DHS Secretary Pushes Critical Infrastructure Cyber Reorganization Plan (June 30 and July 1, 2016)

US Department of Homeland Security (DHS) Secretary Jeh Johnson told the Senate Judiciary Committee that he has "asked Congress to authorize the establishment of a new operational Component within DHS, the Cyber and Infrastructure Protection Agency." The new agency would replace the National Protection and Programs Directorate.

[Editor Comments ]
(Paller): This is DHS's most important cyber mission - the only one where DHS's continuing failure to lead places the nation at risk. DHS's own data shows that, on average, power companies do not discover they have been penetrated for 15 months - enough time for attackers to burrow deep and establish pathways for disrupting and destroying massive generators in case hostilities break out or a non-state actor just decides to cause havoc. DHS has not done well because the skills of the managers and staff are a mismatch for the challenges of industrial control system security. Reorganizing won't help; that's just rearranging chairs on the Titanic. If the Secretary believes the problem is real, he needs an outside oversight board of technical and management wizards who know how those attacks are carried out -- that he charges with questioning strategies and forcing rapid skills improvement for employees and contractors.

DoJ Official Says Cooperation Could Help Thwart Ransomware (June 28, 2016)

Speaking at the Center for Strategic and International Studies (CSIS), assistant US attorney general for national security John Carlin said that improved communication between law enforcement and companies could help thwart ransomware attacks. Carlin said, "As long as people are handling
[ransomware attacks ]
on their own and making payments, we're funding the development of more of these tools and more of these actors."

[Editor Comments ]
(Ullrich): People pay for ransomware for the same reason that they pay ransom in kidnappings: They don't believe law enforcement is efficient in countering the threat fast enough. In order for law enforcement to become relevant to ransomware victims, law enforcement would need to take an active role in helping victims restore operations. For example, law enforcement (e.g DoJ or DHS) would have to assist in the development of decryption tools for various ransomware strains.
(Honan): Ransomware can be prevented by following many simple security principles. The fact that it is so widespread highlights how we have failed as an industry to promote good security hygiene amongst businesses and individuals.

FOIA Improvement Act Becomes Law (June 30 and July 1, 2016)

President Obama has signed the Freedom of Information Act (FOIA) Improvement Act into law. It "codifies a statutory presumption of openness," clarifying the need for agencies to justify their decision to withhold information rather than placing the burden of justification on the entity making the request. The bill also places a 25-year limit on the length of time agencies may keep internal deliberations confidential, and it requires the Office of Management and Budget (OMB) to create a single-access website for making FOIA requests.

[Editor Comments ]
(Pescatore): FOIA is about 50 years old now and it was one of the early examples that proved "security through obscurity doesn't work." For the actual sensitive stuff, just saying "we won't mention it" never works - and in the long run it doesn't work for the weak and squishy and embarrassing stuff, either. Over 100 years ago Supreme Court Justice Louis Brandeis said "Sunlight is said to be the best of disinfectants; electric light the most efficient policeman" - of course, now we know that ultraviolet light and other new technologies are even *better* but the principle still holds.

Vulnerabilities in Siemens SICAM PAS (July 5, 2016)

The US Industrial Control System Computer Emergency Response Team (ICS-CERT) has issued an advisory warning regarding a pair of vulnerabilities in Siemens's SICAM Power Automation System substation control software. According to a Siemens advisory, a fix is currently available for one of the two flaws; a fix for the second is in development.

[Editor Comments ]
(Murray): Most vulnerabilities have "work-arounds." Vendors and others need to be identifying and publishing these while awaiting "patches."

Lenovo ThinkPad Firmware Exploit (July 3 and 4, 2016)

A privilege elevation vulnerability in a Unified Extensible Firmware Interface (UEFI) could be exploited to disable firmware write protection on Lenovo ThinkPads. The issue may affect other devices as well, because the problem lies in code that came from Intel. The ThinkPwn exploit takes advantage of a driver that could allow "execution of code in system management mode (SMM) ... with local administrative access." Lenovo is working on a fix.

