What is t2hash-core?

T2HASH-CORE is a network tunneling tool written entirely in x64 Assembly, a very low-level programming language that talks directly to the computer's processor without any software layers in between. The README is written in Persian and describes this as a Layer-0 tunneling engine, meaning it operates below the level where most software runs. The core idea is to send and receive network packets by communicating directly with the Linux operating system's kernel, bypassing the standard libraries that programs normally use. By skipping those layers, the project claims to achieve near-zero processing overhead and microsecond latency, even at high packet volumes. Packets are processed directly in CPU registers and transformed using XOR bitwise operations before being sent over the network. A key stated feature is evasion of Deep Packet Inspection (DPI), which is the technology that network monitoring systems and firewalls use to identify the type of traffic passing through them. The tool is designed to make its outgoing traffic look like random UDP noise rather than a recognizable tunneling protocol, so monitoring systems cannot classify it. The README specifically mentions that it avoids the known signatures of other tunneling protocols. Deployment is done via a single command that downloads and runs an installer script on an Ubuntu or Debian server with root access. The binary itself is described as obfuscated and closed-source, meaning the compiled executable is protected against analysis and the source code for the final binary is not publicly available. The project requires root access and interacts directly with Linux kernel settings, including automatically adjusting network buffer sizes. The README recommends running it only on fresh server installations.
