Introduction
We want to provide the best, most innovative, and most accurate threat intelligence in Abusix Mail Intelligence possible.
We believe strongly in the "Release Early, Release Often" methodology and allow our customers "early access" to what we are working on so that if they choose, they can also test and provide us feedback on that work.
We provide access to "beta" lists as separate DNS zones and within rsync. For rsync customers, access is granted in the "beta-lists" module, enabled in the getabusix.conf file.
Zones
btc-wallets (Bit Coin Wallets)
Status:
Beta
Type:
SHA-1 hash
Cloud DNS namespace:
<APIKEY>.btc-wallets.mail-beta.abusix.zone.
Rsync File:
beta-lists/btc-wallets.zone
Return Codes:
127.0.4.1
Test Points:
127.0.0.2
Listing Duration:
Approximately 5.2 days after last seen
Description
We developed this zone to list BTC Wallet addresses seen in the message body of spam sent to traps.
Because it is impossible to represent a BTC Wallet address in a DNS query, they are SHA-1 hashed, and the hash value is used for lookup instead of the URL.
For example:
SHA-1(15GWKdT8e1o6GcDTZMQZRiZng2Q6dLX8Aw) ->
e108c5b4bde457dcc35f009d05a21fa383eda04cattachhash (Attachments)
Status:
Beta
Type:
SHA-1 hash
Cloud DNS namespace:
<APIKEY>.attachhash.mail-beta.abusix.zone.
Rsync File:
beta-lists/attachhash.zone
Return Codes:
127.0.5.1
Test Points:
127.0.0.2, 127.0.5.1, 3395856ce81f2b7382dee72602f798b642f14140 (EICAR with trailing newline), cf8bd9dfddff007f75adf4c2be48005cea317c62 (EICAR)
Listing Duration:
Approximately 5.2 days after last seen
Description
This experimental zone lists the SHA-1 hashes of any attachments seen by our trap network.
forged
Status:
Beta
Type:
IPv4, IPv6
Cloud DNS namespace:
N/A, not currently published
Rsync File:
beta-lists/forged.zone
Return Codes:
127.0.0.5
Test Points:
127.0.0.2, 127.0.0.5
Listing Duration:
Approximately 5.2 days after last seen
Description
This zone lists IP addresses we have observed either forging mail from our trap domains or where we see traffic from IP addresses sending mail from domains that return SPF Fail results.
backscatter
Status:
Beta
Type:
IPv4, IPv6
Cloud DNS namespace:
N/A, not currently published
Rsync File:
beta-lists/backscatter.zone
Return Codes:
127.0.0.6
Test Points:
127.0.0.2, 127.0.0.6, ::FFFF:7F00:2, ::FFFF:7F00:6
Listing Duration:
Approximately 5.2 days after last seen
Description
This zone lists IP addresses that have sent bounce messages to our traps. Our trap domains are never used to send an email, so any bounce messages we receive are because someone else forged our domain, so any host sending us bounce messages is because they incorrectly accepted one of these messages and are therefore sending us "backscatter.”
Backscatter can be a big problem if a domain is forged and used for a large spam run, and this zone can help mitigate the fallout from this.
Unlike other blacklists, our only inclusion criteria are DSN/MDN messages; we do not consider "Sender Verification" or "Sender Callouts" as backscatter.
emailbl
Status:
Beta
Type:
SHA-1 hash
Cloud DNS namespace:
<APIKEY>.emailbl.mail-beta.abusix.zone
Rsync File:
beta-lists/emailbl.zone
