According to a new analysis from Check Point Research, ransomware attacks have increased by 102% all around the world in 2021 compared to 2020. In addition, India is one of the most affected countries, with around 213 ransomware attacks per organization weekly which is up by 17% from the start of the year.
The primary reason for the increase in cyber-attacks was a lack of work from home security measures. Not to mention that another major firm, Gyrodata, was recently targeted by ransomware.
Furthermore, numerous ransomware families have recently developed sophisticated tactics for stealing sensitive data. This attack restricts the organization’s confidential, financial or sensitive information by gaining illegal access to an organization’s network. Cyber hackers demand a ransom in exchange for access to files or systems that have been banned.
5 High – Risk Ransomware Attacks
- Ryuk is among the most prolific ransomware attacks and one of the most powerful. It is a sort of crypto-ransomware that uses encryption to prevent access to a file, system, or device till the ransom has been paid.
- In order to attack a system, Ryuk requires other malware. To get unauthorized access to a system, it either deploys Trick Bot or other methods such as Remote Desktop Services.
- Ryuk ransomware mostly targets big companies and government entities that can afford to pay a large ransom.
- REvil is a file-blocking malware that encrypts the victim’s data and sends a query message after attacking the device. The message informs the victim that the demanded ransom must be paid in bitcoin. If the victim does not pay the ransom promptly, the amount demanded is increased.
- REvil ransomware has hit the headlines in the news several times due to data breaches. This attack vector has also been known to target A-list celebrities and release their personal information on the dark web.
- Tycoon is a Java-based ransomware outbreak that was just found. Several companies in the education and software industries, and small businesses, have been targeted by this malware.
- According to reports, this malware employs a variety of strategies to remain undetected.
- Following an attack on the file servers and domain controller, Tycoon infects the system and blocks access to the administrator. It is a typical attack vector that exploits servers for malware and takes use of weak or compromised passwords.
- The Maze is currently the most well-known ransomware threat to businesses all around the world. It was originally known as “ChaCha ransomware” and was discovered on May 29, 2019, by Jerome Segura.
- This vicious ransomware is well-known for its novel style of attack, in which it uses a variety of tactics to make crucial information public. The Maze ransomware encrypts all of your files and demands a ransom to unlock them. If the victim does not pay the required ransom, the information will be released on the internet.
- The threat isn’t inactive, though, since the threat actor actually posts one of the victim’s files on the internet. Even if the victim files a lawsuit against the Maze, the damage has already been done.
- The first victims of the DoppelPaymer Ransomware and its variants were attacked in June 2019. The first version, which appeared for the purpose of testing, had no harmful intent.
- There have been eight different variations detected so far, and it has been established that there are three confirmed victims.
- After encrypting files, the DoppelPaymer ransomware writes a note for its victims. The objectives of this note are comparable to those of BTPaymer’s letter from 2018. The note contains not only the ransom money but also a keyword with a URL and DATA that can be accessed over TOR.
The following are the most commonly advised ransomware prevention measures:
- To develop a cyber-resilient working culture, begin educating staff with security awareness training.
- To decrease the dangers of password sharing at work and the habit of password reuse, mandate a strong password policy.
- To avoid a virus attack, update vulnerable plug-ins regularly.
- Maintain an offsite backup of sensitive data and restrict access to confidential files and the organization’s assets.
- Downloading cracked software from unsafe websites is not recommended.
- Be cautious about clicking on links or attachments in unsolicited emails.
If preventative steps are not taken, security ignorance can cost a company more than its income. In the current situation, attackers have increased their ability to launch new sophisticated ransomware operations. As a result, it is preferable to begin implementing cybersecurity policies as soon as possible, rather than waiting until it is too late.
