Sonda (Duplicate with update) Listed by medusa Ransomware Group

On May 5, 2023, Chilean multinational IT services provider Sonda appeared on the leak site of the Medusa ransomware group. The listing states that Medusa first compromised Sonda’s network the previous month, returned on May 4, 2023, and published more than 4 TB of internal files on a public Telegram channel. Anyone with the link can download the data, and the group explicitly warns other companies against using Sonda’s IT support services.

Reported Details from the Listing

The Medusa leak-site entry, mirrored on ransomware.live, declares that Sonda’s network remained vulnerable after the initial breach. It claims a second intrusion occurred on May 4, 2023, after which the attackers exfiltrated and began distributing internal company files. The disclosure does not specify the exact number of records affected or list particular data types beyond “internal files.” A proof image is included on the site, and the group states that more than 4 TB of material is now openly accessible via Telegram. The listing ends with a direct recommendation that other organizations avoid Sonda’s managed IT services.

Why This Matters for You and Your Family

When an IT services company like Sonda suffers a breach, the exposure often reaches far beyond corporate walls. Clients, partners, and ordinary customers whose data passes through Sonda’s systems can find their personal information suddenly public. Even if you have never heard of Sonda, your bank, utility provider, school, or employer may rely on its services. That means your emails, contracts, invoices, or employee records could be among the files now circulating. For families this translates into heightened risk of identity theft, loan fraud, and targeted scams that exploit real names, addresses, and financial relationships pulled from seemingly internal documents.

Doxxing and Identity-Chain Risks

Internal files from an IT provider frequently contain spreadsheets that link employee names to personal emails, phone numbers, project codes, and client lists. Attackers and opportunistic criminals can combine these fragments with data from previous breaches to build complete identity chains. A single leaked work email can lead to your personal accounts, while an exposed client contract can reveal family-member names and home addresses. These chains accelerate doxxing campaigns, SIM-swapping attempts, and account takeovers. Credential leaks of this nature also cascade into gaming platforms; children’s usernames or parent-linked emails reused across services become entry points for harassment or further extortion.

Medusa’s Publicly Known Track Record

Public reporting attributes Medusa’s emergence to mid-2021. The group has since targeted organizations across North America, Europe, and Latin America, with notable prior victims in healthcare, manufacturing, and technology sectors. Their typical playbook begins with initial access gained through compromised credentials or vulnerable remote-desktop services, followed by extensive internal reconnaissance, data exfiltration, and deployment of ransomware. When payment is not received, Medusa publishes samples and full datasets on their leak site and supplementary Telegram channels, applying sustained pressure through public shaming and direct warnings to the victim’s customers. The Sonda listing follows this exact pattern, including the secondary compromise claim and open distribution of files.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can.
• Rotate any password you used at Sonda or any of its clients anywhere it is reused, and switch on 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
• Let remediation specialists handle takedown requests for any exposed personal documents or broker listings that surface from this incident.

The Sonda breach shows how quickly an IT services compromise can place ordinary families in the crosshairs.
