One of the most common ways ransomware spreads is through phishing e-mails.
Ransomware can spread in many different ways. This is when the malicious actors in your environment steal data from you and threaten to release it unless you pay the ransom. Another increasingly common type of ransomware attack is exfiltration. The ransomware attack we often think about is data encryption. The malicious actors go a step further and look for data about an organization’s customers and suppliers, to then target them. A triple extortion attack is where machines are encrypted and data is stolen. A double extortion attack is where ransomware not only encrypts your data but steals it. There are also double and triple extortion attacks. There are several different types of ransomware attacks, with the most classic one being data encryption. What are the different types of ransomware attacks? Not familiar with Cybersecurity Incident Responses? Be sure to take a look at the Cybersecurity Incident & Vulnerability Response playbooks recently published by CISA. The HOW of ransomware recovery will depend on what is determined during the Detection & Analysis phase, so it is important to have multiple recovery strategies in place, and thoroughly tested. This process can be a bit different from what most backup administrators are used to when it comes to restoring data.īefore you can recover from ransomware, there are a number of phases of the incident response plan that must be completed, such as Detection & Analysis, Containment, and then Eradication & Recovery. The first step is engaging your IT security team so they can begin their incident response process. One of the most confusing aspects of ransomware is often what happens after an attack occurs. What does recovery after a ransomware attack look like? After encryption, you will need to restore to a previous backup.ĭepending on how long the ransomware sat idle on your system, you will also want to scan the restored system to ensure you are not introducing the threat back into the environment. This backup becomes critical after machines have been encrypted. The first thing to do to protect your data from ransomware is to ensure you have a recent, successful backup. Unfortunately, many organizations don’t feel confident in the recovery process, which is why it’s important to take the steps to ensure your environment can recover from ransomware. The most pressing question from most IT organizations these days is, “Can I recover from ransomware?” Recovery is almost always possible. Can systems impacted by ransomware be recovered?
Once a ransomware event happens, you will be able to ensure your antimalware systems have the proper definitions to detect the ransomware variant you have been impacted by.

While the ransomware software itself must be removed from encrypted machines, steps must also be taken to determine how the attackers got in and mitigate those attack vectors. Can ransomware be removed?ĭuring the cybersecurity incident response process, steps will be taken to evaluate how the ransomware got into the environment and how systems have been impacted, beyond just the encryption of data. At this point, steps can be then taken to eradicate the ransomware, remove the vulnerabilities that allowed the attackers in, and restore impacted systems. While this is a big part of ransomware recovery, there are also wider impacts to the rest of your IT environment.įorensic analysis is conducted as part of the cybersecurity incident response to determine how the ransomware got into the environment and what systems it has infected. In the data protection space there is a huge focus on recovery, especially recovering encrypted VMs from backup. Recovery can be simple, it can follow many of the existing disaster recovery processes you have today, provided your disaster recovery plans are well documented and thoroughly (and recently) tested. Ransomware data recovery is the process followed to bring IT systems back online after a ransomware attack. Did you know that only 65% of data is recovered during a ransomware attack according to Sophos’ State of Ransomware study? Today, we’re going to take a deep dive into some of the most commonly asked questions about recovering from ransomware and things that everyone should know before they are hit by it.
