Phishing scam targeting Apple users

Thursday, December 7th, 2017

If you are the owner of an Apple product like an iPhone, iPad or MacBook and have an AppleID, then please be aware of a phishing scam currently making the rounds. It targets university personnel (using university usernames – including student numbers)

The subject lines will be “Account Suspension Notification” or “Account Activity Notification” and will tell you that because AppleID account has been logged in from “multiple locations and different countries” your account has been suspended, and you need to log in using your AppleID to reactivate your account on Apple.

Now, if you don’t have an Apple product, this would be something to ignore and spot as a phishing scam, but if you do have an Apple product you might *panic* and click on the link.

This is exactly what the scammers want you to do. You would be taken to a forged website that looks like the Apple Login page and asked to type in your Apple ID username and password. That is what the scammers are after! They can then access your real AppleID account and steal information, credit cards details etc.

  1. Don’t open links inside emails, especially if you’re not 100% sure who sent it.
  2. if you’re about to click on a link from a company as reputable as Apple, It will always have a customer service department you can contact. You can ask if Apple has sent you a link requesting updated contact information. Or better yet, log into your Apple account; click on the Manage My Apple ID tab, to make sure your information is up to date.
  3. Ensure you have up-to-date antivirus and malware/anti-phishing software installed on your computer.

Spear-phishing scam from “university personnel”

Wednesday, December 6th, 2017

Spear-phishing is a targeted form of phishing in which fraudulent emails are sent to specific individuals at an institution, like the university, in an effort to gain access to confidential information.

This morning we are starting to see the spear-phishing scam emails being sent out in the name of known individuals at the university – in Tygerberg’s case – the Dean, Prof Jimmy Volmink.

Below is a mail that is being sent out “in the name” of Prof Volmink, entitled “Invoice Problem”. (click on image to enlarge) It was sent to several university addresses, uses a forged e-mail address from another university, and has been designed to convince people that it is legitimate.

This is a dangerous phishing scam because it seems to come from a known person.Do not respond to it and if you do receive it here is what to do:

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. 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 for these accounts.)

IT has set up a website page with useful information on how to report and combat phishing and spam. The address is:

https://blogs.sun.ac.za/it/en/2017/11/reporting-spam-malware-and-phishing/

As you can see the address has a sun.ac.za at the end of the domain name, so it is legitimate. I suggest bookmarking this.

Phishing attack with subject: “Re-Validate”

Saturday, December 2nd, 2017

With the graduation just around the corner and most students already on holiday, and many of our colleagues already taking a well-deserved break, and collectively we all tend to be a little less vigilant.

The end of the year vacation period is generally a time when phishing attacks on our email accounts drop, and it is speculated that the phishers know there are significantly fewer employees working during the holidays, so there are fewer opportunities for targeted users to actually open malicious attachments.

However spear-phishing attacks increase when the Information technology and “cyber-security”  centres of large enterprises like the university security operations are lightly staffed or understaffed. The scammers know that there is a greater chance for them to gain access to accounts via spear-phishing as the “watchdogs” are fewer.

What is spear-phishing?

Spear-phishing is a targeted form of phishing in which fraudulent emails are sent to specific individuals at an institution like the university in an effort to gain access to confidential information. Often a trustworthy entity is impersonated that uses “urgent” language to requesting sensitive information or actions.

[In August this year the MacEwan University in Canada was targeted when a series of fraudulent emails convinced MacEwan University staff to change electronic banking information for one of the university’s major vendors, resulting in $11.8 million being transferred to criminals.]

The following spear-phishing e-mail is appearing in some student and personnel accounts and it seems to be targeting university accounts specifically as the salutation is a personal name: (in this case your e-mail address, or in some cases your display name in e-mail e.g Wiles, David <dw@sun.ac.za>

The mail will look like this:

~~~

From: Zimbra <infog@adm.orel.ru>
Sent: 01 December 2017 22:15
To: Your Own name <your-e-mail@sun.ac.za>
Subject: Re-Validate

 
Dear your-e-mail@sun.ac.za , 
Your account has exceeded it quota limit as set by Administrator, and you may not be able to send or receive new mails until you Re-Validate your your-e-mail@sun.ac.za account. 
To Re-Validate account@sun.ac.za account, Please CLICK: Re-Validate your-e-mail@sun.ac.za Account
 
~~~
 
If you click on the link you will be taken to a website that will show the following login window where you will be asked to fill in your personal details and password. Once this happen the spear-phishers will have gained control over your email account and will proceed to locate more sensitive information like other e-mail addresses and bank account details, for example. Your e-mail account will then be used to attack other university accounts.


