Governo promete para breve avanços na criação do Centro Nacional de Cibersegurança

Governo promete para breve avanços na criação do Centro Nacional de Cibersegurança: Está em fase final de apreciação o processo que levará à constituição de um Centro Nacional de Cibersegurança e a "breve trecho" serão aprovadas medidas em Conselho de Ministros para dar seguimento ao processo. A garantia foi deixada hoje por Luís Marques Guedes, secretário de Estado da presidência de conselho de ministros.



Questionado pelo TeK relativamente aos ataques ontem revelados pela Kaspersky a várias entidades públicas, incluindo em Portugal, o responsável não deu detalhes sobre o impacto do ataque considerado pela empresa de segurança como altamente sofisticado.



No entanto, garantiu que o tema da cibersegurança tem estado na agenda do Governo e que o processo de constituição de um Centro Nacional de Cibersegurança continua em marcha, dando seguimento ao trabalho realizado pela comissão instaladora nomeada para definir a estrutura do novo centro.



O Centro Nacional de Cibersegurança é uma das peças da Estratégia Nacional de Segurança da Informação que tem vindo a ser definida pelo Governo. A sua constituição foi anunciada em fevereiro do ano passado, com a indicação de que a estrutura seria lançada no prazo de um ano.



Em abril o Governo anunciou a nomeação de uma comissão instaladora que, até junho, tinha de apresentar um modelo e todas as medidas e instrumentos necessários à respetiva implementação.



Desde então não foram comunicados novos avanços no processo. Na Agenda Portugal Digital, apresentada no final do ano, prevê-se contudo a criação de "um centro de reporte de incidentes e de gestão de situação operacional agregada das redes e serviços de comunicações eletrónicas", mas a medida só está prevista para 2016.



Recorde-se que ainda no início do mês a Comissão Europeia revelou os traços gerais de uma nova estratégia de cibersegurança para a região.



Uma das medidas previstas é a definição, em todos os países da União, de uma entidade responsável pela estratégia de cibersegurança. A estrutura deve ser dotada de meios e recursos financeiros próprios e atuar ao nível da prevenção e resposta aos riscos e incidentes de segurança detetados.

IBM Patented a One Atom-Thick Graphene Transistor That Works 1,000 Times Faster Than Silicon

IBM Patented a One Atom-Thick Graphene Transistor That Works 1,000 Times Faster Than Silicon:

Next stop, the singularity. IBM has just won a patent for a brand new single atom graphene transistor that will allegedly “transmit electrical pulses 1,000 times faster than silicon.” And if that doesn’t give rise to ultra-intelligent, super-efficient autonomous A.I., then man, I don’t know what will.
The tech blogs are heralding the patent as a lifeline for Moore’s law, which for decades now has correctly described the fact that the number of transistors we can fit on a computer chip has doubled every two years, allowing them to get faster, faster.
IBM took to its Tumblr to celebrate the patent, giving itself a pat on the back/PR blast and claiming that this “could give a jolt to the rate that our computers and electronics improve—and uphold Moore’s Law for decades to come.”
Here’s the abstract of patent #8,344,358 in full:
A graphene-based field effect transistor includes source and drain electrodes that are self-aligned to a gate electrode. A stack of a seed layer and a dielectric metal oxide layer is deposited over a patterned graphene layer. A conductive material stack of a first metal portion and a second metal portion is formed above the dielectric metal oxide layer. The first metal portion is laterally etched employing the second metal portion, and exposed portions of the dielectric metal oxide layer are removed to form a gate structure in which the second metal portion overhangs the first metal portion. The seed layer is removed and the overhang is employed to shadow proximal regions around the gate structure during a directional deposition process to form source and drain electrodes that are self-aligned and minimally laterally spaced from edges of the gate electrode.
And one of the renderings filed:


Figure 1 is a "vertical cross-sectional view of an exemplary structure after formation of a graphene layer," which would appear to be the top layer, while figure 1A is a bird-eye view of the same structure. It appears that IBM expects a graphene chip to be a multi-layer device–which makes sense considering the graphene layer is only an atom thick–but it's in the graphene layer that the magic happens. The properties of graphene allows for the creation of what are called graphene field effect transistors, which (this is hopelessly simplified, of course) are powered by self-aligned electron gates that can work at extremely high frequencies—as high as 100 GHz, according to the filing, although there are still technical challenges to get to that point sustainably.
Nonetheless. I am suddenly painfully aware of how crappy and insufficient my 2010-era processing power is, now that I know it could be going 1,000 times faster. I am still aware of page load times, and it is already 2013. What a gyp.
Most of us can hardly even conceive of what a computer that fast might possibly be able to do, especially for humble consumer purposes. Guess we’re going to find out, tho—fingers cross for something closer to legit AR utility on mobile devices or gonzo VR fun and further from autonomous robo-domination. Either way, things are going to get interesting.

