BAE Systems warns about shape-shifting strain of Qbot malware

The incident response team at BAE Systems is warning of a strain of the virulent Qbot malware that has hit thousands of public sector computers around the world.

The malware – also known as the Qakbot botnet – first appeared in 2009 and was uploading 2GB of stolen confidential information to its FTP servers each week by April 2010 from private and public sector computers, including 1,100 on the NHS network in the UK.
