TOP OF THE NEWS

US Office of Personnel Management Acknowledges Second Breach (June 4, 2015)

The US Office of Personnel Management (OPM) has acknowledged that its network was breached late last year, compromising the personal information of four million current and former federal employees. The incident, detected in April, is the second breach of OMP systems in less than a year.
-http://www.washingtonpost.com/world/national-security/chinese-hackers-breach-fed

inese-hackers-suspected/

-http://arstechnica.com/security/2015/06/federal-agency-hit-by-chinese-hackers-ar
ound-4-million-employees-affected/

[Editor's Note (Pescatore): The focus on this breach should be how and why, but most of the attention is immediately jumping to who. How the attackers got in and why the vulnerability was there even after OPM had a serious breach less than a year ago needs to lead to lessons learned and fixing what must be systemic problems.
(Paller): The U.S. Department of Homeland Security's (DHS) failure to focus federal agencies on cyber hygiene, and measure and report progress on the effectiveness of defenses inplace, leads to the ease with which these attacks succeed. The U.S. Department of Defense (DoD) has seen the light and is now measuring cyber hygiene as a core readiness metric - - in both military and civilian elements. If DHS cannot match this capability, rapidly, it is reasonable for the next President to consider removing government-wide cybersecurity responsibility from DHS and concentrating it under the Department of Defense, as the Australians have done so effectively. (See the following story.) ]

Top Four Security Controls Have Prevented Attackers from Stealing Australian Government Data (June 2, 2015)

Australia's Signals Directorate director Steve Day told an audience at the Check Point Cyber Security Symposium in Sydney that cyber attackers have not stolen any sensitive information from the government over the last two years even when they have managed to breach networks. Day says the government's success in keeping data safe is due to agencies having adopted the Top 4 Security Controls.
-http://www.theregister.co.uk/2015/06/02/patchcrazy_aust_govt_fought_off_every_ha
cker_since_2013/

[Editor's Note (Pescatore): The Critical Security Controls "First Five" and the ASD Top 4 (done right) show up in over 80% of breach investigations as ways breaches could have been prevented. While doing these right is non-trivial, many enterprises and some government agencies are focusing on them as the foundation layer for increasing both the effectiveness *and* the efficiency of the entire security architecture and control set - and reaping those benefits. I used several real word examples (including the Australians) at my talk at the recent RSA Conference - see

NSA Surveillance Authority Broadened to Include Domestic Internet Traffic (June 4, 2015)

According to classified documents leaked by Edward Snowden, in 2012, the NSA was granted the authority to conduct surveillance on US Internet traffic without a warrant to investigate foreign cyber attacks. The documents indicate that the NSA pursued attackers even if there was no proof that the attacks originated outside the US. The expanded surveillance powers were the result of two secret Justice Department memos.

THE REST OF THE WEEK'S NEWS

Telstra CISO Says Attribution and Threat Hype Overshadow Defense Strategies (June 3, 2015)

Telstra CISO Mike Burgess, also speaking at the Check Point Cyber Security Symposium, said that "attribution distraction" and "threat distraction" take the focus away from what's important regarding breaches - the root cause of the incident. Rather than addressing the existing problems in an organization's defense strategy, Burgess noted that media coverage often appears to place greater emphasis on identifying the culprit or on overstating the nature of the threat. For the majority of major breaches, there is an identifiable root cause with a known solution.
-http://www.zdnet.com/article/telstra-ciso-blasts-cyber-attribution-distraction/
[Editor's Note (Pescatore): Reinforcing my comment on the OPM breach, above, there definitely is a lot of "Don't blame me/it was China and an APT" kind of hype and distraction going on. Much more fun for the press to write about, but boards of directors are much more interested in reducing the impact on the company's bottom line vs. threat attribution. (Murray): The media may trumpet it but the concern over attribution originates with law enforcement. They want to identify the perpetrator so that they can remove them.
(Ullrich): This story, and the story about companies not defending against old threats, are both indicators of an all too common tendency to chase the "latest greatest threat". Security professionals like life to be exciting and filled with new and fascinating exploits. On the other hand, security usually works best if it is boring. ]

