The true story of an SMB attacked by hackers

2016Jan20_Security_CWhen big companies like Dropbox or Ashley Madison are hacked, the whole world hears about it. But how often do you hear about cyber attacks on the SMBs of the world? Probably not often, or never. Well, today, that’s all about to change. The NY Times recently ran an article telling the story of a small business, just like you, who suffered a major cyber attack. Here’s the story, and some ideas as to how to protect your business.

Last holiday season, Rokenbok Education, a small, California-based toy company of seven employees realized its worse nightmare. During the busiest time of the sales year, the files in their database had become unusable, infected with malware. The hackers used ransomware, a malware designed to hold a business’s data hostage, to encrypt their files and demanded a payment to make them usable again. However, instead of paying the ransom, Rokenbok restructured their key system. To do this it took four days. That’s four days of downtime, lost sales, and confused customers who likely lost confidence in the integrity of their company. Luckily this did not put Rokenbok Education out of business. But many SMBs aren’t so fortunate, and are forced to close after such a security debacle.

So why do security breaches like this happen to SMBs?

There are many reasons, but a common one is that small and medium-sized businesses often focus on profits over security. And really, it’s hard to blame them. When you’re small, you want to grow your organization as quickly as possible. And you likely think that because you’re small, no one is going to attack you. However, nowadays hackers are on to this way of thinking. They know that SMBs don’t focus as much on security, which make them a perfect target. In fact, according to Timothy C. Francis, the enterprise lead for Cyber Insurance at Travelers, 60 percent of all online attacks in 2014 targeted SMBs.

So what can your business do to protect itself against online attacks? There are a range of options, but it’s best to start off with an audit of your current security system to see where the holes are. This audit should check areas of risk which include customer data, employee access, and assets such as servers, computers and all Internet-enable devices.

After that, an obvious thing to do is to strengthen your passwords. While this has been said thousands of times over, many SMB owners do not take heed. Clay Calvert, the director of security at the Virginia-based firm MetroStar Systems, notes that hackers analyze how we create passwords and use big data analytics to crack them. “They have databases of passwords,” Calvert said. The best way to create a strong password is to make it long with a mix of characters. Password managers that encrypt your passwords can also help.

Aside from passwords, there are many other ways to boost your business’s security that include installing a firewall, keeping your antivirus up-to-date, and moving data over to the cloud (instead of storing it on company servers). Also, since many security attacks occur because an employee clicked on a malicious website or link, training your employees is a smart move. A good way to start this training is to create an employee manual that includes security guidelines they must follow. For ongoing training, you can keep them up-to-date on the latest security threats through email updates and regular meetings. Once you feel confident that your employees are up-to-speed and your security practices are updated, you can try hiring ethical hackers to test your systems and try to break through your security. This will let you know if there are any security holes you missed.

Calling in a security specialist

However, if all of this sounds far too much to bother with, consider outsourcing your security to a service provider that specializes in digital security. This can oftentimes save valuable time and money in the long run. Best of all, this can provide peace of mind, knowing that you have a security specialist watching over your business.

If you’re feeling overwhelmed and unsure where to start with your business’s security, we’re happy to help perform a thorough audit and provide you the digital security solution you need to keep your business protected. Security worries don’t have to keep you up at night, and we can help you implement the measures that will protect your business from disastrous security problems.

Chimera ransomware’s scary tactics

Female hand giving a bribe to businessman - closeup shotThe threat of being infected by malicious software is part and parcel of spending time on the internet, and no sooner have the antivirus and security software programs released an update or new patch than cyber criminals are scrambling for ways to circumvent them. In addition, as end users become savvier to the tricks and scams used to steal our data, money or identities, new tactics are employed to try and fool us. And that includes Chimera, a new strain of ransomware which has recently been uncovered.

Business is booming in the world of cyber crime, and scammers, extortionists, phishers and hackers are constantly on the lookout for new ways to exploit our fears and naivety in order to boost their bank accounts, steal our data, or simply cause us mayhem for their own twisted pleasure. One of worst types of malware for playing with our emotions – and therefore increasing the likelihood of us capitulating to its demands – is ransomware. If you don’t know how this program works, read on for an introduction.

If your computer has been infected by ransomware, the first sign that something is wrong is normally discovering that you are unable to open one or more of your files. That’s because the malware encrypts them, rendering them completely inaccessible. The next thing you see will be a ‘ransom note’, either in the form of an email or a notice that appears directly on your screen. You will be told that if you want to see your files again you will need to pay a sum of money. After making payment you will (allegedly) be sent a code that will allow you to decrypt your files.

