Forgery application attacks involve impersonating or manipulating legitimate entities to deceive users, enabling attackers to gain unauthorized access or control. These types of attacks exploit the trust that users or systems place in trusted sources.
The image illustrates "Forgery Application Attacks," showing a hooded figure at a computer with a skull and crossbones symbol, representing cyber threats. It explains that these attacks involve impersonating or manipulating entities to deceive users and gain unauthorized access.
To carry out these attacks, malicious actors create fake requests, messages, or signatures that seem to come from a trusted source. This deception can lead to unauthorized actions, data breaches, and significant security risks.
The image lists types of forgery application attacks: fake requests, fake messages, and fake signatures.
Understanding the various types of forgery attacks is crucial for effective cybersecurity. This article focuses on two prominent examples: Cross-Site Request Forgery (CSRF) and Email Spoofing.

​
Cross-Site Request Forgery (CSRF)

Cross-Site Request Forgery (CSRF) tricks a user into performing actions on a web application without their consent. Typically, the process involves the user authenticating on a website, after which the attacker leverages the active session to send unauthorized requests.
The image is an agenda slide with a gradient blue background on the left, listing two topics: "Cross-Site Request Forgery (CSRF)" and "Email spoofing."
The CSRF process generally unfolds in the following steps:
  1. The user logs into a web application and receives an authentication token or session cookie.
  2. The attacker crafts a malicious request that mimics a legitimate one.
  3. The attacker tricks the user into visiting a malicious website or clicking on a deceptive link.
  4. The web application executes the forged request using the user’s active authentication token, resulting in unauthorized actions.
The image is a diagram explaining the process of Cross-Site Request Forgery (CSRF), detailing four steps: User Authentication, Malicious Request, User Interaction, and Execution. Each step is represented with an icon and a brief description.
For example, consider a user logged into their banking application. An attacker might send an email containing a link to a malicious website. When the user clicks the link, a hidden form could automatically submit a request to transfer funds from the user’s account to the attacker’s account—all without the user’s awareness.
Ensure that web applications implement anti-CSRF tokens and verify the origin of HTTP requests to mitigate CSRF attacks.

​
Email Spoofing

Email spoofing involves forging email messages by using a fabricated sender address to deceive recipients. In this attack, the attacker impersonates a trusted entity to manipulate the recipient into taking harmful actions, such as revealing sensitive information or installing malware. The email spoofing process typically includes:
  1. Crafting an email that appears to be sent from a trusted source, such as a bank or colleague.
  2. Manipulating the email headers to include a forged sender address.
  3. Deceiving the recipient into believing the email is genuine, prompting them to follow instructions that may lead to data theft or malware infection.
The image illustrates the process of email spoofing, detailing three steps: email creation, forging the sender address, and deception.
For instance, an attacker might send an email that seems to originate from the recipient’s bank requesting account verification. When the recipient clicks on the provided link, they are directed to a fraudulent website designed to harvest their login credentials.
Always exercise caution when receiving unexpected emails, especially those requesting sensitive information or urging immediate action. Verify the sender’s authenticity via trusted channels before complying.

Conclusion

Forgery application attacks, including CSRF and email spoofing, represent significant security risks. By comprehending these attack methods, organizations and individuals can implement stronger safeguards to protect sensitive data and prevent unauthorized actions.
The image is a slide with a gradient background titled "Conclusion," highlighting the security risks of forgery application attacks and the importance of understanding CSRF and email spoofing.
