L’échange de bitcoins EXMO piraté pour 5% des actifs totaux

EXMO, une bourse importante en Europe avec un volume d’échanges de 45 millions de dollars au cours des dernières 24 heures, a été piratée aux premières heures de ce matin.

Le 21 décembre, la bourse EXMO a remarqué des retraits importants et suspects de son Bitcoin Code portefeuille très convoité.
5 % des actifs totaux de la bourse ont été volés par les pirates informatiques.

L’EXMO a constaté une faille de sécurité à 14h27 UTC le 21 décembre. Les pirates informatiques ont effectué des „retraits importants“, en volant les BTC, XRP, XEX, ESDT, ETC et ETH dans les hot wallets et en transférant les fonds hors site.

Les hackers de l’EXMO ont volé des bitcoins et des altcoins

Cinq pour cent du total des actifs ont été volés, tandis que les fonds de la „cold wallet“ restent en sécurité.

Les pirates ont retiré des fonds aux adresses suivantes :

  • USDT (ERC20) – 0xa910f92acdaf488fa6ef02174fb86208ad7722ba
  • ETH – 0x4BA6B2fF35055aF5406923406442cD3aB29F50Ce
  • CTB – 1A4PXZE5j8v7UuapYckq6fSegmY5i8uUyq
  • ZEC – t1StUQiw1YyHT515xDxwxjfhEcw2iGSq2yL
  • XRP – rwU8rAiE2eyEPz3sikfbHuqCuiAtdXqa2v (tag 2033412069)
  • ETC – 0x4d9EF6846126Da2867AF503448be0508542C971e

La bourse demande que tous les services et bourses bloquent les comptes liés aux portefeuilles énumérés ci-dessus.

L’EXMO a encouragé les utilisateurs à ne pas déposer de fonds aux adresses EXMO existantes. Le personnel de l’EXMO aurait redéployé les portefeuilles chauds dès qu’il a remarqué l’activité suspecte.

La déclaration d’échange indique qu’EXMO couvrira tous les fonds des utilisateurs touchés par l’incident.

Lutte contre la criminalité cryptographique

L’EXMO a signalé l’incident à la police de Londres et restera en contact avec le département de la cybercriminalité.

Malgré la maturation de l’industrie, les piratages de devises cryptographiques et les failles de sécurité se produisent encore.

4 milliards de dollars ont été volés en cryptocurrences au cours du premier semestre 2019, avec des incidents notables comme la chute de la bourse QuadrigaCX qui a entraîné la perte de 170 millions de dollars. Les autorités canadiennes pensent maintenant que QuadrigaCX était une chaîne de Ponzi.

En 2020, 50 millions de dollars ont été volés rien qu’aux projets DeFi. La société de renseignement CipherTrace rapporte que la criminalité liée à la cryptographie a ralenti cette année, bien qu’elle affirme que 1,8 milliard de dollars ont encore été volés au cours des dix premiers mois de l’année.

Alors que le secteur attire de plus en plus d’investissements institutionnels et de contrôles réglementaires, la question de la sécurisation des échanges et de la mise en place de mesures de sécurité au niveau des entreprises devient de plus en plus importante.

Three serious competitors for Ethereum in 2021

Ethereum has become the blockchain of choice for many developers of decentralized applications (dApp). Ethereum has by far the largest developer community, even surpassing Bitcoin’s. Still, there have been more and more serious projects recently that could erode Ethereum. The three most promising Ethereum competitors under the microscope.

After several years of development, the first phase of Ethereum 2.0 has started. The major upgrade has been in planning since 2015 and the fact that it is far more difficult to change the engine in a moving vehicle than to build from scratch speaks for itself. That is why many former ETH developers took the opportunity and developed their own blockchain. Will Ethereum lose its first mover advantage?

Cardano vs. Ethereum

Cardano (ADA) has been one of the most promising smart contract platforms in the crypto space for some time. The project was originally founded by mathematician Charles Hoskinson, a co-founder of Ethereum. Charles Hoskinson left Ethereum in 2014 and then created the for-profit IOHK Foundation.

The cryptocurrency ADA made more headlines this year as Cardano introduced the Shelly upgrade on its mainnet. Shelly enables Cardano to be staked and, similar to Ethereum 2.0, is just one of many phases. Shelly is only the second phase of the ADA update and three more upgrades will follow. In the end, Cardano should be a scalable blockchain on which smart contracts can also be programmed.

In addition, Cardano ultimately wants to operate an on-chain governance model in which every ADA holder should be able to participate. In the future, Cardano is expected to be best suited for applications in the finance and organization sectors. This is because, unlike Ethereum, Cardano is programmed in Haskell. Haskell is a programming language that is particularly suitable for business applications and data analysis.

Tezos vs. Ethereum

Tezos was founded in 2018 and the foundation behind Tezos, like Ethereum, is located in Zug, Switzerland’s crypto valley. Arthur and Kathleen Breitman developed Tezos. However, the early years of the blockchain project were often characterized by internal power struggles coined between the Breitmans and the Tezos Foundation.

Tezos uses a delegated proof-of-stake consensus mechanism that it calls “liquid proof-of-stake”. However, researchers have found that Tezos, while not having the same level of decentralization as Ethereum, is more decentralized than many other DPoS blockchains.

