Farewell, summer. Hello, back-to-school season! While the chill may not be in the air yet, parents may be feeling the slight shiver of unease as their kids, tweens, teens, and young adults return to school and become re-entangled with the technology they use for their education and budding social lives. 

Before they hop on the bus or zoom off to college, alert your children to the following 10 online cybersecurity best practices to ensure a safe school year online. 

1. Keep Track of Mobile Devices

It sounds obvious but impart the importance to your kids of keeping their eyes on their devices at all times. Lost cellphones and laptops are not only expensive to replace but you lose control of the valuable personally identifiable information (PII) they contain. Protect all devices with unique, hard-to-guess passwords. Even better, enable biometric passwords, such as fingerprint or face ID. These are the hardest passwords to crack and can keep the information inside lost or stolen devices safe. 

2. Don’t Share Passwords

Streaming services host the most buzzworthy shows. All their friends may be raving about the latest episodes of a zombie thriller or sci-fi visual masterpiece, but alas: Your family doesn’t have a subscription to the streaming service. Cash-conscious college students especially may attempt to save money on streaming by sharing passwords to various platforms. Alert your children to the dangers of doing so. Sharing a password with a trusted best friend might not seem like a cyberthreat, but if they share it with a friend who then shares it with someone else who may not be so trustworthy, you just handed the keys to a criminal to walk right in and help themselves to your PII stored on the streaming service’s dashboard.     

Once the cybercriminal has your streaming service password, they may then attempt to use it to break into other sensitive online accounts. Criminals bank on people reusing the same passwords across various accounts. So, make sure that your children always keep their passwords to themselves and have unique passwords for every account. If they’re having a difficult time remembering dozens of passwords, sign them up for a password manager that can store passwords securely. 

3. Keep Some Details a Mystery on Social Media

Walk down any city or suburban street, and you’re likely to see at least one Gen Zer filming themselves doing the latest dance trend or taking carefully posed pictures with their friends to share on social media. According to one survey, 76% of Gen Zers use Instagram and 71% are on social media for three hours or more every day.1 And while they’re on social media, your children are likely posting details about their day. Some details – like what they ate for breakfast – are innocent. But when kids start posting pictures or details about where they go to school, where they practice sports, and geotagging their home addresses, this opens them up to identity fraud or stalking.  

Encourage your children to keep some personal details to themselves, especially their full names, full birthdates, address, and where they go to school. For their social media handles, suggest they go by a nickname and omit their birthyear. Also, it’s best practice to keep social media accounts set to private. If they have aspirations to become the internet’s next biggest influencer or video star, they can create a public account that’s sparse on the personal details. 

4. Say No to Cyberbullying

Cyberbullying is a major concern for school-age children and their parents. According to McAfee’s “Life Behind the Screens of Parents, Tweens, and Teens,” 57% of parents worry about cyberbullying and 47% of children are similarly uneasy about it. Globally, children as young as 10 years old have experienced cyberbullying.  

Remind your children that they should report any online interaction that makes them uncomfortable to an adult, whether that’s a teacher, a guidance counsellor, or a family member. Breaks from social media platforms are healthy, so consider having the whole family join in on a family-wide social media vacation. Instead of everyone scrolling on their phones on a weeknight, replace that time with a game night instead. 

5. Learning and Failing Is Always Better Than Cheating

ChatGPT is all the rage, and procrastinators are rejoicing. Now, instead of spending hours writing essays, students can ask artificial intelligence to compose it for them. ChatGPT is just the latest tool corner-cutters are adding to their toolbelt. Now that most kids, tweens, and teens have cellphones in their pockets, that means they also basically have cheating devices under their desks. 

To deter cheating, parents should consider lessening the pressure upon their kids to receive a good grade at any cost. School is all about learning, and the more a student cheats, the less they learn. Lessons often build off previous units, so if a student cheats on one test, future learning is built upon a shaky foundation of previous knowledge. Also, students should be careful about using AI as a background research tool, as it isn’t always accurate. 

6. Phishing

Phishing happens to just about everyone with an email address, social media account, or mobile phone. Cybercriminals impersonate businesses, authority figures, or people in dire straits to gain financially from unsuspecting targets. While an adult who carefully reads their online correspondences can often pick out a phisher from a legitimate sender, tweens and teens who rush through messages and don’t notice the tell-tale signs could fall for a phisher and give up their valuable PII.  

Pass these rules onto your students to help them avoid falling for phishing scams: 

• Never share your passwords with anyone. 
• Never write down your Social Security Number or routing number or share it via email. 
• Be careful of electronic correspondences that inspire strong feelings like excitement, anger, stress, or sadness and require “urgent” responses.  
• Beware of messages with typos, grammar mistakes, or choppy writing (which is characteristic of AI-written messages). 

7. Social Engineering

Social engineering is similar to phishing in that it is a scheme where a cybercriminal ekes valuable PII from people on social media and uses it to impersonate them elsewhere or gain financially. Social engineers peruse public profiles and create scams targeted specifically to their target’s interests and background. For instance, if they see a person loves their dog, the criminal may fabricate a dog rescue fundraiser to steal their credit card information. 

It’s important to alert your children (and remind your college-age young adults) to be on the lookout for people online who do not have pure intentions. It’s safest to deal with any stranger online with a hefty dose of skepticism. If their heartstrings are truly tugged by a story they see online, they should consider researching and donating their money or time to a well-known organization that does similar work. 

