2 What do these companies/organizations have in common?

3 Crime Syndicates New Mafia** (Hide in plain Site) Huge source of profits Nation States Chinese Russia Turkey North Korea Iran India WHY is Hacking on the rise? Hacktivist (Activism Hacking) Groups like Anonymous Groups that want to demonstrate their dissatisfaction with powerful organizations Businesses or Governments Easier than Ever to Create and Distribute Malware Malware toolkits non-developers can create and distribute malware

4 Malware Toolkits (Malware as a Service) 1. Sign up for the TOX Ransomware Service. The hosting Service is free. (You just have to register on the site.) 2. For Anonymity purposes - TOX uses TOR (Onion Router) and Bitcoin Over 1 per Week in 2015! 3. Once you register for the product, you can create your malware in three simple steps: 1. Enter your desired ransom amount Note the TOX Ransomware Service takes 20% of the ransom as commission 2. Enter your cause 3. Submit the captcha (To make sure you aren t a robot (comical), and download your executable malware 4. This process creates an executable of about 2MB that is disguised as a.scr (script) file which can be made to look like any document such as a PDF. The attacker distributes and installs the malware as they see fit. 5. The TOX site (on the TOR network) will track the number of installs and profit. 6. To withdraw funds, you need only supply a receiving Bitcoin address for the transfer (Malware as a Service - MaaS)

5 Targeting Small Businesses Small/Medium businesses often lack adequate security measures making them easy targets Small/Medium businesses don t have the resources to fight back so ransoms are paid at higher rates than larger enterprises Small/Medium businesses offer entry to bigger businesses The famous Target attack in 2013 was actually hacked through it s HVAC vendor Small/Medium business offer a much lower risk to attackers FBI/Secret Service can t investigate the sheer amount of attacks that happen, so they focus on the largest ones leaving small businesses to fend for themselves Malware Ratio in by Industry (Source: Symantec Internet Security Threat Report April 2016 Volume 21)

7 Common Attack Vectors Know your enemy and know yourself and you can fight a hundred battles without disaster. Sun Tzu (Attackers try to trick internet surfers into downloading malware) (Attackers try to decode a password or pin number through trial and error) (Attacker overloads a server with more requests than the server can process) (Attackers intercept data before it can be encrypted by SSL) (Attackers scan for open ports through which they exploit to gain access to your systems) (Attackers redirects users to bogus websites when they are trying to access a legitimate one) (Attackers leverage software/hardware bugs/flaws to gain access to your systems) (Phishing, Social Engineering, Compromised Devices, Advertisements, etc.) (Source Mcafee Labs, March 2016 Security Report)

10 What do these things have in common? Layers! The best strategy against today s threats is to employ a Defense-in-Depth Layers Strategy: Deploy multiple, overlapping, and mutually supportive defensive systems to guard against single-point failures in any specific technology or protection method

20 Zero-day Malware and Advanced Persistent Threat (APT) Prevention Predictive behavior recognition technology detects APTs and malware Dwell time alerting and reporting instantly reveals any endpoint infection Full visibility of any infection by endpoint with full reporting capabilities Always Protected and Up-To-Date No definition or signature file updates to manage Every endpoint protected individually (on and offline) All users instantly and collectively protected against new threats Fast and Easy to Deploy Never slows system performance Takes an average of 5 seconds to install and be fully operational World s smallest endpoint security agent (<750KB) Idle CPU usage of 0.10% 10.8% during scans Initial full system scan uses <15 MB of RAM Scheduled scans take an average of <30 seconds No conflict design so the agent can run alongside other security software No definition or signature Updates to Deploy or Manage Easy to Manage Low Operational Costs: No on premise hardware or software Full remote management of all endpoints Endpoint infection rollback and auto-remediation Highly automated management and customizable reporting Webroot leverages the Cloud to provide always up to date continuous real-time protection regardless of the users location. Anytime a file is modified, Webroot logs the change and validates if it is a known threat then takes action. Because all changes are logged, any changes that the WebRoot cloud later determines to be a threat (Zero Day attack) can be rolled back and mitigated Internet

IF the Domain and resulting IP is known good, the connection is allowed 2. IF the Domain and resulting IP is known bad, the connection is blocked 3. IF the Domain and resulting IP is unknown to Cisco Umbrella, the response to the client is an IP Address for Cisco Umbrella vs the actual web server hosting the domain.
