黑客攻击工具威胁Healthcare.gov的网站
destroy Obamacare
Researchers have uncovered software available on the Internet designed to overload the struggling Healthcare.gov website with more traffic than it can handle.
"ObamaCare is an affront to the Constitutional rights of the people," a screenshot from the tool, which was acquired by researchers at Arbor Networks, declares. "We HAVE the right to CIVIL disobedience!"
In a blog post published Thursday, Arbor researcher Marc Eisenbarth said there's no evidence Healthcare.gov has been subjected to any significant denial-of-service attacks since going live last month. He also said the limited request rate, the lack of significant distribution, and other features of the tool's underlying code made it unlikely that it could play a significant role in taking down the site. The tool is designed to put a strain on the site by repeatedly alternating requests to the http://www.healthcare.gov and http:www.healthcare.gov/contact-us addresses. If enough requests are made over a short period of time, it can overload some of the "layer 7" applications that the site relies on to make timely responses.
The screenshot below shows some of the inner workings of the unnamed tool.

Re: 黑客攻击工具威胁Healthcare.gov的网站
感谢分享这个新闻。Healthcare.gov上线以来问题不断，现在又出现针对它的攻击工具，虽然目前看起来威胁不大，但这类工具的公开传播本身就是一个警示。网络安全在任何公共服务平台上都值得高度重视，尤其是涉及用户隐私和医疗数据的网站。Re: 黑客攻击工具威胁Healthcare.gov的网站
根据Arbor Networks研究人员的调查，这一针对Healthcare.gov的黑客工具已在互联网上被发现，但其实际威胁性有限。目前没有证据显示该网站遭受过重大攻击，且该工具在请求速率、分布范围及代码设计上存在局限，难以产生实质性破坏。专家指出，该工具主要通过反复请求特定页面来增加服务器负载，但短期内难以瘫痪网站。Re: 黑客攻击工具威胁Healthcare.gov的网站
这篇报道提到的攻击工具虽然在技术上存在缺陷，但背后的政治化表达值得警惕。将政府网站作为抗议目标，不仅可能影响普通用户的正常访问，更可能触犯法律。网络安全研究机构确认尚未发生实质性大规模攻击是好事，不过这种“破坏性工具”的公开传播本身就意味着潜在风险。希望相关部门能加强防护，也提醒网民理性表达诉求，不要采取违法手段。
