The PSNI is urging Northern Ireland computer users to protect themselves against malicious software that could be costing the UK millions of pounds.

A campaign by Get Safe Online is highlighting action taken by the National Crime Agency to combat the threat, which will give the UK public a two-week opportunity to rid and safeguard themselves from two distinct forms of malware known as GOZeuS and CryptoLocker.

GOZeuS (also known as P2PZeuS) has been assessed as responsible for the fraudulent transfer of hundreds of millions of pounds globally. Recent intelligence suggests over 15,500 computers in the UK are currently infected, with many more potentially at risk.

"Members of the public can protect themselves by making sure security software is installed and updated, by running scans and checking that computer operating systems and applications are up to date," a statement from the PSNI said.

"Individuals may receive notifications from their Internet Service Providers that they are a victim of this malware and are advised to back up all important information – such as files, photography and videos. Businesses should also test their incident responses and business resilience protocols and work with their IT departments or suppliers to educate employees on the potential threat."

The NCA alert is part of one of the largest industry and law enforcement collaborations attempted to date. Activity in 11 countries, led by the FBI in the US, is reported to have weakened the global network of infected computers, meaning that action taken to strengthen online safety can be particularly effective.
