The 3 Most Common Cybersecurity Attacks in 2025
In 2025, cybersecurity threats aren’t just targeting big banks or federal agencies they’re hitting closer to home. From ransomware attacks that crippled Winston-Salem’s city systems to AI-powered phishing scams deceiving Charleston nonprofits, cybercriminals are proving that no organization is too small or too local to be a target. Business Email Compromise (BEC) schemes are silently draining funds from small businesses, often without detection until it’s too late. Whether it’s encrypted files, deepfake voicemails, or hijacked email threads, the threat landscape in Winston-Salem and Charleston has never been more aggressive or more personal.
At Kotori Technologies, we’ve spent the last two decades helping businesses across the Carolinas stay ahead of the curve. And this year, the curve is steep. Let’s break down the three most common cybersecurity attacks we’re seeing in 2025 and what you can do to protect your business.
What Does “The Curve Is Steep” Really Mean?
When we say the cybersecurity curve is steep in 2025, we’re talking about the rate of change in both attack sophistication and frequency. Cybercriminals are no longer relying on outdated malware or generic phishing emails. They’re using AI to automate reconnaissance, mimic human behavior, and launch targeted attacks that adapt in real time. For small and mid-sized businesses in Winston-Salem and Charleston, this means the window between “new threat discovered” and “new threat exploited” is shrinking fast. Defenses that worked last year may already be obsolete.
Ransomware: Still King of the Hill
In January, Winston-Salem’s city services were knocked offline by a ransomware attack that disrupted everything from utility payments to internal communications.
This wasn’t a one-off. Ransomware remains the most common cybersecurity attack in 2025, and it’s evolving. Today’s variants don’t just lock your files they steal them, threaten to leak them, and sometimes skip the ransom altogether just to cause chaos.
For small businesses, the risk is real. One compromised laptop can lead to days of downtime, lost revenue, and a damaged reputation. And in cities like Charleston, where tourism and hospitality rely on uptime and trust, the stakes are even higher.
Today’s Ransomware: Smarter, Quieter, and More Ruthless
Ransomware in 2025 isn’t just about locking files and demanding Bitcoin. According to Forbes attackers are now using AI-powered social engineering to gain access through voice phishing (vishing), where synthetic voices mimic executives or IT staff to trick employees into handing over credentials.
Even more alarming, many ransomware groups have shifted to “steal now, encrypt later” tactics. They quietly exfiltrate sensitive data, then threaten to leak it unless a ransom is paid often without ever triggering traditional antivirus alerts. These low-volume, high-impact campaigns are designed to avoid media attention and law enforcement, making them harder to detect and even harder to stop.
AI-Powered Phishing: Smarter, Faster, Scarier
Gone are the days of broken-English scam emails. In 2025, phishing attacks are powered by generative AI. These emails are personalized, grammatically perfect, and often indistinguishable from legitimate communication. We’ve seen Charleston nonprofits and Winston-Salem law firms fall victim to emails that looked like they came from their own leadership teams.
These attacks are now the second most common cybersecurity threat and they’re getting harder to detect. AI can mimic writing styles, reference real events, and even generate fake invoices that match your actual vendors.
AI-Powered Phishing: The New Face of Deception
Phishing has always been a top threat, but in 2025 it’s evolved into something far more dangerous. Cybercriminals now use generative AI to craft emails that are indistinguishable from legitimate business communication. These messages are personalized, grammatically flawless, and often reference real meetings, invoices, or internal projects.
One of the fastest-growing threats is deepfake phishing, where attackers use AI-generated audio or video to impersonate company leaders. Imagine receiving a voicemail from your “CEO” asking you to approve a wire transfer it sounds exactly like them, but it’s a fake. This is no longer science fiction; it’s happening now, and it’s hitting businesses of all sizes.
Business Email Compromise (BEC): The Silent Killer
BEC attacks don’t make headlines, but they drain millions from small businesses every year. In 2025, attackers are using social engineering and AI to quietly infiltrate email threads, redirect payments, and impersonate executives. One Charleston-based franchise lost $48,000 in a single week after a fake “CEO” requested a wire transfer.
These attacks are subtle, often discovered too late, and increasingly common in industries like real estate, healthcare, and logistics sectors that thrive in both Winston-Salem and Charleston.
