Kaspersky Threats — Exploit.Win64.Crun.yg

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: Win64

Win64, 32/64-bit uygulamaların yürütülmesi için Windows tabanlı işletim sistemlerinde bir platformdur. Win64 programları, Windows'un 32 bit sürümlerinde başlatılamaz.

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.

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.

T1033

System Owner/User Discovery

Adversaries may attempt to identify the primary user, currently logged in user, set of users that commonly uses a system, or whether a user is actively using the system. They may do this, for example, by retrieving account usernames or by using OS Credential Dumping. The information may be collected in a number of different ways using other Discovery techniques, because user and username details are prevalent throughout a system and include running process ownership, file/directory ownership, session information, and system logs. Adversaries may use the information from System Owner/User Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.

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.

T1123

Audio Capture

An adversary can leverage a computer's peripheral devices (e.g., microphones and webcams) or applications (e.g., voice and video call services) to capture audio recordings for the purpose of listening into sensitive conversations to gather information.
