How Much Could A Ransomware Attack Cost Your Business?

Posted on 23/05/2017 by David Perkovic

How much is your data is worth? Information is probably the most valuable part of your business. Imagine if you lost your client database, accounting software, inventory management and any intellectual property you may own. How long will it take to recreate this data and how much money would you lose in lost productivity, staff wages and the time it takes to either recover or recreate the lost information?

Recently when the WannaCry ransomware spread through out the world, many businesses were suddenly forced to re-assess the value of their data: was it worth saving and what would be the ongoing costs of the attack?

If you don’t have a recent backup most ransomware attacks cost at least $US200 (if not a lot more) to get your files released and that is only IF the cyber criminals honor the payment and actually give you the decryption key (some even demand further payments). Meanwhile your business is still running and new client calls are still coming in and you may find yourself unable to operate with your systems down.

Paying the ransom may seem like a quick fix but:

There is still the downtime involved to restore your data resulting in lost productivity.
If word gets out that your data has been compromised you may find confidence in your business plummets and your existing clients head elsewhere.
The cyber criminals you pay, may now see you as an easy target and demand more money or target you for other scams and malware activity.
You may recover the data but is it compromised with other malware?
You may not get back all the data that has been lost.

So that $US200 ransom may end up costing many, many thousands of dollars!

How To Prevent Ransomware Attacks on your Business

Keep your systems up to date: Malware can take advantage of flaws in older versions of Windows and software – sometimes ones that have already been patched by Microsoft and third party vendors. To be protected businesses have to stay up to date with their patches & versions. To be up to date with Windows patches you need to be running a supported version of Windows. Delaying patches and updates puts your business at risk – we can help you keep you systems up to date.

Use corporate grade security software and firewall: Free software may be fine for low end home computers but if the worst happens you will get no support or help from a company providing free software. A firewall or UTM (unified threat management) device can also help block malware and ransomware infections. But whether it is a free or paid for solution the software (and any hardware devices) must be kept up to date.

Lock down employee computers: Very few staff will require full administrator access to your business network. With a higher level of permissions the more damage a person can do – either accidentally or by inadvertently installing malware. By locking down your computers you have a better chance of containing a malware attack to non-vital systems. Our expert computer technicians can design an access management plan that gives you best of both worlds – flexibility and security.

Educate your workplace: Most employees believe they are being cyber-safe but in reality it is quite different. Many malicious links and embedded malware have become harder to spot – and all it takes is a microsecond to click (and later regret it). We can work with your staff to establish procedures around checking links for authenticity before clicking, awareness around verifying the source of attachments and the importance of malware scanning and keeping systems up to date. We can help get the message through!

Have a solid backup plan: When ransomware hits, a connected backup = infected backup. Also a lot of cloud backup systems, such as Dropbox, immediately clone the infected files which also renders the cloud copy useless. The only safe backups will be the ones both physically and electronically disconnected. Our experts can set you up with a backup system that makes recovery simple.

Be proactive: The best way to avoid the costs of a ransomware attack is to prevent it from happening in the first place is with up to date antivirus software, regular systems updates and security audits. Remember, many businesses were able to watch WannaCry from the sidelines, completely unaffected and seized opportunities while their competitors were down.

WannaCry Ransomware Explained: Is Your Business At Risk?

Posted on 22/05/2017 by David Perkovic

With all the media attention last week you would be hard-pressed to not of heard about the WannaCry cyber-attack. Businesses of all sizes and even hospitals and police departments found themselves crippled with out warning.

Here in Australia we looked to have missed a large part of the attack due to the time zone differences and the fact that a kill switch was found for the malware. We shouldn’t rely on these factors going forward though. This articles details what the malware is, why it caused so much damage and how to protect ourselves moving forward.

What is WannaCry?

The WannaCry cyber-attack was a type of malware (the collective name for malicious software which includes viruses, worms and spyware) called ‘ransomware’. Just like the name suggests, it actually demands money from the owners of the computers infected. Like all ransomware attacks, WannaCry encrypts your files and holds them hostage until payment is made – in this case, the price was set at $300 payable with the internet currency Bitcoin (and you had 3 days to pay before it doubled). If you don’t pay the ransomware threatens to permanently delete all your files. It is not yet known how much money the WannaCry hackers have earned with their latest attack – but you can be sure that plenty of people have paid the ransom. Even the FBI recommends paying the ransom – especially if the ransomed files are of a sensitive nature or weren’t backed up.

