Issues with the PhishAlarm button? Clear your cache – 11/03/20

 

 

This week the phishing training program resumed.  This gave everyone a chance to use the new PhishAlarm button to report the suspicious emails.  For most of you, it worked great!. For some of you, not so much.

As the PhishAlarm button is a browser based tool  (it works through your web browser), it can act up when your browser acts up. This is true for all browser based tools. When this happens it can usually be remedied by clearing your cache.

Your cache is where images and content are downloaded and stored. Your browser does this to save time loading a web page. The first time you visit it, it will load some key information into your cache. The next time you visit that page, instead of downloading it from the internet again, it goes to the cache and loads it from there. This makes the webpage load much faster. This is true whether the page is a just a boring website or a web based application.

So the next time the PhishAlarm button gives you an error message or any other web based application gives you trouble, clear your cache.  It will empty all the information stored there and download it from the Internet again.  This basically resets the application and it usually starts working. For details on how to clear your cache, check your browser’s help files.

Happy Reporting!!

Hackers targeting educators – 11/04/20

 

 

There is a new phishing attack that is taking advantage of the widely acknowledged technology issues facing students, families, and educators. It is targeting educators, using infected attachments that masquerade as student assignments.  The attachments contain ransomware that encrypts your files and locks you out of your devices until the ransom is paid.

In this type of attack, the hackers pose as a parent or guardian submitting a student’s assignment on their behalf. They claim that the student was unable to upload the document due to technical issues. The emails are very emotional and are designed to tug on the heart strings of the educator.

The subject lines the attackers have been using are:
• Son’s Assignment Upload
• Assignment Upload Failure for [Name]
• [Name]’s Assignment Upload Failed

Here is an example of the types of emails being used.

 

Often the attachment is a Word document . Once you open it, you are asked to  “enable editing” and “enable content”. If you do, the ransomware is loaded onto your device.

This attack is very targeted, using contact lists available on the school’s websites to determine who to send emails to. Although the attackers are currently focusing on K through 12 schools, it is expected it will move to post secondary institutions next.

To avoid these types of attacks:

  • Only accept assignments submitted through regular channels.
  • Do not open an attachment unless you check the sender’s email address and know who the email is coming from.
  • Verify the sender actually sent the message whenever possible.
  • Do not enable content or editing on Word documents unless you are 100% certain of the sender’s identity.
  • Do not enable macros on Word or Excel documents unless you have talked to the sender of the email to verify it is safe to do so.

If you are unable to contact the sender and aren’t sure of the legitimacy of an email, report is using the PhishAlarm button or by forwarding it to cybersecurity@mtroyal.ca.

 

Don’t take candy from strangers – 09/16/20

All malware is not created equal.  This week a particularly devious piece landed in an MRU inbox.  It was wrapped up in a zip file attachment. Here is what the malicious email looked like:

 

 

This malicious email is hard to identify as it contains a previously sent email thread. Interestingly enough, there is no human behind this email. It was sent by malware. When it gets on your machine it picks an email in your inbox and replies to it. Sending a copy of itself to an unsuspecting recipient.

The email is generic enough to work with pretty much any email. However it is the vagueness that flags it as suspicious.  The other tell is the sender’s email address. Because this is malware and not a person sending out the email, the sender’s email address is incorrect.

If you decide to click and open the attachment, you see an Excel spreadsheet with this in the first cell.

 

 

If you missed the other two red flags, this one is your last chance to dodge the bullet. This very official looking graphic is asking you to enable editing and content to be able to “decrypt” the document  It is also telling you what type of device to use to view it.  Anytime you have this kind of instruction given to you to view a document, close it immediately and report it.

The instructions are not there to enable you to view the document. They are there to ensure the malware can be installed and will function.  By asking you to enable editing and content, it is bypassing the safety controls we have in place to prevent the running of macros. It is not “decrypting” anything.  If you can’t open a document just by clicking on it, consider it a threat.

