Chinese firm admits its hacked products were behind Friday's massive DDOS attack Hangzhou Xiongmai Technology, a vendor behind DVRs and internet-connected cameras, said on Sunday that security vulnerabilities involving weak default passwords in its products were partly to blame. ... Because these devices have weak default passwords and are easy to infect, Mirai has been found spreading to at least 500,000 devices, according to internet backbone provider Level 3 Communications. ... Xiongmai says it patched the flaws with its products in September 2015 and its devices now ask the customer to change the default password when used for the first time. But products running older versions of the firmware are still vulnerable. To stop the Mirai malware, Xiongmai is advising that customers update their product’s firmware and change the default username and passwords to them. Customers can also disconnect the products from the internet. ## Note: the company's web site does not (yet) show a press release. Appears the information was sent to IDG via email.
