You become infected with RedLine malware through fake Windows 11 upgrade installers.

Users of Windows 10 have begun to get phoney Windows 11 upgrade installers, tricking them into downloading and running RedLine stealer software.

The attacks took place at the same time that Microsoft announced the broad deployment phase for Windows 11. As a result, the attackers were well-prepared for this move and waited for the ideal time to maximise the effectiveness of their operation.

As the most extensively used password, browser cookie, credit card, and cryptocurrency wallet information thief at the moment, RedLine stealer infections can have serious negative effects on the victims.

The initiative

The attackers exploited the “windows-upgraded.com” domain for the malware distribution portion of their campaign, according to HP experts who have detected this effort.

When a visitor selected the “Download Now” button on the website, a 1.5 MB ZIP archive with the name “Windows11InstallationAssistant.zip” was downloaded directly from a Discord CDN. The website looks to be an official Microsoft website.

Decompressing the file yields a folder with a size of 753MB and a remarkable compression ratio of 99.8%, which was made possible by the executable’s inclusion of padding.

An encoded parameter starts a PowerShell process when the victim runs the programme in the folder.

A.jpg file is then retrieved from a distant web server when a cmd.exe process with a 21-second timeout has finished running.

The DLL in this file is organised in reverse, maybe to avoid detection and analysis.

The first process then loads the DLL and swaps it out for the current thread context. That DLL is a RedLine stealer payload that uses a TCP connection to communicate with the command-and-control server to receive instructions on what malicious operations should be performed next on the recently compromised system.

Outlook
Nothing prevents the actors from registering a new domain and continuing their campaign even though the distribution site is currently unavailable. In fact, it’s quite likely that this is already taking place in nature.

Due to hardware compatibility issues, many Windows 10 customers are unable to download Windows 11 via the official distribution channels. Malware operators see this as a great opportunity to recruit new victims.

The strategies disclosed by HP are not surprising at this time, as threat actors are also use Windows’ legitimate update clients to execute malicious code on compromised Windows systems, as BleepingComputer discovered in January.

Remember that these risky websites are advertised through forum postings, posts on social media, and instant messages, so only rely on the official Windows upgrade system alerts.

NVIDIA resolves critical issues affecting Windows and Linux devices.

NVIDIA resolves critical issues affecting Windows and Linux devices.

NVIDIA has released security upgrades to fix ten more bugs impacting the NVIDIA Virtual GPU (vGPU) management software in addition to six security holes discovered in Windows and Linux GPU display drivers.

The flaws make Windows and Linux systems vulnerable to attacks that could cause a denial of service, privilege escalation, data manipulation, or information disclosure.

Because all of these security flaws need local user access, potential attackers must first get access to susceptible targets via a different attack method.

Patching of eleven high severity vulnerabilities
Attackers can simply escalate privileges to obtain permissions above those provided by the OS after successfully exploiting one of the vulnerabilities fixed today.

Denial-of-service attacks or gaining access to otherwise inaccessible information can also be used to temporarily disable workstations running vulnerable drivers or software.

With the exception of the security flaws identified as CVE-2021-1052, CVE-2021-1053, and CVE-2021-1056 affecting the Linux GPU Display Driver for Tesla GPUs, which will start receiving an updated driver version on January 18, 2021, NVIDIA has patched all impacted software products and platforms.

The flaws have CVSS V3 base ratings ranging from 5.3 to 8.4, and NVIDIA has classified 11 of them as high-risk.

The risk assessment “is based on an average of risk across a broad set of deployed systems and may not represent the true risk of your local installation,” according to NVIDIA’s security alert.

To accurately assess the risk these vulnerabilities represent to your particular system configuration, the business further suggests speaking with an IT or security specialist.

The January 2021 Security Bulletin is a complete list of security problems that NVIDIA patched this month.

Several driver updates are accessible from hardware vendors.
NVIDIA advises users to use the security updates offered on the NVIDIA Driver Downloads page to upgrade their GeForce, NVIDIA RTX, Quadro, NVS, and Tesla GPU display drivers, as well as Virtual GPU Manager and guest driver software.

According to the business, certain consumers who choose not to manually fix the weaknesses might also get security upgrades bundled with Windows GPU display driver 460.84, 457.49, and 452.66 versions from their computer hardware vendors.

