I've been running Wireshark to monitor OpenWrt router's chatter on the WAN side and noticed that as part of DHCP discover OpenWrt sends "udhcp 1.25.1" as part of Vendor Class Identifier. This is known behavior and documented in https://openwrt.org/docs/techref/busybox. Question is how can I remove/obfuscate this info (as it makes identifying router OS/Services and discovering potential vulnerabilities that much easier for an adversary)?
uci set network.wan.vendorid='fishandchips' uci commit network
Useful pointer. Thanks!
