Why Phishing Attacks Spike in August

August is peak phishing season for a reason. Here is exactly why attackers time campaigns this way, and how to protect your team.
Every August, security teams across Minneapolis-St. Paul see a predictable spike in phishing attempts - and it isn't a coincidence. Attackers time their campaigns around exactly the moments when your team's guard is down.
Why August Is Prime Phishing Season
Late summer combines several factors that work in an attacker's favor: vacation schedules leave key staff and their backups distracted, back-to-school season creates a flood of legitimate-looking retail and shipping emails to hide malicious ones inside, and Q3 budget and planning activity increases financial email traffic that phishing emails can mimic convincingly.
What August Phishing Campaigns Look Like
- •Fake shipping and delivery notifications timed to back-to-school shopping volume.
- •"Urgent" wire transfer requests impersonating executives who are known to be traveling or on vacation.
- •Fake IT or HR emails about "mandatory system updates" sent when help desks are short-staffed.
- •Invoice and payment fraud targeting finance teams during a period when normal approval chains are disrupted by time off.
Why Financial Services, Construction, and Manufacturing Firms Are Frequent Targets
Financial services firms handle wire transfers and client funds attackers want directly. Commercial construction companies process large subcontractor and vendor payments that are easy to redirect with a convincing fake invoice. Manufacturers often have smaller IT security teams relative to their revenue, making them attractive, lower-resistance targets.
How to Protect Your Business During Peak Phishing Months
- Confirm backup approval chains are active before anyone leaves for vacation - never let one person be the sole approver for wire transfers.
- Run refresher phishing simulations in July, before the August spike hits.
- Require verbal confirmation for any payment or banking detail change request, no exceptions.
- Make sure email filtering and DNS-based protections (SPF, DKIM, DMARC) are properly configured, not just "turned on."
