What is Spear Phishing?

We all have heard about phishing, but did you know that there are different types of phishing? One prevalent form is spear phishing. 

Spear phishing is the fraudulent practice of tricking users into providing confidential personal or financial information. Attackers do this to accomplish their ultimate goal of gaining access to internal systems or extracting funds from the enterprise. They can also sell these details to buyers who’d like to infiltrate your system.

Spear phishing is highly targeted, making it the most dangerous type of phishing attack. According to Verizon’s 2020 Data Breach Investigation Report, spear phishing is involved in 22% of data breaches, more than any other threat action type. 

Unlike phishing attacks that send emails to multiple recipients, such as what Netflix experienced, spear phishing emails are designed to target specific individuals. Typically, spear phishing emails prey on lower-ranked individuals within an organization, whereas a whale phishing email is sent to managers and executives.

How Spear Phishing Happens

Typically, there are 5 steps behind a successful spear phishing operation: target acquisition, weaponization, grooming & delivery, information capture, and execution. Here are some things that happen in each stage: 

Stage 1: Target Acquisition

During this stage, the attacker gathers intelligence on the target, such as personnel and technological information.

Stage 2: Weaponization

The attacker selects the most vulnerable channel and best method of entry into the organization.

Stage 3: Grooming and Delivery

This is where the attacker creates the “story” for the attack. This involves designing the message, writing the cover text, establishing the link, and so on.

Stage 4: Information Capture

Here, the attacker logs the information gathered during the attack. He then attempts to log in using the target’s credentials.

Stage 5: Execution

With access to the user’s accounts, the attackers can now steal money, information, or even sell the log-in credentials to third parties.

How to Protect Your Business Against Spear Phishing Attacks

You can still fight against these cyber threats. There are many ways to protect yourself and your business against spear phishing: 

Check and Verify 

Beyond spelling or grammatical errors, any suspicious requests asking for your personal information is a red flag of a phishing attempt. Even if this kind of request is made from your “CEO,” it is best to directly ask the individual to ensure they were the sender.

Analyze the Links

Hover over the hyperlinks in the email to view a preview of the links to ensure they are coming from legitimate and safe sources.

Protect Your Password

Keep your password information private and change it often to decrease the chances of your account being compromised via a password spray.

Let the Whole Team On It

Teach your employees how to detect these attacks. The better educated your team is about this type of phishing attack, the better prepared they will be to fight it. 

Invest in Quality Email Security Solution

While much of spear phishing can be detected by trained eyes, employees cannot or simply do not have the time to check all emails carefully. This can lead to dire consequences that impact the business. Investing in a security solution with comprehensive threat detection is essential to running a business in 2022 and beyond.
