Mid 2011 - The first large-scale ransomware outbreak marks ransomware's move into the big time due to the use of anonymous payment services, which made it much easier for ransomware authors to collect money from their victims. Two years after the initial GPCode virus was created, a variant called GPcode.AK was unleashed on the public using a 1,024-bit RSA key. WinLock displayed pornographic images until the users sent a $10, premium-rate SMS to receive the unlocking code. 2007Īt the same time that GPCode and its many variants were infecting victims, other types of ransomware circulated that did not involve encryption, but simply locked out users. June 2006 - the GPCode, an encryption Trojan that spread via an email attachment purporting to be a job application, used a 660-bit RSA public key. The Archiveus Trojan encrypted everything in the MyDocuments directory and required victims to purchase items from an online pharmacy to receive a 30-digit password.

It was the first ransomware virus to use RSA encryption. Seventeen years after the first ransomware malware was distributed, another strain was released, but the Archiveus Trojan was much more invasive and difficult to remove than its predecessor. But the AIDS Trojan set the scene for what was to come. The Trojan used simple symmetric cryptography, and tools were soon available to decrypt the filenames. The AIDS Trojan was “generation one” ransomware and relatively easy to overcome. Popp sent 20,000 infected diskettes labeled “AIDS Information - Introductory Diskettes” to attendees of the World Health Organization’s international AIDS conference.

It was called the AIDS Trojan, also known as the PC Cyborg. The first ransomware virus was created in 1989 by Harvard-trained evolutionary biologist Joseph L. ( This 101-page primer can help you get going if you need to pay a ransom.) Recently, sophisticated cyber-gangs have penetrated whole networks, infecting all machines at the same time and extorting tens of thousands of dollars.īut that's what ransomware has become.

Payments are typically required to be in an untraceable crypto-currency such as bitcoin. According to Microsoft, 42 percent of attempted recoveries from tape backups in the past year have failed.Ī ransom is usually about $500 if paid within a certain time frame, and when that deadline expires, the ransom doubles. Storage Magazine reports that over 34 percent of companies do not test their backups, and of those that tested, 77 percent found that tape backups failed to restore. The only way to get encrypted files back is to restore a recent backup or pay the ransom. As an illustration, CryptoWall has generated over $320 million in revenues. Ransomware is a very successful criminal business model. Strains of ransomware come and go as new cyber-mafias muscle into the 'business.' Some examples are CryptoLocker, CryptoWall, Locky, and TeslaCrypt.

Once a user finds that access to the files is blocked and alerts a system admin, the sysadmin usually finds two files in the directory that indicate the files have been taken hostage, along with instructions on how to pay the ransom to decrypt the files. Once the malware is on the machine, it starts to encrypt all data files it can find on the machine itself and on any network shares the PC has access to. The user gets tricked into clicking on a link or opening an attachment. What we call ransomware today is malware that usually gets installed on a user's workstation (PC or Mac) via a social engineering attack. The state of ransomware: A rising criminal enterprise Here is a brief history of the evolution. Understanding how ransomware has evolved is the first step to planning your defense. “ You could spend a fortune purchasing technology and services, and your network infrastructure could still remain vulnerable to old-fashioned manipulation. New strains of ransomware regularly get spotted in the wild, as cybercriminals furiously innovate in both the technical and social engineering areas. This is only the early days of ransomware, but it’s a very successful criminal business model with many copycats. It is highly effective because the encryption used is practically impossible to break.

There are many variants some ransomware is designed to attack Windows PCs, while other strains infect Macs and even mobile devices. Ransomware is vicious malware that locks users out of their devices or blocks access to files until a sum of money, or ransom, is paid. Ransomware attacks cause downtime, data loss, and possible intellectual property theft and in certain industries are considered a data breach.
