Verizon's Data Breach Investigative Reports states email phishing is the number one cause of data breaches and 43% of cyberattacks are targeted at small to medium-sized businesses (SMB.) The frequency of attacks is on the rise and huge losses are being realized throughout all types of organizations. Here is a look at the different types of phishing emails that are common in the workplace, how they can be used in a cyberattack, and the cybersecurity best practices to reduce your risk.
What's the difference between spam, phishing, and spear-phishing emails?
- Spam: These are unsolicited emails typically trying to sell you something legitimate, or not, and may contain ransomware or malware hyperlinks. Mostly these are considered an annoyance.
- Phishing: Is targeted at a wide range of recipients ("Click Here to Get Free Pizza") specifically crafted to get you to click, to get your login credentials, or to deliver a malware payload.
- Spear-phishing: Has the same criminal objective of a phishing email, however, it is specifically designed to get your attention. The email may look as if it came from someone you know or an organization you do business with. It might contain information that you believe only you and your friends would know about; like the vacation you took to Aruba where you uploaded your photos to Facebook. The criminal’s goal is to have you drop your guard and respond.
Another type of email attack to be aware of is Business Email Compromise (BEC), also known as whaling attack. This attack happens when a cybercriminal spoofs a business leader's email account to send legitimate appearing emails to staff or business partners. These highly-targeted, sophisticated emails are meant to trick the recipient into thinking it's coming from a trusted source. The cybercriminals goal is usually financial. For example, they will send a request to the finance department to make an urgent payment. They are also use whaling attacks to send malware in the hopes of getting to your sensitive data and systems.
