Cloak : A Censorship Circumvention Tool To Evade Detection By Authoritarian State Adversaries

Cloak is a pluggable transport that enhances traditional proxy tools like OpenVPN to evade sophisticated censorship and data discrimination.

Cloak is not a standalone proxy program. Rather, it works by masquerading proxied traffic as normal web browsing activities. In contrast to traditional tools which have very prominent traffic fingerprints and can be blocked by simple filtering rules, it’s very difficult to precisely target Cloak with little false positives. This increases the collateral damage to censorship actions as attempts to block Cloak could also damage services the censor state relies on.

To any third party observer, a host running Cloak server is indistinguishable from an innocent web server. Both while passively observing traffic flow to and from the server, as well as while actively probing the behaviours of a Cloak server. This is achieved through the use a series of cryptographic steganography techniques.

Cloak can be used in conjunction with any proxy program that tunnels traffic through TCP or UDP, such as Shadowsocks, OpenVPN and Tor. Multiple proxy servers can be running on the same server host and Cloak server will act as a reverse proxy, bridging clients with their desired proxy end.

Cloak multiplexes traffic through multiple underlying TCP connections which reduces head-of-line blocking and eliminates TCP handshake overhead. This also makes the traffic pattern more similar to real websites.

Cloak provides multi-user support, allowing multiple clients to connect to the proxy server on the same port (443 by default). It also provides traffic management features such as usage credit and bandwidth control. This allows a proxy server to serve multiple users even if the underlying proxy software wasn’t designed for multiple users

Cloak also supports tunneling through an intermediary CDN server such as Amazon Cloudfront. Such services are so widely used, attempts to disrupt traffic to them can lead to very high collateral damage for the censor. Buildgit clone https://github.com/cbeuw/Cloak

make ConfigurationExamples of configuration files can be found under example_configfolder. ServerRedirAddris the redirection address when the incoming traffic is not from a Cloak client. Ideally it should be set to a major website allowed by the censor (e.g. www.bing.com) BindAddris a list of addresses Cloak will bind and listen to (e.g. [":443",":80"]to listen to port 443 and 80 on all interfaces) ProxyBookis an object whose key is the name of the ProxyMethod used on the client-side (case-sensitive). Its value is an array whose first element is the protocol, and the second element is an IP:PORTstring of the upstream proxy server that Cloak will forward the traffic to.

Example:

{
“ProxyBook”: {
“shadowsocks”: [
“tcp”,
“localhost:51443”
],
“openvpn”: [
“tcp”,
“localhost:12345”
]
}
} PrivateKeyis the static curve25519 Diffie-Hellman private key encoded in base64. BypassUIDis a list of UIDs that are authorised without any bandwidth or credit limit restrictions AdminUIDis the UID of the admin user in base64. You can leave this empty if you only ever add users to BypassUID. DatabasePathis the path to userinfo.db, which is used to store user usage information and restrictions. Cloak will create the file automatically if it doesn’t exist. You can leave this empty if you only ever add users to BypassUID. This field also has no effect if AdminUIDisn’t a valid UID or is empty. KeepAliveis the number of seconds to tell the OS to wait after no activity before sending TCP KeepAlive probes to the upstream proxy server. Zero or nega[...]
