ICS-CERT Reports Rise in Attacks Against Energy Sector (July 1, 2013)

In the Spring 2013 ICS-CERT Monitor newsletter, the US Department of Homeland Security's (DHS's) Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) warns of a spike in brute force attacks against process control networks at natural gas companies. The companies targeted were mostly in the Midwest and Great Plains states; the attacks occurred between February 22 and March 8. Between October 1, 2012 and May 2013, ICS-CERT responded to more than 200 incidents involving critical infrastructure systems. Fifty-three percent of those were against energy companies.



[Editor's Note (Assante): It is easy to lose sight of the ICS picture over time, but the number of directed attempts to identify and intrude into ICS has been steadily increasing. The effort has been organized; the incidents link together as larger campaigns with specific themes (in this case natural gas entities). The ICS-CERT has stepped up their game and has 'broken the mold' by working with the national security community to responsibly provide actionable information about threats. The challenge is now upon system owners and operators to equip themselves to act on this information and best shape their defenses. Every fly away team assist should establish new targets in both cybersecurity competency and practice for the effected entity!
(Henry): ICS-CERT is one of the programs at DHS that works well, and their partnership with the FBI creates a great synergy. The awareness ICS-CERT brings to the sector is critical, and the intelligence they're able to share is absolutely a step in the right direction for public-private partnership.
(Weatherford): While there is undoubtedly more malicious activity focusing on the oil and natural gas sector (and all those using ICS), part of this spike can be attributed to more awareness of the ICS-CERT and that they are being utilized as a private sector resource more than ever. The ICS-CERT Team has done an excellent job of outreach to critical infrastructures and accomplishes a lot with a surprisingly small number of people. They are one of the organizations in the government that works well and with the right funding, they could be vastly more valuable to the Nation.

US Cyber Challenge and Virginia Tech Hosted Cybersecurity Camp and Competition (July 1, 2013)

Virginia Tech and the US Cyber Challenge (USCC) hosted the US Cyber Challenge Eastern Regional Summer Camp in Roanoke, Virginia during the last week of June. More than 50 people selected in part because of their strong performance in Cyber Quests, an online competition help by USCC in April. The camp included four days of instruction, a career fair, and an Executive Roundtable. It concluded with a team capture-the-flag cyber competition. Members of the winning team received US $1,000 scholarships.

[Editor's Note (Weatherford): The Nation needs more of these events and competitions and more private sector companies should be coming to the table with funding and resources. The value returned in qualified people vastly outstrips whatever small investment they make. ]

Symbiotic Malware (July 1, 2013)

Researchers have discovered two pieces of malware that help each other maintain a foothold on the computers they have infected. The two different strains of malware, known as Vobfus and Beebone, download updated versions of each other. The newest versions are often unknown by malware detection programs. Vobfus spreads through malicious links on websites, over network links, or on USB drives, and is normally the first of the two to infect machines. Once installed, Vobfus downloads Beebone, which recruits the infected machine to become part of a botnet.

Attack on South Korean Presidential Web Site Exposes User Data (July 1, 2013)

A recent attack on the website of the South Korean presidential office compromised the personal information of 100,000 people. The exposed data include birth dates, identification numbers, and IP addresses. Users' passwords and registration numbers, which are comparable to US Social Security numbers (SSNs), were encrypted.

Nasty Malware Targets South Korean Government and Media Networks (June 28, 2013)

The recent cyberattacks against South Korean government and media networks have been found to involve malware that wipes data from hard drives and makes computers unusable. The malware, called Korhigh, permanently deletes data and overwrites hard drives' master boot records and bears similarities to malware used in attacks on South Korean websites earlier this year.



Atlassian Fixes Vulnerability in Crowd Single Sign-On Tool (July 1, 2013)

Atlassian has fixed a critical security issue in its Crowd single sign-on and identity management tool that could have been exploited by hackers to gain access to login credentials and sensitive data. Crowd is used by 1,000 organizations, including government agencies, banks, software companies, and telecommunication companies, in 55 countries.


US Senators Want "Public Answers" About Scope of NSA Surveillance (June 28 & July 1, 2013)

US legislators are calling for "public answers" regarding the scope of the National Security Agency's (NSA's) surveillance of people in the US. In their letter to Director of National Intelligence James R. Clapper, the group of 26 senators asks if the NSA collected personal information, such as credit card purchases, library records, and firearms sales, in addition to phone records. The senators also ask if the collected data include cell-site location data.


Text of Letter:

[Editor's Note (Honan): The allegations about NSA surveillance could have far reaching consequences. Following revelations alleging the US spied on EU diplomats and embassies there are concerns that US and EU trade talks may be in jeopardy.

Security Flaws in Phone App Library (June 30 & July 1, 2013)

Vulnerabilities in the GNU ZRTPCPP open-source security library used by some secure mobile phone apps could be exploited to allow arbitrary code execution and crash applications. The flaws include a remote heap overflow, several stack overflows, and information leakage.


Alleged Shadowcrew Member Extradited From Paraguay (July 1, 2013)

Aleksi Kolarov, who has been held in Paraguay since 2011, has been extradited to the US to face charges related to the Shadowcrew carding forum. In 2004, the US charged Kolarov with conspiracy, transferring false identification documents, and offering access devices without authorization.



[Editor's Note (Henry): Two key points in this piece say a lot about where law enforcement is headed in cybersecurity. First, coordination and collaboration with foreign partners is absolutely critical to successfully track and prosecute adversaries. Secondly, government agencies and prosecutors are taking these crimes seriously; continuing to "hunt" for the adversary for more than seven years demonstrates a commitment to mitigate these threats, and sends a signal to those who believe they are outside the long arm of the law. ]

US Administrative Office of the Courts' 2012 Wiretap Report (June 28, 2013)

The US Administrative Office of the Courts 2012 Wiretap Report notes that 15 wiretaps last year encountered encrypted communications. In previous years, there have been a total of seven other instances. In four of the cases, officials were not able to decrypt the messages. This is the first time that officials have reported being thwarted by encryption "since the AO began collecting encryption data in 2001." According to the report, there were 3,395 authorized wiretaps from state or federal judges in 2012. The numbers do not include "interceptions regulated by the Foreign Intelligence Surveillance Act of 1978."
[Editor's Note (Pescatore): Encryption foiling .1% of wiretaps shows that strong encryption is hard to do. Which, of course, is also why the penetration of persistent encryption of data is so low - it is hard to do right. Harder than it should be, but many of the same barriers that have resulted in reusable passwords continuing to dominate need to be overcome in order for persistent encryption to break out. ]

Former Vice Chairman of Joint Chiefs of Staff is Suspect in Stuxnet Leak (June 27 & 28, 2013)

Retired US Marine General James Cartwright is being investigated as the possible source of the Stuxnet leak. In June 2012, The New York Times published a detailed story about Stuxnet, but sources were not identified. General Cartwright has also been credited as the person who presented the idea of Stuxnet to the George W. Bush administration. General Cartwright served as vice chairman of the Joint Chiefs of Staff from 2007-2011.



[Editor's Note (Pescatore): Two great cartoon captions recently in New Yorker magazine about leaking, in both cases a manager is handing a document across big desk to underling: (1) "Leak this against my wishes." and (2) "Leak to the press that my Administration won't stand for any more leaks." ]
