The ransom demands imposed by the new “RobbinHood” ransomware family increase $10,000 each day beginning on the fourth day following encryption.
The creators of RobbinHood appear to be aiming their attacks at entire networks. When they’ve gained access to a target, they use their ransomware to encrypt as many computers as possible. They then drop ransom notes under four different names on the infected machines.
Each copy of the ransom message provides victims with two options of payment: pay three Bitcoins (currently worth $15,476.47) per each affected system or seven Bitcoins (currently worth $36,111.76) to recover all affected systems. Each note then informs those who have suffered an infection that the ransom amounts will increase by $10,000 each day if they haven’t paid by the fourth day after encryption.
