Malware THAT TAKES YOUR FILES HOSTAGE

5 things you need to know about malware that takes your files hostage

1. Online criminals are using our sense of shame to rob us.
According to the F-Secure Labs:

Ransomware’ is a type of malware that attempts to extort money from a computer user by infecting and taking control of the victim’s machine, or the files or documents stored on it. Typically, the ransomware will either ‘lock’ the computer to prevent normal usage, or encrypt the documents and files on it to prevent access to the saved data.

The ransom demand will then be displayed, usually either via a text file or as a webpage in the web browser. This type of malware leverages the victim’s surprise, embarrassment and/or fear to push them into paying the ransom demanded.

Ransomware may arrive as part of another malware’s payload, or may be delivered by an exploit kit such as Blackhole, which exploits vulnerabilities on the affected computer to silently install and execute the malware.

2. It can infect you regardless where you live whether you’re on your PC or mobile device.
The internet erases geography.  If you often install applications from third-party Android markets and happen to download a Trojan:Android/SLocker app, then you can get infected.  If you stay within the official markets then this risk is minimized.

3. Prevention is better than the cure.
Make sure you have updated security protection for all your PCs and devices. Practice good computing habits on your PC and your mobile.

 Be very cautious when installing any application on your device.  Although official markets have served up malware, the risk is minimized heavily. Always keep your phone’s OS and apps up-to-date.

Once a malware is able to encrypt your data, there’s usually very little chance to decrypt them yourself so regularly backup important files with either offline or online/cloud solutions.

4. Once your files are encypted, you probably won’t get them back.
For instance Trojan:Android/SLocker uses AES for encryption, which is a really strong encryption. You can try to use our removal tool but remember number 3.

5. Don’t pay.
Giving into the scheme only encourages the bad guys.

Cheers,

Jason

How about ‘Take Your Work to Kid’ Day?

In the United States, Australia and Canada, April 23 will be Take Our Sons and Daughters to Work Day. But given our changing economy and workplace, is one day enough to improve the bonds between parent and child? Originally created to give girls a chance to "shadow" their parents in the workplaces women have so often been excluded from, Take Your Kid to Work Day, as it's often called, was expanded in 2003 to include boys as a way to help all kids see "the power and possibilities associated with a balanced work and family life." It's a nice ideal, but it isn't much of a reality, at least in many industrial countries. Americans spend an average of 1,788 hours a year at work. Most parents with full-time jobs will spend almost two-thirds of their day working and sleeping, leaving little time for anything else. Hopefully your country is a little better at balancing work/home. Finnish workers, for instance, spent 1,666 hours on average at work in 2013 that's 122 hours or 3 full weeks less than their American counterparts. Don't be jealous: German workers only averaged 1,388 hours at work in 2013. Chances are wherever you live your kids already see you at work. A 2012 survey found that 60 percent of Americans are email accessible for 13.5 hours a weekday with an extra 5 hours on the weekend. Given the extraordinary demands work makes on us, perhaps you can make a demand on your work to be a bit more flexible. Given that we're nearly always accessible, why can't parents plan around their kids' schedules and get some work done? Activities like sports, dance, karate and other arts offer parents a chance to be an active observer of their kids while getting some work done on a mobile PC or device while their children are being supervised by another adult. Given that 70 percent of millennial use their own devices for work, it's likely that younger parents already do this to some degree on their phones and tablets. But they're likely not thinking about potential data leakage that can occur, especially when using public Wi-Fi built on old technology that could expose your identity and possibly even your email. But with security and a virtual personal network -- like our Freedome VPN -- you can be about as secure in the office as you're out in the world seeing how your kids work, as they get another chance to see you.

BYOD

Why Bring your own Device (BYOD)?

Do you ever use your personal phone to make work related calls? Or send work related e-mails? Maybe you even use it to work on Google Docs, or access company files remotely? Doing these things basically means you’re implementing a BYOD policy at your work, whether they know it or not. BYOD – that’s bring your own device – isn’t really a new trend, but it is one that’s becoming more widespread. Statistics from TrackVia suggest that younger generations are embracing BYOD on a massive scale, with nearly 70% of surveyed Millennials admitting that they use their own devices and software, regardless of their employer’s policies on the matter. This is essentially pressuring employers to accept the trend, as the alternative could mean imposing security restrictions that limit how people go about their work. Consequently, Gartner predicts that 38% of businesses will stop providing employees with devices by 2016. It kind of seems like workers are enforcing the trend, and not businesses. But it’s happening because it’s so much easier to work with phones, tablets, and computers that you understand and enjoy. Work becomes easier, productivity goes up, life becomes more satisfying, etc. This might sound like an exaggeration, and maybe it is a little bit. BYOD won’t solve all of life’s problems, but it really takes advantage of the flexibility modern technology offers. And that’s what mobility should be about, and that’s what businesses are missing out on when they anchor people to a specific device. BYOD promotes a more “organic” aspect of technology in that it’s something people have already invested in and want to use, not something that’s being forced upon them. But of course, there are complications. Recent research confirms that many of these same devices have already had security issues. It’s great to enjoy the benefits of using your own phone or tablet for sending company e-mails, but what happens when things go wrong? You might be turning heads at work by getting work done faster and more efficient, but don’t expect this to continue if you happen to download some malicious software that infiltrates your company’s networks. You’re not alone if you want to use your own phone, tablet, or computer for work. And you’re not even alone if you do this without telling your boss. But there’s really no reason not to try and protect yourself first. You can use security software to reduce the risk of data breaches or malicious infections harming your employer. And there’s even a business oriented version of F-Secure's popular Freedome VPN called Freedome for Business that can actually give you additional forms of protection, and can help your company manage an entire fleet of BYOD and company-owned devices. It’s worth bringing these concerns to an employer if you find yourself using your own devices at the office. After all, statistics prove that you’re not alone in your concerns, and your employer will most likely have to address the issue sooner rather than later if they want the company to use technology wisely.
