Over the last 30 days, detections of compromised IPs hosted in 🇮🇳 India have ⬆️ from 352,000 to 1.05 million (at the time of writing) – that's almost 3x! These are devices showing signs of malware infection, botnet control or abuse as residential proxies. This places India #1 for IPs linked to exploited devices, ahead of 🇧🇷 Brazil (808K) and the 🇺🇸 US (503K). Meanwhile, spam coming from Indian IPs is up 70% over the same period. 🌎 See all country rankings here: spamhaus.org/reputation-stat… Network operators in the region – are you seeing this in your abuse queues? #ThreatIntelligence #CyberSecurity #Botnets #India

We've observed a domain @FedEx promoted in a 2024 marketing campaign, "fedexbusinessinsights [.] com", redirecting to an Indonesian gambling site. Here's what we know 👇 (1/4)

The registration record shows almost nothing. It has the same creation date (2015), the same registrar and no sign it lapsed. There's just an "Updated Date" of 21 April 2026, with no clue what changed. We can't say how it happened. It could be domain warehousing by a registrar, or an agency that registered the domain under its own name. What we're confident about is that FedEx didn't knowingly send its brand to a gambling site.

The lesson for every brand: ✅ Treat every campaign domain as a permanent brand asset ✅ Make sure your organization is the registrant, not your agency ✅ Keep a list of all brand domains, with owners and expiry checks ✅ Keep monitoring domains even after you let them go Our DNS best practice guidance shows you how: 👉 spamhaus.org/resource-hub/dn… (4/4)
