Tumblr hacked?
- rohit6223 14y agoNo Surprise. It gets down many times. Only great thing about it is that its free..
- rootinier 14y agoYep. http://www.businessinsider.com/tumblr-hacked-2012-12 http://www.businessinsider.com/tumblr-hacked-2012-12 tl;dr: if you have a Tumblr account (and an active session), delete your cookies before opening any *.tumblr.com site.
- shortformblog 14y agoKeeping an eye on this. The post in question looks like this: https://dl.dropbox.com/u/58607934/Screen%20Shot%202012-12-03%20at%2010.31.27%20AM.png https://dl.dropbox.com/u/58607934/Screen%20Shot%202012-12-03... It has nailed a number of major accounts, including The Verge, USA Today, Reuters and The Daily Dot. Buzzfeed has tips on how to keep safe: http://www.buzzfeed.com/ryanhatesthis/hacker-group-exploits-security-hole-in-tumblr http://www.buzzfeed.com/ryanhatesthis/hacker-group-exploits-... Update: The GNAA says that the hack was part of an anti-blogging campaign. > This was just another part of our "anti-blogging" campaign. GNAA's stance on blogging in general has always been a negative one: in short, blogging is lowering journalistic standards to the point where the number of friends a murderer has on Facebook has become news. http://www.guardian.co.uk/technology/2012/dec/03/tumblr-cyber-worm-anti-blogging http://www.guardian.co.uk/technology/2012/dec/03/tumblr-cybe...
- nbashaw 14y agoAt the bottom of the spam post it says if you delete the post it will delete your Tumblr account. Since this spreads by people viewing it, it's probably important to point out that deleting the posts will not delete your tumblr account, and you should do it immediately so people viewing your blog don't get infected themselves.
- j2labs 14y agoNothing particularly interesting seems to have actually happened. Some posts got onto the Dashboard, which was still running. In fact, everything was still working just fine. Script kiddies found a small crack and went for it.
- shortformblog 14y agoMy entire dashboard was filled with these worm posts an hour ago, and hit a number of major sites.
- lysol 14y agoIt's not really a script kiddie if it's an original exploit, and is still a vulnerability that has cost businesses money.
- j2labs 14y agoWhat is your source for that info? Also, whether or not it cost the business money has nothing to do with the quality of the break-in.
- freehunter 14y agoWho cares about the quality or the skill it took? If it's an unskilled attack, it's even worse. If script kiddies can break into your site, your security is alarmingly poor. The things that matter during an attack: how much damage was caused, what kind of data was compromised, and how much it will cost to get things fixed. The quality of the attack is only a factor when it comes to cost/benefit of fixing the vulnerability.
- j2labs 14y agoMy first comment actually addresses each of your points.
- elcapo 14y ago"Script-kiddies" don't author exploits, or discover vulnerabilities.
- schill 14y agoLooks like a Base64-encoded JS URI in the video player URL. Somewhat sneaky. How it ends up redirecting the page to a reblog URL isn't clear. https://gist.github.com/4196142 https://gist.github.com/4196142
- derpenxyne 14y agoThe exploit uses a "data-uri script tag" in the video embed field. In other words, it runs some sort of script through the section of the site that's supposed to only allow video embed codes from sites like YouTube and Vimeo. A pretty serious security hole.
- matthuggins 14y agoMind sharing where you found this info? Did you figure it out yourself?
- schill 14y agoSee point #10 from http://www.buzzfeed.com/ryanhatesthis/hacker-group-exploits-security-hole-in-tumblr http://www.buzzfeed.com/ryanhatesthis/hacker-group-exploits-...
- biot 14y agoIf you suspect a site has been compromised, wouldn't a better approach be to submit this as a text article explaining your reasons rather than linking to the affected site? Depending on the nature of the hack, the title could easily have been: Was Tumblr hacked in order to do drive-by malware installs? (tumblr.com) Now everyone who clicks is potentially at risk.
- 47eo 14y agoIndeed, it was kind of stupid from the submitter.
- sstiernborg 14y agoAgreed! TNW Article: http://thenextweb.com/insider/2012/12/03/a-worm-is-hijacking-tumblr-blogs-and-posting-spam-said-to-affect-thousands-of-accounts/ http://thenextweb.com/insider/2012/12/03/a-worm-is-hijacking...
- g-garron 14y agoThanks God I click on it while on Linux :)
- thezilch 14y agoHacking vector was fixed: https://twitter.com/tumblr https://twitter.com/tumblr Tumblr engineers have resolved the issue of the viral post attack that affected a few thousand Tumblr blogs. Thanks for your patience.
