What is Iiof Ransomware?

Iiof ransomware is a type of malware that encrypts all the files on a computer until the user pays a ransom. Files encrypted by Iiof will have a .iiof extension appended to the end of the file name. Iiof is delivered through a Win32 EXE file and has been spotted inside the following files and processes: ['C62F.exe', '6A42.exe'] The Iiof ransomware can read ini files, download files from web servers, and query the cryptographic machine GUID. It can also spawn processes and perform DNS lookups.

What is Ransomware?

Ransomware is a type of malware that encrypts a user’s files or device, blocking access until a ransom is paid. The malware is spread through phishing emails, fake downloads, and other social engineering tactics. Once installed, the ransomware can spread to other devices on the same network, and network-mapped drives. After installing itself, ransomware typically demands a ransom from the victim, in an online currency such as Bitcoin.

Ransomware can be delivered via an email attachment, a link in an email, or a download from a website. Once clicked, the ransomware is downloaded, installed, and activated.

Iiof ransomware Capabilities

Iiof ransomware may use process injection techniques to evade process-based defences and possibly elevate privileges. By injecting code into other processes, Iiof ransomware may be able to access the memory and resources of those processes and gain elevated privileges. Additionally, process injection may help to evade detection from security products. Iiof ransomware employs a variety of techniques to infect its victims. These include the use of non-application layer protocols, such as ICMP, to communicate between hosts and redirected protocols, such as Serial over LAN.

Additionally, Iiof ransomware may use a variety of methods to spread within a network, including exploiting vulnerabilities or using social engineering tactics. Iiof ransomware uses masquerading attack techniques to make its artifacts appear legitimate or benign to users and security tools. It may also rename abusable system utilities to evade security monitoring. Iiof ransomware may use obfuscated files or information to avoid detection and analysis. This may include encryption, encoding, or compression of files and the use of separate files that only reveal malicious functionality when reassembled. Additionally, Iiof ransomware may obfuscate commands executed from payloads or directly via a Command and Scripting Interpreter. 

 

Mitigations Against Iiof Ransomware :

Endpoint security solutions that can be configured to block process injection based on common sequences of behavior can help mitigate ransomware attacks. Network intrusion detection and prevention systems that use network signatures to identify traffic for specific adversary malware can also help mitigate ransomware attacks. Additionally, requiring signed binaries can help reduce ransomware attacks.

How to Protect Against Ransomware?

The best way to protect yourself from ransomware is to ensure you do not download any malicious software. There are two ways to do this. The first is to make sure that your computer's security software is up-to-date. This protects against any known forms of ransomware. The second is to only download software from trusted sources. If you are downloading software from the internet, make sure that you download it from a trusted website.

There are a few steps that you can take to protect yourself against ransomware. The first is to make sure that you have a backup of your data. This will make it easy to restore your information if the worst should happen. You should also ensure that you have a secure password on your computer and never click on anything from an email that you're not sure about. Additionally, you can use software that can detect and block ransomware, such as antivirus software, endpoint protection, or a web security gateway. 

Other tips to protect yourself against ransomware include: 

  • Install antimalware software.
  • Keep all software up-to-date.
  • Do frequent backups of your files.
  • Install antivirus software.
  • Implement two-factor authentication.
  • Use a firewall and spam filter.
