Unfortunately, our "network" is only two people in a small and secured office. The rest of our users are customers.
Also, locally we are not using any Windows computers. It is all Linux and Mac. Not to say that there are not keyloggers for macs or CentOS; however, less likely being (i) only two of us, (ii) secured office, (iii) no windows.
This has also happened to two Zimbra accounts now as well. The two accounts too which it has happened are not related accounts, different companies who do not know each other. |
