What is Phishing?
A phishing attack is a form of social engineering attack in which the attacker sends a malicious message to the intended recipient. This message may use trickery, coercion, or psychological manipulation to get the recipient to perform some action. Often, this includes clicking on a malicious link or opening an infected attachment; however, some attacks — like business email compromise (BEC) attacks — use no malicious content and solely attempt to get the user to perform an action — such as paying a fake invoice.
Phishing attacks come in a variety of different forms, including:
- Email Phishing: Email is the most well-known medium for phishing attacks. Its prevalence as a corporate communications tool and the ability to embed links and attachments makes it an ideal vector for phishing attacks.
- Text Phishing: As mobile devices are more commonly used for business, attackers have increased their use of SMS messages for phishing attacks (called smishing). Users are accustomed to quickly reading texts, and the use of link-shortening services in SMS is ubiquitous, making it easier to conceal malicious links.
- Voice Phishing: Voice phishing or “vishing” attacks use phone calls rather than written messages to deliver phishing content. Vishers try to talk the target into handing over sensitive information or installing malware on their own computer.
- Platform Phishing: Social media apps and corporate collaboration platforms often have the ability to send private messages and include attachments. These platforms can also be used for phishing attacks.
Phishing is one of the most common cyberattacks and is often used to gain initial access to enable other attacks. Anyone can be the target of a phishing attack in both their corporate and private lives.
What is Spear Phishing?
Spear phishing is a particular type of phishing attack that targets a specific individual or group. These attacks are designed to have a higher success rate than more general phishing attacks since they are more personalized and draw on realistic details.
Spear phishing attacks use many of the same techniques as general phishing ones but are based on more research and planning. The attacker will investigate their intended target and select a pretext that the victim is likely to believe. These phishing messages may also be made more plausible using spoofed email addresses, dynamic URLs, and similar techniques.
Like other phishing attacks, spear phishing emails are designed to steal data or act as a first step in a cyberattack. The phishing email may carry invoices targeted to the individual or organization, suggest that a password change is needed for a corporate application, or carry malware customized to the organization’s environment and systems.
The Difference Between Spear Phishing and Phishing Attacks
Phishing and spear phishing attacks both use the same general tools and techniques. Both use trickery or psychological manipulation to induce the recipient to perform some action. They can both use various media — email, SMS, etc. — as well.
The main difference between phishing and spear phishing is the level of personalization and research involved in the attack. General phishing emails are part of mass campaigns in which the pretext is designed to appeal to as many potential targets as possible. These emails have a low success rate but can make up for this in volume.
Spear phishing, on the other hand, uses a more targeted, personalized pretext. This increases the probability of success but has a smaller pool of potential targets. These attacks may be performed by more sophisticated attackers or be used by nation-states to advance their goals or target certain organizations.
