In 2025, email is still the #1 communication channel for business—and the #1 attack vector for cybercriminals.

Despite better tools and smarter users, email-based threats continue to evolve with AI-powered scams, deepfake phishing, and sophisticated impersonation tactics.

If your business email isn’t protected, you could be one message away from a serious data breach or financial loss.

Here are the top 5 email threats to watch out for in 2025—and how to stop them with PLiKhost’s advanced email security, powered by SpamExperts.

⚠️ 1. Business Email Compromise (BEC)

What it is:
Attackers impersonate a company executive or vendor to trick employees into transferring money or sensitive data.

How it works:

• “CEO” asks finance team for urgent wire transfer

• “Vendor” changes banking info in an invoice

• “Client” requests files containing private info

🛡 How to stop it:

• Enable outgoing email filtering to prevent domain spoofing

• Use SPF, DKIM, and DMARC records properly

• Train staff to verify unusual requests

SpamExperts scans for sender anomalies and blocks spoofed emails at the server level.

🐟 2. Phishing & Spear Phishing

What it is:
Fake emails that mimic real brands (banks, SaaS platforms, etc.) asking users to log in or update their info.

How it works:

• Links lead to fake login pages

• Victims enter real credentials

• Attackers take over accounts

🛡 How to stop it:

• Use SpamExperts Incoming Filtering to block known phishing patterns

• Train users to spot suspicious links

• Enable 2FA (two-factor authentication) for email logins

With a 99.98% detection rate, SpamExperts stops phishing before it ever hits the inbox.

🧪 3. Malware Attachments & Ransomware

What it is:
Malicious files (PDFs, ZIPs, .docm, .exe) sent via email that, once opened, infect the system.

What it does:

• Encrypts files and demands ransom

• Installs keyloggers or backdoors

• Spreads through internal networks

🛡 How to stop it:

• Use real-time antivirus scanning in your email filters

• Block certain file types via policy

• Store regular email and file backups (PLiKhost offers local & remote backups)

SpamExperts scans all attachments for viruses and quarantines dangerous messages automatically.

👤 4. Spoofed Senders & Fake Domains

What it is:
Emails that appear to come from your own domain or a known brand, but are actually forged.

Why it’s dangerous:

• Damages your company’s reputation

• Causes confusion or data leaks

• Can bypass filters if not configured properly

🛡 How to stop it:

• Enforce SPF/DKIM/DMARC records

• Monitor outgoing traffic for abuse

• Use SpamExperts’ sender reputation filtering

PLiKhost helps configure authentication records and actively monitors for spoofing attacks.

📥 5. Inbox Overload & Productivity Drain

What it is:
Floods of marketing spam, irrelevant newsletters, and graymail that bury important business messages.

Why it’s risky:

• Users miss real emails

• Increased chance of accidental click on harmful content

• Wasted time sorting through inbox

🛡 How to stop it:

• Use intelligent spam classification (not just keyword filtering)

• Let users manage their own quarantines

• Archive clean mail and reduce clutter

SpamExperts filters low-priority email into a quarantine interface so your inbox stays focused.
