Australian security experts have warned people to keep an eye out for a ransomware variant called CryptoLocker that will infect systems and encrypt files via malicious links in spam emails.
Those who have been infected by the malware have been ordered to pay a ransom in order to unlock their system and retrieve their files. The problem is that even when CryptoLocker is removed, the files are not always restored.
IT security expert Michael Sentonas warned that it is vital companies at risk have great backup systems in place and ensure that their Windows patches and antivirus software is up to date.
He said that CryptoLocker is a global threat targeting companies all over the world.
According to Computer World, the best way to prevent infection is to avoid opening email attachments from unknown people. It is also recommended caution be taken when visiting unknown sites and unlicensed installations be avoided.
