Concept
Phishing
Summary
Phishing is a form of social engineering and scam where attackers deceive people into revealing sensitive information or installing malware such as ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim is navigating the site, and transverse any additional security boundaries with the victim. As of 2020, it is the most common type of cybercrime, with the FBI's Internet Crime Complaint Center reporting more incidents of phishing than any other type of computer crime.
The term "phishing" was first recorded in 1995 in the cracking toolkit AOHell, but may have been used earlier in the hacker magazine 2600. It is a variation of fishing and refers to the use of lures to "fish" for sensitive information.
Measures to prevent or reduce the impact of phishing attacks include legislation, user education, public awareness, and technical security measures. The importance of phishing awareness has increased in both personal and professional settings, with phishing attacks among businesses rising from 72% to 86% from 2017 to 2020.
Phishing attacks, often delivered via email spam, attempt to trick individuals into giving away sensitive information or login credentials. Most attacks are "bulk attacks" that are not targeted and are instead sent in bulk to a wide audience. The goal of the attacker can vary, with common targets including financial institutions, email and cloud productivity providers, and streaming services. The stolen information or access may be used to steal money, install malware, or spear phish others within the target organization. Compromised streaming service accounts may also be sold on darknet markets.
This type of social engineering attack can involve sending fraud emails or messages that appear to be from a trusted source, such as a bank or government agency. These messages typically redirect to a fake login page where the user is prompted to enter their login credentials.
