Ransomware has become one of the most significant cybersecurity threats. It can disrupt operations and cause long-term damage to a company’s brand and reputation. It can also result in lost productivity and financial losses from data loss and the inability to restore backups. The threat has evolved rapidly over the past decade.

Initially, ransomware targeted random users and demanded a few hundred dollars in cryptocurrency to unlock personal files, such as photographs or documents. As the attacks grew more sophisticated, criminal gangs became involved. They hired specialists to improve malware and exploit weaknesses in target systems. They marketed their services in illicit marketplaces and provided ransomware as a service (RaaS) to other cybercriminals.

A ransomware attack typically begins with a vulnerability in software or computing systems, such as an unpatched flaw in third-party code. Hackers then use multiple attack channels, including phishing emails and malvertising, to spread the malware and infect systems. Once the attackers gain access to a system, they conduct reconnaissance until they identify data considered valuable. They may then encrypt the data or, as some groups like Cl0p do, just steal it and expose it publicly if they are not paid.

The success of the ransomware model owes to its efficiency and profitability. Compared to other cyberattacks, ransomware is cheaper and faster to execute and offers more in terms of potential payout (especially when considering the relative value of cryptocurrencies). It is also difficult to trace attackers because they shift infrastructure frequently, and many rely on legitimate hosting providers and pay for services through the Dark Web.