How It Spread So Fast

WannaCry self-replicates and spreads. So far, no common trigger has been identified, as is normally the case with phishing links (a phishing attack needs to be activated – usually with a click). WannaCry moved rapidly from system to system, spreading out through the entire network, including all connected backups and storage devices. At the same time it infected other networks, who then spread it further and further. Given the nature of the internet it had spread widely within hours.

Why Some Businesses Were Safe

WannaCry took advantage of a specific vulnerability in Windows of which Microsoft patched months ago. Thus only systems that have fallen 2 months behind in their Windows updates were infected. Without that patch, the ransomware could waltz right past the firewall, past the anti-virus and directly into the system (the NHS were reportedly running Windows XP – which is no longer supported by Microsoft). Those running Windows 10 or a fully patched, recent version of Windows were completely unaffected as the virus literally had no way in

This outbreak shows the importance of staying up to date with security patches on your systems. We haven’t yet seen a second spike in WannaCry attacks yet, but that doesn’t mean there won’t be one. A quick Windows update could protect your business from weeks of downtime and lost revenue making attacks like this a non-issue.

With our regular maintenance plans we can make sure you stay up to date and protected. Give us a call today at 08 8326 4364 to discuss ways we can help your business stay safe.

How To Stay Cyber Safe When Travelling

Posted on 30/04/2017 by David Perkovic

With cloud computing people are embracing the flexibility of working away from the office (whether at home or travelling) and working by simply accessing the relevant data or applications via the internet..

When in the office, you are protected by professionally designed firewalls, security infrastructure, and robust software. As soon as you step away from that network those protections disappear and leave your device and the data inside at greater risk.

Cyber attackers love to collect any data they can obtain – business or personal doesn’t matter to them as it can all be sold. These days the information stored on your device can be worth much more than the actual device.

Here are 3 ways a hacker may attack:

Random Opportunity: If you have left your laptop at a café or a thief has stolen the phone from your pocket, the outcome is the same – that device is gone. Hackers take any opportunity they can to gain access to a device: including taking them from hotel rooms and even asking to ‘borrow’ them for a few minutes – if they don’t steal it the device is handed back laden with spyware.

Creating a fake Wi-Fi Hotspot: We’ve all come to expect free Wi-Fi networks wherever we go. Hackers though will take advantage of this to create their own free, unsecure network just waiting for someone to connect. Once a user is connected a hacker can grab any unsecured passwords sent across the network.

Intercepting an Unsecure Network: Hackers don’t even need to own the Wi-Fi network to steal content from it. Data traveling across an unsecure network is visible and available to anyone with the right software.

Don’t let these issues stop you using the Internet when out side the office. Just take the following precautions to increase your cyber safety and help protect your valuable data:

Regularly make backups: In the event your device is lost or damaged, you’ll be able to replace the device with a new one and quickly restore all the data from a backup, all with minimal downtime.
Be careful when using public Wi-Fi: Don’t use passwords or email when on a public network. Use a VPN or a 4G connection (ie tether your computer to your phones data connection) when you are accessing sensitive data or logging in to secure sites.
Use passwords and encryption: At a minimum, make sure your device is password protected and has full drive encryption. With a password and drive encryption even if your storage drive is removed from the device the contents are inaccessible.
Act fast after loss: If your device is lost or stolen, immediately notify the appropriate companies and people. This might include your IT provider so they can change passwords, your bank and any other financial institutions so they can lock down accounts, and any staff who need to be aware of the breach so they aren’t tricked into allowing further breaches.

Should I Pay For Antivirus Software?

Posted on 20/02/2017 by David Perkovic

Its the age old question that I regularly hear – is free antivirus software as good as a paid for solution?

In a perfect world the best way to avoid a computer virus is by using common sense – but that doesn’t always work with even the most careful users finding themselves infected in an instant. This is why antivirus software exists to help us not get infected – but should you choose free or paid antivirus? Here we list some of the differences between the two:

Advertising: Much like a free game making its fortune with advertising and in-app purchases, free antivirus software will push you for payment. Expect popup boxes pestering you to sign up to the paid version. Some free options will also try to change your browser home page and default search engine, an inconvenience you may be stuck with. Paid options are more respectful and largely invisible unless they have detected a problem.

