Why Hackers Attack During the Holidays (and How to Be Ready)

Hackers don’t take holidays off — they schedule around yours. Attacks reliably spike on long weekends and holiday weeks, when staffing is thin, responses are slow and everyone’s guard is down. Here’s why the next few weeks are prime hunting season, and how to get ready without canceling anyone’s vacation.

Why attackers love the holidays

The pattern is well documented. The FBI and CISA have formally warned that ransomware groups favor holidays and weekends — a warning issued back in 2021 after Colonial Pipeline was hit going into Mother’s Day weekend, meat producer JBS over Memorial Day, and the Kaseya attack landed on the Fourth of July weekend.

The logic is simple. Ransomware needs quiet hours to spread and encrypt before anyone reacts, and a half-staffed company can turn a fifteen-minute response into a three-day head start. Add year-end pressure in finance departments — closing the books, paying final invoices, hitting deadlines — and holiday weeks are simply when attacks work best.

Small businesses feel this more, not less. A large enterprise runs a 24/7 security operations center whether or not it’s Christmas Eve; a 30-person firm often has one IT person, and that person is carving a turkey. Attackers know the difference, and their scanning tools don’t narrow the target list by company size.

The break-in happens before the break

Here’s what most businesses miss: attackers who strike on December 24 usually got in around Thanksgiving. They spend weeks inside quietly — mapping the network, collecting passwords, locating backups — then pick the emptiest day on the calendar to pull the trigger.

That means December is the month to hunt for early signs: new administrator accounts nobody remembers creating, VPN logins at strange hours, security tools or backup jobs mysteriously disabled. Catching those now is the difference between an incident report and a ransom note.

A practical way in: have whoever manages your systems pull three simple reports this week — accounts created in the last 60 days, remote logins outside business hours, and any change to backup schedules. Thirty minutes of reading, and it covers the most common pre-attack fingerprints we see.

Holiday scams to warn your team about this week

  • Fake delivery notices. Everyone is expecting packages, so “your shipment is delayed, click here” lands far better in December.
  • Gift-card requests from the boss. The classic “are you free? I need gift cards for clients, keep it quiet” text.
  • Year-end banking changes. A vendor emailing new payment details right before the close deserves a phone call to a number you already have — every time.
  • E-cards and party invites carrying credential-harvesting links.
  • Over-detailed out-of-office replies that tell attackers exactly who is away and until when. Keep them vague on names and dates where you can.

Your holiday readiness checklist

  1. Write down who is on call each day of the break, with real phone numbers, and make sure everyone knows the escalation path.
  2. Run a patch-and-MFA sweep before the office empties, especially on VPNs and anything internet-facing.
  3. Test an actual restore from backup. “The backup job ran” is not the same as “we can recover.”
  4. Freeze risky changes — new firewall rules, big migrations — until January.
  5. Require phone verification for any payment or banking change during the break, no exceptions.
  6. Confirm someone is genuinely watching your network overnight and on the holidays themselves.

That last item is where small businesses most often fail quietly: alerts fire at 2 a.m. on December 25 and nobody sees them until January 2. Our clients have real engineers watching around the clock — a big part of why, across every ransomware case we’ve handled, we have recovered our clients’ data 100 percent of the time.

Key takeaways

  • Ransomware groups deliberately strike holidays and weekends, and federal agencies have warned about it since 2021.
  • The intrusion usually happens weeks before the attack — hunt for quiet warning signs now.
  • Seasonal phishing rides delivery notices, gift cards and year-end payment changes.
  • An on-call list, a tested restore and phone-verified payments cover most of the risk.
  • If nobody watches the network over the break, every other control reacts too slowly.
