How CyberGhost protect against Ransomware

what is it?

Ransomware is malicious software that blocks access to computer systems or files unless a fee is paid. It is a form of cyber extortion in which the attacker encrypts the victim’s files and demands payment for the decryption, usually in cryptocurrency. Ransomware attacks can also target individuals, businesses, or government entities, causing significant financial data damage.

How CyberGhost Doing it

Our experts in Aegis Cybersecurity Systems install CyberGhost to provide comprehensive solutions to make it impossible for any ransomware.

Although we believe that most Cybersecurity solutions in the race against cybercrime, we start by confirming that crime could happen though, and our solution uses a different approach to make

; 1) data become invisible to unauthorized users, 2) advanced encryption dynamic that makes it difficult for bad actors to decrypt in less than 3 seconds (without being detected) and

3) we track authorized users' performance for unusual behavior

Other Steps

Regularly Backup Data: Implement a robust backup strategy to ensure that essential data is regularly backed up and stored securely. This allows you to restore files without ransom if they are encrypted by ransomware.
Keep Software Updated: Regularly update operating systems, software applications, and security patches to address known vulnerabilities. Many ransomware attacks exploit outdated software with known security flaws.
Implement Security Software: Install reputable antivirus and antimalware software on all devices to detect and block ransomware threats. Use endpoint detection and response (EDR) solutions for advanced threat detection and response capabilities.
User Awareness Training: Educate employees and users about cybersecurity best practices, including how to recognize phishing emails, avoid suspicious links and attachments, and report potential security incidents promptly.
Use Email Filtering: Implement email filtering solutions to detect and block phishing emails and malicious attachments that may distribute ransomware.
Network Segmentation: Segment networks to limit the spread of ransomware in case of a successful intrusion. Restrict access to sensitive systems and data to authorized users only.
Incident Response Plan: Develop and regularly update an incident response plan that outlines procedures for responding to a ransomware attack. This should include steps for isolating infected systems, contacting law enforcement, and restoring data from backups.
Implement Zero Trust Architecture: Adopt a zero-trust security model, where access to resources is granted based on identity verification and least privilege principles, to reduce the risk of lateral movement by ransomware within your network.
Engage with Law Enforcement: Establish relationships with law enforcement agencies and cybersecurity organizations to share threat intelligence and collaborate on investigations into ransomware attacks.

Examples and Recent Attacks

Ransomware gangs posted 24 government-related victims to their extortion sites in March — up from the 19 victims in the previous month and 13 victims in January.
Recent security incidents have hit close to home, with the cities of Birmingham, Alabama, and East Baton Rouge, Louisiana, reporting disruptions in public services. The severity of the situation was further highlighted when Jackson County in Missouri was forced to declare a state of emergency after discovering a ransomware attack.
The Florida Department of Juvenile Justice in Tallahassee also admitted to local news outlets that it was dealing with a cyberattack that forced some systems offline. New York City took a city payroll website offline after a phishing incident. At the same time, the Tarrant County Appraisal District—which determines property values for the Fort Worth area tax purposes—said a ransomware attack hit it.
The threat of ransomware is not static; it's evolving. In March, attacks on healthcare providers saw a slight increase, according to data collected by Recorded Future from extortion sites, government agencies, news reports, hacking forums, and other sources. This trend underscores the need for heightened security measures.
One hack targeting Change Healthcare has disrupted pharmacies and hospitals for weeks. The attack was attributed to the BlackCat/Alphv group, suspected of attempting an elaborate exit scam against its affiliates. Law enforcement had tried to disrupt the cybercrime gang in a December takedown.
The devastating impact of ransomware was demonstrated in May 2017 when the WannaCry attack spread globally. It infected hundreds of thousands of computers in over 150 countries, exploiting a vulnerability in Microsoft Windows operating systems. Mainly targeting computers running older, un-updated versions of Windows and WannaCry encrypted files and demanding ransom payments in Bitcoin to unlock them. The attack caused widespread disruption, affecting businesses, healthcare systems, and government organizations.
NotPetya: In June 2017, the NotPetya ransomware attack infected computers worldwide, primarily targeting businesses in Ukraine. NotPetya disguised itself as ransomware but was later determined to be a destructive cyberattack aimed at causing widespread disruption rather than financial gain. It spreads rapidly through networks, encrypting files and rendering infected computers inoperable. NotPetya affected numerous multinational companies, including shipping giant Maersk, pharmaceutical company Merck, and logistics company FedEx, resulting in significant financial losses.
Ryuk: Ryuk is a sophisticated ransomware strain that has been active since 2018. It has been responsible for numerous high-profile attacks targeting large organizations, particularly in the healthcare and finance sectors. Ryuk is typically distributed through targeted phishing emails and employs advanced encryption techniques to encrypt files on infected systems. The ransom demands associated with Ryuk attacks can be substantial, often reaching millions of dollars. This ransomware has caused significant disruption and financial losses for its victims.
