Imagine: after a busy day in the office, you finally come home to calm down and fall asleep in a comfortable bedroom. Just enjoying a quiet time, a buzz came and you didn't want to move. But in the end, you reluctantly opened your eyes from the warm bed and picked up the noisy work phone-there is urgent work! Urgent files to be transmitted. This situation is not only a terrible nightmare but also a reality for many people. The lack of suitable office tools has greatly affected the productivity and opportunity of enterprises, among which file transfer software is an important office tool, especially in the era of big data. From life information exchange to value mining behind commercial big data, more and more industries and activities need to involve large file transmission. In this paper, we will discuss several key points of solving the problem of file transmission by combining Raysync with UDP, so that we can better understand modern file transmission products. Based on the transmission performance of UDP, Raysync breaks through the defects of traditional FTP and HTTP transmission, the transmission rate is increased by 100X, and the bandwidth utilization rate is over 96%. Multi-dimensional transmission mode meets the requirements of extremely fast transmission of TB-level large files and massive small files. Intelligently accelerate the transmission in the whole process, avoid packet loss caused by network latency, greatly accelerate the efficiency of file outgoing, effectively compress the length of file outgoing, and provide a perfect data transmission carrier. Long-distance transmission is easy File transfer may not be so urgent, and stable and complete file transfer is the most important thing at the moment. In order to prevent you from worrying about whether your files will arrive safely at overseas partners, it is necessary to find a high-speed, safe, and reliable file transfer software. Yes, there are free UDP file transfer tools, but the GB transfer limit of most tools is very low. If you have any questions about using UDP protocol, Raysync is happy to provide you with the preventive measures we have taken. It is easy to transmit large files in a long-distance and weak network environment. Stable and reliable file transmission Over the years, data attacks such as data leakage and hacker attacks have emerged one after another. It is very common for traditional file transmission methods to lose data packets during transmission, but this situation means that your production, research, business, and other aspects may face corresponding delays, and you may face high compensation in severe cases. The importance of file transfer is often underestimated, so there is usually no proper budget. Don't be afraid, understand that you have many choices, including flexible pricing, which will prevent you from sacrificing data. With the help of our UDP technology, the Raysync will minimize the packet loss rate, make the files stably transmitted, greatly reduce the time cost of enterprises, and effectively guarantee the benefits of enterprises. Multi-task efficient processing Adhering to the free UDP file transmission method may limit the customization options. You are limited to one user profile, and usually only one transmission task can be performed at a time. Therefore, you must prioritize the equally important items for transmission. But most of the time, this sort itself is unreasonable. What we need is software that can respond quickly to support the rapid development of business. Raysync is based on multi-industry service experience, and it is well known that enterprises should know the number of configuration files supported by the software and the number of processing tasks when choosing file transmission software. In multi-task processing, Raysync has a number of multi-user accounts and supports user-defined permissions and transmission settings. Raysync has helped Huawei, OPPO, VIVO, and many other famous enterprises solve the difficulties in large file transfer.

E-mail is still the most popular attack medium. Legitimate e-mails are attacked during transmission and hijacked in complicated ways, while phishing emails try to deceive people with fake addresses, which is a typical phishing attack . How to respond to the chain attach via email? Virus software purchases an email account through the email response chain. Attackers use phishing, violence or social engineering to access one or more email accounts, and then start to observe the conversation, and seek opportunities to send malicious software or malicious links to one or more participants in the ongoing communication chain. What types of malware use response chains as attack vectors? In 2017, the attack on the email response chain was first discovered. In 2018, Gozi ISFB/Ursnif Banking Trojan horse activities also began to use this technology; In other cases, attackers break legal accounts and use them to take over existing threads and spam attacks on other recipients. Malicious attachments can use VBScript and PowerShell to transfer workloads, such as emote, Ursnif, and other loaders or bank trojan malware. Ordinary fraudulent emails are usually sent in the form of topics or short messages, which are easy to identify and have less chance of being deceived. However, attacks through e-mail response chains are often carefully considered, without grammatical errors and with clear semantics. This means that even the most cautious and well-trained employees may become victims. Four methods to prevent email response chain attack Since the response chain attack is based on account compromise, it should be ensured that all employees of the company follow the verified security procedures. These include two-factor or multi-factor authentication, with a password set for each account. Secondly, the use of Office macros should be restricted or completely prohibited as much as possible. Although these are not the only means by which malicious attachments may endanger devices, macros are still common attack vectors. Introducing safety awareness training is of great help to train employees to understand the dangers of phishing. E-mail users need to raise people's awareness of phishing attacks and how attackers develop their technologies. Information assets are very valuable for enterprises, so it is better to deploy a data transfer solution as soon as possible instead of preventing this and that. Raysync adopts self-developed transfer protocol, which can help enterprises to quickly distribute large files or massive small files, and can provide the highest transfer speed with minimum system overhead regardless of the distance of transfer or the strength of network conditions; Security is also the focus of Raysync. The whole process of file transfer adopts financial AES-256 encryption transfer to ensure data security. The mechanism of breakpoint continuous transfer and error automatic retransfer ensures that the transfer can continue from the breakpoint after unexpected interruption of transfer, ensuring the integrity and reliability of file transfer, and monitoring the whole process log to ensure considerable, searchable and traceable data.
