Is data transfer using vrangesync's 'ncat' remote transport safe?
Regular unix/linux old-timer will know that 'netcat' often use by hacker for malicious activity.
Do not confuse 'ncat' with 'netcat'. ncat(developed by nmap) is different from traditional 'netcat' found on the market.
ncat(developed by nmap) is an 'improved' version of netcat with more security features.
1)Vrangesync activate 'ncat's file-transfer' feature to do the send/receive data transfer. It will only save the data to the specific file location on the storage device. No scripting allow. No code execution allow.
2)Vrangesync also offer 'auto-select port from a range-port' feature to enhance security. It will pick one of the ports from a range of ports(For example, 5000-12222) It will deter any network sniffer from knowing which port you are send/receive data in between the machines.
3)Vrangesync also use data compression algorithm to scamble the data during the transfer.
4)Vrangesync's 'ncat' binary have the fingerprint(checksum) check. Vrangesync will not run if the 'ncat' binary provided within the toolpack had been tempted with.
It is safe to use vrangesync's 'ncat' for remote transport with the above security measures.
