Now people might think that how did they do it? The attackers simply intrude with the target’s Outlook mailbox by formulating new commands that will easily redirect important email to a separate folder, just like the RSS Feeds folder, as it’s not used by the individual generally.
Not only this, but the hackers also register separate similar domains that mimic the legitimate domains of the entities involved in the email correspondences that they want to intercept, which allow them to perpetrate a MITM attack by sending emails from the fraud domains on behalf of both the parties.
During the investigation of this above operation, which is conducted by the Florentine Banker group, the security company, Check Point’s Incident Response Team (CPIRT) have collected forensics data and observed the use of different domains that were carried in this operation.
In the investigation, the security researchers found that seven different domains were utilized by the attackers, which are similar lookalike domains, or a website to serve the Phishing pages.
They stated that they managed to collect all the information from several WHOIS portals. They got unique knowledge with the help of WHOIS portals, as the information they found on several WHOIS portals simply influenced them to find extra 39 similar domains that are registered throughout 2018-2020.

- Fake bank accounts were also settled in Hong Kong and the United Kingdom.
- Various email strings in Hebrew combined relevant leads that were not utilized by the attacker, and this simply leads the security researchers to understand that they do not talk in Hebrew.
