Sınıf: Trojan-Dropper
Trojan-Dropper programları, kurban bilgisayarlarına kodlarının içerdiği kötü amaçlı programları gizlice yüklemek için tasarlanmıştır. Bu tip kötü amaçlı program genellikle bir dizi dosyayı kurbanın sürücüsüne (genellikle Windows dizinine, Windows sistem dizinine, geçici dizine vb.) Kaydeder ve bunları herhangi bir bildirimde bulunmadan başlatır (veya bir arşiv hatasıyla ilgili sahte bildirim ile) eski işletim sistemi sürümü, vb. Bu tür programlar hackerlar tarafından kullanılır: Trojan programlarını ve / veya virüsleri gizlice yüklemek, bilinen kötü amaçlı programları antivirüs çözümleri tarafından algılanmaktan korur; Tüm antivirüs programları bu tip Truva atlarının içindeki tüm bileşenleri tarayamaz.Platform: Win32
Win32, 32-bit uygulamaların yürütülmesini destekleyen Windows NT tabanlı işletim sistemlerinde (Windows XP, Windows 7, vb.) Bir API'dir. Dünyanın en yaygın programlama platformlarından biri.Aile: Trojan-Dropper.Win32.NSIS

Tactics and Techniques: Mitre*
TA0005
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.

Indicator Removal: Timestomp
Adversaries may modify file time attributes to hide new or changes to existing files. Timestomping is a technique that modifies the timestamps of a file (the modify, access, create, and change times), often to mimic files that are in the same folder. This is done, for example, on files that have been modified or created by the adversary so that they do not appear conspicuous to forensic investigators or file analysis tools.
Timestomping may be used along with file name Masquerading to hide malware and tools.(Citation: WindowsIR Anti-Forensic Techniques)

TA0009
Collection
The adversary is trying to gather data of interest to their goal.
Collection consists of techniques adversaries may use to gather information and the sources information is collected from that are relevant to following through on the adversary's objectives. Frequently, the next goal after collecting data is to steal (exfiltrate) the data. Common target sources include various drive types, browsers, audio, video, and email. Common collection methods include capturing screenshots and keyboard input.

T1560.001
Archive Collected Data: Archive via Utility
Adversaries may use utilities to compress and/or encrypt collected data prior to exfiltration. Many utilities include functionalities to compress, encrypt, or otherwise package data into a format that is easier/more secure to transport.
Adversaries may abuse various utilities to compress or encrypt data before exfiltration. Some third party utilities may be preinstalled, such as
On Windows,
Adversaries may use also third party utilities, such as 7-Zip, WinRAR, and WinZip, to perform similar activities.(Citation: 7zip Homepage)(Citation: WinRAR Homepage)(Citation: WinZip Homepage)
Adversaries may abuse various utilities to compress or encrypt data before exfiltration. Some third party utilities may be preinstalled, such as
tar on Linux and macOS or zip on Windows systems. On Windows,
diantz or makecab may be used to package collected files into a cabinet (.cab) file. diantz may also be used to download and compress files from remote locations (i.e. Remote Data Staging).(Citation: diantz.exe_lolbas) xcopy on Windows can copy files and directories with a variety of options. Additionally, adversaries may use certutil to Base64 encode collected data before exfiltration. Adversaries may use also third party utilities, such as 7-Zip, WinRAR, and WinZip, to perform similar activities.(Citation: 7zip Homepage)(Citation: WinRAR Homepage)(Citation: WinZip Homepage)
