DHS to Offer Cybersecurity Salary Incentives for New Hires (May 3, 2016)

The US Department of Homeland Security (DHS) is expanding a program that offers bonus pay to attract talented cybersecurity employees to government positions, which traditionally pay less than private industry. The bonus program was piloted at the DHS's National Protection and Programs Directorate (NPPD) and will now be available to "the rest of its headquartered elements."
-http://federalnewsradio.com/cybersecurity/2016/05/dhs-sweetens-cyber-workforce-r
ecruiting-new-bonuses/

[Editor's Note (Henry): The salary incentives offered here by DHS are valuable, in principle, but they need to be administered in a way that is both effective and consistent. I've seen similar government programs where people are put into a certain category because they've got the proper "credentials" check mark, but not necessarily the required experience or skillset. This has the potential to create a division in the ranks, whereby those who are already doing the job successfully but don't have the requisite accreditation are underpaid, while those brought in because they fit the bill on paper, but don't always have the full capabilities as others are more highly compensated. Certifications are a good start, but incenting employees based on actual skills, real-world experience, technical prowess and successful results is critically important. (Paller): Echoing Shawn Henry's remarks (recalling that he ran the cyber division at the FBI where technical skills' excellence mattered), DHS's bonus program will be a grave error if the certifications it uses measure the ability to talk about security rather than the hands-on skills needed to fix the problems or show organizations how to fix them. DHS has a history of misusing cybersecurity hiring authorities to hire general purpose IT people. If DHS misuses this new authority to reward people who can admire the problems but don't have the skills to correct the problems, Secretary Johnson should be called before Chairman Issa's Committee for an even tougher grilling than the one given to the OPM chief after the breach that hit her agency. (Pescatore): When I graduated college with an Electrical Engineering degree, NSA had salary incentives for EEs. The 25% increase made the grade 7 salary competitive with private industry back then. But, as this article notes, DHS really needs to look at why their turnover seems to be so high. Keeping good security people is probably more critical than hiring new college grads and giving them on the job training just to see them go to other agencies or private industry. ]

Critical Flaws in ImageMagick (May 4, 2016)

Critical vulnerabilities in the widely used ImageMagick image-processing library could be exploited to execute code hidden in malicious images. A proof-of-concept exploit has been released, but there are currently no patches available. ImageMagick developers have recommended using a policy-based mitigation until a fix is released.

ImageMagick Policy Mitigation Information:
-https://www.imagemagick.org/discourse-server/viewtopic.php?f=4&t=29588
[Editor's Note (Liston): These vulnerabilities allow four different types of remote exploitation: code execution, file deletion, file moving, and file content disclosure. Looking at the code, ImageMagick is really just a set of command-line tools and the various "libraries" are, essentially, wrappers for running the command-line stuff. Expect that there will be many more vulnerabilities discovered in ImageMagick now that it has garnered so much attention. (Williams): The challenge with this vulnerability will be locating all of the impacted applications. ImageMagik is usually installed on the system as part of another application to provide library support rather than as a standalone application. System owners, particularly those with Internet facing web applications, should contact their vendors and ask if they are vulnerable. If so, schedules for patch release and any mitigation steps should be discussed. (Ullrich): If your web sites processes images, you are likely vulnerable. This is a "must patch" vulnerability. Luckily, there is a workaround that you can apply by adjusting configuration files for ImageMagick. ]

Serious Flaw Affects Android Devices with Qualcomm Chips (May 5, 2016)

A vulnerability in Android devices with Qualcomm chips could be exploited to expose users' data. The flaw was introduced five years ago in a set of APIs for Qualcomm's "network_manager" system service. While Qualcomm has released fixes and notified customers, the original equipment manufacturers must release patches, which means that many devices will not be patched.

Cisco Updates TelePresence, FirePOWER, and Adaptive Security Appliance (May 5, 2016)

Cisco Systems has released a fix for a critical flaw affecting its TelePresence videoconference systems. Cisco also released fixes for vulnerabilities in FirePOWER and Adaptive Security Appliance devices. The TelePresence update addresses a flaw that could be exploited to allow remote code execution. The FirePOWER and Adaptive Security Appliance updates address flaws that could be exploited to trigger denial-of-service conditions that crash the devices.

Apple Updates Xcode Development Tool (May 5, 2016)

Apple has updated its Xcode git implementation to address a pair of critical flaws that could be exploited to allow remote code execution. The update for OS X El Capitan v10.11 and later is Xcode version 7.3.1.

