We’re frequently bombarded with requests to remember and reset passwords, but this taxing memory drain is causing security fatigue and making us less safe.

And this security fatigue is causing PC users to take shortcuts with their cyber security e.g. using the same password time and time again across all the online platforms you have to sign in to. Whilst this is a simple solution, it’s also incredibly unsafe as it’s compromising the security of almost all your data.

As this is a security threat which is entirely rooted in the user base, it’s one that’s relatively simple to treat, but in practice it’s one that’s overlooked. Let’s take a look at exactly what’s happening and how you can tackle it.

What Is Security Fatigue?

It seems that not an hour goes by where we’re not prompted to change a password, verify an incoming connection or download a security patch. And this can be a time consuming affair when we’re in the middle of something important, so many PC users begin to experience security fatigue and go for the easy option: ignore everything.

Unfortunately, this puts you at a high risk of susceptibility to hackers. If we go back to our password example, from earlier, we can begin to understand the risks of security fatigue – you won’t just lose one account’s data, but all your data period. And, obviously, overcoming this security fatigue and creating multiple passwords is going to contribute heavily towards damage limitation.

Tackling Security Fatigue

The use of computers in our daily business lives has rapidly expanded in the last 15 years, so the need for security has rapidly increased accordingly. Whereas you once needed just one password to log on your PC, you now probably have to have a whole host of passwords for accessing databases, online portals and emails etc.

As a result there’s no going back to the days of single passwords – we now require around 25 daily to cover all our needs – so we need to learn how we can adapt to this new landscape. And there’s no use dismissing the threat of hackers targeting your data simply because it doesn’t relate to anything important. If a hacker can find even the most insignificant entry point into your network they’ve got a huge head start on causing damage within.

Organizations, therefore, need to work towards lightening the load on their user’s security requirements, but at the same time keep their data secure. This is not an easy problem to solve, but by employing the services of security companies you can gain professional insights on the best way to create a simple security system which reduces the difficulty of decision making and prevents security fatigue setting in.

Taking Down the Internet: The Attack on Dyn

Even the biggest firms are failing to combat cyber-attacks as a recent DDoS case has revealed; if the big firms are struggling, what does this mean for you?

Well, what’s most interesting is that this distributed denial of service (DDoS) targeted some major players of the online world such as Twitter and PayPal. As you would imagine, these firms spend millions of dollars on cyber-security, but they were still successfully hacked and found their services severely disrupted.

It’s incidents such as this which highlight just how frail security defenses can be when confronted by a formidable foe. To help you understand how the power is shifting out there, I’m going to take a look at the current landscape.

The Dyn Inc DDoS Attack

The DDoS attack we’ve been focusing on was aimed at the cloud based online infrastructure company Dyn Inc; basically, these guys form the server backbone for brands such as Twitter, PayPal and Netflix.

And it was this backbone which was targeted by hackers through a phenomenal botnet capable of transmitting 1.2 trillion (that’s 12 zeros!) bits worth of data at Dyn Inc every second. Understandably, these huge amounts of data soon brought severe data outages and this is why sites like Twitter suddenly disappeared from the web.

Fortunately, this huge influx of data eventually stopped, but it was an attack of such magnitude that it’s left the security industry very concerned.

Why Are Attacks Getting More Prolific?

DDoS attacks have steadily been ramping up their power in recent months, so it seems as though there’s a concerted effort amongst hackers to outdo each other. This is a dangerous scenario and is leading us down a path towards a world of super powerful hackers.

These hackers are also being helped in the upsurge in popularity of the ‘internet of things’. Thanks to the huge proliferation of internet ready devices (smart TVs, security cameras and even heating systems) there are now more entry points to your core network than ever before.

In fact, a recent mock-up of a wireless toaster demonstrated just how quickly hackers can find access points to networks. In this example, everything was securely set up to prevent any damage occurring, but not all Wi-Fi ready devices are this secure. It’s predicted that any device which can be accessed by the public is potentially vulnerable.

