Incidents of the Cryptowall 3.0 ransomware are increasing on campus.
• DO NOT open .ZIP attachments. (recent incidents reported had a .ZIP attachment with the subject “my resume”)
• Stay away from unknown, suspicious or unofficial websites and torrents offering game, movie or software downloads and DO NOT click on any pop-ups.
This ransomware infects your PC when you visit lesser known websites and particularly if you download games, movies and software or click on attachments in your e-mail, for example zip files.
The ransomware copies all the data on your hard drive, encrypts and deletes it and you’re left with gibberish. A ransom fee is demanded, but the odds that you’ll get your data back at all, are slim.
Cryptowall not only infects your own hard drive data, if also targets all drives you are connected to, including your shared departmental drive. You will lose the data on your hard drive and data on the network drive might be able to be recovered up to a certain point, but unfortunately this can’t be guaranteed.

Insidente van die Cryptowall 3.0 virus neem tans toe op kampus.
• MOENIE .ZIP aanhangsels oopmaak nie.
• Bly weg van onbekende, suspisieuse webwerwe en torrents wat speletjies, flieks of sagteware aanbied nie en MOENIE op enige pop-ups kliek nie.
Hierdie ransomware kan op verskeie maniere op jou rekenaar beland – as jy speletjies, flieks of sagteware aflaai van nie-amptelike webwerwe OF kliek op aanhegsels, byvoorbeeld .zip leêrs in `n e-pos.
Cryptowall 3.0 kopieer alle data op jou hardeskyf, enkripteer dit en laat slegs onherkenbare en onbruikbare simbole. `n Losprys word geëis as jy jou data wil terughê, maar die kans vir herwinning is skraal.
Cryptowall besmet nie net jou hardeskyf se data nie, maar alle skywe waaraan jy op daardie oomblik verbind is, insluitende jou departementele netwerkspasie en jou kollegas se data. Data op die hardeskyf is verlore en data op netwerkskywe kan tot op `n punt herstel word, maar daar is geen waarborg nie.
