from collections import Counter
logfile = "~/Desktop/Investigations/webserver-auth-logs.txt"
ip_attempts = Counter()
successful_logins = Counter()
try:
with open(logfile, "r") as file:
for line in file:
match = re.search(r"from (\d+\.\d+\.\d+\.\d+)", line)
if match:
ip = match.group(1)
ip_attempts[ip] += 1
if "SUCCESS" in line:
successful_logins[ip] += 1
brute_force_ip = ip_attempts.most_common(1)[0][0]
success_count = successful_logins[brute_force_ip]
print(f"IP Performing Brute Force: {brute_force_ip}")
print(f"Total Successful Authentications: {success_count}")
except Exception as e:
print(f"Error: {str(e)}")
