Project WestWind “Hactivists” focused on hacking to bring awareness for what they consider to be the greater good Team GhostShell has made successful dumps prior to Project West Wind IT Wall Street: Dumped 50,000 accounts to support the occupy Wall Street movement Project Dragonfly: Dumped 200,000 accounts to support freedom of speech in communist countries GhostShell was able to take advantage of vulnerabilities in the web applications of the targeted universities to gain access to their servers The vulnerabilities were most likely exploited using SQL injection The attack took up to four months to prepare according to Aaron Titus of Identity Finder (Chief Privacy Officer) THE ATTACK! SQL Injection: A code injection technique that exploits a security vulnerability in a website's software. The Damage Reputation: Anytime there is a data leak, the reputation of the institution is affected Reputation: GhostShell also found many of the machines were already exploited existing exploits. Some of these stored credit card information. Cost: Notification and credit monitoring for those whose information was leaked Sample of Affected Universities University of Michigan (7 servers) University of Wisconsin (4 servers) Cornell University (3 servers) Tokyo University (4 servers) Stanford (2 servers) Cambridge (2 servers) Arizona State (3 servers) HOW NOTRE DAME AVOIDED THE INCIDENT Vigilantly scanning all web applications using tools such as HP Webinspect Limited the exposure of public facing servers with the zone network project and other efforts across the university Luck? WILL GHOSTSHELL GET CAUGHT? It is unlikely that anyone from team GhostShell will get caught. The team used TOR (anonymity network) to extract and dump the data. This allowed them to mask their location through a network of anonymous proxies around the world. QUESTIONS YOU ASKED HOW DO NET IDS GET COMPROMISED?
