Chashell is a Go-based reverse shell that tunnels communication over DNS, paired with a multi-client control server called chaserv. All traffic is encrypted with XSalsa20 + Poly1305 and serialized with Protocol Buffers, allowing command execution across firewalls and tightly restricted networks.

Use cases

• establish a reverse shell over DNS to bypass firewalls
• control multiple compromised hosts from a single server
• exfiltrate shell access from networks that only allow DNS traffic
• run commands on a target behind a tightly restricted network
• red team post-exploitation command and control
• test network egress filtering controls

When to choose

• you need command-and-control across a network where only DNS is permitted
• you want a lightweight, cross-platform Go reverse shell with encrypted channels
• you need multi-session management from a single operator console

When to avoid

• you need a full-featured C2 framework with file transfer and persistence
• you require asymmetric encryption or modern protocol support
• you need actively maintained software with a license and recent updates
• DNS tunneling is blocked or monitored on the target network
