5 Red Team Tools I Actually Use

Notes on capabilities, operational constraints, and defensive/ethical guidance.

Important — legal & ethical use:

All tools listed below have legitimate research and defensive uses, but they are dual‑use and can be misused. Only use them on systems you own or have explicit written authorization to test. This article focuses on defense, detection, and safe lab use.

1. Cobalt Strike (Beacon & Adversary Simulation)

Vendor

Commercial adversary-simulation platform; used for red team operations and purple-team exercises.

What it does: command-and-control framework, post-exploitation tooling, and emulation of advanced adversary tradecraft.

When I use it: controlled, authorized engagements for emulating persistent adversaries and testing detection capabilities at scale.

Defensive notes: monitor for unusual beaconing patterns, long‑lived TLS sessions to unknown endpoints, and PowerShell/WMIC process chains. Implement egress filtering and network-based detection signatures.

Pros: realistic adversary simulation, rich toolset for reporting. Cons: commercial, expensive, and often targeted by defenders as a red flag.

2. Metasploit Framework

Open-source exploitation framework (with commercial Pro edition) — staple in labs for learning exploitation and post-exploit automation.

What it does: modular exploit and payload delivery, auxiliary scanners, and post-exploitation modules.

When I use it: lab exercises, proof-of-concept research, and to validate detection rules against known exploit patterns.

Defensive notes: deploy honeypots, log exploit attempts, and correlate exploit signatures with IDS/IPS events. Ensure hosts have up-to-date patching and mitigations.

Pros: large community, many modules; Cons: noisy on the network and easily detected if not tuned for stealth.

3. BloodHound (Active Directory Enumeration)

Graph-based AD analysis to identify privilege escalation paths and misconfigurations.

What it does: collects AD objects/relationships and visualizes attack paths between users, groups, and computers.

When I use it: after domain enumeration in labs or during engagements where AD assessment is authorized.

Defensive notes: monitor LDAP querying patterns, unusual high-volume enumeration, and constrain unnecessary privileges. Harden ACLs and use group policy to minimize misconfigurations.

Pros: exposes complex attack paths quickly; Cons: requires careful data handling and explanation to stakeholders.

4. Wireshark & Scapy (Network Analysis & Packet Crafting)

Packet capture, deep protocol inspection, and low-level packet crafting for defensive analysis and testing.

What it does: Wireshark inspects packet captures; Scapy crafts and sends arbitrary packets for testing firewalls, IDS, and protocols.

When I use it: diagnosing protocol issues, validating detection signatures, and testing how devices respond to malformed or crafted traffic.

Defensive notes: ensure PCAP retention and indexing for rapid detection. Be careful sending crafted traffic on production networks — prefer isolated lab environments.

Pros: indispensable for protocol-level understanding; Cons: crafting packets can be dangerous on live networks if misused.

5. Flipper Zero & Proxmark (RF / Embedded)

Portable hardware tools for testing RFID, sub-GHz, and simple embedded protocols.

What it does: Flipper Zero is a multi-tool for sub-GHz, RFID, NFC, Bluetooth LE sniffing; Proxmark offers deeper RFID frame analysis and emulation.

When I use it: physical security assessments and lab experimentation with access controls and IoT devices (with authorization).

Defensive notes: physical access controls, RFID tag rotation, and RF monitoring help mitigate these attack vectors. Follow local laws when using RF tools.

Pros: portable and practical for wireless/physical assessments; Cons: legal constraints and operator learning curve.
