Tor Network Used To Command Skynet Botnet
angry tapir writes "Security researchers have identified a botnet controlled by its creators over the Tor anonymity network. It's likely that other botnet operators will adopt this approach, according to the team from vulnerability assessment and penetration testing firm Rapid7. The botnet is called Skynet and can be used to launch DDoS (distributed denial-of-service) attacks, generate Bitcoins — a type of virtual currency — using the processing power of graphics cards installed in infected computers, download and execute arbitrary files or steal login credentials for websites, including online banking ones. However, what really makes this botnet stand out is that its command and control (C&C) servers are only accessible from within the Tor anonymity network using the Tor Hidden Service protocol."
That's the cost of sane privacy controls -- sometimes it can be used for bad purposes. Society should be looking inwards at the cause of this. Spying on people, tracking their every movement, and abusing the legal systems of countries created a need (and a demand) for a type of security system that would protect you to the n-th degree. Now we've got a solution and it will be abused. What needs to happen is companies that make software need to invest into security and response. We're never going to stop the threat, but we can minimize the damage and downtime.
A perfect opportunity to continue their campaign on the evils of anonymity and tools that enable it.
Why is this such a surprise? If anyone wants to hide a server/service behind the cloak of anonymity, then yes, a tor hidden service is the way to do it. People do it for good reasons (eg. journalists under threat of death for publishing accounts of gov't actions) and nefarious reasons (silk road comes to mind). Hell, even Yelp blocks access from tor nodes b/c (they say) a large majority of bot traffic comes from the tor network. Is this really the first time a botnet has used tor, or is this the first time a botnet has been caught?
Next thing you know, they'll say the bad guys and terrorists use VPN to access the internet.
sysadmins and parents of newborns get the same amount of sleep.
DoS attack against the ToR hidden service; from inside the ToR network.
This is just the bot net people being lazy and taking the easy approach. It's already been shown you can design decentralized networks that require no "bootstrap" information like DNS in order to find other nodes and communicate. But it is beyond the abilities of these low-level social miscreants to create, so they're piggybacking on a network that they think can hide their malicious activity. Tor only anonymizes the source of the data; Anything between the exit node and destination is sent in the clear and likely they've made some mistake that'll allow it to be blockable.
Of course, this is exactly what the oppressive governments of the world (and those who oppress by claiming they're "liberating" others), have been looking for to shut down the Tor network. You can expect more attempts at legislating it away to come soon. Fundamentally though it doesn't solve the problem, which is that the criminal underworld has figured out how to do what industrialists figured out 50 years ago: If you take just a little from a lot of people, you can get very rich, and those people won't fight back because the cost of retaliation is higher than the loss. As a result, people everywhere are being nickel and dimed to death.
Botnets are simply the illegal mirror counterpart to the legal crime of draining pensions and unethical banking to turn a profit: Harm many only a little, and you too can be rich.

Citizen encryption has so tremendous potential that we can't allow goverments and criminals to be the only ones using it. We really need to start pushing encryption into the masses.
But... the future refused to change.
From the little I've read, it seems that they use a distributed host of volunteer servers to run the TOR network, so it might not be that easy to 'shut-down' the entire network (lack of centralized host) - If I'm wrong, I'd love to know why.
My concern is that they will make TOR access illegal. Clearly, we can't count on Google/Microsoft/Amazon/Apple/Facebook/Big-Biz to raise a finger - they prey off identifying and targeting customers. Privacy and anonymity must hurt their bottom line. So unlike SOPA/PIPA, I doubt that any major group will oppose a new law against this. And most people won't care - hell, if Wikipedia didn't have a blackout, I doubt SOPA would have got any news time on a 'major' news network at all.
Is there a way to detect TOR access uniquely? Or does the encryption make it look like any VPN/secure connection? I recollect reading about a method that could identify IP address accessing TOR (don't remember the details), I'm not sure if that hole was plugged (or if it can be plugged).
The old tautology, "if you outlaws firearms, only outlaws will have firearms" applies to Tor. (In fact, I'd go as far as to argue that many cryptographic mechanisms are covered by the second amendment, especially if you consider cryptography's military purpose, and that some ciphers have been regulated by the DOD as munitions. They cover the same role in protecting your property, identity and reputation from aggression, and as the "well regulated militia" clause demands, pseudonymous discussions are necessary tools to help people discuss political matters.)
The simple truth is you can shut down all the law-abiding people with Tor nodes, and the botnet creators will just run Tor nodes on their network. It would be absolutely trivial for botnet owners to get together and set up huge Tor networks and put access up for pay on the black market.
Tor's bandwidth and latency are sufficiently abysmal that it acts as a throttle. Overwhelming a number of servers via the Tor network would probably be not much easier than overwhelming the entire Tor network.
