HP laptop users beware: keylogger found

December 20, 2017 admin Hardware 2017december20hardware_c, antivirus, cyber security, hardware, hp, keylogger, laptop, security, software

You might be entering credit card details on a website to purchase something online or filling in your personal information to subscribe to a service, thinking you’re safe behind the keyboard. And you probably are — if the computer you’re using doesn’t have a keylogger installed. But for HP laptop users, chances are they aren’t so lucky. Read on to see why.

What are keyloggers?

Keyloggers are hardware devices or software programs that record every key you press on your computer’s keyboard. Most keyloggers can also capture screenshots and send them to a remote computer where someone is waiting to see what you’re up to.

And why does this matter? Because hackers can steal your usernames and passwords, keep track of the messages you send via instant messaging apps or emails, and other personal information you disclose on online forms. Imagine what they can do with all that data.

A keylogger spotted on hundreds of HP laptops

In early December, a security researcher discovered a keylogger pre-installed on an HP laptop. This led to the revelation that more than 460 HP laptop models, including ProBook, Pavilion, EliteBook, and the Envy line include the Synaptics touchpad driver — which can be used as a keylogger.

Even though the keylogger on those HP laptops isn’t activated by default, an attacker who gains access to your laptop can enable it without much difficulty. HP themselves said the keylogger code had been added to the software by mistake and they’ve since released patches to fix the issue.

What should HP laptop users do?

If you own an HP laptop, check whether you’re affected by referring to this full list of affected models. If your laptop model is on the list, click on the link provided on the right side of the model name and download the security patch immediately to remove the keylogger from your computer.

How to protect yourself from keyloggers

The standard security measures — which you should be taking to heart and keeping up to date — can help protect you from keyloggers. You should avoid suspicious websites and never download files from them, and take extra care when opening attachments, text messages, or social media links from unknown senders since they can be embedded with a keylogger.

You should also have antivirus software installed and keep it up to date. Most antivirus software nowadays has already added keyloggers to their databases. It’s also good to be aware of the latest security patches from your hardware manufacturers and software developers since they’re made to fix current vulnerabilities.

And to make things even more secure, consider using one-time passwords and two-step verifications when you need to log in to important online services, such as those related to personal finance or services that require sensitive personal data.

Equifax sheds light on incident response

October 3, 2017 admin Security 2017october3security_c, cybersecurity, data breach, equifax, incident response, security

What would you do right now if you discover that your business’s database is hacked and a huge number of your customers’ data gets leaked? Speechless, with dismay, but you need to act, decently. In this case, it helps to have a good incident response plan in place, so your business won’t suffer the same fate as Equifax, which is an interesting story we’re about to tell.

What happened to Equifax?

Equifax, the huge American credit agency announced in September 2017 that its database was hacked, resulting in a leak of tons of consumers’ private data, including personally identifiable information of around 143 million US citizens. It included names, social security numbers, addresses, birthdates, and credit card and driver’s license numbers.

Equifax responded by setting up a new site, www.equifaxsecurity2017.com, to help its customers determine whether they had been affected and to provide more information about the incident.

Soon after, Equifax’s official Twitter account tweeted a link that directed customers to www.securityequifax2017.com, which is actually a fake site.

Fortunately for Equifax’s customers, the fake phishing site was set up by a software engineer who wanted to use it for educational purposes and to expose flaws in Equifax’s incident response practice. So, no further harm was done to the already-damaged customers, and Equifax is left with even more embarrassment.

So what did Equifax do wrong?

One of the huge mistakes Equifax made in responding to its data breach was setting up a new website to give updated information to its consumers outside of its main domain, equifax.com.

Why? You first need to know that since the invention of phishing scams, phishers have been creating fake versions of big companies’ websites. That’s why so many major corporations buy domains that are the common misspellings of their real domains.

You should also know that phishers can’t create a web page on the company’s main domain, so if Equifax’s new site was hosted there, it’d be easy for customers to tell whether the new page was legitimate and not be fooled by a fake domain name.

What’s obvious from this embarrassing misstep is that Equifax had never planned for a data leak. And this is an unforgivable oversight by a company that handles the information of over 800 million consumers and more than 88 million businesses worldwide.

Don’t repeat Equifax’s mistake

Whether your business is a small startup or as big as Equifax, it needs to prepare for a data breach. Besides having a comprehensive network defense plan, you also need to have the right incident response plan in place.