[Editor Comments ]
(Ullrisch): This vulnerability very likely affects systems well beyond ThinkPad's and Lenovo. The code in question was derived from Intel's sample code, and the company that wrote this part of the BIOS (not Lenovo) likely delivered the same code to other OEMs as well. Watch for firmware updates and apply them soon. This vulnerability would allow an attacker to gain persistent access to a compromised system by overwriting the firmware.
(Williams): Lenovo is relying on code written by another organization, but it suffering all of the bad PR. You can delegate authority but never responsibility.

Qualcomm Processor Flaw Affects Android Phone Encryption (July 1 and 4, 2016)

A flaw affecting some Qualcomm Snapdragon processors in Android phones could be exploited to break full disk encryption. The problem lies in a flaw in the TrustZone within the Qualcomm processor's kernel. The problems were patched in January and May of this year, but not all Android devices have received the update.

LizardStresser Botnet (June 30 and July 2, 2016)

The LizardStresser botnet has been used to launch 400Gbps distributed denial-of-service (DDoS) attacks against websites using bandwidth of compromised Internet of Things (IoT) devices. The number of LizardStresser command-and-control servers has grown recently, likely because the botnet source code was made public last year.

[Editor Comments ]
(Honan and Murray): We are going to see a significant increase in insecure devices on the Internet thanks to the Internet of Things. In the rush to get products to market many vendors are overlooking simple and basic security principles. This will be further compounded when these devices need to have a security update applied as many consumers won't have the skills or the inclination to do so. The answer to this does not rely on the consumer having to learn how to secure their devices but on responsibility and liability for insecure devices being placed squarely on the shoulders of the vendors.

Two-Hour Cyberattack Turnaround for Clearinghouses and Payment Systems (June 29, 2016)

The Committee on Payments and Market Infrastructures (CPMI) and the International Organization of Securities Commission (Iscso) have published cyber resilience guidelines for the world's financial market infrastructures. The guidelines require that by June 2017, payment systems and financial clearinghouses establish plans for restoring core operations from cyberattacks within two hours.

[Editor Comments ]
(Honan): Anyone responsible for high availability systems and/or networks should read the IOSCO Guidance on Financial Resilience for Financial Market Infrastructures as many of the principles outlined are applicable across various industries and not just financial clearing systems.

Additional excellent resources on the ENISA website at
-https://www.enisa.europa.eu/
(Northcutt): The "two hours" is significant because it appears to be the only hard and fast metric in the document. Most of the recommendations are cast as "should" and "may" and that means you can't reliably reach the requirement of a two-hour return to operations.
(Ullrich): This goal sounds very ambitious. A rushed restoration plan could in some cases lead to incomplete containment of the threat and lead to further service interruption.
(Pescatore): The IOSCO guidance report is pretty much YALLOSTTD - Yet Another Long List of Security Things to Do, layered across the usual Protect/Detect/Respond timeline. The 2-hour goal for restoration is a good thing - whether 2 hours is too long/too short isn't as important as at least having a measurable and consistent metric on that. They should have agreed on a similar number for Time to Detect, which is one of the biggest drivers in Time to Restore.
(Williams): Cost and time to recover from an incident is directly proportional to the time that an attacker is allowed to dwell in the network before detection. Organizations should focus first on detection since recovery only begins after detection occurs.

SQLite Patch (July 4, 2016)

Open source database project SQLite has released a security update to fix a problem in the way it creates tempfiles. Because the tempfiles are created in a directory with incorrect permissions, SQLite libraries could leak data and behave in other unsafe ways.

[Editor Comments ]
(Williams): Although SQLite is used and embedded in many applications, this vulnerability is unlikely to be exploited in any practical setting. The vulnerability is only exploitable when none of /tmp, /var/tmp, and /usr/tmp are set to have read, write, and execute permissions (a non-default configuration). Even then, exploitation is complex.

Satana Ransomware Encrypts Master Boot Record (June 29 and July 1, 2016)

Ransomware known as Satana encrypts not only user files, but also the computer's master boot record (MBR), which makes it impossible to load the operating system. According to Malwarebytes, Satana is still under development. It is the second known strain of ransomware that targets MBRs; the first was Petya, which was detected in March.
