Třída: Trojan-Downloader
Programy klasifikované jako Trojan-Downloader stahovat a instalovat nové verze škodlivých programů, včetně trojských koní a AdWare, na počítače s oběťmi. Po stažení z Internetu jsou programy spuštěny nebo zařazeny do seznamu programů, které se automaticky spustí, když se spustí operační systém.Informace o jménech a umístěních programů, které jsou staženy, jsou v kódu trojského koně, nebo jsou staženy z Trojského webu z internetového zdroje (obvykle webové stránky).
Tento typ škodlivého programu se často používá při počáteční infekci návštěvníků na webové stránky, které obsahují exploity.
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-Downloader.Win32.Genome

Tactics and Techniques: Mitre*
TA0007
Discovery
The adversary is trying to figure out your environment.
Discovery consists of techniques an adversary may use to gain knowledge about the system and internal network. These techniques help adversaries observe the environment and orient themselves before deciding how to act. They also allow adversaries to explore what they can control and what’s around their entry point in order to discover how it could benefit their current objective. Native operating system tools are often used toward this post-compromise information-gathering objective.

Peripheral Device Discovery
Adversaries may attempt to gather information about attached peripheral devices and components connected to a computer system.(Citation: Peripheral Discovery Linux)(Citation: Peripheral Discovery macOS) Peripheral devices could include auxiliary resources that support a variety of functionalities such as keyboards, printers, cameras, smart card readers, or removable storage. The information may be used to enhance their awareness of the system and network environment or may be used for further actions.
T1518.001
Software Discovery: Security Software Discovery
Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on a system or in a cloud environment. This may include things such as firewall rules and anti-virus. Adversaries may use the information from Security Software Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Example commands that can be used to obtain security software information are netsh,
Adversaries may also utilize cloud APIs to discover the configurations of firewall rules within an environment.(Citation: Expel IO Evil in AWS) For example, the permitted IP ranges, ports or user accounts for the inbound/outbound rules of security groups, virtual firewalls established within AWS for EC2 and/or VPC instances, can be revealed by the
Example commands that can be used to obtain security software information are netsh,
reg query with Reg, dir with cmd, and Tasklist, but other indicators of discovery behavior may be more specific to the type of software or security system the adversary is looking for. It is becoming more common to see macOS malware perform checks for LittleSnitch and KnockKnock software.Adversaries may also utilize cloud APIs to discover the configurations of firewall rules within an environment.(Citation: Expel IO Evil in AWS) For example, the permitted IP ranges, ports or user accounts for the inbound/outbound rules of security groups, virtual firewalls established within AWS for EC2 and/or VPC instances, can be revealed by the
