Summary

CrediaBank

Greece · AI-generated

bank business corporate

ATTICA-BANK is the autonomous system for CrediaBank S.A., a major Greek commercial bank.

What it's used for

  • The space carries internal corporate infrastructure, evidenced by the netname GR-ATTICABANKSA-20060918 and registrant CREDIABANK S.A.
  • The inventory consists of a single IPv4 prefix, 89.31.176.0/21, totaling 2048 addresses, with 3 observed routing neighbours
  • This low neighbour count relative to the address block indicates a site-specific corporate estate rather than a transit or access network, supporting the bank's internal operations and branch connectivity

Notable

  • The registrant CREDIABANK S.A. aligns with the current operator, though the AS handle retains the legacy name ATTICA-BANK
  • CrediaBank was formed through the merger of Attica Bank and the former Pancreta Bank, which explains the retention of the original Attica Bank AS handle
  • The address inventory is a single contiguous /21 block, typical for a corporate network requiring a stable, manageable range for internal services

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 1,779 prefixes, as published 2026-10-24. 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.
