There are three main modes of distribution for the major ransomware families that are poised to increase their attacks this year, security researchers warned on the occasion of Safer Internet Day on Tuesday.
One of the ways ransomware spreads is by replicating itself rapidly to other computers for maximum impact, researchers from cybersecurity firm Sophos said in a report “How Ransomware Attacks”, a playbook for defenders that explains how ransomware variants attack and impact victims.
Ransomware that spread by replicating itself is called a “cryptoworm”. The WannaCry attack that caused damage worldwide in 2017 is an example of this kind of ransomware. These malware also spread as ransomware-as-a-service (RaaS) which are sold on the dark web as a distribution kit (for example, Sodinokibi).
The third most common way of their spread is as automated active adversary attack, where attackers manually deploy the ransomware following an automated scan of networks for systems with weak protection.
This automated, active attack style was the most common approach seen among the top families listed in the report which includes detailed analysis of 11 of the most prevalent and persistent ransomware families, including Ryuk, BitPaymer and MegaCortex.
The research highlights how ransomware tries to slip unnoticed past security controls by abusing trusted and legitimate processes, and then harnesses internal systems to encrypt the maximum number of files and disable backup and recovery processes before an IT security team catches up.
“The creators of such attacks have a pretty good grasp of how security software works and adapt their attacks accordingly. Everything is designed to avoid detection while the malware encrypts as many documents as possible as quickly as possible and makes it hard, if not impossible, to recover the data,” said Mark Loman, Director of Engineering for Threat Mitigation Technology at Sophos, and the author of the report.
“In some cases, the main body of the attack takes place at night when the IT team is at home asleep. By the time the victim spots what’s going on, it is too late. It is vital to have robust security controls, monitoring and response in place covering all endpoints, networks and systems, and to install software updates whenever they are issued,” Loman said.
To protect against viruses, check that you have a full inventory of all devices connected to your network and that any security software you use on them is up to date, the researchers recommended. Always install the latest security updates, as soon as practicable, on all the devices on your network.

You should also keep regular backups of your most important and current data on an offline storage device as this is the best way to avoid having to pay a ransom when affected, the researchers said.
Administrators should enable multi-factor authentication on all management systems that support it, to prevent attackers disabling security products during an attack, they added. (IANS)

While smart homes are typically about connected and automated devices and appliances, making it a super convenient and comfortable living experience for residents, there is one connection that we often seem to miss when we speak of smart homes -- the inextricable connection with the indoor home environment.
After all, smart living is also about smart breathing. Unless we breathe clean and pure air even within our homes, smart living remains an incomplete aspiration. Therefore, as we pivot big time to a modern lifestyle with nearly 24/7 gadgets, utilities, and network dependency within our homes, a sense of balance with respect to the indoor ambiance must also be attained. And this balance necessarily means breathing pristine, unadulterated pure air even at homes.
Don't forget we breathe 24/7 even when living in smart homes
Of course, in this time and age when we are actively using some smart device or the other within the premises of our smart homes most of the time, the point that we are also breathing 24/7 need not be as labored. However, the question is: whether the quality of the air that we are breathing indoors is commensurate with the aspiration for this so-called quality of life and experience of living in high-class homes. In other words, even as we think we are living the 'high life' using all the fancy gadgets and increasing convenience in life, unless we breathe the right air, the desire and dream of quality living will not find true meaning.

Indoor air is worse than outdoor air
Contrary to the popular perception that the air quality in the external settings is worse than that of indoors, the reality is that indoor air is often found to be more impure and unhygienic for our health and living. This is not only because outdoor air gets natural circulation and revitalization as opposed to indoor air with a higher likelihood of getting stale by its very nature. But this is also based on solid scientific evidence. In fact, the levels of indoor air pollutants are often 2 to 5 times higher than outdoor levels and can even top the outdoor levels of the same pollutants 100 times in some cases. In these times of pandemic, it is worthwhile mentioning that even the transmission rate of the coronavirus is higher in indoor settings than outdoors.

Efficient energy use reminds us of the need for efficient human energy too
Smart homes naturally mean the most efficient and optimized energy use. There is a bit of irony in the fact that while we are living in an optimized energy-based setup, we are not optimizing our own energy here if we ignore indoor air quality. Breathing is a source of energy that sustains our body with oxygen, a life force that creates nearly 90 per cent of our bodily energy. If we wish to get the best of our breathing and internal energy system and indeed make everyday life and related pursuits more fulfilling, we need to breathe clean purified air all the time. A healthy life starts with breathing healthy air.

In a nutshell, unless we have indoor air purification -- of the smart kind or otherwise -- within our smart homes, even living in smart homes doesn't make us smart enough! (IANS/ MBI)

Shopping for others more than yourself
Some women only want to buy things from Chrome Hearts Official Store for themselves when they are shopping if it's something that isn't meant to be shared with anyone else. The worst thing you can do is go shopping just for your friends or family members. You don't want to buy clothing that the other person may not like or that doesn't look right on them just because you wanted to get them something! The three of you could be so much happier if one of you was left out and everyone got what they actually wanted.
Settling for second best
You should never settle for second best when buying something, even if it is a deal or at a discounted price because it still means someone else will get what you're looking for and another piece of clothing will end up in the wrong home where it won't be appreciated the way it deserves to be! So if you find a piece of clothing that has all the right pieces in all the right places, make sure to buy it and never settle for anything less because your wardrobe can only benefit from including things that are really worth having.
Shopping in haste
If you go shopping in a hurry due to not having much time or being rushed because someone is waiting on you then your choices will end up doing more harm than good when trying them on at home. You'll end up with clothing that doesn't fit perfectly or isn't what you wanted since you didn't have enough time to consider everything. So slow down and take your time whenever possible so there aren't any regrets later.
Failing to consider your current wardrobe
You want to avoid this mistake at all costs because it's just a waste of time, money, and energy when you know what you have is fine or that there are so many pieces in your closet that don't go together. You have to have some knowledge about the clothing you already own before getting something new. So take an inventory of what you already have so you can make informed decisions before buying anything else!

Buying things only because they're on sale
You may be so focused on getting a discounted price for items that aren't even your style or size which will just end up sitting in your closet unworn and wasting space because it doesn't fit right or look right because it wasn't meant to be. That's why you should only buy the best, most stylish clothing that fits your personal sense of style so there is no need to rush or settle for anything less!
Focusing too much on the price tag
You may end up passing over lots of things that are great deals, but not buying them because they don't have a high enough price tag making you think they weren't worth it even though you could get other pieces in your wardrobe without spending as much money elsewhere if you were shopping with a clear mind. The price tag doesn't mean everything when searching through your options for clothing!
Not checking how something will fit before buying it
This mistake can be a huge problem, especially when buying pants and skirts because you may not be able to return them or exchange them for something that will fit properly. You can't always trust the size on the tag so it's crucial to try clothing on before buying it whenever possible!
If you avoid these mistakes, then shopping can be one of your favorite things to do instead of another chore that just makes you angry at the end of the day because you didn't find anything worth having or spent too much money on what wasn't even right for you. So take your time every single time and never rush yourself by checking out all 10 mistakes so there are no regrets later!
