supply-chain worms such as Shai-Hulud demonstrate a more advanced threat: self-replicating malware that propagates through stolen publish tokens, harvesting credentials and reinfecting downstream systems without further human input.
    Across 2025–2026, the trend is clear: open-source ecosystems (npm, PyPI, GitHub Actions) are being hit by fast-moving, automation-driven attacks where compromise windows shrink from days to minutes. The result is a structural shift in security posture — where dependency integrity, token hygiene, and CI/CD hardening are no longer best practices, but survival requirements.

  • Trust by Default: The Five API Mistakes Driving Every Major Breach Right Now

    This story was originally published on HackerNoon at: https://hackernoon.com/trust-by-default-the-five-api-mistakes-driving-every-major-breach-right-now.


    Five recurring API security flaws behind modern breaches—BOLA, broken auth, data exposure, SSRF, and inventory issues—explained via real-world cases.

    Most API breaches don’t come from advanced hacking techniques—they come from repeated, basic design failures. Across recent real-world incidents, five issues dominate: broken object-level authorization (BOLA), weak authentication, excessive data exposure, misconfiguration/SSRF, and poor API inventory management. These problems persist because APIs are built to trust requests by default. Until that changes, the same security failures will continue causing large-scale breaches across industries.

  • Building a Fake Solar Plant for Cybersecurity Research — Part 3

    This story was originally published on HackerNoon at: https://hackernoon.com/building-a-fake-solar-plant-for-cybersecurity-research-part-3.


    Defensive lessons from an exposed ICS/IoT honeypot: keep OT protocols private, block egress, kill default credentials, segment networks, and log behaviour.

    An exposed energy-themed honeypot gets discovered in under an hour, then faces continuous brute force, web scanning, and protocol-aware Modbus reconnaissance, with zero write or control attempts. Part 3 turns those findings into defence. The same structural controls that stop commodity scanning also shrink the targeted tail: keep OT protocols and management planes off the public internet, block egress by default, remove default credentials, segment IT from OT, and log behaviour instead of bare port contact. Most of it is network architecture, not detection wizardry.
