American Express Account Alert: Personal Safe Key (PSK) – Phishing


We are seeing a mass run of phishing emails spoofing American Express saying Please create your Personal Security Key. There are 3 sites so far discovered that attempt to perform this phishing attack



Currently all 3 sites fail to resolve from a UK IP address. They were all registered yesterday 8 March 2021 via using Chinese details which I assume are false. The name servers associated with the domains are DNS1.NEWSITEDNS2.RU and DNS2.NEWSITEDNS2.RU

Edit: after a bit of digging around, it appears that the NEWSITEDNS2.RU has previously been used for Amex and other bank phishing attacks. It is suggested that you block their IP numbers to prevent further and future problems

  • VirusTotal
  • VirusTotal
  • VirusTotal


Either the DNS has not propagated yet worldwide or the DNS service has pulled the domains. My gut feeling is that the bots have sent the emails too early before the sites were live. The date & time on the emails say Wed 30/09/2021 13:32 . I received about 50 copies of these between 03.20 and 03.30 UTC.

Be aware and watch out for when these do go live, probably later today
