RSA-NI ransomware threatens to leak stolen data from targeted companies

RSA-NI ransomware image

RSA-NI virus infects targeted networks to make copies of important documents for the attackers. Later, the victims are asked to pay a ransom in Bitcoins to protect their data from leakage. The ransomware delivers a ransom note as Attention!!! Your data breaches!!!.txt file and its victims are addressed to contact the criminals via 0x720x730x610x30@tutanota.com and 0x720x730x610x31@tutanota.com emails. 

To prevent the companies from accessing their files, RSA-NI virus employs powerful RSA ciphers to encode the information[1]. It is currently unknown what extension it appends following the encryption. However, due to the sophisticated algorithms used, IT experts should struggle to generate the decryption key.

Note that RSA-NI ransomware is surprisingly similar to AES-NI ransomware virus which demands for 500-1600 US dollars. Likewise, cybersecurity professionals link them to the same developers or hacker group. 

According to the malware researchers, RSA-NI ransom note provides the following information:

===============================# rsa-ni ransomware #===============================
IMPORTANT: XXX and XXX

We hacked your server and copied your important data.
Please write us to the e-mail in 24 hours 0x720x730x610x30@tutanota.com  0x720x730x610x31@tutanota.com
After payment, Your data will be destroyed, Otherwise your data will be leaked to the public.
===============================# rsa-ni ransomware #===============================

Ransomware developers give 24 hours to make the transaction and prevent the crooks from leaking it to the public. Even though the CEOs of the companies might be desperate, we suggest you remove RSA-NI and do not encourage them to perform more cyber attacks on other businesses. 

Experts from UdenVirus.dk[2] recommend performing RSA-NI removal with Reimage since it is a professional tool developed to deal with such high-risk computer threats as ransomware. If you have another reliable security software, feel free to use it as well. 

Companies receive spam emails hiding ransomware files inside

Since most of the ransomware attacks targeting businesses happen via infected emails, it is vital to raise awareness[3]. Criminals create well-designed fake letters holding the attachment with ransomware executable and send them worldwide. Usually, they try to convince people into opening them by pretending to be reputable couriers like UPS or DHL.

According to our research, the emails look incredibly genuine and are named as Invoices to trick gullible people. Once clicked, the attachment enables malicious scripts and downloads the payload of the ransomware. Therefore, companies should educate their employees about the possible threats which hide inside innocent-looking emails.

Additionally, ransomware might be designed to impersonate commonly used software updates and put on peer-to-peer networks. Thus, companies are advised to avoid downloading any upgrades to their programs from unauthorized websites which might look legitimate.
