  2. 2. • 9:00 The Dark Side: Privacy, Dark Web & Hacker Devices Brian Pichman, Director, Strategic Innovation, Evolve Program Pichman walks through the tools that help provide anonymity and some ways to help mitigate the ease of being tracked. He goes beyond private VPNs and Tor Browsing to provide other tips and tricks. He gives an overview of some of the common devices, either hardware- or software-based, that are used by the Dark Side, and some easy-to-use defenses that you and your users can employ to protect yourselves from these attack vectors. Think of it as a Defense Against the Dark Arts class! And bring your device to actually try it out!

  6. 6. Tools For Anonymity Making yourself more “invisible”
  7. 7. Onion Routing, Tor Browsing • Technique for anonymous communication to take place over a network. The encryption takes place at three different times: • Entry Node • Relay Node • Exit Node • Tor is made up of volunteers running relay servers. No single router knows the entire network (only its to and from). • Tor can bypass internet content filtering, restricted government networks (like China) or allow people to be anonymous whistle blowers. • Tor allows you to gain access to “.onion” websites that are not accessible via a normal web browser. • Communication on the Dark Web happens, via Web, Telnet, IRC, and other means of communication being developed daily.
  8. 8. Some History • Originally grew with help from the U.S. Military as a way to communicate without detection. • In 1995 the concept of “onion routing” was born. • The Deep Web was coined in 2001 by BrightPlanet which specializes in locating content within the dark web. • In 2004 the U.S. Naval Research Lab released the Tor code to the public, and in 2006 it was retooled as the Tor Project.
  9. 9. Cloak of Invisibility Anonymous Browsing tools like the Tor Project

  27. 27. BackTrack can get you ALOT • BackTrack was a Linux distribution that focused on security based on the Knoppix Linux distribution aimed at digital forensics and penetration testing use. In March 2013, the Offensive Security team rebuilt BackTrack around the Debian distribution and released it under the name Kali Linux. https://en.wikipedia.org/wiki/BackTrack
  28. 28. Attacks • Man in the Middle • Sitting between a conversation and either listening or altering the data as its sent across. • DNS Spoofing (https://null-byte.wonderhowto.com/how-to/hack-like-pro-spoof-dns- lan-redirect-traffic-your-fake-website-0151620/) set up a fake website and let people login to it. • D/DoS Attack (Distributed/Denial of Service Attack) • Directing a large amount of traffic to disrupt service to a particular box or an entire network. • Could be done via sending bad traffic or data • That device can be brought down to an unrecoverable state to disrupt business operations. • Sniffing Attacks • Monitoring of data and traffic to determine what people are doing.
  29. 29. More Sources • https://www.reddit.com/r/deepweb/ • DuckDuckGo.Com doesn’t track searches • Also lets you search of .onion sites when using TorBrowser to access.
  30. 30. Other tricks • 10 Minute Email • https://10minutemail.com/10MinuteMail/index.html • Temporarily get an email box that’s anonymous and disappears after 10 minutes • Dr Cleaner (Mac) or Eraser (Win) can overwrite files on your computer with “blank” data to make file recovery near impossible. • Tools like Recuva is free softwares to allow you to restore deleted files.
  31. 31. Your Library • Administrative Accounts are easy to figure out if they are something like “administrator” ”root” or “power users”. At the same time, no employee should have their account as a full admin. • Instead, give them their own username for admin access (like brian.admin) • Change the default “login” pages for sites to something that’s not www.mysitename.com/login. Bots look for this and attack. • My Drupal Site login page is www.evolveproject.org/catpower • User Awareness is key to any secure organization. Teach users how to identify potential threats and how to respond quickly. • Avoid shared accounts. One account should only be used by one person.
  32. 32. You • Sites to protect yourself all the time (not free) • IdentiyGuard.com • LifeLock.com • Sites to monitor when breached data gets related (this is free) • Haveibeenpwned.com • Password Management Sites (like lastpass.com) • Don’t have the same password for all your sites. • Don’t write your passwords down on a post-it-note and leave it at your desk

  44. 44. Examples of Hacks/Breaches • An employee/family member allows a hacker to access their machine through: • Email Attachments • Social Engineering • Walking away from their computer unattended • An employee/family member sends information to someone thinking they are someone else • “Hi, I’m the CFO assistant, he needs me to collect all the W2s” • Or more intrusive – • There is an attack on a database or server that then allowed a hacker in (SQL Injection) • There is a brute force attack or someone guessed the password on a key admin account, on servers/networks, etc.
  45. 45. The Costs Of Breaches • This year’s study found the average consolidated total cost of a data breach grew from $3.8 million to $4 million. The study also reports that the average cost incurred for each lost or stolen record containing sensitive and confidential information increased from $154 to $158 [IBM 2016 http://www-03.ibm.com/security/data-breach/] • Data Breached Companies Experience… • People loose faith in your brand • Loss in patrons • Financial Costs • Government Requirements, Penalties, Fees, etc. • Sending of Notifications • Payment of Identity Protection or repercussions. https://betanews.com/2016/02/10/the-economic-cost-of-being-hacked/
