Phishing vs Spear Phishing: Which One Is More Dangerous?

Phishing and spear phishing are two common cyber threats that rely on social engineering to trick individuals into providing sensitive information or performing specific actions, but are orchestrated to achieve different objectives. Although both types of attacks aim to deceive individuals, phishing attacks tend to rely on volume and impersonation tactics, while spear phishing attacks depend on personalization and reconnaissance.

Did you know:

• Phishing emails are opened by 30% of targeted individuals on average
• Spear phishing attacks are 9 times more likely to be successful than regular phishing attacks
• Even major companies like Google, Facebook, and Apple have fallen victim to spear phishing attacks in the past

In this article, we delve into the similarities and differences of phishing vs spear phishing attack techniques. We also learn the recommended practices to prevent such attacks and how a few simple awareness tips can prevent you from being a victim.

How Phishing Works

Phishing attacks are typically mass-distributed to a large number of individuals with the goal of obtaining sensitive information such as login credentials or financial information. These attacks are often carried out using a generic approach where the attacker creates a fake email or website impersonating a legitimate organization, and then sends it to a large number of individuals. The goal is to cast a wide net and see who falls for the scam.

Did you know that the most common type of phishing attack is the "invoice" or "payment" scam?

• Target Audience: Phishing attacks are more generalized and indiscriminate, typically involving many victims
• Language: Mostly use generic or impersonal language
• Attack detection: Attacks are often relatively unsophisticated and easy to detect
• Attack objective: Tricking individuals into giving away sensitive details, such as financial information or login credentials

Common Phishing Orchestrating Techniques

Attackers commonly use the following steps to orchestrate phishing attacks:

• Creating fake login pages that resemble legitimate websites to steal login credentials
• Using spoofed emails or domains, which appear to be from a legitimate source but are actually controlled by the attacker
• Sending regular phishing emails with attachments or malicious links that, when clicked, install malware or viruses on the recipient's device

How Spear Phishing Works

Unlike phishing attacks, spear phishing attacks are highly targeted and personalized, with the goal of tricking a specific individual or group into taking a specific action, such as transferring money or divulging sensitive information. The attacker usually has done research on the target and uses the information gathered to make the attack more convincing, increasing the likelihood of success.

Did you know that some spear phishing attacks can involve phone calls or in-person contact, known as "vishing" and "whaling" respectively?

Spear phishing attacks can be highly effective because they are customized to look like they are coming from a trusted source, such as a colleague or business partner.

• Target Audience: Spear phishing attacks are more personalized and targeted, usually directed at specific individuals or organizations.
• Language: Mostly use personal information (such as the victim's name, job title, or company name) to make the message appear more legitimate
• Attack detection: Highly sophisticated and harder to detect
• Attack objective: Gain access and steal sensitive data or to perform a specific action, such as wire transfers

Common Spear Phishing Orchestrating Techniques

Attackers commonly use the following steps to orchestrate phishing attacks:

• Using information from social media or other publicly available sources to personalize the attack and make it appear more legitimate
• Using a sense of trust or familiarity with the target, such as posing as a colleague or friend
• Using a sense of urgency or fear to convince the target to take immediate action, such as providing sensitive information or transferring money
• Using business email compromise (BEC) attacks, an attacker poses as a legitimate business or executive to trick employees into a wire transfer or providing other sensitive data

Phishing vs. Spear Phishing: Know the Differences and Similarities

Phishing and spear phishing are almost similar forms of cyber attacks that use deception to trick individuals into providing sensitive information or taking a specific action.

Similarities:

• Both types of attacks are orchestrated by sending fraudulent emails or messages that appear to be from a legitimate source (such as a bank or a well-known company)
• Use social engineering tactics to trick individuals into taking some action, such as clicking on a link, entering a password, or providing personal information
• Utilize email, text messages, websites, or phone calls as a medium to deliver the attack
• Have similar consequences, such as identity theft or financial loss
• Rely on the recipients' trust and can be challenging to detect

Differences:

• Phishing attacks are more generalized and indiscriminate, typically involving many victims. Spear phishing is a more personalized and targeted attack, usually directed at specific individuals or organizations.
• Phishing attacks often use generic or impersonal language. In contrast, a spear phishing email often uses personal information (such as the victim's name, job title, or company name) to make the message appear more legitimate.
• Phishing attacks often use general information and can be easy to detect. However, spear phishing attacks are more sophisticated and harder to detect.
• Regular phishing attacks are often used to gain access to general information, while spear phishing attacks are often used to gain access to sensitive information.

