Třída: Trojan-Dropper
Programy Trojan-Dropper jsou navrženy tak, aby tajně nainstalovaly škodlivé programy zabudované do svého kódu do počítačů poškozených.Tento typ škodlivého programu obvykle ukládá řadu souborů do jednotky oběti (obvykle do adresáře systému Windows, adresáře systému Windows, dočasného adresáře atd.) A spouští je bez jakéhokoli oznámení (nebo s falešným upozorněním na chybu archivu, zastaralá verze operačního systému atd.).
Takové programy používají hackeři k:
tajně nainstalujte programy trojských koní a / nebo viry
chránit známé škodlivé programy od antivirových řešení; ne všechny antivirové programy dokáží skenovat všechny součásti tohoto typu trojských koní.
Platfoma: Win32
Win32 je rozhraní API v operačních systémech Windows NT (Windows XP, Windows 7 atd.), Které podporují provádění 32bitových aplikací. Jedna z nejrozšířenějších programovacích platforem na světě.Family: Trojan-Dropper.Win32.Agent

Tactics and Techniques: Mitre*

Defense Evasion
The adversary is trying to avoid being detected.
Defense Evasion consists of techniques that adversaries use to avoid detection throughout their compromise. Techniques used for defense evasion include uninstalling/disabling security software or obfuscating/encrypting data and scripts. Adversaries also leverage and abuse trusted processes to hide and masquerade their malware. Other tactics’ techniques are cross-listed here when those techniques include the added benefit of subverting defenses.

Masquerading: Right-to-Left Override
Adversaries may abuse the right-to-left override (RTLO or RLO) character (U+202E) to disguise a string and/or file name to make it appear benign. RTLO is a non-printing Unicode character that causes the text that follows it to be displayed in reverse. For example, a Windows screensaver executable named
Adversaries may abuse the RTLO character as a means of tricking a user into executing what they think is a benign file type. A common use of this technique is with Spearphishing Attachment/Malicious File since it can trick both end users and defenders if they are not aware of how their tools display and render the RTLO character. Use of the RTLO character has been seen in many targeted intrusion attempts and criminal activity.(Citation: Trend Micro PLEAD RTLO)(Citation: Kaspersky RTLO Cyber Crime) RTLO can be used in the Windows Registry as well, where regedit.exe displays the reversed characters but the command line tool reg.exe does not by default.
