What Is Phishing?

Phishing is a form of cyberattack where attackers employ deceptive techniques to trick individuals into divulging sensitive information, such as passwords, credit card numbers, or personal details. It typically involves the use of fraudulent emails, text messages, or websites that masquerade as legitimate and trustworthy entities, such as banks, social media platforms, or online retailers.

The primary objective of phishing is to manipulate victims into unknowingly providing their confidential information or performing actions that benefit the attackers. These actions can include clicking on malicious links, downloading malware-infected attachments, or entering personal data on fake login pages.

History Of Phishing

During the 1990s, early instances of phishing were attributed to black hat hackers and the warez community who exploited AOL to engage in online criminal activities, such as stealing credit card information. The term “phishing” is believed to have been coined by Khan C. Smith, a notorious spammer and hacker. 

Its first documented mention was discovered in the hacking tool called AOHell, which was made available in 1995. AOHell provided hackers with the ability to pose as AOL staff and send instant messages to victims, requesting them to disclose their passwords. In response to these threats, AOL implemented various measures to combat phishing and eventually took action to shut down the warez scene on their platform.

Phishing attacks have become more frequent, with the number of reported incidents increasing exponentially since the early 2000s. Today, phishing has become increasingly sophisticated and widespread, with cybercriminals constantly adapting their tactics to exploit new technologies and target unsuspecting users.


Target Victims Of Phishing

In the corporate landscape, no employee is immune to the risk posed by skilled scammers. Position or seniority does not provide protection. Scammers effortlessly gather information from company websites and social media, including email addresses, hierarchies, and ongoing projects. With this knowledge, they exploit personal details like names, job responsibilities, and colleagues’ information, luring individuals into spear-phishing traps. 

The consequences of such breaches can grant unauthorized access to critical company systems. Even high-ranking executives are not immune to these threats. In fact, their public visibility and extensive online presence often make them more susceptible targets. The widespread availability of their personal information further exacerbates the risk they face.1


Types Of Phishing Attacks

Let’s take a comprehensive look at some of the most common phishing attacks.


Business Email Compromise

Business email compromise (BEC) refers to a form of cybercrime wherein scammers employ email as a means to deceive individuals into disclosing confidential company information,  sending money, or as simple as clicking on a link or opening an attachment which then gives the criminals an entrance into the company . The perpetrator assumes the identity of a trusted individual, often posing as a high-ranking executive or a known business partner.2

The attacker will send an email to an employee, pretending to be the executive, requesting a transfer of funds or sensitive data. The email often appears to be from a legitimate source and may contain details about the company or the executive.

Clone Phishing

Clone phishing is a specific type of phishing attack where the attacker meticulously duplicates the design, content, and structure of a legitimate email to deceive victims into disclosing confidential information or credentials. The malicious actor sends an email or directs the victim to a website that appears identical to the genuine one but is, in fact, a cloned version. 

This cloned website or email is skillfully crafted to replicate the original, often including logos, branding, and other elements to create a convincing illusion of authenticity. Within the cloned content, there are typically links that lead to the attacker’s own website, which is designed to collect the victim’s sensitive data. 


Angler Phishing

Angler phishing is a specific variant of phishing attack that specifically targets social media users. In this type of attack, a hacker deliberately creates a counterfeit social media account, assuming the role of a customer service representative or employee from a particular company. The attacker’s primary objective is to exploit individuals who have previously voiced complaints or concerns about the company on social media platforms.3

Using this fabricated persona, the hacker initiates contact with these targeted customers, aiming to gain their trust. Through various deceptive tactics and social engineering techniques, the attacker manipulates the victims into divulging sensitive or private information. This can include personally identifiable information (PII), login credentials, or financial details.


Domain Spoofing

Domain spoofing, or DNS spoofing, is a technique employed by hackers to mimic the domain of a legitimate company or organization,  to deceive users into thinking they are accessing a legitimate website. 

By impersonating a reputable entity, the attacker aims to deceive recipients into believing the communication is legitimate. They may request sensitive information, such as login credentials, financial data, or personal details, under the guise of the spoofed domain. 

Spoofed domains can be incredibly deceptive, as they often closely mimic the genuine domain name by cleverly incorporating special characters. This makes it challenging to distinguish between the authentic and the counterfeit.


Importance Of Phishing Detection

Phishing detection plays a crucial role in safeguarding both organizations and individuals against cyber threats. Here are some key points highlighting the importance of phishing detection:

  • Protecting sensitive data: Effective phishing detection measures help identify suspicious emails, websites, or messages that attempt to gather such data, enabling organizations and individuals to protect their sensitive information.
  • Preventing financial losses: Effective phishing detection measures can stop unauthorized access, fraudulent transactions, and unauthorized transfers, preventing significant financial losses for organizations and individuals.
  • Safeguarding reputation: Detecting and responding to phishing attacks promptly protects an organization’s brand image, customer trust, and individuals’ personal reputation from being associated with cybercrime.
  • Mitigating malware and ransomware risks: Phishing attacks often serve as a gateway for delivering malicious software. Detection helps identify and block phishing attempts, reducing the risk of malware infections and ransomware attacks.
  • Ensuring regulatory compliance: Implementing strong phishing detection measures helps organizations meet data protection and privacy regulations, avoiding penalties and legal issues associated with data breaches caused by phishing attacks.


