No More Ransom!

NAJA group - The head of international and legal affairs department of cyber police of I.R of Iran asked people not to ransom to Ransomwares referring to serious threat of cyber extortionists.
Ransomwares are one of the dangerous and newfound malwares that their activities are increasing in recent years and it has become difficult to combat them, Colonel Hosein Ramezani announced in an interview with the reporter of Police News Station.
These malwares restrict users’ own access to main files and their contents by leaking into the victims’ computer and encrypting important files, and then show messages asking some money to decrypt the files and also define a time period to pay as ransom, he continued.
Ransomwares often leak into the victim’s computer by executing infected files attached to the emails or visiting infected websites, and sometimes this is done by the user itself by social engineering method. Reveton, Crypto locker, Cryptowall, Dharma, Cerber and son on, are some known ransomwares that can be referred, he continued.
Ransomwares usually encrypt some important and special extensions file types such as JPEG, TXT, JPG, PPT, DOCX, DOC, PDF, … which have more importance for users, so that they force the victims to pay the ransom, he added.
Preventing to being traced, ransomwares receive the demanded money in Bitcoin or other virtual currencies, he claimed.
According to the official international centers of combatting cybercrime, ransomwares have exposed entities and individual users to moral and material damages in 2016 and the main purpose of the new generation of ransomwares are government organizations, banks and financial institutions, educational centers, health centers and companies, because cyber criminals will achieve more this way, he said.
Indicating that ransomwares have complicated mechanism and the best way to combat them is to prevent computer systems from infection and to block them, he announced some tips about combatting ransomwares:
•    Backup all sensitive data
•    Use anti-virus and anti-malware and update them
•    Activate firewall and configure it correctly
•    Do not open suspicious and unknown emails and attachments
