Classe: Trojan-Ransom
Esse tipo de cavalo de Tróia modifica os dados no computador da vítima para que a vítima não possa mais usar os dados ou impede que o computador seja executado corretamente. Depois que os dados forem "tomados como reféns" (bloqueados ou criptografados), o usuário receberá uma demanda de resgate. A demanda de resgate diz à vítima para enviar o dinheiro do usuário malicioso; Após recebê-lo, o criminoso virtual enviará um programa à vítima para restaurar os dados ou restaurar o desempenho do computador.Plataforma: Win32
O Win32 é uma API em sistemas operacionais baseados no Windows NT (Windows XP, Windows 7, etc.) que oferece suporte à execução de aplicativos de 32 bits. Uma das plataformas de programação mais difundidas do mundo.Família: Trojan-Ransom.Win32.DoppelPaymer

TA0002
Execution
The adversary is trying to run malicious code. Execution consists of techniques that result in adversary-controlled code running on a local or remote system. Techniques that run malicious code are often paired with techniques from all other tactics to achieve broader goals, like exploring a network or stealing data. For example, an adversary might use a remote access tool to run a PowerShell script that does Remote System Discovery.
T1203
Exploitation for Client Execution
Adversaries may exploit software vulnerabilities in client applications to execute code. Vulnerabilities can exist in software due to unsecure coding practices that can lead to unanticipated behavior. Adversaries can take advantage of certain vulnerabilities through targeted exploitation for the purpose of arbitrary code execution. Oftentimes the most valuable exploits to an offensive toolkit are those that can be used to obtain code execution on a remote system because they can be used to gain access to that system. Users will expect to see files related to the applications they commonly used to do work, so they are a useful target for exploit research and development because of their high utility.
TA0005
Stealth
The adversary is trying to hide and conceal their actions, appearing as normal behavior. Stealth consists of techniques that reduce the likelihood of detection by blending in with legitimate activity or minimizing observable signals. These techniques are characterized by concealment behaviors, such as avoiding, obfuscating, or mimicking normal operations, without modifying security controls or compromising collection and monitoring feeds. The goal is to remain indistinguishable from benign activity while leaving defensive systems intact.
T1036.008
Masquerade File Type
Adversaries may masquerade malicious payloads as legitimate files through changes to the payload's formatting, including the file’s signature, extension, icon, and contents. Various file types have a typical standard format, including how they are encoded and organized. For example, a file’s signature (also known as header or magic bytes) is the beginning bytes of a file and is often used to identify the file’s type. For example, the header of a JPEG file, is
0xFF 0xD8 and the file extension is either `.JPE`, `.JPEG` or `.JPG`. * © 2026 The MITRE Corporation. This work is reproduced and distributed with the permission of The MITRE Corporation.
