Ransomware to begin self-propagation

One of the biggest fears security experts have may be coming true: self-replicating ransomware. Viruses that have the ability to copy and spread themselves to new systems are nothing new, but until now ransomware attacks have been targeted campaigns. The best way to protect your network from a security threat is to understand it, here’s everything you need to know about this latest development.

Ransomware, the malware that locks up infected systems and demands payment to return access to users, has been steadily increasing its infection rate over the course of this year. Enigma Software reported that, “After staying steady for the last six months of 2015, ransomware detection has begun to climb; February saw a 19 percent increase over January, while March had almost a 10 percent increase over February. Then, in April, infections more than doubled.”

And as if that wasn’t frightening enough, Microsoft announced last week that a recently detected ransomware software was found copying itself onto USB and network drives. The ransomware, titled ZCryptor, disguises itself as either an Adobe Flash installer or a Microsoft Office file to trick users into opening it.

Once opened, it displays a prompt that says “There is no disk in the drive. Please insert a disk into drive D:”. If you see this after opening a suspicious file, it is most likely ZCryptor trying to distract you while it works in the background to add a registry key that buries itself deep in your system and begins to encrypt your files.

Although previous ransomware iterations like Alpha Ransomware had the ability to find and encrypt files on shared network drives, security experts believe this is the first time a ransomware variant has included self-replication via removable drives into its framework.

When it was first detected in May, Microsoft found ZCryptor singling out 88 different file types for encryption. However, later on a security expert analyzed the ransomware and found 121 targeted file types — inferring that creators of the malware were continuing to develop its source code.

It’s commonplace for ransomware to demand payment to be made in Bitcoins as they’re an almost totally untraceable online currency. ZCryptor is no different, demanding 1.2 Bitcoins (500 USD) unless payment is more than four days after infection — then it increases to five Bitcoins (2,700 USD).

Compared to other more complex security threats, ransomware is still relatively easy to avoid. Always verify the source of email attachments and website downloads before opening files, disable macros in Microsoft Office programs, maintain regular backups and update your security software.

Still concerned about security at your SMB? It doesn’t have to be as difficult and draining as you may think. Contact us today for advice on keeping your network protected around the clock.

Can Your Business Survive A Disaster?

Disasters. They do happen — it’s only a matter of ‘when’. While most businesses acknowledge it, surveys show that only one in four companies worldwide have adequate protection in the event of a major disruption. We’re not talking about insurance here, but a Disaster Recovery (DR) plan that could save you thousands of dollars in losses and worse, a business closure. If you haven’t heard much about what DR is, this post will help you gain some insight about what it is and how it can affect the future of your business.

As we all know, unpredictability is a fact of life. The aftermath of Tropical Storm Bill in Texas and recent floods in South Carolina are a grim and unfortunate lesson for many overconfident business owners who think their companies are spared from the likelihood of cataclysmic weather, technological malfunctions, or human actions. A 2014 survey by the IT Disaster Recovery Preparedness (DRP) Council reveals just how many companies worldwide are at risk: 73 percent of SMBs are failing in terms of disaster readiness. What does this mean? It means that 3 out of 4 companies aren’t prepared to handle emergencies and save their businesses from a worse-case scenario.

If it’s not clear and compelling enough for a business owner like yourself to consider putting a well-conceived Disaster Recovery (DR) plan into place, perhaps it’s time to give it some thought. Doing so can save you years of business loss. Here is some useful information about what DR is all about and how it can ensure your business’s survival in the wake of unforeseen circumstances.

What is Disaster Recovery (DR)?

Disaster recovery is a plan for restoring and accessing your data in the event of a disaster that destroys part or all of a business’s resources. It is a key component involving many aspects of business operations that requires this information to function. The job of a DR plan is to ensure that whatever happens, your vital data can be recovered and mission-critical applications will be brought back online in the shortest possible time.

What kind of disasters are likely to happen?

Business disasters can either be natural, technological, or man-made. Natural types of disasters include floods, earthquakes, tornadoes, hurricanes, landslides, tsunamis, and even a pest infestation. On the other hand, technological and man-made disasters involve hazardous material spills, infrastructural or power failure, nuclear power plant meltdown or blast, chemical threat and biological weapons, cyber attacks, explosions, or acts of terrorism and civil unrest.

Why does your business need DR?

Regardless of industry or size, when an unforeseen event takes place and causes day-to-day operations to come to a halt, a company will need to recover as quickly as possible to ensure you will continue providing services to clients and customers. Downtime is one of the biggest IT expenses that any business can face. Based on 2015 disaster recovery statistics, downtime that lasts for one hour can cost small companies as much as $8,000, mid-size organizations $74,000, and $700,000 for large enterprises.

For SMBs particularly, any extended loss of productivity can lead to reduced cash flow through late invoicing, lost orders, increased labor costs as staff work extra hours to recover from the downtime, missed delivery dates, and so on. If major business disruptions are not anticipated and addressed today, it’s very possible that these negative consequences resulting from an unexpected disaster can have long-term implications that affect a company for years. By having a Disaster Recovery plan in place, a company can save itself from multiple risks including out of budget expenses, reputation loss, data loss, and the negative impact on clients and customers.

How do I create a DR strategy for my business?

Creating, implementing and maintaining a total business recovery plan is time-consuming but extremely important to ensure your business’s survival. Many organizations don’t have the time or resources to dedicate to this process. If you would like to protect your company from unexpected disasters but need further guidance and information on how to get started, give us a call and our experts will be happy to discuss Disaster Recovery options and solutions with you.

Chimera ransomware’s scary tactics

The 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.
