Someone Hijacks Botnet Network & Replaces Malware with an Antivirus

By on 5:35 AM
The Dridex banking trojan that is widely being used by cyber criminals to distribute malware onto users’ machines has now been found distributing a security software.

A portion of the Dridex banking Trojan botnet may have been hacked or compromised by an unknown Whitehat Hacker, who replaced the malicious links with Avira Antivirus installers.

What is Dridex Banking Trojan? How it Works?


Dridex malware – also known as Bugat and Cridex – is believed to have been created by cyber criminals in Eastern Europe in an effort to harvest online banking details. Even after a high-profile takedown operation in late 2015, the Dridex botnet seems to be active again.

The Dridex virus typically distributes itself through spam messages or emails that include malicious attachments, most often a Microsoft Office file or Word document integrated with malicious macros.

Once the malicious file has been clicked, the macros download and install the main payload of the virus – the trojan program itself – from a hijacked server, which installs and runs on the victim's computer.

The Dridex trojan program then creates a keylogger on the infected machine and manipulates banking websites with the help of transparent redirects and web-injects.

This results in stealing victim's personal data like usernames and passwords, with an ultimate aim to break into bank accounts and siphon off cash.

Hacker replaces Trojan with Anti-virus


However, the recent Hack Surprises: Instead of distributing banking trojan, a portion of the Dridex botnet currently seems to be spreading legitimate copies of the free anti-virus software from Avira, as the company has announced itself.

"The content behind the malware download [link] has been replaced, it is now providing [a legitimate], up-to-date Avira web installer instead of the usual Dridex loader," explained Avira malware expert Moritz Kroll, reported Reg.
Avira believes that the white hat hacker or hackers may have hacked into a portion of infected web servers using the same flaws the malware authors used and then replaced the malicious code with the Avira installer.

So, once infected, instead of receiving Dridex malware, the victims get a valid, signed copy of Avira antivirus software.

"We still don't know exactly who is doing this with our installer and why – but we have some theories," said Kroll. "This is certainly not something we are doing ourselves."

Although the motives behind including the Avira software is still unclear, these kinds of actions are considered to be illegal in many countries, said Kroll.

What can be done to protect From Malware Attacks?


The guidance for preventing yourself from being a part of the Dridex Banking Trojan botnet is:
  • Ensure you have an updated antivirus program running on your PC, which should be able to intercept the malicious attachments before they are opened.
  • One of the best measures for securing your online environment is to deploy an at the network layer, which is especially useful to quickly detect malware and other threats in your network when integrated with a and SIEM (Security Intelligence and Event Monitoring) solution, such as (USM).
  • Be careful of opening email attachments sent from an unknown email address, particularly (in this case) Microsoft Word and Excel files.
  • Disable Macros in MS Office, or at least set the Macros to request permission before they run.

MIT Develops Hack-Proof RFID Chip — Here's How It Works

By on 5:28 AM


Do you know about RFID chips and how many you are carrying at this moment?

Today, RFID chips are built-in all sorts of items, including your credit cards, travel swipe cards, library books, grocery store cards, security tags, implanted medical records, passports and even the access cards provided by companies.

But, What actually is an RFID chip?


Radio frequency identification (RFID) is a small electronic device consisting of a chip on which data can be encoded, and an antenna used to transmit that data. It is typically used for short-distance communication of information.


However, there is concern that these RFID chips could easily be hacked, and the information on these chips could easily be stolen by hackers. After all, they don't even require physical access to these chips in order to get data from it.

The good news is:


Researchers at MIT have developed a new way that prevents RFID chips from hacking.

Although the information on RFID chip is protected with a secret cryptographic key that could thwart a casual data thief, skilled RFID hackers have repeatedly used "Side Channel Attacks" to steal information from these chips easily.

Side Channel Attacks:


The 'side-channel attacks' are designed to extract the secret cryptographic key from a system by analyzing the pattern of memory utilization or fluctuations in power usage.



However, side-channel attacks only leak a little amount of information for each repetition of a cryptographic algorithm, so a hacker need to run the attack many numbers of times to get a complete secret key.

Power Glitch Attacks:


One way to prevent side channel attacks is to rotate the private key frequently after each transaction with the help of a random-number generator, but a skilled hacker can overcome this with a so-called "Power Glitch Attack."

Repeatedly cutting the RFID chip's power just before it changes the secret cryptographic key is known as power glitch attack.

By using this method, hackers can render the above strategy ineffective and run the same side-channel attack thousands of times, with the same key, in order to get the pattern and fetch the information from the RFID chip.

Here's How MIT Hack-Proof RFID Chip Works:


The new RFID chip developed by MIT researchers and manufactured by Texas Instruments is designed to block power glitch attacks, which is virtually impossible to hack by any current means, researchers claimed.

