Phishing

Phishing is the fraudulent attempt to obtain sensitive information such as usernames, passwords and credit card details by disguising oneself as a trustworthy entity in an electronic communication. Typically carried out by email spoofing or instant messaging, it often directs users to enter personal information at a fake website which matches the look and feel of the legitimate site. The first phishing lawsuit was filed in 2004 against a Californian teenager who created the imitation of the website “America Online”. With this fake website, he was able to gain sensitive information from users and access the credit card details to withdraw money from their accounts. Other than email and website phishing, there’s also ‘vishing’ (voice phishing), ‘smishing’ (SMS Phishing) and several other phishing techniques cybercriminals are constantly coming up with.

Phishing is an example of social engineering techniques being used to deceive users. Users are often lured by communications purporting to be from trusted parties such as social web sites, auction sites, banks, online payment processors or IT administrators. Attempts to deal with phishing incidents include legislation, user training, public awareness, and technical security measures, the latter being due to phishing attacks frequently exploiting weaknesses in current web security. The word itself is a neologism created as a homophone of fishing.

Attributes of Phishing include:

  • Catchy: Lucrative offers and eye-catching or attention-grabbing statements are designed to attract people’s attention immediately. For instance, many claim that you have won an iPhone, a lottery, or some other lavish prize. It’s okay to like free stuff but being a little more careful would not hurt.
  • Sense of Urgency; a favorite tactic amongst cybercriminals is to ask you to act fast because the super deals are only for a limited time. Some of them will even tell you that you have only a few minutes to respond. When you come across these kinds of emails, it’s best to just ignore them. Sometimes, they will tell you that your account will be suspended unless you update your personal details immediately. Most reliable organizations give ample time before they terminate an account and they never ask patrons to update personal details over the Internet. When in doubt, visit the source directly rather than clicking a link in an email.
  • Hyperlinks: a link may not be all it appears to be. Hovering over a link shows you the actual URL where you will be directed upon clicking on it. It could be completely different or it could be a popular website with a misspelling, for instance www.bankofarnerica.com. Some letters differ from the original website’s.
  • Attachments; If you see an attachment in an email you weren’t expecting or that doesn’t make sense, it’s bestTbest to avoid and delete such messages because they could contain payloads like ransomware or other viruses. The only file type that is always safe to click on is a .txt file.

A few ways to avoid Phishing attacks are:

  • Spam filters: To protect against spam mails, spam filters can be used. Generally, the filters assess the origin of the message, the software used to send the message, and the appearance of the message to determine if it’s spam. Occasionally, spam filters may even block emails from legitimate sources, so it isn’t always 100% accurate.
  • Browser settings: The browser settings should be changed to prevent fraudulent websites from opening. Browsers keep a list of fake websites and when you try to access the website, the address is blocked or an alert message is shown. The settings of the browser should only allow reliable websites to open up. Many websites require users to enter login information while the user image is displayed. This type of system may be open to security attacks. One way to ensure security is to change passwords on a regular basis, and never use the same password for multiple accounts. It’s also a good idea for websites to use a CAPTCHA system for added security.
  • Banks and financial organizations use monitoring systems to prevent phishing. Individuals can report phishing to industry groups where legal actions can be taken against these fraudulent websites. Organisations should provide security awareness training to employees to recognise the risks.

Generally, emails sent by cybercriminals are masked so they appear to be sent by a business whose services are used by the recipient. A bank will not ask for personal information via email or suspend your account if you do not update your personal details within a certain period of time. Most banks and financial institutions also usually provide an account number or other personal details within the email, which ensures it’s coming from a reliable source. Also, we’d all agree that getting “free iPhones” or gadgets in general cannot be true and should be tagged as spam. As such, let’s endeavour to avoid such situations.
