Bitcoin falls after exchange is hacked, US$72 mil stolen from Bitfinex exchange in HK

Securing the bitcoin trading platform has proved elusive.


 
The price of bitcoin fell sharply today exacerbating an already ongoing decline as global market participants reacted to news that one of the largest digital currency exchanges had been hacked. Bitcoin Drops Nearly 20% as Exchange Hack Amplifies Price Decline


The price of the virtual currency bitcoin fell sharply after Hong Kong-based digital-currency exchange Bitfinex said it was hacked, resulting in the possible theft of about $65 million worth of bitcoin.

News of the Bitfinex hack hit the price of bitcoin hard in heavy trading on Tuesday. It fell to $540 by late in the day, down about 12% from its level near $613 early Tuesday, according to CoinDesk. At one point, it traded as low as $480, down about 22%, though it recovered to about $548 by late morning in New York on Wednesday.

The hack marks one of the largest thefts in bitcoin’s short history and follows a separate alleged theft of an estimated $60 million worth of ethereum, a rival virtual currency, in June. In 2014, investor confidence in bitcoin also was dented by another larger cybersecurity breach, at the Japanese exchange Mt. Gox.

Hacking and thefts of investor property stand as two of the biggest issues that may prevent the fast-growing digital currency from gaining more widespread use. Bitcoin trades on an open ledger known as the blockchain that has excited technologists for its ability to cut out expensive layers of bureaucracy in various areas of commerce.

But securing the bitcoin trading platform has proved elusive. Tuesday, Bitfinex acknowledged the latest theft in a statement on its website and said it was halting all trading on Bitfinex as well as the deposits and withdrawals of digital tokens.

“The theft is being reported to—and we are co-operating with—law enforcement,” the statement said. “We are deeply concerned about this issue and we are committing every resource to try to resolve it.”

Zane Tackett, Bitfinex’s director of community and product development, confirmed that 119,756 bitcoins were stolen and said the company knows “exactly how relevant systems were compromised.” At Tuesday’s value, the amount of bitcoin stolen was worth about $65 million. Mr. Tackett said the company is working with law enforcement and analytics companies to try to track down the stolen coins and is working to get its platform back up so customers can check their accounts.

It wasn’t clear what percentage of Bitfinex’s overall assets were stolen or whether or not the company had adequate insurance to cover the theft.

“We are investigating the breach to determine what happened, but we know that some of our users have had their bitcoins stolen,” the statement added. “We are undertaking a review to determine which users have been affected by the breach. While we conduct this initial investigation and secure our environment, bitfinex.com will be taken down and the maintenance page will be left up.”

In 2014, the Tokyo-based exchange Mt. Gox collapsed after a yearslong series of attacks resulted in the theft of about 850,000 bitcoins, at the time worth about $450 million. About 200,000 were later recovered. In June, Mt. Gox Chief Executive Mark Karpales was released from a Japanese prison on bail, after serving 10 months. The company’s liquidation is ongoing.

Bitcoin rallied earlier this year but had been selling off lately after an anticipated event known as a “halving” in early July lowered the subsidy paid to bitcoin miners supporting the network.

In 2015, Bitfinex switched to a system protected by what is known as “multiple signature” security, a feature that requires multiple “keys” to access bitcoin in a virtual wallet, and keeps the customers’ money in separate accounts, rather than pooling them into one larger account.

The exchange was fined $75,000 by the U.S. Commodity Futures Trading Commission in June for offering illegal off-exchange commodity transactions financed in bitcoin and other cryptocurrencies and for failing to register as a futures commission merchant. The CFTC said at the time that Bitfinex cooperated with its investigation and voluntarily made changes to its business practices to comply with regulations.

Bitcoin worth US$72 mil stolen from Bitfinex exchange in Hong Kong

HONG KONG (Aug 3): Nearly 120,000 units of digital currency bitcoin worth about US$72 million was stolen from the exchange platform Bitfinex in Hong Kong, rattling the global bitcoin community in the second-biggest security breach ever of such an exchange.

