Communication

IT takes to the airwavesIT op die lug

Friday, August 30th, 2013

The days when the Information Technology department was an unreachable, distant entity on the other side of Banghoek Road, are long gone. Since 2010 we’ve been pulling out all the stops and making an extra effort to ensure that there’s ample communication and interaction with all our clients and users on campus.

At the beginning of September (i.e. next week) we’re shaking winter’s dust from our shoes and entering yet another new era of communication. In future IT will no longer only reach you by e-mail, but also through MFM’s radio waves.

With an audience of 30 000 listeners between the ages of 14 and 28, there’s no doubt that IT will reach a much younger market, in particular students. This new means of communication provides us with the opportunity to speak to a larger portion of our users on campus and to get more involved with student issues.

So, from next week Tuesday at 11:45 there will be a bi-weekly special IT slot on MFM during the AM-PM-show. Since Bits & Bytes is steadily becoming an established brand, the slot will also be known as Bits & Bytes.

Bits & Bytes on air won’t merely be another institutional mouthpiece to promote IT, but rather an opportunity to discuss all kinds of technological developments. Students and staff will also be given the opportunity to ask questions via our Twitter feed and we’ll do our best to answer them on air.
 
We’re looking forward to our debut in radio coming Tuesday and hope you lend us your ears on 3 September at 11:45. Click here to listen to MFM live.
 

 

 

Die dae wat die Informasietegnologie-afdeling die onbereikbare entiteit aan die ander kant van Banghoekweg is, is lank reeds verby. Sedert 2010 het ons `n aktiewe poging begin aanwend om kommunikasie en interaksie met die res van kampus en almal aan wie ons `n diens lewer, te verbeter.

Begin September skud ons die winter se stof van ons voete en betree `n nuwe era van kommunikasie. Voortaan sal IT jou nie net bereik met e-pos nie, maar ook oor MFM se radiogolwe.

Met `n gehoor van 30 000 luisteraars tussen die ouderdom van 14-28 ouderdomsgroep, is daar geen twyfel dat IT `n jonger mark, en spesifiek studente sal bereik nie. Dié nuwe kommunikasiekanaal gee aan ons die geleentheid om `n groter deel van ons gebruikers op kampus te bereik en meer betrokke te raak by studentekwessies.

Daar sal dus voortaan twee-weekliks `n spesiale IT-insetsel op MFM wees op Dinsdae, 11:45 gedurende die AM-PM-show. Aangesien Bits & Bytes reeds `n gevestigde handelsmerk begin word, sal die insetsel ook bekendstaan as Bits & Bytes.
 
Bits & Bytes op die lug sal nie bloot nog `n institusionele mondstuk wees nie, maar eerder `n geleentheid om interessante tegnologiese verwikkelinge te bespreek. Daar sal ook geleentheid aan studente en personeel gegee word om d.m.v. ons Twitter-voer vrae te vra wat ons op die lug sal beantwoord. 
 
Ons sien uit daarna  om komende Dinsdag ons toetrede tot radio te maak en hoop jy skakel Dinsdag om 11:45 by ons in. Kliek hier om na MFM te luister.

What does Rumplestiltskin and spam have in common?Wat het Repelsteeltjie en gemorspos in gemeen?

Friday, August 16th, 2013

Once of the most common questions we get asked by users is “How do these spammers get my e-mail address?” 

There are a number or methods that these spammers use, but today we will focus on one of the methods,  The “Rumplestiltskin” attack.

A dictionary or Rumplestiltskin attack is an attack where the spammer floods e-mail servers with usernames selected from a dictionary. The name of course, comes from the old Grimm’s fairytale.

Long, long ago when the university’s e-mail system was still very primitive and e-mail addresses were limited to 8 characters, most personnel at the university had simple names like ab@sun.ac.zaaa1@sun.ac.za, bv@sun.ac.za. It is relatively easy to make up a list of common letter combinations and just add @sun.ac.za onto it to create a e-mail list. Add to that common  role-based accounts, such as admin, help and support, as well as adding the latest Baby Names list and you have a list that can be used to launch a Rumplestiltskin attack.

If you send  E-mail to Unknown Users or address that do not exist, Why bother?

