10 TODAY S REALITIES 1 in 5 of all organizations have experienced a cyber attack 3 Months is the time an advanced threat goes unnoticed on a victim s network 2.5 Billion exposed records as a result of data breaches in the last 5 years 62% increase in breaches in 2013 From January 2012 to June 2014, 75% of reported data breaches have occurred at small and mid-sized organizations Up to 98% of Fortune 500 companies have been breached Sources: Forbes, Business Insider, ISACA Global Security Analysis & 2014 Verizon Data Breach Report May 21,

11 SECURITY NOT A KEY CONCERN I don t think we re a real target for hackers May 21,

12 WHAT S ALLOWING SECURITY ISSUES TO PERSIST Generally weak security standards Up until recently security was often an afterthought Focus on Perimeter Security Relatively little monitoring detection and prevention at endpoints Ignoring where sensitive data actually resides Security Awareness People are the weakest link of all May 21,

15 EVOLVING RETAIL CYBER THREATS

16 HIGH PROFILE RETAIL BREACHES August 2014: Payment data system was breached. Malware installed on cash register system across 2,200 stores syphoned credit card details of up to 56 million customers. Could be largest breach ever recorded affecting all 2,200 stores. Profits down $50M over last quarter and breach will cost them $62M. November 2014: Hackers gain access to Sony network after Wide-ranging hack of potentially every piece of data held by the company, including: unreleased films & scripts, employee social security numbers, salaries and health check results, as well as sensitive internal business documents relating to lay-offs, restructures and executive salaries. The estimated breach cost to Sony is $100M. February 2014: Hackers who raided the credit-card payment system of Neiman Marcus set off alerts on the company s security systems about 60,000 times as they slunk through the network. The hackers moved unnoticed for more than eight months, sometimes tripping hundreds of alerts daily because their card-stealing software was deleted automatically each day from the payment registers. 1.1 Million customers were affected and cost the retailer $4.1 Million in legal fees, investigations, customer communications and credit monitoring subscriptions December 2013: Hackers installed software installed on credit card machines that customers use to swipe magnetic strips on their cards when paying for merchandise at Target stores. As a result 40 million credit cards and 70 million records of personally identifiable information stolen. The current estimate of breach cost to Target is $148M. "Cyber attacks are growing every day in strength and velocity across the globe. It is going to be a continual and likely never-ending battle to stay ahead of it.

22 HACKING TACTICS AND METHODS

23 TACTIC #1 SOCIAL ENGINEERING Hi This is Joe from your Help Desk department, please give me your PC id and password, so I can evaluate the issue in your system. There s no patch for human nature May 21,

24 SIMPLE HACKS TO PERSONAL ACCOUNTS 1. Called Amazon and added a fake CC# to someone s account 2. Called back and claimed to be locked out used CC# they just added to verify account. Amazon issued verbal temporary password. Hackers logged in to get last 4 digits of real CC# 3. Called Apple claiming to have forgotten Apple I-Cloud Password. Apple asked for last 4 digits of CC# as a security check. 4. Locked out user 5. Used accounts for shopping and on-line vandalism Total time span = 45 Minutes May 21,

25 HOW WE HACKED A COMPANY WITH NO TECHICAL SKILLS May 21,

26 TACTIC #2 SMASH & GRAB Goal: Compromise as many systems as possible # HOSTS COMPROMISED Detection Threshold Signature becomes available TIME May 21,

27 HACKING TARGET WITH MALWARE May 21,

28 WHAT HAPPENS WITH STOLEN CREDIT CARDS? Hacker Carder Website Carder Gift Cards / Prepaid Buys Goods Goods delivered to Mule and Shipped Carder resells goods May 21,

29 WHAT IS YOUR HACKED DATA WORTH? CVV 3- digit Bank a/c details Bank a/c details PayPal/eBay account $ Full package of identifying info (name, DOB, etc.) Credit card (old) Health credentials Used to buy drugs or make fake insurance claims lowest Credit Card (fresh) Average Highest Source: informationisbeatutiful.net May 21,

30 TACTIC #3 UNDER THE RADAR Goal: Compromise fewer, highvalue targets avoid detection # HOSTS COMPROMISED Detection Threshold TIME May 21,

31 HOME DEPOT A DIFFERENT TYPE OF HACK Exposed a decade-old Windows XP vulnerability (used at most POS systems). Malware allowed for an exploit known as RAM Scraping. Attack siphoned off CC data and s for 5 Months (April September 2014). 56 Million cards leaked Why didn t Home Depot upgrade POS? Cost of upgrading 2,200 stores is expensive and would have taken months. May 21,

32 TACTIC #4 ADVANCED PERSISTENT THREAT An advanced persistent threat (APT) is a set of stealthy and continuous computer hacking processes, often orchestrated by human(s) targeting a specific entity. APT is the new black May 21,

33 HACKING RSA HOW THE WORLD S TOP SECURITY COMPANY WAS BREACHED Part 1: Homework Part 2: Targeted Phishing Scam titled Recruitment Plan 2011 Classified as Spam and ended in Junk folder At least one user found it interesting enough to retrieve it May 21,

35 TOP 5 CYBERSECURITY MYTHS

36 CYBER MYTH #1 CYBERSECURITY RISK IS OWNED BY THE IT DEPARTMENT CYBER is a board-level/ C-level issue. Questions Boards Should Be Asking: What digital assets do we maintain? What are our main cyber-related risks? Third parties Hackers / espionage Inside threats Etc. What have we done to assess our cyber risks and vulnerabilities? What mechanisms are in place to protect, detect, respond and recover from cyber incidents? Are these methods in line with our risk tolerance? May 21,

37 CYBER MYTH #2 CYBERSECURITY IS A TECHNICAL ISSUE Cybersecurity requires governance Drivers of Security MONITOR Business Environment Threats Compliance Requirements Cybersecurity Processes & Controls DIRECT Security Protocols Infrastructure Computer Settings May 21,

38 CYBER MYTH #3 I NEED A PEN TEST Cybersecurity Hierarchy 04 Security Information & Event Management, Risk Assessments, Identity Management Holistic 03 Log management, Intrusion protection, Monitoring solutions, Pen Test, Wireless, Storage security, DLP Enhancing 02 Anti-spam, security, Remote access/vpn, Encryption Vulnerability Management, Recovery Important 01 Anti-malware / Anti-virus Network Firewalls Patch Management Access Controls Focus on fundamentals first Fundamental May 21,

39 CYBER MYTH #4 CYBER THEFT IS ONLY ABOUT CREDIT CARDS Other data is considered high-value 33% increase of non payment card data from Source 1: 2014 Trustwave Global Security Report May 21,

40 CYBER MYTH #5 THERE IS NO ROI ON SECURITY Security is an enabler Security is an expectation for your customers and employees Security needs to be scaled to the cyber threats affecting your business If you decrease the number and extent of security incidents you will save money May 21,

41 PROTECTING YOUR DATA

42 WHAT WE HAVE SEEN TOP WAYS HACKERS OBTAIN DATA Sensitive data on company intranet / Internet Admin rights on servers Open folders Weak Credentials Insecure Password Storage Unpatched / legacy firewalls and operating systems May 21,

43 HOW TO AVOID BEING THE NEXT TARGET (PUN INTENDED ) Know your information assets Don t boil the ocean with security controls do the basics and do them well: Patch management Good authentication Perimeter security Malware and anti-virus Security awareness and training!!! Don t forget these blocking & tackling IT controls: Backups Periodic vulnerability / security assessments Monitoring Response plan is critical May 21,