The New $20 Nokia Phone’s Battery Lasts a Month, Is Ideal for Post-Apocalyptic Environs

The New $20 Nokia Phone’s Battery Lasts a Month, Is Ideal for Post-Apocalyptic Environs:

When the lights go out, and the whole of human civilization is plunged into a pre-industrial dystopia, there are three gadgets above all that science fiction has definitively proven we’ll need:
1. A flashlight
2. A means of durable long-distance communication
3. A radio, to search for signs of distant life, naturally.
At a cost of just $20, the new Nokia 105 rolls all three into one. It is the first bona fide anti-zombie apocalypse mobile phone. It will be the Finnish telecom giant’s cheapest offering yet, and its battery will last up to a month on standby on a single charge—when the outlets are dry, your iPhone is useless in like 8 hours, even if you’re not playing Angry Birds.
The 105 also comes equipped with a flashlight and an FM radio, though no internet access. Clearly, it is a worthy investment for zombie-fleeing humans everywhere.

However, in these pre-apocalyptic times, Nokia is targeting a different demographic—the 2.7 billion people in China, Indonesia, India, and Africa the company estimates do not yet own a mobile phone at all.
CNET gives the phone a pretty favorable review, generally praising its functionality given the rock-bottom price, and noting that it’s expressly designed to persist in non-urban environments: “fewer joints and openings also do a better job protecting internals from the elements.” The cheap phones may prove to be a boon for modernizing economies, if service plans can be held in check and kept affordable.
Meanwhile, advanced societies have come to rely on the rapid information exchange enabled by mobile phones—and as we’ve seen, it doesn’t take total Armageddon to throw them into dysfunction. Hurricane Sandy showed how even denizens of the highest-tech cities in the world can easily be thrown into disarray, basic services going unprovided, forced into forming massive queues in coffee shops and department stores if the lights go out. And as long as we continue to rely on old-fashioned, centralized power, those lights are at constant risk of going out—whether from extreme weather events or, someday, hackers.
As such, keeping an additional phone around the house, for use in case of an incipient dystopia, long suggested by (surprise) phone companies and tech pundits, is looking like an increasingly pragmatic idea. Can’t say the new Nokia phone will actually do the trick, as I haven’t yet actually seen one outside of a screenshot. But I’d be glad to have light, radio, and a month-worth of phone availability when the power goes out and the warlords show up.

The gaping hole in Obama's plan to stop Chinese hacking

The gaping hole in Obama's plan to stop Chinese hacking:
http://en.wikipedia.org/wiki/United_States
The word “China” appears 120 times in the Obama administration’s just-released report, “Administration Strategy on Mitigating the Theft of U.S. Trade Secrets,” on combatting cyber-espionage against U.S. business. Of course, Chinese hacking is a threat to more than just American businesses: the Washington Post reports today that just about every powerful institution in the District, from federal agencies to think tanks to, yes, media organizations “have been penetrated by Chinese cyberspies.”

Contribuintes pedem faturas em nome de membros do governo

Contribuintes pedem faturas em nome de membros do governo:
Anda a circular pela Internet uma lista com diversos números de identificação fiscal de membros do atual governo. O objetivo desta "partida" é incentivar os contribuintes a passarem as suas faturas com os dados, em forma de protesto.

Nos últimos dias tem circulado, por mensagens de telemóvel, email e pelas redes sociais, uma lista com alguns dos números de identificação fiscal (NIF) de membros do governo, como Paula Teixeira da Cruz ou Pedro Passos Coelho. A iniciativa serve para incentivar os utilizadores, que são contra as multas a aplicar a quem não pedir fatura, a fazê-lo mas em nome de um ministro, para levar a uma eventual investigação às suas contas.