China Blocking VPNs (June 3, 2015)

The Chinese government is taking steps to prevent its citizens from accessing Internet content it deems inappropriate by blocking virtual private networks (VPNs), which have come into greater use as the government has blocked more websites.
-http://www.theregister.co.uk/2015/06/03/china_cracks_down_on_censorship_vpn/
[Editor's Note (Murray): While China may have escalated it, the first shot in this trade war was fired by the US (Huawei). Retaliation should have been expected. We should not have embarked upon a trade war in one of the few markets where the balance of trade was in our favor. ]

Senate Passes USA Freedom Act (June 2, 2015)

The US Senate has passed the USA Freedom Act, which officially ends the NSA's wholesale collection of phone call metadata. Under the bill, which President Obama signed into law on Tuesday, June 2, telecommunications will store the data and the government can access them with orders from the Foreign Intelligence Surveillance Court.

FBI Wants Access to Social Media User Information (June 3 & 4, 2015)

The FBI wants congress to pass a law mandating that operators of social media sites and other web communication tools share customer information with law enforcement just as telecommunications companies do. Michael Steinbach, assistant director of the FBI's counterterrorism division, told the House Homeland Security Committee earlier this week that congress should develop Internet communication rules that are informed by the Communications Assistance for Law Enforcement Act (CALEA).

ies-should-help-us-prevent-encryption-above-all-else/

[Editor's Note (Honan): If passed this could have a major impact on the user base of US based social media sites outside of the US. Many non-users may not feel comfortable that their data will be subject to US law even if they are not located within the US. ]

Mozilla and Google to Make Scripting Safer (June 4, 2015)

Mozilla, Google, and Dropbox are developing a resource for browsers to help prevent man-in-the-middle attacks. The Subresource Integrity (SRI) check will allow browsers to check the integrity of scripts using hashes. SRI will be available in developer builds of Chrome and Firefox within a month.
-http://www.theregister.co.uk/2015/06/04/new_firefox_chrome_sri_script_whip_to_fo
il_maninthemiddle_diddle/

-http://www.w3.org/TR/SRI/
[Editor's Note (Ullrich): This is an interesting proposal. Right now, developers have two options when making use of popular javascript libraries like jQuery: (1) download the entire library and serve it from their own system, which offers more control about the integrity of the library, but takes a small amount of additional resources and may slow page load, or (2) keep them in their original location, trusting the developer to properly secure them. This proposal will allow web sites to add hashes to script tags to allow the browser to verify the integrity of the library.
(Murray): Welcome move. However, the browser remains the Achilles Heel of the desktop and the desktop that of the enterprise and the Internet. ]

Protect Systems Against Old Malware, Too (June 4, 2015)

Microsoft UK chief security advisor Stuart Aston told an audience at the RSA unplugged conference in London earlier this week that old malware can be just as harmful as the newly-discovered exploits that make headlines. Data indicates that 20 percent of Windows installations does not have current anti-virus protection.

GAO: Defense Agencies Need to Improve Insider Threat Monitoring (June 4, 2015)

According to a report from the US Government Accountability Office (GAO), the Defense Department needs to establish programs to help detect and prevent insider threats. The unclassified version of the report said that just half of the military "components" the report examined had established "a baseline of normal activity patterns" derived from observed system and user behavior.

Australian Company Paid Extortionists in Bitcoin (June 3, 2015)

A company based in Brisbane, Australia, paid online extortionists thousands of dollars in Bitcoins after the thieves stole data. When the company refused to pay an additional ransom, the attackers made threats against a child of a senior member of the company. The case has prompted Queensland police to warn businesses not to pay extortionists and to warn individuals about the dangers of posting personal information on social media.

Microsoft Fixes Flaw that Crashes Skype (June 3, 2015)

Microsoft has released an update to fix a flaw that crashes Skype when a specific eight-character string is received in an instant message. Users found that even when they tried to log on to Skype after the crash, Skype would download the most recent chat and it would crash again. The cycle would stop only when the user who sent the string deleted it. The issue affects Skype on Windows and Android platforms, with the exception of the touch version of Skype for Windows 8.1.
