On VOA Radiogram, today’s experiment will involve the audio

frequency of a received MFSK32 transmission.

We hope that simple, receive-only applications (apps) are

developed to decode MFSK32 on PCs and mobile devices. One

requirement of MFSK is that the receiver and software be tuned to

the precise frequency.

VOA Radiogram is typically transmitted on an audio frequency of

1500 Hz. The audio frequency as received tends to be a few Hz

above or below 1500 Hz.

Would an MFSK32 app require an RxID to ensure that the received

audio frequency is exactly correct? Or is there enough tolerance

in MFSK32 that an RxID is not necessary?

Our experiment now begins…

Please now 1) turn off the RxID in Fldigi and 2) set the audio

frequency to 1500 Hz.

Let us know if you are able to decode the following VOA News

story without the assistance of the RxID.

 

The story will begin in ten seconds.

February 27, 2014

The amount of malicious software targeting mobile devices is

exploding, according to security firm Kaspersky Lab.

Kaspersky said that in 2013 « nearly 100,000 new malicious

programs for mobile devices were detected. » That’s more than two

times the number detected the previous year, the company said.

As of January 1, 2014, Kaspersky Lab says it collected 143,211

mobile malware samples.

Rolf von Roessing, the former international vice president of the

Information Systems Audit and Control Association, ISACA, told

information security professionals at the 2013 EuroCACS

information security and risk management conference in London

that a « tidal wave » of threats was emerging against mobile

devices.

Android users are particularly vulnerable, with over 91 percent

of the malware detected targeting the popular mobile operating

system, according to Kaspersky.

« Android is currently more of a target than iOS, but attacks are

happening against Apple mobile devices and, when they are

breached, it is usually fairly serious, » said von Roessing.

Russia leads the world, claiming 40 percent of attacks. India was

second with eight percent of attacks, and Vietnam and Ukraine

were tie for third with four percent of attacks.

« Kaspersky’s findings are consistent with the numbers being

reported by other security vendors in their annual threat

reports, » said Christopher Burgess, CEO of Prevendra a Security,

privacy and intelligence company. « The message? If you are using

a mobile device, keep your operating system up to date, only

download apps from trusted sources, and have in place security

software to protect the content of your mobile device. »

Kaspersky said the vast majority of mobile malware was made with

the aim of stealing people’s money. This kind of malware

increased by a factor of 20, they said. Most of the malware was

designed to phish, steal bank card information or to take money

from bank accounts.

« Today, the majority of banking Trojan attacks target users in

Russia and the CIS, » said Victor Chebyshev, a virus analyst at

Kaspersky in a statement . « However, that is unlikely to last for

long: given cybercriminals’ keen interest in consumer bank

accounts, the activity of mobile banking Trojans is expected to

grow in other countries in 2014. »

Ukraine Says Communications Hit, MPs Phones Blocked

Reuters

March 04, 2014

Ukraine’s telecommunications system has come under attack, with

equipment installed in Russian-controlled Crimea used to

interfere with the mobile phones of members of parliament, the

head of Ukraine’s SBU security service said on Tuesday.

Some Internet and telephone services were severed after Russian

forces seized control of airfields and key installations in

Ukraine’s Crimea region on Friday, but now lawmakers were being

targeted, Valentyn Nalivaichenko told a news briefing.

« I confirm that an … attack is under way on mobile phones of

members of Ukrainian parliament for the second day in row, » the

security chief said at a news briefing.

« At the entrance to [telecoms firm] Ukrtelecom in Crimea,

illegally and in violation of all commercial contracts, was

installed equipment that blocks my phone as well as the phones of

other deputies, regardless of their political affiliation, » he

said.

Ukrtelecom already has said armed men raided its facilities in

Crimea on Friday and tampered with fiber optic cables, causing

outages of local telephone and Internet systems on the continent.

The Ukrainian security chief did not say whether the new issues

were linked to the earlier raid or a separate tampering incident.

Ukrtelecom said it was working on a response to questions from

Reuters about Nalivaichenko’s remarks.

Russia’s domestic intelligence service, the FSB, declined to

comment when asked if Moscow was behind the communications

disruptions in Ukraine.

The main Ukrainian government website http://www.kmu.gov.ua was offline

for about 72 hours after Russian forces seized control of the

peninsula, but went back up early on Monday, said John Bumgarner,

chief technology officer for the U.S. Cyber Consequences Unit.

Bumgarner, whose firm advises companies and government agencies

on how to fend off cyber attacks, said, he is not sure the site

went down as a result of a cyber attack. Still, he said he

believes Moscow has the ability to cause major disruptions using

cyber operations.

« I know they have the ability to do at least as much damage as

they did in Estonia and Georgia, » he said.

Estonia suffered a 10-day attack on its Internet services in

2007, which caused major disruptions to its financial system,

during a spat with Moscow over a Soviet-era war memorial, and

Georgia was hit by mass cyber attacks during a brief 2008 war

with Russia over its pro-Moscow South Ossetia region.

Russian authorities denied direct involvement in both attacks,

saying they had no influence over the actions of self-styled

patriotic hackers.

