10 Most clicked phishing email subject lines

Phishing email messages, websites, and phone calls are designed to steal money. Cyber criminals can do this by installing malicious software on your computer or stealing personal information off of your computer.

Cyber criminals also use social engineering to convince you to install malicious software or hand over your personal information under false pretenses. They might email you, call you on the phone, or convince you to download something off of a website.

According to Verizon’s 2017 Data Breach Investigations Report, two-thirds of all malware was installed via email attachments in 2016. 60% of malware was packaged in JavaScript attachments. With a lot of people still not fully aware of the risks posed by these emails, the number of successful exploits is on the rise.
