Kaspersky Threats — Exploit.Win32.Shellcode.cgxe

Sınıf: Exploit

Exploits, açık veya kötü niyetli amaçlarla yerel veya uzak bilgisayarda çalışan yazılımlardaki bir veya daha fazla güvenlik açığından yararlanan veri veya yürütülebilir kod içeren programlardır. Çoğu zaman, kötü niyetli kullanıcılar, daha sonra kötü amaçlı kod yüklemek için (örneğin, tüm ziyaretçileri kötü niyetli bir programla tehlikeye girmiş bir web sitesine bulaştıracak şekilde) bir kurbanın bilgisayarına girmek için bir istismar kullanırlar. Ayrıca, kullanıcılardan herhangi bir işlem yapılmaksızın bir kurbanın bilgisayarını kesmek için, Net-Worms tarafından istismarlar yaygın olarak kullanılmaktadır. Nuker programları istismarlar arasında dikkate değerdir; Bu tür programlar, yerel veya uzak bilgisayarlara özel hazırlanmış istekleri göndererek sistemin çökmesine neden olur.

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.

Tactics and Techniques: Mitre*

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.

T1106

Native API

Adversaries may interact with the native OS application programming interface (API) to execute behaviors. Native APIs provide a controlled means of calling low-level OS services within the kernel, such as those involving hardware/devices, memory, and processes. These native APIs are leveraged by the OS during system boot (when other system components are not yet initialized) as well as carrying out tasks and requests during routine operations.

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.

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.

T1010

Application Window Discovery

Adversaries may attempt to get a listing of open application windows. Window listings could convey information about how the system is used. For example, information about application windows could be used identify potential data to collect as well as identifying security tooling (Security Software Discovery) to evade.

T1518.001

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 cloud monitoring agents 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.