Users of the NVIDIA vGPU enterprise software must sign into the NVIDIA Enterprise Application Hub in order to download updates from the NVIDIA Licensing Center.

Internet Explorer 11 support will no longer be offered by WordPress.

Internet Explorer 11 support will no longer be offered by WordPress.

WordPress, the most well-known and widely used blogging platform, is thinking about removing support for Internet Explorer 11 when its usage falls below 1%.

WordPress has discovered that the cumulative usage of IE 11 is less than 1% using the following three metrics:

according to StatCounter’s GlobalStats, 0.71%.
from W3 Counter, 1.2%
from WordPress.com, 0.46%
When WordPress stopped supporting Internet Explorer 8, 9, and 10 in 2017, these usage figures were comparable.

WordPress plans to discontinue support for Internet Explorer 11 in the future due to the low number of users and the significant expense of maintaining the browser.

“Regarding the present WordPress user experience, the majority of WordPress users ought to be aware by now that a flag was introduced to BrowseHappy around 13 months ago to not recommend IE. In connection with this, the entire IE11 experience is subpar and comes with a significant maintenance cost for developers “Last week, WordPress clarified in a blog post.

WordPress is requesting feedback from individuals and organisations that still use the browser by March 18th in order to formulate their strategies for ceasing support.

WordPress is not the only platform to stop supporting IE 11.

Microsoft Teams’ web app will no longer be supported by Internet Explorer, and Microsoft 365 would stop supporting it on August 17, 2021, according to a 2020 August Microsoft announcement.

Major Canadian banks experience a bizarre, hours-long outage

Major Canadian banks experience a bizarre, hours-long outage

Major Canadian banks fell unavailable for several hours, denying consumers access to e-transfers, online and mobile banking, and other services.

The Canadian Imperial Bank of Commerce, Scotiabank, Bank of Montreal, and Royal Bank of Canada (RBC) are among the institutions apparently affected by the outage (CIBC).

For many, online banking and e-Transfers are not working.
Yesterday, the main banks in Canada went offline, making it difficult for many people to access e-Transfers, online, and mobile banking services.

The number of reports of people experiencing problems accessing their online banking peaked on Wednesday between 5 and 6 p.m. Eastern time, while BleepingComputer is still receiving an influx of these reports today:

 

An RBC spokesman acknowledged that “we are currently having technical challenges with our online and mobile banking, as well as our phone services.”

“We have no ETA to offer at this time, but our specialists are looking into it and striving to fix it as soon as they can. We value your tolerance.”

Customers continued to report problems a few hours later, within 30 minutes of RBC declaring that all systems were operating normally:

Andrew Currie, an RBC client, stated that the disruption left him without “access to my money at the grocery store” and forced him to wait in line for the cash register for 30 minutes.

Customers of BMO also noticed that the bank’s “Global Money Transfer service” was unavailable “all day” and that transfers were being automatically denied without any apparent cause. Such customers were advised to contact customer care by a BMO representative.

Inconsistencies with their internet banking were not acknowledged by CIBC.

Customers were apparently locked out of the TD Bank mobile banking app, and customer support agents said they “haven’t been told of recent concerns with our online service through EasyWeb.”

According to a TD Bank representative speaking to BleepingComputer, the bank had no significant system issues or outages.

It’s unclear at this moment whether some people’s difficulties at the ATMs were caused by the outage. According to an RBC staffer, the customer experiencing ATM problems is using an old debit card:

Some transfers are subject to rules under the Emergencies Act.

Although the reason for the outage is unknown, its timing is very intriguing because it comes only a few days after Canadian Prime Minister Justin Trudeau used the Emergencies Act in the midst of ongoing “Freedom Convoy” rallies.

Deputy Prime Minister Chrystia Freeland detailed the new rules that payment service providers must follow in accordance with the recently implemented Emergencies Act on Monday during a press briefing on Parliament Hill.

Additionally, without a court ruling and without risking civil liability, the Emergencies Act gives banks the power to freeze the accounts of people and companies they believe to be connected to the illegal blockades.

However, as the Deputy PM notes, since banks are currently required to report to FINTRAC, it is still unclear how new legislation will cause a planned or unanticipated outage.
