Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
On Spamhaus ASN-DROP Spamhaus lists this entire
network (associated domain sinoworldwidetrading.com)
as controlled by, or hijacked for, cybercrime. Many operators null-route
everything it originates.
2 DROP matches Announced space overlapping the DROP prefix list.
| Announced | DROP entry | Record |
|---|---|---|
| 87.120.104.0/24 | 87.120.104.0/24 | SBL699922 |
| 91.92.41.0/24 | 91.92.41.0/24 | SBL701005 |
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,843 prefixes, as published 2026-11-01. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
85.11.187.8 | FortiBleed Operations Continue Targeting Exposed Systems Leading to Reports of Lockouts | 2026-10-06 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
