Hack of Polish Financial Supervision Authority and Polish banks

Hack of Polish Financial Supervision Authority and Polish banks

A couple of days back the financial sector in Poland was shocked by the news that the Polish financial supervision authority was hacked and was used as an attack vector to get access to other (mostly Polish) banks.

This is a very short summary with some IOCs (Indicator of Compromise) that you can use to check your logs and verify if you are affected.

Note that most of this information is composed from information found at

All credit goes to the authors of those posts. I merely merged the info from both posts (and you no longer had to go through Google Translate to read the Polish post).

Note that you can also get the IOCs in an easy accessible format via the OSINT feed of botvrij.eu. If you have a local MISP instance you can subscribe to the botvrij.eu OSINT feed (at no cost). Feel free to contact me if you need help setting up MISP and integrate it in your incident management workflow. Also see MISP EcoSystem – Threat Intelligence, VMRay, MISP. The UUID for this event is 58998603-c66c-49a0-a485-1689c0a8ab16.

Preparation, Delivery, Exploitation and Actions on Objective

  • So far there is no evidence that funds of customers of any bank are (or were) at risk
  • The attackers (ab)used the trust banks -and their employees- put in the supervision authority
  • Protection rules set forward for the banks were not fully applied by the regulator
  • The server side attack was made possible because of a not patched vulnerability in JBOSS (stored XSS) and inserted malicious javascript code, this code was then sent to the clients visiting the website
  • It’s uncertain if for example CSP would have prevented this attack : “but considering the attack vector and the careful preparation of the attack they would have to be able to work around – modifying, removing CSP or load malicious code from the KNF website”
  • There was a similar event (but no claims that it is related to this attack) against the ComisiĆ³n Nacional Bancaria y de Valores, Mexican financial authority
  • The infection of the visitors only took place if the source IP was in the target list (see Target list subnet below)
  • Remarkably, the same malicious software was also found at victims that were not in the target list
  • The attack exploited vulnerabilities in browser plugins Silverlight and Flash
  • Once the malware was injected, it downloaded its final payload from other servers
  • Was there a link with other attacks? (info from Polish post) Apparently, the software used is very similar to that used in the SWIFT attack in 2016. A word of warning though. Malware is often developed with the use of libraries. These libraries are shared and reused. Seeing the same characteristics in malware does not mean that it is the same group that conducted he attack. Also, the goal of the so-called SWIFT attackers was financial theft, with the current available information this was not the case for this attack.
  • So what was the goal of the attackers?
    • There was no financial gain as no funds were stolen
    • Was it theft of financial or personal data?
    • Financial data (transactions, history) can also be very (more?) valuable

    first of all, thanks for your information regarding to Polish banks security issue.

    I have a question about above IPs list marked as infected. how do you know that these IPs are infected ? are theses IPs extracted from C2 ?

    if these IPs are extracted from KNF web log, I think all of IPs can not be infected by exploit toolkit if the devices connected to KNF are patched for silver light or flash.

    i just wonder about it
