CL: Attack on multinational SONDA claimed by Medusa

The Chilean IT multinational SONDA, which has a presence in 11 countries, has been placed on the leaks page of the threat actor Medusa Locker. Medusa’s leak site displays some file captures from different countries where this company operates. The proof includes an affidavit from SONDA Peru, invoices from the parent company, some documents from SONDA Argentina, and identity cards. As Medusa has done with other victims, they produced a video showing what they accessed and acquired.

A countdown clock on the listing shows that SONDA has until April 15 to respond. Medusa lists three prices: $10,000.00 to add another 24 hours to the clock, or $2,000,000.00 to either delete all the data or download all the data.

In a press statement on March 31, SONDA stated that it detected the malware in its systems on March 29. SONDA also stated that client services are segmented from the internal networks and they onboarded Mandiant to help. SONDA’s notice was shared on Twitter by @1ZRR4H. sent email inquiries on April 4 and 5, asking SONDA if Medusa encrypted their files and if they received a ransom note.  They were also asked if the attack affected their operations and if they were negotiating with Medusa at all. No reply was received.

DataBreaches also sent inquiries to Medusa seeking additional details, but they declined to answer the questions, saying only, “Will send the URL of the company in question, now we have too many cases open.”  Medusa did provide what appeared to be a sample on their leak site, but neither the sample nor the list of files could be downloaded when DataBreaches attempted to access them.

ABC reported that from there, he gained access to the Tax Agency information bases in October. Stolen bank details of 575,186 taxpayers were then transferred to two servers hosted in Lithuania.
