As a refresher, ransomware is a malware that is activated by a user clicking on a website, opening an attachment or clicking on link from email or text message that has been infected. Typically, the hackers using the phishing technique try and trick users into clicking on links or opening attachments that launches the ransomware. Ransomware focuses on the number one vulnerability, people and infects all devices connected to the network. Typically encrypting the data and demanding money. Now that company’s have such large amounts of data it is too difficult to copy the data outside the network. So, hackers are encrypting the master boot record so the server will not boot up. Another tactic is to encrypt the data on the network, but extract sensitive data like customer data, social security numbers, date of birth, addresses, emails, trade secrets, etc., and demand money or the information will be released or sold on the dark web. The good news is this is preventable by educating users because the ransomware cannot be launched if the user does not click on the link.
NetWalker Ransomware Gang
According to ZDNet, NetWalker ransomware gang has made a profit of $25 million since March 2020. The gang of hackers has started ransomware-as-a-service (RaaS). RaaS is when hackers ban together and sign up through a vetting process, after which they are granted access to a web portal where they can build customer versions of the ransomware and profit share. The NetWalker process usually involves three phases: (1) NetWalker breaches company network to steal company’s data and encrypt files, (2) if the company does not pay the ransom they are posted to the NetWalker leak site, and (3) if the ransom is not paid NetWalker leaks company data after a certain period of time. Some company’s pay just to avoid the press nightmare.
