Alleged NSA data dump contain hacking tools rarely seen

A stolen cache of files that may belong to the National Security Agency contains genuine hacking tools that not only work, but show a level of sophistication rarely seen, according to security researchers.That includes malware that can infect a device’s firmware and persist, even if the operating system is reinstalled.  “It's terrifying because it demonstrates a serious level of expertise and technical ability,” said Brendan Dolan-Gavitt, an assistant professor at New York University’s school of engineering.He’s been among the researchers going over the sample files from the cache, after an anonymous group called the Shadow Brokers posted them online.To read this article in full or to leave a comment, please click here

Real-time web analytics

The diagram shows a typical scale out web service with a load balancer distributing requests among a pool of web servers. The sFlow HTTP Structures standard is supported by commercial load balancers, including F5 and A10, and open source load balancers and web servers, including HAProxy, NGINX, Apache, and Tomcat.
The simplest way to try out the examples in this article is to download sFlow-RT and install the Host sFlow agent and Apache mod-sflow instrumentation on a Linux web server.

The following sFlow-RT metrics report request rates based on the standard sFlow HTTP counters:
  • http_method_option
  • http_method_get
  • http_method_head
  • http_method_post
  • http_method_put
  • http_method_delete
  • http_method_trace
  • http_method_connect
  • http_method_other
  • http_status_1xx
  • http_status_2xx
  • http_status_3xx
  • http_status_4xx
  • http_status_5xx
  • http_status_other
  • http_requests
In addition, mod-sflow exports the following standard thread pool metrics:
  • workers_active
  • workers_idle
  • workers_max
  • workers_utilization
  • req_delayed
  • req_dropped
Cluster performance metrics describes how sFlow-RT's REST API is used to compute summary statistics for a pool of servers. For example, the following query calculates the cluster wide total request rates:
http://localhost:8008/metric/ALL/sum:http_method_get,sum:http_method_post/json
More interesting is that the sFlow telemetry stream also includes randomly sampled HTTP request records with the following attributes:
  • protocol
  • serveraddress
  • serveraddress6
  • serverport
  • clientaddress
  • clientaddress6
  • clientport
  • proxyprotocol
  • proxyserveraddress
  • proxyserveraddress6
  • proxyserverport
  • proxyclientaddress
  • proxyclientaddress6
  • proxyclientport
  • httpmethod
  • httpprotocol
  • httphost
  • httpuseragent
  • httpxff
  • httpauthuser
  • httpmimetype
  • httpurl
  • httpreferer
  • httpstatus

Cisco to shed 5,500 staff in refocus on IoT, security, and cloud

Cisco Systems plans to lay off about 7 percent of its global workforce in a restructuring that will see it further focus on hot IT areas such as the internet of things, security, collaboration, next-generation data centers, and the cloud.The move will cost the company around $700 million in redundancy payments to the roughly 5,500 staff who will be out of jobs in the coming months. The layoffs will hit some of Cisco's smaller and more mature business areas where long-term growth prospects are low, the company said."We expect to reinvest substantially all of the cost savings from these actions back into these businesses and will continue to aggressively invest to focus on our areas of future growth," Cisco said in a statement.To read this article in full or to leave a comment, please click here

Cisco, Fortinet issue patches against NSA malware

Customers of certain Cisco and Fortinet security gear need to  patch exploits made public this week after a purported hack of NSA malware.Both companies have issued fixes to address exploits that were posted online and after they found the exploits represent real threats to some of their products, including versions of Cisco’s popular PIX and ASA firewalls and versions of Fortinet’s signature Fortigate firewalls.Other exploits may affect Watchguard and TOPSEC products, but those companies did not immediately respond to inquiries. When they do this story will be updated.To read this article in full or to leave a comment, please click here
