How to Recover From a Ransomware Attack

Cybercriminals are increasingly using ransomware to extort payments from organizations, with Verizon reporting that it was involved in 44 percent of all breaches — a sharp rise from the previous year. Ransomware attacks can disrupt operations, impact revenue and damage customer trust, pointing to the need for stronger defenses, including clear protocols and advanced threat detection systems.

Understanding how to recover from a ransomware attack begins with knowing the different types of information security essential to building a strong defense strategy. Skilled professionals are critical to this effort, and demand for cybersecurity roles continues to grow. According to the U.S. Bureau of Labor Statistics (BLS), information security analyst roles are expected to increase by 33 percent from 2023 to 2033.

Earning an advanced degree such as a Master of Science in Cybersecurity Management and Technology (MSCMT) can help professionals develop the expertise needed to protect systems; respond to threats such as ransomware; and advance in a high-growth, high-impact field.

What Is a Ransomware Attack?

Ransomware, a type of malware, blocks access to a user’s files, systems or networks until payment is made to get them back. It can spread through phishing emails, infected websites or hidden software vulnerabilities. In some cases, the attackers threaten to leak or destroy the data. These attacks usually happen in stages. After gaining access to a system, attackers encrypt personal data, lock the user out and demand payment.

Types of Ransomware Attacks

Recovering from a ransomware attack can be complex because ransomware is always evolving. In 2024, the FBI’s Internet Crime Complaint Center (IC3) found 67 new ransomware variants. This number represents a small fraction of variants in existence, with some estimates noting thousands of ransomware families and offshoots. Many can be categorized under the types of ransomware attacks in the sections below.

Crypto Ransomware

Crypto ransomware moves fast, encrypting the victim’s files and locking them out. Once the system is infected with the malware, the victim will lose access to critical data. A decryption key can provide access, and the attacker offers it to the victim if they pay a ransom, typically in cryptocurrency. However, even after the victim pays the ransom, there’s no guarantee that they’ll get their files back.

Lockers

Locker ransomware prevents victims from accessing their devices. It sneaks in through ads, phishing emails or fake apps, oftentimes disabling controls. The primary difference is that locker ransomware doesn’t encrypt files. Victims typically see a lock screen asking for payment, with disabled controls and often a countdown timer to encourage quick action.

Scareware

A scareware tactic might involve an attacker posing as law enforcement. Scareware software floods the screen with fake warnings about crimes, which can create a sense of fear among users. Unlike other ransomware, scareware doesn’t usually encrypt files — it manipulates people into acting fast, using pop-ups and urgent messages to trick them into handing over money or personal data.

Doxware

Doxware, also known as leakware, is used to steal files and threaten to expose sensitive information unless a fee is paid. This kind of attack is especially dangerous for businesses that handle private customer data or financial records, leading to a loss of trust among their customers. Some variants even impersonate law enforcement, warning of jail time unless a fine is paid.

Ransomware as a Service

With ransomware as a service (RaaS), anyone can launch a ransomware attack by buying ready-made tools from professional hackers. These attackers handle everything behind the scenes, from spreading the malware to collecting payments, while taking a cut of the ransom. This plug-and-play model is driving a surge in attacks, putting more organizations at risk.

Tips for Recovering From Ransomware Attacks

Although paying a ransom may seem like the quickest path to recovery, doing so poses significant risks. There’s no guarantee that attackers will restore access or delete stolen data, and payment may incentivize further criminal activity. Law enforcement agencies and cybersecurity professionals consistently advise against paying.

Response and recovery focus on reducing harm and restoring normal activity more efficiently by following a structured approach. As for how to recover from a ransomware attack, the steps below might be helpful.

Detect and Analyze Early Signs

Initially, security teams assess the scale of the incident by identifying which systems are most critical to operations and whether any have been compromised. Reviewing logs from antivirus and intrusion systems may reveal anomalies: new user accounts, elevated permissions or remote access from an unknown source.

Communicate and Report

Internal teams —including information technology (IT), security staff, and department heads — and external partners such as vendors and insurance providers should receive timely updates on the situation. Senior leaders benefit from regular briefings to support decision-making. Reporting the attack to authorities such as the Cybersecurity and Infrastructure Security Agency (CISA), the FBI or theSecret Service is a critical step, even if the attack was stopped early or a ransom was paid.

Contain the Threat

Once an attack is discovered, containing the spread of ransomware is a top priority. Common steps to stop the malware from spreading are disconnecting affected systems from networks; removing external drives; and disabling remote access features, including virtual private networks (VPNs) and single sign-on (SSO) platforms. Resetting passwords and reviewing exposed vulnerabilities help secure systems and prevent further unauthorized access.

Eradicate Malware

Trusted antimalware tools can identify and eliminate the malicious code. In some cases, these tools can detect the specific ransomware strain or assist with limited decryption. If full system integrity is in doubt, wiping the hard drive and reinstalling the operating system may be necessary to ensure a clean recovery environment.

Restore and Recover

Restoration should begin only after systems are verified to be free of malware. Any compromised data should be isolated before attempting recovery. When available, decryption tools from trusted security researchers or law enforcement may provide access to encrypted files without payment. When necessary, clean backups that have been stored securely on external or cloud-based platforms can be used to restore operations.

Learn and Strengthen Defenses

Revisiting what happened and updating response plans, patching vulnerabilities and reviewing access controls are all part of strengthening future defenses. To stay ahead, businesses should continually monitor network activity closely, invest in threat detection tools, and train employees to recognize phishing attempts and suspicious links.

Sharpen Your Expertise in Cybersecurity

According to the IC3, ransomware was the most common threat to critical infrastructure in 2024, with reported cases rising by 9 percent from the year before. As cyber threats such as ransomware continue to evolve, organizations must take a proactive approach to managing vulnerabilities.

Professionals with expertise in information security management can assess risks and implement safeguards — skills that are also in demand for homeland security careers.
