“The first thing I did was call up a couple of my friends, who had been on the front lines of DDoS attacks and they said they had seen this,” says Matt Dolan, who’s been the executive director of the DDoS mitigation and response team at Drupal, one of the major online game developers.
“They said, ‘Oh my God, this is a DSO, this DSO is behind it.’
I said, no, this isn’t.
It’s a bunch of DSOs doing it.”
Dolan says it was the first time anyone had noticed the exploit, which he calls a “master bot” that took advantage of the vulnerability in the Drupal web application.
Dolan is not a bot developer himself, but he says it’s “a really nice way to get around a lot of the limitations of the Drupal application” that could allow someone to do anything.
“The way it works is if somebody is connecting to your server, if they can connect to your backend, then you can do anything that they can do,” he says.
“If you can redirect their data or make it look like it’s coming from another IP address or something like that, they can also use the backend to do all sorts of stuff.”
DDoS is a technique that allows a malicious website to overwhelm an entire network.
It was invented in 2001, and has been used by cybercriminals for years.
It involves sending large amounts of traffic, usually via the internet, to a target server, which then blocks it.
“So, basically, a malicious person can send a bunch more traffic to your website, and you can respond to that traffic with a response from your backend,” Dolan explains.
“It’s really a way to make it very hard for the attacker to do a lot.”
DSO exploits can be deployed against many sites, but Dolan’s team found that they could be used to target a single Drupal site.
DSTO is an exploit that’s commonly used by hackers, but it’s also a feature in Drupal that allows the site to respond to the attack by redirecting the traffic to another server.
The exploit is called a “Master Bot” and is designed to make the attack appear to come from the server hosting the site, when in fact it’s being launched from a different one.
The Drupal team first discovered DSTOs in March, when the code was used to attack a DSTo-enabled website.
“We’re still working to figure out exactly what we’ve done, but this is how it works,” says Dolan.
The DST OUs were “quite simple,” says Drupal developer Matt Cavanagh, who has worked on the site since 2010.
They are a way for the server to respond when a certain request comes in.
The server sends a request to the DST, and the DSO sends back a response.
“That response is a response that’s not really a response,” says Cavanag.
“This is really a really nice piece of software.
You can use it to send a message to your frontend, which is what we’re doing with this master bot.”
DSTs also use different tricks to try and trick the server into doing things.
“I can send the master bot a message, and then it just jumps to the next DST,” says David Jones, a security researcher at the security firm Cloudflare who has been working on a new vulnerability in Drupal.
“And it’s like, what?
Are you sure it’s going to work?
And if it’s not, it jumps back to the master server.”
“So basically, what we want to do is say, ‘If you don’t want us to do that, we’re going to do it ourselves,'” Jones says.
It takes a little while for the Dsto to figure this out, but eventually it “runs out of memory,” and the master can start to “run out of CPU,” he adds.
“DSTOs are very fast, and when they’re in memory they’re really fast,” Cavanagan says.
Dstos are “very, very powerful.”
Dstoing an attack with DSToes requires the user to have access to the server’s server, where the DStos will send back a reply.
The code to launch the DSSO is relatively straightforward, Dolan adds.
“You have to create the Dsta, then it will send you a message back, and that message is the Dscpsto,” he explains.
In theory, this should work, because Drupal can handle DSCPs “without any issues.”