So what you should do after you’ve discovered the leak is, first of all, be upfront with your customers and notify them as soon as possible.

You also need to establish a message that includes the following information:

How the leak occurred
How the leak could affect your customers
How you will prevent future attacks
What your company will do to support affected customers

You should also create a web page to keep your customers up to date. But remember, the new web page should be under your company’s primary domain name.

As we’ve seen from Equifax, an incident response plan that’s robust is a must. Feel free to talk to our experts about how you can come up with an acute one — so you won’t have to repeat Equifax’s apologetic statement, since it doesn’t help the company redeemged reputation at all.

Locky-type ransomware is attacking systems

August 30, 2017 admin Security 2017august30security_c, locky, malware, ransomware, security, trojan

A new, Locky-type ransomware is currently infecting tens of thousands of computers worldwide. It uses the same code from the 2016 version to encrypt users’ files and it looks poised to cause another massive cyber emergency. Here’s everything we know so far.

Quick facts

According to a threat intelligence report, the email-based ransomware attacks started on August 9 and were detected through 62,000 phishing emails in 133 countries in just three days. It also revealed that 11,625 IP addresses were used to carry out the attacks, with the IP range owners consisting mostly of internet service providers and telecom companies.

How it works

The malicious email contains an attachment named “E 2017-08-09 (580).vbs” and just one line of text. Like the original Locky authors, attackers responsible for the new variant deploy social engineering tactics to scam recipients into opening the attached .doc, zip, pdf, .jpg or tiff file, which installs the ransomware into their systems.

When an unsuspecting user downloads the file, the macros run a file that provides the encryption Trojan with an entry point into the system. The Trojan then encrypts the infected computer’s files.

Once encryption is completed, the user receives instructions to download the Tor browser so they can access the “dark web” for details on how to pay the ransom. To retrieve their encrypted files, users will be asked to pay from 0.5-1 Bitcoin.

What you need to do

This ransomware variant builds on the strengths of previous Trojans. In fact, the original Locky strain made it easy for cyber criminals to develop a formidable ransomware that could evade existing cyber security solutions. This is why adopting a “deny all” security stance, whereby all files are considered unsafe until proven otherwise, is the best way to avoid infection.

Here are other tips to avoid infection:

Don’t open unsolicited attachments in suspicious emails. Alert your IT staff, and most importantly disallow macros in Microsoft Office unless they’ve been verified by your IT team.
Performing regular backups guarantees you never have to pay cyber criminals a ransom. If all other security measures fail, you can always rely on your backups, which protect your business not just from cyber crime-related disasters, but also from natural and other unforeseen system failures.
Train your staff to identify online scams like phishing. This and other similar ransomware strains take advantage of users’ lack of cyber security training.
Update your operating systems as soon as updates become available to reduce, or eliminate, the chances of your system’s vulnerabilities being exploited.

Even with a trained staff and the latest protections installed, your IT infrastructure may still have unidentified security holes. Cyber security experts can better evaluate your entire infrastructure and recommend the necessary patches for your business’s specific threats. To secure your systems, get in touch with our experts now.

5 ways to protect your IoT devices

July 24, 2017 admin Hardware 2017july24hardware_c, firmware, hardware, internet of things, iot, network, password, security, UPnP

Just a few years ago, smart appliances seemed like novelty products for rich business owners. Now, the Internet of Things (IoT) has become a viable solution for putting your business ahead of the curve. But whether it’s a smart fridge or a surveillance camera that connects to your phone, IoT devices should be treated and secured just like any computer in a network.

Set passwords
Many often forget they can set passwords for IoT devices. When this happens, they tend to leave their gadgets with default passwords, essentially leaving the door open for hackers. Make sure to set new and strong passwords — preferably with a combination of upper and lower case letters, numbers, and symbols — for each device connected to your network. Then, use a password manager to securely keep track of all your passwords.

Disable Universal Plug and Play (UPnP)
UPnP is designed to help IoT gadgets discover other network devices. However, hackers can also exploit this feature to find and connect to your IoT devices. To prevent them from getting to your network, it’s best to disable this feature completely.

Create a separate network
When you’re dealing with IoT devices, it’s wise to quarantine them in a separate network unconnected to your main office network. By doing this, user gadgets will still have access to the internet but won’t be able to access mission-critical files.

