Red Team Tools

Red team tools help security professionals emulate real-world adversaries, identify exploitable attack paths, and evaluate whether security controls can prevent, detect, and respond to cyberattacks.

In 2026, professional red teaming extends beyond vulnerability exploitation. Attackers increasingly target identity infrastructure, abuse legitimate administration tools, and combine multiple techniques to move across hybrid environments.

An effective red team toolkit therefore includes reconnaissance utilities, Active Directory assessment tools, credential access frameworks, command-and-control (C2) platforms, and post-exploitation capabilities.

This guide examines 15 red team tools, explains where they fit into the attack lifecycle, maps representative behaviors to MITRE ATT&CK, and uses findings from the Picus Red Report 2026 and Blue Report 2026 to prioritize realistic testing.

What Are Red Team Tools?

Red team tools are applications and frameworks used during authorized security assessments to reproduce adversary tactics, techniques, and procedures (TTPs).

Unlike vulnerability scanners, which primarily identify potential weaknesses, red team tools help determine whether weaknesses can be combined into attack paths that threaten business-critical assets.

A typical enterprise red team engagement includes reconnaissance, initial access, privilege escalation, credential access, lateral movement, command and control, collection, and exfiltration.

The objective is not simply to execute an attack. It is to establish what an adversary could accomplish and whether defensive controls would interrupt or detect the activity.

15 Red Team Tools by Attack Phase

The following tools are grouped by their primary operational purpose. Their MITRE ATT&CK mappings represent example procedures, not every capability a tool supports.

Reconnaissance and Attack Surface Discovery

Nmap helps operators identify reachable systems, exposed ports, and services from a defined network position. Its results can reveal unnecessary exposure and inform subsequent testing.

OWASP Amass discovers external infrastructure and relationships between domains, subdomains, and associated assets. This is particularly valuable for organizations with distributed internet-facing infrastructure.

Together, these tools help establish what is visible and reachable. However, discovering an exposed service does not prove it is exploitable.

Identity Discovery and Active Directory Attack Paths

BloodHound CE uses collected identity data to identify potential privilege escalation paths. SharpHound collects Active Directory information, while AzureHound supports relevant cloud identity data.

A graph relationship represents a potential path, not proof that every step remains executable. Permissions, network segmentation, and security controls can affect the outcome.

NetExec, the community-maintained successor to CrackMapExec, supports authentication and administrative access assessment across enterprise protocols.

Impacket provides protocol-level utilities for evaluating Windows authentication and remote execution.

Certipy addresses Active Directory Certificate Services (AD CS), where insecure certificate templates and enrollment permissions can create privilege escalation opportunities.

Rubeus supports Kerberos-focused assessments, including testing conditions associated with Kerberoasting and ticket abuse.

These tools are especially relevant because identity misconfigurations can create attack paths even when individual endpoints have no directly exploitable software vulnerability.

Credential Access and Privilege Escalation

Mimikatz is associated with Windows credential access techniques and is used in authorized assessments to evaluate credential protection.

Rubeus and Certipy test different identity attack surfaces: Kerberos tickets and certificate-based authentication.

The distinction between credential access and credential use matters. Obtaining credential material does not automatically establish that an attacker can use it to reach a sensitive system.

Security teams should therefore measure credential exposure and subsequent access separately.

Command and Control, Exploitation, and Exfiltration

Cobalt Strike remains a commercial framework for coordinated adversary emulation. Sliver provides open-source cross-platform C2 capabilities, while Mythic supports modular agents and communication profiles.

Metasploit helps validate selected vulnerabilities under controlled conditions. Rclone can simulate data transfers to approved cloud destinations, and Hashcat supports offline password-strength assessment.

Wireshark primarily supports packet analysis and test verification rather than offensive execution.

A C2 framework's presence alone does not establish which techniques were executed. Operators must document the specific action, configuration, communication behavior, and defensive response.

What Changed in Red Teaming Tools in 2026?

Several developments distinguish a current toolkit from older red team tool lists.

Identity attack paths now extend beyond traditional Active Directory. BloodHound CE supports broader identity analysis through its collection ecosystem and graph capabilities.

NetExec has superseded CrackMapExec as the maintained community project. Current articles should reflect this rather than treating both as equally maintained alternatives.

C2 frameworks continue evolving. Cobalt Strike, Sliver, and Mythic remain relevant to professional adversary emulation, but their capabilities, versions, and supported agents differ.

