  The field of particle physics is at the crossroads. The discovery of a
Higgs-like boson completed the Standard Model (SM), but the lacking observation
of convincing resonances Beyond the SM (BSM) offers no guidance for the future
of particle physics. On the other hand, the motivation for New Physics has not
diminished and is, in fact, reinforced by several striking anomalous results in
many experiments. Here we summarise the status of the most significant
anomalies, including the most recent results for the flavour anomalies, the
multi-lepton anomalies at the LHC, the Higgs-like excess at around 96 GeV, and
anomalies in neutrino physics, astrophysics, cosmology, and cosmic rays.
  While the LHC promises up to 4/ab of integrated luminosity and far-reaching
physics programmes to unveil BSM physics, we consider the possibility that the
latter could be tested with present data, but that systemic shortcomings of the
experiments and their search strategies may preclude their discovery for
several reasons, including: final states consisting in soft particles only,
associated production processes, QCD-like final states, close-by SM resonances,
and SUSY scenarios where no missing energy is produced.
  New search strategies could help to unveil the hidden BSM signatures, devised
by making use of the CERN open data as a new testing ground. We discuss the
CERN open data with its policies, challenges, and potential usefulness for the
community. We showcase the example of the CMS collaboration, which is the only
collaboration regularly releasing some of its data. We find it important to
stress that individuals using public data for their own research does not imply
competition with experimental efforts, but rather provides unique opportunities
to give guidance for further BSM searches by the collaborations. Wide access to
open data is paramount to fully exploit the LHCs potential.
