Almost every day a new Trojan or Ransomware is discovered. They disable your mobile phone so that criminals can get hold of your personal data. The new malware LeakerLocker has recently been detected which infects Android devices.
Read on to find out exactly what LeakerLocker does on your smartphone and how you can protect yourself.
What is a blackmailer?
But what exactly is a blackmailer? According to Wikipedia, a Trojan is a computer program disguised as a useful program. But in reality, behind the apparently useful program hides another malicious function. This is usually only recognised at a later date or sometimes never recognised. Trojans are malicious programs, or ‘malware’. Criminals are programming a blackmail trojan so that it blocks individual programs, files or the entire computer. The blackmailers demand a ransom for unlocking. This malicious software is also called Ransomware. We’ve often written about blackmail robots, just yesterday, we reported about Marcher.
What does LeakerLocker do?
The LeakerLocker ransomware was detected by cyber security firm McAfee in two apps on Google’s official Play Store – one called “Wallpapers Blur HD” and another called “Booster & Cleaner Pro”.
LeakerLocker attacks all Android devices and is particularly dangerous because more than 80 percent of all smartphone users own an Android device. Gppg;e say that there are over two billion active devices worldwide, reported The Verge.
If LeakerLocker infects your Android device, it will encrypt the phone or tablet. Once installed, the malware claims to have made a backup of your images, messages, browsing history and other sensitive data. It then threatens to send it to all of the contacts, friends and family stored on the phone. You are then told to pay a ransom of around 50 US dollars, usually by credit card. Under no circumstances should you do this because it is by no means certain that your device will be unlocked afterwards. In addition, the criminals will receive your credit card data. And it may well be that the blackmailers demand further money, because they had success the first time. Blackmailers also can threaten to publish private data, photos, e-mails, and your browsing history. Pretty nasty the whole thing.
Where does the blackmailer come from?
LeakerLocker is a blackmail Trojan that you could catch from apps on the Google Play Store. Although the known sources have now been removed from the PlayStore, but there may be others that will appear. It is known that the apps Wallpapers Blur HD and Booster & Cleaner Pro. have been infected. When you install an app and it asks for an unusually high number of permissions. This should make you suspicious. Then LeakerLocker is activated and locks the homescreen. You will be informed that all personal data has been transferred from the smartphone to the criminal’s cloud server. They then say that you have 72 hours to pay the ransom money.
How can you protect yourself against LeakerLocker?
To be protected against malicious malware, you must first of all be alert to the danger. In addition, you should always have a current virus scanner on your device.
Before you download apps, however, look at the reviews carefully. Even if the criminals sometimes slip through the net, PlayStore is still the safest way to load clean Apps onto your own device. Apps from questionable sources should be avoided as well as links, which you may get by e-mail. You should also check the app permissions and not upload if there is any doubt. If LeakerLocker has contaminated your device, the easiest way to remove it is to reset your phone or tablet to factory settings. Although your data will be lost, you can rest assured that the malware has been deleted too.
