Twitter Hacked by 'Iranian Cyber Army'



Microblogging site Twitter has been hacked by a group of protesters calling themselves the Iranian Cyber Army. The attack forced Twitter offline for more than an hour overnight, leaving Twitter users unable to log on to the service or send tweets.

Visitors to Twitter.com were automatically redirected to another web page, which displayed a green flag and English and Arabic writing.


"This site has been hacked by the Iranian Cyber Army," read the message. "The USA thinks they control and manage internet access, but they don't. We control and manage the internet with our power, so do not try to the incite Iranian people."

Twitter said that a DNS attack – where a web address is diverted to another site – was to blame for the outage.

"Twitter's DNS records were temporarily compromised tonight but have now been fixed," wrote Biz Stone, Twitter's co-founder, in a blog post. "As some noticed, Twitter.com was redirected for a while but API and platform applications were working. We will update with more information and details once we've investigated more fully."

Twitter was widely used by Iranian citizens protesting against what they believed to be an unfair election result earlier this year. The microblogging service even delayed a period of planned maintenance so that the site could stay online, giving protesters the ability to communicate with those outside Iran.

It is unlikely that any computers were infected or compromised after being redirected to the hacker's website, said Graham Cluley, a security expert with Sophos. He said that there was "no indication" that the page Twitter users were redirected to carried malicious code that could have infected computers.

"This attack appears to have had political motivations rather than been designed to steal confidential information from users," he wrote on his blog. "Of course, just because a message saying 'This site has been hacked by Iranian Cyber Army' has been posted on a webpage does not necessarily mean that hackers from Iran are responsible for the defacement.

"However, Twitter was widely used earlier this year by those wishing to share information about anti-government protests [in Iran], and rumours spread in July that planned maintenance on the site was delayed to allow Iranians to continue to share information from inside the country as citizen journalists commented on the controversial election result."

Twitter said that normal service had been restored.

Kerajaan Jeumpa, Kerajaan Islam Pertama Nusantara

Teori tentang kerajaan Islam pertama di Nusantara sampai saat ini masih banyak diperdebatkan oleh para peneliti, baik cendekiawan Muslim maupun non Muslim. Umumnya perbedaan pendapat tentang teori ini didasarkan pada teori awal mula masuknya Islam ke Nusantara. Mengenai teori Islamisasi di Nusantara, para ahli sejarah terbagi menjadi 3 kelompok besar, yaitu pendukung (i) Teori Gujarat (ii) Teori Parsia dan (iii) Teori Mekah (Arab). Bukan maksud tulisan ini untuk membahas teori-teori tersebut secara mendetil, namun dari penelitian yang penulis lakukan, maka dapat disimpulkan bahwa Teori Mekkah (Arab) lebih mendekati kebenaran dengan fakta-fakta yang dikemukakan. Teori Mekkah (Arab) hakikatnya adalah koreksi terhadap teori Gujarat dan bantahan terhadap teori Persia. Di antara para ahli yang menganut teori ini adalah T.W. Arnold, Crawfurd, Keijzer, Niemann, De Holander, SMN. Al-Attas, A. Hasymi, dan Hamka. i Arnold menyatakan para pedagang Arab menyebarkan Islam ketika mereka mendo...

MyWare: Personalized Service or Invasion of Privacy?

There's a fine line between what is considered a knowledge database and an invasion of privacy, and that line is likely to be determined by marketing. This week we wrote an article about Please Rob Me - a service that identifies Foursquare and Gowalla check-ins on Twitter and lets others know that a person is not home. While location-based services are often touted for their social and recommendation-based benefits, the realization that they can be used negatively have many questioning the responsibility of those groups that collect the data. In mid January Facebook founder Mark Zuckerberg stated that the age of privacy had come to an end and we responded that evolving preferences were not a valid justification of the elimination of privacy preferences . Nevertheless, between cookie tracking and browser identifiers like those shown in the EFF's Panopticlick and the fact that it only takes your zip code, gender and birthdate to identify you, it's hard to ensure to...

Johnny Depp Meninggal Hanya Hoax

Aktor Johnny Depp jadi trending topic di situs jejaring sosial, Twitter. Penyebabnya karena Depp disebut-sebut telah meninggal dunia. Benarkah? Ternyata tidak. Bahan perbincangan para pengguna Twitter didasarkan dari screenshot situs berita CNN yang disebutkan dimuat tahun 2004 silam. Screenshot berita itu pun sebenarnya telah dinyatakan sebagai kesalahan teknis oleh CNN. CNN ketika itu mengaku telah lalai dalam memuat nama korban kecelakaan lalu lintas menjadi Johnny Depp. Padahal yang menjadi korban saat itu bukan aktor top Johnny Depp. Sejumlah situs berita asing yang selama ini dikenal memiliki keakuratan dan kecepatan berita pun tidak memuat mengenai meninggalnya Depp. Situs BBC, Reuters, Contact Music, Female First, Daily Mail, The Sun hingga CNN tidak melansir berita meninggalnya pemain film 'Donnie Brasco' tersebut pada Minggu (24/1/2010).