You should also consider investing in device access management tools. These allow you to control which devices can access what data, and prevent unauthorized access.

Update your firmware
If you want to keep your devices secure against the latest attacks, then you need to keep your IoT software up to date. Security researchers are always releasing security patches for the most recent vulnerabilities, so make it a habit to regularly check for and install IoT firmware updates. If you have several gadgets to secure, use patch management software to automate patch distribution and set a schedule to check for updates monthly.

Unplug it
Disconnecting your IoT devices from the internet (or turning them off completely) whenever you don’t need them significantly reduces how vulnerable you are to an attack. Think about it, if there’s nothing to target, hackers won’t be able to make their move. Turning your IoT devices on and off again may not seem like the most convenient strategy, but it does deny unauthorized access to your router.

Unfortunately, as IoT devices become more commonplace in homes and offices, more hackers will develop more cunning ways to exploit them. Getting into the above mentioned security habits can protect you from a wide variety of IoT attacks, but if you really need to beef up your security, then contact us today. We have robust security solutions that keep your hardware safe.

Worrying evidence of poor router security

June 27, 2017 admin Security 2017june27security_c, cia, firmware, routers, security, wannacry, wikileaks, wireless networks

Adding to the list of reasons to outsource your network security to a certified IT provider, a recent CIA leak shows just how vulnerable most network routers really are. Read on to learn why this is such a big vulnerability and what you can do to fix it.

The Wikileaks CIA documents

For several months, the notorious website famous for leaking government data has been rolling out information it obtained from the Central Intelligence Agency. The documents detail top-secret surveillance projects from 2013 to 2016 and mainly cover cyber espionage.

In the most recent release, documents describe government-sponsored methods and programs used to exploit home, office, and public wireless routers for both tracking internet browsing habits and remotely accessing files stored on devices that connect to compromised networks.

Is my router one of them?

According to the documents, 25 models of wireless routers from 10 different manufacturers were being exploited by the CIA. They weren’t off-brand budget devices either; the list includes devices from some of the biggest names in wireless networking:

Netgear
Linksys
Belkin
D-Link
Asus

Those brands account for over a third of wireless routers on the market, which means there’s a good chance you’re at risk.

After WannaCry used a previous CIA leak to fuel its global spread, you need to worry about more than just being a target of government espionage too. Over the past few years, almost all of these leaks have quickly made their way into criminal hands.

Patching vulnerabilities

Fixing security gaps in hardware is tricky business, especially when they’re mainly used to monitor rather than corrupt. In most cases, there will be no visual cues or performance problems to indicate your hardware has been infected. As such, you should plan on regularly updating the software on your hardware devices whenever possible.

Accessing your router’s software interface isn’t a user-friendly experience for non-IT folks. Usually, to access it, you need to visit the manufacturer’s website and log in with the administrator username and password. If these are still set to the default “admin” and “password” make sure to change them.

Once logged in, navigate through the settings menus until you find the Firmware Update page. Follow the instructions and confirm that the firmware has been properly installed.

The CIA’s router leaks were vague, so we’re not even sure how recent they are. We are fairly certain, however, that all of the manufacturers have since patched the vulnerabilities. Regardless, updating your router’s firmware will protect from a number of cyber security risks. If you’re unable to finish the task on your own, one of our technicians can fix it, as well as any other firmware vulnerabilities, in a matter hours. All you need to do is call!

PC fixes are a drain on your company’s budget

June 9, 2017 admin Security 2017june9security_c, it budget, personal computers, security, wannacry

Security professionals should be beefing up your network security, implementing advanced firewall software, and identifying risks for possible breaches. In reality, they spend a huge chunk of their time troubleshooting issues on individual personal computers (PCs). That workflow is not ideal, but that’s what normally happens in many organizations. At what cost? Read on to find out.

Cost of fixes

According to a survey of technology professionals, companies waste as much as $88,660 of their yearly IT budget as a result of having security staff spend an hour or more per work week fixing colleagues’ personal computers. The ‘wasted amount’ was based on an average hourly salary of IT staff multiplied by 52 weeks a year. Other than knowing how much time is wasted, what makes things worse is that IT security staff are among the highest paid employees in most companies.

The fixes have mostly to do with individual rather than department- or company-wide computer problems that don’t necessarily benefit the entire company. The resulting amount is especially staggering for small- and medium-sized businesses (SMBs) whose limited resources are better off spent on business intelligence tools and other network security upgrades.

