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 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 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 - 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 - Workflow automation Raysync- large file transfer software High performance Raysync high-speed transfer protocol, the bandwidth utilization rate is over 96%, the transfer rate is increased by 100X, and TB-level large files and massive small files are easily transmitted.

Introducing Several Popular File Transfer Protocols
Before you choose a secure file transfer solution, it is best to have a basic understanding of the protocols involved, which make file transfers safe and reliable. 1.FTP The FTP file transfer protocol has existed for decades and has been widely used in the past. TCP provides reliable data transfer through message sequence confirmation and message retransfer mechanisms; at the same time, various widely used operating systems have built-in TCP protocol stacks, and POSIX standards define the TCP Socket standard API interface, these factors have contributed to TCP's widespread success on a global scale. However, this transfer protocol, which was designed more than 20 years ago, has become increasingly unsuitable for the rapidly developing network environment and the requirements of new applications, especially when there are a certain packet loss and delay on the network transfer path. Transfer throughput declines sharply, and path bandwidth is often not used effectively, resulting in slow transfer speed, long transfer time, and poor transfer experience. 2.FTPS FTPS is an extension protocol that adds Transport Layer Security and Secure Socket Layer encryption protocol support to the commonly used file transfer protocol . FTPS is a secure file transfer protocol that allows you to communicate with trading partners, Clients and users transfer files securely. These transfers can be authenticated through methods supported by FTPS . 3.SFTP In the computer field, it is designed by the Internet Engineering Task Force to provide secure file transfer capabilities through the expansion of SSH-2, but it can also be used by other protocols. Even though the IETF is in the network draft data stage, this protocol is described in the SSH-2 document, it can be used in many different applications, such as secure file transfer in Transport Layer Security and transfer information management in virtual private network applications Program. This agreement is assumed to be executed in a secure channel, such as SSH, the server has authenticated the client, and the client user can use the agreement. Compared with the earlier SCP protocol that only allows file transfer, SFTP allows a wider range of operations on remote files ─ which is more like a remote file system protocol. A comparison of the capabilities of an SFTP client and SCP includes additional replies to interrupt transfers, directory listings, and remote file movement. 4.SCP The old protocol, SCP or Secure Copy Protocol, is a network protocol that supports file transfer between hosts on the network. It is similar to FTP, but SCP supports encryption and authentication functions. 5.HTTP & HTTPS As the backbone of the World Wide Web, HTTP is the basis of data communication. It defines the message format of the communication between the web browser and the web server and defines how the web browser should respond to web requests. HTTP uses TCP as the underlying transfer and is a stateless protocol. This means that each command is executed independently, and the receiver does not retain session information. Https is a secure version of HTTP in which communications are encrypted by TLS or SSL. 6.AS2, AS3, and AS4 AS2, AS3, and AS4 are popular protocols used to send and protect critical file transfers. AS2 is used to transmit sensitive data safely and reliably on the Internet. AS2 uses digital certificates and encryption standards to protect critical information transmitted between systems, networks, and locations. AS 2 messages can be compressed, signed, encrypted, and sent through a secure SSL tunnel. AS3 is a standard and can be used to transfer almost any file type. It provides a layer of security for data transfer through digital signature and data encryption. It was originally created to transfer data files, such as XML and EDI business-to-business data files. Unlike AS2, AS2 is a defined transfer protocol, and AS3 is a message standard that focuses on how to format a message when it is sent from the server to the server. Once the AS3 message is synthesized, it can be transmitted via any other protocol . As long as both parties can access the location where the message has been placed. AS4 is an agreement that allows companies to exchange data securely with their partners. It is based on what was originally set up by AS2, but works with web services and provides improved delivery notifications. As a business-to-business standard, AS4 helps make file exchange on the Internet safe and simple. 7.PeSIT PeSIT protocol is an end-to-end file transfer protocol developed by the French Interbank Telecommunications System Economic Interest Group . It is rarely used in North America and is mainly used to meet European banking standards and to transfer communications to and from European banks. Knowing these 7 file transfer protocols, you probably know how to choose a protocol to ensure the secure transfer of your files.

