Cisco has released an update to their Jabber for Windows application. This update fixes a critical vulnerability that would allow an attacker to potentially execute arbitrary code on your computer without requiring any action on your part while the application was running in the background.
If you use Jabber for Windows please update it immediately. The Jabber for Windows update can be downloaded here. Enter your MRU login credentials when prompted to gain access to the download. Although Jabber for Mac has not been effected, it is still a good idea to keep it updated. The latest version can be downloaded here.
If you are only using Jabber on your iphone or Android smartphone, you are not affected by this vulnerability. For more details, read the Latest Hacking News article.
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.
In September last year, the first of several targeted email scams arrived in Mount Royal inboxes. Since that time we have see a plethora of these scams spread across campus. Up to now that have all been emails from a supervisor asking a report to do a favor for them.
However, we must have ended up on some “the Best People to Scam” list as this week the scams have gotten very creative. First up is a dude in Indonesia contacting Wellness Services to help him sell a helicopter (I actually think this might be legit). Second up is an email to the MRFA insisting a charge from their store has appeared on a bank statement (definitely not legit). Check out the pics!!
As entertaining as these emails are, that is not the reason why I am sharing them with you (well maybe a little bit). I am sharing them to give you a heads ups that MRU is being actively targeted and we all need to be on our toes. If you receive any email that is out of the ordinary, please take a closer look at it. If you aren’t sure if it is malicious, forward it to firstname.lastname@example.org like your colleagues did and we can take a look. Everyone who reports an email gets a cool sticker. Be a superhero and report those malicious emails!
Another day, another clever criminal trying to break into our network. This time they tried using the Google Drive to do it. Tuesday morning several employees found this in their inbox.
The Word Doc link is totally legit. If you click the link, it takes you to this document.
Clicking the link in the Word document takes you to a legitimate website that has been compromised. The site asks you to login to Office 360 to access the document. Of course if you do, you are giving some miscreant your Office 360 login credentials. They can then sell your credentials on the dark web or use them themselves to wreak havoc on your data as well as the data of others. Fun, Fun, Fun.
Because the Google Drive file share and the website are legitimate, they won’t be flagged by anti-virus or the firewall. It is actually very clever. However although it may get by the technology, a person can easily spot this as malicious. In fact, we had two different reports sent to email@example.com about this one. Way to go MRU!!
For those of you who aren’t already yelling at the screen, “Come on, that is so obvious”, I am going to walk you through the red flags. First one is the email is sent by Benjamin Kuiper from the email address firstname.lastname@example.org. Clearly not a Mount Royal email and he is not listed in the directory. Fail number one.
Second, the doc says it was being shared by Benjamin and David Hyttenrauch. This doc was sent to people on David’s team so even though they didn’t know who Ben was, they sure as heck knew who David was. This got the desired attention. However, you can’t send an invite to share one file from two people. Clearly, this Word doc was shared by Benjamin and the sneaky dude entered the rest of the deceiving information into the Add a note field in the Share with others dialog box to make it looks like Dave was involved. Fail number two.
Third, when you open the document it tells you that you have a file waiting for you on the OneDrive. OneDrive file shares are not sent with links in Word documents. Fail number three.
Lastly, if you were to hover over the link in the Word document you would see that it does not go to OneDrive. Fail number four.
As clever as criminals are, most of them can be stopped by alert employees who take the time to look at emails with links and attachments critically. As we have seen in this example, the majority of the time phishing emails contain clear clues that something is not right. Don’t get caught up in the emotion of the moment. Like our wonderful employees, take the time to really look and make sure that the email is what it appears to be. Your data, your colleagues and your IT department will thank you.
Today Facebook announced that they have discovered hackers have stolen 50 million access tokens. These tokens allow them to take over an account without having to login with a password. They did it by taking advantage of a vulnerability in the View As feature that allows users to see what their account looks like when viewed by others.
To solve the problem, they have logged out all the users who they believe were affected and disabled the View As feature. As often happens in these types of breaches, there is a possibility that at a later date they may find there are more people affected than originally thought.
To be on the safe side I suggest that you logout of Facebook by going to Settings and selecting Security and Login. There you can logout of all your devices at once with a single click. Alternatively, this might be a good time to get rid of Facebook all together.
It has been a busy week. There are two phishing emails going around campus at the moment. The first one starts out rather innocently.
However if you respond to it, like half a dozen people did, you receive a second one.
You are probably wondering why anyone would respond to the first email. First of all the email was from a department head, so that tends to get people’s attention and generate an emotional response. Also, almost all who responded were looking at the email message on their phone. They were unable to clearly see the sender’s email address or the grammar errors. This is just another reminder as to why it is so important to wait until you get to a large screen to take action on an email. It is also a reminder to not respond to our emotions. If you read an email and are responding emotionally to it, that is your cue to pause for a minute and take a closer look.
Impersonator number two is a bit more sneaky. Check out this bad boy.
I just love how they added the signature line to this one. They must have received an email from Mount Royal at some point. This is the stuff that keeps me up at night. The grammar is perfect. The content is plausible and looks legitimate. The fuzzy logo is a bit of a tell, but other than that it’s not an easy one to spot.
