Phishing email with subject: “ DO NOT IGNORE THE WARNING”

Thursday, March 15th, 2018

Several staff are receiving a “threatening” e-mail with the subject “<your email address> DO NOT IGNORE THE WARNING”

Your e-mail address will be inserted at the begining of the message, and then proceeds to inform you about your account being used for “spam activities” and that it will be blacklisted and permanently suspended.

Here is an example of the mail (with all the dangerous stuff removed)

If you are fooled into clicking on the link, you will be taken to a website (based in Zimbabwe) and your e-mail address will be automatically inserted in the field, and you will be asked to type in your password, and then the scammers will have gained access to your network account!

This is a typical tactic employed by phishers targeting university e-mail accounts. They use your contact details and intimidating language to cause you to panic and “click on the link they provide.

When spotting phishing scams remember:

  1. Don’t trust the display name.
  2. Look but don’t click.
  3. Check for spelling mistakes.
  4. Analyse the salutation.
  5. Don’t give up personal information – ever.
  6. Beware of urgent or threatening language in the subject line.
  7. Review the signature (remember the university’s own centennial celebration and “water-wise” branding is being used in *some* external phishing attacks)
  8. Don’t click on attachments.
  9. Don’t trust the header from an email address.
  10. Don’t believe everything you see.

Phishers are extremely good at what they do. Just because an email has convincing brand logos, language, and a seemingly valid email address, does not mean that it’s legitimate. Be sceptical when it comes to your email messages—if it looks even remotely suspicious, don’t open it.

If you have received mail that looks like this, please immediately report it to the Information Technology Security Team using the following method:

Send the spam/phishing mail to the following addresses: help@sun.ac.za and sysadm@sun.ac.za

Attach the phishing or suspicious mail on to the message if possible.  

  1. Start up a new mail addressed to sysadm@sun.ac.za (CC: help@sun.ac.za)
  2. Use the Title “SPAM” (without quotes) in the Subject.
  3. With this New Mail window open, drag the suspicious spam/phishing mail from your Inbox into the New Mail Window. It will attach the mail as an enclosure and a small icon with a light yellow envelope will appear in the attachments section of the New Mail.
  4. Send the mail.

Phishing scam about reaching your mailbox storage limit

Tuesday, March 6th, 2018

Monday started with a phishing scam threatening to close your mailbox, and Monday is ending with another attack, using a similar intimidation tactic about your mailbox size.

The grammar and spelling is very poor on this one so it should be rather easy to spot. However the use of University branding and “STELLENBOSCH HELP DESK” might fool some people.


The Subject will be “We apologies” (sic)

Dear User,

You have reached the storage limit for your mailbox. Please visit the following link to complete your e-mail access restore.

Follow this link to complete the process: Click Restore

STELLENBOSCH HELP DESK


If you do click on the link (which does not go to a university website) …this webpage will appear. 

 

 

Many thanks to all of you who reported this.

Remember these 5 guidelines:

  1. Information Technology will never request sensitive information such as passwords.
  2. Phishing e-mails often appear as an important notice or urgent matter such as threats that your mailbox is over quota.
  3. Use of aggressive or intimidating language such as ‘immediately’ and threats of consequences of not verifying your account.
  4. Misspelled words and poor grammar that take away from the professional context of the e-mail. (this one is quite obvious)
  5. Use of an impersonal greeting. (Dear User)

If you have received mail that looks like this please immediately report it to the Information Technology Security Team using the following method:

Send the spam/phishing mail to help@sun.ac.za  and sysadm@sun.ac.za

 Attach the phishing or suspicious mail on to the message if possible. There is a good tutorial on how to do this at the following link (Which is safe) : http://stbsp01.stb.sun.ac.za/innov/it/it-help/Wiki%20Pages/Spam%20sysadmin%20Eng.aspx

  1. Start up a new mail addressed to sysadm@sun.ac.za (CC: help@sun.ac.za)
  2. Use the Title “SPAM” (without quotes) in the Subject.
  3. With this New Mail window open, drag the suspicious spam/phishing mail from your Inbox into the New Mail Window. It will attach the mail as an enclosure and a small icon with a light yellow envelope will appear in the attachments section of the New Mail.
  4. Send the mail.