Isn't It Time You Replaced Your FTP Server?
FTP is designed as a simple mechanism, which can exchange files between computers when the new network and information security are not yet mature. In the 1970s, if you wanted to protect your server from unnecessary access, you just had to lock the computer room door. User access to data is controlled by the basic user ID and password scheme. At this time, the Internet does not exist yet, and the PC revolution will take ten years. Nowadays, the security of business file transfer has become the focus of enterprise protection, especially in computing systems, and file transfer between enterprises and even in cross-border transfer has become crucial for the development of global economy. However, the original native FTP function of TCP/IP is not designed for the file transfer requirements of modern enterprises connecting the whole world. At the same time, due to the progress of network detection technology, the proliferation of hackers, malicious software, and millions of network users, the basic security mechanism of FTP has long been unable to prevent. Risks associated with file transfer using FTP: 1. The native FTP does not encrypt data; 2. When logging in, the user name and password are transmitted in clear text and are easy to identify; 3. FTP scripts and batch files save user ID and password publicly, which is vulnerable to hacker attacks; 4.FTP is used alone, it does not meet the compliance requirements; 5. When using FTP connection, the transmitted data may be "copied" to the remote computer, and may not even reach the intended destination. This possibility will expose your data to third parties and hackers; 6. Regular FTP itself does not maintain file transfer records. Isn't it time you replaced your FTP server? It's time to make a change. First, check how FTP is applied in the enterprise. Secondly, determine how your enterprise manages and protects everyone's file transfer. Finally, determine whether your enterprise can use a secure file transfer solution software Raysync can provide you with a reference for purchase), and then evaluate the software to see how it meets your business needs.

This Powerful Data Transfer Solution Is Used by 99% of Companies
FTP protocol originated from the early days of network computing. A few government and university researchers explored the value of connecting computers together, so they created FTP protocol to promote the movement of files in the network. Why do so many people still use FTP now? Because it is perfect and embedded in most operating systems today. Although FTP is provided free of charge, it does not mean that it has no cost. IT teams spend too much time managing and maintaining FTP servers and their users, which could have been devoted to more important IT projects and plans. Security Many changes have taken place in FTP since it was invented, especially the security and confidentiality. FTP predates the Internet as we know it today, but it is not designed to transfer files safely. When companies use it to send files containing personally identifiable information or patient data, compliance does not exist. FTP has no resistance to many types of attacks, and the user name and password credentials are sent in clear text. It is not difficult for hackers to extract information and access the entire server containing company data. Ease-of-use FTP is mainly an IT tool. Many IT professionals still like to run FTP in command line mode, and take pride in managing servers through text commands, but for ordinary knowledge workers, FTP operation is too technical. FTP client software can help, but it is only an overlay, which will not increase security or reduce manual management of FTP server. The complaints that FTP administrators often hear are managing users and their credentials, and knowing which files should be saved on the server and which files can be deleted. This causes the FTP server to become very bloated. As time goes by, the files on the FTP server continue to accumulate, and the situation will get worse and worse. What transfer tools do we use now? Today's file transfer function has surpassed FTP many times, providing encrypted communication, reporting and tracking functions, integrating with enterprise applications, and being more intuitive. Today's file transfer solutions can meet today's growing demand for secure file transfer. It's time to adopt a more modern and powerful data transfer solution. As time goes by, your company will benefit from this, operate within the scope of compliance standards, and become more efficient after the final rest of FTP.

About the File Transfer Protocol, How Much Do You Know?
