The
Cardano
blockchain
successfully
defended
against
a
Distributed
Denial
of
Service
(DDoS)
attack
aimed
at
stealing
staked
tokens.
The
attack
had
little
impact
on
ADA’s
value,
up
by
a
modest
0.4%
during
the
last
24
hours
to
$0.38
as
of
press
time,
according
to
CryptoSlate’s
data.
Attack
details
On
June
25,
Fluid
Token’s
CTO,
Raul
Antonio
Rosa
Padilla,
reported
that
the
blockchain
suffered
an
attack
at
Block
10,487,530.
According
to
him,
the
attacker
attempted
to
overload
the
network
by
spending
0.9
ADA
per
transaction,
targeting
194
smart
contracts
with
multiple
transactions
per
block.
Despite
this,
Cardano’s
network
maintained
normal
operations,
resulting
in
the
attacker
losing
funds
instead
of
stealing
them.
Phillip
Disarro,
founder
of
Anastasia
Labs,
a
Cardano-based
development
company,
suggested
that
users
could
help
stop
the
attack
by
deregistering
any
of
the
194
stake
credentials
used
by
the
attacker.
He
highlighted
deregistration
as
the
quickest
method,
rewarding
users
with
2
ADA
tokens
per
credential
until
the
attacker’s
400
ADA
was
exhausted.
Disarro
stated:
“Just
to
clarify,
the
network
is
behaving
as
intended.
Liveliness
is
unaffected.
Everything
(block
size
limit,
transaction
size
limits,
block
times)
are
all
set
so
conservatively
that
any
attack
on
liveliness
is
a
total
waste
of
funds.
Even
with
validators
deserializing
194
junk
scripts
(~16kb
each)
per
transaction
the
validators
are
totally
fine
processing
these
transactions
(which
involve
deseralizing
roughly
200x
what
they
are
used
to).”
Following
Disarro’s
post,
the
DDoS
attacker
ceased
their
efforts
to
prevent
further
financial
losses.
Disarro
noted
the
irony
that
the
attacker
inadvertently
funded
open-source
development
work
at
Anastasia
Labs
and
Midgard.
While
the
blockchain
continued
to
operate
normally,
Intersect,
a
Cardano
membership
group,
reported
that
the
attack
negatively
impacted
some
stake
pool
operators
(SPOs).
However,
efforts
are
ongoing
to
identify
solutions
to
prevent
future
occurrences.
The
group
remarked:
“The
network
has
experienced
a
higher
load
than
normal
and
some
SPOs
have
been
negatively
affected
due
to
an
intensification
in
block
height
battles.
However,
the
chain
as
a
whole
is
functioning
as
expected,
with
only
a
small
impact
on
overall
transaction
timings
and
some
reduction
in
chain
density.”