Bitfinex is the world's largest dollar-based exchange for bitcoin, and is known in the digital currency community for having deep liquidity in the US dollar/bitcoin currency pair.

Zane Tackett, Director of Community & Product Development for Bitfinex, told Reuters on Wednesday that 119,756 bitcoin had been stolen from users' accounts and that the exchange had not yet decided how to address customer losses.

"The bitcoin was stolen from users' segregated wallets," he said.

The company said it had reported the theft to law enforcement and was cooperating with top blockchain analytic companies to track the stolen coins.

Last year, Bitfinex announced a tie-up with Palo Alto-based BitGo, which uses multiple-signature security to store user deposits online, allowing for faster withdrawals.

"Our investigation has found no evidence of a breach to any BitGo servers," BitGo said in a Tweet.

"With users' funds secured using multi-signature technology in partnership with BitGo, a lot more is at stake for the backbone of the bitcoin industry, with its stalwarts and prided tech under fire," said Charles Hayter, chief executive and founder of digital currency website CryptoCompare.

The security breach comes two months after Bitfinex was ordered to pay a US$75,000 fine by the US Commodity and Futures Trading Commission in part for offering illegal off-exchange financed commodity transactions in bitcoin and other digital currencies.

BITCOIN SLUMP

Tuesday's breach triggered a slump in bitcoin prices and was reminiscent of events that led to the 2014 collapse of Tokyo-based exchange Mt Gox, which said it had lost about US$500 million worth of customers' Bitcoins in a hacking attack.

Bitcoin plunged just over 23% on Tuesday after the news broke. On Wednesday it was up 1% at US$545.20 on the BitStamp platform.

Tackett added that the breach did not "expose any weaknesses in the security of a blockchain", the technology that generates and processes bitcoin, a web-based "cryptocurrency" that can move across the globe anonymously without the need for a central authority.

A bitcoin expert said the scandal highlighted the risks of companies using cryptography for their ledgers.

"The more you rely on its benefits, the greater the potential for damage when keys are stolen. We still have some way to go to create highly secure but convenient systems," said Singapore-based Antony Lewis.

The volume of bitcoin stolen amounts to about 0.75% of all bitcoin in circulation.

It is not yet clear whether the theft was an inside job or whether hackers were able to gain access to the system externally. On an online forum, Bitfinex's Tackett said he was "nearly 100% certain" it was no one in the company.

Bitfinex suspended trading on Tuesday after it discovered the breach. It said on its website that it was investigating and cooperating with the authorities.

The security breach is the latest scandal to hit Hong Kong's bitcoin market after MyCoin became embroiled in a scam last year that media estimated could have duped investors of up to US$387 million. The bitcoin trading company closed after the scandal.

The president of the Hong Kong Bitcoin Association said the only way to protect information is to disperse it in so many small pieces that the reward for hacking is too small.

"For an attacker, the cost-benefit strategy is quite easy: How much is in the pot and how likely is it that I'm getting the pot?" said Leonhard Weese.

The attack on Bitfinex was reminiscent of a similar breach at Mt. Gox, a Tokyo-based bitcoin exchange forced to file for bankruptcy in early 2014 after hackers stole an estimated $650 million worth of customer bitcoins.  - Reuters

World's first Quantum communication satellite to be launched in China against hackers

China is poised to become the first country to send encoded information from space that cannot be hacked. Scientists are making final adjustments to China’s first quantum communication satellite. The project chief describes it as a revolution in communications.




 China will launch its first experimental quantum communication satellite in July, according to the Chinese Academy of Sciences.

China is poised to become the first country to send encoded information from space that cannot be hacked. Scientists are making final adjustments to China’s first quantum communication satellite. The project chief describes it as a revolution in communications.

A quantum photon cannot be separated or duplicated, which means if someone tried to decode information, the encryption would change, and the receiver would know that his letter was opened by someone.

