A Bored Hacker Easily Stole And Defaced More Than 70 Subreddits (vice.com)

An anonymous reader writes: Hacker, BVM, said he's "lost count" of the number of subreddits he's stolen and defaced, but estimates that the number is more than 70. Subreddits like r/pics, r/starwars, and r/gameofthrones, and many others, have been defaced just in the last few days. He claims Reddit's crummy security, and lack of two-factor authentication are what has made his exploits possible. "Reddit's security is shit," he says. "If Reddit would simply add 2FA it would be a lot harder to get in." Why is BVM hacking these subreddits? "No reason really. Just boredom. It's not like it's really a challenge or anything so I just do it to pass time," the hacker told Motherboard in an online chat. BVM didn't comment on how exactly he is taking over subreddits. However, he did admit he's been hacking into moderators' accounts and then changing the CSS style of the pages, replacing it with a note taking responsibility. Reddit appears to be responding to these incidents quickly, restoring the subreddits.

    If true, I'm guessing it's credential reuse, phishing, or possibly XSS/CSRF. The volume hints at XSS/CSRF, but the suggestion to implement 2FA says otherwise since it may not mitigate such vulnerabilities.

      Assuming this is in fact their fault. If the hacker is taking an out-of-band approach such as reusing passwords from other leaks, there isn't really a discrete vulnerability in Reddit's codebase. The fact that such passwords could be used to access accounts could be described as a weakness in Reddit's security, but the actual vulnerability exploited lies in whatever system was originally compromised. Same thing with phishing--it's not really Reddit's fault if users can be tricked into disclosing credentials via channels outside of their control.

      That Reddit's response has been to restore hacked subreddits seems to indicate it's something of this nature. Otherwise, they'd (hopefully) patch the issue immediately and publish an advisory.

An attack like this would be trivial to pull off: aggregate all recent leaks, scrape moderator usernames from Reddit, filter the leaked creds using the scraped usernames, and go to town.

      Which is plain juvenile. The correct (and more effective) strategy is to take your eyeballs elsewhere. Engaging a site that you disagree with actually helps the site.

      Social media is essentially porn. The people who use it the most aren't out to engage other people, they're looking for a quick and easy hit of stimulation; the only difference is that it's outrage, not horniness that gets titillated. Do I have to spell this out? You act out your outrage and get paid in attention; some of that attention reacts with outrage and in turn gets attention, including from you. So you react, and the cycle goes on, the outrage market makers milk homeopathic quantities of revenue from each act of outrage. And integrated over the sheer volume out there, those fractions of penny per flame post add up to real money.

      It literally doesn't matter what you believe, as long as you believe it as obnoxiously as possible. You are, to social media companies, nothing but an outrage milk-cow.

      Porn is actually better for you than social media, and better for society as a whole because horniness is a less harmful drive to titillate than outrage.

    It's really kind of pointless. I had no life at the time and nothing better to do than spend hours/days trying to infiltrate various websites. I was often successful. Once you get in you get a bit of an ego boost, poke through some data you weren't supposed to be seeing, then that's pretty much it. Most of the content was private/personal, and boring to me.

There are many more people than just the right wing that don't like it when things aren't slanted their way, of all sorts of political backgrounds. Remember little miss "what difference does it make" and I don't know much about servers but I'll run my own anyways? I don't have much of a definitive list, just picking up things as I go along, and from what I've been told the generation currently in grade school are getting the understanding that if they don't like how they are treated by staff, (a substitute teacher, for example) they can go to the office and complain. I've had bad teachers and substitutes, but I had some understanding that being able to deal with the situation prepared me for things in the future. Many of the parents of such children don't like the lessons that are different, not slanted their way, but the lessons they rail against are not the ones that are making the kids have a low tolerance. If someone hasn't already bought them like me, Goodwill stores and thrift shops should have materials that state they are for teaching common core. If that fails, I don't find it unlikely to source the materials from some other place inexpensive, relatively speaking.
