Using RAM booster for Android Mobiles.

        Android being one of the largest smartphone operating system is used by many people across globe. Millions of applications are there in Android Play Store and many of them are commonly used by many people. One among them is RAM booster or Cache Cleaner applications.

       In this blog post I am going to discuss the findings of one such common application used by almost more than 50 million users across globe. It falls under RAM booster category and cleaner application.

       One thing that has to be made clear is that Android has good RAM management and cache management program. Almost all the devices comes with average of 2 Gigabytes of RAM so there are 2 Gb available for applications.

       Unused RAM memory is Wasted memory according to many researchers. Ok lets see the functioning of any RAM cleaner application.

        Consider you are running a RAM cleaner application, it will kill the application that is dormant and also delete cache files. After that a nice GUI will tell you that almost 300 Mb has been restored. Ok in background after quitting the application or after the cleaning the application that has been killed will be again assigned to RAM and will create all deleted files again which takes more resources than before.

        Some applications will have cache files with some important data before saving in DB file or in backgorund file before that running RAM cleaner may delete the files and the application if required will download data from Internet which costs Mobile Data.

        Another nice thing is while analysing I came across an application that upon opening sharing IMEI number, Mobile model, Phone Build, Brand Name, Carrier Name and many more to famous Advertising company. 

         As a final thing using these types of RAM cleaner or Cache Cleaner will only take more resources and drain your battery and also may steal your details about device. Think before using it next time.

        For security reasons I am not disclosing the application name, here RAM cleaner referes to normal cleaner application.

Hack Windows / Mac Login Password using USB.

           It is not the new story that the USB drives has been used to steal credentials. There has been USB drives that explodes when connected and there are drives that will steal the credentials when plugged in. Recently yet another evil USB has been developed by a researcher.

           A security researcher developed a USB drive that will identify themselve as a network gateway and also as DNS server using the ethernet port. USB drive in USB port will have some restrictions before loading but the ethernet port will be whitelisted in the machine for sure.

           The device dubbed as evil USB upon inserting in the ethernet port will identify itself even the computer is locked out and then the drive will try to sniff the hashed credentials and stores them in the SQLite Database.

           After that the database entries can be cracked to find the password stored. The researcher tested this in many versions of Windows machine and also Mac running EI Captian and also Mavericks. 

           The only limitation for this attack is that the attacker need to have physical access to the computer for almost 13 seconds.