And it’s in sharp contrast to, for example, a decade ago when hackers only had the limited choice of attacking PCs, but the playing field is now becoming wider and wider with the internet of things. Matters aren’t helped by the increase in popularity of ‘cyber-crime as a service’ which allows anyone to buy hacking tools or services from the dark web and carry out crude cyber-attacks.

Protecting Yourself

Hackers are becoming more and more sophisticated, so it’s crucial that you conduct a thorough analysis of your security precautions on an ongoing basis. It’s paramount, in particular, to keep a close eye on any devices which connect to the internet as they may need specialist attention to make secure.

When it comes to preventing DDoS attacks, it’s a little harder as they’re difficult to prevent. Sure, you can have ‘bad traffic’ routed elsewhere, but this is a very costly service. And this is why the future for cyber-security is a little uncertain and means hackers are increasing their chances of successfully completing a hack.

Backdoor Attacks Pose a Real Headache for Cyber Security

Backdoors are a point of access which can be illegally installed to give hackers free and easy network access; they’re also very difficult to detect.

Unfortunately, for all computer users, backdoor hacks are a form of cyber-attack which is on the rise. And what’s particularly galling for businesses is that they’re becoming harder and harder to combat.

I’ve previously covered variants of backdoor attacks – such as the GlassRAT Trojan – but it’s time I took a closer look at how these backdoors operate.

What is a Backdoor Attack?

Gaining remote access to a computer network is a hacker’s dream, so anything that makes this a possibility will be pursued by hackers; a backdoor to your network is the most straightforward way of achieving this.

It literally is a ‘backdoor’ which hackers can use to come and go as they please without leaving any signs of forcing an entry. And with free rein to access your network, a hacker will seriously compromise the safety of your data and all your systems.

How Do Backdoor Attacks Take Place?

What’s particularly tricky about backdoor attacks is the number of different strategies they employ to breach your defenses:

  • Software Exploits – Many pieces of software have backdoors built into them that only the developer is aware of. Sometimes this can be to help aid in maintenance, but there have also been reports of government agencies insisting ‘secret backdoors’ are installed to aid security. However, no matter how secret these backdoors are, there’s always the chance a hacker will discover them.
  • Malware – One of the most common methods of establishing a backdoor is through malware which first breaches the network before downloading code to setup a backdoor. As we’ve learned previously, malware can come in many forms such as email attachments and phishing.

Both these methods are troubling as they can take the form of a zero day exploit, so firewalls and anti-malware software are oblivious to these new security threats which leads to a period where the attack simply isn’t detected.

Secondly, the backdoor establishes the hacker with seemingly legitimate credentials and this fails to create any suspicion around the connections being made into your network, so they’re not easy to pick up and gives the hacker plenty of time to run riot.

How to Defend Against Backdoors

Although backdoors are tricky attacks that are difficult to counter, you can still protect your network by taking the following measures:

  • Don’t Forget The Old Methods – Firewalls and anti-malware software still have a place and can detect a high proportion of backdoor activity e.g unauthorized incoming traffic. Therefore, it’s not quite time to dispose of these quite yet otherwise you run the risk of a simple and quick hack taking place.

Cyber Crime as a Service – A New Threat

Computer crime concept

The latest evolution in hacking is here and it’s known as Cybercrime as a Service (CaaS) and it promises to create faster, more powerful hacks, but how?

Well, many people have a need to carry out hacking operations, but don’t have the technical skills to design or even launch these types of cyber-attacks. Therefore, there’s a niche in the market for those who do know how to design a piece of malware to monetize their skills. And this is what the foundations of CaaS are built upon – money and cybercrime.

How exactly does it work, though? And what does it mean for the future of cyber security?

What is CaaS?

Hacking has rarely been referred to as an ‘industry’ despite a few individuals willing to carry out cyber-attacks in exchange for money. However, with CaaS, hacking appears to be turning into an industry which means big bucks and nightmares for computer owners all over the world.

Say, for example, a disgruntled ex-employee wants to sabotage their previous employer’s website to cause disruption to their activities. Now, it’s highly unlikely that this employee would be skilled in the world of cyber-crime, so what would they do? Well, previously they would have tried reading a few online articles about hacking and then given up when they realized how difficult it was.

