The typo that can get you hacked

Here’s another reason to be extra careful about what you type into your web browser.

Cybersecurity firm Endgame has unearthed a new spin on the good old “typosquatting” scam — the practice of purchasing domain names similar to legitimate websites (Think Gooogle.com) in hopes that a small keyboard snafu nets hackers access to your computer.

The new scam aims to install malware on devices after users accidentally type “.om” instead of “.com” after popular urls. Endgame discovered the scheme after one of its employees mistakenly typed “Netflix.om” instead of Netflix.com when attempting to watch the latest season of House of Cards earlier this month.


Per a company blog post:

“He did not get a DNS resolution error, which would have indicated the domain he 
typed doesn’t exist. Instead, due to the registration of “netflix.om” by a malicious 
actor, the domain resolved successfully. His browser was immediately redirected 
several times, and eventually landed on a ‘Flash Updater’ page with all the usual 
annoying (and to an untrained user, terrifying) scareware pop-ups.”

After doing some more research, Endgame found the streaming service wasn’t the only popular url being “om’ed. Though some sites bearing that ending were legitimate, 319 .om domains appeared to have some type of scheme attached to them. (Fake Flash Updates, for instance, are commonly linked to a well-known malware named Genio that attaches itself to web browsers and mines for data.)

You can see a full list of the potentially dangerous domains here. It’s important to note you could also be in trouble if you typed the “c”, but misplaced the period. (Example: bestbuyc.om or cnnc.om.) This particular typosquatting game was easy for hackers to play, Endgame said, since “.om” is the country-specific domain name for Oman.

Protecting Yourself
Phishing and malware schemes are common attempts by scammers to get your personal information. For better Internet safety, it’s generally recommended you stick to trusted and encrypted websites (double-check, of course, the spelling of each address); refrain from clicking on links in unsolicited emails and keep your security software up to date.

It’s also good to monitor financial accounts regularly for fraud, and keep a close eye on your credit since a sudden drop in credit scores or unfamiliar line items on a credit report are signs identity theft is occurring. (You can do so by pulling your credit reports for free each year at AnnualCreditReport.com and viewing your credit scores for free each month on Credit.com.)  If have fallen victim to an Internet scam, you might also consider freezing your credit reports to keep new accounts from being opened in your name. And you can go here to learn what to do if you’ve already spotted identity theft on your credit report.

Surprise! Microsoft announces SQL Server on Linux

Microsoft has surprised the industry by announcing plans to bring SQL Server to Linux, a move that would accelerate the overall adoption of SQL Server.


“We are bringing the core relational database capabilities to preview today, and are targeting availability in mid-2017,” wrote Scott Guthrie, Executive Vice President, Cloud and Enterprise Group, Microsoft, in a blog.

Guthrie notes that SQL Server on Linux will provide customers with even more flexibility in their data solution.

“This is an enormously important decision for Microsoft, allowing it to offer its well-known and trusted database to an expanded set of customers,” said Al Gillen, group vice president, enterprise infrastructure, at IDC. “By taking this key product to Linux Microsoft is proving its commitment to being a cross platform solution provider. This gives customers choice and reduces the concerns for lock-in. We would expect this will also accelerate the overall adoption of SQL Server.”

“We believe our customers will welcome this news and are happy to see Microsoft further increasing its investment in Linux,” said Paul Cormier, President, Products and Technologies, Red Hat.  “As we build upon our deep hybrid cloud partnership, spanning not only Linux, but also middleware, and PaaS, we’re excited to now extend that collaboration to SQL Server on Red Hat Enterprise Linux, bringing enterprise customers increased database choice.”

“We are delighted to be working with Microsoft as it brings SQL Server to Linux,” said Mark Shuttleworth, founder of Canonical. “Customers are already taking advantage of Azure Data Lake services on Ubuntu, and now developers will be able to build modern applications that utilize SQL Server’s enterprise capabilities.”

The private preview of SQL Server on Linux is available already.

SQL Server 2016
Meanwhile, CEO Satya Nadella and other senior Microsoft leaders recently showcased Microsoft SQL Server 2016, the next release of the company’s flagship business analytics and data management platform, which will be generally available later this year.

Microsoft says SQL Server 2016 supports hybrid transactional/analytical processing, advanced analytics and machine learning, mobile BI, data integration, always encrypted query processing capabilities and in-memory transactions with persistence.

The new release’s security encryption capabilities enable data to always be encrypted at rest, in motion and in-memory to deliver maximum security protection.  In-memory database support for every workload with performance increases up to 30-100x.

SQL Server 2016 also offers business intelligence for every employee on every device – including new mobile BI support for iOS, Android and Windows Phone devices.

Advanced analytics using Microsoft’s new R support enables customers to do real-time predictive analytics on both operational and analytic data.

