Manufacturing (Pipelines & Motor Design)

Dark Web Data Leak Investigation for a German Manufacturing Company

Confidential. Leaked. Already for sale on the dark web, before the company even knew it had been breached. Payatu's threat intel team tracked a German manufacturer's stolen data across 11 dark web marketplaces, from XSS to Shadow Leaks, ran it down to a Telegram channel called Industrial Spy, and helped shut the leak for good.

the challenge

Why the client called us in

The client, a well-recognized German manufacturer of pipelines and manual motor designs, received intel that some of its private data had been leaked on the dark web. With no way to independently confirm or scope the leak, the company could not tell how much data was exposed, where it had surfaced, or how to stop it from spreading further. It approached Payatu to investigate the leak and advise on how to prevent a repeat.

  • Confirm whether the reported data leak was real and locate it
  • Establish the scope of what had been exposed
  • Get practical recommendations to prevent future leaks

scope of engagement

What was in scope

  1. Round-the-clock monitoring of dark web portals
  2. Testing multiple parameters across dark web search engines, darknet marketplaces, ransomware sites, web portals, marketplaces, forums, and chat servers
  3. Gathering the last three months of data for any possible mentions of the client
  4. Collecting and structuring the search results for analysis

Our Approach

How Payatu ran the engagement

01

Threat landscape mapping
Payatu Bandits began by understanding the client's threat landscape and building a plan before starting the dark web investigation.

02

Keyword categorization and marketplace search
The team categorized keywords that could be used to publish the client's data on the dark web, then searched and analyzed them across 11 marketplaces, including Ramble, Breached Forum, XSS, Shadow Leaks, and Industrial Spy.

03

Multi-source dark web search
Payatu expanded the search to 10 additional sources, among them Ahmia, NulledBB, Antimigalki, Raddle, Shadow, and Dark Leak Market, and monitored 6 active ransomware sites, including Alphv, Cuba, Everest, Hive, Lockbit 3.0, and AvosLocker.

04

Leak confirmation and reporting
The team confirmed the leak, traced where it had surfaced, and delivered findings along with mitigation recommendations to the client.

Key findings

What we found

Data Leak Confirmed
Payatu identified a data leak posted a couple of months earlier on a dark web marketplace, containing the client's private data.
Cross-Platform Exposure
The same leaked data was also found circulating on a Telegram channel called Industrial Spy, extending the exposure beyond the original dark web posting.

Results and Impact

Working against a time-sensitive deadline and the slow, complex nature of dark web research, Payatu confirmed the leak, traced its source, and gave the client a clear picture of what had been exposed and where. The team also handed over practical steps to close the gaps that allowed the leak to happen.
