Scam: Cancellation Of Debit Order (Absa)

Monday, October 29th, 2012

Please note the following phishing scam: These scams are becoming far more fine-tuned to South African victims and especially university accounts. Earlier this month there was a specific scam using Alexander-Forbes as a means to attack, Alexander-Forbes being the university’s preferred consultant for insurance, medical aid consultancy etc. Barely a week later Virgin Active’s name was used to attempt to scam university personnel. This week it is the turn of Outsurance. The e-mails are virtually identical, only the names and the servers in the background change, but you should be able to see that they are homing more and more to South African users, which tells me one thing that either they are getting this information from South African victims or these scamming operations are South-African based.   Here is an expurgated version of the scam. Please take note and be very careful!  From: Absa [mailto:ibt@onlinedata.co.za] Sent: 29 October 2012 01:46 PM To: Name <university_email@address.goes.here> Subject: Cancellation Of Debit Order(Absa) Dear Customer, We received a Debit Order alert on your account this morning from Outsurance Insurance Company to deduct the sum of R3150.00 from your account.

What is ransomware?

Friday, October 12th, 2012

The term ransomware will leave most people flabbergasted. How can software hold something ransom or is technology becoming so clever it can take over anything?

However, this description isn’t as far-fetched as it seems. Ransomware forms part of a group of malicious computer software called malware,  which cunningly installs itself on your pc and then has t he audacity to demand data or money from you. This type of programme can be installed by means of an e-mail attachment, an infected programme or unsafe website with malware installed on it. Ransomware” is also known as a a cryptoviruscryptotrojan or cryptoworm.

The software indeed “kidnaps” your data by encrypting or limiting your access to it and then sending you a message demanding money to regain your access.  The only way access is possible again, is by acquiring an encryption key from the creator of the ransomware at a fee.

A more recent version of the software will not notify the user that ransomware has been installed, but will merely block all access to the data and depend on the victim to search the internet for information on their “problem”. This search will then lead them to legit websites selling software to remove the ransomware, which of course is sold by the creator of the original culprit.

Ransomware is nothing new. In 1996 security experts at Columbia University and IBM wrote an essay called “Cryptovirology: Extortion-Based Security Threats and Countermeasures” to describe the software. At that time businesses were the main targets of ransomware and not individuals.

In March 2006 ransomware called Crypzip of Zippo was sent to a group of internet users. Those who received the programme also received an e-mail demanding a ransom of $300 if they wanted to access their data again.

Most antivirus vendors have ways of detecting and blocking the most known ransomware. However, no data is 100% safe. To ensure you don’t find yourself in this tricky situation, try to back up data regularly, be cautious when browsing the internet and under no circumstances open e-mail attachments from unknown sources.

Watch out for fraudulent emails regarding banking

Tuesday, February 28th, 2012

We’re still receiving complaints from users who fall victim to cyber criminals by blindly submitting their banking details via email. (see example below) Staff are once again warned under NO circumstances to do any activation of your bank details by clicking on a link in an email. Pay attention to the following: –  Your bank will never send you an email requesting personal and confidential information. – The address where the email is sent from is not an official bank email address. It might seem similar, but if you look closely you’ll notice small differences. – Take note of the address where the link diverts you to when you click on it. You will immediately notice it’s not a typical bank web address, but something completely unrelated. – You will also see that your name is never mentioned in the email. It’s a generic email sent to random people to harvest their information. If any irregularities occur on your account, your bank will call you. You also won’t receive an email from them if a large amount is deposited into your bank account. Remember, a cyber criminal knows what will grab your attention. If you have any doubts, rather contact your bank directly and make sure.
