We’ve been having plenty of stormy weather over the past few days, so in keeping with the theme, did you know you even get e-mail storms?

“An email storm is a sudden spike of Reply All messages on an email distribution list, usually caused by a controversial or misdirected message. Such storms start when multiple members of the distribution list reply to the entire list at the same time in response to the instigating message. Other members soon respond, usually adding vitriol to the discussion, asking to be removed from the list, or pleading for the cessation of messages. If enough members reply to these unwanted messages this triggers a chain reaction of email messages. The sheer load of traffic generated by these storms can render the email servers inoperative, similar to a DDoS attack.

A related phenomenon occurs when a subscriber to a mailing list emails the mailing list to “UNSUBSCRIBE”. People will reply to the hapless individual on the mailing list, half of them advising on how to unsubscribe, the other half referring to the manual of the mailing list manager. More subscribers will reply to the previous round of respondents, again to the list, this time about mailing list etiquette.

Some email viruses also have the capacity to create email storms, by sending copies of themselves to an infected user’s contacts, including distribution lists, infecting the contacts in turn.”

Die Wes-Kaap is die afgelope week met mening deur stormweer geteister. Maar het jy geweet dat daar selfs in die tegnologiese wêreld storms is – e-pos storms.

`n E-pos storm is `n skielike toename in Reply All boodskappe op `n e-pos verspreidingslys, gewoonlik veroorsaak deur `n kontroversiële of verkeerdelik geadresseerde boodskap. Hierdie storms ontstaan wanneer veelvuldige lede van `n verspreidingslys antwoord aan almal op die hele lys in reaksie op die aanhitsende boodskap. Ander lede antwoord gevolglik vinnig, vra om verwyder te word van die lys of dat die boodskappe moet stop, maar gooi daardeur nog meer olie op die vuur. 

Indien genoeg lede antwoord op hierdie ongevraagde boodskap ontlont dit `n kettingreaksie van e-posadresse. Die brute lading van verkeer gegenereer deur dié storms kan selfs e-pos bedieners plattrek.

`n Soortgelyke verskynsel vind plaas wanneer `n intekenaar van `n verspreidingslys aan die lys e-pos stuur op te  “UNSUBSCRIBE”. Ander lede sal die arme individu antwoord en raadgee oor hoe om die lys te verlaat of die persoon verwys na die handleiding. Nog meer intekenare sal op die vorige persone antwoord – hierdie keer oor e-pos etiket.

Sommige e-pos virusse kan ook e-pos storms veroorsaak deur kopieë van hulself te stuur na `n besmette gebruiker se kontakte en verspreidingslyte en dan ook die kontakte in die proses besmet.

If you receive an email claiming to be from the IT department (see example below), do not open it or click on any of the links.

This is a phishing email attempting to acquire your passwords and other information. Immediately delete the email and do not reply to it.

IT e-mails will always be in the same format with IT’s name, correct contact details, the SU logo and and English and Afrikaans version. Please read our guidelines on how to distinguish between an offical e-mail and a phishing e-mail here.

Indien jy `n e-pos ontvang met onderstaande inhoud wat lyk of dit deur die IT-afdeling gestuur is, moet onder geen omstandighede op die skakels kliek nie.

Hierdie is `n “phishing” e-pos wat poog om u wagwoord en ander inligting te oes. Verwyder dadelik die e-pos en moenie daarop reageer nie.

IT e-posse sal dieselfde formaat hê met IT se naam, regte kontakdetails, die US-logo en `n Afrikaanse en Engelse weergawe. Lees ook asseblief ons riglyne oor hoe om te onderskei tussen `n amptelike e-pos en `n “phishing” e-pos hier.

If your first mail in the morning is junk mail or spam, it’s enough to start your day off on the wrong foot. But did you know you can do something about it?  

Spam, or junk mail is defined as identical, disruptive e-emails sent to a large amount of e-mail or cellphone users.  When a receiver clicks on one of the links in the message, he/she is diverted to a phishing website or websites containing malware.  Spam e-mails can also contain hidden malware scripts.

Recently there has been various iterations of spam and phishing. One variation seems to be from SARS, another from ABSA and yet another one from the IT department.  Don’t ever respond ever to mail sent to you by “persons unknown”. If you are unsure phone or e-mail the IT Helpdesk (021-8084367) or e-mail them at helpinfo@sun.ac.za, otherwise call or e-mail your local computer expert who can advise or at least check-up for you.

Mail from Information Technology will always be branded and clearly addressed to you, will have an English and an Afrikaans translation and will always contain links that point to the “sun.ac.za” domain and never anything else.  

Unsure how to distinguish between the real thing and spam or phishing e-mails? Read more about it on our selfhelp wiki and you’ll find various examples on our blog.

If you’re bombarded by spam om a regular basis, there’s one way of declaring war on it. Did you know you can send the relevant mail to IT so we can block the user, domain and/or service provider? Just follow these simple instructions below.

HOW TO REPORT A SPAM E-MAIL 

As jou eerste e-pos een of ander vorm van gemorspos aanneem, is dit genoeg rede om jou frustrasievlakke voor jou eerste koppie koffie al die hoogte in te laat skiet. Maar kan jy iets daaraan doen?

Gemorspos, of te wel “spam”, is wanneer identiese, meestal steurende,  boodskappe na `n groot hoeveelheid e-pos- of selfoongebruikers gestuur word. As `n ontvanger kliek op een van die skakels in die boodskap, word hulle herlei na strikroof webwerwe of webwerwe wat “malware” huisves. “Spam” e-posse kan ook versteekte “malware” skripte bevat.

Die afgelope tyd was daar verskeie weergawes van gemorspos en “phishing. Voorbeelde van SARS,  ABSA en selfs `n e-pos wat voorgee om van IT te wees, het opgeduik. Hoe oortuigend dit ookal lyk, moet nooit reageer op `n e-pos wat aan jou gestuur word deur `n onbekende entiteit nie. Indien jy enigsins twyfel, skakel (021-8084367) die IT Dienstoonbank of stuur vir hulle e-pos by helpinfo@sun.ac.za. Kontak andersins jou plaaslike rekenaardeskundige wat ten minste vir jou kan raad gee of die e-pos kan nagaan.  

`n E-pos van IT sal altyd duidelik herkenbaar wees en spesifiek aan jou gerig. Daar sal altyd `n Afrikaanse en Engelse weergawe wees en die skakels sal altyd wys na Mail from  “sun.ac.za” domein en niks anders nie.

Steeds onseker hoe om te onderskei tussen die regte ding en gemorspos of “phishing” e-posse? Lees meer daaroor op ons selfhelp wiki en jy kan ook verskeie voorbeelde op ons blog kry.

As jy op `n gereelde basis toegegooi word onder gemorspos, is daar `n manier waarop jy kan terugbaklei. Het jy geweet jy kan die betrokke e-pos aan IT stuur sodat ons die gebruiker, sy domein en/of diensverskaffer kan blok? Volg net die eenvoudige instruksies hier onder.
