TLDR
On
June
25,
2024,
the
Cardano
blockchain
faced
a
distributed
denial-of-service
(DDoS)
attack,
prompting
developers
to
initiate
a
node
upgrade
to
bolster
the
network’s
defenses.
The
attack,
which
began
at
block
10,487,530,
attempted
to
exploit
vulnerabilities
in
the
blockchain’s
transaction
fee
calculations
but
was
ultimately
unsuccessful.????
The
attacker
is
spending
0.9
ADA
per
transaction.
????
They
are
filling
each
block
with
many
of
these
transactions.
????
The
smart
contracts
used
are
of
type
REWARD.

The
swift
response
from
the
developer
community
meant
that
the
Cardano
network
was
not
compromised
and
continued
to
function
normally.
However,
Intersect,
a
member-based
organization
for
the
Cardano
ecosystem,
reported
that
the
network
experienced
higher
than
normal
load
during
the
attack.
Some
stake
pool
operators
(SPOs)
were
negatively
affected
due
to
an
increase
in
block
height
battles.
In
response
to
this
incident,
Cardano
developers
are
now
working
on
a
node
upgrade
to
enhance
the
network’s
security
against
similar
future
attacks.
Intersect
announced
that
once
a
solution
has
been
properly
tested
and
deployed,
they
will
share
the
new
node
version
for
SPOs
to
upgrade
to.
The
Intersect
task
force
is
collaborating
to
identify
and
test
solutions
that
will
minimize
the
impact
of
such
spam
attacks
in
the
future.
This
incident
highlights
the
ongoing
challenges
faced
by
blockchain
networks
in
maintaining
security
and
stability.
It
also
demonstrates
the
importance
of
having
a
responsive
and
skilled
developer
community
that
can
quickly
address
emerging
threats.
Disarro
emphasized
the
importance
of
thorough
testing
and
high-quality,
independent
audits
before
deploying
changes
to
production
environments.
“If
you
rush
to
deploy
something
to
production
without
thorough
testing
and
a
high-quality,
independent
audit,
you
might
wind
up
losing
a
lot
of
money
to
vulnerabilities
just
like
the
attacker
did,”
he
cautioned.
For
Cardano
users
and
investors,
this
incident
may
provide
reassurance
about
the
network’s
resilience
and
the
capability
of
its
developer
community.
