I am sharing some malicious IP addresses for the community that I found continuously attacking Bangladesh financial sectors. I will be updating the list as my research going on always. New IP address will be placed below most serially, with a new tag mark. That will help you to understand what are the previous ones and what are the new ones.

Explanation of why they are malicious?

I have observed that these IP address continuously attacking (brute force, directory traversal, port scan, calling web shell etc.) one of the financial infra. During analyzing phase, I collected this IP and check their reputation in some renowned TI service like abuseipdb db, cisco talos, IBM x-force etc. and found that very bad reputation. Sometimes I found IP addresses and they are completely clean as per the TI but during analyzing the payload/url it seems abnormal i.e. trying to read /etc/passwd file. I also mention those IP address here in the list.

You just need to block this IP addresses on your perimeter security devices like in your firewall or IPS or EDR/server security solutions.
