TOP OF THE NEWS
OPM: Systems Lacked Logs (June 25, 2015)Investigators say it is difficult to assess the breadth and depth of the attack on OPM's systems and those of its contractors because the agency and the contractors lacked adequate computer logs. The breaches also occurred on the systems of KeyPoint Government Solutions and USIS.
[Editor's Note (Murray): No matter how fast or far the cost of storage falls, IT management continues to believe that it is too dear to use for logs. While the value of logs for forensic purposes is undeniable, Agency leadership does not insist upon them because they might provide unwanted transparency and accountability. ]
OPM: Security Measures Improperly Managed (June 24, 2015)According to the Office of Personnel Management's (OPM's) inspector general, steps the agency was taking to improve the security of its computer systems actually put the systems at greater risk. Someone at OPM decided that the agency's systems needed security management software, but did not choose approved software and did not seek appropriate approval for the acquisition. The software was installed in April, but works on only some of the systems. IG issued a flash audit alert, which was directed to OPM leaders to draw attention to the seriousness of the situation.
[Editor's Note (Pescatore): I don't fault OPM for trying to move quickly after finding out they were compromised, but their after-incident action seems to be as badly misdirected as their pre-incident actions. The most recent OMB FISMA score card had OPM claiming to have 97% of their assets under continuous monitoring. If true, they were obviously monitoring the door to the attic while thieves went in and out the front door. ]

THE REST OF THE WEEK'S NEWS
Cisco Issues Fix for Hardcoded SSH Key Issue (June 25 & 26, 2015)Cisco has pushed out a fix for several security appliances that shipped with hard-coded SSH keys. Cisco's Web Security Virtual Appliance, Email Security Virtual Appliance, and Security Management Virtual Appliance had default keys for remote support access. Versions of those products downloaded before Thursday, June 25, are vulnerable. The fix deletes preinstalled keys. Storm Center:
[Editor's Note (Pescatore): The bad news is there was a big hole in Cisco's security QA process enabling multiple products to ship with hardcoded SSH keys installed. The good news is Cisco's internal security testing found the problem first and better news will be when Cisco fixes the seriously broken process that allow the products to ship. ]
Samsung Disables Microsoft Update (June 24 & 25, 2015)Microsoft has issued a statement "condemning" Samsung's decision to download software that keeps Windows Update from updating in the background on Samsung devices. Samsung maintains that it is simply giving its users "the option to choose if and when they want to update the Windows software on their products."
[Editor's Note (Pescatore): What Samsung did is wrong. But instead of dueling press statements, I'd rather see Microsoft work with the big PC hardware vendors to end this problem of Windows update trashing various drivers. Windows Update has progressed to its own form of bloatware - installing system tray icons to drive adoption of Windows 10, for example.
(Honan): This move by Samsung is bad on so many levels. Undermining the security architecture of an operating system to enable remote support for bespoke hardware drivers is not the way to address the problem. It also raises the question if Samsung can disable the Windows Update service how long will it be before criminals are using the same techniques. ]
BlackShades Purveyor Sentenced to Prison (June 23 & 25, 2015)Alex Yucel has been sentenced to 57 months in US prison for selling the BlackShades remote access Trojan (RAT). Michael Hogue, who was also involved in distributing BlackShades, has pleaded guilty and has not yet been sentenced. Three other people associated with BlackShades have received prison sentences of between one and two years. BlackShades allegedly made its way onto more than half a million computers in 100 countries. People who bought BlackShades used it for a variety of purposes, including spying on people through their webcams, stealing personal data, and locking up computers and demanding ransom.
Call Center Customer Data Breached (June 25, 2015)A computer tech support call center, Advanced Tech Support, has acknowledged that customer data have been misused. Some customers have reported receiving calls that appear to come from Advanced Tech Support; the callers tell the customers that they are eligible for refunds and must allow remote access to their computers. A notice on the company's website said that it "believes it has found the culprit and terminated the responsible party." Last year, the US Federal Trade Commission (FTC) sued Advanced Tech Support and several other companies for allegedly tricking callers into buying phony, overpriced support services and unnecessary software.
Google Removes Eavesdropping Extension from Chromium (June 24 & 25, 2015)Google has removed an extension from its Chromium open source browser that allowed it to continuously listen to the computer's microphone. The extension is called Chrome Hotword and provides functionality for "OK, Google," which lets users search Google verbally.
Dyre an Emerging Threat (June 24 & 25, 2015)According to a report from Symantec, criminals are using Dyre malware to target users of more than 1,000 banks. Calling Dyre an "emerging threat" in the financial fraud landscape, Symantec noted that its use increased significantly following the takedowns of other malware networks, like ZeuS. Dyre has close to 300 command-and-control servers operating largely in Russia and Ukraine; the attacks are focused on computers in other European countries.
