Every October, inboxes and social feeds light up with haunted discounts, candy giveaways, and spooky deals. But behind the pumpkins and promise of free treats, cybercriminals are hard at work.
Halloween-themed scams aren’t confined to a single channel or audience. Bitdefender Labs’ research shows that cybercriminals blend multiple fraud tactics into one seasonal wave, casting a wide net that targets nearly every type of internet user.
In this year’s campaigns, scammers didn’t stick to one formula. They mixed fake retail sales, cryptocurrency bonuses, brand giveaways, and even dating lures — all wrapped in Halloween imagery designed to catch attention.
Between September 15 and October 15, 2025, Bitdefender Labs researchers detected a global surge in Halloween-themed phishing and scam campaigns — from inbox-baiting emails to sponsored social media ads distributing malware.
Here’s what they found.
Bitdefender Antispam Lab flagged emails designed to mimic brands like Walmart, Amazon, and Home Depot, promising free candy boxes, skeleton decorations, or costumes.
At first glance, they look legitimate, but these messages lead straight to phishing pages and scam websites. According to Bitdefender telemetry:
Our data shows that the United States received 73% of all Halloween-themed spam, followed by Germany (13%) and Ireland (6%). Smaller volumes reached the UK, Romania, Australia, Italy, Canada, and France.
On the sending side, 67% of all Halloween spam originated from servers in the United States with Germany, Singapore, Latvia, and the Netherlands trailing behind.
These attention-grabbing subject lines use the promise of free items, limited-time offers, or exclusive gifts to entice recipients to open emails and click on malicious links. Many impersonate well-known brands to gain credibility and exploit seasonal excitement.
Bitdefender researchers also spotted a regional campaign in Japan promoting a fake “Halloween Jumbo Lottery.”
The email claimed users could receive 22 free lottery tickets worth 6,600 yen just by registering or logging into the “official lottery website.” The instructions appeared legitimate and even mimicked a real campaign’s tone and format.
The Meta Connection: Fake Ads and Malware Disguised as Halloween Treats
Bitdefender Labs also uncovered a network of malicious Halloween ads running on Meta platforms (Facebook and Instagram), where scammers purchased sponsored placements to promote fraudulent offers and even Malware.
Fake sponsored ads promised crypto users two “Halloween gifts”:
When users clicked, they were redirected to fake download domains such as desktopappdownload.com — sites distributing multi-stage malware disguised as legitimate trading tools.
Bitdefender Labs has been tracking this malware since April 2025, following an extensive malvertising campaign that used mass brand impersonation of trusted cryptocurrency exchanges and trading platforms such as Binance and TradingView.
The infection chain is highly sophisticated, operating in several stages as previously explained in here. The additional payloads silently dropped after the victim downloads the trojanized app are designed to steal browser cookies, authentication tokens, and cryptocurrency wallet data. The malware also connects to a command-and-control (C2) server allowing it to receive updates or new modules, that enable data exfiltration and persistent access. The malware also features sandbox detection, evasion mechanisms, and frequent code updates, showing active development and global reach.
Meta transparency data revealed the campaign targeted European users (Bulgaria, Croatia, Romania, Slovakia, Slovenia) aged 18–65+, confirming its regional precision and broad age targeting.
Even when Meta flagged and removed some ads for “not meeting transparency requirements,” duplicates reappeared under new accounts hours later.
Other Halloween-themed scam ads used fashion brands to lure consumers with “up to 80% off” deals.
Both domains used stolen product photos and other brand imagery.
Holiday periods are prime time for cybercriminals because:
Whether it’s a fake giveaway, a “Windows-only” crypto offer, or a too-good-to-be-true discount, the goal is the same: harvest data, install malware, and profit before detection.
From fake candy boxes to phony crypto gifts, Halloween 2025 proves that scammers are as creative as ever. Their lures may adapt to the season, but their motives never change: to trick users into giving away data, money, or hand over access to devices. So, when it comes to online safety, the scariest threats this Halloween aren’t supernatural — they’re socially engineered.
