Malvertising

Several last weeks the famous Forbes.com portal did not allow readers to get acquainted with the materials if on user side the advertizing disabler is switched on. So, if the reader with AdBlock or uBlock visited Forbes.com, he was asked to move away the disabler. Otherwise to get acquainted with portal content just there was no opportunity. It is difficult to find other opportunity as the same Google does not cache data of a portal correctly.

But a problem not in advertizing and not in disablers. As it appeared after the disabler of advertizing was switched-off by the user, malware under the guise of the normal program was at once offered to it.

The researcher in the field of a computer security from the Netherlands, Guido Vranken [Guido Vranken] found a new method of attack to the traffic ciphered on TLS/SSL. In the theory he allows to retrieve certain information on the data transferred on the HTTPS protocol. This information then can be used for increase of efficiency of cracking.

The attack called by the researcher of "HTTPS Bicycle Attack" (bicycle attack) allows to determine length of some data transferred in encrypted form: length of heading of kuk, length of the passwords transferred by the POST method, GPS coordinates, the addresses IPv4, etc. At the same time even the traffic which remained in logs gives in to the analysis.

However, to retrieve information on length of fields, it is necessary to foreknow length of some of transmitted data. Besides, attack works only when using the stream cipher.

Having subtracted from authentication heading length length of login, the URL address where the client, and other auxiliary information attacking will become authorized can receive the password length then attack by a trial and error method will become a little more effective.
