On Wednesday, Terra developers took the significant step of pausing network operations following a severe reentrancy attack that resulted in the theft of over $4 million worth of various tokens from the blockchain. This emergency halt occurred at block height 11430400 as developers rushed to implement an emergency patch to address the critical vulnerability. The fix was successfully deployed at 04:19 UTC.

Validators, who play a crucial role in maintaining the integrity of the network, representing over 67% of the voting power on Terra, promptly upgraded their nodes to mitigate the risk of future exploits, as detailed in a post on social media platform X.

According to estimates from security firm Beosin, the breach involved the theft of approximately $3.5 million in USDC stablecoins, $500,000 in USDT stablecoins, 2.7 bitcoin (BTC), and over 60 million tokens of Astroport’s ASTRO. The attack has been attributed to a specific reentrancy vulnerability identified in the timeout callback of ibc-hooks, which was initially disclosed back in April of this year.

In the wake of the attack, the value of ASTRO plummeted by 56%, as reported by CoinGecko. Additionally, Terra’s luna classic (LUNC) tokens experienced a decline of 3.4% within the last 24 hours.

Reentrancy vulnerabilities are a well-known type of bug that can be exploited by malicious actors. They allow attackers to deceive a smart contract into executing repeated calls to a protocol, ultimately leading to the unauthorized theft of assets. This occurs when the initial call grants the smart contract address the ability to interact with a user’s wallet address, creating a window of opportunity for exploitation.

The National Transportation Safety Board (NTSB) released a preliminary report stating that a Tesla Semi electric truck in California required firefighters to use “50,000 gallons” (approximately 190,000 liters) of water to extinguish a roadside fire. Firefighting teams also deployed an aircraft to drop fire retardant on nearby areas as a precautionary measure to control the fire.

The accident occurred on August 19 at 3:13 AM local time on the I-80 highway east of Sacramento. The electric truck went off the road while navigating a curve, collided with a roadside boundary marker, and then struck a tree, coming to a stop. Fortunately, the driver was not injured in the accident; however, considering their health condition, they were taken to the hospital.

The Tesla Semi’s large 900 kWh battery caught fire upon impact, and toxic smoke began to spread during the fire. While the fire continued with temperatures reaching up to 538°C, firefighters worked intensively to cool the blaze with water. However, due to the fire’s effects, the vehicle continued to burn until late in the afternoon. Meanwhile, Tesla sent a technical expert to the scene regarding fire safety and high voltage hazards.

The highway reopened to traffic at 7:20 PM local time, 16 hours after the accident. The NTSB, as an organization that can only make recommendations and cannot enforce regulations, sent a team to the area for investigation purposes. This major accident raised several issues, including dangerously hot fires and toxic smoke, which will attract the attention of many international organizations.

The NTSB had previously stated in 2021 that fires in the batteries of electric vehicles pose serious risks to emergency response teams and that the guidelines provided by manufacturers for such fires are inadequate.

New Leaks About Samsung Galaxy S25 Ultra

Samsung is expected to introduce the Galaxy S25 Ultra along with the Galaxy S25 series at the beginning of 2024, likely in January. Although no official announcement has been made yet, leaks regarding the upcoming flagship continue to spread rapidly on the internet. Notable leak source IceUniverse shared several new visuals of the Galaxy S25 Ultra in a post on the X platform. These visuals reveal the design differences between the Galaxy S25 Ultra and the Galaxy S24 Ultra.

One of the notable features in the leaked images of the Galaxy S25 Ultra is the rounded corners of the phone. In contrast, this year’s Galaxy S24 Ultra has quite sharp corners, which has led to feedback from some users indicating discomfort while holding the device. Previous leaks have suggested that the Galaxy S25 Ultra may be somewhat larger.

A tweet shared by IceUniverse: Galaxy S25 Ultra Image

According to leaks, the Galaxy S25 Ultra is expected to be thinner and lighter compared to previous models. In August, rumors emerged that the upcoming Galaxy S25 Ultra would be lighter than its competitors, with a weight of under 221 grams.

Another image featured in IceUniverse’s post shows close-ups of the sides of both next year’s expected flagship phone and Samsung’s current flagship. In this image, the side of the Galaxy S25 Ultra appears flatter with rounded corners. While these changes may not create a major revolution, they will generally positively affect the feel of the phone in hand.

Looking at other rumors about the Samsung Galaxy S25 Ultra, it is expected that the company will offer top-tier screen and camera upgrades next year. Additionally, there is a strong expectation that the satellite connection feature will also be introduced alongside the Galaxy S25.

Apple officially launched iOS 18 yesterday, as promised. After a long beta testing phase, this update brings many exciting new features for iPhone users.

iOS 18 Officially Released: Innovations and Features

New Features in iOS 18

Advanced Customization Options on the Home Screen: With iOS 18, users can now arrange app icons freely without sticking to the traditional grid layout. Additionally, there’s an option to change the colors of the icons and adjust their darkness levels. In short, you are no longer bound to a boring layout. It raises questions why Apple waited until 2024 to offer this feature.
Revamped Control Center: The Control Center is completely redesigned in iOS 18. Users will be able to group controls more comfortably, and developers can easily add controls from their applications. Also, there’s an option to divide the Control Center into pages, allowing different controls on each page.
RCS Messaging Support: With iOS 18, Apple introduces Rich Communication Services (RCS) messaging support. Users can add various effects to their texts and react with new emojis for more colorful responses.
Updated Photos App: The Photos app is presented with a new opening page and a modern layout. Users can now browse photos by time, people, and many other criteria, reorder media files, and explore more with the “Collections” feature.
App Lock Feature: Users can now lock specific applications. For example, they can activate Face ID protection from the menu that appears when long-pressing an app icon. Thus, anyone wanting to open the app will have to pass the Face ID protection first.
Apple Intelligence: One of the important features of iOS 18 is Apple’s artificial intelligence kit, Apple Intelligence. However, to fully benefit from this feature, you’ll need to wait for the iOS 18.1 update. More information about Apple Intelligence can be found here.
