Experts have discovered another modification of Stuxnet
Despite all attempts by network security experts to find a reliable means of dealing with the Stuxnet worm, this task is not yet feasible. Moreover, new versions of Stuxnet are found that work with different types of control systems than the versions of the worm that were previously detected. Experts have discovered another modification that can work on the control equipment of frequency converters.
Ha Habré more than once and not two said that Stuxnet affects primarily industrial systems, as a rule, the control systems of the SCADA class, which are manufactured by Siemens. These systems are managed by Windows, the vulnerability of which uses Stuxnet. As usual, one of the main factors for the spread of this worm is the "human" factor - Stuxnet penetrates the system from an infected flash drive. Of course, it is impossible to control all, without exception, employees who have access to such equipment.
It is worth recalling that computer security experts believe that this worm was created not by one or two lone hackers, but by a whole group that may be controlled by a whole state or by a powerful government organization. Earlier it was claimed that this worm was “sharpened” under the systems that are used in Iran, but it seems that such an opinion did not long remain popular.

The found Stuxnet version works on frequency converters, which are used, for example, in uranium enrichment systems. It is clear that such systems are very important, and disruption of such systems can be fatal for the entire uranium enrichment cycle. The types of converters, in the systems of which a new modification of Stuxnet is found, are used in Iran and Finland, probably there are other countries that work with this type of equipment.
Computer security experts believe that not all versions of Stuxnet have yet been compiled, and when this happens, it will become clear what this malicious software is intended for. So far, experts have been guessing. Yes, some believe that the worm serves to disrupt the operation of the nuclear complex in Iran, but so far not many experts agree with this opinion.
It remains to wait until all members of the Stuxnet family are found - perhaps then we will know what the real purpose of the worm is.
