Querying the I/O Communication Port Sandbox Evasion

VMware uses virtual I/O ports for communication between the virtual machine and the host operating system to support functionality like copy and paste between the two systems. The port can be queried and compared with a magic number VMXh to identify the use of VMware.

Checking Pipe Sandbox Evasion

Cuckoo is a malware analysis system that uses a named pipe, called \.\pipe\cuckoo, for communication between the host system (where the malware is being analyzed) and the guest system (where the malware is running).

A malware that is running on the guest system can detect the presence of a virtual environment by attempting to access the \.\pipe\cuckoo named pipe. …

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 …

Cryptography Data Obfuscation

Cryptography is a technique often used by malware to protect against analysis or to perform malicious actions such as in ransomware attacks. In these cases, malware will use cryptography to encrypt their payloads or communication channels in order to make it difficult for security tools and forensic investigators to detect and analyze their activities.

Additionally, cryptography can be used …

Domain Generation Algorithm Network Evasion

Domain generation algorithms (DGAs) are algorithms used by malware to generate a large number of domain names that can be used as communication channels with their command and control servers. These domain names are generated periodically, typically using a pseudorandom number generator.

The use of DGAs makes it difficult for law enforcement and other security actors to shut down …

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.

Malware …

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 …

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 …

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.

Adversaries …

Constant Blinding Data Obfuscation

Constant blinding can be employed by malware authors to obfuscate their malicious code, making it harder for security researchers and antivirus software to detect and analyze the malware. By using constant blinding techniques, the malware code can be concealed, increasing its chances of evading detection and maintaining persistence on the target system.

Here's how constant blinding can be utilized …