Before choosing a secure file transfer solution for an enterprise, it is best to have a basic understanding of the transfer protocols involved: 1.FTP FTP is a very primitive file transfer protocol, which has been popular for decades. FTP uses two separate channels to exchange data, "command channel" to verify user identity and "data channel" to transmit files, but both channels are unencrypted, and any data sent on the channels can be easily utilized. 2. FTPS FTPS is a secure file transfer protocol, which allows you to securely transfer files with your trading partners and customers. File transfer can be authenticated by methods supported by FTPS, such as client certificate, server certificate, and password. 3. SFTP SFTP stands for FTP over SSH . It is a secure FTP protocol and a good alternative to insecure FTP tools. SFTP exchanges data through SSH connection, and provides organizations with high protection for file transfer shared among their systems, trading partners, employees, and the cloud. 4. http&HTTPS Http is the basis of data communication. It defines the message format of communication between the Web browser and Web server and defines how Web browser should respond to Web requests. HTTP uses TCP transfer control protocol as the underlying transmission, which is a stateless protocol, which means that each command is executed independently, and the receiver does not keep the session information. Https is a secure version of HTTP, in which communication is encrypted by TLS or SSL. 5. AS2, AS3, and AS4 AS2, AS3, and AS4 are popular protocols used to send and protect key file transfers. AS2 is used to transmit sensitive data safely and reliably on the network. AS2 uses digital certificates and encryption standards to protect key information transmitted between systems, networks, and locations. AS2 messages can be compressed, signed, encrypted, and sent through a secure SSL tunnel. AS3 is a standard that can be used to transfer almost any file type. It provides security protection for data transmission through digital signature and data encryption. Originally, AS3 was created for transmitting data files, such as XML and EDI business-to-enterprise data files. Unlike AS2, AS2 is a defined transport protocol, and AS3 is a message standard, which focuses on how to format messages when sending from server to server. Once the AS3 message is synthesized, it can be transmitted through any other protocol . AS4 is a protocol that allows enterprises to exchange data securely with their partners. Its predecessor was AS2, but it improved delivery notice based on AS2. As a business-to-business standard, AS4 makes it safe and simple to exchange files online. 6. MFT Managed File Transfer Protocol MFT integrates the advantages of these protocols to help users solve various file transfer problems and improve enterprise efficiency. Raysync is dedicated to meeting the data transfer needs of internal or external partners of enterprises, providing efficient and controllable accelerated transfer of large files, ultra-long-distance, transnational network data transfer, safe outgoing of file assets, file management and organization authority management, supporting local deployment and cloud services, and providing enterprises with safe, stable, efficient and convenient technical support and services for large file interaction.

Best Secure File Transfer Methods in 2020
This is a new decade, and many companies are interacting with customers all over the world. Knowing the options and using secure file transfer methods is essential for any business to stay ahead. Secure File Transfer Method Every file transfer needs to ensure that the transferred data is protected. One way to ensure the protection of customer data is to look for security features that can prevent and avoid man-in-the-middle attacks. This attack is similar to eavesdropping on conversations. During the transmission between the computer and the server or other equipment, your data may be intercepted by the "monitoring" personnel. Secure file transfer methods ensure that eavesdropping and other violations or violations of privacy will not occur. Today, secure file transfer methods are designed to protect your company from data leakage during transfer. From simple online file sharing to the regular transmission of large files and videos, these three secure file transfer methods can help you send business files safely in 2020. 1. SFTP SFTP is a separate protocol from FTP. It uses an SSH key, which is the "S" part of SFTP. What else makes this protocol a secure file transfer method. To transfer SFTP files securely, an SSH key or user ID and password are required to connect to the server. Your FTP and file sharing services should provide information about setting up SSH keys for the account. The SSH protocol includes public keys and private keys, which are used to authenticate servers and users. When using SFTP for file transfer, the connection is always secure. SFTP uses encryption and cryptographic hash functions to ensure that no one can read your data during file transfer. If you are looking for a reliable way to upload and transfer large files, a hosted FTP service that supports direct SFTP connections is perfect for your business. One of the advantages of choosing SFTP as your secure file transfer method is that it is firewall-friendly. SFTP also uses a single port to connect to the server. Once the connection is authenticated, a single open port can transfer files faster between the client and the server. 