Hacker reportedly changed website location of the QR-codes on historical buildings of Russian city Astrakhan and replaced them with adult website link. There was no technical detail provided how hacker was able to change the location of QR code.
When residents and guests of the city scanned QR-codes, their phones opened resources for adults, instead of sites with historical references.
Galina Goteeva, the Minister of Culture and Tourism of the region, said on March 15 that the signs with QR codes on the historical buildings of Astrakhan were changed.
QR-codes on historically significant buildings of Astrakhan were placed a few years ago. It was assumed that people can get a historical reference about the building after scanning the code with a mobile phone. Already in November last year, the Media reported about QR codes leading to porn sites and dating sites for quick sex.
In fact, the Regional Ministry of Culture for a long time struggled with the elimination of porn content, the signs were removed with great difficulty. And only at the end of the year sex traffic was stopped completely.
However, it is still a mystery why the signs with QR-codes hung for so long and why they were not promptly replaced. In total, there are at least 15 signs. QR-codes stopped working more than a year ago, but officials did not pay any attention to it: first, the pages gave an error, and later they began to lead to porn sites.
