Why is the ETC Price Steady Despite Risk of Further 51% Attacks?

Despite suffering its second 51% in a week, and major exchanges disabling deposit, withdrawal, and some trading services, Ethereum Classic is up 2% over yesterday. After suffering two major blockchain reorganizations over the past week, Ethereum Classic  (ETC) has seen its hash rate plummet — exacerbating the risk of further 51% attacks targeting the network. As a consequence of the ETC’s miner capitulation, the estimated cost of executing a 51% attack targeting Ethereum Classic using hash power rented from NiceHash has fallen from $12,000 per hour as of yesterday to less than $4,000, according to Crypto51. Despite this, the price has been unaffected by the apparent fragility of the network, with the crypto asset actually gaining more than 2% over the dollar since news of the second reorganization attack broke yesterday to currently trade for $7.21. Exchanges report $800M in 24-hour ETC volume  24-hour trade volume is up roughly 10% from the level posted only a few days before the first 51% attack, with orders continuing to execute across most top exchanges, including Coinbase Pro, Binance, Okex, Bitfinex, and KuCoin. The increase in trade activity comes despite the suspension of withdrawal, deposit, and margin funding services among a number of leading crypto exchanges.  ETC posts wishy-washy market signals The strength of ETC’s markets despite exchange’s having disabled wallet activity raises questions about whether algorithmic bots may be driving much of the current trade activity. In 2019 a report published by Blockchain Transparency Institute estimated that Ethereum Classic was among the three-most wash-traded crypto assets — with more than 80% of volume having been flagged as suspicious. Ethereum Classic miners capitulate After hovering between roughly five and six terahashes per second (TH/s) through July, ETC’s hash power dropped to approximately four TH/s over the past seven days after news of the initial 51% attack broke

Ransomware Threatens Production of 300 Ventilators Per Day

The DoppelPaymer gang deployed a ransomware attack against ventilator manufacturer Boyce Technologies amid the COVID-19 pandemic. The FDA-approved Coronavirus ventilator manufacturer Boyce Technologies has been targeted by ransomware launched by the DoppelPaymer gang, who are  threatening to leak data from the company. Cointelegraph has viewed the DoppelPaymer blog, where the gang lists example files of the data stolen during the attack, including sales and purchase orders, assignment forms, among others. The cybercriminals have threatened that more information will be disclosed next week through the site if an undisclosed crypto ransom is not paid by the firm. Boyce Technologies is well-known for its work in designing and manufacturing FDA-approved low-cost ventilators in just 30 days during the first months of the COVID-19 pandemic, amid the big demand for the machines across New York hospitals. Prior to the attack the company was making 300 units a day with the help of the robots built by the company. Healthcare sector under threat despite COVID-19 pandemic Speaking with Cointelegraph, Brett Callow, threat analyst and ransomware expert at malware lab, Emsisoft, warns that such attacks on hospitals, medical testing labs, and medical device manufacturers may not only cost money, “they may cost lives as well.” He adds: “Unfortunately, ransomware will continue to be a problem for as long as ransoms continue to be paid, and this is something organizations should keep this in mind.

Forensic analysis suggests the recent Ethereum Classic blockchain reorganization was a carefully orchestrated malicious attack. A recent 51% attack that impacted Ethereum Classic (ETC) is believed to have resulted in approximately $5.6 million worth of the cryptocurrency being double-spent. A report published by Aleksey Studnev of blockchain forensics firm Bitquery on August 5 has revealed the extent of the incident, with Bitquery estimating that the attacker made off with 807,260 ETC. The report estimates the hacker reaped more than a 2,800% return for his efforts, having spent roughly 17.5 Bitcoins (BTC) worth $192,000 on renting hash power from Nicehash to execute the attack. The report contradicts initial theories suggesting that the blockchain reorganization may not have been intentional. Sophisticated double-spend  The attack took place between July 31 and August 1, however, was not detected for several days as a result of intricate planning and knowledge of the Ethereum Classic protocol.

Defending Bitcoin’s Integrity in the Great Twitter Hack

The recent Twitter hack has placed the words “Bitcoin” and “scam” in one headline again, though Bitcoin has nothing to do with it. Bitcoin (BTC) has made global headlines again because of the recent Twitter hack, but this time, we need to work harder to protect Bitcoin’s integrity and the progress the industry has made. The coordinated social engineering attack compromised the Twitter accounts of high-profile figures and organizations like Microsoft co-founder Bill Gates, Tesla founder Elon Musk, Amazon owner Jeff Bezos, former United States President Barack Obama and 2020 US presidential candidate Joe Biden, among many others, to ask for Bitcoin in fake “giveaway” posts. When the story broke, the New York Times, BBC and other mainstream media outlets were quick to label the incident a “Bitcoin scam” or “crypto scam.” To have “Bitcoin” and “scam” used in the same breath in the global media may feel like all the work that’s gone into building trust for this revolutionary technology since its creation in 2009 has been for nothing. This is even more reason why companies and their communication teams must turn the publicity Bitcoin is getting now into a positive for the industry. Set the record straight: Bitcoin is not to blame The first point to clarify with the media, friends, family and newcomers is that this is a high-profile Twitter hack. This is not a “Bitcoin hack,” not a “Bitcoin Twitter hack” nor even a “Twitter Bitcoin hack” — as described by The Evening Standard and even Wired — because Bitcoin did not get hacked, nor did Bitcoin cause the hack. It’s even more concerning to see The Late Show with Stephen Colbert describe the hackers as “Bitcoin Bandits,” when the motives of the hackers have not been confirmed. Twitter is a centralized organization; it holds all users’ data and accounts in one place.
