In the daily surfing life on the Internet, people often overlook a problem. When we use peer-to-peer software to access multiple media files, such as books, music, movies, or games, the danger is also closely followed. Peer-to-peer file sharing is the use of peer-to-peer network technology to distribute and share digital media. Take BitTorrent, a popular file-sharing protocol, as an example. It was created by Bram Cohen for P2P file sharing and is a P2P file transfer protocol based on TCP/IP protocol. P2P file-sharing has many uses, especially among enterprises. But the reality is that the file-sharing protocol BitTorrent is a controversial subject in the security world. Especially, BitTorrent enjoys a "high reputation" in piracy when copyright protection and illegal content are shared equally. It is estimated that nearly one quarter of Internet traffic infringes copyright. In 2017, the most popular BitTorrent index on almost all the top 50 most popular search phrases is the name of copyright movie or TV program. If users want to use VPN to access P2P file sharing sites, they may want to access illegal content anonymously. If they download illegal content, they are not only responsible for copyright issues, but they can easily download dangerous malicious software without realizing it at all. Although the danger may not be as common as other areas on the Internet, malicious software can still be inadvertently obtained through P2P file sharing. Remember this unfortunate user who stole more than four bitcoins from his computer after downloading pirated video games infected with malicious software? This risk is still very real. According to ZDNet, P2P file sharing websites infect millions of users every month. Raysync is dedicated to ensuring the fast file transfer, while protecting the data security. Raysync provides multiple modes of transfer according to different transfer initiators. It supports the peer-to-peer, multi-point mutual transfer, one-to-many data distribution, and other modes.

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.

For decades, there has been no good solution for enterprises to balance security and productivity in file sharing. Especially in this fast-paced era, people are not satisfied with traditional disk movement, FTP, and email to complete file sharing. People want to work collaboratively anytime and anywhere, so more and more people are turning to file sharing solutions. However, it is worrying that according to the research report, 50% of enterprises have no policy on file-sharing tools. Even if there is a policy, 48% said they would not implement it. More importantly, 69% of small and medium-sized enterprises don't even know whether their employees are using unapproved file-sharing tools or dangerous file-sharing tools. How to strike a balance between employee productivity and protecting critical data? Many employees of enterprises are already using file-sharing software. As mentioned above, this may expose the data of enterprises to the risk of data leakage because of IT compliance. Perhaps it is not intentional for people to leave the company with sensitive documents when they move , but the risks always exist. Instead of letting employees look for various file-sharing tools spontaneously, it is better to integrate a compliant and controllable file sharing tool into the existing office software of enterprises to create a safe and comfortable office environment.

In the era of big data, the amount of data is exploding. Massive small data has become a very typical data application, such as some picture websites, which may need to process hundreds of millions of picture materials every day. Traditional file systems are difficult to deal with the application scenarios of massive small files efficiently, and there are many problems in the operations of reading, storing and transmitting files. Challenge 1: Low file reading performance and difficulty in file retrieval A large number of concurrent random disk accesses greatly reduce the efficiency of disk operation and delay data access. It is much more difficult to retrieve the corresponding files in the voluminous document database, and the time-consuming of business operation is high, even the files can not be opened. Challenge 2: The amount of data is too large and the storage cost is high The data generated in the production process of an enterprise has a very important business value. When we gather a large number of scattered small files together, we will form a complete asset view and business view. However, due to the immature storage technology and high storage cost, a large amount of data has been discarded before it can bring its value into play. Challenge 3: Massive small files are transferred slowly and the transfer performance is poor Traditional transfer tools can't stand the accumulated data. In addition, due to the influence of transfer distance, network environment, and the size of transfer files, packet loss and delay often occurs, which slows down the business process. Challenge 4: Massive data management is difficult Enterprises continuously generate data increment every day, which makes it difficult to manage massive files. Backing up data, deleting files and sorting data will consume a lot of system resources every day. Raysync solves the data transfer problem of enterprises with its excellent transfer performance.
