The National
Cyber
Security
Centre and
the National
Crime
Agency
have
been
called
in
to
help Transport
for
London
deal
with
a
cyber
attack,
less
than
two
weeks
before
the
BBC
launches
a
drama
which
depicts
chaos
on
the
railways
after
computer
systems
have
been
penetrated.

Transport
for
London
says
transport
services
have
not
been
affected,
and
it
believes
details
of
customers
held
on
systems
like
the
Oystercard
database
are
safe.

This
morning
the
TfL
website
says:
‘We
are
currently
dealing
with
an
ongoing
cyber
security
incident.
At
present,
there
is
no
evidence
that
any
customer
data
has
been
compromised
and
there
has
been
no
impact
on
TfL
services.

‘The
security
of
our
systems
and
customer
data
is
very
important
to
us,
and
we
have
taken
immediate
action
to
prevent
any
further
access
to
our
systems.

‘We
are
working
closely
with
the
relevant
government
agencies
to
respond
to
the
incident.

‘We
will
update
you
further
when
the
incident
has
been
resolved.’

Earlier,
TfL’s
chief
technology
officer
Shashi
Verma
had
said:‘
We
have
introduced
a
number
of
measures
to
our
internal
systems
to
deal
with
an
ongoing
cyber
security
incident.
The
security
of
our
systems
and
customer
data
is
very
important
to
us
and
we
will
continue
to
assess
the
situation
throughout
and
after
the
incident.

‘Although
we’ll
need
to
complete
our
full
assessment,
at
present,
there
is
currently
no
evidence
that
any
customer
data
has
been
compromised.
There
is
currently
no
impact
to
TfL
services
and
we
are
working
closely
with
the
National
Crime
Agency
and
the
National
Cyber
Security
Centre
to
respond
to
the
incident.’

The
drama

Sleeper

of

to
London
which
is
sabotaged
by
a
device
inserted
in
the
Train
Management
System,
and
becomes
out
of
control.
The
series
starts
on
BBC1
on
