Hackers who targeted Samsung Pay may be looking to track individuals

The security breach at Samsung subsidiary LoopPay was probably more about spying than about gathering consumer data for profit, and the worst could be yet to come, a security analyst said Wednesday. Samsung acknowledged the attack on LoopPay, which it acquired in February for technology that it uses in its Samsung Pay service. It said hackers only breached LoopPay's office network, not systems used by Samsung Pay. The affected servers have been isolated and no personal payment information was put at risk, according to Samsung.To read this article in full or to leave a comment, please click here

They’re baaaack! Verizon’s zombie cookies to track users across massive AOL ad network

Remember Verizon’s zombie cookies, hidden super-cookie identifiers that tracked users across the Internet? They’re baaaack! moviemaniacsDE Poltergeist screenshot Verizon was previously caught manipulating users’ traffic by inserting supercookies. “By attaching a Unique Identifier Header to all traffic that passes through their network, Verizon could effectively build profiles about users habits, the sites they visit, and deliver targeted advertisements based on this tracking,” explained EVDO. “This Unique Identifier Header was then popularly renamed the ‘Zombie Cookie’ since even after being deleted, the tracking cookie would be added back to the network and users would be tracked again.”To read this article in full or to leave a comment, please click here

Former NSA chief undercuts FBI’s desire for encryption backdoors

The former head of the NSA says the U.S. is better served by strong encryption than it would be by encryption schemes with backdoors that allow law enforcement to decrypt the content of communications, according to reports, and he should know.Under Michael Hayden’s watch as director of the NSA, the agency exploited back doors into phone switches in Greece in order to spy on calls including those made by the Greek prime minister and the mayor of Athens.The legal-intercept capabilities baked into the switches are supposed to be used only under strict legal supervision, but they can be abused. According to a story by James Bamford for The Intercept, documents stolen by Edward Snowden help show that the NSA took unauthorized advantage of legal-intercept backdoors in the Greek phone system to eavesdrop on what calling parties assumed would be private communications.To read this article in full or to leave a comment, please click here

Non-technical manager’s guide to protecting energy ICS/SCADA

Sophisticated cyber-attacks known as Advanced Persistent Threats (APT) are a growing challenge to the energy sector of our nation’s critical infrastructure. These attacks can largely be attributed to well-funded, dedicated nation-state actors.APT attacks against Industrial Control Systems (ICS) and to Supervisory Control and Data Acquisition (SCADA) systems are increasing; the U.S. Department of Homeland Security (DHS) Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) cited ICS/SCADA and control system networks as one of the top two targets for hackers and viruses. These vulnerabilities begin with the human interface (13% of vulnerabilities required local access) and end with the actual Internet-facing ICS/SCADA hardware (87% of vulnerabilities are web-accessible).To read this article in full or to leave a comment, please click here

Attackers target OWA for domain credentials

A targeted attack against Outlook Web Application (OWA) illustrates how far adversaries will go to establish persistent control over the organization's entire network.As seen in recent breaches, attackers typically use stolen credentials or malware to get a foothold on the network, and then target the domain controller. Once attackers successfully compromise the domain controller, they can impersonate any user and move freely throughout the enterprise network. Since the OWA server, which provides companies with a Web interface for accessing Outlook and Microsoft Exchange, depends on the domain controller for authentication, whoever gains access to the OWA server automatically wins the domain credentials prize.To read this article in full or to leave a comment, please click here

IoT will become a matter of life or death for security pros

Orlando, Fla. -- Internet of Things means different things to different people; self-driving cars, smart cities, connected homes, health and fitness apps, etc. But for security professionals, IoT will become a safety issue. Christian Byrnes That’s the stark assessment of analyst Christian Byrnes, who delivered Gartner’s scenario for cyber-security looking out toward the year 2020.Gartner is all-in on IoT, predicting that we’re moving inexorably toward “the universal connectivity of everything,’’ according to Byrnes. The impact cannot be overestimated.To read this article in full or to leave a comment, please click here(Insider Story)

Worth Reading: Revisiting Internet Governance

The realpoltik is that in addition to all of its other aspects — such as its social and economic elements — the internet has become a weapon in the arsenal of the military and security forces. Of course, we all knew that this was the case but the abovementioned affairs brought this out into the open, and I think even the most militant opponents of internet governance were shocked by the extent to which these agencies were already using the internet and the other technologies it facilitates, such as data-gathering and data analytics. -via circleid

Control Plane Protection in Cisco IOS

How does Internet work - We know what is networking

CoPP – Control Plane Protection or better Control Plain Policing is the only option to make some sort of flood protection or QoS for traffic going to control plane. In the router normal operation the most important traffic is control plain traffic. Control plane traffic is traffic originated on router itself by protocol services running on it and destined to other router device on the network. In order to run properly, routers need to speak with each other. They speak with each other by rules defined in protocols and protocols are run in shape of router services. Examples for this
