Ransomware is a type of malicious software designed to gain access to files and encrypt data, making it inaccessible without a decryption key. This key is typically stored on the attacker's server until a ransom is paid. Unfortunately, even after payment, victims often find that the decryption key is not provided, leaving them without their files and their money. The global cost of ransomware was estimated at over $20 billion in 2021, highlighting its significant impact on organizations.

Ransomware attacks are on the rise due to several factors, including the clever techniques used by hackers to evade security software, resulting in the creation of 'Zero-Day Malware.' Additionally, the use of the Tor network and cryptocurrencies like Bitcoin makes it difficult for law enforcement to trace these cybercriminals. Reports indicate that ransomware infections increased by over 300% year over year, with many attacks targeting businesses that are more likely to pay ransoms to recover their critical data.

Organizations can protect themselves from ransomware by implementing strong cyber hygiene practices, such as keeping antivirus software up to date and educating users about phishing attacks. Regular and granular data backups are crucial, as traditional backup methods may not provide sufficient protection. In the event of an attack, solutions like the Zerto platform can help organizations quickly recover their systems to a point before the infection, minimizing data loss and downtime.
