How ICS and SCADA environments actually get breached, network segmentation, weak authentication, unpatched legacy software, thin monitoring, and vulnerable remote access, paired with the real incidents (Triton, Mirai, WannaCry, Stuxnet, Oldsmar, the Ukrainian grid attack) that show each failure mode in production.
Threat hunting is the proactive search for adversary activity that automated detections missed. This post covers the hunting loop (hypothesis, investigation, verification, feedback), the four standard hunting surfaces (network, endpoint, log, threat intelligence), the current tooling (Zeek, Suricata, Velociraptor, OSQuery, Sigma, MITRE ATT&CK), and the operational patterns that turn one-off hunts into a detection engineering program.
Wireshark and tcpdump are the two packet-analysis tools every network defender, incident responder, and pen tester ends up using. This post covers modern capture workflow (non-root operation, display and BPF filters, TLS decryption via SSLKEYLOGFILE, SSH remote captures) with concrete examples for both tools.
Serverless functions shift infrastructure responsibility to the provider but leave application code, IAM policies, and resource configurations in your hands. This post covers the common misconfiguration classes (function-level, resource-level, infrastructure-level), the tooling that catches them (Checkov, Prowler, ScoutSuite, Trivy), and the attack surfaces unique to serverless (event injection, denial-of-wallet).
This article explores advanced object-oriented programming concepts in Python, such as decorators, inheritance, abstract base classes, composition, aggregation, and properties, with practical code examples tailored for security engineers building analysis, detection, and instrumentation tools.
A working overview of the NIST Cybersecurity Framework (six functions after CSF 2.0), ISO/IEC 27001:2022 (10 clauses plus 93 Annex A controls in 4 themes), and CIS Controls v8/v8.1 (18 controls organized by Implementation Group), including how they fit together and where each earns its keep in real security programs.
This article provides a comprehensive overview of wireless security, including technical details of wireless networking, best practices for securing wireless networks, common attacks, social engineering tactics, wireless network penetration testing, regulatory compliance, and the future of wireless security.
This article explores the importance of TTP (tactics, techniques, and procedures) analysis in detecting and mitigating cyber threats, including its role in guiding investigations, assisting in attribution, and informing predictive analysis, using examples of TTP analysis in well-known attack campaigns.
How application layer firewalls inspect traffic beyond IP and port, protocol analysis, content filtering, application identification, behavioral analysis, and deep packet inspection, plus the tools for testing whether one actually holds up.
A defender’s field guide to threat hunting and incident response: behavioral analysis and UEBA, EDR, network traffic analysis with Zeek, the ELK stack, Sysmon on Windows, and the commercial SIEM/EDR/NSM tooling you actually run. Plus what Target, Equifax, and NotPetya taught defenders about detection.
A working operator’s view of ransomware in 2026. How the RaaS model splits the work between operators and affiliates, the double- and data-only extortion patterns that replaced “just encrypt the files,” the state of the ecosystem after Operation Cronos took down LockBit and ALPHV exit-scammed itself, what reverse engineering a current sample actually looks like, and the incident response sequence when the ransom note lands.
