Safeguarding Against the Five Stages Of a Ransomware Attack

 It also discovered that it does not pay demand for ransom. 80percent of ransomware victims were again hit by ransomware. 68% of them said it was a ransomware-related attack that happened in less than a month. The threat actors demanded a higher ransom.

The Cybersecurity and Infrastructure Security Agency (CISA) released an unofficial report in February which stated "The demand for ransomware is becoming increasingly professional in 2021." It also stated that the evolution of ransomware strains last year "demonstrates...threat actors' growing technological sophistication."

Sending out spam messages to people filled with malware which results in demand for ransoms of thousands of dollars are gone. The ransomware operations that are targeted are called RansomOps. Our research report RansomOps The Insider's Guide to the complex Ransomware Operations along with the Ransomware Economy analyzes the "low" as well as "slow" attacks, which attempt to remain under the radar in order to penetrate as much of the target's network before an order for ransom can be issued.

It is essential that you are aware of characteristics and the evolution of ransomware attack so that companies can avoid being targeted.

Five stages of RANSOMWARE ATTACK

RansomOps attacks can happen in various phases. Gartner defines as compromise and ingress burrowing/tunneling as well as Command and Control. The five phases are what we'll be examining and how we can stop these five stages.

• First Ingress The attack starts with the ingress (i.e. the first attack point). It can be the result of a compromised site or an unsecured API endpoint or an unauthorized actor who has stolen credentials. The vulnerabilities are easily identified and unsafe practice in IT are revealed through penetration testing. Penetration testing should also comprise tests to test for penetration that are based on OWASP standards.
• Compromise This happens where you download the Downloader downloads onto an individual's computer and initiates the infection phase. Endpoint detection as well as response (EDR) tools are capable of detecting malicious activity and prevent the spread of. EDR is defined as "an array of modern integrated security tools for endpoints which detect, stop and study the invasive cyber security threats that are high in the chain of cyber-attacks."
• Tunneling or Burrowing After entering, hackers "burrow into", "tunnel-up" from the prem resources, and proceed laterally across the network obtain access to network prior to releasing the ransomware payment. This is a problem that can be prevented making use of endpoint controls like firewalls and segmentation of networks, along with robust patch management and vulnerability monitoring.

• Command and Control The installation process makes use of commands and control channels (C2) for downloading additional malware programs, and eventually , the ransomware payload. A Extended Response and Detection (XDR) solution can stop and detect this kind of process. The solution uses AI to spot potentially malicious chains and behaviors that could result in the possibility of a RansomOps attack. Certain combinations of behaviors can be extremely rare or provide attackers a distinct advantage. Your team should be able to differentiate between malicious and benign the use of legitimate tools, for instance, "living in the land binaries" executions that make use of legitimate tools to carry out malicious activities.

• encryption The attacker then attack with ransomware, and encrypt the all assets that are on the network, and keep them in a hostage situation until the victim is able to pay. RansomOps smugglers additionally employ double-extortion methods to ensure that payment. Certain ransomware gangs employ double extortion to steal sensitive data from their targets prior to the launch of an encryption application. To stop attackers from publishing data of victims online the threat actor demands that the victims pay an additional charges. Cybereason CEO LiorDiv discussed the various levels of exortion businesses face when their data is stolen.

RANSOMWARE PREVENTION

WannaCry affected more than 7000 computers in the space of an hour , and more than 100 millions IP addresses in the following two days. Even though we know that it was removed however, it was an amateur in nature and would not have been prevented. There are two options available in managing ransomware. You can either respond or you can stop it from occurring.

A lot of companies make use of backups to guard themselves against ransomware attacks. However, as we've explained, this will only cover only a small portion of the damage. While it's a good choice to backup information as well as systems, this won't solve the issue with double-extortion.

An effective ransomware prevention program that is efficient includes measures like:

• Security Hygiene Best Practices: These include timely patch management, making sure that operating system software is regularly updated, establishing an awareness program for security that is able to deploy the top-of-the-line class security tools to the network.
• Multi-Layer Protection Capabilities implemented: Enterprise endpoints should be equipped with NGAV as a requirement to stop ransomware attacks that rely on both known and custom TTPs.
• Deploying Endpoints and Extended Detection and Response (EDR or XDR: Point solutions that detect criminal activity like RansomOps attack across the entire environment offer the necessary visibility to stop ransomware-related attacks prior data leakage or to deliver the ransomware's payload.
• Key Players to Ensure security: Responders Should be accessible all hours of the day. All Hours of the Day. Critical mitigation efforts can be delayed due to holiday and weekend breaks. It is crucial to clearly define the procedures for the duties of on-call personnel in case of security emergencies that happen during non-business hours.
• conducting periodic top exercises These drills that cross-functionally are designed to be involving key decision makers in Legal, Human Resources, IT Support, as well as other departments, in order to make sure that the incident response is smooth and efficient.
• Implementing clear and consistent isolation practices: This will prevent any further intrusions into the network or the spread of the ransomware onto other systems. Teams must be able to shut down a host or account that is compromised, and then lock it down and block malicious domains and so on. These processes should be tested with routine or non-scheduled exercises at least every quarter to make sure that all processes and personnel perform as they should.
• Evaluation of the Managed Security Services Provider Option: If your security company is suffering from difficulties with staffing or in terms of skills it is possible to establish agreed-upon responses with your MSPs to ensure that they are able to immediately respond to the agreement on a plan.
• Protection of Critical Accounts during Holiday and Weekend Periods. An attacker will typically follow the following path to spread ransomware over networks: increase privileges to the administrator level of the domain and then release it. It is essential to create highly secured emergency-only accounts that are part of their directory of active. They can only be utilized when operating accounts become temporarily shut down or blocked by ransomware attack. It is also recommended to use similar measures to protect VPN access, which means limiting access to it on weekends and on holidays based on the needs of your business. Our study for 2021 organizations at risk Ransomware hackers don't have holidays offers more details about holiday and weekend ransomware risks.
