Os M/RQ-4 não são considerados stealh, embora tenham recebido camadas RAM nos últimos anos.

O UAV stealth de reconhecimento que os americanos empregam é o Lockheed Martin RQ-170 Sentinel.

Piorou então, pois se não me engano foi esse que os Habibs levaram pro chão sem sequer precisar atirar, supostamente hackearam o bicho e parece que andaram copiando, inclusive. E a questão permanece: se ele era stealth (e bem menor que os Triton/Night Hawk, aliás), como pôde ser detectado para depois ser hackeado?

Sigo em dúvida sobre que tipo de garantia poderia haver para operar F-35 num espaço aéreo tão bem defendido...

US launched cyber attack on Iranian rockets and missiles – reports
Targeted strike on computer-controlled weapons of Iran’s Islamic Revolutionary Guard had been planned over weeks

The US military launched a cyber-attack on Iranian weapons systems on Thursday, according to sources, as President Donald Trump backed away from plans for a more conventional strike in response to Iran’s downing of a US surveillance drone.

The hack disabled Iranian computer systems that controlled its rocket and missile launchers, two officials told the Associated Press, and were conducted with approval from Trump. A third official confirmed the broad outlines of the strike. All spoke on condition of anonymity because they were not authorised to speak publicly about the operation.

Two of the officials said the attacks, which specifically targeted computer systems of Iran’s Islamic Revolutionary Guard Corps (IRGC), had been provided as options after two oil tankers were bombed. The IRGC has been designated a foreign terrorist group by the Trump administration.

Spoiler!

Over the past year US officials have focused on persistently engaging with adversaries in cyberspace and undertaking more offensive operations.

Trump: I'll be Iran's 'best friend' if it acquires no nuclear weapons

Tensions with Iran have escalated since the US withdrew last year from the 2015 nuclear deal with Iran and began a policy of “maximum pressure”. Iran has since been hit by multiple rounds of sanctions.

Tensions spiked this past week after Iran shot down an unmanned US drone – an incident that nearly led to a conventional US military strike against Iran on Thursday evening.

The cyberattacks are the latest chapter in the US and Iran’s ongoing hacking of each other.

In recent weeks hackers believed to be working for the Iranian government have targeted US government agencies, as well as sectors of the economy including finance, oil and gas, sending waves of spear-phishing emails, according to representatives of cybersecurity companies CrowdStrike and FireEye, which track such activity. This new campaign appears to have started shortly after the Trump administration imposed sanctions on the Iranian petrochemical sector this month.

It was not known if any of the hackers managed to gain access to the targeted networks.

“Both sides are desperate to know what the other side is thinking,” said John Hultquist, director of intelligence analysis at FireEye. “You can absolutely expect the regime to be leveraging every tool they have available to reduce the uncertainty about what’s going to happen next, about what the US’s next move will be.”

The Department of Homeland Security said in a statement released on Saturday that its agency tasked with infrastructure security has been aware of a recent rise in malicious cyber activities directed at US government agencies by Iranian regime actors and proxies.

The National Security Agency would not discuss Iranian cyber actions specifically, but said in a statement to the AP on Friday that “there have been serious issues with malicious Iranian cyber actions in the past”.

“In these times of heightened tensions, it is appropriate for everyone to be alert to signs of Iranian aggression in cyberspace and ensure appropriate defences are in place.”

O Irã é um dos países que possuem forças de guerra cibernética (ou coisa similar) e eletrônica com elevada capacidade de defesa e ataque. Os casos de iranianos que sequestraram drones, embaralharam e furaram os sistemas de comunicações, drones iranianos que penetraram as defesas de navios e bases norte-americanos tem aos montes e não por sorte. Eles sabem o que estão fazendo. Dizem que os chineses e russos conseguem fazer o mesmo ou mais.

Afinal o Trump não atacou é um basófias.
Já estava tudo preparado para o chamar de tresloucado.....
.Oh!!! Que pena. Não tem mais uma guerra para comentar!

Não se trata disso, meu caro DSA (pelo menos de minha parte). O problema é o de sempre, o pessoal é tipo Prepe (el-moiro samdeo, immigo iurado de o nomme christom ), postam mais com o fígado do que com visão geopolítica. O Trump está fazendo a dele, tentando o impossível, que entre outras coisas é conter a alta inevitável do petróleo; fazer o que a Hillary ou qualquer outro político dos EUA faria, ou seja, encher as moirarias de mísseis e bombas, não ajudaria muito nisso, penso...

Bourne escreveu: Ter Jun 25, 2019 9:29 am A realidade é que o Trump percebeu que Guerra não serve para eleger ou reeleger político nos EUA. Ele detonou a Hillary nesse ponto. Não duvido que o tal cancelamento foi planejado para ter impacto na mídia.

E digo mais, se na campanha algum candidato democrata (Biden, talvez) nos debates interpelar o Trump sobre a covardia de não atacar o Irã decreta a própria derrota. Porque basicamente assume que começaria uma guerra contra o Irã.
