Wells Fargo Squatting Campaign – IBM X-Force Early Warning

Summary

X-Force has identified a new squatting campaign used by threat actors to target the finance and insurance sector. The campaign has a global scope assumingly luring users into giving away their login credentials.

Threat Type

Squatting Domain, Phishing Domain, Credential Theft

Overview

We observed 3 Squatting Domain registrations related to a victim in the finance and insurance sector. The campaign was identified starting with the registration on 2020-03-07 01:15:57 up to the latest registration on 2020-03-12 11:13:30.

For all registered domains we could identify NameCheap, Inc. as the registrar based in Panama. The email address used for registering the domains was anonymized.

The registered domains could not be resolved to any hosting IPs throughout our analysis.

However the registrar NameCheap, Inc. covers a pool of 38.312.478 domains where at least 0.43% can be considered as potentially malicious.

The following list shows the nameserver that are configured as authoritative nameservers for the domain and their malicious score which is the percentage of malicious domains with the same nameserver.

Domain: mobil-support-wells-fargo.work
Name server: dns1.registrar-servers.com
Name server malicious score: 0.98%

Domain: mobil-support-wells-fargo.work
Name server: dns2.registrar-servers.com
Name server malicious score: 0.98%

Domain: support-team-wells-fargo.work
Name server: dns1.registrar-servers.com
Name server malicious score: 0.98%

Name server malicious score: 0.98%

Domain: support-wells-fargo-team.work
Name server: dns2.registrar-servers.com
Name server malicious score: 0.98%

Not forgetting to mention the WhoIs Server: X-Force was able to retrieve the WhoIs server information where we were also able to determine the number of domains each WhoIs server manages and as well adding the malicious rating of the domains in the pool.

Domain: mobil-support-wells-fargo.work
Whois server: whois.namecheap.com
Whois server malicious score: 0.44%

Domain: support-team-wells-fargo.work
Whois server: whois.namecheap.com
Whois server malicious score: 0.44%

Domain: support-wells-fargo-team.work
