What is ”Phishing” ?
Now you got an e-mail and it says,
- Your credit card has expired.
- It needs to verify your account.
The mail has also a link to a certain website, and you jumped to the link.
The site says that you should check your account and try to input your information.
The site domain looks like your favorite site’s (e.g. arnazon.com : NOT amazon.com), has SSL server certification, and GUI looks very similar to the original site.
A certain number of you might input your account information, but the e-mail and whole of the site are FAKE.
If you “submit” your information, your account (or credit card) will be used by phishers.
How can you prevent damage by phishing ?
It is said that you might prevent your damage by…
- Setting your e-mail client software to prevent spam mails.
- Some mails through filters in the software.
- Check a sender domain.
- We don’t know what domain is safe.
- Check if a link string equals destination URL.
- Usually there is no time to check it.
- Check if a linked site has an SSL.
- More than half of phishers has a site with SSL.
