MMO game Street Mobster leaking data of 1.9 million users due to critical vulnerability

Reading Time: 3 minutes
Attackers could exploit the SQL Injection flaw to compromise the game’s database and steal user data.
The CyberNews.com Investigation team discovered a critical vulnerability in Street Mobster, a browser-based massively multiplayer online game created by Bulgarian development company BigMage Studios.
Street Mobster is a free to play, browser-based online game in the mafia empire genre where players manage a fictional criminal enterprise. The game boasts a 1.9+ million player base and stores a user record database that can be accessed by threat actors by committing an SQL Injection (SQLi) attack on the game’s website.
Other games created by BigMage Studios are also potentially vulnerable to the same type of attack, which means that there is a possibility that even more users might be at risk.
The records that can be compromised by exploiting the SQLi vulnerability in Street Mobster potentially include the players’ usernames, email addresses, and passwords, as well as other game-related data that is stored on the database.
Fortunately, after we reported the vulnerability to BigMage Studios, CERT Bulgaria, and the Bulgarian data protection authority, the issue has been fixed by the developers and the user database is no longer accessible to potential attackers.
What is SQL Injection?
First found back in 1998, SQLi is deemed by the Open Web Application Security Project (OWASP) as the number one web application security risk.
Even though this vulnerability is relatively easy to fix, researchers found that 8% of websites and web applications are still vulnerable to SQLi attacks in 2020. Which, from a security perspective, is inexcusable. So much so, in fact, that UK internet service provider TalkTalk was hit with a record £400,000 fine over succumbing to a cyberattack that involved SQLi.
The vulnerability works by injecting an unexpected payload (a piece of code) into the input box on the website or in its URL address. Instead of reading the text as part of the URL, the website’s server reads the attacker’s payload as code and then proceeds to execute the attacker’s command or output data that would otherwise be inaccessible to unauthorized parties. Attackers can exploit SQLi even further by uploading pieces of code or even malware to the vulnerable server.
The fact that Street Mobster is susceptible to SQLi attacks clearly shows the disappointing and dangerous neglect of basic security practices on the part of the developers at BigMage Studios.
How we found this vulnerability
Our security team identified an SQL Injection vulnerability on the Street Mobster website and were able to confirm the vulnerability by performing a simple command injection test on the website URL. The CyberNews team did not extract any data from the vulnerable Street Mobster database.
What’s the impact of the vulnerability?
The data in the vulnerable Street Mobster database can be used in a variety of ways against the players whose information was exposed:
By injecting malicious payloads on Street Mobster’s server, attackers can potentially gain access to said server, where they can install malware on the game’s website and cause harm to the visitors – from using the players’ devices to mine cryptocurrency to redirecting them to other malicious websites, installing malware, and more.
The 1.9 million user credentials stored on the database can net the attackers user email addresses and passwords, which they can potentially use for credential stuffing attacks to hack the players’ accounts on other gaming platforms like Steam or other online services.
Because Street Mobster is a free-to-play game that incorporates microtransactions, bad actors could also make a lot of money from selling hacked player accounts on gray market websites.
What to do if you’ve been affected?
If you have a Street Mobster account, make sure to change your password immediately and make it as complex as possible. If you’ve been using your Street Mobster password on any other websites or services, change that password as well. This will prevent potential attackers from accessing your accounts on these websites in case they try to reuse your password for credential stuffing attacks.
However, it’s ultimately up to BigMage Studios to completely secure your Street Mobster account against attacks like SQLi.
Disclosure and lack of communication from BigMage Studios
Following our vulnerability disclosure guidelines, we notified the BigMage Studios about the leak on August 31, 2020. However, we received no reply. Our follow-up emails were left unanswered as well.
We then reached out to CERT Bulgaria on September 11 in order to help secure the website. CERT contacted the BigMage Studios and informed the company about the misconfiguration.
Throughout the disclosure process, BigMage Studios stayed radio silent and refused to get in touch with CyberNews.com. Due to this reason, we also notified the Bulgarian data protection agency about the incident on October 9 in the hopes that the agency would be able to pressure the company into fixing the issue.
Eventually, however, BigMage Studios appear to have fixed the SLQi vulnerability on streetmobster.com, without informing either CyberNews.com or CERT Bulgaria about that fact.

GR8 Tech Expands Virtual Sports Portfolio with New Basketball Offering, Deepens Localization Strategy
Reading Time: 2 minutes
GR8 Tech has expanded the virtual sports lineup within its ULTIM8 Sportsbook with a new range of virtual basketball, continuing a year of investment in the category that has already seen the addition of virtual horse racing and virtual cricket roulette—a unique format blending casino mechanics with the sport of cricket.
The expansion builds on GR8 Tech’s established strength in cricket, where the company developed one of the industry’s most comprehensive betting lines. Virtual cricket was designed to fill gaps between real-world tournaments, giving operators a way to maintain player engagement year-round—a model now being applied to basketball for markets where the sport dominates.
This content independence stems directly from GR8 Tech’s in-house trading capabilities.
“One of the things that GR8 Tech stands out for is the quality of the trading and the fact that we perform extremely well in very difficult environments, like Asia,” said Dinos Doxiadis, Head of Sportsbook Business at GR8 Tech. “Even our clients’ players in these challenging markets don’t behave like typical players in ‘easier’ regions such as Latin America, we still manage to achieve some of the highest margins there.”
That trading foundation enables GR8 Tech to build and localize content for specific markets rather than relying solely on third-party providers.
“We already have a very strong sportsbook, and now we’re scaling our processes and output capabilities to take it even further,” Doxiadis explains. “We’re improving the product and creating the conditions to localize very quickly and offer a truly localized experience across the world.”
GR8 Tech is also investing in infrastructure to give operators greater control over how they deploy this content.
“The goal is to put even more power into the hands of our operators so they can tailor the product exactly as they want. As we move forward with new data and content agreements, they’ll gain an even greater ability to adapt the sportsbook to their specific needs—on top of what they can already do today.”
Personalization is central to that roadmap. “We have delivered quite a few recommendation models, and right now we can serve custom content on a user level, and we will continue working in this direction,” said Doxiadis. “We have a very good infrastructure and baseline to invest in.”
