IT professionals know the damage that malware can cause, but everyday users are often unaware of the security threats lurking on the web, in their email and on their smartphones. Even the best malware defense can be rendered useless due to careless user behavior. To defend against data breaches, it’s critical to educate your users about the security threats and cybercrime tactics they face.
User training is a best practice used by organizations of all sizes to bolster their cyber defense. Take a page from their playbook. Educate your users and help them understand the critical role they play in preventing data breaches. When developing your user security education, lay a strong foundation by covering the basics first. Keep it simple; give users the information they need to understand the increasingly sophisticated nature of the threats they face.
We have compiled these 10 tips to help your users avoid common online threats. The following information is available to IT admins to share with users so they are more aware of the security traps they face every day.
Malware is malicious software code developed by cybercriminals to infect PCs, networks and mobile devices for the purpose of gaining access to and extracting sensitive data, typically for financial gain. There are more than 200,000 new malware threats created every day, and nearly 70% of data breaches involve malware.
The days of malware being created and released by hackers for fun and gaining notoriety are long gone. Today, malware fuels a global multi-billion dollar cybercrime economy.
You are their #1 target. Whether you’re using a PC at home or at work, you are just a tool for cybercriminals to gain access to the data they want to steal or the systems they want to hijack. To defend yourself and your organization’s data, it is important to understand that malware writers are becoming very adept at creating threats that evade detection by traditional security solutions. Don’t assume you can let your guard down or behave in a riskier manner because your PC at home or work is defended by antivirus, email security, firewall or other cyber defenses. One wrong click and your PC is infected, and data is at risk.
Some malware types – like viruses and Trojans – are tools for breaking into your PC, while others – like worms, spyware and key loggers – are all about snooping through a PC or network looking for particular systems to compromise and data to steal. Many data breaches involve multiple kinds of malware in a staged attack that progresses over time. It’s critical to understand that one infected PC may seem like a small problem, but it can lead to big trouble for the organization.
Still other malware – like bots or bot nets – are all about hijacking PCs to steal computing resources to launch other cyber-attacks. Instead of paying for legitimate IT infrastructure and equipment to start a spam campaign, scammers often secretly use a network of infected PCs around the world to distribute malicious email without users ever knowing.
Tip: Don’t underestimate how clever cybercriminals have become. Their tricks are extremely effective at luring users to open infected files, click on malicious links, unwillingly share malware with colleagues, and to freely divulge sensitive data. They understand how we behave online, and they know exactly what to do to infect us. Knowing the types of tricks and traps they use is the first step to defending yourself and the organization from malware.
Believe it or not, one of the most common ways that cybercriminals gain access to sensitive data is by tricking users into divulging information we ordinarily wouldn’t share with anyone. It’s called phishing, and it often involves using social engineering tactics to trick users into thinking they have been contacted by a service they know and trust – like Social engineering refers to the practice of creating deceptive attacks based on what is known about the targeted user. For example, cybercriminals scour users’ social media accounts like Facebook and LinkedIn to create phishing emails that look and read real enough to trick users into responding to fraudulent requests to change passwords, confirm payment options or divulge other personal information.
Phishing emails and the websites they link to look like the real thing and can be difficult to identify as malicious right away. URLs or web addresses also look legitimate. And since many people re-use the same password, a user’s login credentials for a bank account is often the same one they use to log on to the network at work every day. This enables cybercriminals to access the work network as if they were you.
Tip: Always keep in the mind that most of the services you use will never request that you share personal information directly via email. Moreover, the majority of time you are contacted to reset a password or confirm any changes to your account will be initiated by an action you take. In the event you receive an unsolicited email (even if it’s an alarming warning to reset a password), it is best to assume it is malicious. Do not click any links. Contact the service provider or check their website by entering the URL you always use.
Malicious spam remains a major threat to many organizations. These aren’t those annoying marketing emails we’re tired of deleting from our inboxes all day long. Think of malicious spam as a precursor to phishing, employing similar tricks of deception – stealing logos and designs from well-respected brands – to trick users into clicking malicious links or downloading infected files. Malicious spam could even come from an email address spoofed (manipulated) to appear as if it is from someone within your organization.
But one click of the mouse to open an infected Word document or PDF, and your PC may be infected. Just about any type of malware can be delivered via malicious spam. Cybercriminals use spam as a “shotgun” tactic to spread their malware as wide as possible. Often these emails are disguised as shipping confirmation notices, alarming notices from banks, tantalizing photos, mortgage scams, fake news alerts and more – anything to raise our curiosity and get us to open an email and click an attachment or link that only leads to trouble.
Tip: Always be wary of any email you receive that is out of the ordinary or you did not request. Spam can look very real, but avoid the temptation to click without thinking. Also, be aware that just because you’re at work and protected by security solutions, malicious spam can still slip through. Best course of action, if you think it’s spam, delete it.
