“Use once” spear phishing “mail.portalinbox-read.host”


An interesting one this morning. Phishing is nothing unusual but this one was.

For a start the sender of the junk blamed the victim and said that the victim has a virus (not true, no email traffic exited the company’s system towards the sender until after the initial phishing had come through from the sender).

Secondly the link can only be used once not too uncommon.

Third!!!! The phishing url had the logo of the victim company! Very unusual.

This screams “spear phishing” where a specific company or person is targeted.

Sorry about the amount of redaction in this but I can’t publish the identifiers:


“Use once” spear phishing “mail.portalinbox-read.host”

Frustratingly each link is “use once”.. I “burned” the first link while not recording the traffic :(. No worry other people within the organisation also got the same message.

This time I recorded it!

Interestingly one of the components is an API and json file containing details about the victim!

hxxps://mail.portalinbox-read.host/api/7d4a3a863190b274db04730c?Lodmafs=&o3nS5Not=_P33a-badaF&Lodmafs=

(Identifiers modified to obscure the victim details.)

Which responds with this amazing set of details about the victim:

{ "_id": "johnsglazing.com", "createdAt": "2018-10-14T11:11:21.374Z", "favicon": "/f8a47589292fab3b3a7857bd1dd87547/favicon.ico", "images": [{ "url": "https://REDACTED.png", "mime": "image/png" }, { "url": "http://REDACTED-logo.jpg", "mime": "image/jpeg" }], "ispname": "Glazing", "logo": "9b784a7e72b1ba74837cc73a7a31aa09.png", "updatedAt": "2018-10-14T11:11:21.323Z", "email": "john.ethridge@johnsglazing.com", "p": "https://trk.news3.icu/geo-go" }

Someone has put a lot of research into making a database of companies, contacts and their logos. Also seems to show the date that the data was compiled.

The phishing page then also steals information about the victim and their computer system.

There is a hefty javascript file that seems to run the entire thing:

Host I saw: “mail.portalinbox-read.host” IP: 40.76.86.98 (seems to be an azure instance).

Quite the operation!