[Editor's Note (Northcutt): The Symantec report referenced here is well written, clearly researched, and is not sensational. It answers the awareness program question, "what is in it for me", since it is the individual bank account that is targeted. I just wish that early in the document they would have included a couple of examples of the most successful spam emails. ]
New Zealand Aircraft Grounded for Two Hours Due to Radar System Outage (June 24, 2015)All aircraft in New Zealand were grounded for two hours on Tuesday, June 23 after a radar system failed. The outage kept 200 flights from taking off, and air traffic controllers had to use radio systems to land the planes that were in the air when the system went out. Airways New Zealand COO Pauline Lamb said the problem was caused by equipment failure that prevented data from being sent to air traffic controllers.
Emergency Patch for Adobe Flash (June 23 & 24, 2015)Adobe has released an emergency fix for a critical flaw in its Flash Player browser plugin that is being actively exploited in "limited, targeted attacks." The most up-to-date version of Flash is now 188.8.131.52 for Windows and Mac and 184.108.40.2068 for Linux.
[Editor's Note (Murray): Our continued tolerance for Flash raises the question of whether or not we are serious about infrastructure security and resilience. ]
Some US Navy Workstations Still Running Windows XP (June 23, 2015)The US Navy is still running Windows XP on some of its computers, paying Microsoft millions of dollars in fees to support the retired operating system. The Space and Naval Warfare Systems Command signed a US $9.1 million contract for continued support for Windows XP, Office 2003, Exchange 2003, and Windows Server 2003. The Navy began transitioning to newer operating systems two years ago, but as of last month still had 100,000 workstations running XP and other, outdated software.
[Editor's Note (Assante): Don't be so fast to judge as much of our critical infrastructure and industrial-base continues to run on Windows XP. The good news here is the Navy has planned to receive the necessary support to manage their growing risk. The Navy relies upon a host of industrial control systems for their ships and bases and has begun developing dedicated security programs, new architectures, and capabilities.
(Pescatore): From a security perspective, this is a "plane landed safely" story. The Navy did the right thing and paid for custom support. From a taxpayer perspective, it was a bad IT governance decision to stay on XP. From a security perspective, business said "we have to stay," security side said "it will cost $9M to manage residual risks" and the business side ponied up. When it works right, that is how it goes. ]
LOT Airline Grounding Due to DDoS (June 23, 2015)Polish airline LOT says that the computer problems that grounded its flights over the weekend were due to a distributed denial-of-service (DDoS) attack that prevented flight plans from being delivered on time.
[Editor's Note (Murray): To date, most attacks against infrastructure have been isolated, rather than coordinated, denial of service attacks. While mitigation services are available, they remain expensive and many organizations continue to prefer to just wait them out. It remains to be seen whether or not a well planned and resourceful attack could deny most of the internet service. However, both the Morris Worm and Code Red attacks suggests that it might. We should be taking advantage of the falling cost of hardware to over provision our networks. (To paraphrase Parkinson, traffic will expand to fill the capacity available to carry it.) ]

PESCATORE: HAS MICROSOFT LOST ITS FOCUS ON 'SECURITY FIRST'Back in January 2002, then Microsoft CEO Bill Gates sent one of his annual all-hands emails to all Microsoft employees. This was after the Code Red and Nimda worms had brought down thousands of corporate networks by exploiting continuing streams of vulnerabilities in Windows and Gates recognized Microsoft had to change and focus on what he called "Trustworthy Computing." The part of his email I liked the best was this: "So now, when we face a choice between adding features and resolving security issues, we need to choose security. Our products should emphasize security right out of the box, and we must constantly refine and improve that security as threats evolve."
That memo really did change the direction of Microsoft, and they made huge progress over the past 13 years - and like all software vendors, much more progress can and should be made to make computing safer for users and businesses.
In February 2014 Satya Nadella became CEO of Microsoft, replacing Steve Ballmer. Nadella has put out two all-hands emails to Microsoft employees that have been made public. The first one in July 2014 mentioned security only 8 times, starting with "And we will strike the right balance between using data to create intelligent, personal experiences, while maintaining security and privacy." The needle seemed to be tilting away from security-first and back towards features-first.
This week Nadella sent out another email across Microsoft. There was no mention of security or privacy or trust, not once.
Microsoft has to change and innovate to compete in an IT world where Google and Amazon and Apple are leading the way, but losing that focus on security first should NOT be part of that strategy. All vendors have to listen to their customers - make sure you are telling Microsoft (and every other vendor) you still want them to Choose Security - focus on safety and security and only ship features that are safer and more secure than the previous generation, since the attackers are not standing still.
