Businesses warned to protect data against possible Russian malware

The government is warning companies to be vigilant about their cyber-security in the wake of Russia's invasion of Ukraine.

The Office of Cyber-Security & Information Assurance says businesses could be targeted by hackers - although it hasn't seen any specific threat yet.

Its advice is for companies to make sure their software is up-to-date and secure, and to stay abreast of the latest information.

The OCSIA says in the past, computer systems worldwide have suffered collateral damage after Russian malware spread beyond its intended target.
