Ransomware Crisis at Nova Scotia Power: What the Attack Means for Customers and How to Stay Protected

Imagine opening your next electricity bill and wondering: “Is this number even real?” That’s the reality facing hundreds of thousands of Nova Scotia Power customers after a sophisticated ransomware attack halted meter data collection and exposed sensitive personal information—including bank account numbers. In this post, I’ll break down what happened, what it means for your privacy and wallet, and practical steps you can take right now to protect yourself.

Let’s demystify the chaos, clarify what Nova Scotia Power is doing, and—most importantly—help you stay one step ahead of the scammers exploiting this cyber crisis.

What Happened? Understanding the Nova Scotia Power Ransomware Attack

On April 25, 2025, Nova Scotia Power, a major Canadian electricity provider, discovered it had fallen victim to a complex ransomware attack. In plain language, ransomware is malicious software that locks down computer systems and demands money to restore access. But this attack went further—it disrupted critical operations and led to a serious data breach.

The Immediate Impact: Meter Readings and Billing Disrupted

Although your home or business meter still tracked your electricity usage during the attack, the key problem was communication. The meters couldn’t send their readings to Nova Scotia Power’s systems. It’s a bit like your smart thermostat working fine, but the app on your phone can’t see what it’s doing.

This digital disconnect meant:

Billing was paused for a period after the attack.
Now, most customers are receiving estimated bills instead of charges based on actual usage.
The company is working with cybersecurity experts to restore normal operations, but there’s no timeline for full recovery yet.

This isn’t just an inconvenience; it ripples out to budgeting, customer trust, and the utility’s own finances.

Data Breach: What Information Was Stolen?

For many, the most unsettling news isn’t about billing at all—it’s that hackers accessed and stole sensitive customer data. On June 6, Nova Scotia Power confirmed that approximately 280,000 customers were affected.

What Kind of Data Was Compromised?

The stolen information varies per customer, but could include:

Full names, dates of birth, and contact details
Mailing and service addresses
Driver’s license and Canadian Social Insurance numbers
Account history, billing, and credit records
Bank account numbers (if you provided this info)

Worse, Nova Scotia Power has confirmed that some of this stolen data has already been posted to the dark web—a shadowy corner of the internet where cybercriminals buy and sell personal information.

Why Does This Matter to You?

If your info is among the leaked data, you’re at higher risk of:

Identity theft (using your info to open accounts or take out loans)
Phishing scams (fraudsters pretending to be Nova Scotia Power)
Financial fraud (if your bank details were exposed)

Let’s pause here: This isn’t just a hypothetical threat. According to Canadian Anti-Fraud Centre, victims of data breaches are often targeted by criminals within weeks.

How Did the Attack Happen?

Nova Scotia Power hasn’t shared exactly how hackers infiltrated its systems. This is common in ongoing investigations. However, based on industry trends and similar incidents, attackers often exploit:

Phishing emails that trick employees into clicking malicious links
Outdated software with known vulnerabilities
Weak or reused passwords across critical systems

The attackers gained access around March 19, 2025, but the breach wasn’t discovered until April 25—over a month later. This delay is typical in ransomware cases, as criminals often lurk undetected before launching their attack.

Nova Scotia Power’s Response: What Are They Doing?

When a crisis hits, how a company responds is just as important as what happened. Nova Scotia Power has taken several steps:

1. Pausing and Then Estimating Billing

Why estimate bills? Without real meter data, the company uses historical averages to estimate usage. This ensures cash flow and keeps the lights on for everyone, but it isn’t ideal for accuracy.
What if my estimate is wrong? Once systems are restored, your next bill will be corrected based on actual usage data. Overcharges or undercharges should even out.

2. Working with Cybersecurity Experts and Authorities

The company has engaged external cybersecurity teams and is cooperating with law enforcement. Transparency has been a priority—they’re providing regular updates via their official incident page.

3. No Ransom Payment

Nova Scotia Power refused to pay the ransom. This aligns with global law enforcement guidance (RCMP) and best practices, as paying can fund further criminal activity and doesn’t guarantee data restoration.

