North Korean Hack Breached 140,000 South Korean Systems (June 13, 2016)

North Korea-based hackers targeted the network management software used by approximately 160 companies and government agencies in South Korea and breached more than 140,000 computers. The attackers allegedly planted malicious software in the systems. The hack, which was intended to lay the ground for an overall massive cyberattack "has been thwarted," according to authorities in Seoul.

US Health and Human Services IG to Assess Medical Device Security Monitoring (June 9, 2016)

The US Department of Health and Human Services (HHS) Office of Inspector General's Fiscal Year 2016 Mid-Year Work Plan calls for an assessment of the Food and Drug Administration's (FDA's) review of cybersecurity control on wireless and Internet-connected medical devices. The HHS IG also plans to look into state Medicaid agency and contractor breach notification practices and responses.

NSA Could Use Internet-Connected Medical Devices for Surveillance (June 10 and 13, 2016)

NSA Deputy Director Richard Ledgett told an audience at the Defense One Tech Summit in Washington, DC, last week that the agency is examining ways to exploit the Internet of Things (IoT) to conduct covert monitoring. Ledgett said that the NSA is "looking at it sort of theoretically from a research point of view right now," and noted that conducting surveillance through medical devices could be "a tool in the toolbox."

FAA Panel Agrees on Airliner Cybersecurity Standards (June 12, 2016)

A panel of government and aviation-industry experts reached preliminary agreement on cybersecurity standards for airliners, including cockpit alerts in the event that critical safety systems are hacked. The concern addressed by the panel was described by the chair: "You have to worry about the direct attack, you have to worry about the indirect attack" from ancillary operations.

US House of Representatives Reject Amendment that Would Revive the Office of Technology Assessment (June 13, 2016)

US legislators voted down a measure that would have reestablished the Office of Technology Assessment. The advisory organization was originally created in 1972 to provide lawmakers with unbiased research and information to inform their legislative actions, but was dismantled in 1995 due to budget cuts.

South Korea Says North Korea Stole Fighter Jet Plans (June 13, 2016)

According to South Korean officials, attackers from North Korea stole thousands of defense industry documents, including designs for a US fighter jet. South Korea says that North Korea broke into more than 160,000 computers at 160 companies over a two-year period. The breaches were discovered in February.

Processor-Level Malware Detection (June 13, 2016)

Intel and Microsoft have worked together on the development of Control-flow Enforcement technology (CET), which would provide security at the chip level. CET aims to protect computers from attacks that exploit return-oriented programming and jump-oriented computing. These types of attacks "are particularly hard to detect or prevent because the attacker uses existing code running from executable memory in a creative way to change program behavior," according to an blog post by Baiju Patel, director of the platform security architecture and strategy team at Intel's Software and Services group. CET attempts to mitigate this problem with a shadow stack that stores control transfer operations.

Necurs Botnet Goes Mysteriously Silent (June 13, 2016)

The Necurs botnet, which for years has been used to distribute spam and malware, appears to have gone offline, but experts are unable to figure out exactly why. The level of malicious traffic emanating from the Necurs command-and-control network has diminished to nearly nothing.

Zbot Botnet Uses Fast Flux Technique (June 12, 2016)

RiskAnalytics has published a report on the Zbot botnet's use of "fast flux" to avoid detection. Fast flux uses the Domain Name System to hide. The technique has been known since at least 2007.

Mozilla Establishes Secure Open Source Fund (June 10, 2016)

Mozilla's newly-created Secure Open Source Fund will help pay for open source software security audits. The fund has initial funding of US $500,000 to be used to pay for professional audits to detect problems like the Shellshock and Heartbleed vulnerabilities in open source software. The fund, which is part of the Mozilla Open Source Support (MOSS) program, will also help implement fixes and manage flaw disclosure.

ICS Domain Name Squatting (June 10, 2016)

Many Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA) systems manufacturers have not taken steps to protect their brands from domain name squatters. Researchers found more than 400 instances of domains with names similar to a number of ICS/SCADA manufacturers. Some of those hosted malware or redirected visitors to other sites.
-http://www.computerworld.com/article/3082060/security/industrial-control-systems
-vendors-get-careless-on-domain-squatting.html

[Editor's Note (Williams): Whether you work in ICS or not, typo squatting can create risk. When you discover typo squatted domains targeting your organization, work with the registrar through your legal team to seize the domain on brand infringement grounds. Most malicious actors never answer and you may be able to control the domain in the equivalent of a default judgment. At a minimum, the registrar will sinkhole the domain and you've made the Internet a safer place for everyone. ]

Senator Proposes Single Cybersecurity IG for Federal Civilian Agencies (June 6, 2016)

In a speech at the Center for Strategic and International Studies (CSIS), Senator Sheldon Whitehouse (D-Rhode Island) said that there should be a single inspector general for cybersecurity for all federal civilian networks. Currently, each agency's inspector general is responsible for cybersecurity audits. Whitehouse said after the speech that he does not believe that such a shift would cause IGs to take their focus off cybersecurity. On the contrary, "They may pick up their game a little if they're worried that the roving inspector" will disclose their security problems. Former National Security Council cybersecurity adviser Ari Schwartz expressed concern that an overarching cybersecurity IG may lack the in-depth knowledge necessary to make the right decisions for each agency.
-https://fcw.com/articles/2016/06/06/whitehouse-ig-civilian-cyber.aspx
[Editor's Note (Northcutt): This could work. Whether you love FISMA or hate it, perhaps the greatest benefit it has is giving a grade. And that grade, given systematically, helps compare one agency to another. A single inspector general would give even more of the comparison. Their methods may not be perfect, but it adds to the preponderance of evidence as to the overall security posture of an agency. ]
