Oracle (and Java) delenda est

In case you haven’t seen, there’s a terrible unpatched vulnerability in Java right now that baddies are using to install randomware on PCs. Then, this morning, I saw that Oracle has known about this vulnerability since August, and hasn’t bothered to fix it properly yet. That should be criminal negligence, but the rules are different for billionaires.

Of course, I’ve been saying for ages that we’d all be better off if we just uninstalled Java completely, but I know very few people who’ve done it, out of fear they’ll break something. (Those same people often refuse to patch Java, out of the same fear.) I was trying to figure out why anyone would want to run Java these days anyway, and then I saw this quote, via David Huff:

“Given a choice between dancing pigs and security, users will pick dancing pigs every time.”  –Edward Felten and Gary McGraw

That explains everything. Java is exceptionally good at making animated dancing pigs.

All of the major sites are recommending that you disable Java in your web browser. I continue to recommend just uninstalling it entirely, since Oracle is more interested in dancing pigs than in security.

Mobile malware is coming. Get prepared.

One thing I’m seeing in the predictions-for-2013 columns is that mobile malware is going to increase this year. While I can’t be certain it’s going to happen, all of the ingredients are there. The only thing stopping it is motive.

I’m familiar with Avast antivirus on Android. It’s nice. Whenever I download an app from the Google Play store, it scans it, and if it finds something it doesn’t like, it intervenes. Read more

How to schedule scans with Avast (even the free version)

Scheduling scans with Avast is easy, as it turns out, if non-obvious. Launch Avast, then, non-intuitively, click Scan Now. Click Settings, then, buried on the left is an option called Scheduling.

I recommend doing a quick scan at least once a day and a full scan at least once a week. If you’re using Avast as a secondary scanner, be sure to have your primary scanner scheduled to perform scans too. Read more

Get defense in depth with antivirus by installing Avast as a secondary scanner

Two antivirus programs on one system? Heresy, right?

Well, not if one is designed to play second fiddle. As it turns out, Avast, one of the best free antivirus programs, can do just that. Just download it, run the installer, and pick the second option–“Compatible install – install as the second line of defense.” Be sure to de-select the option to install Google Chrome and make it your default browser, unless you want that. Free programs often come with ridealongs.

8-character passwords are obsolete

In case you missed it, a researcher has built a system that can crack every possible 8-character password in less than six hours. 8-character passwords are obsolete.

If he’s got it, so do the bad guys. Read more

Workable two-factor authentication

I’m several months late to this party, but I just saw Marcel’s post on Google’s two-factor authentication with a smartphone.

He’s right. It works until someone steals your phone. Once someone steals your phone, you’re in a world of hurt. It’s just a compromise, until we find a way to do two-factor authentication the right way.

The right way is with a smartcard, issued by some sort of central authority. Read more

Ars Technica: 64-bit Firefox on Windows needs to be a priority

Ars Technica said yesterday that Mozilla needs to make 64-bit Firefox on Windows a high priority. I agree with this completely. With web browsers, you can’t have too much security, and Firefox on Windows is a big target.

Reduce your RAID failure rate

It’s not often that you end up talking about computer hardware at church. It’s especially not often that you end up talking about a RAID failure at church. But one such conversation got me thinking again about ways to reduce RAID failure rate.

This past Sunday, I talked with the executive director, who told me five of the drives in the 8-drive RAID array failed all at once. “That’s not supposed to happen,” he said.

It isn’t. But I know why it did.

Dvorak is wrong about the cyber war

So John C Dvorak (I’ll call him John Dvorak because he hates it–John Dvorak John Dvorak John Dvorak) says that cyber warfare, like Y2K, is a bunch of hooey.

I lived through Y2K, and I’m fighting the cyber war. He’s wrong on both counts. Read more

How to encrypt PDF files for free

Yesterday I wrote about the importance of encrypting documents before you send them via e-mail. But what if you don’t have a PDF creator, other than Microsoft Office or Open/Libre Office?

It turns out you can encrypt PDF documents, including those you create with office software, for free–with caveats.
