We start our series on Phishing Emails. They are dangerous because they generally appear to come from a reputable or even trust worthy source (e.g. your friends and work colleagues) and more so they are difficult to block by your security protection software.
What are Phishing Emails?
Phishing emails are fraudulent emails that masquerade as a reputable (e.g. eBay, Paypal, banks etc.) or trust worthy source (e.g. your family and friends). The emails attempt to induce you to reveal personal or sensitive information such as passwords and credit card details.
The way a phishing email works is firstly, the scammer will infect a host of innocuous web sites with their own code. They may plant some programs which attack the vulnerability on your computer or create a fake website that looks like a legitimate one. Then they will send you an email that masquerades as if it comes from someone you know or some reputable companies. Their objective is to portray trust and to deceive users to follow the links or instruction on the emails.
Phishing is a continual and growing threat and is difficult to detect by common computer security software. The threat grows even larger in the social media space such as Facebook and Twitter.
The Australian government has a number of web sites designed to promote online safety:
We will show you a number of common phishing examples:
- Australia Post – You’ve got a parcel
- Australian Tax Office – Tax Refund Confirmation
What should you do?
- Always be suspicious of unsolicited emails.
- Do not respond to emails that request a password or financial information.
- Do not click on any link or open any attachment unless you are confident about the sender and the information within the email.
- You can hover the mouse over a link to reveal the destination address of the web site. A phishing email will have a different web site address from the legitimate one.
- Be vigilant when visiting social media sites and avoid clicking on links or advertisements.
At work, your IT department or IT provider will generally look after the security on your computer and network. You are less likely to have the same level of protection when you are outside of a corporate environment, therefore you have to make sure:
- You have an updated anti-virus program and run regular scans on your computer.
- Your computer has the latest security updates.
- Your wireless network is secure.
- Use strong passwords.
- Use different passwords for different usage types (e.g. Use one set of passwords for social media but a different set for banking).