Microsoft also says that the SQL Server 2016 is available on Linux in private preview, making SQL Server 2016 more accessible to a broader set of users

Easy Migration
Microsoft also announced a new program to help more businesses move to SQL Server 2016. Businesses currently running applications or workloads on non-Microsoft paid commercial RDBMS platforms will be able to offset the costs of licensing, migration planning and training when moving to SQL Server 2016.  They will also be able to migrate their applications to SQL Server without having to purchase SQL Server licenses.

Linux Mint Website Hacked and ISOs replaced with Backdoored Operating System


Are you also the one who downloaded Linux Mint on February 20th? You may have been Infected!
Linux Mint is one of the best and popular Linux distros available today, but if you have downloaded and installed the operating system recently you might have done so using a malicious ISO image.

Here's why:
Last night, Some unknown hacker or group of hackers had managed to hack into the Linux Mint website and replaced the download links on the site that pointed to one of their servers offering a malicious ISO images for the Linux Mint 17.3 Cinnamon Edition.

"Hackers made a modified Linux Mint ISO, with a backdoor in it, and managed to hack our website to point to it," the head of Linux Mint project Clement Lefebvre said in a surprising announcement dated February 21, 2016.

Who are affected?
As far as the Linux Mint team knows, the issue only affects the one edition, and that is Linux Mint 17.3 Cinnamon edition.

The situation happened last night, so the issue only impacts people who downloaded the above-mentioned version of Linux Mint on February 20th.

However, if you have downloaded the Cinnamon edition or release before Saturday 20th, February, the issue does not affect you. Even if you downloaded a different edition including Mint 17.3 Cinnamon via Torrent or direct HTTP link, this does not affect you either.

What had Happened?
Hackers believed to have accessed the underlying server via the team's WordPress blog and then got shell access to www-data.

From there, the hackers manipulated the Linux Mint download page and pointed it to a malicious FTP (File Transfer Protocol) server hosted in Bulgaria (IP: 5.104.175.212), the investigative team discovered.

The infected Linux ISO images installed the complete OS with the Internet Relay Chat (IRC) backdoor Tsunami, giving the attackers access to the system via IRC servers.
Tsunami is a well-known Linux ELF trojan that is a simple IRC bot used for launching Distributed
Denial of Service (DDoS) attacks.

Hackers vs. Linux Mint SysAdmins
However, the Linux Mint team managed to discover the hack, cleaned up the links from their website quickly, announced the data breach on their official blog, and then it appears that the hackers compromised its download page again.

Knowing that it has failed to eliminate the exact point of entry of hackers, the Linux Mint team took the entire linuxmint.com domain offline to prevent the ISO images from spreading to its users.

The Linux Mint official website is currently offline until the team investigates the issue entirely.
However, the hackers' motive behind the hack is not clear yet.

"What we don't know is the motivation behind this attack. If more efforts are made to attack our project and if the goal is to hurt us, we’ll get in touch with authorities and security firms to confront the people behind this," Lefebvre added.

Hackers Selling Linux Mint Website's Database
The hackers are selling the Linux Mint full website's database for a just $85, which shows a sign of their lack of knowledge.

The hack seems to be a work of some script kiddies or an inexperienced group as they opted to infect a top-shelf Linux distro with a silly IRC bot that is considered to be outdated in early 2010. Instead, they would have used more dangerous malware like Banking Trojans.
Also, even after the hack was initially discovered, the hackers re-compromised the site, which again shows the hackers' lack of experience.

Here's How to Protect your Linux Machine
Users with the ISO image can check its signature in an effort to make sure it is valid.
To check for an infected download, you can compare the MD5 signature with the official versions, included in Lefebvre's blog post.

If found infected, users are advised to follow these steps:

  • Take the computer offline.
  • Backup all your personal data.
  • Reinstall the operating system (with a clean ISO) or format the partition.
  • Change passwords for sensitive websites and emails.

You can read full detail about the hack here. The official website is not accessible at the time of writing. We’ll update the story when we hear more.

Netflix has a black market for passwords, and they sell for just 25 cents

Attention Netflix users! Have you noticed odd activity in your ‘Recently Watched’ queue? There’s a possibility your account may have been compromised after a recent malware and phishing campaign targeting users has led to an influx of credentials for sale on the Dark Web for the low price of just 25 cents.


It’s long been known that hackers are nabbing and selling Netflix passwords, but a new report this week from security firm Symantec suggests the problem is growing following the streaming site’s recent international expansion to 130 new regions.

For hackers, the expanding membership base of Netflix, which is now available in a total of 190 regions globally, means there are more opportunities than ever to steal and sell passwords.

While the cost of a subscription for the streaming service already seems pretty reasonable when you look at the (legal) alternatives, the rise of the black market in Netflix passwords shows some people are willing to pay a lot less even if it means breaking the law.

According to Symantec, hackers grab passwords mainly through phishing attacks where a Netflix user is tricked into hitting a malicious link in an email or website that leads them unknowingly to a fake login page for the service. Malware is also being used to harvest account information, the California-based security firm said.

