![]() To access the same content via the CloudFlare gateway, the URL would become: Screen capture from the public gateway checkerĪn example of a complete path to access an IPFS content via the ipfs.io gateway looks like this: To summarize, a gateway is an IPFS peer that accepts HTTP requests for IPFS CIDs, allowing users to use their default browsers to access the IPFS content.Ī list of current gateways and their status can be found online at: įigure 4. The second way consists of accessing content via so-called “IPFS gateways.” These gateways are used to provide workarounds for applications that don’t natively support IPFS. The computer runs an IPFS daemon in the background, which the browser uses to natively access the IPFS content. Currently, only Brave browser supports IPFS. The first way consists of using a browser that handles the IPFS protocol natively. Converting CID v0 to CID v1 IPFS data browsingĬIDs and their corresponding files can be accessed via two ways. It is possible to convert CID v0 to the CID v1 format:įigure 3. The CID v0 format is made of 46 characters and always start with the characters “Qm”, while the CID v1 format uses base32. It should also be noted that a file will have a different CID if it is modified in any way. ![]() This is why IPFS is said to be content-addressed. ![]() A file will always have the same CID, no matter where it is stored. The CID is a string of letters and numbers unique to files. The storage of those files is addressed by a cryptographic hash of its content, known as the content identifier (also called CID). In the P2P model adopted by IPFS, a given file might be located on a number of different IPFS peers. Therefore, the client-server model of the web is said to be location-addressed. The users’ computer requests the DNS system to know where the data is located and fetches it from that location. When browsing the internet, users generally access URLs, such as, for example. This method makes it possible for any user, including cybercriminals, to create a free account on an online service and start hosting content on the IPFS network, without necessarily running a node on their own infrastructure. This way, more nodes can provide the file. Once a file is requested by a node that does not have it, the file is copied so it can be shared for others later. To start sharing files on IPFS, users can download and use an IPFS Desktop client, API or use online services. IPFS is a bit different, in the way that there is no central web server providing the data: it can be provided by any of the peers (also called nodes) hosting the data. Most of the time, that content is hosted on a single web server, which serves its content to every computer requesting it. ![]() This data can be web pages, files, or just any content that is accessible via an internet browser. In a very simplified view, the way it works on the internet is that different computers request data from different web servers. Most of the actual content hosted on the web is served via web servers. Let’s try comparing it to the way the usual web works. It is a decentralized storage and delivery network, which is built on the principles of P2P networking and content-based addressing. IPFS stands for Interplanetary File System. We will also discuss emerging new cybercrime activities abusing the IPFS protocol and detail how cybercriminals already consider IPFS for their deeds. In this article, we briefly detail what IPFS is and how it works at the user level, before providing up to date statistics about the current usage of IPFS by cybercriminals, especially for hosting phishing content. Unfortunately, it also provides opportunities for another part of the population: cybercriminals. IPFS allows users to host or share content on the internet at a more affordable price, with availability and resiliency capabilities. A notable system that has emerged in recent years is IPFS system, a decentralized storage and delivery network based on peer-to-peer (P2P) networking and belonging to the emerging “ Web3 technologies.” With the rise of new technologies, innovations keep appearing that help us with our various activities.
