Malware, short for malicious software, can be difficult to detect. It is an intrusive program that fraudsters try to install on your devices or network.

It can be hidden in emailed links, attachments or disguised as genuine software and can seriously corrupt data, systems, devices or networks.

Through malware, fraudsters will attempt to disrupt or gain unauthorised access to your device or network, in order to obtain sensitive information about you or your business.


  • Unusually slow loading of pages or the appearance of strange error, pop-up or “Please Wait” messages
  • SMS Protect messages containing incorrect or unrecognised payment details
  • Requests for personal information like credit card details, phone numbers or drivers licence
  • Unfamiliar banking processes such as requests to verify payments, enter SMS or token codes e.g. adding a payee or signing into your banking, when you are not performing this activity
  • Unusual changes to the Online Banking pages, e.g. displaying upgrade or 'under maintenance' messages
  • Irregular webpage layout such as missing fields or additional buttons

Malware can cause extensive systemic damage including loss of personal information, intellectual property, unauthorised transactions and loss of confidential data.

Malware can also cause day-to-day operational impacts to you or your business, including deletion of critical information which has not been backed up.

The best practices to avoid malware are preventative.

  • Install security software, such as Trusteer Rapport, which is designed to protect your device or network against malicious software, and help guard against online identity theft and fraudulent transactions.
  • Don’t download or purchase unauthorised software.
  • Back-up your files regularly.
  • Don’t open or download any files or programs unless you have first validated the source.
  • Think before you click on any email or SMS links, attachments or website pop-ups.

Listen to your instincts. If it doesn’t ‘seem right’, report it.

'ASSURE' yourself and stay 1 step ahead of the fraudsters:

Abort what you are doing - close the browser or exit the app
Seek security software updates
Scan your devices to remove threats
Use another device, check for anomalies and payment history
Report any suspected fraud immediately
Enquire further if in doubt

If you don’t currently have security software, we suggest you use one of the free security tools available online. If you believe your system has been compromised, or notice a transaction you did not make, contact us immediately on 132 032.