This is another reminder how important it is to check the sender’s email address before you open an attachment or click on a link.  If you recognize it, contact the sender using another method and confirm that they sent the email. If you don’t recognize it, don’t click. You wouldn’t take candy from a stranger, you shouldn’t take attachments from them either;  no matter how enticing they are.

 

 

Sneaky fake evaluation form found in MRU inboxes – 06/05/20

With the Phish Bowl up and running I don’t do many posts about phishing emails any more.  However one showed up on campus this week that provides such a great teaching opportunity, that I had to write about it.

Here is the offender:

 

 

To make things even more confusing, the email links to a legitimate Google Form. Clicking on the Fill Out Form button, does indeed take you to a Google form.  Nothing malicious is loaded onto your machine and the form looks like a completely legitimate evaluation form, with one exception.  It asks for your Microsoft ID and password.

Any time any form asks you for a password, no matter how legitimate it looks, exit the form immediately. If you do enter your credentials and then realize that you shouldn’t , change them immediately.

 

Hackers use fake Cisco WebEx vulnerability to lure victims – 05/21/20

Criminals are sending phishing emails that look surprisingly legitimate. They appear to come from apparently trustworthy senders, like “cisco@webex[.]com” and “meetings@webex[.]com.” They emails urge recipients to take an immediate action in order to fix a security vulnerability in their WebEx software. The emails look like this:

 

 

If you click on the Join button, it will take you to a page that asks for your login credentials. Of course the login page belongs to the criminals and will only steal your credentials.

If you receive an email asking you to update software, do not click the links in the email. Instead, start up the software and check for updates by selecting Help from its menu and selecting About. You can also visit the official website for the software and load updates from there.

 

Criminals are creating look-a-like MRU webpages – 04/23/20

 

We have been notified that cybercriminals have registered and are using the domain www.mroyalu.ca as well as several other look-a-like domains. They are attempting to fool people into visiting their malicious websites.

While working from home, it is very important that you double check all links that you receive in emails and the sender’s email address.

If the link does not have mtroyal.ca, mru.ca, mrucougars.com or mymru.ca before the first single / in the URL, it is malicious.

Examples of legitimate URLs are:
mru.ca/cybersecurity
mru.ca/wellness
https://www.mtroyal.ca/AboutMountRoyal/WhyMRU/
https://www.mymru.ca/web/home-community

Examples of fraudulent URLs are:
https://www.mroyalu.ca/AboutMountRoyal/WhyMRU/
https://www.mymur.ca/web/home-community
https://www.my.mtroyal.ca/Home
Please do not let curiosity get the better of you, and attempt to visit any of these fraudulent websites. They will harm your machine and/or steal your data.

If the sender’s email address ends in anything other than @mtroyal.ca, then it is malicious.

Examples of legitimate email addresses are:
bpasteris@mtroyal.ca
cybersecurity@mtroyal.ca

Examples of fraudulent email addresses are:
bpasteris.mtroyal.ca@gmail.com
bpasteris@mroyalu.ca
bpasteris@mtroyal.email.ca

Please be extra cautious at this time.

Credit Registration stops a cybercriminal – 04/15/20

Every once in a while I get affirmation that all that I do to try and keep all of you safe is working. This was one of those weeks. I would like to take a moment to toot the horn of Credit Registration.

They receive hundreds of emails from students and prospective students every week. The majority of the time they have no idea who they are talking to.  To reduce the chances they will be cyberattack victims, they have put procedures into place that somewhat verify the sender’s identity. It isn’t fool proof, but it is a good balance between practicality and security. What is truly wonderful is their staff follow their procedures.

This week those procedures were tested and they passed.  Congratulations Credit Registration!

No, that isn’t your supervisor asking for your cell phone number – 04/09/20

 

This week has been a busy one for the security team. We have been slammed with a new phishing tactic, requests for cell phone numbers.  Campus inboxes are receiving emails that appear to be coming from a supervisor. They look like this.

 

 

While this one contains a misspelled word, others look perfectly legit. The only clue is the  weird sender email address.

