Kaspersky Threats — Worm.Win32.Vobfus.eswq

Classe: Worm

Les vers se propagent sur les réseaux informatiques via des ressources réseau. Contrairement à Net-Worms, un utilisateur doit lancer un ver afin qu'il soit activé. Ce type de ver recherche les réseaux informatiques distants et se copie dans les répertoires accessibles en lecture / écriture (s'il en trouve). En outre, ces vers utilisent les fonctions intégrées du système d'exploitation pour rechercher des répertoires réseau accessibles et / ou ils recherchent au hasard des ordinateurs sur Internet, s'y connectent et tentent d'accéder pleinement aux disques de ces ordinateurs. Cette catégorie couvre également les vers qui, pour une raison ou une autre, ne rentrent dans aucune des autres catégories définies ci-dessus (par exemple les vers pour les appareils mobiles).

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.

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.

T1115

Clipboard Data

Adversaries may collect data stored in the clipboard from users copying information within or between applications.

For example, on Windows adversaries can access clipboard data by using clip.exe or Get-Clipboard.(Citation: MSDN Clipboard)(Citation: clip_win_server)(Citation: CISA_AA21_200B) Additionally, adversaries may monitor then replace users’ clipboard with their data (e.g., Transmitted Data Manipulation).(Citation: mining_ruby_reversinglabs)

macOS and Linux also have commands, such as pbpaste, to grab clipboard contents.(Citation: Operating with EmPyre)

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.
