In late June in Bulgaria, a security breach against the National Revenue Agency (NRA) was found, and tax information of millions of adult taxpayers was leaked. Bulgarian Finance Minister Vladislav Goranov said he had confirmed that hackers had intruded into the NRA network from outside, but did not specifically explain what the leaked information was.
Local media outlets in Bulgaria reported that they received emails containing leaked information from self-proclaimed hackers who allegedly breached data. The e-mail included the tax filing service and NRA internal information. In addition, the information stolen by a self-proclaimed hacker was about 11GB, and I still wrote an email with more than 10GB of data.
According to officials, the e-mail used for the intrusion came from within Russia. Accordingly, the hacker who sent the e-mail broke into the 110 database that stored confidential information, including secrets from the IRS. It is said that a country with a population of 7 million had access to corporate tax information of 5 million citizens and foreign workers and stole some of them.
Information that may have been leaked to the local media goes back to 2007 information, such as social security numbers, income, and medical information. However, Minister Goranov said the leaked information did not affect Bulgaria’s domestic finances or finances.
