Spear Phishing: A Common and Costly Threat to All Organizations

Spear phishing is currently one of the most serious threats to businesses of all sizes across all industries. Preventing successful spear phishing attacks should be a principal concern for all company owners and managers. Spear phishing, or the act of sending fraudulent emails that appear to be from a known or trusted sender in order to obtain sensitive information, is becoming increasingly common and can have disastrous implications for businesses due to the potential reward for a successful attack and the ease of which it can be implemented.

 Spear phishing can be viewed as a cyber crime double-play. Attackers have the ability to compromise the identity of one business and then use it to steal the personal information of another.  

Cyber attacks know no boundaries in today’s world. Hackers may want your login credentials to access bank accounts or protected files. They may go after social security numbers, leaving your employees and clients vulnerable to individual attack. They seek out many types of confidential information that can be used or sold, which can be obtained through deceptive spear phishing emails that utilize advanced social engineering tactics.

Businesses have a lot to lose in this unfair and malicious game. Currently, over 95% of all attacks on enterprise networks are the result of successful spear phishing (SANS Institute). Spear phishing is frequently a preliminary attack vector in data breaches and data theft, which have the potential to drain bank accounts and destroy reputations.

How to Recognize a Spear Phishing Email:

Although spear phishing campaigns utilize advanced social engineering technology to deceive recipients and gain access to confidential information, there are various best practices that email users should implement which will increase their chances of recognizing these malicious emails:

  • Verify shared links to ensure that they do not lead to fraudulent websites or malicious code.
  • Scan all attachments for viruses or dangerous code.
  • If an email looks suspicious in any way, make a phone call to the sender to confirm the legitimacy of the email.
  • Check for spelling and grammatical errors which can indicate that an email is not authentic. Also, keep an eye out for suspicious subject lines and signatures.
  • Think about each email you receive before clicking on links or downloading attachments. For example, ask yourself: Does an order confirmation email you’ve received correspond to a recent purchase you have made? Do the sender and recipient addresses make sense?

The image to the right is a spear phishing email which was identified and quarantined by Guardian Digital EnGarde Cloud Email Security. It mimics a legitimate FedEx shipment confirmation email very closely, and is an especially dangerous email for this reason. Some indications that this is a fraudulent email include: 

  1. An invalid “From” email address
  2. Invalid tracking information which differs in the subject and in the body of the email
  3. A malicious attachment in the bottom left corner - FedEx does not send tracking information in the form of an attachment

These are spear phishing “red flags” that many people are not aware of, which is why investing in an advanced cloud email security is imperative to effective email protection.