Is Russia holding back?

Much of Ukraine’s telecommunications infrastructure was built

when it was part of the Soviet Union, along with what is now the

Russian Federation, and is particularly vulnerable to penetration

by Moscow.

« The Russians have the place completely wired, » said Jim Lewis, a

former U.S. foreign service officer and now senior fellow at the

Center for Strategic and International Studies in Washington.

« They are right next door and most traffic has to go through

Russia. That they haven’t done more probably reflects their

confidence that they’re going to come out ahead and there’s

nothing anyone can do about it, » Lewis said.

Cyber warfare experts say that while Russia certainly has the

ability to conduct such campaigns against Ukraine, it has yet to

need to use those capabilities.

« This would show the Russians acting with more discretion and

targeting than recently, » said John Bassett, former head of the

London and Washington stations of GCHQ, Britain’s top secret

government communications center.

« This wouldn’t expose any great depth of their technological

capability and they would be keeping the harder stuff back, » said

Bassett, now associate at Oxford University’s Cyber Security

Center.

Marty Martin, a former senior operations officer with the CIA,

said Moscow likely would only take action to damage Ukraine’s

Internet and internal communications systems if hostilities broke

out.

« A lot of times you don’t want to shut things down. If you do

that, then you don’t get your flow of intelligence. You are

probably better off monitoring it, » Martin said.

Experts believe Russia was behind the hacking of a confidential

phone conversation between senior U.S. State Department official

Victoria Nuland and U.S. Ambassador to Ukraine Geoffrey Pyatt,

which was leaked over YouTube last month.

« Russia’s strategy is control the narrative, discredit opponents,

and coerce, » said Lewis.

Broadcasting Board of Governors seeks comments on the future of

shortwave broadcasting

The Broadcasting Board of Governors (BBG) Special Committee on

the Future of Shortwave Radio Broadcasting is « seeking feedback

from external experts and stakeholders on their perspectives on

the role of shortwave radio broadcasting as a BBG distribution

platform. We are particularly interested to hear views that

consider the evolving media consumption of target audiences,

changing access to shortwave and other platforms, and the need to

prioritize in an austere federal budget environment. »

Shortwave is also specified in the Broadcasting Board of

Governors’ fiscal year 2015 budget request…

WASHINGTON (March 4, 2014) – The Broadcasting Board of Governors

(BBG) today announced its FY 2015 budget request, which will help

U.S. international media meet strategic priorities in light of

dynamic global communications environments and current spending

constraints. …

For the complete BBG press release, see…

http://www.bbg.gov/blog/2014/03/04/bbg-budget-request-tied-to-glo

bal-priorities-and-evolving-media-environments/

The press release is accompanied by this summary…

The FY 2015 request provides $716.46 million for International

Broadcasting Operations. Through this appropriation, the

Broadcasting Board of Governors (BBG) funds operations of its

broadcasting organizations, as well as related program delivery

and support activities. The FY 2015 request provides $4.8 million

in Broadcasting Capital Improvements funding to maintain the

worldwide transmission network of the BBG, including the security

requirements of facilities, maintenance, repairs, and

improvements to existing systems.

The BBG is an independent Federal entity responsible for all U.S.

non-military international broadcasting programs. BBG

broadcasting organizations include the Voice of America (VOA),

Radio Free Europe/Radio Liberty (RFE/RL), Radio Free Asia (RFA),

Radio and TV Marti, and the Middle East Broadcasting Networks

(MBN) – Radio Sawa and Alhurra Television.

The BBG mission is to inform, engage, and connect people around

the world in support of freedom and democracy. BBG radio,

television, and Internet programs reach more than 20 6 million

people each week in 61 languages. By exemplifying free media and

free expression, the BBG helps foster and sustain free,

democratic societies. Those societies have proven to be more

peaceful and stable and rarely threaten their neighbors or offer

safe ha vens for terrorists. Nurturing them is thus a national

security imperative, consistent with the President’s national

security policy.

The FY 2015 Budget Request includes substantial reductions and

investments that rebalance BBG resources away from legacy markets

(in Europe) and platforms (shortwave and medium wave) and toward

current foreign policy priorities (Africa, Asia, and the Middle

East) and modern media platforms (FM radio, television, and

digital). In keeping with this strategy, the request includes

investments to engage audiences in Africa and Southeast Asia,

expand English learning programs, and increase and enhance

social media presence and products. The request also expands on

BBG efforts to transition to digital transmission technology by

continuing to evolve away from shortwave radio transmissions.

The BBG will reduce language service duplication in some markets,

increasing efficiency and boosting impact, by ensuring

coordinated complementary operations and content where two BBG

broadc asters co-exist. To afford some of the proposed

investments and its transition to digital technology, the BBG

proposes targeted significant reductions to administrative costs

and scale back less effective transmissions.

As part of a multi-year strategy to realize efficiencies and cost

savings in its Satellite transmission program, the BBG included a

$29.9 million funding request through the Opportunity, Growth and

Security Initiative. By providing this funding the BBG estimates

savings of 31% in satellite transmission costs over a seven year

period.