Firstly rather than spammers buying a list from other spammers, they can just spam to any possible name they can generate. It might seem rather inefficient but sending email is cheap.

The second reason – which is far more sinister – is that spammers use these techniques to generate lists of valid email accounts. They first send to a generated list and when they do get a response or the receiving mail server doesn’t answer back and say“unknown e-mail address”, this allows them to either sell these lists of “verified” emails or be more accurate in their other spamming activities.

With this second reason in mind, you should be able to see the danger of replying to these mails or filling in the “opt-out” option, that is commonly included in such mails, or by setting your “Send delivery receipt” to automatic on your e-mail. As soon as these spammers realize that there is a real person at the other end of the e-mail, they will increase their spam. They get paid to send out the mail, not for how many people respond to them.

In our next edition we will focus on a second way spammers harvest e-mail addresses in – Part 2 – Trojan Horses, Bots and Zombies

[ARTICLE BY DAVID WILES]

Een van die algemeenste vrae wat gebruikers vir ons vra is: Hoe kry hierdie gemorsposversenders my adres?! 

Daar is `n hele paar metodes, maar die keer fokus ons op die “Repelsteeltjie”-aanval.  

`n Woordeboek of Repelsteeltjie-aanval is `n aanval waar die gemorspos-versender e-pos bedieners oorval met gebruikersname uit `n woordeboek. Die naam is natuurlik afkomstig van die ou Grimm sprokiesverhaal.

Lank, lank gelede toe die universiteit se e-pos sisteeem nog primitief was en e-posadresse beperk tot 8 karakters, het die meeste personeel eenvoudige adresse gehad soos ab@sun.ac.zaaa1@sun.ac.za, bv@sun.ac.za.  

Dis redelik eenvoudig om `n lys van algemene letterkombinasies saam te stel en @sun.ac.za by te las en `n e-pos adreslys saam te stel. Voeg daarby algemene rolgebaseerde rekeninge soos admin, help en support, sowel as die nuuste babaname lys en jy het `n lys waarmee jy jou aanval kan loods. 

Hoekom sal jy `n e-pos stuur na onbekende gebruikers of `n adres wat nie bestaan nie?

Eerder as om `n lys te koop by ander gemorsposverspreiders, is dit makliker en natuurlik goedkoper om net gemorspos te stuur na enige moontlike naam wat gegenereer kan word. 

Die tweede rede – en `n meer oneerlike een – is dat versenders dit gebruik om juis `n lys van geldige adresse op te bou. Eers word `n gegenereerde lys gestuur en wanneer hulle `n antwoord kry of die e-pos bediener aan die ontvangkant nie terugantwoord en bevestig dat die adres ongeldig is nie, kry hulle die geleentheid om die lys te verkoop as “bevestigde” adresse of om meer akkuraat te wees met hul aktiwiteite.

Hiermee in gedagte, kan jy jouself indink hoe gevaarlik dit is om op hierdie e-posse te antwoord of te kliek op die “teken uit” opsie wat algemeen by die tipe e-posse ingesluit word. Selfs om “Send delivery receipt” op outomaties te stel hou `n gevaar in.

Sodra die skuldiges besef dat daar `n regte, lewendige persoon aan die ander kant van die e-pos is, sal die gemorspos net eenvoudig toeneem. Hulle word betaal om die e-posse suksesvol uit te stuur, nie noodwendig vir hoeveel mense daarop reageer nie.  

Volgende keer kyk ons na nog `n metode wat gebruik word om adresse te oes in Deel 2 – Trojaanse perde, Robotte en Zombies

eduroam: internet without fusseduroam: internet sonder moeite

Friday, August 2nd, 2013

If you’re a regular visitor to universities, particularly in Europe, you’re most likely aware of eduroam and how it simplifies travelling for academic purposes. We’re happy to announce that eduroam will henceforth also be available at Stellenbosch University.

But what for those of us who don’t know – what is eduroam exactly? eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community. It started as a project of the  Trans-European Research and Education Networking Association (TERENA) in Europe and has gained momentum throughout the research and education community.

eduroam is now available in 54 countries, including South Africa and provides an easy way to get internet access without any fuss. It allows students, researchers and staff from participating institutions to obtain internet connectivity across campus and when visiting other participating institutions by simply opening their device.

