Advarsel: Deling af giraf på Facebook er rent fup

Der er tale om en ganske omfattende viral kampagne på Facebook, der indbefatter en gåde indeholdende en giraf.

Men der er altså tale om ren scam eller fup, som er baseret på både pjat og noget der er taget ud af den blå luft, oplyser sikkerhedsfirmaet CSIS.

De naive Facebook-brugere er blevet lokket med følgende gåde:

- The Great Giraffe Game! The deal is I give you a riddle. You get it right you keep your profile pic. You get it wrong and you change your profile pic to a Giraffe for the next 3 days. I got it wrong, obviously! You have to MESSAGE ME ONLY SO YOU DON'T GIVE OUT THE ANSWER!

- Here is the riddle: 3:00 am, the doorbell rings and you wake up. Unexpected visitors, it's your parents and they are there for breakfast. You have strawberry jam, honey, wine, bread, and cheese. What is the first thing you open? Remember... Message only! If you get it right I'll post your name here, >>> if you get it wrong you change to a giraffe profile pic for the next 3 days.<<<

Og jo, svaret er "My eyes".

Men dem som ikke har løst opgaven korrekt, skal skifte deres profilbillede ud med billedet af en giraf. Hvilket rigtig mange har gjort.

Som en konsekvens kommer følgende advarsel, som spredes rundt blandt de personer, som er hoppet i med begge ben:

- A virus that exploits the recently discovered JPEG vulnerability has been discovered spreading over google's giraffe pictures. It's been done in the past, but with HTML code instead of the JPEG," said James Thompson, chief technical officer for SANS' Internet Storm Center, the organization's online-security research unit. "It is a virus, but it didn't spread very far. We've only had two reports of it."

- The Facebook message goes like this: "I just changed my profile picture to a giraffe, but my answer was wrong" When you do it, Facebook automatically gives the hackers your user mail and password, malicious code embedded in the JPEG image gives the hackers everything they need, James said.

- The code also installs a back door that can give hackers remote control over the infected computer. Antivirus expert Fred Hypponen of F-Secure warned on Wednesday that the JPEG exploit can also damage your Iphone if you charge it with your computer. By default, antivirus software only scans for .exe files. And even if users change the settings on antivirus software, the JPEG file name extensions can be manipulated to avoid detection. Microsoft and google are working on it now, oct 25. We recommend Facebook users: DO NOT change your profile picture to giraffes".

Ah nej. En viral kampagne med et hoax/kædebrev add-on?! Fedt! Ja, undskyld, men vi tillader os at smile over dette. Det er da for stupidt. Vi noterer os endvidere at der ikke findes en "Fred Hypponen" (men derimod en Mikko?) i F-Secure, og ej heller en "James Thompson" hos SANS. Tsk tsk, lyder det fra sikkerhedsfirmaet CSIS.

Og budskabet fra CSIS er klokkeklart:

- Lad være med at lade dig lokke af den slags virale kampagner.

Efterfølgende er der også dukket lignende fupnumre op med bland andet zebraer.
