Discriminating malcious packets using TTL in the IP header
Ryo Yamada, Kazuhiro Tobe, Shigeki Goto (Waseda University) IN2011-176
Abstract (in Japanese) (See Japanese page) 
(in English) It is known that an IP packet passes through less than 30 routers before it reaches the destination host. According to our observation, there are strange IP packets whose Time-To-Live (TTL) values are decreased more than 30 from the initial TTL. These packets are likely to be generated by a special software. We assume that IP packets with strange TTLs are malicious. This paper investigate this conjecture through several experiments. As a result, we show that it is possible to discriminate malicious packets from legitimate ones only by observing TTL values.
Keyword (in Japanese) (See Japanese page) 
(in English) TTL / hop count / malicious traffic / network security / / / /
