What is Ransomware?
Ransomware is a type of malware with the ability to encrypt or lock-down, one's personal data so victims cannot access it. To have that data unlocked, you must pay a ransom to gain access. When you pay the ransom, there is no guarantee that your personal files will be unlocked and even work after payment.
How Does Ransomware Spread?
Ransomware spreads through various means. Some ransomware is spread by the owner of the ransomware that they install, while malicious programs spread other forms of ransomware. The malware may be hidden in an email attachment or embedded in a website web page to invade your personal computer without your knowledge.
How Does Iwan Ransomware Work?
Iwan Ransomware is ransomware that encrypts the user's files and demands a ransom. Ransomware is typically sent to victims via email or accessed through an infected file downloaded from the Internet. When Iwan Ransomware is activated, it searches for documents and other data on local drives and mapped network shares. After finding data, it encrypts them with asymmetric encryption using an RSA key pair generated on the spot, then attempts to send a pattern file to each of up to 50 email addresses supplied by its Command & Control server after connecting to it over an SSL encrypted connection.
At the same time, the malware also sends a pattern file to a specified victim's email address. The first file is a detailed report of the operation on the victim's computer, while a second pattern file is a ransom note, which must be opened on screen for Iwan Ransomware to decrypt them using its RSA private key. Both files are encrypted with AES-256 and use a random RSA private key on each file.
