Charity sites are being targeted by credit card fraudsters
NetSafe warns New Zealand charity websites are being targeted by credit card fraudsters
FOR IMMEDIATE RELEASE: Auckland, 16 January 2015
NetSafe is warning New Zealand charities taking online donations to be on the alert after receiving two reports this week of cyber criminals launching automated attacks that attempt to validate large numbers of stolen credit cards.
In the first incident, almost 50,000 attempts were made to rapidly submit fake donations through a website form with the aim being to test which credit cards could be used for subsequent online fraud or sold on to other internet scammers.
More than 2000 successful donations were made resulting in the charity having to enlist the help of their bank and merchant account provider to refund the fraudulent payments. They also spent time dealing with enquiries from cardholders around the world questioning the transactions.
A second incident yesterday saw another charity website hit with 11,000 payment requests resulting in more than 250 donations to their bank account.
In both cases, the automated attacks had been launched from a Brazilian IP address and NetSafe is encouraging charities and other small businesses that take payments online to take steps to secure their websites and contact their bank or payment provider about ways to prevent online fraud.
Online fraud a global problem
“Credit card fraud is an ongoing issue for any organisation that takes payments over the internet,” said NetSafe’s Digital Project Manager Chris Hails.
“The American security company PhishLabs warned that charity websites were being targeted by cyber criminals to validate stolen cards in November last year (see Note 1) and they believe that these smaller organisations have fewer internet defenses in place than larger retailers and are thus an easy target.”
“Being the target of such an attack can mean hours of staff time cleaning up afterwards and could potentially cost your organisation money or find you blocked from taking future donations online,” said Hails.
The warning comes just a week after New Zealand’s Banking Ombudsman predicted that complaints to her office about scams would increase in 2015 (see Note 2). Auckland-based NetSafe recorded more than 8000 incidents in 2014 including a wide range of cyber security issues ranging from phishing attempts to ransomware.
Protect your business online
NetSafe offers the following advice for
charities and website owners:
• Talk to your
bank or merchant provider about how their payment systems
can be used to protect against online
fraud
Enquire about options for monitoring
payments and blocking such large scale automated attacks. If
you can, consider using third party card verification
services from Visa and MasterCard to add a second layer of
protection.
• Talk to your website developer,
IT staff or a security specialist about ways to protect your
site and any payment forms you host
Using SSL to
encrypt information submitted is essential so that forms
operate at an https:// address. Discuss testing your systems
for signs of common vulnerabilities and your options for
fixing them.
• Use a CAPTCHA on your web form
or require an account be created
Technical
solutions like these can potentially slow down automated
software ‘bots’ that are designed to validate card
numbers in quick succession.
• Limit
transaction volumes or website sessions by IP address or
pre-screen payments from high risk countries if you are
seeing fraudulent attempts to donate
Many New
Zealand charities may only wish to accept donations from
Kiwis using credit cards issued by NZ banks. Ask if you can
filter payments by Bank Identification Number (BIN) to
prevent overseas cards being
accepted.
• Consider monitoring traffic volumes
to your website
Talk with your website host
about establishing an alerts services so that you’re aware
if you receive a sudden unexpected spike in
visitors.
“Monitoring any payments received is an
important way to detect fraud on your website. Be on the
lookout for a series of small donations for odd values or
random amounts. Real people tend to donate whole dollars -
$20 rather than $4.73,” said Hails.
If your website has been targeted by credit card fraudsters speak with your bank or merchant provider. You can also contact NetSafe via their freephone telephone number 0508 NETSAFE or report an incident online atwww.theorb.org.nz.
