Why you shouldn’t use the ‘firewall’ that your ISP gives you? More than 4.5 million DSL modems attacked and breached, resulting in viruses and stolen information.

Uncategorized
Just this week (or was it last week?) I was asked again by a client why he needed to purchase a firewall when his ISP was going to give him one for free.  This can sometimes be a difficult thing to explain to someone trying to get the most bang for their IT buck and their ISP is telling them that they're getting a 'firewall' for free (while their IT guy is trying to sell them one) but the fact is, you need one.  There are several reasons (most are noted on the US CERT website) but the one that we're going to focus on here is the easy one, they aren't secure.  The device that you get from your ISP is a device that they can / will 'manage' for you.  They…

October 2012 Patch Tuesday

Uncategorized
October will see seven bulletins from Microsoft, one addressing a vulnerability listed as critical in Microsoft Office and Windows Server, nothing (yet) from Adobe since APSA12-01 and Java will have it's 'regular' update, currently scheduled for 16 October (it's been eerily quiet from the Oracle camp lately).  There are a few other noteworthy items this month that I will covering in additional articles.   Microsoft Microsoft released 7 bulletins this moth including 1 critical and 7 listed as important.  The critical bulletin addresses a vulnerability in Microsoft Office and Windows Server.  The vulnerability in Office seems to be being downplayed a bit, noting that it 'only really affects Word 2003, Word 2007 and Word 2010'.  The downside though is that it can allow remote code execution and I really don't know that many folks…

New virus, undetected by many antivirus products

Uncategorized
In the past 2 days, we have noted a number of 'questionable' files that weren't flagged as being a virus or malware but exhibited behavior that led us to believe that they were.  We submitted samples to ESET and received the response below this morning.  I suspect that the signatures will make it's way into most major antivirus products by days end but, until that time, you may be left unprotected.  We have been able to get these files through gateway security devices, email malware scanners and local antivirus scanners, even running explicit scans on the files.  They files have been delivered via email as Airline tickets (claiming that we purchased them) and UPS and USPS tracking information.  If you receive any such notifications, please confirm that the reported sender…

Did someone that you know just lose their computer guy? Be a hero and recommend Cyber Tech Cafe :)

Uncategorized
In the past 3 days, we've had a number of folks tell us that they or someone that they know is 'losing their computer guy' and wanted to know what we did and if we may be able to take over.  I wanted to take a moment to confirm that we are accepting new clients and give some quick details about what we do / can do:   - Residential computer support - Customers can drop computers by our shop on Main Street in Cartersville for repair or we can come on site.  We can take care of anything from hardware repair and upgrades, software installation or just basic tune-ups (which are $35 and typical turn around is 2 to 3 day)   - Business computer and network support -…

October is National Cyber Security Awareness Month

Uncategorized
October is National Cyber Security Awareness Month.   Ok, before you get the glazed over eyes, bear with me a minute here.  This is going to be another of those 'you should do your updates' posts, but my hope is that it's also a reminder of the seriousness of [a lack of] security on your personal computer.  One thing that we hear over and over is something like 'Oh, I don't do my banking online, so I'm not too worried about it'.  The truth is though, attackers rarely want the $12.00US that you've managed to amass in your checking account (or the $13.00US that you've been able to scrape togeher in savings), they want to use  your computer to rip other folks off, or to host child porn, or to…

New vulnerability in Java could impact 1 billion computers

Uncategorized
According to this article, Security Explorations has identified a new vulnerability (they are calling it a zero day but, as I understand it, it's just a proof of concept at this point) in the latest version of Java.  There's ample detail in the linked story but I wanted to touch base on just two key points: What does this mean for me?  Basically, if you have Java installed on your computer, even the latest version, an attacker can create a program that, when you run it, will give the attacker the ability to control your computer with the same rights and permissions that you have.  If you are a limited user, the attacker will be able to operate as a limited user.  If you are an administrator on your computer (or…