Some types of ransomware up the fear factor even further by pretending that the FBI, CIA or other national law enforcement or government agency is behind the ‘kidnapping’. You will be told that your files are being held hostage because you have downloaded pirated software or files, or visited an illegal or illicit website – such as those depicting extreme pornography or threatening national security. Regardless of whether or not you are guilty of any of the above – be it a visit to an x-rated website, or downloading a pirated copy of the latest episode of The Walking Dead, your first instinct is probably to panic. The thought of no longer having access to any of our information, files or data is enough to make most of us break out into a cold sweat. If you haven’t backed up, everything from your vacation pictures to your company’s data could be lost for good.

The problem for ransomware creators, however, is that many users have wisened up to their tactics, and are refusing to pay, instead calling in an IT specialist to try and restore their encrypted files. This has left cyber criminals needing to find a way to boost ‘trade’. And that is where Chimera comes in. Christened by the Anti-Botnet Advisory Centre – a part of Germany’s Association of the Internet Industry – unlike previous forms of ransomware, which were indiscriminate when choosing their victims, this latest threat primarily targets businesses.

An employee will receive an email, purporting to be an application for a job within your firm, or some kind of corporate deal. This email will include a link ostensibly to the applicant’s resume or to details of the offer, but will in fact go to an infected file stored in Dropbox. Chimera then infects the user’s computer and encrypts any local files. Once the PC has been rebooted, the ransom note will be displayed on the desktop. Payment is usually set at around $680 USD, which must be paid in Bitcoins. And in order to further scare the victim into paying, the note will also state that failure to make payment will result in the user’s files being published online.

If there is a slight silver lining to the Chimera cloud, it is that the Anti-Botnet Advisory Centre has not found any proof that files have been published – at least not yet. In fact, it is still unknown whether the ransomware does actually take the encrypted files or if it is just an empty threat. Regardless, it is still a threat which could easily convince many users to pay the ransom. And should Chimera make good on its threats, the ramifications for a business are huge – and that’s without taking into consideration the nightmare of having your files encrypted in the first place. With Chimera targeting businesses of all sizes, and random employees within the business at that, isn’t it time you took another good look at your organization’s security posture?

Contact us today and talk to one of our security experts. We’ll be more than happy to help ensure that your small or medium-sized business isn’t taken hostage by Chimera or any other type of ransomware.

Twitter alerts users to cyber attacks

Security_Dec18_CSomething known as “state-sponsored cyber attacks” may not be something you have heard of until now. But with both Facebook and Google viewing the problem as serious enough to warn their users about, it seems this is an issue that could be here to stay. And now with Twitter also recently taking steps to alert their users about possible account hacking attempts, this may well be something that many of us should be concerned about.

But how at risk actually are you from a state-sponsored cyber attack? Is your small or medium-sized business in danger of being targeted? And who is behind these hacking attempts? Well, going by the warnings recently issued by Twitter, reports so far suggest that people, companies or organizations connected to internet security and freedom of speech are currently most likely to be at risk. But ‘currently’ is somewhat ambiguous, for in the world of cybercrime things can happen at lightning speed, and someone who is a target today might be deemed out of danger tomorrow – and vice versa.

As always, the best form of protection is to be forewarned, and you can only do that by learning as much as you can about the latest threats, scams and attacks. If you are a Twitter user, be it personal or for business use, you may be wondering why you have not yet heard of these alerts. That’s because Twitter’s messages were only sent to a small, and mostly rather niche, group of users. The email informed these users that Twitter was contacting them as a precaution due to their accounts “possibly” having been hacked by the state-sponsored actors. The email also stated that they believed that the actors may (or may not) be associated with a government, and that those involved had been looking to obtain personal information such as email addresses, phone numbers and/or IP addresses. So far, so vague!

Twitter then goes on to say that, although they have no evidence that any accounts were compromised or any data was stolen, they are actively investigating. They also lamented the fact that they wished they could say more…but that they had no additional information at that time. The email goes on to attempt to reassure users that their accounts may not have been an intentional target, but admits that if a user tweets under a pseudonym, that Twitter understands they may have cause for concern. But with so many Twitter users tweeting under a different name – and perfectly innocently, at that – what’s the real cause for concern here?

The issue lies with the type of accounts that were mostly targeted. The majority of these belonged to people or organizations connected to, or concerned with, cyber security. In fact, Twitter even offered some handy advice on protecting your online identity, suggesting users read up on the subject at the Tor Project website. Somewhat coincidentally, one of the victims of the attempted Twitter account hack is an activist and writer who currently educates journalists about security and privacy – and who used to work for the Tor Project. Another is a Canada-based not-for-profit organization involved with freedom of speech, privacy and security issues, and one of its founders is a contractor for the Tor Project.

