There is no such thing as a secure server if it has an internet connection ...or old style modem.
Basic front line defense is a bat file that auto bans ips that try to connect too many times in a short time span.
Then ban ips that present certain known code snips ect...
I imagine FR has a log file with thousands of banned ips.
It used to be easy to “google” compromised code snips and get lists of sites running the code. It's harder now. But ....
My point is .... if enough of the wrong people with the right tools decided that some site or server was going down .. it would go down.
Ever notice that it is easier to tear something down ..than it is to build it up.
This could be a hoax ... hoping to cause a run .. or
It could be a group wanting credit out front ..
I'm not running out and emptying my bank account ... but I am keeping an eye out for odd traffic.
Good summary. Thanks
In addition, I can tell you as a Principal Infrastructure & Cloud Services Architect for a top ten global bank that there's always been a raging war between financial services and nation state hacking groups, independent hacking groups such as Anonymous/KillNet and REvil constantly probing and attacking our systems and services.
I maintain very close relationships with our Global Security Operations and Global Threat Management teams, both of which are fully focused on IT Security, Threat Management & Prevention and Remediation efforts. We take these threats seriously, constantly monitor social media for events like this, constantly get updates from the Feds (Intelligence, Regulators, etc..)
Attacks are expected to target the SWIFT payment system to paralyze payments between European & international banks, then attack from there (work outside in.)
After the attack earlier this week on US Government systems, this is being taken VERY seriously.
Anonymous, KillNet and REvil are trying to trigger a run on banks in the West, which would cause a collapse, their attack directly will not.
I hope you all enjoy your weekend, I will not because of the above.
