  1. Remote Access Review Cyber Security Threats Bob Lukens December 1, 2010 

  2. Content • Why Us? • Ways and Means • Examples • RE: Remote Access • Potential Impacts

  3. Why Us? Not “Mission-Targeted” – drive-by attacks • Target of Convenience – random scans • Bragging Rights / Curiosity • Feral Code • Financial Gain – our computers or our money Targeted – who we are or appear to be • The Friends We Keep – Guilt by Association • Proprietary technical and scientific information • Misinformed spies • Politics • Disgruntlement

  4. Ways and Means Get a seat inside … • Compromise Passwords – phishing, cracking, network sniffing, Bluetooth sniffing, shoulder surfing, keyboard sniffing, credential theft (Zeus virus) • Install Code – via Adobe, IE, Outlook, malicious web pages, infected media, trojaned applications • “Zero Day” vulnerabilities or unpatched systems • Follow the path from infected laptop or remote machine Then look around • Scan local net and shares • Install root kit – hide, record key stokes, wait to escalate privileges, collect credentials, call home, reprogram firmware, complete the ‘mission’

  5. Examples • Nuclear plant controls infected (Stuxnet, Iran 2010) • $960,000 transferred to Chinese bank (UVa 2010) • 12 passwords compromised for a spam bot (JLab 2010) • Webmail Phishing with follow-up internal mail • ‘I love you’ virus on financial systems (JLab ~2003) • Wipe and load ~5 machines per month (JLab 2010) • Virus detected on ‘magdev0’ (JLab ~2005) • Licensed PM application update infected (JLab ~2007) • IOC rebooted by “curious” hacker (JLab 2002) • Sniffed password, installed IRC, got root on Linux box

  6. RE: Remote Access Unmanaged machines (travel, home, at remote user sites, public, smart phones) are more likely to be compromised Compromised machines • Like portable media, could infect colleagues’ machines when brought on site • Provide no assurance that user’s password is secure • Make any authentication suspect

  7. Potential Impacts • Loss of process control • Safety issues, hardware damage • Loss of computational resources • Loss of research time • Loss of data that was not backed up • Loss of reputation and credibility