Other costs

All those hours spent on fixing personal computers often means neglecting security improvements. The recent WannaCry ransomware attacks, which successfully infected 300,000 computers in 150 countries, demonstrate the dangers of failing to update operating system security patches on time. It should be a routine network security task that, if ignored, can leave your business helpless in the face of a cyber attack as formidable as WannaCry. It didn’t make much money, but had it been executed better, its effects would have been more devastating to businesses, regardless of size.

Profitable projects could also be set aside because of employees’ PC issues. For SMBs with one or two IT staff, this is especially detrimental to productivity and growth. They can easily increase their IT budgets, but if employees’ negligible computer issues keep occurring and systems keep crashing, hiring extra IT personnel won’t do much good.

What businesses should do

The key takeaway in all this is: Proactive IT management eliminates the expenditure required to fix problematic computers. Bolstering your entire IT infrastructure against disruptive crashes is the first step in avoiding the wasteful use of your staff’s time and your company’s money.

Even if your small business has the resources to hire extra staff, the general shortage of cyber security skills also poses a problem. Ultimately, the solution shouldn’t always have to be increasing manpower, but rather maximizing existing resources.

Having experts proactively maintain your IT eliminates the need to solve recurring small issues and lets your staff find a better use for technology resources. If you need non-disruptive technology, call us today for advice.

Precautions against WannaCry ransomware

May 23, 2017 admin Business 2017may23business_c, antivirus, business continuity, cloud backup, external hard drive, security, software update, wannacry, windows

The WannaCry ransomware, a type of malware that encrypts a victim’s files and extorts them for money, has already affected thousands of machines worldwide. Unfortunately, the success of this attack is just the beginning. According to security researchers, other hackers will probably develop stronger WannaCry variants in the coming months. And if you don’t want your business to become a victim of these attacks, you must take the following precautions.

Update your software
The first (and probably best) defense against WannaCry ransomware is to update your operating system. New research from Kaspersky shows that machines running Windows XP, 7 and outdated Windows 10 versions were affected by the ransomware. To check whether your systems are up to date, open your Windows search bar, look for Windows Update, click Check for Updates, and install any major updates.

Also, don’t forget to download the latest security patches for your business applications and security software.

Run security programs
Many antivirus programs now have mechanisms for detecting and blocking WannaCry malware; so when you’ve fully updated your security software, run a full system scan.

Keep in mind that antivirus isn’t a foolproof security solution. Instead, run it alongside other security applications like intrusion prevention systems and firewalls.

Use data backup and recovery tools
If WannaCry does infect your computers, only a solid data backup and recovery solution can save your business. Before ransomware strikes, periodically back up your files in both an external hard drive and a cloud-based backup service.

External hard drives will serve as your local backup solution for quick recovery times. However, we recommend keeping the external drive disconnected when it’s not being used and plugging it in only when you need to back up files at the end of the day. This is because when ransomware infects a computer, it will usually look to encrypt local backup drives as well.

Cloud-based backups, on the other hand, allow you to store files in remote data centers and access them from any internet-enabled device. When selecting a cloud services provider, make sure they provide the appropriate cloud protections to your files. For example, your backup vendor should provide reporting tools to keep track of any anomalies in your files. Document versioning features are also important. This allows you to recover older versions of a document in case the current version is encrypted.

After your local and cloud backups are set up, perform regular tests to ensure your disaster recovery plan works.

Stay informed
Finally, it’s important to stay on guard at all times. WannaCry is just one of many ransomware strains affecting businesses today, and in order to stay safe you need to be constantly up to date on the latest cybersecurity- and business continuity-related news.

Fileless malware: who are the targets?

March 3, 2017 admin Security 2017march3security_c, cybersecurity, fileless, malware, security, stuxnet

Business owners have spent the last couple months fearful of cyber attacks from the “fileless malware” plastered across headlines. The reality of this new threat doesn’t actually call for panic…yet. Getting acquainted with this new malware today could save you from a headache in the future.

What is this new threat?

To oversimplify the matter, fileless malware is stored somewhere other than a hard drive. For example, with some incredibly talented programming, a piece of malware could be stored in your Random Access Memory (RAM).

RAM is a type of temporary memory used only by applications that are running, which means antivirus software never scans it on account of its temporary nature. This makes fileless malware incredibly hard to detect.