Phishing Detection Methods

Phishing detection methods are designed to identify and mitigate targeted email attacks, bolstering a cybersecurity strategy. Here are some phishing detection methods.


Heuristic Analysis And Machine Learning

Given the increasing quantity and sophistication of web attacks on the internet heuristic-based techniques, coupled with machine learning, have become vital in artificial intelligence. They can be employed in situations where traditional algorithms are not readily available or applicable. 

The heuristic-based detection technique specifically focuses on analyzing and extracting features from phishing sites to identify and detect them effectively. By leveraging the power of heuristics and machine learning, this approach enhances the detection capabilities in combating the growing threat of phishing attacks in diverse web service environments.4


URL Filtering

URL filtering is also employed as a phishing detection method to combat phishing attacks. Phishing URLs are often designed to mimic legitimate websites, tricking users into providing sensitive information. Through URL filtering implementation, organizations can maintain a database of known phishing URLs and block access to such malicious websites.

When a user clicks on a link or enters a suspicious URL, the filtering system compares it against the database of known phishing URLs and alerts or blocks the user from accessing the site. This method helps prevent employees from falling victim to phishing attacks by proactively identifying and blocking potentially harmful URLs.


Black And White List

Whitelisting and blacklisting are two distinct methodologies used to control access to various resources, such as websites, email, software, and IP addresses within networks. Whitelisting operates on the principle of denying access to all resources by default, except for those explicitly approved or “whitelisted” by the owner or administrator.

Only specifically identified items or individuals are granted access, while everything else is automatically blocked. This approach provides a high level of control and security as it ensures that only trusted entities are permitted to access the designated resources.

Blacklisting functions by allowing access to all resources unless they are explicitly prohibited or “blacklisted” by the owner or administrator. In this approach, the owner creates a list of known threats, malicious entities, or restricted items, and blocks access to them while permitting access to everything else.


Attack Topologies-Based Phishing Detection

Attack topologies-based phishing detection is a method of identifying and mitigating phishing attacks by analyzing the underlying structure and characteristics of phishing campaigns. Instead of relying solely on specific indicators or signatures of known phishing emails, this approach focuses on understanding the tactics, techniques, and procedures (TTPs) employed by attackers to orchestrate phishing attacks.



In a compromise-based phishing scenario, a malicious actor gains unauthorized access to a legitimate website and stealthily injects a phishing page into the website’s structure without the knowledge or consent of the website owner. This type of attack takes advantage of the trust users place in familiar websites by redirecting them to a fraudulent page that mimics the legitimate site’s appearance. 

Since the phishing page resides within the compromised website, it can be challenging to detect by traditional security measures, making it crucial to employ comprehensive security practices and detection techniques to identify and mitigate such compromise-based phishing attacks.



This detection method aims to identify and prevent phishing attacks by analyzing and scrutinizing the domain names associated with suspicious emails, websites, or other forms of digital communication.

Domain-based phishing detection utilizes various methods, such as domain reputation analysis, domain name similarity checks, and domain blacklisting to assess the legitimacy and trustworthiness of domains. 

By comparing the domain names of incoming emails or URLs with known legitimate sources or identifying characteristics of phishing attempts, this approach helps identify potential phishing threats and safeguard users from falling victim to these fraudulent schemes. 


Between Phishing Detection Vs. Response Software

Phishing detection and response software consist of two interconnected components that work together to protect organizations from phishing attacks. Phishing detection tools can help in identifying and flagging potential phishing threats by analyzing various indicators such as email content, sender information, and embedded links to differentiate between legitimate and malicious emails. 

On the other hand, phishing response software is designed to facilitate prompt and effective actions once a phishing attack is detected. It provides automated incident response workflows, enabling organizations to quickly quarantine or flag suspicious emails, alert administrators, and initiate remediation processes. 


Website Phishing Vs Email

Website phishing and email phishing are two common methods used by attackers to deceive individuals and steal sensitive information. Website phishing involves creating fraudulent websites that mimic legitimate ones, tricking users into entering their personal information or login credentials. These deceptive websites often have URLs and designs similar to the genuine sites they imitate, making it difficult for users to discern the difference.

Email phishing involves sending deceptive emails that appear to be from trusted sources, such as banks, social media platforms, or reputable organizations. These emails typically contain malicious links or attachments that, when clicked or opened, direct users to fake websites or download malware onto their devices. 


Email Security Suite Vs. Point Solution

Email security suites are comprehensive solutions that protect against a range of threats, including phishing. They provide a wide range of features, such as spam filtering, virus scanning, and content control. Many also include data loss prevention (DLP) capabilities, which can help protect against data breaches.

Point solutions, on the other hand, are designed to protect against a single type of threat, such as phishing. They are typically more focused and offer fewer features than security suites. Point solutions are often more affordable than suites, but they may not provide the same level of protection.


Prevention Vs. Detection

Phishing prevention focuses on implementing proactive measures to reduce the likelihood of successful phishing attempts. This includes educating users about phishing techniques, promoting strong security practices such as using unique and complex passwords, enabling multi-factor authentication, and implementing email and web filtering to block known malicious sources.

Detection focuses on identifying and flagging potential phishing attacks that have circumvented preventive measures. Detection mechanisms could involve advanced algorithms and analysis of email content, URLs, and user behavior to identify suspicious patterns or indicators of phishing. Detection solutions provide real-time monitoring and alerts to security teams, allowing them to respond quickly and mitigate the impact of an ongoing phishing attack.
