Skype under attack.

Thank you so much! Yes, you cannot hide from the eye of Big Brother!

It's a shame that skype was not safe.

Encrypted, as in situations with sostovymi and social. networks. Left-wing users or legend for a real person.

This is of course very sad, but inevitable, at least for us.

Well, I don’t know, at least the GB has no technical ability, I constantly communicate with them through Skype.

Skype: I know where you are and what you download

Skype: I know where you are and what you download

Scientists have developed an inconspicuous and inexpensive way to track the IP addresses of tens of thousands of Skype users and associate this information with their online activities, such as file sharing via BitTorrent.

The method, which is presented in a recently published scientific article, works even when users set up their Skype accounts to receive calls only from people in their contact list. It also works against Skype users who are currently out of the system, provided that they have used the VoIP program in the past three days. The technique allows you to associate an individual Skype user with a special BitTorrent activity, even if he shares with others the IP address on the local network that uses NAT.

"We have demonstrated that it is possible for an attacker with few resources to determine the current IP address of the selected Skype user (if the user is currently active)," the article says. "In the case of Skype, even if the user selected by the target uses NAT, the attacker can determine the public IP address of the user. Such an attack can be used to realize many malicious purposes, including monitoring the movement of a person or establishing an identity connection using the Internet."

Scientists have found that it’s fairly easy to find the ID of most Skype users when their email addresses and names are known to the attacker. Additional information, such as the city in which the victim lives, his gender or age, provides the best performance for the task.

Then, using a customized system that sends modified, specially formed packages, a call is made to the selected Skype account. By examining the headers of the returned data, attackers can easily determine the person’s IP address. Since scientists do not establish a full connection with the victim, she does not realize that the Skype account is being monitored. Scientists have designed the system in such a way that it can track 10,000 people somewhere for $ 500 a week.

After studying the IP addresses of individuals, scientists turn to BitTorrent sites to track the download addresses in their database. Even if one of the IP addresses was common for many users on the same network, the method allows you to establish a connection with a specific Skype user by downloading, and, among other things, collect identifiers from BitTorrent networks known as info hashes.

Scientists said that Google Talk, MSN Live, and other real-time communication applications might also be vulnerable to this technique, but they singled out Skype for having the “largest privacy vulnerability.”

Adrian Escher, Director of Information Security at Skype, made the following statement: “We value the privacy of our users and consider it our duty to make our products as secure as possible. As with typical Internet communications software, Skype users, those who establish the connection can determine each other's IP addresses. During research and development, we will continue to improve our software. "

A research article entitled "I Know Where You are and What You are Sharing" provides some suggestions for improving Skype's ability to hide the identity of its users.

"One of the solutions that will take a long way is to develop a VoIP system so that the IP address of the called person is not disclosed until the user accepts the call," the article reads. “In this situation, Alice will not be able to discreetly call Bob. Moreover, if Alice is a stranger (not on Bob’s contact list) and Bob sets up his client so that he does not receive calls from strangers, this will prevent him from being tracked by strangers in any way.
