alge-stop.dk Listed by M3rx Ransomware Group

On May 6, 2026, Danish company Alge-Stop.dk appeared on the leak site of the m3rx ransomware group, with 73 GB of internal files and 7,100 documents listed as stolen.

Reported Details of the Breach

Public reporting indicates the attackers exfiltrated internal files from the company, which provides algae and moss removal services for roofs, walls, tiles, and paving stones. The data was posted on the m3rx ransomware leak site, accessible via the onion address hosted on ransomware.live. No confirmed customer list or personal data types have been publicly detailed, but the volume suggests a wide range of business records were taken. The company’s phone number, +45 22100211, appears alongside the listing.

Why This Matters for You and Your Family

When a local service provider like Alge-Stop suffers a breach, your personal information may be exposed even if you never shopped online. Homeowners who hired them for roof cleaning or driveway treatment often provided names, addresses, phone numbers, email addresses, and payment details. If those records were among the 7,100 files, the information may now be in the hands of criminals who sell or publish it. For ordinary families, this can lead to spam, identity theft, or targeted scams that feel personal because the attackers know where you live and what services you bought.

The Doxxing and Identity-Chain Risks

A single breach rarely stays isolated. Criminals combine the stolen company files with data from other sources to build detailed profiles. An address from an Alge-Stop invoice can link to your social-media accounts, children’s names, or gaming usernames. These connections create doxxing chains that expose far more than one cleaning contract. Public reporting shows such leaks frequently cascade into account takeovers, especially when the same password was reused across work, personal email, and family gaming platforms. Protecting gaming accounts matters because children’s usernames and shared family emails often become the bridge that lets attackers move from one breach to full identity compromise.

m3rx Group’s Known Track Record

Public reporting attributes the attack to the m3rx ransomware group. The group emerged in recent years and typically gains initial access through common vulnerabilities or phishing, exfiltrates data, then demands payment to prevent publication. Notable prior victims include other small and mid-sized businesses whose internal files were posted on dedicated leak sites when ransom was not paid. Their playbook follows the standard ransomware pattern: steal data, threaten to release it, and use the leak site as leverage. Exact victim counts and earlier incidents remain limited in open sources, but the group’s activity aligns with the broader rise in ransomware operations targeting companies that handle everyday consumer information.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
• Rotate any password you used when dealing with Alge-Stop or similar local providers, and enable 2FA through an authenticator app on every account where that password was reused.
• Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and 100+ platforms so the next leak exposing you or your family is caught in hours rather than months.
• Cover the entire household with DoxxScan family protection, which includes dependents and your children’s gaming accounts that can chain back to the same address or email.
• Let DoxxScan remediation specialists manage takedown requests across data brokers and exposed records on your behalf.
