  • During the development of our DataShadow product, our security researchers discovered a sensitive open database accessible to anyone with a browser and internet connection.
  • We made efforts to identify the owner of this database, and came to the conclusion that it was owned by Amber Commercial (Amber U.P.V.C. Fabrications Limited).
  • We made increasingly escalating attempts to contact those responsible for securing the database in order that they could close the data leak following Amber Commercials own publicly listed policies. 
  • We also contacted Amber Commercial through their preferred mechanism for reporting privacy issues as stated in their privacy policy on their website:
    • “If you suspect any misuse or loss or unauthorised access to your Data, please let us know immediately by contacting us via this e-mail address: [email protected]
  • The company was unresponsive and those we communicated with closed the database after disclosure but then refused to interact with us. 

Due to the sensitive nature of the data, which we judged to be of high risk to the rights and freedoms of individuals involved, our number one priority was to close this security hole.

Since this data has probably been publicly accessible for a long time, our intention is to ensure the affected individuals are informed of the breach so they can act appropriately to protect themselves.

Disclosure Process

TurgenSec worked in line with its Responsible Disclosure Policy at all times, triaging the database the minimum amount to ascertain whether or not it should be in public domain, and when it was clear it should not be, who its owner was.
