Summary

The Negasteal malware appeared in 2017 as a variant of AgentTesla by simply having the string "Negasteal" in the binary. It has the same command and control panel and communication protocol features of Agent Tesla which first appeared in 2015.

The current malspam campaign utilizes social engineering in which the email contains product inquiry or purchase order inquiry sent to marketing officers of different companies. The malicious spam has .iso, .ace or .gz attachments which are archived files that contain the malware. This Trojan-Spyware sends the data it gathers from its victims to the email address of the malware author via Simple Mail Transfer Protocol (SMTP).

This Trojan-Spyware gathers the following data and sends it to its servers:

  • Computer information (OS version, computer name, OS version platform, IP address, user name, physical memory size)
  • Hardware information (processor name, video card name, video card memory)
  • Browser's user names and passwords
  • File Transfer Protocol (FTP) clients or file manager software stored account information
  • Email credentials of popular mail clients
