OnionScan: Check to ensure your dark web site is truly anonymous

OnionScan is a free and open source tool for investigating the Dark Web.

Websites on the so-called dark web are created to protect the anonymity of both their owners and visitors. Plenty of administrators make mistakes in setting them up, often leading to the server’s genuine IP address being leaked, or they might leave identifying metadata in files uploaded to the site.

Now, a scientist has established a custom-made tool for immediately scanning Tor hidden services for a variety of problems and vulnerabilities, meaning any individual, from dark web drug lords to people hosting whistle-blowing platforms, can make sure that their site really is safeguarded.

“I want anonymity tools to be the very best; there are people whose lives depend upon them,” Sarah Jamie Lewis, the independent security scientist who came up with the tool, told Motherboard in an encrypted chat.

“However, what I also found was many, many sites failing basic security practices like the above. So many that I started to write a tool to help me catalog them — and this is where the tool came from,” Lewis said. “If so many of those sites are failing themselves and their users, i am willing to bet so are anonymous political blogs and other users who desperately need the anonymity.”

“OnionScan,” as the program is called, checks sites for issues that may unmask servers or determine their owners. That may be an open server status page, which enables any individual to see what other sites are being hosted by the exact same individual. Or there might be metadata in images on the site, revealing GPS collaborates of where they were taken.

“While doing some research study earlier this year I kept coming across the very same issues in concealed services– exposed Apache status pages, images not removed of exif information, pages exposing details about the tools utilized to develop it with, etc.

It works “quite much the like any web security scanner, just tailored for deanonymization vectors,” she continued.

OnionScan is not subtle. “It deserves keeping in mind that the software is noisy; it requires to make a number of demands to download images and files,” Lewis said. “It stands out like a sore thumb in logs.”.

Lewis started her research study with dark web markets, assuming that they would have developed some cool security functions. The marketplace AlphaBay has actually made it necessary for suppliers to use two-factor authentication.

Other scientists have formerly reported quite major issues with how concealed services have actually been configured. UK-based Thomas White discovered the IP address of the now-defunct Kiss Market, in addition to that of a dark web scams market. In June of last year, White asserted to have actually collected details on more than 500 sites, and the IP addresses of eight.

In future updates, Lewis’ tool will also pull other potentially recognizing data, such as PGP keys and comparing the different software used to generate them.
