Among The Most Common Cyber Attacks Is Ransomware. How To Recognize And Defend Them
One of the most widespread and frequent cyber threats has been ransomware attacks in recent years. Many companies and institutions are affected by cybercriminals that manage to encrypt data using this type of virus, making it impossible to access it except with an access key.
The key that can unlock the encrypted data is only provided in exchange for a ransom, generally required in cryptocurrencies such as Bitcoin, with the threat of data deletion if the ransom is not paid by a set date.
It is estimated that at least 62% of companies will experience such an attack in 2020.To learn more about this threat and what to do to defend yourself. It is helpful to follow the advice of the data recovery specialists at Recovery Data.
The Four Most Common Types Of Ransomware Attacks You Should Know Here
According to the Clusit Report (Italian Cyber Security Association) of 2021, Ransomware accounts for two-thirds of cyberattacks (more precisely, 67%); this threat, highly profitable for cybercriminals, has evolved over the years to deal with the defensive measures adopted by companies.
Four popular types of Ransomware use different techniques:
Lockers: Block access to all computer systems, use social engineering techniques to infiltrate computers. Usually, a pop-up appears on the screen with the ransom note and the instructions to follow for the payment.
Crypto: Can spread via emails, sites, and download infected files, encrypt all files on a computer, and block access even to entire servers. They are the most common Ransomware, and ransom requests always involve the release of a decryption key to get back all the stolen data.
Double Extortion: In this case, the threat consists not only in data encryption but also in the possibility that sensitive data is made public or sold on the Dark Web for other attacks. For this reason, even restoring from backups does not guarantee that the data will not be disseminated illegally.
RaaS: the acronym stands for Ransomware as a Service. It is a strategy that involves malware developers, who offer their services as a subscription to criminal organizations that would not have the technical skills to carry out such attacks.
In this way, the number of attacks and their accuracy increase.