Effectiveness: It is fair to expect your antivirus to detect malware, and testing shows that in a head-to-head battle free and paid are roughly equal at catching known infections. Generally free antivirus needs to have recorded a virus to its library before it can detect it. Paid antivirus is more likely to identify and stop new viruses – they can detect suspicious behavior, source and attributes and are a far more effective method of detection.

Features: Free antivirus is usually a cut down version of a paid version. In a paid version you can expect advanced features like spam filters, firewalls, parental controls and secure web browsing. Some paid antivirus packages also update your other software applications, forming a more secure protection against attack.

Support: Free antivirus options are very popular because they are free! This means there is generally no support available. If there’s a problem or conflict with another program, you may find yourself without protection until it can be resolved. Paid antivirus options usually include telephone suppor and other forms of support, ready to help with problems ranging from installation to system diagnostics.

Ease of use: Free antivirus packages are generally easy to install and use, but are limited in their flexibility. They come as-is, meaning you can’t pick and choose what it monitors or how it reacts. For example, users occasionally find it necessary to disable ALL protections in order to install a network game. Paid versions are more likely to allow you to adapt the way it runs, switching features on and off as required.

In summary free antivirus software is fine for very basic protection, those on a budget or with an older PC – in these cases, something is always better than nothing. But we generally recommend you go with a paid antivirus solution to defend you from the new attacks that are released daily and to ensure you have solid protection that will make a real difference to your digital safety.

Will Clicking That Link Cost You Thousands?

Posted on 06/01/2017 by David Perkovic

Ransomware has been a huge security threat in 2016. No-one was safe. Hackers targeted everyone and everything – including office networks and home PCs. In fact anything connected to the Internet (including smart TV’s and surveillance cameras) was fair game for them. They were very successful, with reports of upwards of $US846million reported just from incidents in the US. With this sort of monetary gain business is booming for hackers, with thousands of attacks each day bringing in an average of $US640 per target. Even more alarmingly is that the cost to the end user is on the rise with hackers demanding more and more money each time.

Some hackers even offer to help and rescue you from the issue that they caused – for a fee of course! One method is to trick you into thinking you have a virus or malware issue that will spread rapidly if you don’t pay them money to remove it. Another scarier method is that they pretend to be from a law enforcement agency (ie the Federal Police, FBI or a similar type of organisation) and say your computer was involved in a crime (anything from money laundering to child pornography). If you pay them a certain amount of money quickly you can avoid going to prison.

The real bad malware that is spreading rapidly at the moment are the crypto range of viruses. These viruses cause users to be locked out of their own data by encrypting files on users computers and servers. Folders of business documents, pictures, photos, music and even financial records are all held hostage until a ransom is paid. The encryption is such that it is unbreakable and unless you have a good backup paying the ransom is often seen to be the only solution.

The way these evil hackers get into your computer is deviously simple. They convince users to click on an email attachment/link or pop-up. For example you receive an email or pop up that:

supposedly tracks an undeliverable package.
is a bill or credit from a utility company.
alerts you to a virus that was found and needs to be removed.
an invoice from a company you have never heard of and / or for goods you never ordered.
advises you of a recent traffic or some other type of fine.

They make the message so tempting to click through for more details (this is what the hackers count on). Their messages and pop-ups aren’t obvious threats and so can easily slip under our radar and through various spam and virus filters.

Paying the hackers to solve or unencrypt your files is not recommended as they are not the most trustworthy bunch. That one payment may lead to demands of more and more money with no solution in sight.

To make things worse, the malware can encrypt your backups too. Having a backup is very important in any situation, but in cases like this, the right backup is needed – with several other backup copies not connected to your network and stored safely offsite. An online backup is also recommended. Before restoring your backup remember to check that the malware isn’t lurking in the background, ready to not just re-infect your restored files but also the backup drive itself.

To avoid finding yourself dealing with ransom demands we recommend being wary of all email attachments. Even if they are from business associates, friends and family – if you are not sure what the file is don’t click it. The sender may not have sent that email intentionally and their compromised system may be automatically emailing everyone in their address book.

You should also be wary with any popups that appear out of place, especially ones that try to make you panic or do something you are wary of doing. If the message doesn’t sound or look right then don’t click it. Ransomware is just too dangerous to risk.