Why do they want your cell phone number? Lots of reasons. First of all they can take your phone number and connect it to your email address which helps build out your data profile so advertisers can more easily target you with ads. Advertisers pay a premium for complete data profiles.

But the benefits don’t stop there. If they have your phone number, know where you work, have an email address and your name, they have enough information to impersonate you with your cell phone provider.  If the customer service agent that answers the call doesn’t follow proper procedures, the scammer can port your number to a different carrier or disable your SIM card and get a new one. Either way you lose control of your phone number and the criminal now has access to everything that uses your phone number for confirmation.  One MRU employee has already found out how damaging this type of attack can be.

Lastly they can send you lovely text messages containing links that appear to come from your bank, include offers for free stuff or opportunities to enter a contest. Clicking on these links load malware onto your device designed to steal passwords, contacts and data.

Your best defense against this type of attack, is to read the sender’s email address before you read the body of the message. If you see that the email is not from a Mount Royal account, you can delete the message before your emotions are triggered by the email content.

If you aren’t sure if an email is legit, you can check the Phish Bowl to see if it is listed there or you can forward the email to abuse@mtroyal.ca. If you find a phishing email, don’t forget to report it by clicking the PhishAlarm button or forwarding it to cybersecurity@mtroyal.ca so we can warn your colleagues.

Coronavirus based attacks are rampant – 03/19/20

 

As employees all over the world are working from home,  criminals are ramping things up hoping to take advantage of the less secure networks that people tend to have at home. We have surges in phishing emails on campus and across the world related to working from home as well as an increase in malicious websites.  It has gotten so bad the US Secret Service has issued a warning. Here are some things to watch out for.

The fake VPN

As employees struggle to setup a home office, they are signing up and downloading VPN services at record rates. While all of our employees have the advantage of using SRAS, many smaller organizations do not have their own VPN tool and are asking employees to install one on their home computer. If your spouse or roommate are in this situation, warn them to be very careful about what VPN they download. Cyberattackers are offering fake VPN services that download malware onto your machine in record numbers. Make sure they check reviews of the service to ensure it is reputable before they install it on their machine.

Fake COVID-19 trackers

As people attempt to live their lives and stay safe, many are turning to maps that track the location and incidence of infections. Criminals are getting wise and creating their own versions of these tracking websites that infect your computer with malware.

Some enterprising scammers have also created phone apps that supposedly track the infection rate  but load your device with ransomware instead. Stick to well known and reputable websites such as Alberta Health Services and the World Health Organization to get your information about the virus and stay away from any apps related to it including ones that tell you how to get rid of it.

Phishing emails about working from home and COVID-19

Phishing email attacks are off the scale. Everything from fake emails from your organization about working from home, to offers of vaccines and cures.  One of their favorites is fake GoFundMe pages with coronavirus victims pleading for medical help.   Another is pretending to be a colleague who is quarantined and needs help.

You name it, the depraved are going to try it. During this time it is especially important to be vigilant. If you receive an email that doesn’t come from a Mount Royal email address, question its validity. While you are working at home, make sure you use your Mount Royal email address to send business correspondence. DO NOT use your personal email address. This will make it easier for your colleagues to stay safe.

If you don’t report, we don’t know – 03/17/20

 

 

With the world on melt down, cyberattackers took advantage of the mayhem to send out a slew of spear phishing emails to several departments. Most of them had a member who reported the suspicious email right away. As a result, we were able to notify their colleagues before most of them had even opened it.

Unfortunately, one department was left vulnerable. None of their members reported the malicious email sent to them. We eventually found it, but we it was much later and there was a delay in the notification going out.  This delay increased the chances that someone would become a cyberattack victim.

We know that all of you have much on your mind trying to figure out how to teach and work from home. However during this challenging time, please don’t forget to take those extra two seconds to let us know when something suspicious lands in your inbox. The sooner we know, the sooner we can let everyone else know and reduce the risks to everyone’s data, including yours.
