Hacking

How to protect your device against hackers to how get help if cybercriminals gain access to your details.

Hacking is when a scammer uses technology to get your personal information. They can break into and take over your computer, mobile device or network.

Hackers use this method to steal your identity and gain access to your personal files, bank accounts and credit cards.

About device hacking

Cyber criminals can hack into your device or network by:

  • tricking you into installing malicious software that tracks your activities and locks your files
  • taking advantage of weak passwords, old anti-virus software and non-secure WiFi connections

Once in, hackers can take over your phone or laptop and demand ransom to unlock your device. They will have access to your passwords and personal information that they can use for illegal activities.

Signs your device has been hacked

Your device might have been hacked if:

  • you can't log in to your device, emails or other online accounts
  • there are new, unfamiliar looking icons on your device
  • your files are missing or have been moved
  • there are pop ups appearing on your screen asking you to click OK or Close
  • there are unexplained transactions and money missing from your bank account
  • your phone is suddenly showing SOS only.

Advice to protect yourself from hacking

You can take steps to protect your device and personal information from hacking:

  • keep your devices up to date with anti-virus and anti-spyware software and firewalls.
  • enable multi-factor authentication on your accounts. Learn more about multi-factor authentication from the Australian Cyber Security Centre(opens in a new window).
  • avoid using public WiFi and public computers when accessing personal information.
  • create passwords that aren’t easily guessed by others. Update your passwords regularly and don't save them on your device.
  • don’t open attachments or links in emails, text messages or social media messages from people you don’t know. You can just delete them.
  • be wary of websites offering free downloads of games, movies, music, or adult content. These will often install malicious software without you noticing.

If your device or network have been hacked

If cyber criminals have hacked into your device or network, they have access to your personal details. These include your account login details, personal banking information, passwords and identification information.

Act fast to minimise the damage:

  • Disconnect the device from the internet or network. This may stop the issue getting worse or spreading between devices and networks.
  • Get an IT professional to check and treat your device or network to:
    • remove any illicit software
    • improve device and network security.
  • Run existing anti-virus or anti-malware software to check and remove viruses or malware.
  • You might need to reset your hardware and software to factory settings. Your device may need new software (ask professional IT advice first).
  • Change passwords to accounts that may have been compromised.
