Summary
BM-Bank (formerly Otkritie FC Bank)
enterprise legacy
OPEN-FC-1-AS is a Russian banking network. The handle stands for Otkritie Financial Corporation ("otkritie" means open, and the abuse contact is still abuse@open.ru); Otkritie FC Bank was reorganised into JSC "BM-Bank" by accession at the start of 2025, and the RIPE registration follows the surviving entity.
What it's used for
Corporate infrastructure for a large Russian bank — internet-facing banking services, branch and office connectivity, and the network edge fronting its customer-facing systems. About 4,000 IPv4 addresses, small and purpose-built rather than a service-provider pool.
Notable
This is an end-user enterprise network, not a provider. Its upstreams are Russian incumbents — Rostelecom and VimpelCom — and the AS exists to multihome the bank's own address space rather than to sell connectivity to anyone else.
Interesting
The registry name lags the corporate reality by design: the OPEN-FC handle predates the merger, so a lookup shows the Otkritie-era identity attached to BM-Bank's org record. It is a good example of why an AS name should never be treated as the current legal holder.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
