The latest entry to the roster of mega-breaches sees the revelation of a massive compromise of Dropbox user accounts. Altogether, over 68 million user account details were compromised, stemming from a 2012 breach. Late last week, Dropbox announced a mandatory password reset for a number of user accounts, specifically those created during or before mid-2012, when the breach occurred. While Dropbox did not reveal the number of accounts facing mandatory resets, the decision to reset passwords was taken out of precaution, Dropbox wrote recently.

The cloud storage provider had stated:

Our security teams are always watching out for new threats to our users. As part of these ongoing efforts, we learned about an old set of Dropbox user credentials (email addresses plus hashed and salted passwords) that we believe was obtained in 2012. Our analysis suggests that the credentials relate to an incident we disclosed around that time.

Based on our threat monitoring and the way we secure passwords, we don’t believe that any accounts have been improperly accessed. Still, as one of many precautions, we’re requiring anyone who hasn’t changed their password since mid-2012 to update it the next time they sign in.

However, a report by Motherboard has now revealed that the breach has affected a staggeringly large number of users. The publication obtained a number of files containing email addresses and hashed passwords from Dropbox users affected during the breach. A total of four files, weighing around 5GB, contained details on a total of 68,680,741 Dropbox accounts.

Notably, Motherboard also cites a senior Dropbox employee who remained unnamed, to confirm that the data is legitimate.

The data dump also threw up some insights into the type of password algorithms used by Dropbox in 2012. Nearly 32 million passwords were secured using bcrypt – a commonly used resolute hashing function. As a result, it is highly unlikely that malicious hackers or cybercriminals who obtain the data would be able to obtain the affected users’ actual passwords. The rest of the passwords are hashed with an aging SHA-1 algorithm. These passwords appeared with a salt to reinforce the password hashing process with a random string as a means to strengthen the password.

While one hacker told Motherboard that he or she had already gained possession of the data dump, it hasn’t surfaced in major dark web marketplaces, where such dumps are usually found. Fortunately, the bcrypt hashing function adequately secures passwords, diminishing their value in the cybercriminal market.

    Dropbox was already a pitstain on its customers anyhow! Dump that rubbish before it happens again, because they don’t do sh*t to secure/fix sh*t!

Ethereum Notches Two-Month High as Bitcoin Offspring Triggers Volatility

Published

on

Digital currency Ethereum climbed to a two-month high on Monday, taking some of the heat off Bitcoin and Bitcoin Cash, which have slumped since the weekend.

Ethereum Forges Higher Path

Concerns over Bitcoin created a favourable tailwind for Ethereum (ETH/USD), which is the world’s No. 2 digital currency by total assets. Ether’s price topped $340.00 on Monday and later settled at $323.54. That was the highest since June 20.

At its peak, ether was up 10% on the day and 70% for the month of August.

The ETH/USD was last down 2.2% at $315.02, according to Bitfinex. Prices are due for a brisk recovery, based on the daily momentum indicators.

Fractured Bitcoin Community

Bitcoin and its offshoot, Bitcoin Cash, retreated on Monday following a volatile weekend. The BTC/USD slumped at the start of the week and was down more than 3% on Tuesday, with prices falling below $3,900.00. Just last week, Bitcoin was trading at new records near $4,500.00.

Bitcoin Cash, which emerged after the Aug. 1 hard fork, climbed to new records on Saturday, but has been in free-fall ever since. The BTH was down another 20% on Tuesday to $594.49, according to CoinMarketCap. Its total market value has dropped by several billion over the past two days.

Analysts say that a “fractured” Bitcoin community has made Ethereum a more attractive bet this week. The ether token has shown remarkable poise over the past seven days, despite trading well shy of a new record.

Other drivers behind Ethereum’s advance are steady demand from South Korean investors and growing confidence in a smooth upgrade for the the ETH network. The upgrade, which has been dubbed “Metropolis,” is expected in the next several weeks. Its key benefits include tighter transaction privacy and greater efficiency.

Ethereum Prices Unaffected by ICO Heist

Fin-tech developer Enigma was on the receiving end of a cyber-heist on Monday after hackers took over the company’s website, mailing list and instant messaging platforms. The hack occurred three weeks before Enigma’s planned Initial Coin Offering (ICO) for September 11.

