It is possible that you have heard or read in the press, that some cryptocurrency attacks
had recently taken place.
It is true that the cryptocurrency world
is often targeted by hackers.
Is there a particular reason for this?
Let's take a look at the latest assaults and see if we can remedy the situation. security holes
or to bypass them.
The Celer Network attack
Celer Network, is a cryptocurrency
whose platform of the same name
aims to create decentralized applications that are easy to use and highly accessible.
On August 17, 2022, it will Cbridge
which has been targeted. The bridge to transfer cryptos between blockchains. These are the DNS
(Domain name service) that have been hijacked to create redirections of Internet users to the sites of hackers
without users noticing that they're no longer on the same website.
As a result, $240,000 disappeared in just 2 hours!
This amount is less than that of some attacks
As you can see in this article, only the users' cryptos were in the hackers' sights, not those in transit on the Cbridge
The attack of Wintermute
Wintermute, an intermediary of cryptocurrency
working in collaboration with the crypto trading platforms
was subjected, on September 16, 2022, to a cyber-attack
on a massive scale. The amount of cryptos stolen amounts to no less than $160 billion.
Once again, it's a case of Blockchain attack
This is because the elements of traditional centralized finance have not been targeted.
The security flaw
comes from an Ethereum address personalization tool called Profanity.
Using the public addresses (public keys) that had been personalized, it was possible to deduce the private keys of users' wallets and thus steal their cryptos.
That's why it's best not to use public key personalization tools, and to prefer the random address generation
However, it is important to note that the flaw does not come from the blockchain
but the use of an external tool.
The attack of the 44 platforms
On September 23, 2022, an employee of the dydx cryptocurrency exchange platform
has posted npm packages on Github
a software hosting and development company that has also become the world's largest online code repository.
One of the packages sent was present on no less than 44 digital finance platforms
The problem lies in the fact thatmalicious code was part of the package content
and that its purpose was to retrieve users' personal data and send it to an IP address abroad. It's easy to imagine that the accounts of a very large number of users could then be hacked.
Fortunately, a patch has been deployed as a matter of urgency. dydx
was able to reassure its users that their data had not been compromised.
According to a Chainalysis study cryptocurrency cyber-attacks
are experiencing a increase of 60 %
since the beginning of 2022 compared to 2021.
The FTX hack
No less than $600 million worth of cryptos were lost on the FTX exchange platform between November 10 and 12, 2022.
FTX CEO John Ray issued a statement under cover of his lawyer, indicating that there had indeed been a hack and that law enforcement had been seized.
Following the intrusion, FTX.com and FTX.us took steps to transfer their assets to cold (offline) wallets.