With the advent of CaaS, though, this ex-employee could easily purchase the software or the execution services of a skilled hacker. Naturally, this is a highly illegal act for both parties, so the resources for these types of services tend to be hidden on the dark web to lower the chances of identification.

Consumers can expect to find malware kits, access to infected computers and even botnet rentals which allow the initiation of Denial of Service attacks. Therefore, it’s somewhat of an Aladdin’s Cave for someone who is looking for quick, easy access to cybercrime e.g. exploit kits can be purchased for just $50 per day and, believe me, they can cause a lot of damage in one day.

What Does CaaS Mean for Hacking?

CaaS is making hacking much more accessible for the average computer user whereas, before, it was purely the preserve of those who had the skill to design malicious software and carry out sophisticated attacks. This means that we can expect to see an increase in attacks in the future, so safeguarding your networks is more important than ever.

One of the most troubling aspects of CaaS, though, is that when a service becomes a business it drives competition amongst the vendors. And this means that those hackers who are designing exploit kits and various other hacking tools are going to have to up their game to remain in the market.

Therefore, we’re going to see a rapid evolution in the capabilities of hacking tools, so expect faster and more devastating attacks which are harder to stop. In order to protect yourself from these enhanced attacks you’re going to have to ensure that your cyber security protocols enhance visibility of such attacks and prevent them taking hold of your systems.

Malware is Evolving and Getting Harder to Stop

We like to think that once a cyber-attack takes place that a solution will be found. However, malware is evolving and becoming harder and harder to stop.

In Q1 2016, Kaspersky prevented just over 228 million malware attacks and this is a   figure which has been increasingly rapidly for the last few years. In fact, several years ago, it would have been unlikely to see pushed 228 million malware attacks in an entire year.

Malware, therefore, remains big business for hackers so, naturally, they’re constantly looking to upgrade their weaponry to beat the firewalls and antivirus software we rely on. And it’s a digital arms race which the cyber security experts are struggling to keep up with.

Let’s take a look at why malware is getting harder to stop.

Ransomware Arrives

One of the most reported evolutions in the malware landscape has been the rise in ransomware attacks such as Locky.

Ransomware is a form of malware which encrypts users’ files and then demands a ransom to decrypt them. Being a relatively new form of malware, knowledge regarding their build and execution capabilities is somewhat limited, so this is making them particularly difficult to combat.

What’s also crucial to the success of ransomware is that the majority of attacks are routed through anonymous Tor servers which mask the attacker’s true IP address. This means that identifying the hackers becomes very difficult and they’re able to continue operating impeded and improve their malware. And this evolution of existing ransomware is best demonstrated by the Locky Trojan which began as a .DOC file, but is now being identified as a .ZIP archive in order to evade detection.

Targeted Attacks

Malware has, traditionally, followed the same execution regardless of which network it has been deployed upon. However, hacking groups such as Poseidon are now ensuring that their attacks are, after the standard breach, able to customize the attack depending upon the network.

Poseidon maps their victims’ networks and harvests all the available credentials to ensure they can gain the maximum privileges on the network. And the reason for this customized attack is because Poseidon is actively hunting the computer which operates as the local Windows domain controller. If the hackers are able to take control of this computer then they will have free rein over the entire network.

It’s this type of attack which is a cyber-security firm’s worst nightmare as it involves extensive research into the intricacies of individual networks. This is very time consuming and underlines how hackers are actively looking to make themselves more powerful.

Long Term Evolution

One of the biggest problems with Malware is that certain strains are constantly evolving into new strains. The best example of this is the Adwind RAT (remote access tool) which first appeared in 2012 as a tool for online spying.

Originally debuting under the name Frutas, it evolved into Adwind, Unrecom, AlienSpy and JSocket over the next three years. Starting off as a Spanish language piece of software, it soon received an English language interface which allowed it to spread worldwide.

All these changes have allowed the Adwind RAT to enjoy a long career and cause so many cyber-attacks. By actively changing its exterior appearance and name, it has fooled firewalls and antivirus software to leave security experts scratching their heads.
