What are the risks of getting infected by malicious software?

11 Replies Alan

Have you ever thought of what is going to happen when you are infected by a computer malware? About a decade ago, computer virus aims were to replicate themselves and destroying key operating system functions. If you got a computer malware infection at that time, most probably your operating system will be corrupted by the malware and you will need to format your hard disk to solve your problem.

Today, malicious software behaves a little different. We have more than 10 types of computer security threats such as virus, trojan, worms, spyware and many more. Each type of malware has their own speciality and here are top 3 risks of getting infected by a computer malware.

1. Having your login credentials stolen

It is very popular today that a keylogger/keystroke logging is used to log a victim’s login credentials. Once the keylogger has a set of your username and password, they can login into the account and do almost everything unless your account is protected by a two factor authentication.

2. Losing hard disk space

Hard disk space today can be very cheap but we should not waste it on storing malicious software. Malware such as worms will replicate in your operating system and take up your hard disk space. You will not feel the burden at the beginning but as the process gets longer, you will start to feel the pain of having insufficient disk space.

3. Spending money on unnecessary stuff

There is also a type of malware where they scare you off by telling you that your computer has hundreds of infections which you actually don’t have. Upon scaring you, they urge you to purchase a bogus antivirus which claims that can clean all the mentioned infections. All in all, you end up actually paying for nothing.

4. Being part of a minion for DDoS attack

Have you ever thought of how DDoS can bring thousands to millions of traffic to a server? It is actually all the computers which are infected with some sort of trojan that explains how the attacker can have such massive amount of traffic. By getting a malware infection, you are at risk of becoming part of this big project which you do not want to be.

5. Losing your privacy

Another form of malware which is known as spyware is built to spy your daily activities. By knowing your daily activities, the attacker will be able to understand you better before attacking you. For instance, if you regularly surf to adult sites, the attacker will probably start off with some fake adult material to lure you into their trap.

Looking at someones internet usageBack to you now, are you able to take all the risks mentioned? If you are not, be sure you have a good habit when it comes to internet and computer security and always remember that having an antivirus and firewall is not sufficient for a good security.

Injections Without Needles

If there is one thing I don’t like it is getting an injection. I have never had a flu shot (but never had the Flu) and part of the reason is the needle effect.

This may all be coming to an end though as scientists here at MIT have devised a way to inject medicine without a needle. See this article for a description.

Needle free injection

The new MIT developed needle-less system

This is not the first time that such a development has been publicized, but a technological and practical leap forward has been made. The MIT system is new in that it can deliver medicine at different depths. This means that medicines can now be inserted into muscle or fatty tissue at will and with ease.

The system uses magnets to achieve delivery, and this is the breakthrough that makes the system so interesting. Needle-less systems have been available for some years now, but they tend to rely on compressed air and are not flexible in terms of pressure. They medicine enters the body but the depth is not variable.

The MIT device works electrically and the pressure is absolutely flexible, allowing the operator to change the pressure of entry but then also lower it to enable distribution to the surrounding tissue. In other words lower pressure can be used to pass through the skin of a child, a process that does not require the same force as passing through an adult’s skin. The pressure can then be lowered to enable the distribution of the medicine to the surrounding cells once already in the body.

This breakthrough means that medication can be passed through other parts of the body too, for example through the eye tissue and directly into the retina or through the ear drum.

As you can see the importance is not really in my dislike of needles but in the loss of the needle.

Needle injuries are common for health workers, and with this system they are removed from the equation once and for all. No more accidental cross infections!

There are also obvious advantages for people that have to inject themselves daily for example in the case of diabetes.

Several major drugs companies have expressed an interest in developing and marketing the product so it looks like the days of the needle might be numbered.

I don’t know if it still hurts a bit though.

Is remote working the future for business?

7 Replies Christopher Roberts

In previous articles I have talked about how technology and business interact, and what the future of technology might hold for the world of business. In this article I am going to explore the idea that in the future, almost all business will be conducted remotely.

The number of people who permanently work at home in the UK, (known as teleworking) was estimated to be 1.3 million in 2010. The working population of the UK at the same time is believed to be around 30 million, therefore around 4.5% of the UK’s population (in 2010) were teleworkers. That said, is is estimated at the same time that 3.7 million UK workers sometimes worked from home, and sometimes went into their place of work. That means that of the working population, around 12.5% were, at some point, working remotely.

The figures are similar for the USA, and other developed nations. More and more firms around the world, are offering their employees the opportunity of working from home, but why?

Cost Advantages

Many people do not realise it, but it is often much cheaper to give employees access to the technology they need to work at home, than it is is to provide them with a workstation in an office unit. Yes that might mean you need to buy every employee a laptop, printer and make sure they have an internet connection, however that is often much cheaper than maintaining a workstation, in a fixed location.

If employees work in an office, then the firm either has to purchase or rent the premises – this can be very costly. Furthermore, an (often very expensive) IT mainframe system needs to be in place, to ensure that the entire building is connected internally, and with the outside world – including offices in other locations. Most employees will need a computer to work at, so why not buy them a laptop, give them their own printer, make sure they are internet connected, and tell them to work from home? It is often much cheaper.

Technological Advancements

Improvements in technology mean that working from home is more viable than ever before. Thanks to online storage systems, which allow simple, easy and effective file sharing among workers, employees are able to connect with each other, and share data from almost anywhere in the world. Outsourcing such tasks is often a much cheaper option for firms, than maintaining their own expensive IT infrastructure.

Advancements in communication technologies have also improved the viability of teleworking. I have previously wrote about QB Robots, robots which are effectively your eyes and ears in the office, which you can remotely control, whilst you are not in the office. These sort of devices mean that you can still connect with other workers, almost as if you were there in the room with them.

The head of one of Anybots QB robots – notice the webcam eyes and screen inbuilt into the head – such robots can improve the potential for remote working

You don’t necessarily need a QB robot to stay in communication with others though. Technologies like webcams, and VoIP mean that it is really easy to stay in contact, and in the loop, so you are just as up to date, as you would be, were you in the office.

Service Improvement Through Better Access

Technology has made it easier to work remotely, and it is often cheaper, but another advantage of teleworking, and a reason which I believe will be one which causes further growth in the industry, is the improvements in accessibility that teleworking offers.

In his recent article ‘Five changes in video conferencing for the next decade‘ Rashed wrote about how improvements in connectivity could improve the prospects for services like telemedicine. Being able to connect to people remotely, means that those who live/work in more remote areas, are more likely to be able to become connected.

Improvements in Productivity

Many studies have shown that working from home can actually boost productivity and reduce the time employees take off ill.

British Telecom claims that its teleworkers save it an average of £6,000 per year (per worker) due to the reduction in the costs of having to provide a workstation, the reduction in commuting costs, and through the increases in productivity. BT claims that its teleworkers are 20% more productive and take fewer sick days. This is probably due to the reduced stress associated with working at home, due to employees not needing to deal with the hassles of commuting, and the occasional hassles presented by co-workers, arguments and misunderstandings can cause stress!

In addition to this, the less time employees spend commuting, the more time they have to themselves, and the more time they can spend working. Say an employee spends an hour and a half commuting each day (two 45 minute journeys) then they could spend an  get an extra 45 minutes working, and get an extra 45 minutes to themselves.

In Summary

To conclude, working remotely is often a much cheaper option for both firms and employees, it has been made more viable thanks to technological improvements, it can improve the services that a firm can offer, and also improve the productivity of the workforce. These are some of the reasons, why I believe teleworking will become much more common in the future.