Phishing and Spear Phishing - Prevention and Protection

Prevention and protection against phishing and spear phishing can be achieved through a combination of technical and non-technical measures. Technical measures include the adoption of anti-phishing software, email filtering, two-factor authentication, and regular software updates. Non-technical measures include employee education, clear communication channels, strict policies and regular security reviews. In addition, it's essential to stay informed and aware of the changing threat landscape and attack patterns.

Phishing vs Spear Phishing - FAQs

Are There Any Common Signs or Red Flags to Look For in a Phishing or Spear Phishing Attempt?

Yes, there are several common signs and red flags to look for in a phishing or spear phishing attempt:

• Many emails contain spelling and grammar errors, which can be a red flag that the email is not legitimate.
• Be wary of emails from unfamiliar senders, especially if they ask for personal information.
• Be suspicious if you receive an email asking you to do something unusual or out of the ordinary, such as transferring money or providing sensitive information.
• Some phishers create fake web pages that mimic well-known companies' designs and logos. Be cautious and double-check when you receive an email from a company you have never heard of before.

Is It Possible to Completely Prevent Phishing and Spear Phishing Emails?

It is not possible to completely prevent phishing and spear phishing emails. These types of attacks are constantly evolving and can be challenging to detect. However, some measures can be taken to reduce the likelihood of successful attacks. These include educating employees about the risks and recognising a suspicious phishing email, implementing two-factor authentication, using anti-phishing software and implementing strict security protocols.

How Can Companies Use Deception Technology to Protect Themselves Against Phishing and Spear Phishing Attacks?

Companies can use deception technologies to protect themselves against phishing and spear phishing attacks by creating and deploying decoy assets, such as fake login pages or fake sensitive files, throughout their network. These decoy assets are designed to mimic tangible assets but are traps set up to detect and respond to suspicious activity.

For example, when a phisher or spear phisher attempts to access one of these decoy assets, the deception technology will trigger an alert, allowing the company to take action to mitigate the attack. In addition, companies can use deception technology to create phishing simulations to test the ability of their employees to protect them from malicious emails.

How Can Machine Learning Be Used to Detect and Prevent Phishing and Spear Phishing Attacks?

Machine learning can be used to detect and prevent phishing and spear phishing attacks in several ways:

• URL and attachment scanning: ML models can be trained to scan URLs and attachments in emails to identify suspicious URLs or attachments that contain malware.
• Anomaly detection: ML algorithms can detect and flag unusual behaviour, such as a spike in outgoing emails or a sudden change in login patterns, that could indicate a phishing or spear-phishing attack.
• Fraud detection: ML can detect and prevent phishing attacks by analyzing patterns in data, such as IP addresses, email headers, and website content, to identify a malicious link.
• Natural Language Processing (NLP): NLP can extract features from email text and header, such as sender's address, recipient, subject, and body text. ML models can be trained on this data to classify emails as phishing or non-phishing.

How Can Companies Use Network Segmentation to Protect Against Phishing and Spear Phishing Attacks?

Network segmentation is a security strategy that divides a network into smaller, more manageable segments, or subnets, to limit the spread of malware or unauthorized access in the event of security data breaches.

For example, companies can use network segmentation to protect against phishing and spear phishing attacks by isolating sensitive information, such as customer data or financial information, on a separate segment of the network that is not accessible from the rest of the network. Therefore, it will be difficult for hackers to access sensitive data or systems even if they can gain a foothold on the network.

How Do Phishing and Spear Phishing Attacks on Social Media Platforms Differ From Those via Email?

Here are some points of phishing and spear phishing attacks on social media platforms that differ from those via email.

• One key difference is that social media platforms tend to have publicly available information about their users, which hackers can use to craft more convincing spear phishing attempts.

For instance, an attacker may be able to find out an individual's name, interests, and friends and use that information to create a message that appears to come from a friend.

• Phishing attacks on social media platforms often use mobile devices. Many people access social media platforms via smartphone, making it harder to spot a phishing attack. In addition, social media platforms often have different security measures than email providers.

For example, social media platforms may have two-factor authentication or other security features not present in the email account. As a result, hackers may use different tactics to bypass these security measures.
