Telegram has a security leak: uncovered passwords and documents


The Telegram Passport app does not support cyber attacks


Earlier in the week, Telegram opted for a new Telegram X app to get around censorship and improve security on its platform, one of its strengths against its competitors. However, the application of the Durov brothers also has problems.

The development of Telegram Passport has opened a door to cyber attackers that allows access to passwords and official documents stored on the platform.

The vulnerability lies in the SHA-512 password protection system used by Telegram Passport, which uses an algorithm that is not intended for the storage of this type of keys and is vulnerable, as the cybersecurity company Virgil Security has warned through your web

On July 26, Telegram integrated in its application the new Passport tool, an authentication method for online services to which users can upload their official documents such as passports, driving licenses and bank details, and identify with them.

The developer of Telegram explained when announcing the function that protected the security of files and keys through end-to-end encryption mechanisms, also present in the messages of the app.

Passport uses a password as the only protection mechanism to identify itself in external services. Due to the encryption protocol used, cyber attackers can use high-performance graphics cards such as those used to mine cryptocurrencies to automatically generate combinations of random characters.

By means of this mechanism it is possible to find out any password of eight characters in length in 4.7 days. In this way, a brute-force attack could guess any Telegram Passport password with an electricity cost of between 5 and 135 dollars (from 4.3 to 116 euros, at the change), according to experts in cybersecurity.

                               Year one post roaming What do you need to know in order not to overpay if you travel in Europe? Far is left when one stepped on Paris or Berlin and looked for places to connect to the wifi to share with friends the photos of the trip. It has been a year since the technology frontiers in Europe have fallen and now any citizen can use the mobile networks of any country in the Old Continent - including Iceland, Liechtenstein and Norway - at no extra cost. Goodbye surprises at the time of arrival of the days of rest for an excess in the bill of the mobile. A measure that, with the value of technology today, has been almost as important as the 1992 Maastricht Treaty, which gave the green light to the free movement of people in the Schengen area. Like any rule, it had a small print that it still maintains . On the ...

Keys to the new government tax that big technology does not like

Keys to the new government tax that big technology does not like It is still unknown how much will be collected but the law will be processed "imminently", although some multinationals have already complained Amazon, Facebook, Google or Twitter have in common that their fundamental business is based on the sale of advertising 'online', in the intermediary activities of digital platforms or in the commercialization of data that is generated with information provided with the user. Therefore, these companies -among others- will pay in Spain the new tax on technological platforms promoted by the Montero cabinet. These are the three assumptions that the finance minister detailed as the bases on which the "imminent" rate for digital services would be based. Although he placed special emphasis on his first appearance before the Finance Committee in Congress where this newly created tax "will not affect SMEs or medium-sized companies", the...

"These rules will ensure that flights are safe even when our skies are more and more traveled," said Bulgarian Transport Minister Ivaylo Moskovski, on behalf of the country that represents the Council this semester, after learning of the agreement reached in Luxembourg. It will enter into force this summer once it is published in the Official Journal of the EU. So far, drones under 150 kilos are regulated by national authorities, leaving manufacturers and operators at the expense of different design and safety requirements....
