North Korea’s $571 million crypto hacks are just the tip of the iceberg

In a new report released by Group-iB, a cybersecurity intelligence agency, it has been revealed that 65 percent of the $882 million in cryptocurrency stolen from exchanges ends up in North Korea.

With sanctions from the United States and Europe continuing to weigh on Pyongyang, North Korea has reportedly turned to cryptocurrencies to generate additional revenue.

According to the report, North Korean hackers have stolen as much as $571 million since January 2017, making up nearly 5 percent of the country’s GDP.

The report notes that many of the attacks are tied directly to neighboring countries Japan and South Korea, including the $534 million hack of Japan’s CoinCheck, which has only recently resumed operations.

Though just a few of the attacks that have occurred over the past two years have actually been tied to a specific criminal organization, South Korea expects that North Korean hacker groups are likely responsible for many more.

The three branches of the DPRK’s hacking ecosystem

First, and most well-known, is the Lazarus Group, the supposed state-sponsored hacker group responsible for the Sony Motion Pictures hack, and according to some, the WannaCry attack which infected over 200,000 computers across 150 countries.

Lazarus has widely been blamed for many of the attacks associated with the North Korea’s cybercrime wave, but FireEye suggests that there may be two other groups which are casually flying under the radar.

FireEye believes that there are two groups that are specifically focused on cyber-espionage, targeting infrastructure, media outlets and the general population – the Lazarus Group and TEMP.Hermit – and one other group which is responsible for financial crime – APT38.

Similar toolsets and even overlaps in coding have linked the three groups to one another, offering a surprising insight into how organized and complicated the North Korean government’s efforts might be. The FireEye report also uncovers how precise and patient the groups are in their attacks.

With these tools and techniques, FireEye noted that the first activity from APT38 could be traced all the way back to 2014, the same time that Lazarus first hit the scene. And North Korea’s attacks are much further reaching than originally thought, directly targeting infrastructure and organizations in at least 12 countries.

Conclusion

While many of the exact details of the three organizations tied to Pyongyang remain scarce at best, it’s becoming abundantly clear that North Korea possesses a deep understanding of technology.

Last year, FireEye also reported the country had started mining cryptocurrencies around the same time sanctions on coal trade were enacted, suggesting that the regime could be using their most abundant natural resource to generate revenue despite the economic measures weighed against it.

Additionally, South Korean media outlet, Yonhap News, notes that there has been a significant uptick in cryptojacking activity, most likely tied to North Korea’s hackers.

While the DPRK has fallen out of favor with many international news outlets in recent months, it’s clear the country is still very active behind the scenes.

Trustlessness in Action: Particl's Model

Particl Thumb 5

“Trustlessness” is a term often
quoted as a feature of blockchain technology but what does that mean and is absolute
zero trust a myth or really true? Praised as one of the characteristics that
make the blockchain so revolutionary, a trustless system is one where two peers
can enter a virtual hand shake agreement, i.e.  smart contract, without relying on a
trusted third party to facilitate.

 

Blockchains are good at being
permissionless and having decentralized tasks that are recorded on an auditable
ledger, yet not all blockchains are completely trustless, and achieving full
trustlessness is challenging if not impossible.
Even
an open-source project like bitcoin that is constantly being reviewed can have
trust issues, not from the code but by the developers and reviewers of the
code. So trustlessness is more of a term describing an ideal state on the
blockchain where code is law with the caveat that humans write code and to err
is human.

 

Before looking at how a fully
trustless blockchain can be implemented by privacy advocates like Particl — an open-source project that is building
a decentralized ecommerce application on the blockchain — let’s look at the
obstacles standing in the way.

 

I Trust
You, Until I Don’t

 

We’re conditioned to think of
trust as a good thing. Traditionally, positive human relationships have
required a level of trust.
From an economic perspective, however, trust has significant
downsides.

 

The greatest drawback is that trust
can be broken. When you engage in a transaction with someone you believe to be
trustworthy, but then they fail to deliver the promised goods or services, you
suffer.
In
addition, trust is not efficient. It has to be cultivated and you have to
invest time in evaluating how much another party can be trusted before you
engage in a trade.

 

Blockchain technology can be
leveraged to overcome the risks and inefficiencies that are associated with
trust.
With
the right approach, it’s possible to make reliable transactions on the
blockchain without knowing or trusting the person or group you are dealing with.
That is because the blockchain can be used to enforce good behavior.

 

In Particl’s case, by creating
a simple smart contract, you can ensure that if one party in a transaction
fails to uphold their end of a deal, the blockchain can automatically cancel
the transaction or punish the misbehaving party in another way. In effect, this
feature makes it impossible for a malicious user to profit by taking advantage
of the trust that another user places in them without inflicting harm on
themselves as well.

 

The
Trustless Challenge

 

If you buy or sell something
using bitcoin, you don’t automatically gain protection against being cheated: default
bitcoin transactions are non-reversible. The ability of the blockchain to
enable transactions that are both trustless and reliable is difficult because
it needs to be done without the intervention of a third party. In conventional
trading contexts, transactions are typically policed by a central authority that
evaluates claims about broken trust and responds accordingly. For example, if a
seller cheats you on eBay, you can complain to eBay and request a refund. These
authorities also charge fees or percentages of sales revenue whether they are
used or not.

 

The downside to this approach
is that it compromises privacy. In order to provide this protection against
broken trust, a platform like eBay oversees transactions. It knows what buyers
and sellers are doing.
With a two-person trustless escrow, in contrast, reliable
transactions can be implemented without the oversight of a third party. You
don’t have to lose privacy to gain reliability.

 

The tricky thing about
achieving true trustlessness on a privacy-focused blockchain is that it doesn’t
happen by default. Although multiple times more efficient than building trust
in public, smart contracts still need to be signed and the exchange of goods or
services still needs to happen. The beauty is that an agreement can be made and
successfully carried out even if one or both parties don’t fully trust each
other.

 

A Trustless
Solution

 

Particl leverages bitcoin as
the underlying blockchain protocol, but adds privacy enhancements that make it
possible for users to perform transactions that are trustless, reliable and
private. In an innovative development, PART transactions do not require users
to write smart contracts themselves. Instead, this feature is built into the
platform.

 

Central to Particl’s approach
to trustless transactions is mutually assured destruction (MAD) escrow. MAD
escrow
is a special type of smart contract that prevents either party from
profiting in the event that one cheats during a transaction.

 

In addition, because the smart
contract is enforced automatically via the blockchain, Particl developers play
no role in overseeing transactions. Their platform guarantees privacy while
achieving trustlessness at the same time. Two people from anywhere in the world
can enter into a binding agreement that is only finalized when both agree it is
completed.

 

Blockchain technology’s promise
is that users are no longer bound by the inefficiencies and risks associated
with trust in order to make transactions. Most blockchains, however, do not yet
implement truly trustless transactions. Particl is an exception, as it was developed
with trustlessness at its core from the start. Particl developers aim to “square
the circle” by delivering trustless ecommerce without compromising reliability
or privacy.
