Bizzare network attack?

I hope it's not too late, but let me rephrase and try to think (though it's hard when Dream Theater are injecting stereo sounds directly into the brain 
)
The user downloaded the file, and it was corrupted - the user is on a totally different than your location, right ? Then, you downloaded it, and it was bad again. Then, the file, on the server, was OK ? To me, it sounds that someone with access has changed the file while it was on the server and you should rather dig into the server's access logs. While it's possible that someone will spoof you via those insecure Wi-fi networks and protocols, do you really suspect someone in your area messing with files ? If it's the infamous cialis - have you check the anti-virus status of the systems ? My $0.2.

In my logs I find entries about attacks on my system. I know IP addresses, I know date and time and I know what they tried to do. So what's the best I can do now? Tell everybody that there are cybercriminals on that network? Write an email to their admin? Anything else? (10 Replies)

ip-token - tokenized interface identifier support SYNOPSIS
ip token { COMMAND | help } ip token set TOKEN dev DEV ip token del dev DEV ip token get [ dev DEV ] ip token [ list ] DESCRIPTION
IPv6 tokenized interface identifier support is used for assigning well-known host-part addresses to nodes whilst still obtaining a global network prefix from Router advertisements. The primary target for tokenized identifiers are server platforms where addresses are usually manually configured, rather than using DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still determine their network prefix by use of SLAAC, but more readily be automatically renumbered should their network prefix change [1]. Tokenized IPv6 Identifiers are described in the draft [1]: <draft-chown-6man-tokenised-ipv6-identifiers-02>. ip token set - set an interface token set the interface token to the kernel. TOKEN the interface identifier token address. dev DEV the networking interface. ip token del - delete an interface token delete the interface token from the kernel. dev DEV the networking interface. ip token get - get the interface token from the kernel show a tokenized interface identifier of a particular networking device. Arguments: coincide with the arguments of ip token set but the TOKEN must be left out. ip token list - list all interface tokens list all tokenized interface identifiers for the networking interfaces from the kernel.
