The attached file contains 36 months data sorted in descending order by number of attempts and originating ip address.
Is it possible to block any type of communication with an ip address after so many (5 or 10) failed attempts. The documentation(for Openssh) says that it is possible to slow the login rate after so many (default 10) failed passwords, but that only seems to apply if the perpetrator logs in once and repeatedly enters passwords. If each attempt is only the first attempt then this rule does not apply.
Hi,
Could anyone direct me to any sites that have any info on unix attcks or hacks in the last 5 years. This is needed for an assignment. All help would be greatly appreciated.
Thanks:) (6 Replies)
I've recently registered for the site and have found it very useful thus far. However, I am a student currently researching network attacks, specifically, denial of services and the damage posed to operating systems. If you have any information about this topic, please send to me.

It's an online con that is growing fast and stealing tens of millions of dollars.
An e-mail seemingly from a financial institution instructs you to log on to a legitimate-looking Web site. Such “phishing” attacks exploit a universal weakness in online security: passwords.

traceends
TRACEENDS(1) User Commands TRACEENDS(1)NAME
traceends - summarise traffic done by every endpoint observed in a trace
SYNOPSIS
tracetopends [ -f bpf | --filter=bpf] [ -a addrtype | --address=addrtype] [ -H | --help]
inputuri [inputuri ...]
DESCRIPTION
traceends reports the number of bytes and packets sent and received by each endpoint observed in the input trace(s). Usually, you don't
want to run this program directly -- see tracetopends instead.
-f bpf filter
output only packets that match tcpdump style bpf filter
-A address type
Specifies how an endpoint should be defined. Suitable options are "mac", "v4" and "v6" which will report endpoint stats for each
observed MAC address, IPv4 address and IPv6 address respectively.
OUTPUT
Output is written to stdout in columns separated by blank space.
The columns are (in order):
* Endpoint address
* Time last observed
* Packets originating from the endpoint
* Bytes originating from the endpoint (IP header onwards)
* Payload originating from the endpoint (post transport header)
* Packets sent to the endpoint
* Bytes sent to the endpoint (IP header onwards)
* Payload sent to the endpoint (post transport header)
EXAMPLES
Get stats for each individual MAC address in a trace:
traceends -a mac erf:trace.erf.gz
