On the first day of the 10th iteration of the consumer-focused Pwn2Own Toronto 2022 hacking competition, competitors successfully penetrated the Samsung Galaxy S22 smartphone twice.

The STAR Labs team executed their faulty input validation assault on their third attempt, becoming the first to effectively exploit a zero-day on a Samsung flagship mobile, earning them $50,000 and 5 Master of Pwn points.

The Samsung Galaxy S22 was the target of another contestant’s successful exploit, demonstrated by Chim, who also earned $25,000 (or 50% of the reward for the second round of targeting the same device) and 5 Master of Pwn points.

The competition’s organisers state, “The first winner on each objective will get the whole cash award and the equipment under test.

“All other winners will receive 50% of the prize package for the second and future rounds on each target, but they will still gain the full Master of Pwn points.”

The Galaxy S22 devices in both instances ran the most recent version of the Android operating system with all available updates installed, in accordance with the contest’s regulations.

On the competition’s opening day, competitors successfully demonstrated exploits that target zero-day flaws in printers and routers from a variety of manufacturers, including Canon, Mikrotik, NETGEAR, TP-Link, Lexmark, Synology, and HP.

ZDI awarded a total of $400,000 today for 26 original and effectively demonstrated zero-day vulnerabilities.

Four days were added to the contest.
Security researchers can hack mobile phones, home automation hubs, printers, wireless routers, network-attached storage, smart speakers, and other devices that are all current and set to their default configuration during the Pwn2Own Toronto 2022 hacking competition hosted by Trend Micro’s Zero Day Initiative (ZDI).

For breaking into the Google Pixel 6 and Apple iPhone 13 handsets, they can receive the largest payouts in the mobile phone category, with cash awards ranging up to $200,000.

The maximum reward for a single challenge is $250,000 for a complete exploit chain with kernel-level access. Hacking Google and Apple devices can additionally result in $50,000 bonuses if the exploits execute with kernel-level privilege.

The consumer-focused Pwn2Own Toronto competition has been extended to four days (December 6–12) after 26 teams and competitors signed up to exploit 66 targets in all categories.

The competitive contest’s full schedule is available here. Here is the whole agenda for the first day of Pwn2Own Toronto 2022 as well as the outcomes for each task.

The Samsung Galaxy S22 will once more be put to the test by hackers from vulnerability research company Interrupt Labs on the second day of the competition.

For this reason, a lot of people are beginning to use software to manage their internet business reputation. This is done to make sure they have all the information they require about a clinic, hospital, or other establishment before taking a person there. However, patients must use this software package in order for this to happen. to ensure that they are providing reviews and compliments for the technique they examined. All of these advantages and benefits come from using this monitoring software application for your clinical procedure or company.

It encourages the marketing of a facility or clinical practise.

The fact that it encourages the marketing of the medical practise or establishment is one of the most important reasons why using online reputation monitoring in the healthcare industry is a great idea. However, this will only help the company if you receive positive reviews, recommendations, and comments.

It promotes advertising and marketing because the software will make it much easier for people to find the practise online if they are looking for it. After that, they may choose if this is something they should consider employing or not. However, it will also include negative remarks and also evaluations.

letting your patients know how your practise is doing

When you employ physician internet reputation monitoring software, you can be sure that you are telling your clients the truth about your practise. enabling them to express exactly how they perceive the technique or clinic in their own words. And they believe that what they believe can change the approach to make it much better for the patients.

Because you aren’t the one waiting in the waiting room, this is a great concept. In addition, they might have access to information that you do not. Giving your people a voice in your strategy can be a smart idea because of this. When they create an online evaluation, they can accomplish this.

Make it easier for others to find you online.

Generally speaking, this benefit is the same as the marketing and advertising benefit. Due to the doctor’s online reputation monitoring software, specifically a Google search, people can find your approach online. making it simpler for new customers to find your approach.

However, they will also find this to be simpler if you receive a lot of negative feedback. This is why, if any of your current patients are leaving comments, you need to make sure they are all good. Regardless of whether there are techniques that can’t be found online, this can help or hurt your practise.

The only thing to keep in mind is that, under any circumstances, you should never comment negatively on someone. The only thing that can determine whether you’ll get new patients or not is what you do.

enabling you to improve the flaws in your approach.

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.
