What is formjacking, and how to prevent it?
tl;dr: Formjacking is a cyber-attack where hackers inject malicious code into online forms to steal sensitive information, such as credit card details. It poses significant risks to individuals and businesses alike.
In the ever-evolving landscape of cyber threats, one menacing tactic has gained prominence in recent years – formjacking. This insidious method of cyber attack involves the injection of malicious code into online forms on websites, enabling cybercriminals to steal sensitive information entered by unsuspecting users. This article delves into formjacking, how it works, the risks of formjacking, and how to prevent it.
Understanding Formjacking
Formjacking is a cyber attack wherein hackers compromise a website’s security to inject malicious code into its online forms. These forms can include anything from login credentials and personal information to payment details during an online purchase. The injected code discreetly captures and transmits this sensitive data to a server controlled by the attackers.
As the user inputs financial details on the website’s payment page, the data isn’t solely transmitted to the intended website but is also sent to the malicious code injector, the attacker. The user might be unaware of the situation, mistakenly believing their information is directed to the website rather than being transmitted to the attacker.
Formjacking is typically employed to acquire credit card details, prompting hackers to focus on websites featuring payment pages, such as those on e-commerce platforms. Additionally, hackers also gather users’ details. This acquired information may be utilized for direct monetary theft by hackers or sold to others in exchange for payment.
How It Works
Cybercriminals exploit a website’s security vulnerabilities to inject malicious code into the form submission process.
This injected code captures the data entered into the form by users, sending it to a server controlled by the attacker.
The cybercriminals target the actual form page, and with each form submission, a replica of the entered information is forwarded to the attacker.
Unlike other cyber threats, formjacking doesn’t require the installation of malware on users’ devices. Instead, it targets the website directly, making it challenging to detect.
This technique threatens any organization engaged in online payment transactions, jeopardizing consumers by exposing them to risks such as credit card fraud, identity theft, and various fraudulent activities. Moreover, it has the potential to harm a company’s reputation significantly.
Risks Associated
According to the reports by Feroot, there were 1.5 million formjacking attacks in the first quarter of 2019, averaging over 500,000 attacks per month.
Formjacking poses risks as it involves the unauthorized and surreptitious collection of sensitive information users enter on websites. Here are the key privacy risks associated with formjacking:
Financial Risk:
One of the primary risks of formjacking is financial loss. Attackers target sensitive information, such as credit card details, during online transactions. Stolen financial data can lead to unauthorized transactions, draining bank accounts, or making fraudulent purchases.
Identity Theft:
Formjacking exposes individuals to the risk of identity theft. Cybercriminals can use the stolen information, including names, addresses, and credit card details, to impersonate victims and engage in various forms of identity fraud.
Unauthorized Transactions:
With access to credit card details obtained through formjacking, attackers can initiate unauthorized transactions. Victims may only become aware of these transactions when they check their bank statements, leading to disputes and potential challenges in recovering funds.
Compromised Personal Information:
Beyond financial data, formjacking can also compromise other personal information entered into online forms, such as social security numbers, phone numbers, and addresses. Cybercriminals exploit this information for various malicious activities, including targeted phishing attacks.
Unauthorized Data Collection:
Formjacking involves injecting malicious code into websites to capture user-entered data during transactions, particularly in online forms. This unauthorized collection includes sensitive information such as credit card details, names, addresses, and other personally identifiable information (PII).
How to Prevent Formjacking
Keep Software Updated:
Ensure that your operating system, browsers, and security software are updated. Regularly updating these components helps patch vulnerabilities that attackers could exploit.
Use Verified Websites:
Stick to reputable and well-known websites, especially when making online transactions. Verify the website’s legitimacy by checking for secure connections (https://) and looking for trust indicators.
Browser Security Settings:
Adjust your browser’s security settings to enhance protection. Activate features like pop-up blockers and configure security settings to detect and prevent malicious activities.
Install Antivirus Software:
Install antivirus and anti-malware software on your device. These tools can help detect and remove malicious code or scripts, including those associated with formjacking attacks.
Note: Consider using the qikfox browser, the first browser with a built-in antivirus that instantly blocks malicious code or scripts. The qikfox antivirus offers three categories of functions: full scan, smart scan, and scan downloads, providing extra advantages compared to others by detecting, eliminating, removing, or deleting harmful cyber attacks.
Virtual Private Network (VPN):
Use a VPN to encrypt your internet connection and mask your IP address. This adds an extra layer of security when transmitting sensitive information online, making it more difficult for attackers to intercept data.
Be Careful with Personal Information:
Be cautious about the information you provide online, especially on forms. Only provide the necessary information, and avoid saving sensitive details on websites unless required.
Use a Secure Browser:
Use a secure browser, like the qikfox web browser, that prioritizes user safety, security, and privacy.
qikfox browser has a safe browsing and safe search feature that shows only safe and verified search results with the help of “verify this site” feature, preventing the users from accessing any unsafe website that may engage in formjacking.
Moreover, qikfox’s inbuilt antivirus system protects the users from cyberthreats like viruses and malware. qikfox browser integrates an advanced inbuilt antivirus system featuring Full Scan, Smart Scan, and Scan Downloads options. Full Scan thoroughly examines all volumes for threats, while Smart Scan targets newly modified or opened files. Scan Downloads quickly checks designated folders for downloaded or active files. This robust antivirus ensures rapid threat detection and protection for web users.
FAQs:
