Ngo reports that the Vietnamese security research firm BKIS has determined that the Conficker virus originated in ... wait for it ... China.
The firm's conclusion is based on its analysis of the virus' coding. It found that Conficker's code is closely related to that of the notorious Nimda, a virus that wreaked havoc on the Net and e-mail in 2001. At that time, BKIS determined that Nima was made in China based on the firm's own data.
It's important to note that the origin of Nimda was never verified. Though Nimda contained text indicating that it may have originated from China, this is in no way hard evidence.
