How Not To Get Hooked By Phishing

Phishing is a form of social engineering where cyber criminals will attempt to steal sensitive data such as usernames, passwords or credit card details. Often they are especially interested in you giving them access to your computer unwittingly. This enables them to steal your data at their leisure. They achieve this by disguising themselves as a trustworthy party in an email, on social media, text messages or by phone. Phishing attacks can be highly sophisticated encouraging the user to open a malicious file or link. This can result in either Malware being downloaded to a digital device or being sent to a spoofed website that collects sensitive data. From this the attacker can extract the data required to execute a successful attack.

Phishing can have devastating consequences such as reputational damage, loss of custom, loss of money, business disruption and data breaches. These threats are on the rise because they can be extremely profitable.

How Can The Cyber Criminals Get You Hooked?

Did you know 91% of all data breaches start with some form of Phishing attack?*

There are a few Phishing techniques cyber criminals can use to convince you to take the bait. For the moment let’s focus on the classic campaigns used.

Email Phishing Scams

Phishing is a game of numbers. A cyber criminal will send a batch of thousands of fraudulent emails that mimic those sent by genuine organisations. An attack may happen in the following way:

  1. The hacker will send an email from a seemingly legitimate source such as PayPal or Netflix
  2. The email will create a sense of urgency such as your account has been compromised
  3. A link will offer you the chance to update your password or sensitive data
  4. The hacker is then able to collect your data or gain access to your computer, acquiring more account details and access to resources

Email Phishing

Spear Phishing

Spear Phishing is an attack where the cyber criminal targets a specific person or organisation instead of trying his luck with multiple fraudulent emails. For this version of phishing to work the attacker requires in depth information on your organisation and its hierarchy. An attack may happen in the following way:

  1. The hacker will identify and research a potential victim or organisation
  2. The hacker will send a targeted email to the victim that seems to be from a legitimate source such as a trusted colleague
  3. The victim will open the fake email that contains either a malicious attachment or link asking for the user to provide sensitive data
  4. A back door is then created, or malware deployed allowing access to your computer or sensitive data being collected and transferred to the attacker
