What is Phishing?

Phishing is a type of cyberattack in which attackers send fraudulent communications, or direct people to counterfeit websites in order to trick those individuals into revealing sensitive information, such as passwords, credit card numbers, or other personal data. Cybercriminals use this information for malicious purposes like identity theft, and financial fraud.

Types of phishing

The earliest phishing methods consisted of generalized attacks, casting a wide net in the hopes of aiming to trick the largest number of random people into divulging personal information. This lead to more specific attacks, with predetermined targets. The most common types of attacks include:

  • Spear Phishing: Targets specific individuals or organizations, often using personal information to make the attack more convincing.
  • Whaling: Targets high-profile individuals, like executives or celebrities, for valuable information.
  • Smishing: Phishing via SMS or text messages.
  • Vishing: Phishing over phone calls, where attackers impersonate legitimate entities to extract sensitive information.
  • Clone Phishing: Attackers replace legitimate links or attachments in a genuine communication with malicious ones.
  • Pharming: Redirects users to fake websites without their knowledge, even if they type the correct URL.
  • Business Email Compromise (BEC): Targets businesses, often involving compromising official email accounts to conduct fraudulent transactions.
  • Search Engine Phishing: Manipulates search results to lead users to malicious websites.
  • Malware-Based Phishing: Encourages users to download malicious attachments, leading to malware infection.
  • Ransomware Phishing: Tricks users into downloading ransomware that encrypts their data until the victim pays a ransom.
  • Credential Harvesting: Mimics legitimate login pages to steal usernames and passwords.

Combatting phishing

Combatting phishing requires a constantly evolving, multi-pronged approach. The most important step an organization can take to prevent successful phishing attacks is to implement security awareness training. Training staff to recognize the tell-tale signs of a phishing attack – such as suspicious email addresses, grammatical errors, and urgent requests for personal information – can dramatically reduce the likelihood of a successful attack. Many security awareness training programs include phishing simulations, which simulate real-life phishing emails to help staff identify them.

Organizations must also ensure that all staff use Multi-Factor Authentication (MFA) for all their accounts. MFA makes it difficult for attackers to gain unauthorized access through phishing. Even if the attacker obtains the login credentials, they would need that additional component of the login process only the legitimate user possesses.

Organizations may also consider implementing more technical means to deter phishing, such as Domain-based Message Authentication, Reporting, and Conformance (DMARC). DMARC solutions verify the authenticity of the sender’s domain and provide instructions on how email servers should handle messages that fail the authentication checks. DMARC allows domain owners to publish policies in their DNS records, which the receiving email servers then use to determine how to proceed with incoming emails from that domain.

The future of phishing

Phishing in the future will be defined by evolving tactics, innovative technologies, and the persistent exploitation of human psychology. As technology advances, phishing attacks are likely to become more sophisticated and adaptable, posing substantial challenges to cybersecurity techniques.

Emerging trends suggest that attackers will harness advanced automation and Artificial Intelligence (AI) to craft personalized and convincing messages on a massive scale. This could lead to an influx of targeted attacks, increasing the overall success rate.

Furthermore, the proliferation of Internet of Things (IoT) devices presents a potential avenue for exploitation, as attackers may exploit vulnerabilities in these devices to gain unauthorized access to networks and sensitive data.

The rise of voice assistants and deepfake technology could usher in a new era of voice-based phishing attacks, where malicious actors manipulate audio to create convincing impersonations.

Exploiting human psychology is expected to take center stage, with attackers focusing on emotional appeals, trust manipulation, and context-rich narratives to deceive recipients.
