Asia Crypto Scams Combine Malvertising and Pig Butchering: ¥10M Losses

Sophisticated crypto scams target Asia, especially Japan, blending malvertising with pig butchering tactics. Victims lose up to ¥10 million through fake social media ads leading to AI-powered chat scams. Infoblox identified over 23,000 suspicious domains driving the campaign.

Attackers place convincing ads on Facebook and Instagram impersonating financial experts. Ads promote “AI-driven” investment algorithms with guaranteed returns. Victims click through to fake investment portals with QR codes for LINE, WhatsApp, or KakaoTalk groups.

AI chatbots engage victims 24/7 across multiple languages. Bots share fake success stories and encourage small test deposits. Early “profits” build trust for larger transfers. Withdrawal attempts trigger “release fee” demands before scammers disappear.

Attack Chain Breakdown

Five-stage operation scales through automation.

1. Malvertising: Social media ads impersonate experts
2. Lure sites: Fake portals with QR code entry points
3. Chat onboarding: LINE/WhatsApp/KakaoTalk group access
4. Trust building: AI bots deliver fabricated returns
5. Cash out: Release fee scam extracts final payments
