Samsung Galaxy S21 and Galaxy A8 2018 receive new updates with March 2021 security patches – XDA Developers

Published

 on


When it comes to pushing monthly security updates, Samsung as an Android OEM has been doing a terrific job over the last few months. The company’s update schedule has improved to the extent that it’s now pushing the latest Android security patches to some of its devices even before Google officially publishes the corresponding Android Security Bulletin. Look no further: The shortest month of the year isn’t over yet, but the Galaxy S10, Galaxy Note 10, Galaxy Fold, and the Galaxy Tab S7 have already received the March 2021 patches. Well, it doesn’t seem like Samsung is stopping anytime soon, as the Korean OEM has now started rolling out similar updates for the Galaxy S21 and the Galaxy A8 2018.

Tagged with the version number G99x0ZHU1AUB7, the update for the Galaxy S21 series is intended for the Qualcomm Snapdragon 888-powered China/Hong Kong variants. As reported by SamMobile, the size of the incremental update package is about 387MB. Apart from bumping the security patch level, the new firmware also brings overall performance improvements as well as camera improvements.

Similarly, the company has started rolling out the March 2021 Android security patches for the Galaxy A8 2018 (model number SM-A530F) in the form of software version A530FXXSICUC1. The update is currently available in the XSG region, which is the Korean OEM’s internal code for the United Arab emirates.

Interestingly, the new build increments the underlying bootloader version from “H” to “I”. As a consequence, end-users can’t perform a downgrade and revert back to an older build after installing this update on their Galaxy A8 units.

As always, the updates are rolling out in batches. You might have to wait a couple of days before the update notification pops up on your device. However, if you are no stranger to manual flashing, you can just skip the waiting queue and use one of our community-developed tools to download the appropriate firmware for your device variant right now from Samsung’s update server.

At the time of writing this article, Samsung’s Mobile Security portal has not been updated with the details of the March 2021 security bulletin.

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

Published

 on

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.

THIN STAFFING

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

Published

 on

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

Published

 on

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.