[Editor's Note: (Ullrich) Very much overdue. This vulnerability has been known for several months. Apple keeps delaying these updates to open source software it includes. ]

Microsoft Security Intelligence Report Includes Cloud Data (May 5, 2016)

According to Microsoft's most recent Security Intelligence Report, cybercriminals are becoming faster and more efficient at launching attacks. However, the number of ways they use to compromise computers has not grown much. The report, which covers the second half of the 2015 calendar year, also notes that "high severity vulnerability disclosures were up more than 40%." This iteration of the report marks the first time Microsoft has incorporated security data from its cloud services.

n-malicious-login-attempts-in-2015/

Microsoft Security Intelligence Report:
-https://www.microsoft.com/security/sir/default.aspx
[Editor's Note (Pescatore): I've been reading Microsoft's SIR reports for close to 10 years now and there is always great data, once you get past the increasing amount of "Here's how Microsoft software (and now cloud services) protects you against attacks against vulnerabilities in Microsoft software...") Two consistent observations I make: (1) For the past several years, the most commonly exploited Windows vulnerabilities have had patches that came out in 2009 and 2010, pointing out old versions of IE still in use and/or just really, really bad patching.; and (2) if Windows had an App Store or Google-play like mechanism built in like the iOS and Android whitelist feature, most of the data would go away because 99% of the malware wouldn't have had any impact. (Murray): No new attack vectors are needed. As long as "Social Engineering," bait attacks, particularly "phishing," continue to work so well, no new methods are needed. It used to be that bait appealed to the "Seven Deadly Sins," but curiosity and familiarity seem to work even better. That said, yesterday I got an e-mail that combined curiosity with fear of the IRS. ]

OpenSSL Update Fixes Six Security Issues (May 3 and 5, 2016)

The OpenSSL project has released an update that patches six vulnerabilities in the open-source cryptographic library. Two of the flaws are rated critical; one could be exploited to decrypt login credentials, the other to execute malicious code. The updated versions of OpenSSL are 1.0.1t and 1.0.2h.
-https://isc.sans.edu/forums/diary/OpenSSL+Updates/21015/
-http://www.eweek.com/security/openssl-patches-six-vulnerabilities.html
-http://arstechnica.com/security/2016/05/aging-and-bloated-openssl-is-purged-of-2
-high-severity-bugs/

[Editor's Note (Murray): "Open Source" is failing to produce the improvement in quality promised by its proponents. Developers continue to incorporate code without inspecting it or determining its quality or suitability for their application. In complex areas like cryptography or even mathematical functions, they may not be competent to judge. We need research into and documentation of "strength of (software engineering) materials." ]

Locky Command-and-Control Server Breached (May 5, 2016)

Someone gained access to a command and control (C&C) server for Locky ransomware and exchanged the malicious payload for a benign file that displays the message, "Stupid Locky." Earlier this year, a Dridex C&C server was similarly compromised.
-http://www.darkreading.com/endpoint/stupid-locky-network-breached/d/d-id/1325421
?

-http://www.theregister.co.uk/2016/05/05/locky_ramsomware_network_hacked/
[Editor's Note (Honan): While some may welcome this type of "vigilante" approach, we need to be wary that C&C servers can hold very valuable intel and information for Law Enforcement Agencies. Compromising such systems could in turn compromise potential evidence that LEA may require to charge a suspect or such a compromise could disrupt a LEA led operation against those behind the C&C. ]

Michigan Company Loses US $495,000 to Transfer Fraud (May 3 and 5, 2016)

A Troy, Michigan investment company recently lost US $495,000 to email fraud. An employee at Pomeroy Investment Corp. received an email that appeared to be from another employee, directing them to transfer the funds to a bank in Hong Kong. The company did not realize that the transfer request was fraudulent until days later.

tment-company-hacked/83879240/

-http://www.scmagazine.com/spearphishing-attack-nets-495k-from-investment-firm/ar
ticle/494645/

[Editor's Note: (Ullrich): This is a pretty modest sum compared to other business e-mail compromises. In particular if your business uses web based / cloud based email systems like Office365, simple phishing is usually used to obtain email credentials, and these services should be used only with two factor authentication. ]

Gozi Malware Creator Sentenced (May 4, 2016)

Nikita Kuzmin, the man who is believed to be the developer behind the Gozi malware, has been sentenced to time served, 37 months, and ordered to pay nearly US $7 million in damages. Gozi spread through maliciously crafted .pdf documents that arrived as email attachments. Gozi harvested online bank account access credentials. One other person associated with Gozi has been sentenced, and another has been arrested in Romania and is awaiting extradition to the US.