Scientists hope the new technology will protect China from future cyber issues. In 2015, cases involving information technology in China rose by more than 120 percent, according to survey by a non-profit cybersecurity institution. China plans to use its quantum satellite system to cover the planet by 2030.

On the ground, China is also building its own quantum information sharing network for use in national defense and security. At some point, China plans to connect the ground network to the quantum satellite system.

It has taken five years for Chinese scientists to develop and manufacture the first quantum satellite. In June, it will be transported to the Jiuquan Satellite Launch Center in southwest China for final preparation and launch in July., 2016

Hackers in your heads, Cybercriminals preying on gullible


Cyberscammers tapping into minds - Conmen get personal data from social media


<< You’ve been had: A user checking an SMS alert about an unauthorised credit card transaction.

PETALING JAYA: Cybercriminals are getting into your head.

Realising that victims are no longer falling for the ‘I’m a Prince who wants to deposit US$50mil (RM199mil) into your account’ e-mail, these syndicates have enlisted psychologists and behavioural experts to launch targetted attacks on companies, groups and individuals.

By going through their victims’ social media accounts, they learn more about their targets and are able to craft attractive e-mail, prompting them to respond.

Clicking on the link in the e-mail will download malware that encrypts your device. Computers, smartphones, smartwatches and any other network-connected device, can be locked by cybercriminals who will only release it for a fee, or “ransom”.

Such ransomware has reached our shores, with a total of 5,069 attacks in Malaysia last year, according to cybersecurity company Symantec Corporation.

“The new modus operandi uses social engineering, with the e-mail being crafted by Malaysians who know the local scenario and how to trigger emotional reactions,” Symantec (Asia Pacific and Japan) cyber security services senior director Peter Sparkes told Sunday Star.

For example, if they find out from Facebook that you went shopping, you could get an official-looking e-mail from a trusted source like a government body or postal department saying: ‘You’ve received a free gift from shopping at our KL outlet. Click this link to trace your parcel’.

“Or if they see you at a cycling event, the e-mail could say: ‘Thank you for participating. Click on the link for photos and videos of the ride’,” he said.

“To decrypt your device, they’ll ask for about US$200 (RM782) in virtual currency like Bitcoin, to bypass the banks,” Sparkes added.

Acknowledging this new threat, Malaysian Communications and Multimedia Commission (MCMC) strategic communication head Sheikh Raffie Abd Rahman urged the public to be more alert.

He said one of the most commonly used social engineering techniques was phishing attacks targetting online banking customers.

Such cases would be investigated by the police under the Computer Crimes Act 1997 or the Penal Code.

A total of 1,311 phishing websites have been blocked by the MCMC between last year and March 8.

This includes fake pages created to acquire personal information such as usernames, passwords, banking information and credit card details by masquerading as a trusted entity in an electronic communication.

CyberSecurity Malaysia (CSM) chief executive officer Dr Amirudin Abdul Wahab said the number of incidents reported to the CSM indicates the growing threat of ransomware here.

Revealing that local businesses are also targeted, he said the CSM will work together with international communities to share current information on ransomware threats and disseminate them to the public.

Malaysian Mental Health Association deputy president Datuk Dr Andrew Mohanraj said cybercriminals have become more sophisticated in their approach by enlisting psychologists.

“But whichever methods they use, there is an underlying modus operandi of appealing to human emotions of fear, greed, curiosity, loneliness, compassion or even spirituality,” he said.

Cybercriminals preying on gullible


Users beware! With cybercriminals leveling up, ransomware attacks are expected to spike here. Malaysians shouldn't let their guard down when it comes to personal information and should be on the lookout for online scams.


HE wasn’t the fastest, but Eugene (not his real name) feels like a champion after finishing his first marathon.

Posting a selfie he made public on his Facebook account, the 28-year-old later receives an e-mail congratulating him on the feat. “Click on this link to see more pictures and videos of the event,” says the e-mail, which appears to be sent from the organiser of the run.

Curious and hoping to see images of himself, Eugene clicks open the link on his laptop but instead, gets a message telling him his device is now locked. All his files have been encrypted and he can’t access them, including his work document to be submitted on Monday.

