Tor Network C2 Network Evasion
Tor is a free and open-source network that enables anonymous communication. It uses a network of volunteer-operated servers, known as "relays," to route internet traffic in a way that conceals the user's location and usage from surveillance and traffic analysis. By routing traffic through multiple relays, Tor makes it difficult to trace internet activity back to the user.

Peer to peer C2 Network Evasion
Peer-to-peer (P2P) botnets are a type of botnet that uses a decentralized network structure, without a central command and control (C&C) server. Each infected machine in a P2P botnet maintains a list of other trusted computers (including other infected machines), as well as information drop locations and locations where the malware can be updated. Some P2P botnets also use encryption …
C2 via Social Networks Network Evasion
Malware often relies on a communication channel with its operator in order to receive instructions and updates. This channel is known as a command and control (C&C or C2) channel. C&C channels can take various forms, such as internet relay chat (IRC), peer-to-peer protocols, and even social media. The use of C&C channels allows the operator to remotely control the …
C2 via FTP(S) Network Evasion
C2 via FTP is a technique that utilizes the File Transfer Protocol (FTP) to establish command and control communication between an attacker and victim systems. It involves sending commands and receiving responses within FTP sessions, effectively using FTP as a conduit for covert communication.
To implement C2 via FTP, an attacker needs control over an FTP server, and must …
Impair Defenses: Disable or Modify System Firewall Defense Evasion [Mitre]
Adversaries may disable or modify system firewalls in order to bypass controls limiting network usage. Changes could be disabling the entire mechanism as well as adding, deleting, or modifying particular rules. This can be done numerous ways depending on the operating system, including via command-line, editing Windows Registry keys, and Windows Control Panel.
Modifying or disabling a system firewall …
Base64 Data Obfuscation
Base64 is a simple encoding scheme that is often used by malware to represent binary data in an ASCII string. This allows the malware to encode and transmit binary data, such as a payload or network traffic, in a way that is more compact and easier to transmit over text-based communication channels.
Base64 uses a 64-character alphabet to encode …
Caesar Cipher Data Obfuscation
The Caesar Cipher is a simple encoding algorithm that was used during the Roman Empire to hide secret messages. In this algorithm, each letter of the plaintext is replaced with a letter that is a fixed number of positions down the alphabet. For example, if the shift value is 3, then the letter "A" would be replaced with "D", "B" …
Hide Artifacts: Email Hiding Rules Defense Evasion [Mitre]
Adversaries may use email rules to hide inbound emails in a compromised user's mailbox. Many email clients allow users to create inbox rules for various email functions, including moving emails to other folders, marking emails as read, or deleting emails. Rules may be created or modified within email clients or through external features such as the New-InboxRule or Set-InboxRule PowerShell …
Obfuscated Files or Information: Steganography Defense Evasion [Mitre]
Adversaries may use steganography techniques in order to prevent the detection of hidden information. Steganographic techniques can be used to hide data in digital media such as images, audio tracks, video clips, or text files.
Duqu was an early example of malware that used steganography. It encrypted the gathered information from a victim's system and hid it within an …
Obfuscated Files or Information: Embedded Payloads Defense Evasion [Mitre]
Adversaries may embed payloads within other files to conceal malicious content from defenses. Otherwise seemingly benign files (such as scripts and executables) may be abused to carry and obfuscate malicious payloads and content. In some cases, embedded payloads may also enable adversaries to Subvert Trust Controls by not impacting execution controls such as digital signatures and notarization tickets.
