The domain nwolb.com is owned by Natwest Bank, it was first registered in 1999.
It is used when you click to login to online banking.
Personally, as someone who is not a Natwest customer the domain nwolb.com looks fake to me and I had to double check it was genuine when writing this post. You Google Natwest and you get natwest.com then when you go to login you get directed to this.
If you lookup this domain name on WhoIs tools online you will notice that this does not show as been owned by Natwest but comes back as CSC Corporate Domains, Inc. This can cause a lot of people to think the domain is not genuine.
We have reported in the past (details here) about spam e-mails that appear to come from this domain, but the e-mails are actually fake and use spoofed addresses.
As you can see from the below image when on natwest.com there is a link to “Log in to Online Banking” and it is this link that takes you to nwolb.com