IF YOU HAVE FALLEN FOR THE SCAM:

If you did click on the link of this phishing spam and unwittingly give the scammers your username, e-mail address and password you should immediately go to http://www.sun.ac.za/useradm and change the passwords on ALL your university accounts (making sure the new password is completely different, and is a strong password that will not be easily guessed.) as well as changing the passwords on your social media and private e-mail accounts (especially if you use the same passwords on these accounts.)

Windows updates: for your own safety

Monday, February 26th, 2018

Due to the increasing threat of cybercrime and in an attempt to strengthen the security of our campus devices and network, Information Technology will be performing regular scans of devices on the network to identify possible weaknesses. These scans will be done after hours and will have no impact on your work during the day.

If a device presenting a potential threat is identified, a request will be logged on ServiceNow, Information Technology’s call logging system. One of our IT representatives will then contact the user of the device to establish whether the device is up to date with the latest Windows updates, antivirus updates and if the software is up to date. 

Do not be alarmed when an IT representative calls you and asks to update your SU work device. This process is for your own benefit and will not only protect our network, but also your device and your data.

We would appreciate it if you could assist us with safeguarding our network by regularly installing Windows updates and restarting your device after the updates in order to apply the updates. 

We are also attempting to upgrade PCs with Windows 10 v1511 to the latest version – Windows 10 v1709. To find out which version of Windows 10 your PC is running, press Windows logo key + R, type winver, then select OK.

If you would like to upgrade your PC, please send an e-mail to the IT Service Desk at help@sun.ac.za to log a request.

Dropbox phishing scam

Monday, February 5th, 2018

If you receive an email from your bank wanting to share a paper via Dropbox with you, be aware that it’s a phishing scam. 

If you hover your mouse (don’t click on the Dropbox link) over the link the originating server will appear and it is NOT DropBox, but the phisher’s server, currently based in Brazil. No bank would ever use DropBox to send you documents.

This e-mail has some obvious signs of a phishing scam. First, it does not address you personally, but uses your email address. Also, the email sounds urgent, (it from “your bank”) trying to get you to react quickly without thinking and click on the button. Finally, if you hover over the button, your browser will display the link destination (what is called the spammy URL) at the bottom of the window. The URL does not belong to the alleged sender, Dropbox.

Victims who are fooled into clicking on the link will get the following webpage:

 

(Notice the links to Outlook Mail and the name of the server that is not Dropbox’s servers but one based in Brazil.)

These criminals want you to divulge your personal details like usernames, passwords etc.

If you have received emails similar to this please  report it to the Information Technology Security Team using the following method:

Send the spam/phishing mail to help@sun.ac.za and sysadm@sun.ac.za.

 Attach the phishing or suspicious mail on to the message if possible. There is a good tutorial on how to do this at the following link (Which is safe) : http://stbsp01.stb.sun.ac.za/innov/it/it-help/Wiki%20Pages/Spam%20sysadmin%20Eng.aspx

Virus warning

Monday, February 5th, 2018

If you receive an email with the subject: “URGENT – CCMA Final Reminder: Case GAJK0238819-18 (GAJK) is scheduled for ‘Arbitration’…” allegedly sent by the CCMA, and with an attachment with a .DOC.gz extension, DO NOT try to open it. The attachment is a rather nasty Trojan-variant of a Crypto virus.

This virus opens the “back door” of your computer to hackers once it infects your PC. The trojan is programmed to run at every start-up, giving the hackers, who originated the program, access to your hard drive. In addition, this trojan can re-create itself, making it hard to remove it completely.

If you received this email or any similar ones, please it to the Information Technology Security Team using the following method:

Send the spam/phishing mail to help@sun.ac.za and sysadm@sun.ac.za

Attach the phishing or suspicious mail on to the message if possible. There is a good tutorial on how to do this at the following link (Which is safe) : http://stbsp01.stb.sun.ac.za/innov/it/it-help/Wiki%20Pages/Spam%20sysadmin%20Eng.aspx

  2. Use the Title “SPAM” (without quotes) in the Subject.
  3. With this New Mail window open, drag the suspicious spam/phishing mail from your Inbox into the New Mail Window. It will attach the mail as an enclosure and a small icon with a light yellow envelope will appear in the attachments section of the New Mail.
  4. Send the mail.