The new hack-proof RFID chip can resist power-glitch attacks by having:

  • An on-board power supply that is "virtually impossible to cut."
  • Non-volatile memory cells that store computations the chip is working on, even if there's a power cut.
This results in resuming of computation once the power gets restored.
"If that computation was an update of the secret key, it would complete the update before responding to a query from the scanner," the researchers wrote in a press release. "Power-glitch attacks won't work."
To achieve this, the new chip takes advantage of a material called Ferroelectric crystals that consist of molecules arranged into a lattice form where positive and negative charges naturally separate.

These ferroelectric crystals can operate as a capacitor for storing power, producing computer memory that retains data even when powered off.

The research team claims that if this high-security RFID chip hits mainstream adoption, it could help prevent contactless card details from being stolen, potentially preventing credit card frauds.

However, nothing is unhackable today, so calling something "hack-proof" or "virtually impossible to hack" doesn't make sense. As hackers nowadays are so skilled that even devices that are designed on the top of security features aren't immune to hacks.

However, new technologies, like this RFID chip, that take the security of users to the next level are always a good idea and importantly required to secure the world.

Juniper Networks will drop code tied to National Security Agency

By on 6:50 PM
Juniper Networks Inc said late on Friday it would stop using a piece of security code that analysts believe was developed by the National Security Agency in order to eavesdrop through technology products.
The Silicon Valley maker of networking gear said it would ship new versions of security software in the first half of this year to replace those that rely on numbers generated by Dual Elliptic Curve technology.
The statement on a blog post came a day after the presentation at a Stanford University conference of research by a team of cryptographers who found that Juniper's code had been changed in multiple ways during 2008 to enable eavesdropping on virtual private network sessions by customers.
Last month, Sunnyvale-based Juniper said it had found and replaced two unauthorized pieces of code that allowed "back door" access, which the researchers said had appeared in 2012 and 2014.
The 2014 back door was straightforward, said researcher Hovav Shacham of the University of California, San Diego, allowing anyone with the right password to see everything.
The 2012 code changed a mathematical constant in Juniper's Netscreen products that should have allowed its author to eavesdrop, according to Shacham and his fellow investigators.
Juniper's initial patch had gotten rid of that constant in Dual Elliptic Curve and replaced it with the version it had been using since 2008.
But the academics who studied the code said that while Juniper had not disavowed the 2008 code, it had not explained how that constant was picked or why it was using the widely faulted Dual Elliptic Curve at all.
Still another curve constant, quietly provided by the NSA and required for some federal certification, was exposed in documents leaked by former NSA contractor Edward Snowden as a key to the back door.
Until now, the most influential adopter of Dual Elliptic Curve was believed to be RSA, part of storage company EMC, which Reuters reported received a $10-million federal contract to distribute it in a software kit for others.
Though the academic team looking at Juniper has not named a suspect in the 2008, 2012 or 2014 changes, 2008 was one year after veteran cryptographers raised questions about Dual Elliptic Curve.
A very advanced adversary could have seen how to manipulate Dual EC and in theory managed to insert code through a cooperative or unsuspecting Juniper employee, but the company had not advertised the fact that it was using the formula at all.
A more logical suspect, said expert Nicholas Weaver of the International Computer Science Institute, was the NSA, which might have been displaced later by other countries' agencies or top-level hackers in 2012 and 2014.
The NSA did not immediately respond to an emailed request for comment.
Juniper said it was continuing to investigate. here

It declined to answer questions from Reuters about the revisions.

New Long-Range Wi-Fi Standard Offers Double Range to Home Devices

By on 7:43 PM


It is a common problem: Home Wireless Router's reach is terrible that the WiFi network even does not extend past the front door of the room.

My house also has all kinds of Wi-Fi dead zones, but can we fix it?

The answer is: YES. The problem will improve with a future, longer range version of Wi-Fi that uses low power consumption than current wireless technology and specifically targets at the internet of things (IoTs).

Global certification network the WiFi Alliance has finally approved a new wireless technology standard called 802.11ah, nicknamed "HaLow."

HaLow: Long Range WiFi


Wi-Fi HaLow has twice the range of conventional Wi-Fi and has the ability to penetrate walls that usually create blackspots in our homes.

The Wi-Fi Alliance unveiled this latest WiFi technology at the Consumer Electronics Show (CES) in Las Vegas.

Although currently used 802.11 Wi-Fi standards commonly operate in frequency bandwidths between 2.4GHz and 5GHz, the new WiFi HaLow was specially designed to work in lower bands, offering lower power consumption while boosting connectivity.

Wi-Fi HaLow can activate in the lower 900 MHz band, providing better propagation across longer distances while also coping with large numbers of devices connecting to a network.

