Over a quarter of a million devices used with DVRs around the globe are susceptible to a new botnet its discoverers have dubbed Amnesia . Unit 42 researchers at Palo Alto Networks announced on Thursday their detection of a new variant of the IoT/Linux botnet Tsunami , which they are referring to as Amnesia . The Amnesia botnet looks for an unpatched remote code execution vulnerability affecting Vulnerability-related.DiscoverVulnerability DVR ( digital video recorder ) appliances manufactured by China-based TVT Digital and identified Vulnerability-related.DiscoverVulnerability in nearly identical products from more than 70 global vendors . Unit 42 is claiming Vulnerability-related.DiscoverVulnerability that the flaw is impacting Vulnerability-related.DiscoverVulnerability about 227,000 devices all over the planet , with Taiwan , the United States , Israel , Turkey , and India being the most susceptible . Further , the researchers believe this is the first Linux malware to adopt virtual machine evasion techniques to defeat malware analysis sandboxes . Not only that , should the code recognize it has reached into VirtualBox , VMware or a QEMU-based virtual machine , it will wipe the virtualized Linux system by deleting all the files in file system , the post stated . `` This affects not only Linux malware analysis sandboxes but also some QEMU based Linux servers on VPS or on public cloud , '' the researchers said . The power is in how the malware can exploit the remote code execution vulnerability to scan for , locate and attack vulnerable systems . Once connected , the malware enables the remote attackers to gain full control of the affected device . The researchers speculate that bad actors could potentially use the Amnesia botnet to launch wide-scale DDoS attacks on a scale previously seen in the fall 2016 with the Mirai botnet . Apparently , no patches have yet been issued to address Vulnerability-related.PatchVulnerability the flaw , the researchers said . As to why a patch has yet to be issued to fix Vulnerability-related.PatchVulnerability this year-old flaw , Ryan Olson , intelligence director of Unit 42 at Palo Alto Networks , told SC Media on Thursday that it 's up to the manufacturer to create Vulnerability-related.PatchVulnerability a patch . His team has n't found any evidence they have released one . The vulnerable DVRs are typically connected to closed circuit TV ( CCTV ) equipment , which are often installed in offices and stores , Olson said . `` The people operating these should limit access to those devices from the internet so they are not exposed to potential malicious actors . '' This , he added , is typically accomplished using a firewall that stops the traffic before it reaches the vulnerable device . The fact that the actors behind this malware are using VM-detection mechanisms in a Linux malware family indicates that they likely have prior experience creating malware , Olson explained . The good news is that no large-scale attacks have yet been launched using the Amnesia botnet , though judging by the harm from Mirai , the researchers at Palo Alto warned the damage large-scale IoT-based botnets could do is substantial . They recommended users have `` the latest protections '' installed and to block traffic to Amnesia 's command-and-control server ( listed in their post )

Today , we noticed Vulnerability-related.DiscoverVulnerability a pretty weird security flaw in Windows 10 Mobile . If you are using a Windows 10 Mobile that does not support Windows Hello , your are likely using a pin to secure your device . The pin can be easily set-up from Windows 10 Mobile ’ s Sign-in Options page in the Settings app . However , there ’ s an interesting issue with this system . That ’ s because you can easily remove the pin from the device without having to verify the current pin that ’ s set . For instance , if your pin is “ 2017 ” and someone else gets access to your phone , they can simply remove it without having to verify the pin . This , however , isn ’ t the case when you try to change the pin as the OS will ask you to verify the existing pin first . This may sound like a minor issue , but it actually isn ’ t one — that ’ s because someone can easily lock you out of your own device once they get the initial access ( which , to be fair , can be difficult to attain ) . For example , they can remove the current pin , and set a new one without having to verify the password for the linked Microsoft Account on the device or the pin ( since it ’ s already removed ) . This isn ’ t how the pin-lock system works on Android or iOS . Both of these operating systems require users to verify their pin/password/pattern before they can edit any of the settings related to the pin — including the ability to completely remove the pin from the device . What ’ s even more interesting is that this issue doesn’t exist on Vulnerability-related.DiscoverVulnerability Windows 10 PCs where you will be required to verify the existing pin when you try to remove the pin from a device . As far as we are aware , the issue is impacting Vulnerability-related.DiscoverVulnerability Windows 10 Mobile devices running Windows 10 Mobile Version 1511 , 1607 , and even the latest Insider preview releases . We hope Microsoft will fix Vulnerability-related.PatchVulnerability this issue in Windows 10 Mobile pretty soon , and we ’ ll let you know if and when that happens
