The first Enterprise Season continues the ACT II: Proxy Crown with a new Sherlock, Relay of Deceit.

This time, the focus shifts to the software supply chain. Hidden inside what appears to be a legitimate npm package is malicious code designed to evade review, perform host reconnaissance, and quietly exfiltrate sensitive data over DNS.

Players will practice how to:

CTF admins can now access scenario writeups directly from the Content Library while building an event. Instead of selecting challenges based only on titles, descriptions, and difficulty, admins can review the intended solution path before adding content, making it easier to understand what each challenge tests and whether it fits the event's goals.

Choose challenges with more confidence and match content to your goals by validating that each challenge tests the right skills for your audience and training objectives.

HTB's first Enterprise Season enters its next phase.

Your search for Arodor's proxy network now leads into a compromised settlement environment, where exposed identities and excessive cloud permissions hide a chained privilege-escalation path.

Take on Silent Market Raid, a new AWS Challenge where you'll enumerate cloud resources, abuse IAM trust relationships, and uncover how seemingly harmless disclosures can lead to complete compromise.

Continue the mission and begin Act II: Proxy Crown.

Need to catch up?

Complete the scenarios from Act I: Gridfall Signals.

We have added a brand-new Satellite category, featuring nine progressive Challenges created in direct partnership with aerospace cybersecurity firm VisionSpace.

This track covers satellite system architecture, main communication protocols, and common attack vectors. Content ranges from Very Easy to Hard difficulty, offering practical exposure to realistic scenarios inspired by real-world satellite software and infrastructure. Available now across both HTB Labs and the Enterprise Platform.

Threat Range events are now more flexible.

Admins and Event managers can now customize alert dispatch pacing and response-time SLAs, making it easier to tailor exercises to different team skill levels, operational workflows, and event durations.

What's new?

Use HTB's recommended defaults or align timings with your organization's internal SLAs and operating procedures.

AI models do not operate in isolation. An agent consists of the model paired with host-side code that validates tool proposals, communicates with external systems, and controls when the execution loop terminates. Relying strictly on system prompts for security leaves systemic vulnerabilities that attackers can exploit.

In this new Medium-difficulty module available on HTB Academy and HTB Enterprise, you will construct that host-side orchestration code yourself. You will learn how to enforce safety decisions there, not in the prompt.

Administrators can now control the sequence of content assigned to a Space, making it easier to build structured workforce development programs that guide learners through deliberate, role-aligned skills journeys.

From the Space’s Content tab, open Assigned Content. Enter mode to drag and drop content cards or update their numeric position fields, then make sure to Save your order selection.

Create deliberate learning paths across modules, challenges, labs, and Sherlocks.

We integrated 191 modules from LetsDefend into the HTB Academy library to expand our defensive and foundational cybersecurity curriculum. This launch increases HTB Academy's defensive content by more than 500%, making comprehensive blue team skills accessible under Tier 0 and Tier 1 access.

Key Updates:

A compromised mission operations environment has exposed weaknesses across cloud infrastructure, application security, and containerized workloads.

Deploy into Zeek, a new Linux Machine where you'll enumerate AWS resources, investigate LocalStack services, exploit a vulnerable Lambda function, and pivot from cloud access to full host compromise through Docker.

Continue Act I: Gridfall Signals and uncover the next piece of Arodor's campaign.

Following the acquisition of LetsDefend, we have massively expanded your defensive security training.

You can now develop and validate defensive capabilities through a broader combination of structured learning paths, hands-on investigations, and realistic SOC simulations across every stage of the cyber workforce journey.
