Summary

KCM SA

Bulgaria · AI-generated

business industrial bulgaria

KCM is operated by KCM SA, a non-ferrous metals smelter located in Plovdiv, Bulgaria.

What it's used for

  • The address space carries internal corporate traffic for the smelter, with netnames SPNET and KCM registered to A1 Bulgaria EAD Abuse and BTC IP ADDRESS SPACE administration respectively.
  • The AS announces 768 IPv4 addresses across 2 prefixes (92.247.110.0/23 and 213.91.176.0/24) and maintains a single observed neighbour, indicating a small, isolated corporate network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and industrial control systems for the non-ferrous metals production facility.

Notable

  • Registrants differ from the announcer; 92.247.110.0/23 is registered to A1 Bulgaria EAD Abuse while 213.91.176.0/24 is registered to BTC IP ADDRESS SPACE administration, suggesting leased or historically allocated space.
  • The inventory is small and finely subdivided into two distinct blocks, consistent with an internal corporate estate segmented by site or function.

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 1,783 prefixes, as published 2026-10-20. 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.
