The Rising Risk of Ransomware Attacks on Organisations and How to Mitigate it
According to the 2022 SonicWall Cyber Threat Report, “ransomware volume increased 105% year over year and is up 232% since 2019.” With the risk of ransomware attacks continuing to rise, it’s crucial to shield your organization from these attacks to avoid unwanted financial fallout.
Ransomware attacks commonly target an organization’s file servers and databases using malicious code to encrypt files such as documents, images, and videos on the system. Ransomware can also be programmed to find vulnerabilities on the network and use these to spread to other systems in an organization. Ransomware attacks are typically executed through social engineering like widespread phishing attacks, but cybercriminals can also specifically target a certain entity, sometimes a popular one. These attacks have the potential to cripple an entire organization’s database.
Once encrypted by ransomware, files are almost impossible to retrieve without the decryption key. To get this key, the victim is demanded to pay a ransom—often millions of dollars—within a short timeframe, usually 24 to 48 hours. If the victim organization keeps a backup of its files, then it’ll be able to restore those files and avoid paying the ransom. If not, the organization often has no option but to pay the ransom.
However, if you fall victim to a ransomware attack, it’s strongly recommended that you don’t pay the ransom to regain access to your encrypted files. This is because you are relying on the integrity of a cybercriminal. The cybercriminal may not give you the decryption key after the transaction or, even worse, they may continue to target your organization and repeatedly demand higher ransoms now that they know you’re willing to pay.
In recent years, it has become much easier to develop ransomware, resulting in the continued rise in ransomware attacks. Cybercriminals can develop and execute a ransomware attack with readily available open-source code and with easy-to-use drag-and-drop platforms. It is also hard to track these cybercriminals because transactions involving ransomware are commonly made using cryptocurrency.
Ransomware attacks can result in exploitation and loss of your organization’s critical and confidential data. But there are steps you can take to prevent and mitigate these attacks.
Back-Up Your Data
Take regular backups of all your files and data; this way, even if your system is infected, you can erase the infected files and recover them using your backups. This cannot prevent a ransomware attack, but it can mitigate the risk of losing all your data.
Keep Your System and Software Up-to-Date
Maintain a healthy patching routine. This includes updating your software as soon as possible when patches for security vulnerabilities are released by vendors. To keep your device secure from ransomware attacks, use a security solution that can identify these attacks at their earliest stages and mitigate their impact.
Be Careful Where You Click
Beware of social engineering attacks and email scams, and avoid downloading files from untrusted sources as these can result in your system being exploited by malicious software like ransomware. What makes social engineering attacks so dangerous is that they take advantage of human error rather than system vulnerabilities.
Create Awareness Among Employees About Ransomware Attacks
Since human error is a major vector cybercriminal manipulate to carry out ransomware attacks, it is essential to educate and train employees on social engineering and email phishing attacks to effectively secure your organization against them.
ManageEngine’s security information and event management (SIEM) solutions protect your enterprise network from cyberattacks and insider threats. SIEM solutions collect and analyze the security data generated by your devices in real-time, alerting you about vulnerabilities, indicators of compromise, and any suspicious activity to help you mitigate the risk of ransomware attacks.
