a battery app made its way into the Play store . Check Point says one of its customers contracted the malware app , dubbed `` Charger , '' after installing what they thought was a battery monitoring tool called EnergyRescue . Researchers with Check Point Mobile Threat Prevention say the malware activates when EnergyRescue runs , and requires admin access to the device . Once that permission is granted , the malware checks for location ( it does not attack phones in the Ukraine , Belarus , or Russia ) , then swipesAttack.Databreachall user contacts and SMS messages and locks down the device . From there , the user is told that they must pay to deactivateAttack.Ransomthe ransomware or they will have their full details spaffed out for various nefarious activities , including bank fraud and spam . `` You need to payAttack.Ransomfor us , otherwise we will sell portion of your personal information on black market every 30 minutes , '' the ransomware tells users . Not ones to be unprofessional , the Charger operators attempt to reassure their victims by offering a `` 100 % guarantee '' that once the 0.2 Bitcoin ransomAttack.Ransom( currently around $ 183 ) is paidAttack.Ransom, all the collected information will be deleted and the device unlocked. `` The ransom demandAttack.Ransomfor 0.2 Bitcoins is a much higher ransom demandAttack.Ransomthan has been seen in mobile ransomware so far , '' note Check Point mobile security analysts Oren Koriat and Andrey Polkovnichenko . `` By comparison , the DataLust ransomware demandedAttack.Ransommerely $ 15 . '' Check Point says that thus far it has not spotted any payments being registered to the Bitcoin address used for the ransom collectionAttack.Ransom, so it is unclear how much , if anything , has been made from this operation .
