Beware of Ransomware

2.3K

The Ransomware attacks are on rise. Being an IT Support company, we are getting lots of calls for Ransomware attacks from our end customers. The frequency of these attacks is a major concern.

What is Ransomware?

Ransomware is an access-denial type of attack that prevents users from accessing files on their PC or laptop. Since it is intractable to decrypt the files without the decryption key. There are many variants that can affect one or many systems and network- attached drives.  As per an estimate, there are now more than 100 separate families of ransomware. The big profile target included University of Calgary,  transferred 20,000 Canadian dollars-worth of bitcoins, after it was unable to unwind damage caused by a type of attack known as ransomware. The malware caused emails and other files to become encrypted. Similarly, In February, the Hollywood Presbyterian Medical Center paid $17,000 to restore access to its system. The FBI has warned that it had seen ransomware attacks double in the past year, with more than 2,400 complaints.

Why Are Ransomware Attacks Emerging?

Ransomware attacks are emerging and becoming more prevalent due to several key factors:

1. Lucrative for Cybercriminals: Ransomware offers a quick and often highly profitable return for attackers. By encrypting critical data and demanding a ransom for its release, cybercriminals can extract significant sums from organizations desperate to regain access to their systems.
2. Increased Digitalization: As businesses and individuals increasingly rely on digital platforms and data, the potential impact of a ransomware attack has grown. This makes organizations more willing to pay ransoms to avoid disruption, further encouraging attackers.
3. Availability of Ransomware-as-a-Service (RaaS): The rise of RaaS platforms has lowered the barrier to entry for cybercriminals, allowing even those with limited technical skills to launch sophisticated ransomware attacks. This has led to a surge in the number of attacks.
4. Exploitation of Security Gaps: Many organizations have inadequate cybersecurity measures, outdated software, and unpatched vulnerabilities, making them easy targets for ransomware attacks. Attackers exploit these weaknesses to gain access to systems.
5. Remote Work and Cloud Adoption: The shift to remote work and increased cloud adoption, accelerated by the COVID-19 pandemic, has expanded the attack surface for ransomware. Many remote work setups lack robust security, making them vulnerable to attacks.
6. Sophistication of Attack Techniques: Ransomware attacks have become more sophisticated, often involving double extortion tactics where attackers threaten to leak sensitive data if the ransom is not paid. This increases pressure on victims to comply with ransom demands.

These factors, combined with the evolving tactics of cybercriminals, have made ransomware one of the most prominent and growing threats in the cybersecurity landscape. Contact to Synergy IT Solutions group to solve.

How Ransomware Works ?

Ransomware works by infiltrating a computer system, encrypting the victim’s data, and then demanding a ransom payment in exchange for the decryption key. Here’s a step-by-step breakdown of how ransomware typically operates:

1. Infection:
   • Phishing Emails: The most common method of infection is through phishing emails containing malicious attachments or links. When a user opens the attachment or clicks the link, the ransomware is downloaded onto their system.
   • Malicious Websites/Ads: Visiting compromised websites or clicking on malicious ads can also trigger a ransomware download.
   • Exploiting Vulnerabilities: Attackers may exploit vulnerabilities in outdated software or operating systems to gain access and install ransomware.
2. Execution:
   • Once on the system, the ransomware executes and begins to spread. It often attempts to disable antivirus and security software to avoid detection.
   • It may also attempt to move laterally across a network, infecting additional systems and maximizing the scope of the attack.
3. Encryption:
   • The ransomware starts encrypting files on the infected system, including documents, databases, images, and other critical data. It uses strong encryption algorithms, making the files inaccessible without the decryption key.
   • Some ransomware variants also target backup files to prevent the victim from restoring their data without paying the ransom.
4. Ransom Demand:
   • After encryption, the ransomware displays a ransom note, often on the victim’s desktop, demanding payment in cryptocurrency (like Bitcoin) for the decryption key.
   • The note typically includes instructions on how to make the payment, a deadline, and threats of permanently deleting the data or increasing the ransom if payment is not made within the specified time.
5. Payment and Decryption (if the ransom is paid):
   • If the victim pays the ransom, the attackers may provide a decryption key or software to restore access to the encrypted data. However, there is no guarantee that paying the ransom will result in data recovery, and it often encourages further criminal activity.
   • Some ransomware attackers may also engage in “double extortion,” where they threaten to publicly release sensitive data if the ransom is not paid.
6. Post-Attack:
   • Even after the ransom is paid and data is decrypted, the victim’s system may still be compromised, leaving them vulnerable to future attacks. Additionally, paying the ransom does not remove the malware, and it may remain on the system or network.
   • Organizations often face significant downtime, loss of data, financial costs, and reputational damage as a result of a ransomware attack.

Preventative measures like regular backups, updated security software, user education, and network segmentation are critical to protecting against ransomware attacks. Contact to Synergy IT Solutions group to solve.
