XXE injection abuses XML parsers that resolve external entities, letting attackers read local files and exfiltrate data out-of-band. This post walks through a direct file-read attack and a blind OOB exfiltration technique with real payloads and tool output.
BloodHound maps Active Directory attack paths that attackers exploit and defenders miss. This guide walks through real SharpHound collection, Cypher queries, and ACL remediation with actual command output at every step.
Attackers used a single cron entry to maintain access to a fintech build server for 47 days. Learn how to find malicious cron jobs across all seven persistence locations on Linux, and lock down cron before the next attacker does the same to you.
AI copilots are running with secrets in their environment and no injection defenses — a combination attackers are actively exploiting. Here’s how to enumerate your agent’s real access, test for prompt injection with Garak, and enforce runtime tool policies before something goes wrong.
A solid forensics CTF methodology beats raw tool knowledge every time. Learn how to triage disk images, extract memory artifacts with Volatility, and decode hidden flags from PCAP files — with real commands and output at every step.
Most teams use Burp Suite Pro at 20% of its capability. This post walks through active scan tuning, Cluster Bomb credential attacks, and JWT tampering with real commands and tool output — so you can run a sharper assessment today.
Nobelium never dropped an EXE on most victim machines — they used PowerShell and WMI to operate entirely in memory. Here is exactly how living-off-the-land attacks work and what defenders need to look for right now.
SSRF vulnerabilities let attackers route requests through your server to internal services, cloud metadata endpoints, and anything else the host can reach. Learn how to find vulnerable parameters, pull AWS credentials via IMDSv2-disabled EC2, and bypass naive input filters with real commands and output.
AMSI patching, exclusion abuse, and ETW blinding are the three Windows Defender bypass techniques active in red team engagements right now. This post walks through real commands and tool output so you know exactly what to look for — and how to stop it.
eBPF lets you attach security probes directly to Linux kernel hooks with near-zero overhead — no modules, no reboots. Learn how to catch privilege escalation and sensitive file access in real time using bpftrace and Falco, with commands you can run on a production host today.
A threat group sent 40,000 personalized phishing emails in 72 hours using an LLM pipeline — and got triple the click rate. Here’s how the attack works, how to detect it in your mail stack, and one thing you can do right now to measure your exposure.
Cryptography CTF challenges recycle the same attack surfaces — Caesar shifts, XOR key reuse, and weak RSA — across nearly every competition. Learn to recognize them fast with real Python commands, tool output, and a clear path from ciphertext to flag.
