Does this skill support both Windows and Linux?

Yes, it includes comprehensive command sets for PowerShell, certutil, and bitsadmin on Windows, as well as curl, wget, and netcat on Linux environments.

Is encoding supported for file transfers?

Yes, the skill offers methodologies for Base64, Hex, and Gzip encoding to help bypass signature-based detection and facilitate transfers through restricted channels.

Are Living-off-the-land (LOLBAS) techniques included?

Absolutely. It covers native binaries like certutil, mshta, and regsvr32 to perform file operations without the need for downloading third-party tools.

What is the Security File Transfer Techniques skill?

It is a specialized capability for Claude Code that provides expert guidance and command patterns for moving files between systems using both standard and advanced security methodologies.

Can it help with bypassing firewalls?

Yes, the skill provides specific techniques for bypassing egress filtering, including DNS and ICMP exfiltration and leveraging common ports like 53 or 443 for data movement.

安全与测试

Facilitates advanced file transfers and data exfiltration across Linux and Windows using diverse protocols and living-off-the-land techniques.

This skill transforms Claude into a specialized security assistant for file movement and data exfiltration. It provides comprehensive guidance on cross-platform transfers using standard protocols like HTTP, SMB, and FTP, alongside advanced methods like DNS/ICMP exfiltration and Living-Off-The-Land (LOLBAS/GTFOBins) binaries. Designed for security professionals and penetration testers, it assists in tool staging, data exfiltration, and bypassing egress filters while maintaining stealth through encoding, obfuscation, and in-memory execution patterns.
