Disclosing Observer

DNS sinkholing does not erase abuse infrastructure but captures it at the moment of intervention. This post shows how passive DNS can be used to reconstruct pre-takedown organization from that boundary.

Using leaked internal data, this post reconstructs how the sanctioned bulletproof hoster Media Land organized users, subscriptions, and address space, revealing supply-chain links to ransomware operations.

Responsible vulnerability disclosure begins with character. This post argues that honesty, restraint, and care matter more than formal permission when assessing the ethics of unsolicited hacking.

Turla’s Pelmeni wrapper illustrates how flawed cryptographic design in malware can expose payloads. This post dissects how a weak pseudorandom generator enabled Kazuar payload recovery and what this means for threat intelligence.

Even after patching, many edge devices remain compromised. This post examines how ethical scanning can uncover persistent backdoors left behind.

When one nation hoards cyber capabilities, others feel compelled to follow. This post examines how U.S. zero-day retention policy risks triggering an arms-race dynamic that weakens global security.

Most vulnerabilities never make headlines. Botched disclosures do. This post examines how attempts to silence researchers can amplify attention and risk rather than contain it.

Sanctions checks in ransomware cases depend on indicators that change faster than policy can keep up. This post examines how attribution uncertainty turns compliance into a burden for victims rather than a constraint on attackers.
