In my opinion, the design of the Samsung Galaxy S21 Ultra is more original and attractive. The camera design makes it more futuristic and it is also more compact than the Galaxy Note 20 Ultra, despite the latter is actually thinner and lighter. The Galaxy S20 Ultra is even more compact, but the design of its camera module is definitely less beautiful.


The most advanced display is offered by the Samsung Galaxy S21 Ultra: there is not a huge difference if we compare it to the Galaxy S20 Ultra and Note 20 Ultra, but it is slightly better. Just like the Note 20 Ultra, even the Samsung Galaxy S21 Ultra supports the S Pen, while the S20 Ultra does not. All the phones come with an in-display fingerprint scanner, curved edges, and a punch-hole design.


In the European variant, the Samsung Galaxy Note 20 Ultra and the S20 Ultra are powered by the same Exynos 990 chipset. But in the U.S. version, the situation is different since the Galaxy Note 20 Ultra is fueled by the Snapdragon 865+, an upgrade of the Snapdragon 865 found on the S20 Ultra. But in each case, the Samsung Galaxy S21 Ultra wins the hardware comparison thanks to even better chipsets: the Exynos 2100 and the Qualcomm Snapdragon 888. Samsung Galaxy S21 Ultra and S20 Ultra pack up to 16 GB of RAM, while you get a max of 12 GB with the Note 20 Ultra.


The worst camera phone of the trio is the Galaxy Note 20 Ultra due to inferior secondary sensors. The Samsung Galaxy S20 Ultra is actually better thanks to a 48 MP periscopic camera with 4x optical zoom and an additional TOF 3D sensor for depth calculation. But the Galaxy S21 Ultra wins the camera comparison with its 10x optical zoom.


Galaxy S21 Ultra provides the longest battery life, followed by the Galaxy S20 Ultra with the same 5000 mAh battery capacity. The Galaxy Note 20 Ultra is a bit disappointing with its 4500 mAh battery. The Galaxy S20 Ultra has faster charging speeds. While you can actually find the Samsung Galaxy S20 Ultra for less than €1000/$900, the Galaxy Note 20 Ultra and the S21 Ultra are priced at more than €1000/$900 even if you look at online street prices. We do not recommend the Note 20 Ultra as its battery is not so satisfying and the S21 Ultra supports the S Pen too. You can go for the S20 Ultra if you want to save money, but you have to say goodbye to S Pen, the higher performance level offered by the S21 Ultra and 10x optical zoom.

Cyberattack exposes lack of required defenses on U.S. pipelines



The shutdown of the biggest U.S. fuel pipeline by a ransomware attack highlights a systemic vulnerability: Pipeline operators have no requirement to implement cyber defenses.

The U.S. government has had robust, compulsory cybersecurity protocols for most of the power grid for about 10 years to prevent debilitating hacks by criminals or state actors.

But the country’s 2.7 million miles (4.3 million km) of oil, natural gas and hazardous liquid pipelines have only voluntary measures, which leaves security up to the individual operators, experts said.

“Simply encouraging pipelines to voluntarily adopt best practices is an inadequate response to the ever-increasing number and sophistication of malevolent cyber actors,” Richard Glick, the chairman of the Federal Energy Regulatory Commission (FERC), said.

Protections could include requirements for encryption, multifactor authentication, backup systems, personnel training and segmenting networks so access to the most sensitive elements can be restricted.

FERC’s authority to impose cyber standards on the electric grid came from a 2005 law but it does not extend to pipelines.

Colonial Pipeline, the largest U.S. oil products pipeline and source of nearly half the supply on the East Coast, has been shut since Friday after a ransomware attack the FBI attributed to DarkSide, a group cyber experts believe is based in Russia or Eastern Europe.

The outage has led to higher gasoline prices in the U.S. South and worries about wider shortages and potential price gouging ahead of the Memorial Day holiday.

Colonial did not immediately respond to a query about whether cybersecurity standards should be mandatory.

The American Petroleum Institute lobbying group said it was talking with the Transportation Security Administration (TSA), the Energy Department and others to understand the threat and mitigate risk.


Cyber oversight of pipelines falls to the TSA, an office of the Department of Homeland Security (DHS), which has provided voluntary security guidelines to pipeline companies.

The General Accountability Office, the congressional watchdog, said in a 2019 report that the TSA only had six full-time employees in its pipeline security branch through 2018, which limited the office’s reviews of cybersecurity practices.

The TSA said it has since expanded staff to 34 positions on pipeline and cybersecurity. It did not immediately respond to a request for comment on whether it supports mandatory protections.

When asked by reporters whether the Biden administration would put in place rules, DHS Secretary Alejandro Mayorkas said it was discussing administrative and legislative options to “raise the cyber hygiene across the country.”

President Joe Biden is hoping Congress will pass a $2.3 billion infrastructure package, and pipeline requirements could be put into that legislation. But experts said there was no quick fix.

“The hard part is who do you tell what to do and what do you tell them to do,” Christi Tezak, an analyst at ClearView Energy Partners, said.

U.S. Representatives Fred Upton, a Republican, and Bobby Rush, a Democrat, said on Wednesday they have reintroduced legislation requiring the Department of Energy to ensure the security of natural gas and hazardous liquid pipelines. Such legislation could get folded into a wider bill.

The power grid is regulated by FERC, and mostly organized into nonprofit regional organizations. That made it relatively easy for legislators to put forward the 2005 law that allows FERC to approve mandatory cyber measures.

A range of public and private companies own pipelines. They mostly operate independently and lack a robust federal regulator.

Their oversight falls under different laws depending on what they carry. Products include crude oil, fuels, water, hazardous liquids and – potentially – carbon dioxide for burial underground to control climate change. This diversity could make it harder for legislators to impose a unified requirement.

Tristan Abbey, a former aide to Republican Senator Lisa Murkowski who worked at the White House national security council under former President Donald Trump, said Congress is both the best and worst way to tackle the problem.

“Legislation may be necessary when jurisdiction is ambiguous and agencies lack resources,” said Abbey, now president of Comarus Analytics LLC.

But a bill should not be seen as a magic wand, he said.

“Standards may be part of the answer, but federal regulations need to mesh with state requirements without stifling innovation.”

U.S. senator asks firms about sales of hard disk drives to Huawei



A senior Republican U.S. senator on Tuesday asked the chief executives of Toshiba America Electronic Components, Seagate Technology, and Western Digital Corp if the companies are improperly supplying Huawei with foreign-produced hard disk drives.

Senator Roger Wicker, the ranking member of the Commerce Committee, said a 2020 U.S. Commerce Department regulation sought to “tighten Huawei’s ability to procure items that are the direct product of specified U.S. technology or software, such as hard disk drives.”

He said he was engaged “in a fact-finding process… about whether leading global suppliers of hard disk drives are complying” with the regulation.

Colonial Pipeline hackers stole data on Thursday



The hackers who caused Colonial Pipeline to shut down on Friday began their cyberattack against the top U.S. fuel pipeline operator a day earlier and stole a large amount of data, Bloomberg News reported citing people familiar with the matter.

The attackers are part of a cybercrime group called DarkSide and took nearly 100 gigabytes of data out of Colonial’s network in just two hours on Thursday, Bloomberg reported late Saturday, citing two people involved in the company’s investigation.

Colonial did not immediately reply to an email from Reuters seeking comment outside usual U.S. business hours.

Colonial Pipeline shut its entire network, the source of nearly half of the U.S. East Coast’s fuel supply, after a cyber attack that involved ransomware.