It also reveals that some cybercriminals are selling Netflix passwords on the dark Web for as little as 25 cents a pop. An ad lifted from the Web by Symantec shows a password vendor offering a minimum purchase of four accounts for a total of $1, adding that it has 300,000 passwords in stock. Its “terms of service” instructs customers not to change any account details as this would obviously alert the genuine subscriber to unauthorized activity.

Assuming the account details are indeed left untouched by the intruder, as a legitimate user you could still notice that your account’s been compromised if your “recently watched” list says you’ve already steamed through the entire season of Making a Murderer when you know darn well you haven’t (though why haven’t you?).

The video-streaming service now has 75 million users worldwide, a figure that indicates there’s plenty of potential for the black market in stolen Netflix passwords to expand and go on operating.

If you suspect that your Netflix account has been receiving an unwelcome visitor (or visitors), be sure to run a check:

  • Go to website haveibeenpwned.com. 
  • Check out the email address associated with your Netflix acount

Of course, if you’d rather be safe than sorry, you can skip that step and go straight to the fix: change your password. The important thing to remember is that you should change the password of any other account that uses the same one.

Warning — Setting This Date On iPhone Or iPad Will Kill Your Device Permanently

Don’t Try this at Home! An interesting software bug has been discovered in Apple's iOS operating system that could kill your iPhone, iPad or iPod Dead Permanently.



Yes, you heard me right.

An issue with the date and time system in iOS had emerged recently when Reddit users started warning people that changing your iPhone's or any iOS device's date to January 1, 1970, will brick your iPhone forever.

You can watch the whole process in the video given below. Even regular recovery tricks do not work


So, you are recommended to Not Try This Trick with your iOS device really – unless you book a trip to your local Apple Store.

While I don’t have any intention or desire to try it out with my iPhone 6s to confirm the authenticity of the bug, it is pretty much clear based on reports that seem legitimate.

YouTuber Zach Straley first discovered the issue, which was later confirmed by iClarified, who tested the trick on an iOS device.

Affected iOS Devices
This bug affects any iOS device that uses 64-bit A7, A8, A8X, A9 and A9X processors and runs iOS 8 or newer, including iPhones, iPads, and iPod touches. However, for those running on 32-bit iOS versions are not affected by this issue.

How the Bug Kills the iPhone?
Basically, the whole process is due to this:

  • Set up the date to January 1, 1970, via settings on your iOS device
  • Reboot your device, and you are done.
Your iPhone or iPad will no longer boot and will be stuck to the Apple logo. Even recovery mode restore or DFU mode will not let you restore your device; it will remain stuck on the bootup screen.


Your device will reportedly not come back, and the only way to get it back to work once again is to take your iOS device to an Apple Store.

The Only Way to Get Your iPhone Back
The bug is believed to be related to UNIX timestamp epoch that causes the kernel to crash. The only way to get it back is to open the device's casing and physically disconnect the battery from the logic board. This could only be done with the help of Apple's Genius Bar.

This process will reset the iPhone's date and allow it to boot.

While there isn't any other fix at the moment, Apple is expected to come up with a software update to fix and unbrick the affected iOS devices.

Though some users are saying that letting the battery drain could make the iPhone work once again, or changing the SIM card could fix the issue, or waiting for the device to back after 5 hours, you are still advised to not try this on your device as there is no guarantee these tricks are going to work.

'Critical' Israel power grid attack was just boring ransomware

Ransomware via a phishing attack hit Israel Electric Authority, not the power grid, but it still freaks out the world as the incident is dubbed a 'severe cyber attack;' that morphed in the media into an attack that took out the Israeli power grid.


Minister puts nation on alert, SANS Institute says move along, nothing to see here ...

The SANS Institute has moved to quell reports that Israel's energy grid has been hit by malware, revealing instead that the attacks were ransomware infecting the nation's utility regulatory authority.

Reports emerged after energy minister Dr Yuval Steinitz said a "severe" attack had hit the authority in what he reportedly called "one of the largest cyber attacks" the agency had experienced.

"We are handling the situation and I hope that soon, this very serious event will be over," Steinitz says.

Reports emerged suggesting the incident could impact the energy grid similarly to the targeted and sophisticated attacks against Ukraine, revealed earlier this year.

SANS security man Robert Lee says Israel-based analyst Eyal Sela of ClearSky Security says the reports are misleading.

"The Israel Electric Authority the Minister mentioned is in no way related to the networks of the Israeli electric companies, transmission, or distribution sites," Lee says.

"The Israeli Electric Authority is a regulatory body of roughly 30 individuals and this cyber attack is only referencing their networks.

"...new reporting shows that the cyber attack was simply ransomware delivered via phishing emails to the regulatory body's office network, and it appears it in no way endangered any infrastructure."

It is not known what ransomware infected the machines.

The latest versions of the most sophisticated malware – such as CryptoWall – cannot be removed without paying ransoms, while new and less-popular ransomware offerings contain encryption implementation flaws that allow the scumware to be removed without footing the extortion.
