Sekhmet ransom note

Type and source of infection

Ransom.Maze is ransomware. Ransomware in general makes files on the victims system unusable until the ransom is payed. Ransom.Sekhmet not only encrypts a victims files, but also threatens to publish them.
Egregor uses an affiliate program, the so-called Ransomware-as-a-Service (RaaS) model which means that each criminal who uses it can decide how to infect the intended victims.

Aftermath

According to the ransom note, if the ransom is not paid by the company within 3 days then, aside from leaking part of the stolen data, the operators will publish in the media about the breach so the company’s partners and clients will know that the company was succesfully attacked.
