pattern =
r'^(?=.*[A-Z])(?=.*[a-z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$'
return re.match(pattern, password)
print(is_strong_password("Secure@123")) # Output: True

FAQs
❓1. What is the most dangerous cyber threat in 2025?
Answer:
Ransomware continues to be one of the most dangerous threats in 2025 due
to its high success rate and devastating financial impact. Attackers are now
using double extortion—demanding payment to unlock data and to not leak it
publicly.
❓2. How can I tell if a phishing email is fake?
Answer:
Look for red flags like:
- Generic
greetings (e.g., “Dear user”)
- Urgent
or threatening language
- Misspelled
domain names
- Unexpected
attachments or links
- Requests
for sensitive information
Always verify the sender before clicking.
❓3. What should I do if my device is infected with ransomware?
Answer:
- Disconnect
it from the network immediately
- Do
not pay the ransom
- Report
the incident to authorities
- Restore
from a clean backup if available
- Use
professional incident response tools or teams to recover
❓4. Are small businesses really at risk for cyberattacks?
Answer:
Yes—small and medium-sized businesses (SMBs) are increasingly targeted
because they often lack dedicated IT security teams and may be more vulnerable
to phishing, ransomware, or BEC scams.
❓5. What is multi-factor authentication (MFA), and why is it important?
Answer:
MFA adds a second layer of verification beyond a password (e.g., SMS code or
fingerprint). It greatly reduces the risk of unauthorized access—even if your
password is compromised.
❓6. How do zero-day attacks work?
Answer:
Zero-day attacks exploit software vulnerabilities that are not yet known to the
vendor or the public. Since no patch exists, attackers can gain access or
control before security updates are released.
❓7. How do I protect my smart home devices from being hacked?
Answer:
- Change
default login credentials
- Keep
firmware updated
- Place
IoT devices on a separate guest network
- Disable
features you don’t use (e.g., remote access)
❓8. What is credential stuffing, and how is it different from brute-force attacks?
Answer:
Credential stuffing uses previously leaked username/password combinations
to log into accounts. It’s more targeted than brute-force, which tries random
combinations. Prevent it with unique passwords and MFA.
❓9. Can AI be used by hackers too?
Answer:
Yes—cybercriminals now use AI for:
- Creating
convincing phishing content
- Bypassing
spam filters
- Automating
attacks
- Generating
deepfakes
This is why AI-powered defensive tools are also critical.
❓10. What’s the best all-around defense against most cyber threats?
Answer:
A layered security strategy is best, combining:
- User
education
- Firewalls
and antivirus software
- Regular
updates and patching
- MFA
- Strong
password policies
- Regular
backups
Security isn’t just a tool—it’s a process.
