Using Malware to Capture Passwords
Hackers may use malware to capture passwords and then use that information to change the password. For example, a hacker may use a keylogger to capture a user’s password and then use that password to log in to the account and change the password.
Utilizing Password Spraying Attacks
Password spraying attacks involve using a list of commonly used passwords to try and guess a password. If a hacker is able to guess a password, they may use that password to log in to the account and change the password.
Leveraging Social Engineering Tactics
Hackers may use social engineering tactics to trick users into revealing their passwords or other sensitive information. For example, a hacker may call a user and claim to be from a bank or other organization, asking the user to reveal their password or other sensitive information.
Risks Associated with Password Changes
When a hacker changes a password, it can have serious consequences, including:
Unauthorized Access to Sensitive Information
If a hacker changes a password, they may gain unauthorized access to sensitive information, such as financial data, personal identifiable information, or confidential business data.
Financial Loss
A hacker may use a changed password to gain access to a user’s financial accounts, leading to financial loss.
Reputation Damage
If a hacker changes a password and uses the account to send spam or malicious emails, it can damage the user’s reputation.
Loss of Productivity
If a hacker changes a password, it can cause a user to lose access to their account, leading to a loss of productivity.
Protecting Your Accounts from Password Changes
To protect your accounts from password changes, follow these best practices:
Use Strong, Unique Passwords
Use strong, unique passwords for each of your accounts. Avoid using easily guessable information, such as your name, birthdate, or common words.

What are the common techniques used by hackers to change passwords?
Hackers use various techniques to change passwords, including phishing, password cracking, and social engineering. Phishing involves tricking victims into revealing their login credentials through fake emails, websites, or messages. Password cracking, on the other hand, involves using specialized software to guess or crack passwords. Social engineering involves manipulating individuals into divulging sensitive information, such as passwords, by exploiting human psychology.
Other techniques used by hackers include keylogging, which involves installing malware on a victim’s device to capture keystrokes, and session hijacking, which involves intercepting and taking control of a user’s session. Hackers may also use password spraying, which involves trying a list of commonly used passwords against multiple accounts. Additionally, they may exploit vulnerabilities in password reset processes or use malware to steal password hashes.
How do hackers use phishing to change passwords?
Hackers use phishing to trick victims into revealing their login credentials by creating fake emails, websites, or messages that appear legitimate. These fake communications often contain links or attachments that, when clicked or opened, install malware or redirect the victim to a fake login page. The hacker can then capture the victim’s login credentials and use them to change the password.
Phishing attacks can be highly sophisticated, making it difficult for victims to distinguish between legitimate and fake communications. Hackers may use spoofed email addresses, logos, and branding to create a sense of authenticity. They may also use urgent or threatening language to create a sense of panic, prompting the victim to act quickly without verifying the authenticity of the communication.
What is password cracking, and how do hackers use it to change passwords?
Password cracking involves using specialized software to guess or crack passwords. Hackers use password cracking tools, such as John the Ripper or Aircrack-ng, to try a large number of password combinations against a target account. These tools can try millions of combinations per second, making it possible to crack weak passwords quickly.
Password cracking can be performed online or offline. Online password cracking involves trying password combinations against a live account, while offline password cracking involves cracking password hashes obtained through other means, such as data breaches or malware. Hackers may also use rainbow tables, which are precomputed tables of password hashes, to crack passwords more efficiently.
How can I protect my accounts from password hacking?
To protect your accounts from password hacking, use strong and unique passwords for each account. Avoid using easily guessable information, such as your name, birthdate, or common words. Instead, use a combination of uppercase and lowercase letters, numbers, and special characters. Consider using a password manager to generate and store complex passwords.
Enable two-factor authentication (2FA) whenever possible, which requires both a password and a second form of verification, such as a code sent to your phone or a biometric scan. Keep your software and operating system up to date, and use antivirus software to protect against malware. Be cautious when clicking on links or opening attachments from unknown sources, and avoid using public computers or public Wi-Fi to access sensitive accounts.
What is social engineering, and how do hackers use it to change passwords?
Social engineering involves manipulating individuals into divulging sensitive information, such as passwords, by exploiting human psychology. Hackers use social engineering tactics, such as pretexting, baiting, or quid pro quo, to trick victims into revealing their login credentials. Pretexting involves creating a fake scenario to gain the victim’s trust, while baiting involves offering something in exchange for sensitive information.
Quid pro quo involves offering a service or benefit in exchange for sensitive information. Hackers may also use social engineering to trick victims into installing malware or revealing sensitive information through phone or email scams. Social engineering attacks can be highly effective, as they exploit human weaknesses rather than technical vulnerabilities.
