The importance of installing updates and patches should never be underestimated. However, did you know that even these are not 100% secure?

Microsoft knows a thing or two about computers, but this doesn’t mean they are immune from mistakes and flaws. Accordingly, they regularly release patches and updates to address any vulnerabilities in their software.  A recent investigation, though, has discovered that these updates aren’t quite the safeguard consumers would expect. And, when you consider the amount of applications that Microsoft bundle with their systems, this is a matter of major concern.

Given the number of patches you are prompted to install each and every week, it’s important to understand what has happened on this occasion.

A Vulnerable Patch

The initial vulnerability in question relates to a flaw which was discovered in Windows printing services. Your first thought may be that printers are far from a security risk, but this couldn’t be further from the truth. If a device or application has any form of access to your network then it needs strong defenses. And this is why Microsoft was keen to patch a vulnerability which offered hackers a route into PC networks through print spooler software. This patch was issued in May and Microsoft believed this was the end of the story. But this story was due to run a little longer.

Researchers discovered that the impact of this initial patch could be negated by simply bypassing it. By modifying .SHD files (better known as Shadow), the researchers were able to add them into the spooler folder. This particular type of folder allows commands to be sent between a PC and a printer. Usually this is the preserve of printing documents, but the modified Shadow files allowed the researchers to send all manner of commands. It’s a scenario which had the potential to give hackers full access to a network.

How Can You Defend Against Weak Patches?

The vulnerability in question is no longer in present in systems which have since been updated, but it paints a worrying picture for PC users. If you are unable to rely on patches to give you full protection then what hope do you have?

First of all, you must, no matter what, always install all security patches. They are a crucial aspect of security and are all programmed with an objective of preventing an attack. This printer spooler fiasco demonstrates they are not perfect, but the majority are capable of fulfilling their aims. Nonetheless, being overcautious with IT security is always a good idea. Therefore, make sure you follow these simple steps:

Government Websites Compromised in Armenia

You would like to think that governments know a thing or two about cyber security. But a recent hack in Armenia has proved otherwise.

European security experts ESET have confirmed that numerous websites belonging to the Armenian government have been targeted and compromised by hackers.   The compromised websites have been infected with malware and pose a nasty security risk to visitors. It’s suspected that the hackers behind this attack are Turla, a Russian hacking group.

We’ve discussed malicious websites before, but this latest attack is a little different. Therefore, it’s crucial that you understand the unique methods behind the infection.

What’s the Story?

The suspected hackers have targeted several websites that come under the control of the Armenian government, but the same fingerprints have also been found on a few non-government websites. Regardless of which website is infected, the methods employed are the same. However, where this attack differs from normal is its selective nature. Rather than attacking every visitor that accesses the infected websites, the malware only targets high-ranking visitors. So, for example, a civilian visitor is likely to remain uninfected, but a government official will not be so lucky.

It’s intriguing that the malware is only interested in high-ranking officials and indicates that there could be a political angle to the attack. Speculation aside, what is known for certain is how the attack unfolds. Once a visitor has been established as ‘high-value’ a command-and-control server generates a malicious JavaScript code. This code is used to deliver a popup window prompting the user to download a Flash update. But while this does, in fact, install a genuine version of Flash, it also contains PyFlash. And this backdoor application allows hackers to gain full access to the infected PC.

How Do You Protect Yourself?

Naturally, the security risk of compromised government PCs is considered high. And, while it is unlikely to affect smaller organizations at present, the selective nature of the attack is troubling. Therefore, it’s important that you safeguard your business against similar attacks. This can be achieved by following these best practices:

  • Use Website Filters: One of the best ways to protect your organization from infected websites is by integrating website filters into your IT setup. These filters are backed up by huge databases, which are regularly updated, and will prevent your users from accessing websites considered a security risk. 
  • Prevent Software Installation: The majority of applications that your employees will want to install are likely to be genuine and safe. But, as with fake Flash updates, this is not always the case. And this is why it makes sense to enforce a complete blanket ban on unauthorized installs. Accordingly, any install requests should be submitted to an IT professional who can evaluate the risk of each proposition.
  • Block Popup Adverts: It’s rare that any PC user welcomes the appearance of a popup advert. And, with the risk of malicious popups so prevalent, it’s the last thing that an IT professional wants to see as well. Therefore, it makes sense to minimize this risk by installing a popup blocker. Not only will this reduce the risk of malware being installed, but it will also provide your PC users with an enhanced experience.

WordPress is a popular platform for building websites, but this popularity has made it a target for hackers. And it’s now being used to launch hacks.

It’s estimated that around 75 million websites use WordPress as the backbone for their content. But not even the largest and most profitable tech companies are immune from hacking. Vulnerabilities are present in almost every piece of software ever designed. And when these vulnerabilities are discovered they will be exploited almost instantly by hackers. WordPress has fallen foul of this all too common scenario and, as a result, 100,000 web users have felt the attentions of these hackers.

Due to the ubiquity of WordPress websites it’s likely that your organization engages with them on a daily basis. It may even be that your organization’s website is hosted through WordPress. Either way, the threat presented is one you want to avoid, so let’s take a look at it.

How were the WordPress Sites Compromised?

Security experts Zscaler were the first people to identify that WordPress sites had been compromised. The nature of the hack is sophisticated, but relatively simple to pull off. After discovering a vulnerability in the ‘theme’ plugin, which is included in WordPress sites, the hackers were able to infect the sites with malicious scripts. These scripts were a form of code which redirected visitors to a Flash Player update alert. However, this urgent update was fake and all that would be downloaded was a malicious file.