The only way he can retrieve them is to pay a hacker a ransom of US$300 (RM1,181) in Bitcoin currency. Such an incident, known as a ransomware attack, could very well happen to you if you are not careful.

To top it all off, these cases are expected to increase this year, with “very specific ransomware targeted very specifically at Malaysians” being detected, says Symantec (Asia Pacific and Japan) cyber security services senior director Peter Sparkes.

According to cybersecurity company Symantec Corporation, Malaysia ranks 47th globally, and 12th in the Asia Pacific and Japan region, in terms of ransomware attacks.

Last year, there were 5,069 ransomware attacks or 14 per day in Malaysia. But Sparkes foresees that these numbers will surge.

“Ransomware is very attractive because it makes lots of money. It’ll be big here in the coming months, probably averaging 20 attacks per day.

“We’ve seen a lot of smartphone attacks recently. They love WhatsApp because the best way to get someone to click on a link is if it comes from someone you know,” he says.

Sparkes describes such crypto ransomware as the latest, and most dangerous malware threat because it’s near impossible to get rid of.

He adds that the experience is very emotional because many people do not back up their data.

“For individuals, losing personal data like photos and videos is traumatic so most victims will pay. Some will even tell you how to infect your friends to decrease your ransom,” he reveals.

Ransomware hackers are also using help from psychologists and behavioural experts to study their victims on social media before sending them personalised messages to trigger a response.

But it is not just ransomware that needs to be taken seriously as Malaysians need to be vigilant over social media scams, with these two being named as key trends in the country now by Symantec Malaysia systems engineering director David Rajoo.

He says cybercrime is extremely widespread with one in three Malaysians surveyed having experienced it in the past year and 83% know of someone else who was a victim.

“Consumers here lost an average of 27 hours and about RM8.9bil over the past year, dealing with the fallout of online crime.

“The amount of personal data stored online continues to grow, and while this free flow of data creates immense opportunities, it also opens the doors to new risks,” he warns.

Cybercriminals preying on personal data are also a cause for concern here and globally.

Sparkes points out that personal assistants and those in human resources are popular targets because that’s how cybercriminals gain access into an organisation’s database.

“Take a hotel for example. I’d target the CEO’s personal assistant. All I need is 200,000 of their best guests. If I sold the details at US$50 (RM197), it’s pretty good money for a day’s work. HR staff’s another good one because they look at CVs,” he says.

Last year, 500 million personal information was breached globally. That, he says, is a conservative estimate.

Someone checks out your Facebook activities, creates a personalised e-mail to get you to click on a link, and that’s it.

Everytime you download an app on social media, you could be giving access to your life, he cautions.

Of 10.8 million apps analysed in 2015, three million were collecting way more information than necessary, Sparkes says.

“Cyber scammers are also making you call them to hand over your cash,” he adds.

They send fake warning messages to devices like smartphones, driving users to attacker-run call centers to dupe them into buying useless services.

The services industry is the most vulnerable sector in the country, attracting 72.4% of spear phishing attacks.

There was also a significant spam increase with Malaysia jumping up the global ranking from 44 in 2014 to 23 last year, he adds, lamenting how many still don’t realise that cybercrime is an industry.

Cybercriminals are professionals using very sophisticated tools and techniques.

“They work like any other legit organisation – it’s a 9am to 5pm job with weekends off, holidays and proper offices. A lot of users still think it’s 18-year-olds in the garage fooling around. Nothing could be further from truth. The guys sell info to the underground economy,” Sparkes says.

Syndicates only need three things – cheap broadband, a cyber-savvy workforce they can hire, and countries where cyber laws are weak. Asia Pacific and Japan has invested significantly to give their population access to the Internet, he adds, explaining the shocking rise of cybercrime.

“I’m particularly concerned about the senior citizens as many are just discovering the Internet. They’re very trusting and will download without questioning. People stress on being streetsmart, but it’s just as crucial to be cybersmart,” he feels.
