For the consecutive fourth time, Netfilim ransomware operators publish data leak of MAS Holdings. Earlier to this, they published the data leak part 1, part 2, and part 3 of the company, which were verified and been reported by the Cyble Research Team.

As claimed before by the Cyble Research Team, the Netfilim ransomware operators leaked the fourth part of the company’s data. Based on this data leak it seems that once again the company refused to accept the terms of the ransomware operators. Due to the refusal, the ransomware operators chose to leak the fourth part of the data. Below is the message been posted by Netfilim ransomware operators-:

The Cyble researchers have verified the leak of around 5GB. The data leak includes multiple confidential corporate documents such as the company’s bank reconciliation statements, Debit & Credit notes, Sales forecasts documents, fixed assets record details, and much more.
