Do you know how to protect your cryptocurrencies?

Imagen
By Moris Beracha .-  The bitcoins and the main cryptocurrencies in the market were designed with some important security patterns, which make them quite difficult to steal. The fundamental aspects of cryptocurrencies include protecting user privacy, avoiding asset theft and avoiding harmful practices such as double spending. However, there are some failures that are sought out by hackers, which allow them to take over and empty some accounts, leaving losses, in some cases, of thousands or millions of dollars. According to the Bit2me cryptocurrency and blockchain academy, about a billion US dollars in Bitcoin have been stolen to date. They recall the thefts in Mt Gt I and II, for a total of 769,408 bitcoins; the 173,655 bitcoins seized by the FBI when closing Silk Road; the robbery known as “Pony” Botnet, which stands out due to the number of machines involved, and which amounted to a total of US $ 220,000 in various types of cryptocurrencies th...

Ethereum Classic 51% Attackers Allegedly Returned $100,000 to Crypto Exchange

ETC Wallpaper - Ethereum Classic Cryptocurrency By Adrian Zmudzinski | Cointelegraph     The Ethereum Classic 51 percent attacker has reportedly returned $100,000 to cryptocurrency exchange Gate.io, a post on the official exchange’s blog reports on Jan. 12. The company further noted that they tried contacting the attacker but didn’t get any reply until now, and that they do not know the reason why the funds have been returned. The exchange declared: “If the attacker didn't run it for profit, he might be a white hacker who wanted to remind people the risks in blockchain consensus and hashing power security.” A white hat hacker is a hacker with a strong professional ethic who uses his hacking abilities for good and not for personal gain. The jargon file , a staple of hacker culture, further explains: “The term white hat [stands] for an ally or friendly security specialist.” On Jan. 9, Gate.io published their analysis of the 51 percent attack, fi...

Hackers From North Korea Targeting Bitcoin, Crypto Investors

Imagen
by   Nick Chong North Korea Still In Love With Bitcoin, Crypto Due to the decentralized, borderless, and censorship-resistant nature of  Bitcoin  and related technologies, North Korea, the world’s most well-known hermit state, has taken a liking to this decade-old innovation. But some would argue that North Korea has taken its crypto penchant a bit too far, with a multitude of reports indicating that the nation is leveraging cryptocurrencies for dubious financial gain. As reported by  Ethereum World News  in mid-October, Lazarus, a supposed North Korea-based hacker consortium, was found to be responsible for five cryptocurrency exchange hacks, including the now-infamous $500 million breach of CoinCheck. A report from cybersecurity firm Group-IB, who first divulged this information, indicated that Lazarus’ constituents used social engineering, phishing, and malware to forcefully visit pertinent databases and access points. Now, per the  South Chi...

Hackers Breach Smart Contract on Ethereum-Based Adult Entertainment Platform SpankChain

Imagen
By Helen Partz   Ethereum-based adult entertainment platform SpankChain has suffered a smart contract security breach that led to loss of around $38,000, the firm reported on its Medium page Oct. 9. The hack, which purportedly took place Oct. 6, was detected by SpankChain a day after, and was announced today in a post entitled “We Got Spanked: What We Know So Far.” Anonymous attackers managed to steal 165.38 Ethereum (ETH) or around $38,000 from the platform’s payment channel smart contract. Additionally, the security breach caused the immobilization of $4,000 worth of the SpankChain’s internal token called BOOTY. While most of lost or immobilized funds belong to SpankChain itself, the platform claimed that client reimbursements are of “immediate priority.” The company will shortly repay $9,300 worth of Ethereum and Booty coins directly to users’ SpankPay accounts via Ethereum airdrop. The SpankChain team has subsequently halted its camservice Spank...

Daniel Palmer After news broke yesterday of yet another hack of a cryptocurrency exchange in Japan, the country's police authority has released figures revealing the rise in such attacks this year. According to a report from The Asahi Shimbun Thursday, the National Police Agency (NPA) has released data for the first six months of 2018 that reveal cyberattacks on crypto wallets and platforms tripled over the same period last year. The NPA said that, through 158 cyber-breaches, hackers had stolen a massive 60.503 billion yen (around $540 million) worth of cryptocurrency.

The remainder – just over $22 million – was taken from individuals' crypto wallets. In what should be a lesson for us all in what not to do...

Bitcoin Investor Sues AT&T After Losing $23 Million In SIM Swap Hack

Imagen
By Lorenzo Franceschi-Bicchierai A cryptocurrency investor who says he lost $24 million after his phone number was stolen in two hacks wants AT&T to pay him more than $200 million in damages. Michael Terpin, founder of Transform Group and BitAngels, filed a lawsuit against AT&T on Tuesday. Terpin argues that AT&T didn’t do enough to protect his phone number despite the fact that the company was fully aware of the fact that criminals are increasingly targeting cryptocurrency investors by stealing their phone numbers in a fraud commonly known as SIM swapping, SIM hijacking, or “port out scam.” In the last few months, several criminals have stolen millions of dollars in Bitcoin or other virtual currency by targeting people who work in the cryptocurrency world. In July, police in California accused a 20-year-old of being part of a group who stole $5 million from more than 40 victims. A couple of weeks later, police in Florida charged a 25-year-old for similar crimes. ...
