Bluetooth security vulnerabilities are reported


Webroot is warning users of the risks of Bluetooth devices as possibly attracting hackers, as in this article   Webroot advises users to turn off devices when not in use.  This appears to apply to wearable devices, which could provide a portal for hacking personal information from phones.

  

I’ve noticed that the Microsoft Action Center, on at least one computer, recommends resinstalling a Bluetooth driver after the Creators’ Update of Windows 10.  But there don’t seem to be any symptoms.  I wonder if this relates to the same possible vulnerability.

Phishing scam tells you your Facebook account is suspended


Here's the most recent phishing scam.  You get repeated emails telling you to restore your Facebook account with one click.  It comes from "facebookmail dot com".

So just log in to Facebook yourself and check for yourself.  

Another scheme is to misspell Facebook and take you to a survey page.

More sophisticated phishing scheme pretends to warn of invalid overseas iTunes purchases


There is a clever phishing scheme now where the attacker sends an email that purports to be from Apple advising you of an overseas purchase of a game from iTunes for about $50.  There is a PDF of the receipt and a link to challenge it.  Previously, there may have been another email without attachments advising of the purchase. If you run the cursor over the sender, it doesn't have Apple in the domain name.

This scheme is a little more complex than a lot of them.  You can forward it to "reportphishing" at apple.com

More concerns about Kaspersky and Russia in NY Times


The New York Times has an article today, “The Cyber Insecurity Company”, or with online title, “The Russian company that is a threat to our security”.  That’s Kaspersky Labs.

Best Buy and Geek Squad today favor Trend Micro, but before they have bounced between Webroot and Kaspersky. But the article notes that companies that use Kaspersky will have their networks exposed to servers in Russia.


That probably doesn’t matter to home users, no matter how paranoid you are about Putin or Ukraine or Chechnya.  But it would matter to most international companies, or to anyone that keeps user PII on his servers. 


DOD is no longer allowed to use Kaspersky.
