Craigslist experienced an unexpected cyber attack Sunday night, preventing users from accessing the online service by redirecting them to other websites like Digital Gangster, The New York Times, and even YouTube.

Jim Buckmaster, the chief executive officer of Craigslist, made a blog post around 8 pm on Sunday, explaining the situation. According to him, the site's domain name service, or DNS, was compromised, leading to people being redirected to different websites.

"The issue has been corrected at the source but many internet service providers (ISPs) cached the false DNS information for several hours," he said. This meant that some users are still unable to access the site for the time being.

The attack could be considered a protest, as the users who get redirected to YouTube found themselves watching an animated video entitled "Introducing Neals" with rap lyrics that that mentioned neutrality, privacy online and freedom, according to Gizmodo.

There was also a chance that the Craigslist hacking was done to point out flaws in Craigslist's security system and not intended to cause harm. The hacker implemented DNS hacking, which compromises a website's domain, but does not seek to penetrate their security measures and merely bypass it.

A hacker and musician by the name of YTCracker is being blamed for the Craigslist cyber attack.

Allegations of YTCracker's involvement stems from when he once hacked the Goddard Flight Center page on NASA's website. He posted warnings on the page telling the government to update and improve their security. The NASA hacking coincidentally happened 15 years before the Craigslist hacking, down to the date.

There was also the fact that the "Introducing Neals" video was YTCracker's own production and that he also owns the Digital Gangster website.

YTCracker gave a statement to Slash Gear denying his involvement in the matter

"Really though, I have no idea. It's some member of my site being a dingus," he said, before adding that he was still most likely going to be blamed for it.
