Hackers go after the weak link. Since the bank is a formidable opponent (remember I work there) they prefer to go after a softer target. You and your computer fit the bill nicely. Many users have a tendency to click on links without considering where it is sending them. Combine that with web page addresses that can be disguised or take you to an unexpected site. New security vulnerabilities in computer systems and software packages often result in exponential increases in the number of attempted attacks.
Tip #1 Do not be the soft target.
Do not click on links to get to your bank site. Always use your bookmarked site. Attackers will buy websites that are close misspellings of actual sites.
Tip #2 Do not be afraid of making changes to your computer.
Many users are unwilling to enable or disable functionality as required to secure their web browser. That is OK because I will show you how to configure a separate browser just for online banking.
Tip #3 Never send your bank information via email or in any kind of online form.
The bank already has this information and they do not need it again. If in doubt pick up the phone and call the customer service number on the back of your ATM card.
Tip #4 Ask your bank for help.
Some banks will give you software to help secure your PC and even help you configure it. Also they can send you alerts if a large transaction is done on your credit card or checking account.
