Suspect you've been hacked? Here's What to Do

Oh no! If you suspect that you’ve been hacked, we understand how unsettling it can be. While PortDroid might not be your first line of defense, we can certainly offer you some advice to help navigate the situation:

Passwords

If you know or suspect someone knows your password(s):

Reset Your Passwords: If you suspect that a friend, family member, ex-partner, or anyone else who may know your passwords could be behind the breach, it’s time to change your passwords. This includes your email, social media, banking, and any other online accounts you have. Also, consider using a password manager (such as bitwarden or lastpass ) to help create and store unique, complex passwords for each of your accounts.

Set Up Two-Factor Authentication: Adding an extra layer of security, like two-factor authentication, can greatly enhance your account security. It requires not only your password but also a second piece of information that only you would have access to.

Check Your Device for Unwanted Applications: In case someone with physical access to your device may have installed unwanted software or apps, take a thorough look at your installed applications and remove anything suspicious or unknown.

Maintain Device Privacy: Ensure your device is locked when not in use, and consider changing the locking method if someone else knows it. This could be your PIN, password, pattern, or biometric method (like a fingerprint or facial recognition).

Tracking Software

If you suspect someone has installed tracking software on your device:

Reach out local law enforcement - If you believe you’re in danger or if a crime may have been committed, don’t hesitate to inform the authorities.

Get Rid of Unknown or Suspicious Apps - Ensure to uninstall these via the settings menu, not just from the device’s home screen, as some apps may be hidden.

Update Your Device - Keeping your OS and apps up-to-date is an essential measure in maintaining your digital security.

Replace your device: For complete peace of mind, replacing or factory resetting your device and starting fresh may be a good idea. Just ensure that your password is not compromised so that any one with access to you account cannot compromise the clean device.

Network Compromise

If you suspect a device on your network has been compromised:

Contact local law enforcement - if you feel you are in danger or want to report a crime.

Scan for known backdoors into your devices - Use PortDroid to scan for backdoors on your devices.

Identify all devices on network - List all the ones you know to be safe and investigate any unknown devices.

Change WiFi Password - Ensure your WiFi password is strong and not shared with untrusted people / devices.

Install network protections - Install an Intrusion Protection System (IPS) or Intrusion Detection System (IDS), this is available as an option on some routers.

Use a more secure DNS server - Using a secure DNS server such as 9.9.9.9 will protect against some malware and phishing attacks.

General Advice

Remember, in any case of a suspected security breach, it’s better to err on the side of caution. If something feels off, it’s always a good idea to take these steps to ensure your digital security.

A proactive approach to your digital security can greatly enhance your overall protection. Regularly review your online account activities; most services provide an audit trail showing where and when your account has been accessed, which can help in spotting any suspicious patterns.

Always be vigilant about potential phishing attempts. Cybercriminals often resort to deceptive tactics, like posing as trusted entities to trick you into revealing your sensitive information.

Lastly, empower yourself through knowledge. Familiarize yourself with common cyber threats such as phishing, spoofing, and other hacking techniques. The more you understand these threats, the better equipped you’ll be to identify and counteract them. Remember, maintaining a robust digital security posture is an ongoing process, not a one-time task.

FAQs

Why cant I see MAC addresses anymore?

As of recent updates to the Android operating system, the ability for apps to access the MAC addresses of devices found on local network scans has been restricted. This change is a part of Google’s broader initiative to improve user privacy and data security, where one of the primary areas of focus has been limiting access to potentially sensitive hardware identifiers such as MAC addresses.

This is great news for our own personal privacy, but bad news for applications like PortDroid. As this means that while we can still perform network scans and provide insights on open ports, host names, and other network characteristics, it is no longer able to display the MAC addresses of detected devices. This change is beyond the control of individual app developers and is a result of alterations in the Android system’s fundamental accessibility permissions. As always, we are committed to adapting PortDroid to provide the best possible functionality within the evolving Android privacy framework.

What personal data does PortDroid use?

PortDroid does not save any user data on our servers or share any data with third-parties.

The one exception is the analytics library inside the application that is used to share crash reports via Google’s Firebase Crashlytics so that we can improve the stability of the application. This crash data does not include any user identifiable information.

You can choose to disable this crash reporting for additional privacy in the advanced settings (Settings > Advanced Settings > Crash Reporting)
