JAVA Warning

News, Warnings | Posted by Dennis July 12th, 2012

UPDATE YOUR JAVA.  I’ve cleaned up two very nasty PC infections this week that were Java-based viruses.  BOTH had current anti-virus protection, which didn’t stop the attack.  When Java updates, it’s usually to patch some security hole or other issue.  The hackers and Bad Guys know this, and will exploit any software to take over your computer.  If you’re not sure if you’ve got the latest, click here to get the most recent version.  WARNING: this install will try to get you to add the Ask Toolbar.  Watch for the option and uncheck the box if you don’t want it. 

Presidential Dilemma

News, Warnings | Posted by Dennis June 6th, 2012

Well, the cat is OUT of the bag.  A while back there was a worm called Stuxnet that was discovered to be hiding on PC’s across the planet, apparently doing, well… NOTHING.  It had very sophisticated code, but no one could tell exactly what its purpose was.  Finally it was revealed that this critter had been released to slow down Iran’s nuclear program.  60 Minutes on CBS featured an article about it, revealing that it worked on industrial controls, and targeted the centrifuges that Iran uses to purify Uranium and Plutonium.  Now it has come to light that the US was, indeed, the source of that bug.  It started with Bush in 2006, and continued with President Obama.  It took guts for both of them to authorize this –  the implications are staggering.  We have officially entered a world where digital warfare is reality.  Although it saved lives in terms of immediate human casualties, these presidents opened a virtual Pandora’s Box in authorizing this attack.  See, the worm has a blueprint for taking over and altering controls in facilities like the Iranian Enrichment plants.  But these are the same controls that are used EXTENSIVELY across the US.  So the weapon could give our enemies the ability to attack critical infrastructure like power plants and water facilities.  Was it worth it?  Well it seemed to work, so it bought them a little time.  But the decision to use it could very well turn out to be more detrimental to the USA than any benefits that were gleened.  Time will tell.  Kudos to Symantec for isolating this critter, and the New York Times for covering a great story about war in the next millennium.  You can find the full article here. 

9/11 Backlash

News, Warnings | Posted by Dennis September 11th, 2011

On this 10th anniversary of the 9/11 terrorist strikes, I felt it necessary to inform you, the readers, of the abuse that resulted.  Keep in mind that we KNEW.  We HAD THE INTELLIGENCE needed to stop the attacks.  And yet, afterwards the (Busch) administration passed SWEEPING laws that not only invaded your privacy, but are UNCONSTITUTIONAL.  You have the right, for example, to face your accusers.  To know what lists you may be on, and who is tapping your phone, or looking at your phone bills.  But not any more.  Obama promised he’d stop the nonsense.  He didn’t.  So we go on, allowing every citizen’s rights to be violated daily.  Is it helping?  Evidently not, from the reports I’ve seen.  We are spending $BILLIONS more on Homeland Security, yet the result seems to be more confusion than before.  It’s pretty sad.  I think that those who gave their lives on that fateful day would be pretty let down, to say the least.  Here’s an article with more details. 

Denial of Service (DoS) attacks

News, Warnings | Posted by Dennis August 17th, 2011

Denial of Service AttacksIn a previous post I described BotNets and zombie PC’s, and a customer asked me ‘Why would they do this?’.  The main reason is to have a virtual ARMY of computers, spread across the globe, to do your bidding.   This way, if the person(s) responsible wants to take down a web site, they can.  They flood the site in question with so many requests at the same time that the site goes down (or at least slows to a crawl).  It’s difficult to stop because the traffic is coming from so many different places.  There are many types of DoS attack, this one is called Distributed, or DDoS.  One of the most worrisome examples of this type was the July 2009 cyber attack on the US and South Korea, allegedly spawned by China and North Korea.  You can read the details here.  IT and network professionals are always watching, tweaking, and learning to prevent these types of vulnerabilities.  It’s a constant battle between the good guys and the bad guys. 

Attacks from Russia

News, Warnings | Posted by Dennis May 23rd, 2011

Ok, so the source of the latest digital attacks has been revealed!  They are using Google API to steer people to infected sites.  The source is in Russia.  This was verified by a customer who inadvertantly gave their CC number to the critter (the one that pretends to be Antivirus), then contacted the bank.  They rejected the charges based on location.  So it seems that the Russian mob has found another way to steal lots of American money.  IF I DISAPPEAR PLEASE TELL THEM TO READ THIS!  😉   I’d say avoid Google searches altogether until they clean up their act.

Don’t panic

Helpful Hints, Warnings | Posted by Dennis October 5th, 2010

If you get attacked while surfing (e.g. a window pops up saying you are infected – that IS the infection!) Just press CTRL-ALT-DEL and run task manager. Click on every browser window that’s open and choose END TASK. I’ve had this happen several times from Google results.

Sage Advice

Warnings | Posted by Dennis October 3rd, 2010

Ok, so this is something all my friends, family, and clients need to know: I clean up virus/trojan/malware attacks every day. Lately, the vast majority are coming from the social networking pages like MySpace, Facebook, and YouTube. Maybe you caught the irony – check out all the icons below for a complete list of such sites LOL. Anyway, there are some standard things you can do to prevent getting “infected”. 1) MAKE SURE you have good virus protection! 2) NEVER click on stuff from people you don’t know/trust (i.e. don’t take candy from strangers!) and 3) keep your browsers and software up-to-date. But here’s a special one: If you like to check YouTube videos often, WATCH OUT FOR FRESH ONES!! If the video has only been up for an hour, it could be an infected one that some hacker has dropped. I’ve caught ’em doing this with infected videos for about an hour, then they take ’em down to keep from getting caught
