In fewer than two years, the GandCrab ransomware has generated over $2 billion in income. The dissemination of RaaS contributed significantly to this total. GandCrab’s authors established a network of affiliate partners and were able to disseminate the ransomware software internationally, with each assault giving them a sizable portion of the revenues.
RaaS will not only continue to be a threat to enterprises under this paradigm, but we can also anticipate it growing in the near future-both in terms of volume and intensity of the assault.
15 effective ways to defend ransomware attacks
Organizations must now take precautionary measures to safeguard their infrastructure and network resources from more sophisticated ransomware assaults.
Here are 15 things you can start doing right now:
Operating systems, gadgets, and software applications should all be updated and patched.
Use IOC lists and inventory tools to prioritize the most vulnerable commodities.
Update the network intrusion prevention system (IPS) signatures, antivirus, and anti-malware software on your devices.
Back up systems and offline backups, as well as any devices required to restore the network.
Conduct recovery drills and assign duties ahead of time so that systems can be restored swiftly in the case of a successful assault.
Update your email and online security to ensure that all email attachments, websites, and files are malware-free.
In a safe environment, they use sandbox technologies to examine and execute new or unknown files.
Ads and social networking sites that are irrelevant to your business should be blocked.
Use zero-trust network access with virus scanning so that users do not inadvertently infect key corporate programs, data, or services.
Devices that do not comply with the security policy should be inspected and blocked.
To prevent illegitimate apps from being downloaded or launched, use whitelisting apps.
Using a CASB solution, you can prevent illegal SaaS applications.
To prevent the spread of viruses, divide your network into security zones.
Use forensic investigation techniques to determine where the virus originated, how long it has been in your environment, if it has been eliminated from each device, and whether it will return.
Plan your security strategy around the weakest link in your system: the employees who utilize the company’s devices and apps. Training is necessary, but it is restricted. Most, if not all, phishing emails and hazardous attachments may be removed with the right technologies, such as secure email gateways.
Summary: Protection requires training
Organizations must dramatically increase their efforts to defend themselves as hackers extend their RaaS market with additional ransomware choices to boost their profit possibilities. Perpetrators concentrate their attacks in order to maximize their impact and income, frequently combining highly focused attacks with increasingly powerful and surprising means. Organizations that plan ahead of time have the best chance of fending off this new wave of criminal activity.
