Hackers breached the Linux Mint website, Linux noted in a blog posting today. The Linux Mint 17.3 Cinnamon is the only compromised edition to the best of the company’s knowledge. Users who downloaded another edition or release are not affected. Users who downloaded via a direct HTTP link or via torrents are not affected either.
Since the breach occurred today, it should not affect users who downloaded the edition on Feb. 20.
Linux Gives Corrective Action
Users who still have the ISO file are instructed to check the MD5 signature posted on the blog with the “md5sum yourfile.iso” command where “yourfile.iso” is the ISO name. The blog page lists the valid signatures.
Those with the burnt DVD or USB stick should boot a virtual machine or a computer offline with it and let it load the live session. Users are encouraged to turn off their router if they are in doubt.
After the live session starts and there is a file in “/var/lib/man.cy,” the ISO is infected.
If the ISO is infected, the user should delete it. If they burnt it to a DVD, they should trash the disc. If burnt to the USB, the user should format the stick.
For those who installed the ISO on a computer, they should take the computer offline, back up personal data, reinstall the OS or format the partition, then change passwords for sensitive websites.
Linux took the server down while fixing the issue.
Entry Via WordPress
In response to a question, the blog’s editor said the hackers made the breach via WordPress.
The posting noted the hacked ISOs are hosted on 188.8.131.52 and the backdoor connects to absentvodka.com. Both lead to Sofia, Bulgaria, and there are three persons’ names. The motivation for the attack is unknown.
The posting said Linux will contact authorities if attacks continue.
People are still debating the hackers’ point of entry, according to Softpedia. While Clement Lefebvre, leader of the Linux Mint project, said the initial entry point was their WordPress blog, Softpedia noted that Yonathan Klijnsma, senior threat intelligence analyst at Dutch security firm Fox-IT noticed a few hours prior to Linux’s announcement that someone placed an ad on TheRealDeal Dark Web marketplace. Someone using the username “peace_of_mind” was selling “Linuxmint.com shell, php mailer and full forum dump” for 0.1910 bitcoin.
TheRealDeal Dark Web marketplace website was not accessible at 1:15 p.m. Eastern Standard Time.
MD5 Signatures Must Be Checked
The incident reminds users of the importance of checking MD5 signatures for critical downloads, according to Tim Anderson, writing in The Register. He said it is also important to be sure the MD5 signatures are from a trusted source instead of one hackers could have modified. These signatures are posted in more than one place in the case of a popular Linux distribution. Hence, signature consistency signals that something could be wrong.

Ethereum Notches Two-Month High as Bitcoin Offspring Triggers Volatility
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
It has been a difficult month for ethereum. The world’s No. 2 digital currency has lost a third of its value over the past 30 days following a series of cyber breaches targeting vulnerable wallets and ICOs.
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
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.
