As the world turns digital, SaaS, or Software-As-A-Service, has become an important feature. However, there is also an increasing cybersecurity industry in the underground world.  RaaS or Ransomware-As-A-Service may encourage people without expertise to carry out a sophisticated ransomware attack. It does not need a skilled hacker or a team of hackers to attack them. The rise of the underground RaaS industry is alarming, as it reveals how easy it is to infect people with ransomware.

This malware compiled in ImageJ is known to be out of the ordinary because it has been added to the Java Runtime Environment update.

Infecting the system, Tycoon refuses entry to the administrator and then launches another attack on file servers and domain controllers.

Ryuk Ransomware

 Ryuk is among the most prominent ransomware. It is a form of crypto-ransomware that blocks entry to a file, system, or computer through encryption before the ransom is paid.

This ransomware uses other malware to exploit the system. Either it uses TrickBot or other methods, such as Remote Desktop Facilities, to obtain unauthorized access to the device. It uses robust military algorithms such as RSA and AES to encrypt files using a single key for each executable. It also primarily targets corporate giants and government departments who will pay massive ransoms in exchange.

Zeus Gameover

Zeus Gameover is a member of the Zeus family of malware and viruses. This type of malware is a Trojan, a malware disguised as legitimate, that accesses your confidential bank account data and collects all your money.

While cryptojacking attacks decreased dramatically in previous years, mainly due to a steep drop in cryptocurrencies’ valuationthis pattern remains dangerous. As cryptocurrency values begin to grow this 2020, cryptojacking ransomware attacks will continue to be profitable for cybercriminals.

Social Engineering

Humans can be the weakest connection of any security protocol. That is why cybercriminals are now turning to human psychology and manipulation to obtain access to personal information.

The hacker would begin by contacting a business or service provider and claim to be a particular individual. They will ask questions about the victim’s account and trick the customer service staff into turning over classified information bits. They would then use the information to obtain access to a person’s account and records, including payment details.

While this is not a form of malware per se, social engineering is disturbing, as it does not require hackers to know about coding or malware creation. Instead, the attacker wants to be persuasive and encourage human error and complacency to reward them with the data they need and release malware once they have access to any system.
