  • Spear phishing
  • Business email compromise (BEC)

Usually, phishing attempts are the first step in a bigger plan of attack. These emails typically bait recipients to visit a fake webpage, prompting them to log in with their company’s credentials. Some examples of these emails include links to files allegedly hosted on Google Drive, a request for verification of a PayPal transaction, or an invitation to a Microsoft Teams session. In some cases, the email would also direct recipients to purchase merchandise from a fake website.

2. Account takeover

As the name suggests, this technique is used by criminals to hack and impersonate the compromised account user in order to steal sensitive and valuable information and data, or to intercept private communications. Similarly, an account takeover may also be just the first stage of attack in a larger scheme.

You might think that these only happen in movies. However, many have already fallen victim. A real-life example unravelled by Check Point earlier this year revealed the scheme of a sophisticated cybercrime gang dubbed the Florentine Banker Group. These criminals manipulated emails, registered lookalike domains, and created man-in-the-middle attacks to heist wire transfers amounting to US$1.3m from three British private equity firms.
