  We report on the $XMM$-Newton observation of DW Cnc, a candidate intermediate
polar candidate whose historical optical light curve shows the existence of
periods at $\simeq 38$, $\simeq 86$ and $\simeq 69$ minutes which were
interpreted as the white dwarf spin, the orbital and the spin-orbit beat
periodicities. By studying the $0.3-10$ keV light curves, we confirm the
existence of a period at $\simeq 38$ minutes and find in the OM light curve a
signature for a period at $75\pm 21$ minutes which is consistent with both the
orbital and spin-orbit beat. { These findings allow us to unveil without any
doubt, the nature of DW Cnc as an accreting intermediate polar. The EPIC and
RGS source spectra were analyzed and a best fit model, consisting of a
multi-temperature plasma, was found. The maximum temperature found when fitting
the data is $kT_{max}\simeq 31$ keV which can be interpreted as an upper limit
to the temperature of the shock.