In addition to defacing the company’s website, the hackers pushed a special “pre-sale” ahead of the ICO. While many users realized it was a scam, 1,492 ether tokens – valued at $495,000 – were directed into the hackers’ cryptocurrency wallet by unsuspecting backers.

The irony in all this is that Engima is a cryptography company that prides itself on top-notch security protocols. The company issued a statement that its servers had not been compromised.

Ethereum Prices on Track for 35% Monthly Drop

Ethereum Struggles to Regain Momentum

Ethereum (ETH/USD) was trading near $197.00 Sunday at 6:30 BST, according to Bitfinex. That represents a decline of around 5%. At current values, ethereum’s market cap was $18.4 billion.

The ETH/USD exchange rate has struggled throughout July, with prices briefly falling below $160.00. The decline, which amounted to a 60-day low, lured bargain-hunters back into the market. After surging back toward $250.00, the ETH/USD has consolidated below the $220-mark, which continues to offer strong resistance. On the opposite side of the spectrum, major support is located at $180.00.

A price recovery may prove elusive in the short-term, with the Relative Strength Index (RSI) and Stochastic indicator signalling weak underlying momentum.

Despite its recent decline, ethereum’s value has surged more than 2,200% this year.

Cyber Attacks, SEC Weigh on Market

The ethereum network suffered a large-scale cyber breach earlier this month resulting in the loss of tens of millions of dollars. A community of ethical hackers quickly banded together to “rescue” hundreds of millions of dollars worth of tokens.

Blockchain-based trading platform Coindash was also hijacked during an initial coin offering (ICO). The breach exposed Coindash’s ether wallet address, resulting in the loss of $7 million worth of ether.

The Securities and Exchange Commission (SEC) has also taken an interest in the ethereum-based ICO market. Last week, the regulator concluded that a certain multi-million dollar token sale last year violated securities law. Although ICOs have been compared to crowd-sourcing, the SEC maintained that some tokens were in fact securities.

Analysts say the SEC ruling could impact the future of ICOs, although it remains unclear how the regulator is pursuing this market. The SEC’s July 25 press release cautions investors about ICOs in general.

Coders Safeguard Vulnerable Ethereum Wallets Following Security Breach

Published

hacker extortion bitcoin

Ethereum suffered large-scale security breaches last week after anonymous hackers targeted vulnerable wallets in the network, resulting in the loss of tens of millions of dollars. However, it didn’t take long for a volunteer group of coders to “rescue” the funds in 500 at-risk wallets before the same attackers could get to them too.

White Hat Group Takes Charge

The so-called White Hat Group showed initiative by “rescuing” the funds using the same techniques the thieves employed to compromise $32 million USD worth of ether from three multi-signature wallets. As of Monday, the White Hat Group of ethical hackers was in possession of $86 million worth of ether and an additional $122 million in tokens.

Tokens are digital assets that are sold during an Initial Coin Offering (ICO) fundraising event. They have proven to be extremely popular.

Tens of millions of dollars worth of ether and tokens have already been returned to their owners. The White Hat Group says it will issue full refunds by the end of July.

Blockchain-based trading platform Coindash was also breached last week, resulting in the loss of more than $7 million worth of ether.

Security Breaches Nothing New in Crypto World

For all its benefits, cryptocurrency has been vulnerable to several high-profile security breaches. Last summer, Hong Kong-based Bitfinex was the target of a major attack that resulted in the theft of around $70 million worth of bitcoins. In response, the exchange announced a controversial plans to “socialize” its losses among all users. Each Bitfinex trader was docked 36% as a result.

Bitcoin prices declined sharply following the attack, stopping what had been a blistering summer of gains.

Ethereum Enterprise Alliance

For anyone doubting the potential of the ether, take a look at the list of companies participating in the Enterprise Ethereum Alliance (EEA). The EEA is a forum that connects Fortune 500 companies, startups and academics with ethereum subject matter experts.  The EEA is made up of multinational banks and some of the world’s biggest technology companies.

The forum has made cyber security a top priority, according to a May 22 press release. In the release, companies like Infosys, Mitsubishi UFJ Financial Group, Synechron and others expressed their intent to contribute to the future of ethereum’s security.
