Alert Priority Moderate

Australians are among the nationalities being targeted by a new variant of the well-known Carberp banking malware that aims to steal financial information from users’ computers.

While the Carberp.C variant uses a number of tools to mask its presence, recent updates from antivirus software providers should detect it. You are advised to update your antivirus software at the earliest opportunity to reduce the risk of your computer being infected by Carberp.C or other malware.

Staying safe

Carberp.C has been observed spreading through malicious attachments to spam emails sent largely to Australian users. These attachments pose as invoices contained in .zip files.

You are advised never to open or reply to spam emails and to simply delete them. If you inadvertently do open a spam email, do not open any attachments or click on any links.

Previously, a modified version of Carberp had reportedly been used to target the customers of major Australian banks by effectively taking over online banking sessions. Customers were infected when they clicked on pages that redirected them to malicious web sites.

You are also advised to be careful when browsing the internet and never click on untrustworthy links.
