This vulnerability allowed attackers to send a HTTP request with
malicious code tucked in the content-type header
This allowed strut 2 to be tricked into running the code and lead to
opening the sytem it was running
March 8, 2017: The united states computer emergency readiness Team
(US-CERT) warned about the apache software's struts 2 vulnerability
This warning was given for companies to addres it

March 9, 2017: Equifax administrators were told to apply
patch but it wasn't done
March 10, 2017: Hackers were searching for servers that
contained this vulnerability and found Equifax's dispute portal

May 13, 2017: Hackers began moving from these servers into
other parts of the network and taking data
With the credentials, they were able to access 48 more

Until july 29, 2017: Hackers stole data
They stole the data by encrypting the data while moving it so they
would not be noticed
Equifax had tools that were used to decrypt analyze, and re-encrypt
network traffic using a public-key certificate
Equifax had failed to renew their certificate; the traffic wasn't getting
inspected
Only when they renewed it on this july 29, it is when they noticed
Septemberr 8, 2018: after internal investigation, the public was let know
of the breach
After the breach, no identity theft occurred as it is believed to be chinese
state-sponsoredhack
