IronHead ransomware removal instructions
What is IronHead?
Discovered by Michael Gillespie, IronHead is a computer infection that is likely to be a part of the Scarab ransomware family of viruses. Like most ransomware-type viruses, it is designed to prevent users from accessing their data by encryption. To recover their files, IronHead victims are encouraged to pay developers a ransom (purchase a decryption key). Once encrypted, all affected files are renamed by adding the ".ironhead" extension. For example, "1.jpg" becomes "1.jpg.ironhead". IronHead also generates a ransom-demand message within "How to restore encrypted files.txt", and places the file in folders containing encrypted files.
IronHead developers state within the "How to restore encrypted files.txt" ransom-demand message that the victim's files (data) were encrypted due to 'security problems' with the computer. Users of infected computers are urged to contact cyber criminals via the firstname.lastname@example.org (or email@example.com) email address and to send the personal identifier provided. They state that sending the email will indicate that the user is ready to pay a ransom (buy a decryption key). The exact cost (size of ransom) is unknown, however, cyber criminals claim in their ransom note that this depends on how quickly they are contacted. It states that the ransom must be paid in Bitcoins. According to IronHead developers, they will provide victims with a decryption tool as soon as payment is made. As 'proof' that they can be trusted and are capable of decryption, they offer free decryption of up to three files prior to receiving payments. They also warn affected parties not to rename encrypted files or to use any other decryption tools, since this might cause permanent data loss or increase the cost of decryption. Most cyber criminals (ransomware developers) use cryptography algorithms (symmetric or asymmetric) that generate unique decryption keys. They store these keys on remote servers under their control. Therefore, decryption without the involvement of ransomware developers is impossible. Furthermore, no tools are currently capable of cracking IronHead cryptography. Despite this situation, do not contact any ransomware developers. Typically, they ignore victims once they receive payment. We recommend that you use a backup and retrieve files from there.

IronHead is just one of many ransomware-type infections. Example of other similar viruses include UnblockAndRecover, Djvu, and .SYS. They might be developed by different cyber criminals, but most serve the same purpose: to encrypt data and make ransom demands. The most common variables are cost of decryption and cryptography algorithm used for encryption. Unfortunately, most ransomware viruses are 'uncrackable'. Cracking them might only be possible if the virus is still in development or contains bugs/flaws. To prevent data loss in the future and avoid becoming a victim of ransomware, maintain regular data backups and store them on remote servers or unplugged storage devices.
How did ransomware infect my computer?
It is difficult to determine exactly how IronHead developers proliferate this high-risk infection, however, most cyber criminals use similar methods. They often use spam email campaigns, trojans, fake software updaters, and third party download sources. Regarding spam campaigns, cyber criminals send emails that contain malicious attachments and attempt to trick people into opening them. These attachments are usually Microsoft Office documents, PDF files, archive files (such as RAR, ZIP), executables, and so on. Once downloaded and opened, they infect computers with viruses. Trojans are malicious programs designed to proliferate other infections. When a trojan is installed, it causes chain infections. Fake/unofficial software updaters download and install malware rather than updates or fixes, or they exploit bugs/flaws of outdated software. Third party download sources such as P2P (peer-to-peer) networks, free file hosting websites, freeware download websites, or other similar channels, also proliferate viruses. Cyber criminals use them to present malicious files (executables) as legitimate and often trick people into downloading and installing high-risk infections.
How to protect yourself from ransomware infections?
Be careful when downloading, installing/updating software, and opening emails. Avoid opening email attachments (or web links) that are received from unknown/suspicious addresses, or if the email subject and context is irrelevant. Use official and trustworthy sources when downloading software, and not third party downloaders, installers, and so on. Update installed software using implemented functions or tools provided by the official software developers. Having a reputable anti-virus or/and anti-spyware software installed is also important: these tools can detect and remove threats before they proliferate or do any damage. If your computer is already infected with IronHead, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