WiFi HaLow: Designed now for IoTs


The HaLow standard is seen as an essential for the internet of things (IoTs) and connected home appliances. As more and more appliances in our homes are connecting to the Internet, it is quite harder for our home Wi-Fi wireless routers to reach every device.
"Wi-Fi HaLow is well suited to meet the unique needs of the Smart Home, Smart City, and industrial markets because of its ability to operate using very low power, penetrate through walls, and operate at significantly longer ranges than Wi-Fi today," said Edgar Figueroea, president of the Wi-Fi Alliance.
Several sensor-enabled and internet connected devices in our homes, like door sensors and connected bulbs, require enough power to send data to remote hubs or routers at long distances, but the current Wi-Fi standard does not lend itself to long battery life and transmission distances.

However, HaLow standard will likely offer slower throughput speeds than conventional WiFi that considers the smaller data demands of internet connected devices as opposed to those designed for web browsing.

HaLow Expected to be Useful For Devices From Connected Cars to SmartPhones


HaLow standard is expected to be especially useful in connected cars as well as battery-operated devices around the home like smart thermostats, smart locks, connected bulbs as well as mobile devices.
"Wi-Fi HaLow expands the unmatched versatility of Wi-Fi to enable applications from small, battery-operated wearable devices to large-scale industrial facility deployments - and everything in between," Figueroea said.
The WiFi Alliance is expected to begin certifying first products bearing a Wi-Fi HaLow certification in 2018, after which the technology requires to make its way into your home router, then into your wearable.

Microsoft WARNING — 'Use Windows 7 at Your Own Risk'

By on 7:41 PM

Someone is threatening Windows 7 users with a misleading warning.

Guess who? Microsoft itself…

Microsoft has just issued a clear warning saying Windows 7 users should remain on the aging operating system "at your own risk, at your own peril."

But why particularly Windows 7 Users?

Since Windows 7 runs on 55 percent of all the computers on the planet, Microsoft is worried that its goal to reach 1 Billion Windows 10 installations by 2017 could be harder.

During a recent interview with the Windows Weekly, Microsoft chief marketing officer Chris Capossela warned about the risks of using Windows 7 and urged users that it's time to switch to the new Windows 10 operating system instead.

Capossela also stressed that Windows 7 is apparently less secure than Windows 10, so it is "so incredibly important to try to end the fragmentation of the Windows install base" as well as to get them to a "safer place."

Here the so-called safer place Microsoft means is its newest operating system Windows 10.

Must Read: How to Stop Windows 7 or 8 from Downloading Windows 10 Automatically

Microsoft is Worried For us. Really?


Here’s what Capossela worried for Windows 7 Users:
"We do worry when people are running an operating system that’s 10 years old that the next printer they buy isn’t going to work well, or they buy a new game, they buy Fallout 4, a very popular game, and it doesn’t work on a bunch of older machines.

And so, as we are pushing our ISV [Independent Software Vendor] and hardware partners to build great new stuff that takes advantage of Windows 10 that obviously makes the old stuff really bad and not to mention viruses and security problems."
Do you notice any problem with Capossela’s statement? I did, the warning is entirely baseless.

There is nothing wrong with the security of Windows 7 as the operating system will be supported by the company until 2020, neither Windows 7 is less compatible with new hardware and software.

In fact, Windows 7 has a greater market share, which means the operating system is developers’ first choice over Windows 10 as well as the OS has greater compatibility with legacy programs and peripherals.

Fallout 4 not running on Windows 7 computers is also not true, as the blockbuster video game is fully compatible with Windows 7 and Windows 8 machines. Also, in case, the game do not run, no one will be installing Windows 10 to fix it, rather it will be upgrading your components.

Oh! Come On Microsoft, We Know...


The only reason behind this statement is Microsoft’s target of getting one Billion devices running Windows 10 by 2017 or mid-2018, and the motivation is quite clear with the following statement by Capossela:
"We think every machine that is capable of running Windows 10 we should be doing everything we possibly can to get people to move to Windows 10…We are going to try to find that right balance, but we just know there're many people out there who constantly kick the can down the street without a little bit more of a, frankly, push.

And so, there’s no doubt with a base as big as ours, it is hard to move anyone to a new model without angering some people. We don’t want to anger anybody, but we do feel a responsibility to get people to a much better place, and Windows 10 is a much better place than Windows 7. We will always give you a way out, but we’re trying to find the right balance."
This isn’t Microsoft’s first trick to force users to install its newest operating system. Microsoft previously tried a number of times to push Windows 10 more aggressively on systems running Windows 7 and 8.1.

Recently Microsoft announced its first milestone, noting Windows 10 is now officially installed on more than 200 Million devices worldwide since its launch five months ago.

Although there is nothing wrong with setting up a goal, but not respecting users choice and enforcing yours on them is completely not acceptable.
