3 Agenda Global Data Compromise Landscape Modus Operandi of a Typical Skimming Attack Safeguarding Against Skimming Responding and Reporting a Skimming Incident Key Takeaways 3

4 Global Data Compromise Landscape 4

5 Fraud Transitioning to Other Channels Targeting of older systems such as automated fuel dispensers, and ATMs Fraud and attacks will continue in CNP / e- commerce channels Attackers will exploit insecure websites and mis-configured security settings Internet facing websites at-risk Scan for vulnerabilities Be aware of OWASP Top 10 OWASP_Top_Ten_Project AFD EMV liability shift in October 2020 Stations in remote locations often targeted Skimmers and overlays more sophisticated and harder to detect Regularly check pumps for devices Review POS for overlays Know who to contact if known or suspected attack ATM EMV liability shift in October 2017 Overlays and cameras are more sophisticated Remote locations at higher risk Regularly check ATMs Ensure software is kept up to date Know who to contact if known or suspected attack 5

6 Card Skimming: ATM Trends Skimming continues to be the #1 cause of fraud loss on ATMs Criminal techniques have grown increasingly sophisticated and diversified to avoid anti-skimming defenses An arms race: - Industrialization - Avoidance techniques - Sabotage - Side Channels 6

7 Rise in Skimming Attacks Criminals are targeting mag stripe data Criminals are shifting their attacks to skimming Increase in report skimming attacks in the news Criminals are targeting: Self-checkout terminals Automated fuel dispensers White-label ATMs Increasing in sophistication of attacks and technology All stores targeted regardless if they are 100% EMV enabled Overlays 3D printers leveraged by criminals Placed in seconds not minutes as with physical swaps Easier to deploy in large numbers 7

8 Modus Operandi of a Typical Skimming Attack 8

9 Overlay Examples 9

10 Shimmers 10

11 Shimmers Not the Makeup kind Easy to Deploy Targeting EMV data (static in nature) Issuers who do not use dynamic cryptogram are at risk of fraud/abuse (SDA vs. DDA) Shimmed data may be used fraudulently via non-traditional channels E-commerce fraud, social engineering, force posting fraud, offline posting, online banking password reset 11

12 Deep Insert Skimmers Peering into the ATM future Battery powered Wireless capable Targets mag-stripe data Pin hole camera separate Easily deployed 12

13 Indicators of Compromise AKA Indicators of a skimming device Sticking Buttons Stylus pen wont fit in its holder (due to skimming overlay) Tampering or damage to pumps Brute forcing of key locks to gain access Security tape is altered Hard to insert card into an EMV dip terminal 13

14 Staying ahead of the trends Keep in mind that most devices are Bluetooth, just because a device is recovered doesn t mean the risk is mitigated Allows devices to stay on longer, drive up; download data and drive away (recent cases support this) Placement of devices could have been placed prior, so further investigation is needed Video is key to identifying a WOE Remote wiping of data Cashouts using mobile phones Preservation of evidence Reporting of incidents to local working groups such as LE, Dept. of Agriculture, commerce groups. Know who to contact and when Awareness of risk is key Proximity to highways Poorly lit pumps Not manned 24/7 Use of lead lined bags. Inform LE of new trends and risk factors Thwarts fraudsters from deleting evidence remotely 14

15 Safeguarding Against Skimming 15

16 Device Inventory Management Daily checks of POS terminals Use teams when inspecting devices Maintain a log of devices and their locations within the business Use unique markings/stickers on your devices to quickly identify overlays Utilize tamper screws or cable locks Identify key risk areas where attacks may occur High volume Unattended Areas with limited visibility 16

17 Use of Contactless Card Readers to Minimize Skimming Risks Magnetic Stripe Vulnerabilities Contactless Security Benefits Markets that use magnetic stripe are more vulnerable to counterfeit EMV chip cards reduce the risk Card skimming still occurs in EMV markets, because the data can be used in non-emv markets Reduces the risk for card data to be skimmed since there is no dip or swipe Excellent migration properties Just one solution reduce the risk 17

18 Always Use PCI Approved Devices Follow Visa deployment requirements for use of only PCI approved PIN Entry Devices (PEDS) Go to for Visa program rules As a best practice: Use PCI approved Unattended Payment Terminals (UPT) or other solutions with PCI approved modules Encrypting PIN Pad, Card Reader etc. Use devices that are PCI approved for Secure Reading and Exchange of Data (SRED) 813 various devices listed on the PCI PTS list 18

19 U.S. Automated Fuel Dispenser (AFD) Deadlines EMV and PIN Security Upgrade AFDs to meet EMV and PIN Encryption standards: 1. EMV Liability Shift for U.S. AFDs October 1, Proposed sunset of Single DES (SDES) at U.S. AFDs October 1, 2020 Visa policy allowing SDES at AFDs ends October 1, 2020 Visa announcing details in early March PIN Pads using SDES must be addressed by deadline May use either Triple DES or AES for PIN encryption Adopt a touch once approach to achieving compliance 19

20 New AFD Acceptance Best Practices Visa Payment Acceptance Best Practices for U.S. Retail Petroleum Merchants Geared toward the actions and decisions most pertinent to retail petroleum owners and operators in the U.S. Includes security best practices and on-the-job support tools for attending managers and employees 20

21 Responding and Reporting a Skimming Incident 21

22 Responding to a Skimming Incident What to do if a skimmer is found Do not approach or confront anyone who looks suspicious Might be installing or removing a skimming device May be armed and dangerous Document and take pictures of the skimming device as-is Document before and after removal Document date/time Use protective gloves to remove the device Criminals may leave DNA on device Keep in protective bag and store securely Review CCTV for surveillance of suspects Contact the local authorities and the U.S. Secret Service (U.S.S.S.) U.S.S.S is the law enforcement branch responsible for investigating these crimes Notify your acquirer who will coordinate the investigation with Visa 22

23 How to Report a Compromise to Visa Review Compromised Guidelines Complete Questionnaire Send to Visa / Acquirer 1. Complete Incident Questionnaire Issuers send to Visa Fraud and Breach Investigations Merchants send to Acquirer (who will forward to Visa) 2. Skimming incidents often involve the compromise of highly sensitive PIN data 3. Issuers must be notified of the potential at-risk accounts quickly 4. Try to determine the potential Window of Exposure of the event 5. Pulling at-risk accounts Issuers pull and send compromised accounts to Visa via CAMS* Acquirers pull and send in the compromised accounts on behalf of the merchant via CAMS 6. Visa will distribute the at-risk accounts to the affected Issuers via CAMS * Note Most Issuers are set up as CAMS receivers only, send to VAA_VRM@Visa.com to be a submitter 23

24 Key Takeaways 24

25 Conclusion and Recap: What to Expect Recognize that criminals are targeting mag stripe data and transactions Skimming devices are becoming more sophisticated Understand how to identify different types of skimming devices Learn best practices for safeguarding against skimming attacks Conduct regular, ongoing training for current and new employees Know what to do if a skimmer is found and how to report a suspected compromise We expect these types of attacks to continue These attacks will not be limited to instore Key to mitigating and preventing additional data loss is having a strong response plan in place 25
