BAE Systems Warns About Shape-Shifting Strain of Qbot Malware (computerweekly.com)
Warwick Ashford, reporting for ComputerWeekly: Qbot malware will become a potent threat, facilitated by exploit kits for initial infection and automated to gain maximum victim count, warns BAE Systems. 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. A modified version of the malware has resurfaced that is believed to have infected more than 54,000 PCs in thousands of organisations around the world and added them to its botnet of compromised machines, with 85% of infections in the US.
That's not shape-shifting malware. That's someone releasing a new version of the same malware. Real shape-shifting malware exists, but the term for it is polymorphism. It's been around for decades.
