Listed above are the best search engines for security professionals and penetration testers, if you use any other search engines add them in the comment section and we will share them with the community.


1. Can Google detect hackers?

Google has advanced systems and technologies to detect and prevent various hacking attempts and security risks.

These systems use powerful algorithms and AI to detect suspicious activity like account hacks, malware distribution, phishing attempts, and vulnerability exploits.

Google’s security infrastructure monitors its services and platforms for malicious activity and takes proactive measures to protect user data and service integrity.

Any security system isn’t perfect, and persistent hackers can sometimes bypass it. Thus, Google advises users to use strong passwords and two-factor authentication to improve security.

2.How do hackers get passwords?

Crackers exploit technical flaws and human psychology to steal passwords. Phishing—impersonating reputable websites or communications—is a prevalent method.

Another approach, keylogging, discreetly records passwords as users type. They also use brute force assaults to guess passwords or social engineering to get people to reveal their credentials.

They also use database security breaches to steal passwords, which can be dangerous if not encrypted. Complex passwords and two-factor authentication are crucial to cybersecurity, as these solutions demonstrate.

3.What is the most common hacked password?

The most commonly compromised password is “123456” according to sources and studies. Users prefer this simple numerical sequence because it’s easy to remember, but it’s also quite hackable.

Other often hacked passwords include “password”, “123456789”, “qwerty”, and “111111”. Simple passwords are popular, but hackers opt for brute force or dictionary assaults because of this.

The frequency of such weak passwords highlights the need for cybersecurity awareness and the need of adopting strong, unique passwords for each account.