Tal acontece porque os prestadores de serviços de restauração, por exemplo, (entre outros serviços sujeitos a IVA), têm de emitir a fatura com os dados dos contribuintes, mas não têm forma nem competência para fazer a fiscalização dos mesmos. Esta "partida" não é, no entanto, isenta de responsabilidades. Dar o número de outra pessoa pode constituir, afinal de contas, um crime de falsas declarações.

Esta "rebeldia" dos contribuintes surge após a entrada em vigor da obrigatoriedade de emissão de faturas, em janeiro, com multas para quem não o faça. Desta forma, as faturas são, de facto, pedidas, mas em nome de um político e não em nome próprio. Para além disso, diz a mensagem que circula pela Net, se o valor das faturas apresentadas em nome de, por exemplo, Vítor Gaspar, for superior aos seus rendimentos, este poderá vir a ser alvo de uma investigação executada pelo Fisco.

A ideia parece ter surgido de um movimento independente de cidadãos com presença assídua nas redes, o movimento Revolução Branca, e espalhou-se um pouco por todo o lado. Segundo divulga o semanário Sol, o Sindicato dos Trabalhadores dos Impostos já terá mesmo tido conhecimento deste "passa-a-palavra" há pelo menos duas semanas.

Scammers Extort BitTorrent Users Posing as Law Enforcement

Scammers Extort BitTorrent Users Posing as Law Enforcement:
Over the years we have seen plenty of scam artists trying to make a few bucks off BitTorrent users and other file-sharers, but the stunt that’s being pulled off by the “Internet Copyright Law Enforcement Agency” tops them all.
Disguised as copyright trolls, the unregistered outfit is targeting file-sharers across the United States with copyright infringement claims and threats of criminal prosecution.
Victims of the scheme receive a letter in which they are notified about alleged copyright infringements that took place through their Internet connection. The letter is sent to their home address and lists an IP-address and the files that were downloaded without permission.
“We work with law enforcement agencies and strategic partners around the world to enforce copyright laws, and to help prosecute individuals and companies who violate these laws,” the group introduces itself in the letter.
To escape civil and criminal prosecution the account holder is asked to settle the issue for $495, or else. Others report slightly lower claims but the threats are the same. Pay up now or you might face criminal action and millions of dollars in fines.
“You may face serious potential criminal and/or civil charges filed against you. If you are arrested for felony criminal copyright infringement you will be fingerprinted, photographed, and held in jail until you are arraigned in court,” the letter reads.
“If you act promptly you will help avoid being named as a Defendant in a potential criminal and/or civil lawsuit that can result in a felony criminal conviction causing imprisonment, and/or fines of up to several million dollars,” it adds.
The company suggests that it works with law enforcement and represents a wide variety of copyright holders, including popular artists such as Skrillex and Cee Lo Green, but it appears that the company is just acting on its own.



Internet Copyright Law Enforcement Agency

According to information obtained by SJD the accusations are not made up. This means that the IP-addresses were indeed “caught” sharing the files listed in the letter. However, it is a mystery how the “Internet Copyright Law Enforcement Agency” obtained the home addresses of the subscribers.
Regular copyright trolls get the subscriber information through a subpoena they obtain from court, but there is no sign of any legal action tied to these claims.
This leads us to worrying possibility that the “Internet Copyright Law Enforcement Agency” may have contacts working at one or more Internet Providers. These would be able to look up the addresses of the account holders in question, bypassing the legal system.
As can be seen from the image below the company urges their victims to send money to a virtual office in Washington. However, the company itself doesn’t appear to be registered under the name it’s using.



Pay up
payup

Although the scale of the scam is unclear, several letter recipients have posted messages on the Internet in recent days. While some people appear to recognize it as a scam, there are probably many more who didn’t, and paid up.
As it turns out, however, all signs indicate that the “Internet Copyright Law Enforcement Agency” are the criminals here, possible facing several years jailtime for fraud, extortion and racketeering. That is, if they are caught and convicted.
Interestingly enough, the public attention seems to have frightened them, as a few hours ago they suddenly claimed to have ceased their operations.
“Effective immediately, the Internet Copyright Law Enforcement Agency has ceased operations. Please disregard any notices you received from us, and please do not send us any payments,” a message on their website reads.
While this is good news for the people who still have to pay up, the persons behind the scheme shouldn’t be able to get away with this so easily. We encourage everyone who received a letter to contact the police and their Internet provider, urging them to look into the matter.
