No, I was not on a porn site.

I had just clicked on a college baseball website when the ransom note popped up on my screen. Computer froze up completely. I had to restore to factory settings just to get it operating again.

Word of advice...back up your files often. Luckily I backed up all of my critical files earlier this week.

But it's still a pain in the butt.

Anybody know a better way to repair such a situation? Also is there a way to prevent it?

We've been hit at work 4 times.

We backup nightly, but we still lose a lot of money when it hits and folks lose their work since last backup.

What is the payoff to the bad guys who distribute the virus?

No Russian site today or any day for years. I can't remember the last Russian site I went to.

I was on Tigerdroppings and a thread on the Rant got me thinking about likely baseball host sites for the post season tournament.

So, I googled "NCAA baseball regional host site projections." I read articles from a couple of links and when I clicked on the third link, BAM!, the ransom ware message window opened and I was screwed.

To answer the other poster's question, I use McAffee. I just renewed it last week and updated it. Right now I'm obviously not too pleased with McAffee.

If you don't have a recent regular backup, your system may have a recent shadow copy. There's a tool called ShadowExplorer that allows pulling files from a shadow copy. I had to use this method once to recover an infected machine's files at work prior to reformatting because the user that got infected had none of her critical files on her network share.

So you followed the third link "within" a page you found doing a Google search?

Checkout Commvault. It is a great backup option.

I've seen that pop up box more than once. I've always just task manager-ed my way out of it. No problems here.

Macs can get ransomwared too


of course they can. The link you provided though is the only known instance of Mac ransomware. Less than 8,000 Macs were affected total. Symantec found in 2012 that one hacker group was infecting 5,700 PCs per day.

In 2012, Symantec gained access to a command-and-control server used by the CryptoDefense malware and got a glimpse of the hackers’ haul based on transactions for two Bitcoin addresses the attackers used to receive ransoms. Out of 5,700 computers infected with the malware in a single day

I've found some more info. Cryptolocker, the most widely encountered ransomware was infecting 50,000 PCs a month most months and peaked at 150,000 infections in October 2013.

Just because you hit a website that flags your machine as being "infected" does not mean the ransomware was installed.

I just recently had a user land on an infected page while researching brownie recipes of all things

Disconnect the machine from the network
task manager or hard shutdown to end the process
Start up in safe mode and run Av scan
The scan in the case I am speaking about came up clean

We use Applocker on all of our computers and have had 0 infections since implementation.

I cannot stress how amazing Applocker has been for our organization. Highly recommend

Microsoft AppLocker

all i did was link an article stating that Macs are in fact affected by some variants of the same things that affect windows PCs.

i didnt know certain thresholds must be met for it to be relevant

properly implemented application white-listing is one of the biggest wins an organization can have in protecting against malicious code running within their environment

that being said, like any security platform, it can be exploited/by passed.
