ADSL Router As Effects Pedal

/in


Moore’s law might not be as immutable as we once though thought it was, as chip makers struggle to fit more and more transistors on a given area of silicon. But over the past few decades it’s been surprisingly consistent, with a lot of knock-on effects. As computers get faster, everything else related to them gets faster as well, and the junk drawer tends to fill quickly with various computer peripherals and parts that might be working fine, but just can’t keep up the pace. [Bonsembiante] had an old ADSL router that was well obsolete as a result of these changing times, but instead of tossing it, he turned it into a guitar effects pedal.

The principle behind this build is that the router is essentially a Linux machine, complete with ALSA support. Of course this means flashing a custom firmware which is not the most straightforward task, but once the sound support was added to the device, it was able to interface with a USB sound card. An additional C++ program was created which handles the actual audio received from the guitar and sound card. For this demo, [Bonsembiante] programmed a ring buffer and feeds it back into the output to achieve an echo effect, but presumably any effect or a number of effects could be programmed.

For anyone looking for the source code for the signal processing that the router is now performing, it is listed on a separate GitHub page. If you don’t have this specific model of router laying around in your parts bin, though, there are much more readily-available Linux machines that can get this job done instead.

The Cybersecurity Ripple Effects of the Russia-Ukraine Conflict | Ankura Cybersecurity & Data Privacy

/in


Russia’s invasion of Ukraine has been characterized by strategic and significant use of cyberattacks to support its military objectives. In the days to come, there is likely to be a sharp increase in cyberthreat activity globally and leading organizations must be prepared for the ripple effects that spill out of the conflict.

Throughout the start of 2022, Russia has pressured Ukraine against joining the North Atlantic Treaty Organization (NATO) which would grant them access to powerful military allies. After conducting multiple cyber-attacks against Ukrainian networks, the Russian military is now executing a military assault on Ukraine, invading from multiple directions. This conflict has resulted in a significant increase in cybersecurity threats worldwide and will likely trigger an escalation in cyber-attacks on organizations everywhere. The Ankura Cyber Threat Investigations and Expert Services (CTIX) team is continuously monitoring and analyzing the global cyber threat landscape and is supplying this content to provide specific insights for organizations to help them proactively prepare and be ready to defend their environments and avoid operational disruptions.

How Did Russia Leverage Cyberattacks for its Invasion?

On January 26, 2022, Computer Emergency Response Team of Ukraine (CERT-UA) released a report stating that between January 13th and 14th multiple websites of state organizations were tampered with by Russia, resulting in content alteration and system destruction.[1]  The attack, now known as WhisperGate, gained access through the supply chain, and through the abuse of the vulnerabilities OctoberCMS and Log4j.[2] The malware itself is made up of three components: BootPatch, WhisperGate, and WhisperKill. Similar to the WhisperGate attacks, on February 23, 2022, ESET and Broadcom’s Symantec discovered a second data wiper malware.[3] This malware, dubbed HermeticWiper (KillDisk.NCV), has been used to target hundreds of additional machines. HermeticWiper is a custom application designed to wipe local data, as well as damage the master boot record of the hard drive, preventing the system from booting into the operating system, which is nearly identical to how…

Malawi Household Food Security Bulletin | Mobile Vulnerability Analysis and Mapping (mVAM) on the Effects of COVID-19 in Malawi Round 17: 8th September – 7 th October 2021 – Malawi

/in


SUMMARY OF KEY FINDINGS

  • The food security situation across the country remains stable, with almost all interviewed households classified as having acceptable to borderline food consumption as they consume from the 2021 harvest.

  • The proportion of households who are employing the most severe consumption-based coping strategies remains relatively low, ranging between 19 percent and 21 percent for the current round and the immediate past four rounds, indicating a generally stable food security situation.

  • Physical access to markets has increased slightly, likely due to the decrease in new COVID-19 cases as the third wave of the pandemic dies down coupled with the fact that rural households are still selling their produce from the recent harvest.

BACKGROUND

During this reporting period, Malawi continued experiencing a decline in the number of COVID-19 cases, deaths, and admissions to Emergency Treatment Units (ETUs). As of the last day of this reporting period (7th October 2021), the Ministry of Health indicated that the country registered nine new COVID-19 cases in the past 24 hours, down from 952 cases during the peak of third wave on 22 July 2021.

Cumulatively, Malawi has recorded 61,648 cases, including 2,287 deaths with a case fatality rate at 3.71 percent.
Further, cumulatively, 56,208 cases recovered, with an overall recovery rate of 91.2 percent. Furthermore, on 8th October 2021, the Government announced the continued observance of the COVID-19 restrictions, which include wearing face masks, observing social distancing, and washing hands to prevent the spread of the disease.

METHODOLOGY

Round 17 of remote household-level survey data collection in response to COVID-19 monitoring and seasonal trends in food security took place between 8th September – 7 th October 2021. The survey for this report was conducted using live telephone calls, collecting information from some 2,504 households in all districts and major cities across the country.

The sample size was calculated based on the Integrated Food Security Phase Classification Technical Manual (Version 3.0) guideline of having at least 150 samples per strata. Additional details on this methodology are available in…

Electromagnetic Spectrum Superiority Directorate on boarded into the ISR and Cyber Effects Operations staff > U.S. Air Force > Article Display

/in


ARLINGTON, Va. (AFNS) —  

Headquarters Air Force staff officially transferred the Electromagnetic Spectrum (EMS) Superiority Directorate from strategy, integration and requirements directorate to the intelligence, surveillance, reconnaissance and cyber effects operations directorate Oct. 1.

In conjunction with the directorate move, the EMS Superiority Directorate also absorbed the Air Force Spectrum Management Office (AFSMO) as its fourth division. This move consolidates Electromagnetic Spectrum Operation functions under a single staff – focused on Information Warfare integration efforts across the conflict continuum and is the latest milestone within the Air Force – streamlining oversight, policy and guidance to foster greater collaboration of efforts across various competitive and increasingly dynamic domains.

“It is vital that we leverage, defend and compete across the entire electromagnetic spectrum in order to deliver effects in and through the information environment now and into the future,” said Lt. Gen. Mary O’Brien, deputy chief of staff for ISR and cyber effects operations (A2/6).

Since its inception in 2019, current EMS Superiority Director, Brig. Gen. Tad Clark and his team have been working to ensure the Department of the Air Force is able to “maintain the advantage in the electromagnetic spectrum to stay one step ahead of the strategic competition and maintain freedom of action.”

Air Force Chief of Staff Gen. CQ Brown, Jr. highlighted their work during the Fall 2021 Air Force Association Air, Space and Cyber Conference stating, “I am glad to see the directorate developing the next generation of Airmen and making the changes needed to ensure dominance.”

The Department of Defense published an Electromagnetic Spectrum Strategy (EMSS) in 2020 providing direction and highlighting the importance of EMS superiority in future warfare. Subsequently, the Air Force published its own Electromagnetic Spectrum Superiority Strategy in Apr. 2021.

Following the establishment of the EMSS and the development of the electromagnetic spectrum implementation strategy, Air Combat Command stood up the 350th Spectrum Warfare Wing in June of 2021 to implement EMS…
