A comprehensive, step-by-step guide for deploying applications on Replit to production environments. It covers crucial best practices, including configuring deployment settings, managing environment secrets, implementing robust health checks, handling global errors, setting up custom domains, and defining rollback strategies. Essential for developers preparing an app for a live launch or scaling up.

This comprehensive guide details the use of FFUF, a fast web fuzzer written in Go. It is designed for advanced security penetration testing, providing techniques for content discovery, subdomain enumeration, parameter fuzzing, and POST data testing. Learn to master the FUZZ keyword, advanced filtering, and auto-calibration to efficiently identify hidden paths and potential vulnerabilities in web applications.

A comprehensive guide for analyzing PCAP files captured during malware execution. It demonstrates advanced techniques using Wireshark, Zeek, Suricata, and Python (scapy) to identify Command and Control (C2) communications, data exfiltration channels, Domain Generation Algorithms (DGA), and periodic beaconing patterns. Essential for malware reverse engineering and network threat detection.

This guide outlines the process of passive external reconnaissance using Open Source Intelligence (OSINT) techniques. Users can map an organization's digital footprint by gathering comprehensive data, including DNS records, subdomains, certificate transparency logs, social media profiles, and leaked credentials. It is critical for the planning phase of penetration testing, asset mapping, or preparing for social engineering, all without actively interacting with target systems.

This guide details comprehensive detection methods for DCSync attacks (MITRE T1003.006) in Active Directory. Attackers abuse legitimate directory replication protocols to extract sensitive password hashes. Detection relies on auditing Windows Event ID 4662 for unauthorized access attempts to critical Directory Service GUIDs, specifically flagging non-domain-controller accounts attempting replication calls. Essential for threat hunting and incident response.

Executes authorized, advanced attack simulations against Active Directory environments to identify critical misconfigurations, weak credentials, and exploitable trust relationships. Utilizing industry tools like BloodHound, Mimikatz, and Impacket, this process simulates complex attacks such as Kerberoasting, Golden Ticket forging, and domain compromise path analysis, helping organizations validate their security posture against real-world threats.

This guide details the exploitation of the Active Directory Certificate Services (AD CS) ESC1 vulnerability. By leveraging misconfigurations, an attacker can request certificates impersonating high-privileged users (e.g., Domain Admins). The workflow covers AD enumeration, forging certificates with arbitrary Subject Alternative Names (SANs), authenticating via PKINIT, and ultimately escalating domain privileges using tools like mimikatz. Essential for authorized red team and penetration testing.

This guide details the exploitation chain for noPac, combining CVE-2021-42278 (sAMAccountName spoofing) and CVE-2021-42287 (KDC PAC confusion). It demonstrates how an attacker can escalate from a standard domain user to Domain Admin by manipulating Active Directory tickets and performing DCSync. Primarily used in authorized red-teaming and penetration testing to validate domain security.

This guide details the exploitation of the critical Zerologon vulnerability (CVE-2020-1472) in Active Directory Domain Controllers. It demonstrates the methodology for resetting the DC machine account password to empty, achieving full domain compromise. Subsequent steps include dumping domain credentials using DCSync. Essential for authorized red-teaming and security validation.

This guide details how to hunt for DCSync attacks (MITRE ATT&CK T1003.006) in Active Directory environments. It focuses on analyzing Windows Security Event ID 4662, specifically looking for DS-Replication-Get-Changes requests originating from non-domain-controller accounts. This technique is critical for incident response, purple teaming, and detecting unauthorized credential theft via Active Directory replication abuse.

This skill provides a structured methodology for threat hunting DNS-based persistence mechanisms. It detects unauthorized changes such as DNS hijacking, dangling CNAME records enabling subdomain takeover, wildcard DNS abuse, or unauthorized NS delegation modifications. By utilizing passive DNS history (e.g., SecurityTrails API) and auditing cloud DNS logs (Route53, Azure, Cloudflare), users can identify persistent attack vectors that survive traditional remediation efforts.

A comprehensive guide to identifying covert data exfiltration channels using Zeek logs. This technique analyzes DNS traffic for high-entropy subdomains, unusually long query lengths, abnormal record types (TXT/NULL), and excessive query volume, which are key indicators of malicious DNS tunneling or command-and-control (C2) activity.