That was the bad news. Now for the good news. In both cases IT services was notified of the threat by Mount Royal University employees who forwarded the email to email@example.com. Their quick thinking gave us a heads up right away so we could block both email addresses and prevent further attacks. They are superheros!!
Keep an eye out for these types of emails in the future. If you find one, forward it in its entirety (no screenshots please) to firstname.lastname@example.org and you can be a superhero to!!
A college that we communicate with regularly has had one of their email accounts compromised. As a result, several people around campus have received emails with requests to Download Attachments from Sharefile. The emails look like this:
The name of the college and the email sender have been blurred out to protect their privacy.
What makes these emails so devious is that they come from someone that Mount Royal staff have been conversing with recently. This makes it much more challenging to identify them as malicious.
This is a gentle reminder to everyone to contact the email sender when you receive an unexpected email with a link or attachment using a contact number that you have used in the past or have found through Google. Even if you have been speaking with them recently if you aren’t expecting the email, call to confirm its legitimacy. Just because an email looks like it comes from someone you know, doesn’t mean it does.
That is what our brave Mount Royal employee did and as a result prevented a potentially serious cyber security incident. Had they simply clicked on the Download Attachments button and followed the instructions, they would have given the hacker their Docusign credentials. Who knows what that would have led to.
Mount Royal employees are receiving emails from a vendor that are actually replies to a legitimate message. As the message is a reply and it is from someone we do business with, employees have been tricked into opening the attachment more than once putting our network at risk.
How the heck did they manage to reply to a message that the vendor had sent ages ago? Simple, the vendors email account was hacked. Once the hackers had access to the email account all they had to do was scroll through the emails in the sent folder until they found one that mentions an invoice and reply to it. Of course they attached an edited invoice containing a nice little keylogger trojan onto it first.
Those that opened the attachment found a blank document and then contacted the Service Desk to see why. The Service Desk calmly explained all their keystrokes were being recorded by malware they had unintentionally installed and then sent support staff to re-image (wipe clean and re-install) their machines.
Unfortunately this is not the first time that Mount Royal University has been targeted by this type of attack. Late last year another vendor had their email account compromised and multiple Mount Royal staff members received replies to an old meeting invite containing a document that “required their input”. That document contained malware as well and once again we were re-imaging machines.
How do you know when an email from a vendor contains a malicious link or attachment? Truthfully, you don’t. The only red flag on either of these emails was the date of the original message. The email thread was months old and was used in the attack because it contained a subject that would allow an attachment to be added to it without looking odd. However, a recent message could also have been used if it had contained the right content.
So how do you protect yourself from such attacks? You call the vendor when you receive an email with a link or attachment and confirm that they sent the email. You do not reply to the email as if their email account has been compromised, you will be conversing with the hacker. Do not use the contact information found in the email to contact the vendor either. The hacker may have changed the email signature. Use a contact number that you find in a Google search or that you have used before.
Yes, horrors, you have to actually pick up the phone and talk to a person. However, it will practically eliminate the risk of having your machine wiped clean and the operating system re-installed. Not a fun way to spend the morning.
One sure sign that spring is on its way…tax scammers pop up along with the tulips. Although we are a ways away from enjoying the tulips, the scammers are out in full force. One Mount Royal employee came into work to find this on his voicemail.
Click the far left of the bar to listen to the voicemail message.
Pretty nasty huh? So how to do you know this is a scam? Simple, the CRA will never phone you and threaten legal action or arrest. They will never send someone to your house to collect payment or to arrest you either. This was a voicemail, so it was easy to calmly listen to the message and analyze it to determine if it was legitimate.
What do you do if they have you on the phone and they are threatening you? The scammers can be very insistent and believable causing considerable stress and confusion. If you experience a call like that from the CRA, tell them you will call them back and hang up. You can then contact the CRA at 1-800-959-8281. If there are any issues with your taxes, whoever answers the phone will be able to address them.
Watch out for phishing emails from the CRA as well. As I mentioned in a post last year, the CRA will never email you unless you have given them previous permission to do so and they will never send you an email with links unless you have specifically requested a document.
Yesterday one of our staff members checked her voicemail and found a nasty message from an “Officer” Robert William asking her or her attorney to call him immediately before “the legal situation unfolds”. Our quick thinking staff member Googled the number, 905-581-1528 and discovered that it was a phone scam.
Had she called them, she would have been asked her personal information including her SIN. Armed with that info, the crooks would have applied for credit cards and loans in her name, leaving her on the hook for the payments. Only after months of paperwork and expensive legal fees would she have been able to clear her credit record and name.
This is just a reminder to never give out information people already should have, over the phone, in an email or text. If someone calls you and tells you they are from your bank, a vendor, the CRA, RCMP or Calgary Police Service:
- Ask for their name.
- Tell them you will call them back.
- Call the organization’s switchboard directly using a number that you obtain from a Google search or that you have used before.
- Ask for the individual by name.
If they insist that the only way to reach them is through a number that they give you, you know that it is not a legitimate call. If they tell you that they may not be available when you call back, you should be able to have your account or file reviewed by someone else in the same department.
Remember, no legitimate agency threatens legal action over the phone.
