ABSTRACT:
The nature of consecutively detecting outgoing messages gives rise to the consecutive
recognition problem. Spam messages refer to the discovery of the compromised machines used
for directing junk messages and spamming provides a serious financial motivation intended for
the controllers of the compromised machines on the way to novice these machines which are
involved in spamming. A tool is developed to assist system administrators in mechanically
noticing compromised machines in their networks in an operational method. SPOT is an
operational and well-organized system in automatically distinguishing compromised machines in
a network and users of the SPOT structure can select the preferred thresholds to control the
incorrect positive and untrue negative rates of the system. Sequential probability ratio test has a
number of necessary features such as it reduces the probable number of interpretations required
to reach a conclusion amongst all the sequential and non-sequential statistical assessments with
no greater inaccuracy amounts. SPOT relies on the messages of spam as a substitute of infected
messages to become aware of that if a machine has been conciliated.
Keywords: Spam message, SPOT, Sequential probability ratio test, Infected messages.

The

sequential detection. Based on e-mail letters
expected at a large e-mail service supplier,
the recent studies examined the collective

comprising the size and the spamming
arrangements of botnets [4]. These recent
studies delivered significant awareness into
the collective global features of spamming
botnets by gathering spam messages that is