This isn’t the first time it’s been detected

Industry-leading cyber security firm Kaspersky Lab first discovered a type of fileless malware on its very own network almost two years ago. The final verdict was that it originated from the Stuxnet strain of state-sponsored cyber warfare. The high level of sophistication and government funding meant fileless malware was virtually nonexistent until the beginning of 2017.

Where is it now?

Apparently being infected by this strain of malware makes you an expert because Kaspersky Lab was the group that uncovered over 140 infections across 40 different countries. Almost every instance of the fileless malware was found in financial institutions and worked towards obtaining login credentials. In the worst cases, infections had already gleaned enough information to allow cyber attackers to withdraw undisclosed sums of cash from ATMs.

Am I at risk?

It is extremely unlikely your business would have been targeted in the earliest stages of this particular strain of malware. Whoever created this program is after cold hard cash. Not ransoms, not valuable data, and not destruction. Unless your network directly handles the transfer of cash assets, you’re fine.

If you want to be extra careful, employ solutions that analyze trends in behavior. When hackers acquire login information, they usually test it out at odd hours and any intrusion prevention system should be able to recognize the attempt as dubious.

Should I worry about the future?

The answer is a bit of a mixed bag. Cybersecurity requires constant attention and education, but it’s not something you can just jump into. What you should do is hire a managed services provider that promises 24/7 network monitoring and up-to-the-minute patches and software updates — like us. Call today to get started.

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.

New year, new cyber-threats

December 13, 2016 admin Security 2016december13_security_c, cyber threats, cyber-attacks 2017, cybercrime, Network Security, protection, security

Have you had to deal with security issues in the past year? Brace yourself, as there are more to come. For this reason, security experts have become indispensable members of society, who guard tech-dependent individuals and businesses against malicious attacks that pose threats to their privacy and livelihood. As you ring in the new year, make sure you’re well armed against the following predicted cyber-crimes.

Increased threats on cloud technology

Cloud service has numerous benefits to businesses. They make data storage, collaboration, and processing more efficient; they enable employees to work faster; and they help operations flow smoother. Cloud technology’s popularity is expected to rise well into the next few years, but as demand increases, so does the dangers presented by cyber attackers.

Ransomware will be more complex

Ransomware incapacitates computer systems by locking down files and preventing access for ransom. In its 2016 Threat Predictions report, security software company McAfee predicts a peak in ransomware attacks next year. Although they also predict it to recede by mid-year, damages to vulnerable cloud-dependent infrastructures can be great and costly. Most alarming in the prediction, however, is that in the coming year ransomware attacks will be more complex due to new elements.

Ransomworms, which use advanced victimization techniques to mine further data within an already compromised network, are expected to put an even crueler spin to an already formidable malware. Doxing, on the other hand, affects avenues such as social media and any place where sensitive, easily identifiable information can be extracted to serve the ultimate purpose of extorting money. Yet another wicked ransomware to watch out for is Backup Deletion, which destroys the very mechanism that can otherwise help you recover from a compromised system or files: your backup data.

More threats to IoT (Internet of Things)-enabled devices

It is also predicted that 2017 will see attacks made on IoT-powered devices, which will make life harder for those who depend on technology that makes life easier. It targets medical devices and Electronic Medical Records, “connected cars”, basic domestic tools, and tech-driven wearables, such as smartwatches and fitness trackers. The danger posed by this intrusion is fully capable of corrupting information stored in your devices.

Advanced cyber espionage

Cyber espionage is by no means a novelty. In 2017, it’s expected to hold sway in cyber-threat prevention measures as it becomes even more complex. It encompasses all sectors of society, including individuals, private organizations, government institutions, and entire countries. Perpetrators will have the means to bypass networks by attacking firewalls and wreak havoc in their victims’ network. Fret not, for there will be measures in place to detect this threat also in the coming year.

Hackers are one of the most cunning criminals to have ever existed. While the cyber-police and the defenses they put up are no slouches, threats to security systems can still make technology-dependent individuals and businesses quiver. Although damaged networks can be repaired, compromised privacy restored, and stolen data returned, the amount of damage that hackers can cause might be irreparable and/or result in a significant dent in your IT infrastructure and budget. The value of a network security system makes itself known when you least expect it, which is why security should be a top priority.

Are your systems protected from these predicted remarkable feats of hacking? Call us if you want to discuss security services that are best for you.
