Verizon signals Yahoo data breach may affect acqusition

Verizon has signaled that Yahoo's massive data breach may be enough reason to halt its US$4.8 billion deal to buy the internet company.On Thursday, Verizon's general counsel Craig Silliman said the company has a "reasonable basis" to believe that the breach involving 500 million Yahoo accounts has had a material impact on the acquisition. This could give the company room to back out or get a large discount."We're looking to Yahoo to demonstrate to us the full impact," he added. "If they believe that it's not, then they'll need to show us that."In response, Yahoo said, "We are confident in Yahoo’s value and we continue to work towards integration with Verizon."To read this article in full or to leave a comment, please click here

Worth Reading: Data Centric Computing

Unlike enterprise business applications of the 1990s, systems processing this growing deluge of unstructured data have to deal with an entirely different class of problems. As data scales beyond petabytes, simply ingesting, storing, retrieving, and processing data becomes challenging using traditional server and application architectures. currentThe sheer scale of infrastructure needed to support these workflows is, for most companies, daunting. There is network complexity required to support terabytes per hour data ingest rates, a large and growing storage tier, and a compute infrastructure that continuously scans incoming data to classify and process it. —The Next Platform

Microsoft is changing how you use the Control Panel in Windows

We all know Windows 10 is a continuously evolving operating system with regular changes made over the course of its release cycle. It seems those changes are extending to the Control Panel, the central hub for system settings. Windows10Update.com noted that a modest but significant change in build 14942, the latest Fast ring preview version released by Microsoft, made a change to how the Control Panel is presented when using the Power Menu (the Windows and X key) Instead of the Control Panel shortcut that was placed between the Task Manager and File Explorer in the operating system, there is now a full menu of options that match the Control Panel's set of applets. To read this article in full or to leave a comment, please click here

iOS 10’s one-month adoption rate hits 68%

iOS 10 adoption continued to climb a month after its release, with some sources pegging the upgrade on more than two-thirds of iPhones.At the one-month mark, iOS 10 accounted for 68.2% of all iOS editions detected by Mixpanel, whose analytics platform is used by mobile app developers to track usage and user engagement.That was slightly higher than the 62.8% accumulated by iOS 9 last year at the same post-release point, and far above iOS 8's 48.9% in September 2014.The modern record for iOS uptake remained with iOS 7 -- a major UI (user interface) and UX (user experience) overhaul -- which captured a 72.7% share in its first month.To read this article in full or to leave a comment, please click here

Thousands of online shops compromised for credit card theft

Almost 6,000 online shops have been compromised by hackers who added specially crafted code that intercepts and steals payment card details.These online skimming attacks were first discovered by Dutch researcher Willem de Groot a year ago. At that time, he found 3,501 stores containing the malicious JavaScript code. However, instead of getting better, the situation is increasingly worse.By March the number of infected shops grew by almost 30 percent to 4,476, and by September, it reached 5,925. More than 750 online stores who were unwillingly skimming payment card details for attackers in 2015 are still doing so today, showing that this type of activity can go undetected for months, the researcher said in a blog post.To read this article in full or to leave a comment, please click here

Real-time domain name lookups

Reverse DNS requests request the domain name associated with an IP address, for example providing the name google-public-dns-a.google.com for IP address 8.8.8.8.  This article demonstrates how the sFlow-RT engine incorporates domain name lookups in real-time flow analytics.

First, use the dns.servers System Property is used to specify one or more DNS servers to handle the reverse lookup requests. For example, the following command uses Docker to run sFlow-RT with DNS lookups directed to server 10.0.0.1:
docker run -e "RTPROP=-Ddns.servers=10.0.0.1" \
-p 8008:8008 -p 6343:6343/udp -d sflow/sflow-rt
The following Python script dnspair.py uses the sFlow-RT REST API to define a flow and log the resulting flow records:
#!/usr/bin/env python
import requests
import json

flow = {'keys':'dns:ipsource,dns:ipdestination',
 'value':'bytes','activeTimeout':10,'log':True}
requests.put('http://localhost:8008/flow/dnspair/json',data=json.dumps(flow))
flowurl = 'http://localhost:8008/flows/json?name=dnspair&maxFlows=10&timeout=60'
flowID = -1
while 1 == 1:
  r = requests.get(flowurl + "&flowID=" + str(flowID))
  if r.status_code != 200: break
  flows = r.json()
  if len(flows) == 0: continue

  flowID = flows[0]["flowID"]
  flows.reverse()
  for f in flows:
    print json.dumps(f,indent=1)
Running the script generates the following output:
$ ./dnspair.py
{
 "value": 233370.92322668363, 
 "end": 1476234478177, 
 "name": "dnspair",

Azure roundup: FPGAs, new VMs and fresh Europe regions

Microsoft's big Ignite conference for IT pros wrapped up at the end of September, and that means the company dumped a ton of new cloud capabilities to attract people to Azure. Here's the run-down on all the major news you need to know about:Azure data centers in Germany and the UK go live In its continuing quest to expand the global reach of its public cloud platform, Microsoft announced the general availability of four new Azure regions: two in the U.K. and two in Germany. The UK data centers are fairly standard cloud regions, but data in the German DCs is under the control of T-Systems International, a German company that's a subsidiary of tech giant Deutsche Telekom.To read this article in full or to leave a comment, please click here

What is MANRS and does your network have it?

While the internet itself was first envisioned as a way of enabling robust, fault-tolerant communication, the global routing infrastructure that underlies it is relatively fragile. A simple error like the misconfiguration of routing information in one of the 7,000 to 10,000 networks central to global routing can lead to a widespread outage, and deliberate actions, like preventing traffic with spoofed source IP addresses, can lead to distributed denial of service (DDoS) attacks.The Internet Society (ISOC), a cause-driven nonprofit organization that seeks to promote the open development, evolution and use of the Internet and the parent organization of the Internet Engineering Task Force (IETF) standards body, is moving to change that. In 2014, ISOC introduced its Mutually Agreed Norms for Routing Security (MANRS) initiative. Today ISOC announced that the initiative membership has more than quadrupled in its first two years, growing from its initial nine network operators to 42 network operators today.To read this article in full or to leave a comment, please click here
