After several days of consideration, the administrators of Versus Market decided to retire.
In a post on May 18, 2022, AlphaBay administrator DeSnake published an announcement on Dread about “security issues on Versus.” DeSnake then worked with the Dread user /u/threesixty to verify the existence of the vulnerability discovered by the hacker.
WilliamGibson, a Versus staffer, announced the market's shutdown on Dread.
DeSnake’s explained the exploit in his Dread post:
“The exploit is extremely simple but compromising. It allows for full access to the underlining file system on the server. This include information within the /etc/ directory as well as wallet directories. It is a full information compromise of the system. Everything to the server’s IP address, to the backup of the database in the admin home folder, to the wallet files themselves. I am able to traverse nearly the entire file system with web server level access. There is no jail, WAF, and minimal care to limit the information disclosure in the event of a web server compromise. I am able to view the history of IP addresses which have previously accessed the server.”
Paris, the co-administrator of Dread, later verified the exploit’s existence.
The market has been unreachable since DeSnake published the disclosure on Dread, if not earlier (the market’s backend returned a “white screen of death” after some of DeSnake’s testing). On May 22, 2022, Versus Market staff member /u/WilliamGibson announced the market’s permanent retirement. In the announcement, WilliamGibson wrote that Versus Market’s staff spent several days analyzing the severity of the vulnerability.
“After an in-depth assessment, we did identify a vulnerability which allowed read-only access to a 6+ month old copy of the database as well as a potential ip leak of a single server we used for less than 30 days,” WilliamGibson wrote.
The market wanted to contest some of the claims made about the vulnerability. Specifically, WilliamGibson wrote, “there was no server pwn and users/vendors have nothing to worry about as long as standard and basic opsec practices have been utilized (for example, PGP encryption).” Members of the market’s team feel as if a “clear agenda” existed in the way people handled the discovery and disclosure of the vulnerability.
Versus Market was the most popular Western marketplace
Others on Dread have questioned DeSnake’s involvement in the disclosure, pointing out that AlphaBay inevitably benefits from the demise of any competition. One Dread user asked, “all good intentions aside. Isn’t it an advantage to eliminate your competition and gain more users for your own marketplace?”
DeSnake answered the question, stating, “yes it is and we do not hide that. As I explained in several posts some minutes ago the effect of such a vulnerability is much, much bigger to all marketplaces and the scene as a whole and while we do benefit from it, it is a small if not insignificant compared to what could have actually happened.”
Paris provided a similar answer and suggested that law enforcement had already compromised the server unless they were “sitting on their hands.”
The sentiment of users commenting on posts about the vulnerability appears to be generally balanced. Although many are skeptical of the way the motivations for DeSnake’s disclosure, others thanked the parties involved for “not outright exposing the exploit and/or leaking the database.” (DeSnake claimed that he did “not leak the database or [steal] any coins.” The market recovered from a Bitcoin theft once before when hackers drained Versus’ escrow wallet).
DarkDotFail claims the market had “a troubled history.”
WilliamGibson’s retirement post highlighted the market’s climb to the top.
“We built Versus from scratch and ran for 3 years. We built a community and even became the #1 DNM when we never intended for that to be the goal. At a certain point, there is no further way up to go, only down, and in this business it is best to not make decisions out of pride. While we are not ending on the note that we would have liked, we hope that the truth about the actual scope of the vulnerability, combined with the impact we have had on the community, leaves users remembering Versus fondly for years to come. Versus Market has officially retired and we thank you for your support and being part of something that hopefully defined the future of DNM’s.”
And he closed by thanking the community and telling Versus Market vendors that he will provide a link where they will be able to access their transactions without a locktime.
