Resumé:
Today telecom networks are pervasive and we rely on them for our daily
activities. So it is for cybercrime, for example, telecom fraud has been reported
to cost $40 billion globally[5]. This fraud takes very diverse forms, such as
Nigerian scams [6, 7, 8, 4], abuse of compromised PXB, routing phone calls on
'gray' networks or security agencies breaking into telecom operators [1].
In general telecom networks are an attractive target for criminals because
operations are always linked to billing (e.g., cashback phone numbers, termina-
tion costs, premium text messages, bulk SMS spam or denial of phone service).
Therefore, there are many ways that are used to manipulate networks and espe-
cially to extract revenue from those networks. While some commercial products
exist that attempt to mitigate such abuses, this eld was left mostly aside by the
research community. This is, in part, because the lack of access to equipment
or to the telecom networks themselves.
The goal of this PhD thesis will be to investigate the di
erent classes of
cybercrime and fraud on telecom networks, develop experimental tools for im-
proving the state of the art detection or prevention methods and to improve the
understanding of those cybercrime ecosystems. Examples of techniques that
may be experimented with are SIP and/or POTS (Plain Old Telephone Ser-
vice) based PBX honeypots, wardialing [2, 3] detection, etc.
The student will start by a performing a signi cant state of the art phase
which will help in identifying interesting directions. Finally, projects to pursue
will be de ned depending on resources available either in the Center or that
could be provided by MC (e.g., a range of phone numbers, SIP trunking, trac
logs, SS7 access...).
