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.

The recent statements from FBI director James Comey is yet another example of the authorities’ opportunistic approach to surveillance. He dislikes the fact that mobile operating systems from Google and Apple now come with strong encryption for data stored on the device. This security feature is naturally essential when you lose your device or if you are a potential espionage target. But the authorities do not like it as it makes investigations harder. What he said was basically that there should be a method for authorities to access data in mobile devices with a proper warrant. This would be needed to effectively fight crime. Going on to list some hated crime types, murder, child abuse, terrorism and so on. And yes, this might at first sound OK. Until you start thinking about it. Let’s translate Comey’s statement into ordinary non-obfuscated English. This is what he really said: “I, James Comey, director of FBI, want every person world-wide to carry a tracking device at all times. This device shall collect the owner’s electronic communications and be able to open cloud services where data is stored. The content of these tracking devices shall on request be made available to the US authorities. We don’t care if this weakens your security, and you shouldn’t care because our goals are more important than your privacy.” Yes, that’s what we are talking about here. The “tracking devices” are of course our mobile phones and other digital gadgets. Our digital lives are already accurate mirrors of our actual lives. Our gadgets do not only contain actual data, they are also a gate to the cloud services because they store passwords. Granting FBI access to mobile devices does not only reveal data on the device. It also opens up all the user’s cloud services, regardless of if they are within US jurisdiction or not. In short. Comey want to put a black box in the pocket of every citizen world-wide. Black boxes that record flight data and communications are justified in cockpits, not in ordinary peoples’ private lives. But wait. What if they really could solve crimes this way? Yes, there would probably be a handful of cases where data gathered this way is crucial. At least enough to make fancy PR and publically show how important it is for the authorities to have access to private data. But even proposing weakening the security of commonly and globally used operating systems is a sign of gross negligence against peoples’ right to security and privacy. The risk is magnitudes bigger than the upside. Comey was diffuse when talking about examples of cases solved using device data. But the history is full of cases solved *without* data from smart devices. Well, just a decade ago we didn’t even have this kind of tracking devices. And the police did succeed in catching murderers and other criminals despite that. You can also today select to not use a smartphone, and thus drop the FBI-tracker. That is your right and you do not break any laws by doing so. Many security-aware criminals are probably operating this way, and many more would if Comey gets what he wants. So it’s very obvious that the FBI must have capability to investigate crime even without turning every phone into a black box. Comey’s proposal is just purely opportunistic, he wants this data because it exists. Not because he really needs it. Safe surfing, Micke
Is this China's digital riot police? A "particularly remarkable advanced persistent threat" has been compromising websites in Hong Kong and Japan for months, according to Volexity. The pro-democratic sites that have been infected include "Alliance for True Democracy – Hong Kong" and "People Power – Hong Kong" along with several others identified with the Occupy Central and Umbrella Revolution student movements behind the massive protests against the Chinese government. Visitors to the sites are being targeted by malware designed for "exploitation, compromise, and digital surveillance". In an analysis on our Labs Blog, Micke notes that it's possible that cybercriminals could be simply piggybacking on the news without any political motivation. However, the Remote Access Trojans (RATs) being used could provide serious advantages to political opponents of the movement. "A lot of the visitors on these sites are involved in the movement somehow, either as leaders or at grassroot level," he writes. "Their enemy could gain a lot of valuable information by planting RATs even in a small fraction of these peoples’ devices." And even leaders aren't compromised, the publicity around the attack will drive users away from the sites. This is a tactic that would definitely benefit those who want these see protests to end ASAP. And it would be a far more effective tactic if not for social networks like Twitter that can be accessed to plan resistance,even if the government blocks them -- as long as you have a VPN solution like our Freedome. If the goal is to cripple the protests by targeting protesters, "you don’t have to be a genius to figure out that China is the prime suspect," Micke writes. The significance a state-sponsored RAT attack -- or even a state-condoned attack carried out by privateers -- would be immense. Criminals use malware to target individuals, businesses and governments themselves. Government-sponsored cyberattacks on citizens practicing civil disobedience could be considered an escalation beyond even likely government-sponsored surveillance malware like Flame, which forces businesses to consider malware attacks from their own governments. Over the last year we've learned just how far suspicious governments will go to play defense against internet users who haven't been accused of any crime. Now we're seeing hints that a government may be willing to play offense too.
Yet another massive user ID and password leak. This time it affects about 7 million DropBox users, even if DropBox denies they were hacked. As usual, such a hack means that the data these users have stored in DropBox is in jeopardy. It also means that those who use the same ID and password on many services have much bigger troubles. Let’s see what we can learn from this: Always use unique passwords on the services you use. This does not prevent password leaks, but it limits the damage when a leak occur. (A password manager you trust makes this much easier.) Be alert and change your password as soon as you hear about a leak like this. Right now, we don’t know which users are affected. But if you have an old and weak password, it’s a good idea to change it NOW anyway. Changing it one time too many is better than having your confidential data all over the Internet. Pay attention to the security-awareness of the cloud providers you use. This may not have been DropBox’s fault, but it could have been. This is a good opportunity to mention our own younited, which is built with security in mind from the ground up, and is located in a country where the authorities doesn’t do mass surveillance. BTW, Edward also thinks you should consider alternatives to DropBox. DropBox claims this leak happened in some other service that connect to DropBox. This is a plausible explanation and reminds us about the danger of connecting services to each other. If you enter the password of any service into another service, you must ask yourself two questions. Will this company refrain from misusing my data and does this company protect my password sufficiently? By replicating the password to several places you increase the risk that it leaks out. Don’t do that unless you get a significant benefit and trust all places where the password is stored. Two-factor authentication is a great feature that increase security. Use it whenever possible. It should by now be clear that this kind of massive password leaks aren’t rare incidents. We see a constant stream of these and there are probably many leaks that remain unnoticed, or are noticed but stay out of the headlines. We all have to realize that a leak like this will hit us sooner or later. Sorry for sounding like a broken record, if you still have the same password on several services, you should be busy changing them by now.
