Top 1 – AgentTesla

AgentTesla is an infostealer that has taken first place once again with 32.8%. It is an info-stealer that leaks user credentials saved in web browsers, emails, and FTP clients.

It uses e-mail to leak collected information, and there are samples that used FTP or Discord API. C&C information of recently collected samples is as follows.

  • server :[.]mx (174.136.37[.]109)
    sender : [email protected][.]mx
    receiver : [email protected][.]mx
    user : [email protected][.]mx

    sender : whford@focuzauto[.]com
    receiver : obtxxxtf@gmail[.]com
    user : whford@focuzauto[.]com
