In this digital age, our devices hold a wealth of sensitive information, from financial and personal data to confidential work documents. If you suspect that your email, desktop, or phone has been compromised, it can be a stressful and alarming experience. But don’t panic! There are steps you can take to protect your data and restore your device’s security.

Step 1: Assess the Situation

The first step to take when you suspect your email, desktop, or phone has been compromised is to assess the situation. Here are a few things to look for:

  • Unusual activity: Check for any unusual activity on your device, such as changes to your desktop background or unfamiliar programs running in the background.

  • Unknown files: Look for any unknown files or programs on your device, especially in your Downloads folder or your browser’s download history.

  • Changes to login credentials: If you suspect that your email has been compromised, check your sent folder for any emails you didn’t send and your trash folder for any deleted emails that you didn’t delete. Also, look for changes to your login credentials, such as a new email address or password associated with your account.

  • Unfamiliar emails: If you suspect that your email has been compromised, look for unfamiliar emails in your inbox or spam folder.

  • Unexpected charges: If you suspect that your phone has been compromised, look for any unexpected charges on your phone bill or unusual activity in your call or text message history.

It’s important to take note of any signs of compromise so that you can take appropriate action to protect your device and data. If you are unsure if your device has been compromised, it’s always better to error on the safe side.

Step 2: Change Your Passwords and Verify Recovery Information

If you suspect that your email, desktop, or phone has been compromised, the next step is to change your passwords for all your accounts immediately. This will take a while, so prioritize important accounts like your emails, bank accounts, social media accounts, etc.

  • Prioritize important accounts like your emails, bank accounts, social media accounts, etc.

  • Choose strong, unique passwords for each of your accounts and avoid using the same password across multiple accounts

  • A strong password should be at least 12 characters long and include a mix of upper and lowercase letters, numbers, and symbols

Choose strong, unique passwords for each of your accounts and avoid using the same password across multiple accounts. A strong password should be at least 12 characters long and include a mix of upper and lowercase letters, numbers, and symbols. Avoid using common words or phrases, and don’t include personal information like your name, birthdate, or address.

Some examples of secure passwords:

- G8Q$s#E6jF9h: a 12-character password that includes uppercase and lowercase letters, numbers, and symbols
- Ilovesecurity7!: a 16-character password that includes a combination of words and numbers, and a symbol
- xK2%qpzL5!rS: a 12-character password that includes random uppercase and lowercase letters, numbers, and symbols

Examples of pass phrases:

- sunflower2cherry7socks: a 24-character passphrase that includes three random words with numbers
- orange$5my#yellow: a 16-character passphrase that includes two random words with numbers and symbols
- pizza3onions?lovers: a 19-character passphrase that includes two random words with numbers and a symbol
- tangerine8shark?43: a 18-character passphrase that includes two random words with numbers and a symbol
- elephant6pasta*tree: a 19-character passphrase that includes two random words with numbers and a symbol

It’s also a good idea to enable two-factor authentication, which adds an extra layer of security to your accounts. Two-factor authentication requires a second method of verification, such as a code sent to your phone or email, in addition to your password.

  • Change your passwords from a known clean device or one that has just had its operating system reset or fully reinstalled from scratch

It’s important to change your passwords from a known clean device or one that has just had its operating system reset, or even better, fully reinstalled from scratch. This will ensure that any malware or other compromises on your device won’t be transferred to the new device.

  • Clear all sessions from your account, known or unknown, to kick any attackers out of your account

Also, at this step, most services have dashboards where you can see the active and previous sessions of the account. Go in there and clear all sessions. All of them. Known or unknown. This will kick any attackers out of your account.

  • Verify the account recovery information on the account, including security questions, phone number, or alternate email address
  • Remove any unfamiliar information and replace it with your own information to prevent attackers from using your account recovery information to gain access to your account in the future

Lastly, after changing the password and kicking out other sessions, you should take the time to verify the account recovery information on the account. This may include your security questions, phone number, or alternate email address. If you find any unfamiliar information, remove it and replace it with your own information. This will help prevent attackers from using your account recovery information to gain access to your account in the future.

Step 3: Update Your Software

Keeping your operating system, antivirus, and other software up to date is essential for maintaining the security of your device. Software updates often include security patches that address known vulnerabilities, so it’s important to update your software as soon as possible when updates become available.

To update your software, go to your device’s settings or control panel and check for updates. If updates are available, download and install them as soon as possible.

Examples of software that you should keep up to date include:

  • Operating system (Windows, MacOS, iOS, Android, etc.)
  • Antivirus software (Norton, McAfee, Avast, etc.)
  • Web browser (Google Chrome, Mozilla Firefox, Safari, etc.)
  • Email client (Microsoft Outlook, Apple Mail, Gmail, etc.)
  • Applications (Microsoft Office, Adobe Creative Suite, etc.)

Step 4: Scan Your Device for Malware

  • Run a malware scan on your device to check for any malicious software that may have been installed
  • Malware can include viruses, worms, Trojans, and other types of malicious software that can compromise the security of your device and data