Cybercriminals know what people are searching for online and talking about via social media, and they use that against us. While search engines like Google are very good at protecting us from these threats, cybercriminals are quick to stand up entire websites within hours of sensational news breaking, claiming video and pics, but only delivering malware to visitors. It may take Google a few hours to identify and remove these sites from its search results, but in that time plenty of users can be infected.
Tip: Get your celebrity gossip and news from trusted sites only. Always be careful what you’re searching for and what sites you visit on your lunch hour. Again, don’t assume you’re protected because work has better security than your home PC. Threats – especially newly created threats – can still slip through.
Two types of malware known as exploits and Zeroday attacks refer to cybercriminals taking advantage of vulnerabilities in the software products we use every day. These include operating systems like Windows, web browsers like Chrome, Internet Explorer and Firefox, and a wide range of popular applications like Adobe Flash and Reader, Java and Skype.
Malware writers invest a lot of time and energy searching for faulty software code they can exploit and use as a backdoor into your PC to deliver malware for any number of malicious purposes. Zero-day attacks are named as they are because at the time of their discovery there is no fix for the vulnerability they are exploiting, leaving software companies scrambling to release updates within a few days, which is plenty of time for cybercriminals to spread malware.
Tip: The best defense against malware exploits is to always update software programs to the latest available versions. When a message appears on your screen to update a trusted software application, do it. Chances are good the software developer is correcting an issue that may have serious security implications. If your organization uses an automated patching solution, these updates should be deployed automatically. However, be mindful of Zero-day alerts from IT, which may instruct you to avoid using certain programs when a threat is identified.
Cybercriminals know that users are concerned about security and often employ messages and pop-up screens that appear to be legit programs on your PC requesting updates. Clicking on these links can lead to downloading malware and installing rogue applications.
These rogues may claim to be antivirus products or system cleaning programs. Some even claim to be from the FBI. They look authentic, but they are designed to infect your PC to extort money from you, or to install additional malware on your computer.
Tip: If you see a warning claiming your PC is infected, don’t click anything. Contact IT. Don’t take the chance
There is a family of malware known as ransomware, and just like the name implies, these malicious programs take your PC hostage. By clicking on the wrong link in an email or by visiting an infected website, your PC can fall victim to malware that demands payment to be removed, or even worse large sums of money to regain access to your files. Hijacking users’ PCs and encrypting files so they are no longer accessible is an increasingly popular tool in the bad guys’ arsenal.
Tip: Avoid ransomware by being safe online, but be prepared for the worst and back up all critical files your business or operation can’t do without. And since ransomware is often delivered via malware exploits, keep your system patched and software up to date.
Malware is no longer limited to just PCs. With the rise of mobile devices and their proliferation in the workplace, malware writers have switched tactics to take advantage of these inviting targets. Malicious Android and iOS apps can cause all sorts of headaches – from running up international text charges to stealing personal data and passwords to transmitting infections to other devices, like your PC.
Tip: Don’t think that your Android or iOS device is safe from threats. Mobile malware is the fastest growing segment of malware. When downloading apps, only download from trusted sources (Google Play and Apple’s App Store) and only choose apps from trusted developers. Moreover, install a trusted security app onto your mobile device.
Just like people can spread the flu or a cold to colleagues, users can spread malware infections to their work PC and network. Two common ways this happens is by sharing files between a work and home PC that may not be as secure or is used by other family members who do not practice safe online habits.
Users may work on an infected document on their home PC and email it to their work computer or upload to the cloud where other users may access it, getting infected themselves. Moreover, removable storage devices, like USB sticks and external hard drives are often shared among users. Malware writers know this and create threats that are designed to stealthily move from these devices to PCs.
Tip: Only connect your PC to trusted devices and scan all USB drives with your antivirus software before opening any files. Be mindful of who is using a home PC if you are opening work documents on it. lways ask if you completely trust the surfing habits of your 13-yearold son or daughter.
Security threats on social media continue to grow exponentially. Shortened links are effective tools to hide malicious URLs, and threats tied to compelling images and videos shared on Facebook can spread quickly among friends. Cyber criminals can quickly set up fake accounts and profiles to spread malware, typically employing the same social engineering tactics they’ve perfected. Moreover, cyber criminals can hijack your profiles and accounts to spread malware under your name to people you’re connected to.
Tip: Be careful what you click on Facebook, Twitter, LinkedIn and other popular social channels. Only share and click on posts from trusted sources, and be mindful that it’s possible your friends are sharing malware. Also, use different passwords for all your accounts, so if one is compromised the others are still secure.
By adopting these 10 tips, users can do their part to protect their network from data breaches, protecting critical data, safeguarding customer privacy and defending your organization’s reputation.