The file in question was a Remote Access Trojan (RAT) which allowed remote access to the infected PC. And, with unrestrained access, the hackers were granted the opportunity to download and distribute malware as well as the chance to compromise data. But this isn’t the only way in which the malware infects PCs. Those using the Chrome browser faced an additional threat. Upon visiting the infected WordPress sites, Chrome users were prompted to download an update for the ‘PT Sans’ font. Again, this is a deceptive request and downloads the RAT.

Protecting Against the WordPress Hack

If you own a website which is built on the foundations of WordPress then it’s crucial that you update the associated content management system. This will instantly prevent your website from cultivating the hack and protect your visitors.

Unfortunately, it’s not always possible to tell when a website is using the WordPress system, so you should make sure you practice the following:

  • Scrutinize all Popups: The sheer range of dangerous popups means that they should always be scrutinized. Fake updates tend to stress an extreme urgency which is designed to tempt users into clicking them without checking. Instead, users need to take a second and consult with an IT professional to verify the update is genuine. 
  • Install Anti-Virus Software: It’s vital that your organization uses anti-virus software. Not only can it identify threats such as the WordPress hack, but they are regularly updated. This ensures that your organization is protected from all the latest threats.

The Titanium malware has been released into the wild and is already making plenty of headlines. But what’s the full story behind this backdoor malware?

New malware is released every day, but certain strains are more dangerous than others. And Titanium certainly stands out. It’s a piece of malware which is highly advanced in terms of technology and pushes the boundaries of hacking. Any organization which values its privacy and security, therefore, needs to be aware of Titanium. Hacking, after all, hits productivity hard and this is magnified when it’s an advanced hack.

So, to help protect your computer network and maintain productivity, we’re going to tell you all you need to know about the Titanium malware.

Where Did Titanium Come From?

A major hack needs a major ‘talent’ behind it and Titanium certainly satisfies this condition. The perpetrator is believed to be the hacking group known as Platinum. And, in the last few years, Platinum has gained notoriety for developing persistent threats in the Asia-Pacific area. Believed to be state-sponsored, Platinum has access to funds and technology to develop advanced hacking tools. And this is exactly what Titanium is.

Titanium spreads from PC to PC in a number of different ways:

  • Vulnerable intranets that have already been exploited by malware allow Titanium to get a foothold before infecting multiple workstations
  • Stealthily infecting Windows installation tasks and installing itself at the same time as legitimate software
  • Using a shellcode which is activated as part of the Windows logon process to ensure it’s active from startup

What Does Titanium Do?

Titanium is advanced malware and is able to infect computers in a number of different ways. It’s a combination which marks it out as a major threat, but what does Titanium actually do? Well, once it’s unleashed, it can do the following:

  • Read, send and delete any file contained within the infected PC
  • Edit configuration settings on the PC
  • Receive commands from a remote server

Titanium is particularly virulent due to its emphasis on stealth. The potential for mimicry within Titanium is strong as it can imitate a wide range of legitimate software. And it’s this skill for imitation which enhances Titanium’s ability to deceive and spread.

How Do You Tackle Titanium?

With its combination of multiple infection threats, ability to imitate and connection to remote servers, Titanium is a slice of malware you want to avoid. While it may be dangerous, it isn’t impossible to avoid. To keep one step ahead of Titanium make sure you practice the following:

  • Only install software that comes from a legitimate source e.g. purchased products and not illegal torrents
  • Make sure that network activity is continuously monitored to detect any unusual traffic
  • Double check all requests for software upgrades/firmware as these could easily be compromised by Titanium
  • Use a firewall at all times to help prevent unauthorized connections in and out of your network

Titanium may be very quiet at the moment – Kaspersky are yet to detect any current activity – but vigilance is recommended due to the forces behind it. By understanding the threat of Titanium you can ensure that your network is protected from yet another pressing threat.

Healthcare Data Leak: The Cloud is still Not Secure

Is the Cloud Secure?

Cloud computing is seen as the future of IT, but concerns regarding its security remain. A case in point is the Freedom Healthcare Staffing leak.

Compromised data is always associated with various dangers and problems, but these are always magnified when the data at risk is personal. And the employees of Freedom Healthcare Staffing (FHS) now know what this feels like. Around 957,000 private records were found to be readily available to anyone with an internet connection. These records included drug test records, recruitment details and in-house communications among more technical networking details. Not only were these records available, but the opportunity to edit and delete this data was also an option.

As more and more organizations are moving towards cloud computing, it’s important to understand where FHS went wrong. Let’s see what we can find out.

What Happened with FHS?

The unsecured data at FHS was compromised for one reason and one reason only: negligence. The folder, which contained close to a million records, was on a publicly available drive and had no password protection. Therefore any web browser, such as Chrome or Firefox, could access the data without providing any administration credentials. To make matters worse, the technical data that was visible in this folder provided an opportunity for hackers to delve even deeper into the FHS network. After a security researcher from Security Discovery analyzed this compromised database they informed FHS and all records were quickly secured.

 

Why is Cloud Security So Lax?

Cloud storage is a relatively recent development in IT, so it should come as no surprise that there are teething problems with the technology. But this doesn’t mean data should be left unsecured. Unfortunately, many consumers feel as though the responsibility of their data security should lie purely with the cloud provider. This approach, as FHS discovered, can be highly dangerous. You only have to take a look at the attacks taking place on cloud based data to understand why.

Organizations need to adopt a shared responsibility mindset in order to protect their cloud. And this should incorporate the following:

Enhanced knowledge will, with time, allow us to understand the limitations of cloud security, but as FHS discovered it’s important to take a proactive approach immediately.
