Microsoft Windows Support Phone Scam

In Uncategorized on March 28, 2016 at 3:54 pm

“This is Microsoft Support”
telephone scam – Computer ransom lockout

  1. You receive a call from someone (usually with a Foreign accent) that identifies him/herself as a member of Microsoft Support or Windows Support team.
  2. They’ll inform you that your computer is infected and sendout viruses and  you have a number of critical problems with your PC and that you will need to have it fixed.
  3. To convince you, he offers to connect remotely and pulls up your Event Log (eventvwr.msc).  He then filters for Warnings, Errors, and Critical events and uses that as evidence that your PC will soon fail to work correctly if you do not pay him to correct it.

The astute among you have probably already sensed that something here is seriously wrong, and it’s not your PC. It’s the fact that someone is calling you to tell you there is a problem with your computer. No one will ever do that. The only way they could possibly know there is a problem is by hacking or guessing.

In this case, it’s mere guesswork, and it’s not even correct most of the time. The Event Log is supposed to log warnings and errors, and even on the healthiest of PCs there are plenty of Error Events that can be safely ignored, as they often don’t amount to anything. The important thing to remember is to never trust someone who calls you about a problem with your PC, and never, EVER let them connect remotely to your PC.

If you do make the mistake of letting them connect, but then you happen to get cold feet and refuse to pay the $180+ they request via credit card, the next thing that happens isn’t pretty. This scammer proceeded to actually follow through on his promise of the PC “not working” if they don’t agree to have him fix it, and so in a few quick steps, behind the user’s back, he enacted what is known as SysKey encryption on the SAM registry hive.

SysKey encryption is a little-known feature of Windows which allows administrators to lock out access to the Security Accounts Manager (SAM) registry hive so that login specifics cannot be stolen and the PC cannot be accessed without knowing the proper credentials. The problem is, unlike other scams, there is no way around the problem; you can’t simply remove the password, as the actual SAM hive has been encrypted entirely by the process. If your Windows installation has had SysKey activated, you’ll see the following message:

Startup Password

This computer is configured to require a password in order to start up. Please enter the Startup Password below.

The window which appears looks like this:

This computer is configured to require a password in order to start up. Please enter the Startup Password below.

Java flaw draws…

Java flaw draws Web attacks

Java flaw draws Web attacks, reports say

A vulnerability in the Java software has the potential to affect a wide swath of computer users, and researchers warn that it’s already being exploited “in the wild.”

Security researchers have spotted a new vulnerability in the widely used Java softwarethat could give attackers access to your computer.

The US-CERT group today issued an alertsaying that Java 7 Update 10 and earlier versions of the software contain an unspecified vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code. The attack can be induced if someone visits a Web site that’s been set up with malicious code to take advantage of the hole.

This weak spot is already being attacked “in the wild” — that is, it’s a real-world threat — and is being incorporated into exploit kits that make it easier for those with ill intentions to create an attack.

Java supplier Oracle has yet to issue a fix for the vulnerability, so researchers are advising users to disable Java for the time being.

The zero-day vulnerability was reported to US-CERT by a blogger named Kafeine at the siteMalware don’t need Coffee. The exploit has been confirmed by AlienVault Labs, which also was alerted to the matter by Kafeine, and by BitDefender, according to a report in Computerworld.

We’ve reached out to Oracle for comment and will update this story when we hear back.

Defeating Keyloggers
LogOnFixIt Users,

Security is knowing how to stay safe. It can also be information you can use to improve your life or standard of living.

In our case, at Sunbelt Security News it is providing you with the knowledge to protect your computer and family and information. This is our job as we see it. Our goal is to see that you have the necessary tools to take care of “business”, and we always are interested in your input.

Lately many of you have been concerned with Keyloggers, the practice of logging keys as you touch them on the keyboard. It is often done for nefarious purposes like capturing passwords and other vitally important information. I talked our Support Manager, Mike Williams on how to defeat these buggers. Check it out in “Dirty Tricks”.

Also in Dirty Tricks is some valuable information about the recent outbreak of spam that appears to come from your own email address. It seems that there has been some hacking going on.

I Am the Patchman

Today being the second Tuesday of the month, means it is ‘Microsoft Patch Tuesday’. Per Microsoft, there will be 13 updates and fixes, eight of them critical. You may have been hearing about some vulnerabilities in Adobe especially Reader and Acrobat which puts PDF files at risk. Patches are scheduled for today for those products so make sure you get them. If you have your PC set for automatic updates, they will be installed by themselves. If you have not, in many cases you will see a new yellow shield in the bottom right task tray. Make sure to click on that shield and install the updates. If you do not see the yellow shield, make sure to go to the windows update site and let Microsoft update your PC. This is free, but you have to run Internet Explorer when you do this, and you may need to install an add-on via the yellow bar at the top:

Should I Leave my computer on at night?

To power off or not?

There are several factors at play here. They include the following:

  • There is virtually no power-saving advantage to powering off your CRT monitor. The energy consumed to keep your tube warm may extend the life of the monitor itself and in the end may save the University more by leaving it on.
  • If your PC is managed:
    • You are better off leaving it on as operating system patches will be delivered to you overnight and your PC will be patched by morning. If you power it off patches will still be delivered but not applied until the next scheduled application time. In Academic Support this is 5am the next morning.
    • In terms of Virus Protection, you are again better off leaving your PC on. Virus definitions will arrive overnight and a full scan of your PC will happen at that time. If you power it off you will still receive virus definitions when the PC comes up, but you will have missed the scanning window and have to wait until the next scheduled scan. If this time is again at night time, your PC may never actually get scanned.  To make matters worse, if you turn off Real-Time Scanning, (the feature that scans a file when it is opened) you could easily be infected.
  • If your PC is client managed (meaning you manage it yourself):
    • Obviously the sooner you patch your operating system the more protected you are from viruses and hackers that will take advantage of it. Windows XP has the ability to automatically do Windows Updates. If this is not utilized do manual updates on a regular schedule. Since you are choosing the method and the schedule you are the best one to decide whether-or-not to leave your PC powered up.
    • The same is true of anti-virus updates. Choose a schedule that best suits your work schedule and make sure your PC is powered on then it is scheduled.
  • Some hardware like Hard Disks fail less when they are never powered off. There may be a hardware cost associated with powering your PC every night.