4. Customer Protection Measures

Expanding credit monitoring services to affected customers
Notifying those whose most sensitive data may have been compromised
Warning customers to watch for scams impersonating Nova Scotia Power

What Does This Mean for Customers? The Real-World Impact

If you’re a Nova Scotia Power customer, this attack affects you in several ways:

1. Temporary Billing Uncertainty

Expect estimated bills until the company’s systems are fully restored.
If you rely on precise monthly budgeting, keep an eye on corrections in future bills.

2. Increased Risk of Fraud and Scams

With personal information exposed, criminals may try to trick you through fake calls, emails, or texts.
Scammers might pose as utility employees, claiming to “fix” your account or “verify” your details.

3. Emotional Stress

Worrying about your financial security and privacy is exhausting.
It’s natural to feel angry, anxious, or let down. You’re not alone—data breaches are on the rise globally.

What Should You Do Now? 7 Steps to Protect Yourself

Here’s a practical action list for customers whose data may have been compromised:

Watch for official communication
Nova Scotia Power will contact affected customers directly. Double-check the sender’s address and look for official branding.
Sign up for credit monitoring
Take advantage of free credit monitoring if offered. This helps detect suspicious activity on your credit report.
Change your passwords
Update passwords for your utility account, online banking, and any related logins. Avoid reusing the same password across sites.
Monitor your bank accounts
Check statements for unauthorized transactions. If you spot something suspicious, contact your bank immediately.
Be wary of phishing
Nova Scotia Power will never ask for your password or banking details over the phone or via email. If in doubt, hang up and call the company directly through its official number.
Request a credit freeze or fraud alert If you believe your Social Insurance Number was exposed, consider placing a fraud alert or credit freeze with credit bureaus like Equifax Canada or TransUnion Canada.
Stay informed Follow updates from Nova Scotia Power and reputable news sources. Cybersecurity incidents evolve quickly.

Ransomware: A Growing Threat to Critical Infrastructure

While this attack is alarming, it’s sadly not unique. Ransomware targeting utilities and critical infrastructure is surging worldwide.

Why Are Utilities Attractive Targets?

Utilities hold:

Massive volumes of personal and financial data
Critical infrastructure—society can’t function without electricity
Perceived willingness to pay—restoring services quickly is a high priority

Recent ransomware attacks have hit water utilities, hospitals, and even entire cities. For a deeper dive, the Government of Canada’s cybersecurity reports provide valuable context.

The Dark Web: Where Stolen Data Goes

When Nova Scotia Power confirmed that some customer data had been posted to the dark web, it raised new concerns.

What Is the Dark Web?

Think of the internet as an iceberg:

The surface web is what you use every day (Google, news sites).
The deep web includes private databases and password-protected content.
The dark web is a hidden part, accessible only with special browsers—where criminals buy and sell stolen information.

If your data is on the dark web, it may be bought and used for future scams or fraud. That’s why vigilance is crucial—even if nothing has happened yet, your information could be misused months or years down the line.

Could This Have Been Prevented? Lessons in Cybersecurity

No system is invulnerable, but experts agree that robust cybersecurity can make attacks less likely and less damaging.

Key Defenses Include:

Regular software updates to patch vulnerabilities
Employee training to spot phishing attempts
Network segmentation to limit access if hackers breach one area
Frequent backups so data can be restored without paying ransoms

If you’re a business owner or IT leader, let this incident be a wake-up call to review your own cyber hygiene.

Nova Scotia Power’s Commitment: What Comes Next?

The company says it’s sparing no effort to resolve the incident. Here’s what they’re focused on:

Restoring full meter communication and billing accuracy
Notifying and supporting all affected customers
Enhancing their cybersecurity defenses to prevent future attacks

While it’s frustrating to wait for normal service, transparency and customer support are key to rebuilding trust. If you have questions or need assistance, don’t hesitate to contact Nova Scotia Power directly.
