We’re all used to swapping RAM in our desktops and laptops. What about a GPU, though? [dosdude1] teaches us that soldered-on RAM is merely a frontier to be conquered. Of course, there’s gotta be a good reason to undertake such an effort – in his case, he couldn’t find the specific type of Nvidia GT640 that could be flashed with an Apple BIOS to have his Xserve machine output the Apple boot screen properly. All he could find were 1GB versions, and the Apple BIOS could only be flashed onto a 2GB version. Getting 2GB worth of DDR chips on Aliexpress was way too tempting!
The video goes through the entire replacement process, to the point where you could repeat it yourself — as long as you have access to a preheater, which is a must for reworking relatively large PCBs, as well as a set of regular tools for replacing BGA chips. In the end, the card booted up, and, flashed with a new BIOS, successfully displayed the Apple bootup logo that would normally be missing without the special Apple VBIOS sauce. If you ever want to try such a repair, now you have one less excuse — and, with the GT640 being a relatively old card, you don’t even risk all that much!
Quantum computers could cause unprecedented disruption in both good and bad ways, from cracking the encryption that secures our data to solving some of chemistry’s most intractable puzzles. New research has given us more clarity about when that might happen.
Modern encryption schemes rely on fiendishly difficult math problems that would take even the largest supercomputers centuries to crack. But the unique capabilities of a quantum computer mean that at sufficient size and power these problems become simple, rendering today’s encryption useless.
That’s a big problem for cybersecurity, and it also poses a major challenge for cryptocurrencies, which use cryptographic keys to secure transactions. If someone could crack the underlying encryption scheme used by Bitcoin, for instance, they would be able to falsify these keys and alter transactions to steal coins or carry out other fraudulent activity.
Cybersecurity professionals are already using this tech to identify new types of malware and protect sensitive data for organizations. The beauty of implementing AI systems in a cybersecurity strategy is that they learn as they analyze more data, so they get better at their jobs with new experiences.
The business world is ever-changing, and customer behavior is evolving. Managing the radical transformation can be challenging, but it doesn’t have to be when you’ve got AI at your beck and call. Several SMEs and startups have leveraged AI to capture market share and establish their brand.
Soon, AI in business will no longer be a luxury — it will be a necessity. Companies that don’t keep pace with consumers’ expectations will fall short and lose market share. The only way to stay relevant is to adopt the trend.
North Korean-backed hacking group Lazarus has added the Windows Update client to its list of living-off-the-land binaries (LoLBins) and is now actively using it to execute malicious code on Windows systems.
The new malware deployment method was discovered by the Malwarebytes Threat Intelligence team while analyzing a January spearphishing campaign impersonating the American security and aerospace company Lockheed Martin.
After the victims open the malicious attachments and enable macro execution, an embedded macro drops a WindowsUpdateConf.lnk file in the startup folder and a DLL file (wuaueng.dll) in a hidden Windows/System32 folder.
*The past two years has seen a rapid shift of work to remote and hybrid offices. The statistics show that hackers welcomed that shift and took advantage of the vulnerabilities and gaps in security by businesses.
* Cyber perils are the biggest concern for companies globally in 2022, according to the Allianz Risk Barometer. The threat of ransomware attacks, data breaches or major IT outages worries companies even more than business and supply chain disruption, natural disasters or the COVID-19 pandemic, all of which have heavily affected firms in the past year.
Cyber incidents tops the Allianz Risk Barometer for only the second time in the survey’s history (44% of responses), Business interruption drops to a close second (42%) and Natural catastrophes ranks third (25%), up from sixth in 2021. Climate change climbs to its highest-ever ranking of sixth (17%, up from ninth), while Pandemic outbreak drops to fourth (22%).y affected firms in the past year. past two years has seen a rapid shift of work to remote and hybrid offices. The statistics show that hackers welcomed that shift and took advantage of the vulnerabilities and gaps in security by businesses.
A team of security researchers at Avanan is reporting that hackers are taking advantage of a Google Docs security vulnerability—one that takes advantage of a comment feature. They are claiming that they saw hackers using the vulnerability to target 500 inboxes of 30 Outlook users involving over 100 individual email accounts.
The team at Avanan claims that they found an earlier exploit in Google Docs last June—one that allowed hackers to send phishing links to users. Then, this past October, they discovered that hackers had found another way to send phishing links to unsuspecting users, using the comment feature. They further claim that the vulnerability was not fixed by Google and because of that they began seeing hackers taking advantage of the vulnerability last month.
The hacking approach is both simple and straightforward—a hacker creates a Google Docs document and adds comments to it that include an @ symbol followed by an email address. The symbol automatically alerts the system to send an email to the person designated in the email address—the email that is sent has phishing links in it, sending the user to a webpage that could lead to malicious code.
Athletes headed to the Beijing Olympic Winter Games are making final travel preparations, including keeping in line with China’s health measures on the “My 2022″ smartphone app. However, inadequate encryption measures within the app can leave Olympians, journalists and sports officials vulnerable to hackers, privacy breaches, and surveillance, according to a cybersecurity report by the Citizen Lab obtained exclusively by DW. Additionally, the IT forensic specialists found that the app includes a censorship keyword list. The findings come as international concern over digital safety at the Games mounts. Germany, Australia, UK and US have urged their athletes and National Olympic Committees to leave their personal phones and laptops behind and to travel with special devices over fears of digital espionage. The Dutch Olympic Committee outright banned its athletes from bringing personal phones and laptops due to surveillance concerns.
In the Olympic Playbook for athletes and team officials, the International Olympic Committee states that the “My 2022″ app is “in accordance with international standards and Chinese law.” But based on its findings, Citizen Lab concludes that the insecure transmission of personal information “may constitute a direct violation of China’s privacy laws.” This is because China’s data protection laws require that a person’s health and medical records held digitally be transmitted and stored in an encrypted manner. Citizen Lab’s findings also raise questions concerning two Western tech giants that carry the “My 2022″ app: Apple and Google. “Both Apple’s and Google’s policies forbid apps to transmit sensitive data without proper encryption, so Apple and Google will need to determine whether the app’s unresolved vulnerabilities warrant delisting,” Citizen Lab’s Knockel told DW. The Beijing Organizing Committee has stood by its app, however, saying it “passed the examination” of international mobile application markets such as Google, Apple and Samsung.“We have taken measures such as personal information encryption in the app to ensure privacy security,” the committee said Monday to Xinhua News Agency.
The Winter Games, which kicks off on February 4, marks the second Olympic Games during the COVID-19 pandemic. Just as at the Tokyo Summer Games, tracking athletes’ health is required. According to the official Playbook of the International Olympic Committee (IOC), athletes, coaches, reporters and sports officials, as well as thousands of local staff, are required to put their information into either the “My 2022″ smartphone app or website. The app, which was developed in China, is designed to monitor the health of all attendees and staff as well as trace possible COVID-19 infections. Passport data and flight information must be entered into the app. Sensitive medical information related to possible COVID-19 symptoms are also required, such as whether a person had a fever, fatigue, headaches, a dry cough, diarrhea or a sore throat. Those coming from abroad must start entering health data 14 days before arriving in the country. Many countries use a contact tracing app to help combat the pandemic. But “My 2022″ combines contact tracing with other services: It regulates access to events, acts as a visitor’s guide with information on sporting venues and tourist services, as well as providing chat functions (text and audio), news feeds and file transfers.
