NOTES:

- A Threat actor leveraging the same domain pattern has registered over 10k domains for various SMS phishing (smishing) scams.
- The root domain names all begin with the string: com-
- Since the root domain begins with "com-" next to a subdomain, the full domain might trick potential victims doing a casual inspection.
- The domain names indicate pages impersonate toll services and package delivery services in at least 10 US states and one Canadian province.
  -- US states: California, Florida, Illinois, Kansas, Massachusetts, Pennsylvania, New Jersey, New York, Texas, Virginia
  -- Canada province: Ontario
- The smishing entices users to reveal personal and/or financial information, including credit or debit card and account information.
- These smishing text messages originate from email addresses or phone numbers.
- Apple iMessage does not allow links in messages received from unknown senders.
  -- To bypass this, these smishing texts ask users to reply with "Y" and reopen the text.
  -- Such interaction from the user allows iMessage to enable links in the smishing texts.

- Over 70% of these domains use the same two name servers and resolve to IP addresses from popular hosting providers.
  -— 93% of the resolved IP addresses belong to AS13335 (Cloudflare).
- We will continue to track and block this campaign, which we have named: com_smishing
