[$] Vulnerability hoarding and Wcry

A virulent ransomware worm attacked a wide swath of Windowsmachines worldwide in mid-May. The malware, known as Wcry, Wanna, orWannaCry, infected a number of systems at high-profile organizations aswell as striking at critical pieces of the infrastructure-like hospitals, banks,and train stations. While the threat seems to have largely abated-fornow-the origin of some of its code, which is apparently the US National SecurityAgency (NSA), should give one pause.
