Later variants used victims' webcams, requested bitcoin payments, distributed password-stealing malware, and infected Mac and mobile OSes.

Once infected, a pop-up alert purported to be from law enforcement claimed the victim committed a crime - such as downloading pirated software - and threatened imprisonment if the "fine" was not paid via a money payment service. Reveton was a form of financial ransomware delivered via drive-by-download attacks. The calls, however, were rerouted, and the victims incurred additional fees.

After inputting the code into their devices, victims were prompted to call a supposed toll-free number. Victims were instructed to purchase a $10 text message code. The nonencrypting ransomware infected users via a malicious website. WinLock was the first locker ransomware to hit the headlines.

While the RSA encryption key was difficult to crack, Archievus was quickly abandoned once it was discovered the attackers used the same password to lock all files. Once folders were encrypted, victims were directed to an online store only after victims made a purchase would they receive a password to unlock their files. The malware targeted computers' "My Documents" folders. It targeted Windows systems and spread via malicious URLs and spam emails. May 2006: ArchievusĪrchievus was the first ransomware to use a 1,024-bit Rivest-Shamir-Adleman (RSA) encryption key. Unlike many of today's ransomware attacks, GPCode's authors focused on volume rather than individual payouts, sending an exorbitant number of malicious emails and demanding $20 to $70 ransoms. The malware, spread via email, encrypted victims' files and renamed them Vnimanie, meaning attention in Russian. Once members infect computers and collect ransom payments, a portion of the ransom is paid to the RaaS creator under previously agreed-upon terms.Īfter a 15-year lull, GPCode marked the beginning of the internet era for ransomware. The fees depend on the ransomware's complexity and features, and generally, there's an entry fee to become a member. RaaS creators host their ransomware on dark net sites and allow criminals to purchase it as a subscription - much like a SaaS model. RaaS involves perpetrators renting access to a ransomware strain from the ransomware author, who offers it as a pay-for-use service.However, paying the ransom does not guarantee protection of the data either, as the attackers have access to the stolen data. This means that, even if a victim can restore their data from backup, the attacker still has power over them. With double extortion ransomware, attackers threaten to publish stolen data if their demands are not met. Double extortion ransomware encrypts files and exports data to blackmail victims into paying a ransom.Crypto ransomware spreads through various means, including malicious emails, websites and downloads. Some newer variants also infect shared, networked and cloud drives. It encrypts all or some files on a computer and demands a ransom from the victim in exchange for a decryption key. Crypto ransomware is more common and widespread than locker ransomware.To unlock your computer, you must pay a $100 fine," or "Your computer has been infected with a virus. A pop-up on the victim's screen may appear saying, "Your computer was used to visit websites with illegal content. Once inside, threat actors block users from accessing the system until a ransom is paid. This variant uses social engineering techniques and compromised credentials to infiltrate systems. Locker ransomware blocks access to computer systems entirely.More recently, double extortion and ransomware as a service ( RaaS) have become popular among threat actors. Historically, the two main types of ransomware are crypto and locker. To understand the concept, let's look at the four types of ransomware, along with examples of specific ransomware strains and their effect on the security landscape.
