‘Insider spoofing’ or faking the CEO’s email address to trick the CFO into transferring millions to criminal bank accounts is big business. 

According to the FBI, between October 2013 and August 2015, 7,066 US businesses have fallen prey to ‘business email compromise’, netting criminals an estimated $747m.

Non-US victims lost a further $51m over the period, with the FBI estimating a 270 percent increase in identified victims since January 2015, when it first released figures about the threat category.

How to Prevent Hacking.
1. You need to make sure your personal computer does not have viruses, trojans, keyloggers, etc.
2. Change your passwords often. Use a different password for each website you regularly log into, and make sure your passwords are long and intricate so that they’re harder to guess. It’s especially important to keep your banking and other financial accounts secure.
3. Delete emails from unknown sources. Never click on an emailed link that looks questionable.
4. Do not respond to pop-up windows.
5. Do not download from unknown sites or free printables, desktop wallpapers, music-streaming software. It’s a quick and easy way for hackers to infiltrate you system.
6. Do not install illegal copy or any free program.
