Kaspersky Threats — P2P-Worm.Win32.Palevo.hyka

Classe: P2P-Worm

Os worms P2P se espalham através de redes de compartilhamento de arquivos peer-to-peer (como Kazaa, Grokster, EDonkey, FastTrack, Gnutella, etc.). A maioria desses worms funciona de uma maneira relativamente simples: para entrar em uma rede P2P, tudo o que o worm precisa fazer é copiar-se para o diretório de compartilhamento de arquivos, que geralmente está em uma máquina local. A rede P2P faz o resto: quando uma pesquisa de arquivo é realizada, ela informa os usuários remotos do arquivo e fornece serviços que permitem baixar o arquivo do computador infectado. Há também P2P-Worms mais complexos que imitam o protocolo de rede de um sistema específico de compartilhamento de arquivos e respondem positivamente às consultas de pesquisa; uma cópia do P2P-Worm é oferecida como uma correspondência.

Plataforma: Win32

O Win32 é uma API em sistemas operacionais baseados no Windows NT (Windows XP, Windows 7, etc.) que oferece suporte à execução de aplicativos de 32 bits. Uma das plataformas de programação mais difundidas do mundo.

Tactics and Techniques: Mitre*

TA0005

Defense Evasion

The adversary is trying to avoid being detected. Defense Evasion consists of techniques that adversaries use to avoid detection throughout their compromise. Techniques used for defense evasion include uninstalling/disabling security software or obfuscating/encrypting data and scripts. Adversaries also leverage and abuse trusted processes to hide and masquerade their malware. Other tactics' techniques are cross-listed here when those techniques include the added benefit of subverting defenses.

T1497.003

Time Based Evasion

Adversaries may employ various time-based methods to detect and avoid virtualization and analysis environments. This may include enumerating time-based properties, such as uptime or the system clock, as well as the use of timers or other triggers to avoid a virtual machine environment (VME) or sandbox, specifically those that are automated or only operate for a limited amount of time.

TA0006

Credential Access

The adversary is trying to steal account names and passwords. Credential Access consists of techniques for stealing credentials like account names and passwords. Techniques used to get credentials include keylogging or credential dumping. Using legitimate credentials can give adversaries access to systems, make them harder to detect, and provide the opportunity to create more accounts to help achieve their goals.

T1552.008

Chat Messages

Adversaries may directly collect unsecured credentials stored or passed through user communication services. Credentials may be sent and stored in user chat communication applications such as email, chat services like Slack or Teams, collaboration tools like Jira or Trello, and any other services that support user communication. Users may share various forms of credentials (such as usernames and passwords, API keys, or authentication tokens) on private or public corporate internal communications channels.

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.
