Do not intrude in my devices

Spam

"I am not overlooking any mail. I'm looking at all of it. I even wrote back to the Viagra people”. For sure many of you do not have much patience as the songwriter Randy Newman when you face your email inbox. Or... do you belong to those who respond to spam?

Spammers manage to bypass spam filters using different tricks, but it seems that amount of spam has dropped by 3.4% in the third quarter of this year compared to the previous one and 4 out of 100 contained malicious attachments, according to security firm Kaspersky's report. More than a half of those emails that we haven’t requested come from China, USA and South Korea.

However the spam is not the only type of interference that user have to cope with. Some extensions that you sometimes install in your browser could change your browser settings at their will. Google tries to solve this problem blocking extensions not provided by the Chrome Web Store for Chrome for Windows.

Talking about the invasion of our devices, we can not leave out the rumors that there is a virus called *BadBIOS, capable of being transmitted through ultrasound,* that is, it would be able to infect other computers through speakers. It is just a rumor, but it gives us a clue about where threats could come from.

Can you imagine the intelligence services using these techniques? Nothing could stop them! People from Brazilian intelligence services who made the surveillance on foreign diplomats in Brasilia some years ago could not even dream about it, for sure.

Regarding the past, have you ever heard about Silk Road? This is one of the largest illegal business organizations in the world working under Tor network. The FBI arrested its founder, and the organization closed, but now it is back under the direction of someone who has picked up the baton.

An advisory before getting to the end to this article: Cisco has released free updates to fix a problem on the implementation of SIP (Session Initiation Protocol) in some versions of Cisco IOS your system.