Users can move between campuses and visit other participating institutions at home or abroad and get instant, secure network access, without having to arrange and use guest accounts or extra passwords. The visiting user is authenticated using the same credentials (username and password)  they use at their home institution, the institution or organisation they are affiliated with.

To activate eduroam for your department, please e-mail help@sun.ac.za with your details and  see www.eduroam.org for more information. More information on eduroam in South Africa can be found at http://eduroam.ac.za/

As jy `n gereelde besoeker is aan universiteite, veral in Europa, is jy waarskynlik alreeds bewus van eduroam en hoe dit jou lewe as reisende akademikus vergemaklik. Daarom is ons opgewonde om aan te kondig dat eduroam ook voortaan by Universiteit Stellenbosch beskikbaar sal wees.

Maar vir die van ons wat nie weet nie – wat is eduroam presies? eduroam (education roaming) is  veilige, wêreldwye swerwende (“roaming”) toegangsdiens. Die diens het ontstaan as `n projek deur die  Trans-Europese Navorsing en Opvoedkunde Netwerk Organisasie  in Europa en het mettertyd spoed opgetel onder die navorsings en opvoedkunde-gemeenskap. 

eduroam is tans beskikbaar in 54 lande, insluitend South Africa en die diens verskaf `n maklike manier om toegang tot die internet te kry sonder te veel moeite. Dit gee aan studente, navorsers en personeel van deelnemende instellings die geleentheid om `n internetverbinding regoor kampusse en by ander akademiese instellings te kry deur net hul toestel (hetsy dit `n skootrekenaar, tablet of selfoon is) aan te sit.  

Gebruikers kan tussen kampusse beweeg en ander deelnemende instellings tuis of oorsee besoek en onmiddellik veilige netwerktoegang kry, sonder om ekstra gasterekeninge of wagwoorde te installeer. Die besoekende gebruiker se identiteit word gestaaf deur middel van dieselfde inligting (gebruiksnaam en wagwoord) wat gebruik word by sy eie akademiese instelling. 

Om eduroam vir jou departement te aktiveer, e-pos help@sun.ac.za met jou volledige inligting en vir meer inligting besoek www.eduroam.org. Meer informasie oor eduroam in Suid-Afrika, kan gevind word by http://eduroam.ac.za/

Beware of suspect phone callsOppas vir suspisieuse oproepe

Tuesday, July 9th, 2013

If you receive a call at home from someone who claims to be a Microsoft representative, the odds that it’s a variation of the Indian phone scam is most likely.

These fraudsters target phone numbers everywhere to try and con computer users into installing malware and spyware on their pc’s by claiming they’re ridding the said pc of all kinds of viruses and threats.

The caller claims that the security settings on their pc has to be updated and after this is done, they ask your credit card number for payment of their service.

Do not fall for these scam artists. Ask yourself how they know know you have a pc? Did they address you on your name and have your details (contact numbers, etc)? Did they specifically state their company’s name? The odds that someone will call you out of the blue to assist you with computer updates are in all probability less than zero.

More info on this scam:

As jy `n oproep ontvang vanaf `n beweerde Microsoft-verteenwoordiger is die kans goed dat dit `n weergawe van die Indiese telefoon “scam” is. Kuberkriminele teiken foonnommers wêreldwyd en probeer rekenaargebruikers bedrieg deur verstellings te maak wat deur virusse en ander gevare van die betrokke rekenaar sal verwyder. 

Die persoon beweer dat die sekuriteitsverstellings van die rekenaar verouderd is en opgedateer moet word. In die proses gee die slagoffer toegang tot sy rekenaar en kan “malware” en “spyware” geinstalleer word. Die kredietkaartnommer word ook versoek as betaling vir die diens wat gelewer is. 

Moet onder geen omstandighede val vir hierdie skelmstreek nie. Vra jouself die volgende vrae af – hoe weet hulle jy het `n rekenaar? Het hulle jou aangespreek op jou naam en jou inligting verskaf? Het hulle duidelik die naam en inligting oor die maatskappy waarvoor hulle werk verskaf? Die waarskynlikheid dat iemand jou uit die bloute sal skakel om te help met jou rekenaars se opdaterings is bitter skraal.