This is mainly due to the fact that Tezos has not prescribed an upper limit for the number of nodes. This makes it possible for Tezos to become more and more decentralized as it grows. In the future, Tezos and Ethereum 2.0 could definitely compete with each other in terms of security and decentralization. The main difference between the two blockchain projects is Tezos‘ on-chain governance model.

When the Breitmans conceived the Ethereum competitor, their vision was that the Tezos platform could upgrade itself. The goal is to create a competitive blockchain that can effectively evolve from within. Each Tezos holder can vote on what should happen next with the platform.

In contrast, Ethereum has always had off-chain governance. In all probability, this will not change anytime soon. However, it is unclear which system will prove to be superior to the other.

Incredible price promotion: Ripples XRP has increased by 200% since November

Ripple’s XRP has risen enormously in recent days as the coin is finally starting to catch up with Bitcoin and the decentralised finance (DeFi) market.

Despite the fact that the token has not experienced any fundamental events, it is still exploding higher and seems to be unstoppable on its upward climb. The coin has risen by over 50 per cent in the last 24 hours alone, reaching a price of $0.75, the highest in many years.

According to market data, Ripple’s XRP is the most powerful crypto asset in the top 100 in the last 24 hours – apart from Stellar Lumens (XLM), the cousin of the third largest crypto currency.

The coin on Coinbase briefly rose to $0.92 – just Coinbase, and it appeared that the market makers for the XRP markets on the stock exchange had run out of money – or that they had withdrawn their orders to maintain their books.

On other exchanges, Ripples XRP reached only $0.80, which shows how absurd this rally has been.

WTF? Ripples XRP is pumping?

The rally of Ripples XRP has caught many traders with their proverbial pants down.

Many openly admit on Twitter that they did not expect such a move to come so soon. Now the coin has risen by more than 200 per cent since the beginning of the month and basically surpasses all other altcoins except some DeFi blue chips.

Industry researcher Larry Cermak comments:

„Coinbase’s 10 per cent price increase notifications for XRP have literally sparked spamming on my phone in the last 24 hours. I don’t know what to make of this. Stupid money is here“

Many see this as a sign that the retail investors who drove the last crypto-bull run have returned.

Ripple’s XRP was basically a dead coin until the last three weeks.

The token set a series of lower highs and lows until late 2019, early 2020 and even well into the summer. Many thought the crypto currency would never recover.

Stellar also flies to the moon

Stellar Lumens (XLM), the coin launched by Ripple co-founder Jed McCaleb, is also shooting up.

The two cousins have long been going on rally in tandem, both with the „X“ at the beginning of their tickers.

XLM has gained 70 percent in the last 24 hours, making it the best performing crypto asset in the top 100 by market capitalisation.

Like Ripple’s XRP, XLM was largely behind other top Altcoins such as Ethereum and Litecoin in recent weeks. Many see this share price action as a fall back to the middle.

Hash War: Mystery Miner’s Empty Block Attack gjør ABCs nye Blockchain nesten ubrukelig

I følge ulike rapporter har Bitcoin ABC pro-IFP-kjeden vært under ‚angrep‘ i flere påfølgende dager nå. Mysterien har gruvet et stort antall sekvensielle blokker, men nesten alle har vært tomme. Gruvearbeideren som kaller seg ‚Voluntarism.dev‘, sier at gruvedriften er en gruppe „gamle gruvearbeidere“ og hevder at de kan rote med minoritets-ABC-kjeden i årevis.

‚Prisen på frihet er bratt‘

Kryptovalutasamfunnet har fulgt ettervirkningen av den nylige blockchain-forgreningen, som så Bitcoin ABC-noden gaffel i sin egen blockchain. Crypto Bank nettverket er fremdeles navnløst og uten merkevarebygging, og token blir ofte referert til som enten “ABC”, “BCHA” eller “BAB.”

Forrige uke rapporterte news.Bitcoin.com om en skjult gruvearbeider som har gruvet et stort antall påfølgende tomme blokker. Fordi blokker har vært tomme så lenge, har det vært vanskelig for noen å sende en transaksjon på ABC-kjeden og få transaksjonen bekreftet i tide.

Hash War: Mystery Miner’s Empty Block Attack gjør ABCs nye Blockchain nesten ubrukelig

Det antas at den mystiske gruvebassengoperatøren Voluntarism.dev kontrollerer 90% av ABC-kjedens hashrat lørdag 28. november 2020.

Siden nyhetsdeskens rapport har mystery miner introdusert gruppen på Twitter under kontonavnet Voluntarism.dev, og gjennom coinbase-parametermeldinger hver gang bassenget finner en ABC-blokkbelønning. 24. november 2020 opprettet Twitter-kontoen Voluntarism.dev en melding med en blockchain-signatur for å bekrefte legitimiteten.

Samme dag tvitret gruvearbeideren: “gode ideer krever ikke makt” og dagen etter twitret gruppen en melding til andre gruvearbeidere som pekte hashrate mot ABC-kjeden. Voluntarism.dev sa:

Jeg håper alle gruvearbeidere er enige: vi vil at 100% av BCHA-myntbase-belønningen skal gå til pqnqv9lt7e5vjyp0w88zf2af0l92l8rxdgnlxww9j9.
