Incoming transactions guard for compromised accounts
Something else that I learned during the last leak is that, even if you warn the account owner of their leak and put their funds into their savings, that does not fully protects them yet. For instance, his account kept getting funds transferred into his wallet (I believe through automated trades) so these funds were at risk of being stolen since his private key was clearly displayed in the memo of a previous transaction of his.
I therefore had to log in again into his account and manually transfer his new liquid funds (1,600 HIVE) into his savings.
So, in order to avoid having to manually monitor compromised accounts, I decided to automate checks of funds coming into them.
The liquid funds of a compromised account will now be monitored every second, on BOTH platforms. This goes on until it detects that the owner changed their keys on both platforms (the transfer to savings transactions fails due to invalid key) or I manually interrupt the guard (eg. the owner notified me of the recovery of their account or other reasons).
ITG (Incoming Transactions Guards) for Compromised Accounts -> CHANGELOG:
Refactoring, additional logging, minor bug fix
Added the ability to run ITG as standalone process so that it can be executed independently from @keys-defender, when needed (eg. today I had to perform some maintenance on my server so I had to add a way to launch the ITG guard again).
Added a daily reminder transfer memo to notify the user that their account is still compromised and on which chain(s).
Time spent on these improvements : 4 hs (coding, testing, post)
