Why is this ransomware attack different?

Unlike other ransomware families, the WannaCry strain does not spread via infected e-mails or infected links. Instead, it takes advantage of a security hole in most Windows versions to automatically execute itself on the victim PC. According to various reports, this attack avenue has been developed by the National Security Agency (NSA) in the US as a cyber-weapon and it was leaked to the public earlier  in April along with other classified data allegedly stolen from the agency. Until now, a number of hospitals, telecom companies or gas and utilities plants have suffered massive disruptions caused by data being held at ransom. As this ongoing outbreak is affecting countless computer users around the world, we are actively working on a free decryption tool to help victims recover their information without paying the ransom.

MPLS Troubleshooting Tips

Anyone of you having difficulty in troubleshooting MPLS as a beginner? I did some research and take notes for myself and now it is for you to do reference as well. MPLS troubleshooting can be divided into two main steps: 1) Verify routing information flow 2) Verify proper data flow - Routing information flow troubleshooting requires verification of end-to-end routing information propagation between CE routers. - Verification of the routing information flow should be done systematically, starting at the routing ingress CE and moving to the egress CE. - Verification of the data flow should be done systematically, starting at the data flow ingress CE and moving to the egress CE. There are three things to perform basic MPLS troubleshooting. They are, 1) Preliminary steps in MPLS VPN Troubleshooting: - Is CEF enabled? - Are labels for IGP routes generated and propagated? - Are large labeled packets propagated across the MPLS backbone (maximum transmission unit issues)? 2) Verify the routi
