Phishing is one of the most common attack vectors hackers use to initially infiltrate a user’s system. Phishing is an attempt to obtain user credentials, financial data, or other sensitive information by emulating a legitimate email communication. Phishing emails can also be used to trick a user into clicking on a malicious attachment or link that is embedded into an email. Spear phishing, on the other hand, is a targeted phishing campaign where hackers first research their target individual or company to increase their chance of success. By doing this, hackers attempt to appear more trustworthy as a legitimate business entity thus making the target less suspicious. Spear phishing presents a much greater threat than phishing in general as the targets are often high-level executives of large corporations.
