Hackers use browsers to get credit card info

January 27, 2017 admin Security 2017january27_security_c, chrome, credit card theft, hackers, safari, security

Does filling in web forms sap all your browsing energy? Do you find it especially taxing to shop or register online using a mobile device? Google’s Chrome alleviated this dilemma when it introduced the Autofill feature in 2011, which made filling in forms much faster and making credit card purchases online more convenient. Unfortunately, it didn’t take that long for cyberthieves to find a way to take advantage.

How do they do it?

By concealing other fields in a sign-up form, users are tricked into thinking they only have to fill out a few fields. The trickery at work is that upon auto-sign up, other fields, which could include your billing address, phone number, credit card number, cvv (the 3-digit code used to validate credit card transactions), and other sensitive information, are auto-filled with the user none the wiser.

This sinister trick is nothing new, but since there hasn’t been any countermeasure since it was first discovered, the threat it poses is worth emphasizing. Finnish whitehat hacker Viljami Kuosmanen recently brought to light how users of Chrome and Safari are particularly vulnerable, and he even came up with a demonstration of how this phishing technique is perpetrated. The technique is so sneaky, it’s enough to make one give up online shopping forever.

Using plugins and programs such as password managers is also fraught with the security risk, as having access to such a utility empowers cyberthieves to do more than just obtain your credit card info; it opens them up to a great amount of personal details.

Preventing an autofill-related theft

So what can you do to avoid falling prey?

Using Mozilla Firefox is one of the easiest available solutions. As of today, Mozilla hasn’t devised a mechanism that affords its users the same convenience that Chrome and Safari users enjoy with autofill. When filling web forms on Firefox, users still have to manually pre-fill each data field due to a lack of a multi-box autofill functionality – a blessing in disguise, given the potential for victimization in autofill-enabled browsers.

Another quick fix is disabling the autofill feature on your Chrome, Safari and Opera (for Apple mobile devices) browsers. This would mean that when filling out web forms, you’d have to manually type responses for every field again, but at least you’d be more secure.

It’s not exactly the most sophisticated form of online data and identity theft, but complacency can result in being victimized by cyber swindlers. Take the first step in ensuring your systems’ safety by getting in touch with our security experts today.

Ransomware to begin self-propagation

June 9, 2016 admin Security 0 Comments 2016june9_security_c, cyber criminals, data loss, hackers, ransomware, security, worm

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.

Understand these 4 types of hackers

April 28, 2016 admin Security 0 Comments 2016apr28_security_c, attack, cyber criminal, hackers, hacktivist, insider, motives, script kiddie, security

2016Apr28_Security_C Why do hackers attack? Is it for money, notoriety, or political reasons? Many business owners never ask these questions, and instead only think about the means of how a cyber attack takes place. But knowing the motive behind a hacker’s attack can help you understand whether or not you’re a target and what data you need to protect. So let’s take a closer look at 4 different types of hackers and their motives.

Script Kiddies

When it comes to skill level, Script Kiddies are at the bottom of the totem pole and often use scripts or other automated tools they did not write themselves – hence the name. With only an elementary level of technical knowhow, Script Kiddies usually don’t cause much damage…usually. The Script Kiddy virus known as the Love Bug which sent out an email with the subject-line “I LOVE YOU” fooled millions of people, including some in the Pentagon, in the early 2000’s. The virus reportedly caused around 10 billion in lost productivity and digital damage.

So who is a Script Kiddie? Most of the time they’re simply bored youth looking for a thrill or notoriety. Many never evolve into a full-time hacker, and instead just use their skills as a hobby. Oddly enough, many Script Kiddies find a career later on working in the security industry.

Hacktivist

If you’ve heard of Anonymous, LulzSec or AntiSec, then you’re familiar with Hacktivists. These groups are made up of members of varying skill levels, all the way from Script Kiddies to some of the most talented hackers in the world. Their mission is largely politically motivated as they aim to embarrass their targets or disrupt their operations, whether that be a business or government body. Two of the most common ways they attack their target are by stealing sensitive information and exposing it or denial of service (DDoS) where a server is overloaded till it finally crashes.

