high severity August 18, 2024 · 3 min read Unverified claim — what this is

PER4MANCE Listed by dragonforce Ransomware Group

If you are a customer of Per4Mance, here’s what is being claimed, and what it would mean for you.

Per4Mance was listed on DragonForce's leak site. DragonForce claims to have stolen internal data. This is the group's claim, not a confirmed finding.

PER4MANCE Listed by dragonforce Ransomware Group

PER4MANCE, the Czech systems integrator founded in 1995, appeared on the DragonForce ransomware leak site on August 18, 2024. The listing states that internal files were exfiltrated during a ransomware attack. The company has not yet published its own breach notification, so the exact number of people whose data may be exposed remains unknown.

Already exposed?
You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Primary Disclosure Details

The DragonForce leak site lists PER4MANCE as a victim and claims the company’s internal files were taken. The entry does not specify the volume or types of data stolen beyond claiming that files were exfiltrated. No ransom amount or payment deadline is shown in the public listing. The disclosure originates directly from the attackers’ data-leak platform, which ransomware.live mirrors for visibility.

PER4MANCE is headquartered in Brno and has built relationships with major technology vendors while serving large corporate clients across the Czech Republic. Any customer contracts, employee records, or partner agreements stored on the compromised systems could therefore be at risk, although the leak site itself does not itemise the contents.

Why This Matters for You and Your Family

When a company that supplies technology infrastructure to other organisations is breached, the ripple effects reach ordinary people. If you or any member of your family works for one of PER4MANCE’s clients, your payroll data, contact details, or even credentials used inside those organisations may have been stored on the affected systems. Even if you have no direct connection to the company, stolen internal files often contain spreadsheets that list vendors, partners, and customer contacts—information that can be used to target you with phishing or identity fraud later.

Internal files exfiltrated in ransomware incidents frequently include employee personal data, contracts, and correspondence. Once that material surfaces on a leak site, it stays available to identity thieves, fraudsters, and other criminals for years.

Doxxing and Identity-Chain Risks

Leaked internal documents rarely stop at one company. They often contain email addresses, phone numbers, and references to third-party systems that link employees, contractors, and client contacts together. Attackers and opportunistic criminals then combine this information with data from earlier breaches to build detailed profiles. A single leaked work email can expose your personal accounts if you have reused passwords or security questions. Children’s gaming accounts are especially vulnerable because the same family address or parent email is frequently used to register them, creating a direct path from corporate breach to home networks and online identities.

DragonForce’s Known Track Record

Public reporting attributes DragonForce with emerging in late 2023 as a ransomware operation that combines double-extortion tactics with aggressive data leaks. The group typically gains initial access through phishing, remote-desktop vulnerabilities, or compromised credentials, exfiltrates sensitive files before encrypting systems, then posts samples on its leak site to pressure victims. Notable prior targets have included organisations across Europe and North America, though exact victim lists fluctuate as some negotiate removal of their data. The group’s playbook emphasises public shaming when payments are not made, often releasing additional batches of stolen files over time.

What to do

  • Run a DoxxScan to map every link between your work and personal emails, phone numbers, and real-world identity so you can see exactly what this incident may have exposed.
  • Rotate any password you used at PER4MANCE or its client organisations anywhere it has been reused, and switch on 2FA with an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours instead of months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts which often chain back to the same addresses and parent credentials.
  • Let remediation specialists handle data-broker takedown requests and removal of any exposed personal documents on your behalf.

The breach of PER4MANCE shows once again that supply-chain technology providers hold data that can affect thousands of ordinary families. Acting quickly on credential hygiene and identity mapping limits how far attackers can travel down the chain. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes children’s gaming accounts vulnerable to cascading takeovers.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