2. Use FTPS to Improve the Security of the File Transfer Protocol FTPS is an extension of FTP. It uses TLS or SSL encryption to achieve the security that is not available with standard file transfer protocols . This additional layer provides a secure connection between the client and the server. The FTPS protocol requires the following to connect and allow file transfer: User Identity; Password; Certificate . FTPS does use multiple port numbers to connect and complete file transfers. The first port is used for authentication and commands. After verifying and establishing a connection with the server, each file transfer request opens another port. Someone might argue that opening multiple ports may cause security problems. This secure file transfer method is good at server-to-server file transfer. When you need to access an FTP server from a personal device, FTPS is the ideal choice. Software developers who use the .NET framework often use FTPS as their secure file transfer method. When using FTPS, you may find that there is less support for it and more configuration is required. However, the use of FTP's TLS and SSL encryption protocols makes it the preferred file transfer method for many companies. 3. Encrypted Website Connection HTTPS is the Hypertext Transfer Protocol "secure". When you visit the site, we are talking about the content before www. HTTPS means encrypted website connection and HTTP connection. The HTTPS protocol is a way for web browsers to communicate with websites. Cannot monitor or tamper with HTTPS. There is no man-in-the-middle attack. HTTPS checks website security certificates and ensures that you are talking to a real website . Today, most commercial websites use HTTPS by default. However, it is best to check the Hypertext Transfer Protocol when visiting a new website, or whether you receive a warning or pop-up window to confirm that you want to visit that particular website. Look for HTTPS at the beginning of the URL, or look for the lock symbol before the website name in the address bar. If you are using the web interface to access files, it is important to know the type of connection you have. For example, if you want to enter information to place an order online, or request customer information in a form on your website. HTTPS works in conjunction with SSL . Browsing privacy using HTTPS only allows other people to see connections to secure sites. They cannot see the specific page you visited or any other browsing information. Tips for global secure file transfer are used for various data and file transfer protocols. No matter which secures the file transfer method you choose, some other things can reduce security risks and improve workflow. As a secure file transfer method, HTTPS is best used for banking, sending payments, and transferring private or sensitive data from users via website data. Any transmission that requires a password can only be sent using the HTTPS protocol.

Raysync Large File Transfer: How to Choose File Transfer Protocol?
In the process of file transfer, TCP and UDP are transport layer protocols, and their communication mechanisms are different from the application scenarios. The version V5.0.3.8 of Raysync supports the setting of transfer protocol in 4. In order to better answer the question of how users choose file transfer protocol, the following contents make an easy-to-understand short answer to file transfer protocol: - Automatically select UDP/TCP: it will automatically switch to the TCP mode when the transfer latency is less than the value you configured. - Only UDP - Only TCP - Default: The UDP mode will be used in priority, it'll automatically switch to TCP mode when the process of transfer is interrupted. Why are there four transfer protocols? First of all, we should understand the meanings and differences between these transfer protocols: The basic difference between TCP and UDP: TCP refers to the Transmission Control Protocol, and UDP means the User Datagram Protocol. Both of them are the protocol of the transport layer, but they have different mechanisms. - Message mode: TCP designed for the connection-oriented streaming mode, while UDP for connectionless datagram mode. - TCP provides reliable services, and UDP may lose packets. - TCP has the strict requirement of system resources, while UDP not. - TCP transfer efficiency is slow, UDP has good real-time performance, and its work efficiency is higher than TCP. - Each TCP connection can only be point-to-point, while UDP supports one-to-one, one-to-many, many-to-one and many interactive communication. The scenarios of TCP and UDP: In conclusion: TCP is a kind of reliable transfer method but the transfer speed is relatively slow. While UDP is relatively unreliable but has ultra high speed. Therefore, when choosing a specific file transfer protocol, it should be decided according to the requirements of communication data. If the real-time investigation of communication data is far more important than the integrity of communication data, TCP protocol is preferred; On the contrary, UDP protocol is used. The four file transfer protocols supported by Raysync are designed to facilitate users to configure flexibly according to actual transfer requirements. It is not limited to a certain transfer protocol, and is suitable for file transfer requirements of all walks of life. The ultimate purpose of file transfer software provided by Raysync is to help more enterprises realize high-speed data transfer and create value for enterprises.
