# EDUCATIONAL EXAMPLE - Defensive testing only
import imaplib
def check_mail_access(host, email, password):
try:
mail = imaplib.IMAP4_SSL(host)
mail.login(email, password)
print(f"[VALID] email:password")
return True
except Exception as e:
print(f"[INVALID] email:password - e")
return False Often, these ZIPs contain configuration files (
Since you now know the mechanics, here are five concrete defenses:
A "checker" can only test passwords. MFA stops 99.9% of automated login attacks dead.
