Recovering From a Cyberattack: How Businesses Can Build Resilience and Prevent Future Security Breaches

Being a victim of a cyberattack can be devastating for businesses and individuals as it can cause data loss, reputational issues, and financial damage.

It is estimated that nearly 60 percent of businesses were hit by ransomware in 2024, while there were over 930,000 phishing attacks in the third quarter of the same year. As people have come to rely more on digital platforms, expect cybercriminals to be even more relentless as they explore various ways to accelerate attacks. In fact, experts predict that by the end of 2025, there will be a number of widescale threats that could take place, including a supply chain attack that could affect 45 percent of global organizations.

Many small businesses have found it difficult to recover from the effects of a data breach, but if your company has recently experienced a cyberattack, there are actionable steps that you can take to recover and prevent it from happening again. Here’s how to build resilience and prevent future security breaches after a cyberattack

Learn to Recognize Signs of a Cyberattack

Many hackers tend to go for the same targets, especially if previous breaching attempts have been successful. To thwart cybercriminals, everyone in your organization must learn how to recognize common signs of a cyberattack. For instance, if your team is having trouble accessing certain files or software, take that as a red flag since this is a sign of ransomware. Experts define ransomware as a malware used by cybercriminals to encrypt files on a device or system and make them inaccessible until a ransom is paid. Having your files locked can disrupt your operations, so report it immediately to your IT specialists.

Be on the lookout for unexpected or unscheduled reboots, as well as a sudden increase in traffic as these could be due to a malware attack. Also, if you get notices for multiple failed log-ins, or if your team has been getting emails with suspicious links, it’s likely that a threat actor is attempting credential theft or a phishing attack.

Keep Things Under Control

Actions taken in the aftermath of a cyberattack can help to minimize the damage and prevent other hackers from attempting to breach your systems. Once you’ve spotted the signs of a cyberthreat, take steps to keep things under control. Contain the breach by changing passwords, then use a password manager to create strong and unique passwords for each account. Install updates and patches, then disable remote access to your system. Don’t forget to disconnect your Internet to prevent other servers and devices from being compromised.

At this point, you’ll need to identify the source of the breach. Find out how the attack was initiated by checking the data logs on your email providers and firewall. You should also know who has access to the devices and servers that were infected, and identify who were affected by the breach. It’s likely that information about your customers or third party vendors may have also been stolen from your systems, so find out if sensitive data like birthdays, social security numbers, or contact information were accessed during the attack. For the sake of transparency, inform your customers and business partners about the breach, and train your customer service team how to respond to questions from affected parties.

Amp up Your Cybersecurity Measures

After a cyberattack, you’ll need to amp up your cybersecurity measures to prevent future data breach attempts. Change passwords regularly, and always keep systems and apps up to date. Cultivate a culture of cybersecurity by educating staff on best practices, such as safe browsing and being wary of unsolicited calls, emails, or text messages. You may also want to consider incorporating advanced detection tools into your system to detect and stop threats in real time.

A cyberattack can occur anytime, and anyone can become a victim of malware, phishing, or ransomware. Be proactive when dealing with data breaches, and prioritize cybersecurity to protect your business and customers. In case of a severe attack, contact cybersecurity experts to guide you through the recovery process and help you strengthen your defenses against all kinds of cyber threats.