Also make sure your backups are working correctly and regularly test your backups.

Six Quick Security Tips To Keep Your Business Safe

Posted on 08/11/2016 by David Perkovic

Every employee shares one inescapable flaw that is putting businesses at risk – they are human.

Up to 59% of data breaches can be traced back to something an employee did or didn’t do, which helped create a security incident or cyber-attack.

To help prevent security issues build security awareness and respect into your company culture, so that maintaining digital security becomes as simple as making a cup of coffee.

Use complex passwords: Every employee, including management and owners, need to use an alphanumeric password that they haven’t used before. Password managers can assist with making sure they’re never forgotten.

Verify unknown identities: Not familiar with ‘Jenny from Accounting’ who has called to ask for sensitive information? Double check the callers identity and access permissions before releasing any information. Hackers love to play on our desire to help other people.

Encrypt by default: People regularly transfer data to a laptop, USB drive or smartphone so they can work offsite. Unfortunately this equipment can be easily stolen or lost. Set operating systems to encrypt data by default, so that it becomes useless in the wrong hands.

Protect portable devices: Laptops, mobile phones and other portable devices should always require a password and be set to auto-lock after a short period of time. Never leave them unattended in cars, buses, restrooms etc, and if travelling by plane take them on-board as carry-on luggage.

Set personal usage rules: Many businesses block productivity-vacuums such as Facebook and other websites but what are the rules regarding games, video streaming or shopping? Can users install their own software? When business devices are used for personal usage, security tends to slide which results in unintentional malware installation. Also don’t let the employees spouse or children use any company device.

Educate often: People often fall into the “it won’t happen to me” mindset. As security threats change regularly have a quick five minute discussion once a month to remind staff that you always need to be vigilant.

Some things to discuss with staff are:

Links in emails – Hackers often send emails that look like they are from your bank, phone company or similar. Be sure to check the link by hovering over it with your mouse. This method of attack is known as ‘phishing’.
Tech scam popups – Be on the lookout for popups advising that your computer is infected and you need to call a phone number or download software.
Email attachments – Never open an unknown attachment and even from people you know and trust. If you are not expeciting an attachment from the sender always contact them to confirm and scan for malware before opening.

How To Spot A Tech Scam

Posted on 07/09/2016 by David Perkovic

Scammers swindle millions from people every day.

If your computer had a security problem, you’d want to know about it ASAP, right?

Before your important files are corrupted, your photos lost and your digital life destroyed. Even thinking about gives me the shivers.

Tech scammers know we’d be lost without our computers, and that we don’t always know what’s going on behind the screen – which is why they’ve been able to swindle millions from every day people across the world.

The scam goes like this:

Scams One day out of the blue you receive a phone call from someone with a heavy accent (usually Indian) saying they’re from Microsoft (or some other company) or worrying pop-up appears on your screen, saying your system has been infected with a virus.

To fix the problem, the caller or the pop up says you to download some support software, which they’ll give you a special link for.

A technician then uses that software to gain access to your system and make it appear your system is riddled with viruses. Flashing screens, mysterious diagnostics whizzing by, fabricated errors…they’ll do or say anything to make you panic. They’ll even go as far as claiming your system has been infected with illegal content and if not corrected you will face criminal charges.

Demands for credit card information follow soon after. Once the card details are provided, they simply stop fiddling with your system to make it seem the problem is fixed. To continue the scam, they’ll soon access your system to recreate the problem, this time offering a ongoing paid subscription for ongoing protection.

What To Do If You’re Targeted By A Tech Scam

1. Don’t taunt them. Just hang up. Right now you’re only a phone number in their system and they’ll move onto the next – if you give them cause to target you personally, you may find yourself in a dangerous situation.

The real Microsoft will never randomly call people like this. Ever.

2. If a pop-up appears, immediately run an anti-virus scan. Don’t click the pop-up or call the number.

What To Do If You’ve Already Been Scammed

It’s okay. It feels horrible, but you’re not alone and the situation can be corrected.

Call your financial institution and have the charges reversed and your card reissued. It’s easier than you might think and helps the authorities locate the scammers.

Then give us a call on 08 8326 4364 (or support@dpcomputing.com.au) and we’ll make sure they no longer have access to your computer.