As a small or medium-sized business owner you are not necessarily immune to Hacktivist disruption. If your business or a company you’re associated/partnered with participates or provides services that can be seen as unethical, such as Ashley Madison (who fell victim of a major Hacktivist attack last year), then you too may be targeted by Hacktivists.

Cyber Criminals

Often talked about in the media and well-known by most SMBs, cyber criminals are after one thing: money. Their targets run the gamut, including everyone from individuals to small businesses to large enterprises and banks. But what do these targets usually have in common? They either have a very valuable resource to steal or their security is easy to exploit…or a combination of both of these. Cyber criminals can attack in a number of ways including using social engineering to trick users into providing sensitive information, infecting an organization/individual with ransomware or another form or malware, or exploiting weaknesses in a network.

Insiders

Perhaps the scariest type of hackers are the ones that lurk within your own organization. Insiders are made up of disgruntled employees, whistleblowers or contractors. Oftentimes their mission is payback; they want to right a wrong they believe a company has perpetrated toward them, so they’ll steal sensitive documents or try to disrupt the organization somehow. Edward Snowden is a prime example of an insider who hacked his own organization – the US government.

Now that you know what motivates your enemy, you’ll hopefully have a bit of an idea as to whether or not you’re a target. To learn more about how to secure your business from these types of hackers, get in touch with our experts today.

4 BYOD security risks you should address

April 13, 2016 admin Security 0 Comments 2016apr13_security_c, Bring Your Own Device, BYOD, data leak, hackers, lost devices, malware, security risks

2016Apr13_Security_C In the 21st century, personal computing is with us wherever we go. This is all thanks to the proliferation of mobile devices such as smartphones and tablets. These devices allow us to take work home with us. And, with bring your own device (BYOD) strategy, businesses have never been so productive. However, BYOD poses a number of security risks if you’re not careful. What are these problems? How are they caused? Here are some BYOD security risks you should know before implementing it in your business.

Data leakage

The biggest reason why businesses are weary of implementing a BYOD strategy is because it can potentially leave the company’s system vulnerable to data breaches. Personal devices are not part of your business’s IT infrastructure, which means that these devices are not protected by company firewalls and systems. There is also a chance that an employee will take work with them, where they are not using the same encrypted servers that your company is using, leaving your system vulnerable to inherent security risks.

Lost devices

Another risk your company has to deal with, is the possibility of your employees losing their personal devices. When devices with sensitive business information are lost, there is a chance that this could end up falling into the wrong hands. Additionally, if an employee forgets to use a four digit PIN code to lock their smartphone or tablet, anyone can gain unauthorized access to valuable company data stored on that particular device. Therefore, your company should consider countermeasures for lost devices like completely wiping the device of information as soon as an employee reports a missing or stolen phone.

Hackers can infiltrate your system

Personal devices tend to lack adequate data encryption to keep people from snooping. This along with the fact that your employees might not have updated their devices can allow hackers to infiltrate your IT infrastructure.

Connecting to open Wifi spots makes your company more susceptible to hackers. Open wireless points in public places can put device owners at risk because there is a chance that hackers may have created that hotspot to trick people into connecting. Once the device owner has connected, attackers can simply surveil web activity and gain access to your company’s accounts.

Vulnerable to malware

Viruses are also a big problem when implementing BYOD strategies into your business. Using personal devices means your employees can access whatever sites or download any mobile apps that your business would normally restrict to protect your system.

Jailbreaking or rooting a device also puts your systems at risk because it removes limitations imposed by the manufacturer to keep the mobile software updated and protected against external threats. It’s best to understand that as your employees have the freedom to choose whatever device they want to work with, the process of keeping track of vulnerabilities and updates is considerably harder. So if you’re thinking about implementing BYOD strategies to your business, prepare your IT department for an array of potential malware attacks on different devices.

So you might be thinking that it would probably be best to just avoid implementing a BYOD strategy in the first place. However, BYOD will help your business grow and adapt to the modern workplace, and should not be dismissed as a legitimate IT solution. It’s just important to educate your company about these risks so that problems won’t occur for your business down the line.

If you need some help implementing IT security solutions for your company, or if you have any concerns regarding IT, give us a call.

The true story of an SMB attacked by hackers

January 25, 2016 admin Security 0 Comments 2016jan20_security_c, audit, cyber-attacks, hackers, password, QS_3, security, small business, smb

When 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.
