A new framework from a lab in Switzerland could help prevent malware like Petya from spreading, but would also make it difficult — if not impossible — for governments to force software companies to deliver backdoored software updates in secret. The Petya ransomware, and its wiperware variant NotPetya, spread on the wings of a software update unwittingly issued by Ukrainian accounting software company M.E. Doc. An attacker, who many believe to be agents of the Russian government, owned M.E. Doc’s network and injected malicious code into a legitimate software update. This new proof-of-concept technology, dubbed “Chainiac” by the Decentralized/Distributed Systems (DEDIS) lab at the Swiss Federal Institute of Technology in Lausanne (EPFL), offers a decentralized framework that eliminates such single points of failure and enforces transparency, making it possible for security analysts to continuously review updates for potential vulnerabilities. “What Chainiac is trying to do,” Bryan Ford, leader of the group that […]
