October 2008 - Volume 3, Issue 10 - Phishing – How to Avoid Getting Hooked!
October is National Cyber Security Awareness Month!
The Fifth Annual National Cyber Security Awareness Month is being celebrated during October 2008 as a collective effort among the Multi-State Information Sharing and Analysis Center, the National Cyber Security Division and the National Cyber Security Alliance to raise cyber security awareness nationwide and empower citizens, businesses, government and schools to improve their cyber security preparedness and help promote a safe Internet experience.
What is Phishing?
is a scam which attempts to entice email recipients into clicking on a link that takes them to a bogus website. The website may prompt the recipient to provide personal information such as social security number, bank account number or credit card number, and/or it may download malicious software onto the recipient’s computer. Both the link and website may appear authentic, however they are not legitimate.
How does it Work?
Have you received an email, an instant message, or another communication that just did not seem right, even though the communication appeared to be from a reputable organization? This communication could very well be a phishing scam. It’s important to note that in the past, phishing scams were often more easily detectable because of misspellings, typographical errors and blatantly bad grammar; however, they are increasingly more difficult to detect because they often appear so legitimate.
Phishing scams try to “bait” the recipient in a number of ways: the malicious email could include notice of an account cancellation, a request to verify/update personal information, a notice of a purchase that you did not make, or just about anything else that would get you to respond to the communication. The types of messages used in phishing are expanding almost every day, so it is important to be cautious of any communications you receive.
If the email communication, with its enticing subject line, is the “bait,” what is the hook? The hook is getting you, the user, to take some action that enables the phisher to obtain information or otherwise gain access. You may be “tricked” into visiting a website, which appears to be a legitimate organization’s website. Once at that site, you may be asked to enter personal information. Another method of attack may be to get you to open an attachment in an email, upon which malicious code, such as a Trojan horse will be installed onto your computer. Other variations include a telephone call, in which the phisher will ask you to provide personal information. Once the phisher has “hooked” you, they may use the information to open accounts in your name, access your bank account or make purchases using your credit card. There is also a type of phishing attack known as “spear phishing” where the attacker targets specific individuals by name or organizations. For example, an email invitation to attend an event that may be of interest could be sent to an organization’s employees. When an employee clicks on the link contained in that email, malware is downloaded to the employee’s computer. The attacker may be targeting specific employee information, such as user names and passwords, or proprietary organization information.
How do I Know it is a Phishing Scam?
- If you receive an email appearing to be from a legitimate business, requesting you submit personal information, it is most likely a scam. Legitimate businesses do not send emails requesting personal information.
- Use an Internet search engine to research the subject line of a suspicious email to determine if that subject line is a known phishing scam.
What Can I Do?
- Be cautious about all communications you receive. Think before you click.
- If the communication looks too good to be true, it probably is.
- If it appears to be a phishing communication, do not respond. Delete it. You can also forward it to the Federal Trade Commission
- Do not click on any links listed in the email message and do not open any attachments contained in suspicious email.
- Do not enter personal information in a pop-up screen. Legitimate companies, agencies and organizations don’t ask for personal information via pop-up screens.
- Install a phishing filter on your email application and also on your web browser. These filters will not keep out all phishing messages, but will reduce the numbers of phishing attempts.
- Ensure that your computer is up-to-date on all patches.
- Ensure that your antivirus program is installed and up-to-date.
- Use bookmarks in your web browser for the organization’s which with you regularly communicate to limit the chances of being redirected to malicious sites.
- If you think you have been scammed, visit the Federal Trade Commission
- Look for unauthorized charges or withdrawals on your credit card and bank statements/bills.
- Review your credit report - visit the Federal Trade Commission for a link to request an annual free credit report.
