Top 4 FTP Exploits Used Hackers and the Solutions
Enterprises rely on safe and reliable information access methods to meet today's rapidly developing market demand. Accordingly, sharing data internally and externally is essential for any organization.
File Transfer Protocol FTP is one of the earliest and still used data sharing methods. Although IT teams and business users are familiar with this, FTP lacks much vital security, compliance, and workflow requirements in modern organizations, especially in data security.
The following are four different FTP vulnerabilities attacked by hackers:
1. Anonymous authentication
Anonymous authentication is an FTP vulnerability, which allows users to use FTP username or log in anonymously. In many cases, users will provide their email address as a password. However, the user's login credentials (username and password) and the commands used are unencrypted, visible, and easy to access. At the same time, any data sent via FTP or hosted on an anonymous FTP server will not be protected. Once, the FBI found that hackers actively used FTP to target medical and dental industries and access protected health information.
2. Directory traversal attack
Directory traversal attack is another FTP vulnerability, and its successful attack will overwrite or create unauthorized files, which are stored outside the Webroot folder. In turn, the original FTP owner is subject to the permission of files or directories and the control of hackers.
3. Cross-site scripting
When attackers use Web applications to send malicious code, XSS attacks are usually sent to end-users in the form of browser-side scripts. Defects that allow attacks to succeed are very common and may occur anywhere where user input is used without verification or coding in the output generated by Web applications.
Attackers can use XXS to send malicious scripts to unsuspecting users. The end user's browser cannot know that the script is not trusted and execute the script. Because the malicious script thinks that the script comes from a trusted source, it can access any data, session token, or other sensitive information stored on the user's local terminal that is reserved by the browser and used with the site.
4. Malware attack based on Dridex
It was discovered for the first time in 2014 that Dridex malware has been re-invented and introduced in unexpected ways after the UK became the target of bank attacks. Internet users targeted by Dridex malware will open Word or Excel email attachments, which will cause macros to download the malware and infect computers, thus exposing users to bank theft. In the latest version of Dridex malware, hackers use FTP sites and credentials to avoid being detected by e-mail gateway and network policy of trusted FTP. Updating FTP credentials regularly can help prevent Dridex-based attacks.
As far as the FTP server itself is concerned, it can no longer meet the system functions required by the big data business in the information age. From the point of view of security, transfer efficiency, and compliance, the FTP server itself cannot be expanded and it is very likely to bring high-cost loss. In the big data market, big file transfer (MFT) software came into being and was promised to meet the above business requirements.
Large file transfer technology provides higher control and security than FTP, which usually has the following features:
In-depth report (e.g., notification of completion of file transfer)
The global visibility of all data transfer activities
End-to-end security, encrypting data in transit and at rest
Performance indicators, monitoring, and support for compliance requirements
