Kaspersky Threats — Exploit.Win32.ChecksumController.ajc

Classe: Exploit

Exploits sont des programmes qui contiennent des données ou un code exécutable qui tirent parti d'une ou de plusieurs vulnérabilités dans un logiciel exécuté sur un ordinateur local ou distant à des fins clairement malveillantes. Souvent, les utilisateurs malveillants utilisent un exploit pour pénétrer un ordinateur victime afin d'installer ensuite du code malveillant (par exemple, pour infecter tous les visiteurs d'un site Web compromis avec un programme malveillant). En outre, les exploits sont couramment utilisés par Net-Worms afin de pirater un ordinateur victime sans qu'aucune action ne soit requise de la part de l'utilisateur. Les programmes de Nuker sont notables parmi les exploits; ces programmes envoient des requêtes spécialement conçues à des ordinateurs locaux ou distants, entraînant le blocage du système.

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.

T1059.001

PowerShell

Adversaries may abuse PowerShell commands and scripts for execution. PowerShell is a powerful interactive command-line interface and scripting environment included in the Windows operating system. Adversaries can use PowerShell to perform a number of actions, including discovery of information and execution of code. Examples include the Start-Process cmdlet which can be used to run an executable and the Invoke-Command cmdlet which runs a command locally or on a remote computer (though administrator permissions are required to use PowerShell to connect to remote systems).

TA0005

Stealth

The adversary is trying to hide and conceal their actions, appearing as normal behavior. Stealth consists of techniques that reduce the likelihood of detection by blending in with legitimate activity or minimizing observable signals. These techniques are characterized by concealment behaviors, such as avoiding, obfuscating, or mimicking normal operations, without modifying security controls or compromising collection and monitoring feeds. The goal is to remain indistinguishable from benign activity while leaving defensive systems intact.

T1036.003

Rename Legitimate Utilities

Adversaries may rename legitimate / system utilities to try to evade security mechanisms concerning the usage of those utilities. Security monitoring and control mechanisms may be in place for legitimate utilities adversaries are capable of abusing, including both built-in binaries and tools such as PSExec, AutoHotKey, and IronPython. It may be possible to bypass those security mechanisms by renaming the utility prior to utilization (ex: rename rundll32.exe). An alternative case occurs when a legitimate utility is copied or moved to a different directory and renamed to avoid detections based on these utilities executing from non-standard paths.

T1070.006

Timestomp

Adversaries may modify file time attributes to hide new files 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 and blend malicious files with legitimate files.

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.

T1012

Query Registry

Adversaries may interact with the Windows Registry to gather information about the system, configuration, and installed software.

T1082

System Information Discovery

An adversary may attempt to get detailed information about the operating system and hardware, including version, patches, hotfixes, service packs, and architecture. Adversaries may use this information to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions. This behavior is distinct from Local Storage Discovery which is an adversary's discovery of local drive, disks and/or volumes.

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.
