Understanding Skimming In Cyber Security
Skimming in cyber security refers to the theft of credit/debit card information using a small device or software. Cybercriminals install these skimmer devices on ATMs, gas station pumps, or point-of-sale (POS) terminals. When you swipe your card, the skimmer captures card details without immediate detection.
There are two main types of skimming:
- Physical Skimming Devices:
- Placed over existing card readers.
- Collect card data when a card is swiped.
- Often paired with hidden cameras to capture PINs.
- Example: An overlay skimmer on an ATM.
- Software-Based Skimming:
- Injected into payment systems.
- Captures data during transactions.
- Harder to detect because of its virtual nature.
- Example: Malware placed on POS systems.
Common Skimming Locations
Certain locations are more prone to skimming attacks:
- ATMs: Skimmers are often placed where cards are inserted.
- Gas Station Pumps: External devices installed on card readers.
- Retail Stores: Compromised POS terminals at checkout.
Prevention Measures
We can protect ourselves from skimming by following these precautions:
- Inspect Card Readers: Look for loose or tampered parts.
- Use ATMs In Safe Locations: Choose those inside banks.
- Monitor Bank Statements: Regularly check for unauthorized transactions.
By understanding and implementing these protections, we reduce the risk of falling victim to skimming attacks.
How Skimming Attacks Occur
Skimming attacks involve criminals who clandestinely capture card information during transactions. Let’s explore the techniques used and the key elements targeted.
Common Techniques Used
- Overlay Skimmers: Criminals place overlay devices on top of existing card readers. For example, they might attach a fake keypad to an ATM, which records keystrokes.
- Deep Insert Skimmers: Devices inserted deep into card readers capture data when customers insert their cards. ATMs and gas pumps are common targets for these tools.
- Shimmers: Microchips placed inside card readers capture data from chip-enabled cards. These tiny devices are harder to detect than traditional skimmers.
- PIN Capturing Cameras: Hidden cameras record customers entering their PINs. Often, criminals hide these cameras in inconspicuous places like brochure holders or light fixtures.
- Card Data: Attackers target the magnetic stripe or chip data. This data includes the primary account number (PAN), cardholder name, and expiration date.
- PIN Codes: Cybercriminals seek to capture customers’ PINs. Without the PIN, accessing the funds becomes challenging.
- CVV/CVC Numbers: The card verification value (CVV) or card verification code (CVC) on the back of cards is a prime target. This information is essential for online transactions.
- ATM/Payment Terminals: Skimmers specifically target ATMs, gas station pumps, and retail payment terminals. These locations experience high card transaction volumes.
By understanding these techniques and elements, we can better protect ourselves from skimming attacks.
Real-World Examples Of Skimming
