Another month, another malware, but the recent bout of CryptoLocker successes has proven half the battle in fighting computer viruses needs to me made by the user, not just the anti-virus software company.
The spread of ‘ransomware’ throughout recent months has seen a massive rise, with the CryptoLocker malware becoming particularly successful.
It holds all the files on youc computer for ‘ransom’, requiring you to pay $300 in bitcoins to release your files. You have 100 hours, and if you don’t pay up, your files are encrypted and there’s pretty much no chance of getting them back.
The ticking clock on the side makes this malware all the more terrifying, and is working in forcing unknowledgable users into paying up. A little bit of good news: paying actually works with this one, the perpetrators seem to be more honest that other malware instigators, but that’s not the point. Users should be aware of preventative measures to stop things like this happening, this all goes to highlight the lack of awareness much of the public has on cybersecurity.
CryptoLocker is spread through fake emails designed to look like they’re from legitimate businesses and fake FedEx and UPS tracking notifications.
Once opened, CryptoLocker installs itself in the "Documents and Settings" folder, scans the hard drive and encrypts certain file types, including documents associated with Microsoft Word and Adobe Photoshop. CryptoLocker then launches a pop-up window with the 100-hour countdown and provides details on how to pay the ransom.

The hackers are covering their tracks by using Bitcoins, a digital currency designed to be as anonymous as cash. Payments are made with a Green Dot MoneyPak, a reloadable debit card.
So, how can you prevent yourself from being hit by ransomware? Follow these tips to keep safe and secure and minimize the risks of your files being encrypted and lost forever.
- Counter-encryption
Encrypt the files you particularly want to keep private, such as documents containing your passwords or personal information, to prevent criminals from reading what’s in them. This will go a long way in keeping your data secure.
- Back-up
Back up your files. If you use an external hard drive, don’t leave it connected to your PC unless you are backing up. Alternatively, pay for an online back-up service – but bear in mind you may still be vulnerable if your backed-up files are mapped as a network drive. Check with your provider if you are unsure.
- Use the Cloud
Create files in the Cloud and upload photos to online accounts like Flickr, Google Drive or Dropbox.
- Go spam free
Change to a spam and and virus-filtered email service. Google Mail, for example, does not allow you to receive or send executable files (that can install viruses) as email attachments, even if they are hidden in zip files. (It also does not allow you to send them).
- No porn
Don’t go to online porn sites, which are often the source of malware downloads. Take care when clicking on adverts; never open Twitter links and attachments from people you don’t know or trust.
- Keep up to date
Make sure your operating system is up-to-date with the latest security.
- Anti-virus
Get reputable anti-virus software and ensure you update it frequently.
