Cryptolocker: Why Modern Computer Viruses Are More Dangerous Than Ever

crypt-messageToday’s computer viruses go beyond mere annoyance. How does holding your data for ransom sound? What about spying on you through your webcam, tracking your physical location, recording every keystroke you make? Welcome to the modern generation of computer threats, where infection means real-world consequences.

The latest virus making the rounds is Cryptolocker, a textbook example of all the truly nasty ways in which a modern computer virus can ruin your day. Cryptolocker encrypts your data with a one-way algorithm which mathematically cannot be reversed. If you don’t pay the ransom within the timeframe, the only key to your data is gone, kaput, goodbye.

You can’t restore your data by removing Cryptolocker, because removing the virus doesn’t decrypt the data. No tech support person in the world can decrypt it for you because it’s simply not possible without the key. Even police departments have paid the ransom, even as they recommend that consumers not do so.

Here are some resources on Cryptolocker so you can keep it from digging its sharp claws into your computer.

Cryptolocker started its initial spread via email attachments, which are fairly easy to avoid. But now it’s morphing into variants that can be transmitted via USB drive, and luring victims with fake software activation codes. Although it’s a Windows virus, like all viruses it can be transmitted via Macs and mobile devices. Following in the steps of other viruses, soon Cryptolocker will evolve into spreading via social media sites.

And this is just the start.

There are other viruses out there that can activate webcams – and yes, they can bypass the green light that tells you the webcam is on. They can listen through microphones. They can track your location via your mobile device. They can listen in on your conversations on social media.

Now, more than ever, it’s vital to protect yourself from computer viruses. Here are some Tech Tips resources to help:

How To Protect Your Privacy On Social Media Sites Like Facebook And Twitter

socialmediaWhen was the last time you checked the privacy settings on your social media accounts? Once? Twice? Never? If you don’t check periodically, you run the risk of having your account hijacked by hackers.

What do you mean by “social media”?

Sites primarily used as a means of mass communication: Facebook, Twitter, LinkedIn, Pinterest, Instagram, Tumblr… You could also think of them as virtual communities, each with different rules and tendencies.

Why should I bother securing my social media accounts?

Because having your account hijacked stinks. At best, it’s inconvenient to reset your passwords and notify your friends. At worst, it results in data loss, identity theft, and financial ruin.

But aren’t these sites private?

Nope. They have privacy settings, most of which aren’t on by default. But anyone can sign up on these sites, and anyone can pretend to be anyone else on them. They’re designed to share information, not keep it private. Which is why the idea of people sharing their entire life stories and that of their kids gives me the screaming heebie-jeebies. Social media sites aren’t private photo albums and diaries. They’re publicly-accessible news sites (and data aggregators for advertisers).

Why do hackers want to hijack me?

In short: money. Cybercrime is a multi-billion dollar global industry. With economies tanking and people out of work, the idea of making tons of cash through Internet scams is hard to resist. Through commandeering your account, cybercriminals sell everything from Internet pharmaceuticals to fake antivirus programs to Twitter followers using your hijacked identity. It’s the go-to crime of the 21st Century.

Should everyone protect their social media accounts?

Yes. Absolutely. There’s no excuse not to.

How can I protect my social media accounts?

Use strong passwords that are unique on every site

Double-check your privacy settings

Report fake followers and inappropriate content

Verify links before sharing
