Attackers Install DDoS Bots On Amazon Cloud

Posted by timothy on from the fully-buzzword-compliant dept.

itwbennett (1594911) writes "Attackers are exploiting a vulnerability in distributed search engine software Elasticsearch to install DDoS malware on Amazon and possibly other cloud servers. Last week security researchers from Kaspersky Lab found new variants of Mayday, a Trojan program for Linux that's used to launch distributed denial-of-service (DDoS) attacks. The malware supports several DDoS techniques, including DNS amplification. One of the new Mayday variants was found running on compromised Amazon EC2 server instances, but this is not the only platform being misused, said Kaspersky Lab researcher Kurt Baumgartner Friday in a blog post."

      If you choose a cloud offering which does that for you then yes, you don't have to worry about things like software updates and patching.

      However, if you choose a cloud offering which is essentially a hosted server, then you still have to worry about all the things you would with your own local server, excluding power and hardware faults.

      Amazon AWS is a platform provider, its not a fully managed solution and never has been - people have been caught out by that before when availability zones failed and suddenly people realised the benefit of having redundant instances in multiple availability zones.

  6. Stupid sensationalism by Imagix · · Score: 4, Insightful

    So why is Amazon being specifically mentioned here? What makes this specific to Amazon? Is Google Compute Engine somehow immune to this? Or Azure, or any other hosting provider? Or self-hosted? Better headline: "Servers compromised through known vulnerability, admins failed to update software to close vulnerability."

    1. Re:Stupid sensationalism by Anonymous Coward · · Score: 2, Interesting

      My guess is they just looked at a couple EC2 machines, and since no one uses Azure or Google Compute Engine, they just didn't bother following up on those and made a blanket statement that it applies to all environments (which it does). This has nothing to do with EC2, or Azure or any other environment, really. This is a vulnerability in a piece of 3rd party distributed search engine software that a bunch of people were too lazy to update.

      The real headline just doesn't perform quite as well as the clickbait they came up with.

  8. I choose not to cloud by Anonymous Coward · · Score: 1

    I am not paranoid in the least, but I know from experience that if you provide a reason for hackers to attack. No matter if that's a platform for sending out malware or DOS or whatever. Or if its just to mine personal information and exploit credit cards, identification and whatever else. The hackers will no doubt be trying to circumvent
    security and you know they will succeed. I don't see cloud as any more viable then saying it will never rain again and always be Sunny. We know that will never happen. The cloud means trusting total strangers with your information as if they can. That would be like walking up to a total stranger and handing them your wallet.
    Yea, maybe you will find one in a few who will honestly devote their time and effort into protecting it. Then you will have some who will throw it away blaming you for even giving them the wallet to begin with. Then you have the rest who will say "sucker" time to better myself and see what I can do with this information.
    At least with handing your wallet to a person you still have that chance of detecting some sort of trust with that person. With the cloud, you do not have a personal
    experience to back up that trust.

  9. It is not so much about the cloud - it is low qual by Anonymous Coward · · Score: 0

    People tend to forget lessons, learned even recently. Amazon probably does not care what type of software its customers are running. There are tons of low quality software out there, like that OpenSSL code with its Heartbleed expoit, which nobody noticed for years. Who knows how many system were compromised due to this before the exploit was even discovered and reported? It was also reported that a couple of community developers, working part time, did that piece of software code, which just did cost a couple of billions for IT industry to fix. Assumption that being open source software, that code is verified by thousands of eyeballs, proved wrong. Net, net, this Amazon cloud expoit shows that Amazon cloud is a nice scalable vehicle for cheap DDOS hosting of parasitic malware within badly written code hiding somewhere among thousands of exploitable software systems. One can assume, that this is only the beginning of Amazon and other IAAS cloud vendors problems, taken into account how many low quality disorganized community code is loaded on Amazon servers today.

  10. Oh now the Cloud is falling by Anonymous Coward · · Score: 1

    This would be wittier if it was Microsoft SkyDrive, but meh.

    The cloud is failing. This is one specific instance of how virtualization's "lower costs" aren't lower at all. Somewhere along the line, the person responsible for this outsourcing to AWS, misunderstands that they are still responsible for security and maintenance, and in fact should be hiring MORE staff, not laying staff off to fake cost savings to shareholders. It will take only one really high profile AWS "destruction" and then no enterprise business will ever bother with cloud services again. Then we can go back to owning/leasing equipment cheaply instead of paying AWS to hold our data hostage.
