What to Do If Your Computer Has Been Hacked: Essential Steps for North London Businesses

In the  daily grind of running a small business, the last thing you want to worry about is the security of your computer systems. Yet, in the shadows of uncertainty, the question lingers: has your computer been compromised?

According to IBM’s latest cybersecurity report, the average data breach goes 277 days before it’s noticed and reported.

Fear not, in this article you’ll learn how to tell if your computer or other device has been hacked and what to do about it. As you delve into the following sections, you’ll discover the essential steps to alleviate those concerns and safeguard your business against digital threats.

Recognising the Red Flags

How to know if your computer is hacked?

It’s a question that might keep you up at night. The tell-tale signs are often subtle, but ignoring them could be costly. Here’s what to look out for:

  • Unusual Slowness or Crashes: If your computer or network suddenly becomes sluggish or crashes frequently, it’s time to investigate.
  • Pop-up Overload: An onslaught of pop-ups is not just annoying—it could indicate a security breach.
  • Locked Out? If you find yourself unable to access user accounts, it’s a red flag that someone else might be in control.
  • File Frenzy: Unexpected file changes or system behaviours, such as your computer running post-shutdown, are warning signs.
  • Strange Account Activities: Keep an eye out for any abnormal activity on your accounts.

What to Do If Your Computer Has Been Hacked?

Discovering a hack can be alarming, but your response can make all the difference. Here’s what to do:

Isolate, Don’t Reboot

When you suspect a breach, immediately isolate your computer from the network to prevent the spread of malware. Resist the urge to reboot, as this could initiate encryption processes by certain types of malware, leading to data loss.

Keeping the device on allows IT professionals to better analyse and address the issue.

Call the Pros

Time is of the essence. Contact your IT service provider without delay. They have the expertise to assess the situation, contain the breach, and start the recovery process. Attempting to resolve the issue yourself may inadvertently exacerbate the problem.

Get Legal Counsel

In the event of a security breach, it’s crucial to understand the legal ramifications. Reach out to your solicitor for guidance on compliance with data protection laws and to prepare for any potential legal actions that may arise from the breach.

Secure Your Accounts

While your IT team handles the technical side, take proactive steps to secure your online presence. Change passwords across all accounts, prioritising those with financial or sensitive information. You can also implement multifactor authentication to add an extra layer of security.

Monitor Financials

Keep a vigilant eye on all financial transactions and account activities. Early detection of any unauthorised access or anomalies can be critical in mitigating financial repercussions of a cyber attack.
