Ransomware is still one of the biggest threats to small and medium businesses (SMBs), and it’s not slowing down anytime soon. Attackers are getting smarter, and businesses that think “it won’t happen to us” are often the ones hit hardest. So, let’s break down the top 5 ransomware threats that you need to be aware of right now.
1. LockBit 3.0 – The ‘Professional’ Ransomware
LockBit has been around for a while, but version 3.0 has taken things to another level. It’s fast, efficient, and now operates like a full-on business, even offering ‘bug bounties’ for hackers who find weaknesses in their system. If that’s not bad enough, LockBit doesn’t just encrypt your data—it also steals it, threatening to leak sensitive information if you don’t pay up.
How it spreads: Phishing emails, compromised remote desktop connections (RDP), and software vulnerabilities.
How to protect your SMB: Regularly update software, use strong passwords (with multi-factor authentication), and train staff to spot phishing attempts.
2. BlackCat (ALPHV) – The Newcomer with a Twist
BlackCat is a rising star in the ransomware world. What makes it unique? It’s written in Rust, which makes it harder to detect and analyse. This ransomware-as-a-service (RaaS) model means cybercriminals can ‘rent’ the software and launch attacks with minimal effort.
How it spreads: Compromised credentials, unpatched software, and brute-force attacks.
How to protect your SMB: Disable unused remote access points, enforce strong password policies, and consider a zero-trust security approach.
3. Cl0p – The Data Extortion Specialist
Cl0p doesn’t just encrypt your files—it steals them first. This means even if you have backups, the attackers can still blackmail you by threatening to release sensitive data online. Recently, Cl0p has been targeting large organisations, but SMBs aren’t safe either.
How it spreads: Phishing emails, vulnerabilities in file transfer services, and malicious email attachments.
How to protect your SMB: Encrypt sensitive data, apply security patches immediately, and restrict access to important files.
4. Royal Ransomware – The Sneaky One
Unlike other ransomware groups that use automated attacks, Royal ransomware operators are hands-on. They manually break into networks, spending time exploring systems before launching their attack, which makes them harder to detect. These attacks are often targeted at healthcare, education, and critical infrastructure, but SMBs are also at risk.
How it spreads: Social engineering, compromised credentials, and remote desktop attacks.
How to protect your SMB: Use endpoint detection and response (EDR) tools, monitor network activity for unusual behaviour, and limit remote access.
5. Phobos – The SMB Killer
Phobos is particularly dangerous for small and medium businesses (SMBs) because it relies on weak security, such as poorly protected remote desktop services. Unlike bigger ransomware gangs that go after corporations, Phobos targets businesses that are less likely to have strong cybersecurity in place.
How it spreads: Open RDP ports, weak passwords, and phishing.
How to protect your SMB: Disable RDP if it’s not needed, use a VPN for remote access, and implement network segmentation.
Final Thoughts: Don’t Be an Easy Target
Ransomware isn’t going anywhere. Attackers are constantly evolving their tactics, and SMBs that don’t keep up will get hit. The good news? A few basic security steps can massively reduce your risk:
✔️ Keep your software up to date (patch vulnerabilities ASAP).
✔️ Train your employees to spot phishing emails.
✔️ Use multi-factor authentication (MFA) on everything.
✔️ Back up your data regularly (and keep an offline copy).
✔️ Restrict access to critical files (not everyone needs admin rights).
