Summary
Kyobo Securities
enterprise legacy
AS9577 (KYOBOTRADE-AS) is held by Kyobo Securities Co., Ltd., a Seoul-based brokerage and investment bank offering securities and derivatives trading, underwriting, corporate finance, asset management and wealth management. It is a financial-sector enterprise AS, run for the firm's own trading and client-facing systems rather than sold as a service.
What it's used for
RIS observes 3 IPv4 prefixes totalling 768 addresses (203.239.34.0/24, 211.234.59.0/24, 220.78.134.0/24), no IPv6, and 4 BGP neighbours. Three unrelated /24s taken from three different ranges, multi-homed to four peers, is the standard build for a securities firm: the addresses are the stable, allow-listed endpoints for retail trading platforms, HTS and mobile trading apps, market-data feeds and links into exchange and clearing infrastructure, and the multiple upstreams exist because a routing outage during market hours is a business incident, not an inconvenience. Four neighbours on 768 addresses is a redundancy ratio you only see when uptime matters far more than volume.
Notable
- Reverse DNS on the sampled addresses in
203.239.34.0/24returns genericcustomer.epnetworks.co.krrecords. Those are a Korean provider's default PTRs for customer space, so they say where some of the network is homed, not who holds it. The AS itself remains registered to Kyobo. - Kyobo Securities is listed on the Korea Exchange (ticker 030610) and sits within the wider Kyobo group.
- As with most brokerages, the public address footprint is only the exposed edge; the trading and settlement estate behind it is private and never appears in BGP.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 445 networks and 1,817 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
