t00ls大佬分享的技巧1、定位有多少IP在爆破主机的root帐号:
grep "Failed password for root" /var/log/secure | awk ‘{print $11}‘ | sort | uniq -c | sort -nr | more
定位有哪些IP在爆破:
grep "Failed password" /var/log/secure|grep -E -o "(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)"|uniq -c
爆破用户名字典是什么?
grep "Failed password" /var/log/secure|perl -e ‘while($_=<>){ /for(.*?) from/; print "$1\n";}‘|uniq -c|sort -nr
2、登录成功的IP有哪些:
grep "Accepted " /var/log/secure | awk ‘{print $11}‘ | sort | uniq -c | sort -nr | more
登录成功的日期、用户名、IP:
grep "Accepted " /var/log/secure | awk ‘{print $1,$2,$3,$9,$11}‘