MITRE ATT&CK terminology has changed. ATT&CK v19 separated the former Defense Evasion tactic into Stealth (TA0005) and Defense Impairment (TA0112). Current assessments should use the appropriate taxonomy.

Most importantly, red teams increasingly need to demonstrate defensive outcomes rather than simply report that a tool executed successfully.

Red Report 2026: Which Attacker Behaviors Should Red Teams Prioritize?

The Picus Red Report analyzes malware behavior to identify frequently observed MITRE ATT&CK techniques.

The 2026 research analyzed more than 1.1 million malicious files and 15.5 million malicious actions from 2025.

These findings have direct implications for red team planning.

Process injection warrants behavioral testing beyond known executable signatures. Security teams should evaluate whether suspicious process and memory activity is prevented or detected.

Command and scripting interpreter activity supports testing PowerShell and other interpreters relevant to the environment. The 27% figure describes the parent ATT&CK technique, not PowerShell specifically.

Credentials from Password Stores highlights the importance of testing browser and application credential protection rather than relying exclusively on traditional credential-dumping scenarios.

Application Layer Protocol reinforces the need to test suspicious C2 behavior over protocols commonly permitted in enterprise environments.

These percentages describe technique prevalence within the analyzed malware corpus. They are not tool popularity rankings, organizational compromise rates, or attack success probabilities.

Blue Report 2026: What Happens When Defenses Face Simulated Attacks?

The Picus Blue Report 2026 examines security-control effectiveness across more than 338 million attack simulations conducted between January and June 2026.

These findings reveal important differences between blocking an attack, recording activity, and generating actionable alerts.

The Prevention–Detection Gap

Although prevention reached 69%, only 14% of tested activity generated alerts.

This matters because a control may allow suspicious behavior while producing telemetry that never becomes an actionable detection.

For example, a red team may execute a remote administration technique that generates endpoint events without triggering the expected SIEM alert.

That outcome is different from a technique being prevented.

Post-Compromise and Exfiltration Exposure

The 37% post-compromise prevention result highlights the need to assess what happens after an attacker gains an initial foothold.

Similarly, the 7% exfiltration prevention score suggests that controlled data-transfer testing deserves explicit attention.

Red teams should therefore evaluate credential access, lateral movement, collection, and exfiltration rather than ending assessments after demonstrating initial access.

The Red Report measures observed malware behaviors; the Blue Report measures security-control outcomes in simulation datasets. Their percentages must remain separate.

How to Measure Red Team Effectiveness

A successful red team engagement requires more than a list of executed tools.

Each test should produce evidence across five dimensions:

An unsuccessful test caused by missing prerequisites is not proof of prevention. Similarly, an event appearing in a log is not evidence that an analyst received an alert.

For meaningful remediation, teams should record the ATT&CK technique, exact procedure, tool version, starting privileges, observed result, and retest outcome.

This makes findings reproducible and prevents a single successful detection from being misrepresented as comprehensive ATT&CK coverage.

Red Teaming, Agentic Pentesting, BAS, and Exposure Validation

Individual red team tools support specific operations, but no single tool establishes continuous security coverage.

Human-led red teaming provides creativity and contextual reasoning when investigating complex attack paths.

Deterministic automated pentesting follows repeatable procedures, making it useful for recurring assessments and remediation verification.

Agentic pentesting adds adaptive decision-making, allowing AI agents to evaluate findings and select subsequent testing actions.

However, agentic pentesting has limitations. Live exploitation can only assess assets that are reachable, authorized for testing, and safe to exploit. Some vulnerabilities also lack a suitable working exploit.

Picus addresses these different requirements through three complementary capabilities:

• Autonomous Pentesting combines agentic and deterministic approaches to validate attack paths.
• Breach and Attack Simulation (BAS) evaluates whether security controls prevent, log, and detect attacker behaviors.
• Exposure Validation uses security-control evidence and asset context to assess exposures that cannot safely undergo live exploitation.

These methods produce different forms of evidence. A vulnerability confirmed exploitable through execution is not equivalent to an exposure assessed as likely exploitable from control and environment evidence.

Picus Swarm uses five specialist agents orchestrated by Numi AI to support discovery, exploitation, validation, mobilization, and reporting.

Together, these capabilities connect offensive testing with remediation prioritization and revalidation.
