Ransomware attacks are becoming more frequent and expensive, dealing irreparable damage to businesses of all sizes and industries by encrypting data and rendering it inaccessible until a ransom is paid to the perpetrator.
But while ransomware is a formidable foe, mitigating its impact is possible with early threat detection and swift response. Here’s how to identify the early signs of a ransomware attack and the crucial, immediate steps to take.
The first warning signs of a ransomware attack
Tune into the following telltale signs to recognize a ransomware attack before it’s too late:
Unusual network activity
Keep an eye out for unexpected spikes in network traffic and suspicious communication with unknown IP addresses. Ransomware often requires communication with command-and-control servers, which can result in unusual network activity patterns.
Suspicious emails and phishing attempts
Phishing emails are a common vector for ransomware delivery. Be cautious of emails with suspicious attachments or links, and always check for phishing indicators, including spoofed email addresses, spelling or grammatical errors, generic greetings, and requests for confidential data.

Unauthorized access and user anomalies
Monitor your network for unusual login attempts and suspicious user behavior. If you notice multiple failed login attempts or strange activities, investigate immediately. These could be signs of a ransomware attack in progress.
What to do if you suspect a ransomware attack
Identifying the early signs of a ransomware attack is crucial, but taking swift action is equally important to prevent further damage. Do the following as soon as you suspect that you’ve been hit by ransomware:
Isolate infected systems
Immediately disconnect the affected devices from the network and disable Wi-Fi or network access to prevent the infection from spreading. However, do not delete any evidence of the attack, including emails, files, or network traffic logs, as these are necessary for the investigation of the attack.
Contact your IT security team
Notify your IT department or security partner without delay. Provide them with as much information as possible about the suspected attack, including the time and date of the attack, the affected systems, and any unusual activity you have noticed.
Assess data backups
Check the availability and integrity of your data backups to ensure that they have not been compromised. If necessary, restore data from clean backups to minimize data loss.
Notify relevant authorities
Your business’s location or industry may legally obligate you to report the incident to relevant agencies. In Canada, for instance, you are required to notify your local law enforcement authorities and report the attack to the Canadian Anti-Fraud Centre.
Ransomware mitigation is good, but preventing an attack is better
Preventing a ransomware attack is always better than dealing with its aftermath. To protect your business from ransomware, consider implementing the following proactive measures:
- Regularly update software and patches – Keep your operating systems and software up to date to address vulnerabilities that cybercriminals may exploit.
- Train employees on cybersecurity – Educating your employees on social engineering tactics helps them recognize and report suspicious activities.
- Segment your networks – By partitioning your networks, you can stop the malware from moving throughout your organization.
- Implement multiple security solutions – Create a layered security approach that includes multiple solutions such as firewalls, data loss prevention solutions, and intrusion detection systems, to better detect and block malware attacks.
- Create an incident response plan – This plan must detail every employee’s role and appropriate response in the event of a ransomware attack. Regularly evaluate and enhance this plan to ensure it remains effective.
- Work with a trusted technology provider – Collaborate with a trusted technology partner, such as a managed IT services provider, to strengthen your cybersecurity defenses. Leverage their resources and expertise to proactively safeguard your systems and data.
