The Rising Threat to Houston Businesses: How Business Email Compromise Fuels the 123% Surge in Ransomware Attacks
Email Compromise Today, Ransomware Tomorrow: Stop the Cycle – Preventing BEC from Becoming Ransomware
Ransomware attacks rose 123% in two years, and most start with a compromised email account. Here is the chain - and how to break it.
Most ransomware does not blast its way in - it walks in through a compromised email account, then spreads before detonating.
It is tempting to picture ransomware as a sudden explosion. In practice it is the last step in a patient sequence that usually starts in an inbox. Business email compromise gives attackers the quiet access they need to learn your business and reach your most valuable systems. Understanding that chain is the key to stopping it, because every link is a place you can cut.
How BEC Becomes Ransomware
Four steps turn a hacked inbox into an encrypted network.
Attackers compromise an email account, spend time on reconnaissance, spread through the network, then deploy ransomware and steal data.
The dangerous part is the middle. Because the attacker is using a real, trusted email account, their early activity looks like normal business - which is why they can linger long enough to find the systems whose loss would hurt most. By the time ransomware appears, they have already done their homework.
Why It Works So Well
The numbers explain why criminals keep using this playbook.
Email fraud is now the leading source of cyber claims, and small businesses absorb most of the damage.
- Ransomware is surging. Black Kite's 2025 Ransomware Report recorded a 123% increase in attacks over two years, driven by a 25% year-over-year jump on top of an earlier 81% spike.
- Email fraud leads the claims. Coalition's 2025 Cyber Claims Report found business email compromise and funds-transfer fraud together drove 60% of all 2024 claims, and 29% of BEC events led to funds-transfer fraud.
- The losses are real. Coalition put the average BEC loss around $35,000 and the average ransomware loss near $292,000 per incident - and when a BEC escalates to ransomware, those costs stack.
- Small businesses take the hit. Coalition reported that companies under $25 million in revenue represented the majority of total claim costs in 2024.
Ransom payments are only one line on the bill. Business interruption, data restoration, and forensic investigation often cost more - which is why prevention pays for itself many times over.
How to Break the Chain
You do not have to stop every step - cutting any one link stops the attack.
Layered email and network controls block the compromise, the spread, and the payload - and let you recover if one slips through.
- Turn on MFA everywhere. Multi-factor authentication on every email account - especially executives and finance - stops most account takeovers even when a password leaks.
- Train staff to spot phishing. Regular, realistic training turns the people attackers target into the ones who report the attempt.
- Filter email at the gateway. Advanced email security quarantines malicious messages before they reach an inbox.
- Run endpoint detection (EDR). EDR flags the unusual account behavior and lateral movement that signal an intruder mid-chain.
- Keep offline, tested backups. Backups separated from the network let you restore without paying if ransomware does deploy.
- Segment the network. Least-privilege access and segmentation limit how far a compromised account can reach.
- Test an incident response plan. A rehearsed plan for both BEC and ransomware turns a crisis into a contained event.
The reason business email compromise is so effective is that nothing looks broken. The attacker is logged in as a real employee, reading real email, waiting. By the time the ransomware note appears, they have owned your network for weeks. MFA and monitoring are how you shorten that window to nothing.

Frequently Asked Questions
What is business email compromise (BEC)?
BEC is an attack where a criminal gains access to or convincingly impersonates a business email account - usually through phishing, social engineering, or stolen credentials - to commit fraud or gain a foothold in the network. It is frequently the first step that leads to funds-transfer fraud or ransomware.
How does BEC lead to ransomware?
Once inside an email account, attackers quietly read messages to understand the business, move laterally into other systems, and then deploy ransomware - often stealing data first so they can threaten to leak it. The compromised inbox provides the trusted access that makes the rest possible.
How much have ransomware attacks increased?
Black Kite's 2025 Ransomware Report found a 123% increase in ransomware attacks over two years, including a 25% year-over-year rise on top of an earlier 81% surge in publicly disclosed victims.
Are small businesses really targeted?
Yes. Coalition's 2025 Cyber Claims Report found businesses under $25 million in revenue carried the majority of total claim costs in 2024. Smaller companies often have valuable data but lighter defenses, which makes them attractive targets.
What is the single most effective defense against BEC?
Multi-factor authentication on every email account is the highest-value control, because it blocks most account takeovers even when a password is stolen. Pair it with staff training and email filtering for defense in depth.
