Cyber threats don’t always announce themselves with flashing warning signs or locked screens. Some operate quietly in the background—stealing resources, driving up costs, and putting your business at risk without you even realizing it. One such threat is cryptojacking.

What is it?

Cryptojacking, also known as malicious cryptocurrency mining, occurs when hackers secretly use your computer, server, or mobile device to mine cryptocurrency. They embed malicious code into a device or network, allowing them to take advantage of its computing power.

The hacker earns cryptocurrency by solving complex mathematical problems, which can later be traded for money or other digital assets. Meanwhile, the business or individual whose device has been compromised is left dealing with the consequences.

Why Cryptojacking Is a Serious Problem

While cryptojacking doesn’t always steal data directly, it steals resources—and that can still be expensive. Impacts may include:

  • Slower systems and reduced productivity

  • Increased electricity and operational costs

  • Overheating devices and hardware damage

  • Network instability that can open the door to additional cyber threats

Over time, these issues can disrupt daily operations and result in costly repairs or downtime.

How Cryptojacking Happens

Cryptojacking often begins with a simple action, such as:

  • Clicking on a malicious link in an email

  • Visiting a compromised website

  • Downloading infected software or attachments

Once activated, the malicious script quietly runs in the background, using your device’s processing power to mine cryptocurrency while sending the profits directly to the cybercriminal’s digital wallet.

Signs Your Business May Be Affected

Because cryptojacking is designed to stay hidden, it can be difficult to detect. However, there are some warning signs to watch for:

  • Computer or laptop fans running constantly

  • Devices feeling hotter than normal

  • Rapid battery drain

  • Sluggish performance, freezing, or frequent crashes

If multiple devices on your network are experiencing these issues, it may be a red flag.

How Cyber Insurance Can Help

Cyber insurance is designed to help businesses respond to and recover from cyber incidents—including threats like cryptojacking. Depending on the policy, coverage may help with:

  • Business interruption losses caused by compromised systems

  • Costs to investigate and remove malicious software

  • Recovery expenses and expert cyber response support

As cyber threats continue to evolve, having the right coverage in place can make a significant difference when something goes wrong.

Are You Properly Protected?

Many businesses assume cyber incidents are covered under traditional policies—only to discover gaps when a claim arises. A cyber insurance review can help determine whether your current coverage addresses modern threats like cryptojacking.
