Scramble, Anonymize, Obfuscate, Scrub, Sanitize, Edit Pcap files at any stack layer
SafePCAP is a universal scriptable L2-L7 Pcap anonymizer, sanitizer, and editor. It allows for easy editing of packet capture data at any stack layer while fully preserving the packets integrity. A SafePCAP sanitized Pcap file can be analyzed as easily as the original, but has sensitive data scrambled.
Hundreds of protocol stacks are supported. Full support for all 3G/LTE 3GPP Mobile Core protocols and interfaces including SS7, RANAP, DIAMETER, and VoLTE.
SafePCAP can be executed from a command line. For example, this is the command to replace IP address velues for all packets at all stack layers:
SafePcapCLI.exe input.pcap -find 192.168.104.179 -replacewith 220.127.116.11 -find 192.168.105.49 -replacewith 18.104.22.168 -save output.pcapng
Visually edit a captured packet at any stack layer. Obfuscate any field. Add/Delete an optional field of the packet with a click.
Dependencies in the modified data are recalculated automatically. No worry about offsets, checksums, encoding, etc.
Automation is supported. To repeat a multi-step editing/scrubbing operation, run each step from a CLI in a batch file.
Both tools are made by Omnipacket. WireEdit is free to download/use for any purpose, while SafePCAP is a commercial product. SafePCAP features and capabilities are a superset of WireEdit features and capabilities. The major additional SafePCAP features/capabilities: pcapng format support, native builds for Linux and OSX, large files (> 2 Gig), hundreds of additional protocols, fine-grained replace operations, higher speed of execution, programmability, CLI, faster bug fixing, enterprise level support.
Other tools can't anonymize binary encoded stack layers above UDP/TCP. They take a simplistic approach of zeroing them out. This approach is far from ideal for some of the use cases. For example, it makes an effective analysis of anonymized 3GPP Mobile Core Pcap files impossible.
A popular opinion on the Subj is expressed here. It is indeed difficult to write software which allows editing of all fields at all stack layers without breaking packets integrity. SafePCAP supports it today.
All other packet editing tools are very limited in their ability to edit binary encoded stack layers above TCP/UDP. SafePCAP and WireEdit are the only packet editors supporting this capability by design.
