IBM now has 18 quantum computers in its fleet of weird machines

(May 6, 2020)

Eighteen quantum computers might not sound like a lot. But given that each one is an unwieldy device chilled within a fraction of a degree above absolute zero and operated by Ph.D. researchers, it’s actually a pretty large fleet. In comparison, Google’s quantum computers lab near Santa Barbara, California, has only five machines, and Honeywell only has six quantum computers.

Intel hatte einen Datenreichtum…

(…) Vielleicht könnte man das ja mal als Anreizs sehen, eine konkurrenzfähige offene Architektur ohne Geheimnisse zu bauen. In Europa am besten. Bzw. eigentlich mit dem Geld von Europa aber nicht in Europa, sonst kommen wieder die Schweine, äh, die Innenminister.

Habt ihr euch Intel Cascade Lake Prozessoren gekauft, um nicht mehr von ZombieLoad betroffen zu sein? Dann seid ihr auf Intels Getrickse reingefallen

„Natürlich kann uns Intel nicht sagen, was wir machen sollen. Wir sind eine unabhängige Universität. Aber Intel kollaboriert mit der Uni, finanziert Doktoranden und ermöglicht, dass die Suche nach Sicherheitslücken an der Uni stattfinden kann. Als unabhängige Universität fragen wir uns allerdings schon, warum das Embargo so lange dauern muss.“

ZombieLoad Attack: Watch out! Your processor resurrects your private browsing-history and other sensitive data.

After Meltdown, Spectre, and Foreshadow, we discovered more critical vulnerabilities in modern processors. The ZombieLoad attack allows stealing sensitive data and keys while the computer accesses them.

While programs normally only see their own data, a malicious program can exploit the fill buffers to get hold of secrets currently processed by other running programs. These secrets can be user-level secrets, such as browser history, website content, user keys, and passwords, or system-level secrets, such as disk encryption keys.

The attack does not only work on personal computers but can also be exploited in the cloud.

Geopolitics – Huawei ban: Australia becomes increasingly isolated among Five Eyes partners if UK includes Chinese firm in 5G network


The US has urged other Five Eyes members – the UK, Canada, New Zealand and Australia – to exclude Huawei from the construction of new telecommunications networks, claiming the company could provide covert access for Chinese intelligence collection, making secure data vulnerable.

However, if the reports from the UK prove accurate, Australia would stand alone as the only member of the Five Eyes alliance – aside from the US – with an all-out ban on Chinese telecoms equipment. Australia, for its part, on Thursday reaffirmed the ban.

There is mysterious ‘undocumented technology’ hidden on Intel computer chips, researchers say

Computer experts have claimed that the chips which power most of the computers in the world are hiding mysterious and ‘undocumented’ technology.

Analysts from Positive Technologies alleged that Intel chips and processors contain an enigmatic ‘logic signal analyser’ capable of reading ‘almost all data on a computer’.

The claims are likely to alarm conspiracy theorists …

“Some say that because these countries are using Huawei equipment, it makes it harder for US agencies to obtain these countries’ data,” he added.

Mr Xu also revealed that Huawei would spend more than $2bn to restructure the code used in its telecoms services worldwide after a series of “confrontational” meetings with Britain’s cyber security agency over the issue.

Huawei Works With Arm, Not Intel, on New CPU

(7.1.2019) William Xu, director of the board and chief strategy marketing officer of Huawei, noted that Huawei had worked extensively with Intel. But he said a diversity of applications and data is driving varied computing requirements. “Huawei has long partnered with Intel to make great achievements,” said Xu in a statement. “Together we have contributed to the development of the ICT industry. Huawei and Intel will continue our long-term strategic partnerships and continue to innovate together.”

Don’t use Huawei phones, say heads of FBI, CIA, and NSA

During his testimony, FBI Director Chris Wray said the government was “deeply concerned about the risks of allowing any company or entity that is beholden to foreign governments that don’t share our values to gain positions of power inside our telecommunications networks.” He added that this would provide “the capacity to maliciously modify or steal information. And it provides the capacity to conduct undetected espionage.”

Out-of-order execution

The high logical complexity of the out-of-order technique is the reason that it did not reach mainstream machines until the mid-1990s. Many low-end processors meant for cost-sensitive markets still do not use this paradigm due to the large silicon area required for its implementation. Low power usage is another design goal that is harder to achieve with an out-of-order execution (OoOE) design.

A vulnerability in some microprocessor manufacturers‘ implementations of the out-of-order execution mechanism was reported to the manufacturers on June 1, 2017, but which was not publicized until January 2018, …

Die Riesenlücken: Sicherheitslücken in den meisten modernen Prozessoren

(März 2018) Meltdown und Spectre missbrauchen Funktionen, die in Milliarden von Prozessoren stecken: Out-of-Order-Execution (OoOE), Speculative Execution und Branch Prediction. Intel hat OoOE vor rund zwanzig Jahren mit dem Pentium Pro eingeführt: Falls der Prozessor mit der Ausführung eines Befehls warten muss, etwa auf Daten aus dem RAM, verarbeitet er schon einmal einen anderen Befehl, der eigentlich erst später an der Reihe wäre. Er arbeitet Code also nicht in der Reihenfolge ab, wie sie im Programm steht (In Order), sondern in einer anderen, optimierten: Out of Order.

New Spectre attack variant can pry secrets from Intel’s SGX protected enclaves

(2.3.2018) The so-called SgxPectre side-channel attack affects programs with sensitive components protected by Intel’s SGX or Software Guard Extensions enclaves.

SGX is available in newer Intel Core chips and allows developers to selectively isolate sensitive application code and data to run in their own execution environment.

Practical Enclave Malware with Intel SGX

(8.2.2019) Modern CPU architectures offer strong isolation guarantees towards user applications in the form of enclaves. For instance, Intel’s threat model for SGX assumes fully trusted enclaves, yet there is an ongoing debate on whether this threat model is realistic. In particular, it is unclear to what extent enclave malware could harm a system. In this work, we practically demonstrate the first enclave malware which fully and stealthily impersonates its host application. Together with poorly-deployed application isolation on personal computers, such malware can not only steal or encrypt documents for extortion, but also act on the user’s behalf, e.g., sending phishing emails or mounting denial-of-service attacks.

Super-GAU für Intel: Weitere Spectre-Lücken im Anflug

Insgesamt zeigen die Spectre-NG-Lücken, dass Spectre und Meltdown keine einmaligen Ausrutscher waren. Es handelt sich eben nicht um ein simples Loch, das man mit ein paar Flicken nachhaltig stopfen könnte. Es verdichtet sich vielmehr das Bild einer Art Schweizer Käse: Für jedes abgedichtete Loch, tauchen zwei andere auf. Das ist die Folge davon, dass bei der Prozessorentwicklung der letzten zwanzig Jahre Sicherheitserwägungen immer nur die zweite Geige gespielt haben.
