WikiLeaks Will Offer Tech Companies Access to CIA Hacking Tools (March 9, 2017)

Julian Assange says that WikiLeaks will offer tech companies access to the technical details of hacking tools in the cache of leaked classified CIA documents so that the companies can address the vulnerabilities the tools exploit. Companies are wary of the offer because of the legal ramifications of accepting stolen classified data.

[Editor Comments]

[Williams] White House press secretary Sean Spicer noted "any individual or entity using any piece of still-classified information" should consult with their legal counsel (clearly a veiled threat). Some people with security clearances I've talked to are afraid to even view the data. This attitude is extremely damaging. Many of those with security clearances are performing cyber threat intelligence functions for our nations most secure networks. Attackers can and will learn from the insights in the CIA leaks. To limit our defender's access to the same data through veiled threats is reckless and further harms US national security.

Critical Flaw in Apache Struts 2 (Patch Now!) (March 9, 2017)

Attackers are actively exploiting a critical code execution flaw in the Apache Struts 2 web application framework to take control of vulnerable webservers. There are at least two working exploits. Developers released a patch for the issue earlier in the week, but not all affected servers have been updated. Organizations that use Apache Struts 2 are urged to upgrade to versions 2.3.32 or as soon as possible.

[Editor Comments]
[Ullrich] Patching this flaw should be your top priority right now. We have observed exploit attempts shortly after the flaw became known. Exploitation is trivial and tools to exploit this problem are readily available. Note that Struts2 can be a component of many Java based web applications (JBOSS, HipChat).

Industry Officials to House Committee: Government is Not Sharing Enough Cyber Threat Info (March 9, 2017)

Tech industry officials testified before the U.S, House Homeland Security Committee's cybersecurity panel, saying that there is an imbalance in threat information sharing between the private sector and the government. Legislation passed in 2015 grants companies protection from legal liability when they share threat information with the government, but the government has been less forthcoming with threat information that could help protect IT systems in the private sector. Intel Security Vice president Scott Montgomery noted that when the government classifies a cybersecurity event, it "restrict[s] the number of people who can lend assistance and... allow[s] the adversary to operate with impunity." Witnesses said that if information about threats could be stripped of identifiable information and provided to members of private organizations who hold security clearances, companies would be better positioned to take action against similar threats.

[Editor Comments]

[Pescatore] his has been the standard complaint about all such government intelligence "sharing" initiatives for over a decade. Many proposals have been put out for how to overcome government worries about exposing sources and methods, but no movement on the govt. side. On the enterprise side, no reason to think this will change any time soon.

[Williams] Over-classification of cyber threat data is a real problem. I've worked incidents where threat data has been shared with federal law enforcement, only to see small portions of that same data shared with a limited distribution community weeks later in "Flash" messages. When we inquired why the most important data we shared with the feds wasn't shared with the broader community, we were told it was classified.

[Northcutt] This is complicated, but also historical. For the last 25 years, the US Government's policy has been, "give us your data and we might share 1% back." If we are talking about a partnership, "that dog don't hunt".

Instagram Phishing Apps Removed from Google Play (March 9, 2017)

13 apps have been removed from the Google Play store after they were found to contain malware that attempted to steal users' Instagram credentials. The malicious apps billed themselves as tools to help increase the number of Instagram followers. Once the attackers obtain account credentials, the compromised accounts could be used to send spam and advertisements and to like and comment on posts from other accounts.

Confide Messaging App Vulnerabilities (March 8 & 9, 2017)

Two separate teams of researchers have found numerous security issues in the Confide messaging app. Confide, which bills itself as "military-grade" with end-to-end encryption, was found to be vulnerable to man-in-the-middle attacks, allowing attackers to intercept and alter communications. Flaws in the app's account management system could be exploited to gain access to user account records. Researchers also found that Confide's screenshot prevention prevention and message deletion features could be defeated. Confide says the flaws have been fixed.

Mozilla Releases Firefox 52 (March 7, 2017)

On March 7, Mozilla released Firefox 52 to fix 28 security issues and add several browser features. Firefox 52 supports the WebAssembly standard. It also disables all plugins that use the Netscape Plugin API (NPAPI) except for Adobe Flash. Mozilla began warning developers and users of the end of NPAPI support in October 2015. Firefox 52 is also the last major version of the browser that will support Windows XP and Vista; future major versions will require Windows 7 or later.

WordPress Updated to Version 4.7.3 (March 7, 2017)

WordPress has updated its content management system (CSM) to version 4.7.3 to address half a dozen security issues and nearly 40 "bugs." This marks the third WordPress update so far in 2017. Three of the six vulnerabilities fixed could be exploited through cross-site scripting (XSS) attacks.

Verifone Investigating Breach (March 7, 2017)

Payment card company Verifone is investigating reports of a breach of its internal networks. The incident appears to have affected several companies that use Verifone's point-of-sale services. (Verifone makes and sells point-of-sale terminals and offers services to support payment card processing.) An internal Verifone memo from January 2017 tells employees to change their passwords within 24 hours and informs them that they will no longer be permitted to install software on company computers.

DHS's Breach Notification Best Practices (March 6, 2017)

The US Department of Homeland Security (DHS) is putting the finishing touches on breach notification guidance for agencies, state and local governments, and other organizations. The DHS Data Privacy and Integrity Committee approved a final draft of the best practices document last month. The guidance addresses deciding whether and how to notify affected individuals; the risks of over-notification; and offers suggestions for additional support for those affected by a breach.

[Editor Comments]

[Pescatore] The draft has common sense recommendations but there are two areas where DHS really ought to go further for government agencies: (1) provide a simplified, standardized risk scoring method for agencies to use in making the notification decision; an d (2) funding an IDIQ kind of contract for some number of approved "identity theft mitigation services." Both of these are needed so that breached agencies can move much, much more quickly in reducing impact to citizens than we've seen them able to move in the past.

[Neely] The draft memo creates a risk based approach, encapsulating lessons learned from the OPM breach and tries to build on the California and other state data breach notification laws enacted since 2003.
