Sleep Pattern WhatsApp Users Easy To Follow

It's easy to follow WhatsApp usage and sleep patterns of WhatsApp users. For example, information that can be sold to health insurers and credit agencies, says software engineer Robert Heaton . Using only the WhatsApp user's phone number, it is possible to read his status, as if he is online and when he was last seen.

It is not necessary to be friends with the WhatsApp user. Only a phone number is sufficient. Heaton wrote a simple script that requests information every 10 seconds at WhatsApp. Then he processed the data in a graph, making it clear that the sleep pattern of the WhatsApp user he wanted to follow became clear. Users can set to see their "last seen" status show. By default, however, this status is visible to everyone. Additionally, users can not hide their "online" status.

According to Heaton, it is so easy to make graphs of both theirs and strangers using their WhatsApp use and sleep patterns. Information that can be sold to health insurers and credit agencies that are interested in "deviant behavior", for example, let the engineer know. Other scenarios are outlined at Hacker News , which allows the status information to communicate which friends communicate in a contact list via the status information. For example, it may be outdated whether people are cheating or having an affair.

Ransomware Irritates Users Via Audio Message

Besides which also ransomware encrypts files or computers locking is ransomware that attacks only the browser, and a new variant users try a different way to force them to pay. The browser ransomware pretends to be "Microsoft Official Support".

A pop-up ransomware users to believe that there are problems with the computer and a phone number to be called. In addition, an audio message will be repeated continuously which states that there are viruses and adware on the computer are available and the specified number to be called to remove them. If users try to close the pop-up will open a new pop-up.

Unlike ransomware that encrypts or locks the computer files, browser-ransomware is easy to solve. Users can close the browser using the Task Manager, which is also browser-ransomware disappears. Security firm RSA says that despite the simplicity of the solution, this ransomware focuses on users who have no knowledge of this type of threat or know how they can remedy via Task Manager, and finally call the telephone number provided. This number is then the victim of scam artists who try to light up.

Google Removes Malware From Google Play Store

Google has removed a malicious app from Google Play that occurred as a backup service, but in reality, text messages, call information, and device information was trying to steal. The app was called "Save Me" and claimed that users through the service could save their contact information. In order for the service to notify users had to specify information such as name, email address, phone number, country and there had to be a personal photo will be uploaded.

Once activated the malware did however connect to a server and send contact information, text messages, call information, such as numbers, date and time and device information back. Also removed the malware own icon. The attackers behind the malware used a spam campaign by Bit.ly shortened links to spread the app. Analysis of Bit.ly -Left show that was nearly 6,000 times clicked, mainly in Africa. It is unknown how many people actually have the app installed.

Security firm Lookout discovered the malware and then warned Google that the malicious app removed. To prevent infection by this type of malware, users advised to only download the official market place and then only apps from known developers.Users therefore have first read the reviews and research the developer so that they are sure that it is a reliable product."Especially if it is a tool that promises to protect sensitive information," says Jeremy Linden Lookout.