8. Fake News

With an election on the horizon, there will probably be an uptick in false new reports. Fake news spreaders are likely to employ AI art, deepfake, and ChatGPT-written “news” articles to support their sensationalist claims. Alert your students – especially teens and young adults who may be interested in politics – to be on the lookout for fake news. Impart the importance of not sharing fake news with their online followings, even if they’re poking fun at how ridiculous the report is. All it takes is for one person to believe it, spread it to their network, and the fake news proponents slowly gather their own following. Fake news turns dangerous when it incites a mob mentality. 

To identify fake news, first, read the report. Does it sound completely outlandish? Are the accompanying images hard to believe? Then, see if any other news outlet has reported a similar story. Genuine news is rarely isolated to one outlet.   

Parents with students who have a budding interest in current events should share a few vetted online news sources that are well-established and revered for their trustworthiness. 

9. Browse Safely

In a quest for free shows, movies, video games, and knockoff software, students are likely to land on at least one risky website. Downloading free media onto a device from a risky site can turn costly very quickly, as malware often lurks on files. Once the malware infects a device, it can hijack the device’s computing power for the cybercriminal’s other endeavors or the malware could log keystrokes and steal passwords and other sensitive information. 

With the threat of malware swirling, it’s key to share safe downloading best practices with your student. A safe browsing extension, like McAfee Web Advisor, alerts you when you’re entering a risky site where malware and other shifty online schemes may be hiding. 

10. Stay Secure on Unsecure Public Wi-Fi

Dorms, university libraries, campus cafes, and class buildings all likely have their own Wi-Fi networks. While school networks may include some protection from outside cybercriminals, networks that you share with hundreds or thousands of people are susceptible to digital eavesdropping.   

To protect connected devices and the important information they house, connect to a virtual private network (VPN) whenever you’re not 100% certain of a Wi-Fi’s safety. VPNs are quick and easy to connect to, and they don’t slow down your device.  

Gear Up for a Safe School Year 

While diligence and good cyber habits can lessen the impact of many of these 10 threats, a cybersecurity protection service gives parents and their students valuable peace of mind that their devices and online privacy are safe. McAfee+ Ultimate Family Plan is the all-in-one device, privacy, and identity protection service that allows the whole family to live confidently online.

One frustrating aspect of email phishing is the frequency with which scammers fall back on tried-and-true methods that really have no business working these days. Like attaching a phishing email to a traditional, clean email message, or leveraging link redirects on LinkedIn, or abusing an encoding method that makes it easy to disguise booby-trapped Microsoft Windows files as relatively harmless documents.

KrebsOnSecurity recently heard from a reader who was puzzled over an email he’d just received saying he needed to review and complete a supplied W-9 tax form. The missive was made to appear as if it were part of a mailbox delivery report from Microsoft 365 about messages that had failed to deliver.

The reader, who asked to remain anonymous, said the phishing message contained an attachment that appeared to have a file extension of “.pdf,” but something about it seemed off. For example, when he downloaded and tried to rename the file, the right arrow key on the keyboard moved his cursor to the left, and vice versa.

The file included in this phishing scam uses what’s known as a “right-to-left override” or RLO character. RLO is a special character within unicode — an encoding system that allows computers to exchange information regardless of the language used — that supports languages written from right to left, such as Arabic and Hebrew.

Look carefully at the screenshot below and you’ll notice that while Microsoft Windows says the file attached to the phishing message is named “lme.pdf,” the full filename is “fdp.eml” spelled backwards. In essence, this is a .eml file — an electronic mail format or email saved in plain text — masquerading as a .PDF file.

“The email came through Microsoft Office 365 with all the detections turned on and was not caught,” the reader continued. “When the same email is sent through Mimecast, Mimecast is smart enough to detect the encoding and it renames the attachment to ‘___fdp.eml.’ One would think Microsoft would have had plenty of time by now to address this.”

Indeed, KrebsOnSecurity first covered RLO-based phishing attacks back in 2011, and even then it wasn’t a new trick.

Opening the .eml file generates a rendering of a webpage that mimics an alert from Microsoft about wayward messages awaiting restoration to your inbox. Clicking on the “Restore Messages” link there bounces you through an open redirect on LinkedIn before forwarding to the phishing webpage.

As noted here last year, scammers have long taken advantage of a marketing feature on the business networking site which lets them create a LinkedIn.com link that bounces your browser to other websites, such as phishing pages that mimic top online brands (but chiefly Linkedin’s parent firm Microsoft).

The landing page after the LinkedIn redirect displays what appears to be an Office 365 login page, which is naturally a phishing website made to look like an official Microsoft Office property.

In summary, this phishing scam uses an old RLO trick to fool Microsoft Windows into thinking the attached file is something else, and when clicked the link uses an open redirect on a Microsoft-owned website (LinkedIn) to send people to a phishing page that spoofs Microsoft and tries to steal customer email credentials.

According to the latest figures from Check Point Software, Microsoft was by far the most impersonated brand for phishing scams in the second quarter of 2023, accounting for nearly 30 percent of all brand phishing attempts.

An unsolicited message that arrives with one of these .eml files as an attachment is more than likely to be a phishing lure. The best advice to sidestep phishing scams is to avoid clicking on links that arrive unbidden in emails, text messages and other mediums. Most phishing scams invoke a temporal element that warns of dire consequences should you fail to respond or act quickly.

If you’re unsure whether a message is legitimate, take a deep breath and visit the site or service in question manually — ideally, using a browser bookmark to avoid potential typosquatting sites.
