Ransomware Attacks Surge: How Hackers Are Utilizing Public and Legitimate Tools
Ransomware attacks are on the rise and they are becoming increasingly sophisticated. In fact, according to recent statistics, these attacks have surged by 350% in 2020ย alone. This means that businesses and individuals are at a higher risk now more than ever before. But what exactly is ransomware and how are hackers utilizing public and legitimate tools to carry out these attacks?
What is Ransomware?
Ransomware is a type of malicious software that encrypts files on a computer or network, rendering them inaccessible to the user. The attackers then demand a ransom in exchange for the decryption key, which will unlock the files and restore access. These attacks can have devastating consequences for businesses, as they can lead to data loss, financial loss, and damage to reputation.
The Role of Public and Legitimate Tools
Traditionally, ransomware attacks were carried out using custom-built malware. However, hackers have now shifted their tactics and are utilizing public and legitimate tools to carry out these attacks. This makes it harder for organizations to detect and prevent these attacks, as the tools used are widely available and can blend in with normal network traffic.
The most commonly used tools in ransomware attacks are Remote Desktop Protocol (RDP), PowerShell, and Cobalt Strike. RDP is a legitimate tool that allows users to remotely access computers on a network. However, if RDP is not properly secured, it can be exploited by hackers to gain access to a network and deploy ransomware. Similarly, PowerShell is a legitimate scripting language used for system administration, but it can also be abused by hackers to download and execute ransomware. Cobalt Strike, a legitimate penetration testing tool, can also be repurposed by attackers to evade detection and deliver ransomware.
How to Protect Against Ransomware Attacks
As the use of public and legitimate tools in ransomware attacks continues to rise, it is crucial for organizations to take steps to protect themselves. Here are some actionable takeaways to help mitigate the risk of ransomware attacks:
- Regularly back up critical data and store it offline.
- Keep all software and operating systems up to date with the latest security patches.
- Implement multi-factor authentication for all remote access tools.
- Restrict RDP to only known and trusted IP addresses.
- Monitor network traffic for suspicious activity, such as large file transfers or unusual processes.
- Educate employees on how to identify and report suspicious emails or links.
In Conclusion
Ransomware attacks are a serious threat to businesses and individuals alike. With the use of public and legitimate tools, hackers are becoming more elusive and it is becoming harder to detect and prevent these attacks. However, by implementing the above measures and staying vigilant, organizations can better protect themselves from falling victim to ransomware attacks.