Other Twitter users who received the email are also involved in some way or another in cyber security, albeit as self-described “security researchers” or simply by way of following or engaging with the online security community. This might lead you to the conclusion that, if you’re not in the business of security and instead keep your tweets to sport, entertainment, and the latest must-have gadgets, you are not at risk. But we urge you not to be so hasty. That’s because, within that small group of people who were contacted by Twitter, a large proportion of them had nothing to do with activism, freedom of speech, calls for greater privacy, or anything of the sort.

This means that, far from brushing this latest round of cyber threats under the carpet, individuals and business owners – whatever industry they are in – do have at least some cause for concern. As yet Twitter has not released details of the state the “actors” are sponsored by, so for now we are none the wiser as to whether it’s a homegrown issue or one from further afar – say North Korea or China.

What does all this mean for you as a business owner or manager? It means that you should be taking your online security more seriously than ever. It’s no longer just your network that is at risk; now simply having an account on a social media site such as Facebook or Twitter could be providing less-than-desirable third parties with the portal they need to access your company’s private information.

If you’d like to know how to ensure the online safety of your organization, give us a call today. Our experts have experience in everything from securing your computer network to increasing safety when it comes to sending out those all-important tweets!

How Google overcomes secure browsing issues

Security_Dec17_CIt’s safe to say that malware attacks, phishing scams, and social media engineering practices are going nowhere fast. That means that, whether you are a home user or the owner or manager of a small or medium-sized business, if you choose to ignore safer online security practices you are putting your identity and the security of your company at serious risk. But what are big providers like Google doing to stop cyber threats in their tracks? After all, surely the onus is on them to provide a service that is secure as it possibly can be?

With more than one billion people using Google’s search engine on their desktops, and over a billion more accessing it through mobile devices, it is clear that security is – or should be – paramount. Google already claims to protect desktop users with its Safe Browsing service, but what about its mobile users?

With cyber threats ranging from the annoying, such as adware, to the unsavory – hello spyware – and the downright terrifying (ransomware, we’re looking at you), mobile device users are increasingly demanding to know that they are being adequately protected when using Google’s products, tools and services. So in order to protect the mind-bogglingly large number of people who are using Google on their smartphones, laptops, notebooks and tablets, Google recently unveiled plans to extend its Safe Browsing service to mobile users – or at least to who are using Chrome on an Android device.

Whether you regard this as a blatant ploy to get users to switch to Android is something we’ll let you decide for yourself, but the fact is that Google is taking steps to protect its users. Back in August 2014, the company bolstered its Safe Browsing warnings with messages alerting users to unwanted software programs trying to sneak onto their computers by attaching themselves without warning to a legitimate download. In addition, both the Android platform and the Google Play Store have security measures in place to weed out potentially dangerous apps.

However, not every cyber security threat comes from an app or installation so, while Google is doing the right thing by guarding against threats in these areas, there are other issues that require a different means of protection. Enter social engineering, and phishing in particular, which can cause untold harm – such as data or identity theft – to a business or individual.

In order to protect against social engineering, an up-to-date list of malicious websites needs to be stored upon the device – this enables Google to send an alert to the user before they get ambushed. But there are problems with this which Google has had to overcome, not least of which is how to keep the list updated in the face of new threats. Compounding this issue further are factors that are unique to mobile browsing: mobile data speeds can be slow and connectivity patchy, depending where the user is. A fast, stable connection is crucial when the timing of an alert is paramount. Not only that, but using mobile data costs the end user money!

Bandwidth (and battery) limitations mean Google has had to find a way to ensure the data they send to users is as small as possible. Protecting their customers is crucial – but so too is not sapping battery life and data plans. Because this boils down to connectivity and speed factors, a device’s location is now taken into account. For example, if a known phishing scam is only affecting certain locations, only devices that are in that part of the world receive a warning.

Google also prioritizes data by sending information on a need-to-know basis – in other words, bigger threats take precedence over more minor issues. They have also designed the software to limit network traffic, and to be as light as possible on memory and processor usage.

Since its announcement in early December, Google is now protecting all Chrome users on Android devices as default, making Safe Browsing part of their Play services from Version 8.1 onwards. Chrome Version 46 is also the first app to initiate Safe Browsing.

How do you know whether you are protected by Safe Browsing mode? Go to your settings in Chrome, and check your Privacy menu. How do you know if your small or medium-sized business stands the best chance of survival in the face of a cyber attack or phishing scam? Talk to us today and we’ll be more than happy to share our up-to-date knowledge with you.
