Why Phishing Attacks Spike In August

August 18, 2025

While you and your team may be returning from summer vacations, cybercriminals remain relentlessly active. Research from ProofPoint and Check Point reveals a notable surge in phishing attacks during the summer months. Here's how you can stay vigilant and safeguard your business.

Why Are Summer Months Riskier?

Hackers exploit the summer travel season by mimicking hotel and Airbnb websites, according to Check Point Research. They've identified a 55% rise in new travel-related website domains in May 2025 compared to last year, with over 39,000 domains registered—one in every 21 flagged as malicious or suspicious.

Additionally, the late summer back-to-school period triggers a spike in phishing emails impersonating legitimate university communications, targeting students and staff alike. Even if your industry isn't directly affected, employees checking personal emails on work devices can inadvertently expose your entire business network to cyber threats.

How to Protect Your Business

Although AI enhances cybersecurity and streamlines processes, it also enables more convincing phishing scams. That's why educating yourself and your team to recognize threats is crucial to avoid falling victim.

Follow these essential safety measures to defend against attacks:

• Vigilantly scrutinize suspicious emails. Don't just look for spelling errors or formatting issues; AI-generated emails can be flawless. Always verify the sender's email address and inspect links carefully to confirm their authenticity.

• Verify URLs thoroughly. Watch out for misspelled links or uncommon domain extensions like .today or .info, which are often used by scammers.

• Access websites directly. Instead of clicking links in emails or messages, manually type website addresses or use trusted bookmarks.

• Enable Multifactor Authentication (MFA). MFA adds an extra layer of security, ensuring your login credentials and sensitive data stay protected even if a breach occurs.

• Exercise caution on public WiFi. When using public networks, always connect through a VPN to secure sensitive transactions like bookings or banking.

• Avoid accessing personal emails on work devices. Mixing personal and business accounts on company hardware increases risk. Keep personal activities on personal devices.

• Consult your MSP about endpoint security. Endpoint Detection and Response (EDR) software monitors devices, blocks phishing attempts, and alerts your MSP immediately upon detecting threats, significantly reducing data exposure.

Phishing tactics evolve rapidly, accelerated by AI advancements. The best defense is a well-informed team prepared to identify and respond to these threats. Stay educated and protect your business.
