Baltic news, News from Latvia, BNN.LV, BNN-NEWS.COM, BNN-NEWS.RU«Predictions made by experts for 2017 are starting to come true – to new types of malware have increased the ranks of the army of ransom viruses. These two are Spora and Marlboro,» – eScan antivirus software representatives say.

«One of the hackers’ goals is to scare users. Marlboro, for example even includes in its ransom notes links to Wikipedia articles about encryption keys to convince victims of how serious encryption is and to intimidate them,» – comments IT Baltimax sales managed Devids Pelenis.

Marlboro ransom virus is considered amateur-level malware. After encrypting files and giving them ‘.oops’ extension, the virus shows a notification that the user’s files are encrypted using RSA-248 and AES-128 encryption algorithms. Analysis of Marlboro revealed that it uses a much simpler XOR algorithm, eScan experts say.

To recover encrypted files, Marlboro demands ransom from victims in the form of bitcoins. Hackers also provide detailed information how to buy bitcoins and which portals are best for it.

Spora ransom virus is more complicated – it is professionally made and uses AES and RSA encryption algorithms. However, eScan experts are more interested in the creativeness of the creators of the virus, offering victims a selection of services and ransom pay: decryption of files, OS recovery, immunity against future attacks and deletion of malware.

«Speaking of the last two services – the option to delete malware and gain immunity – it looks as though hackers want to please the users that create reserve copies of files. I any case, victims should not pay ransom money,» – Pelenis says.

Both viruses are distributed using e-mails. Antivirus representatives recommend looking for free decryption tools instead of paying ransom money. It is also highly recommended to reinstall the OS and install an antivirus.