Please be aware of this spear-phishing scam. No university department or division will ever ask you for passwords via e-mail.

Nigerian 419 Advance Fee scam

Wednesday, November 29th, 2017

A scam in the form of a well-known “Nigerian 419 Advance Fee” mail is appearing in some of our colleagues and students mailboxes this morning.

The mail is rather simple:

Subject is: “Kindly view attach and forward your reply to <a gmail address>”

The mail’s content simply states the same and the attachment is an image of a letter and states that the sender has a large amount of money that they would like to send you.

This is a typical “Nigerian 411 Advance Fee” scam.

Here is how it works:

You receive an unsolicited message that masquerades as some manner of business proposition, request for assistance, notice of a potential inheritance, or opportunity to help a charity but all of the scam messages share a common theme.

The messages all claim that your help is needed to access a very large sum of money and promise that you will receive a significant portion of this money in exchange for your help.

The scammers use a variety of stories to explain why they need your help to access the funds.

  • They may claim that political climate or legal issues preclude them from accessing funds in a foreign bank account and request your help to gain such access.
  • They may claim that your last name is the same as that of the deceased person who owned an account and suggests that you act as the next of kin of this person in order to gain access to the account’s funds.
  • They may claim that a rich businessman, who has a terminal illness, needs your help to distribute his wealth to charity.
  • They may claim that a soldier stationed overseas has discovered a cache of hidden cash left by a fleeing dictator and needs your help to get the money out of the country.

All these scams promise to let you keep a significant percentage of the funds in exchange for your assistance. This is the bait that is used to pull potential victims deeper into the scam. Once a recipient has taken the bait, and initiated a dialogue with the scammers, he or she will soon receive requests for “fees” that the scammer claims are necessary for processing costs, tax and legal fees, bribes to local officials, or other – totally imaginary – fees.

In reality, the supposed funds do not exist and the main purpose of these scam messages is to trick recipients into parting with their money in the form of these advance fees. Fraudulent requests for fees will usually continue until the victim realises he or she is being conned and stops sending money. In some cases, the scammers may gather enough information to access the victim’s bank account directly or steal the victim’s identity.

Typically, advance fee scammers will send many thousands of identical scam messages to recipients all around the world. (as is today’s example) It only takes a few recipients to fall for the claims in the messages to make the operation pay off for the criminals.

What to do if you receive such an Advance Fee email:

It is important that you do not respond to it in any way. The scammers are likely to act upon any response from those they see as potential victims. The best thing to do with these scam messages is to simply delete them.

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. 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.

Phishing: Subject “Your Email Address Has Been Compromised”

Wednesday, November 15th, 2017

We’ve had a couple of reports from personnel and students about getting messages with a subject of “Your Email Address Has Been Compromised” (notice the capitalisation of every word, which is one of the signs of phishing)

The scammers have spoofed the recipient (your e-mail address to read info@verify.com) and the sender seems to come from a compromised university account in the USA (address end with an .edu)

The subject says: “Your Email Address Has Been Compromised” and a link Verify HERE is included which takes you to a website ending with a “weebly.com”. It looks already as if the website is offline or has already been blocked by Information Technology, but you should never click on links in mail if the sender is unknown.

Keep in mind, Information Technology will never send you such a mail, telling you that your e-mail address has been compromised. All IT’s communications are bilingual and will always address you personally.

If you get mail like this and you are not sure if it is legitimate or not, you should never click links or respond but rather contact IT telephonically at 808 4367 to verify. 

Information Technology will send you an automated mail IF you have changed your password on the network that is branded, is bilingual, and informs you of a password change, but it is always better to check and make sure especially if you HAVEN’T changed your password or don’t recall if you have changed your password.

Here is an example of the current phishing scam.

 

 

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 as well.

 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 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.)
