Attack on Ledger crypto wallet leads to huge money thefts

Crypto giant Ledger spent December 14 warning users not to interact with web3 decentralized apps amid concerns over a supply chain attack.

The attack on the ‘Ledger dApp Connect Kit' library was found to be pushing a JavaScript wallet drainer, the company found.

Ledger has since confirmed that it was the victim of a phishing attack and that the error has been rectified, leaving users free to continue using Ledger Connect Kit

Crypto attack could have been avoided

Ledger confirmed at 4:49pm CET via a post on X that a former employee had fallen victim to a phishing attack which compromised their NPMJS account. The attacker used the compromised account to publish a malicious version of the Ledger Connect Kit, which used a rogue WalletConnect project to reroute funds to the hacker’s wallet.

Crypto researcher ZachXBT posted to X that over $610,000 had been stolen during the attack.

Ledger said that the malicious file, which affected versions 1.1.5, 1.1.6, and 1.1.7, was live for around five hours, but that the fund draining took place in a shorter period of around two hours. A fix was issued within 40 minutes of Ledger becoming aware, and the company has since confirmed that Ledger Connect Kit 1.1.8 is now fully propagated, and that users can continue as normal.

Ledger has also reported the attacker’s wallet address and frozen their USDT together with Tether.

Ledger CEO Pascal Gauthier has also responded to the incident, stating that the “unfortunate isolated incident” serves as a “reminder that security is not static” and that Ledger, and any other company, should continuously improve their security.

Gauthier added: “Ledger will support affected users in helping to find this bad actor, bring them to justice, track the funds, and work with law enforcement to help recover stolen assets from the hacker.”

Windows Copilot leak suggests deeper assimilation with Windows 11 features

Key Windows 11 features may soon be customizable as Microsoft further integrates its Windows Copilot AI assistant into the operating system. This tidbit comes from tech news site Windows Latest , which claims to have discovered new .json (JavaScript Object Notation) files within recent preview builds of Windows 11. These files apparently hint at future upgrades for the desktop AI assistant. For example, a “TaskManagerService-ai-plugin.json” was found which is supposedly a “plugin for Task Manager integration”. If this ever comes out, it could give users the ability to “monitor or close running apps using” Copilot. In total, six are currently tested and they affect various aspects of Windows 11. Next, there is an “AccessbilityTools-ai-plugin.json” that gives Copilot a way to “control accessibility [tools]. This would make it "easier for those with [a] disability to navigate through the system.” Third is “ai-plugin-WindowsSettings.json” for controlling important Windows 11 set...

Samsung's ViewFinity S9 may be the monitor creatives have been searching for

Originally revealed during CES 2023 , Samsung has finally launched its ViewFinity S9 5K monitor after nine long months of waiting.  According to the announcement, the ViewFinity S9 is the company’s first-ever 5K resolution (5,120 x 2880 pixels) IPS display aimed primarily at creatives. IPS stands for in-plane switching , a form of LED tech offering some of the best color output and viewing angles on the market. This quality is highlighted by the fact that the 27-inch screen supports 99 percent of the DCI-P3 color gamut plus delivers 600 nits of brightness.  Altogether, these deliver great picture quality made vibrant by saturated colors and dark shadows. The cherry on top for the ViewFinity S9 is a Matte Display coating to “drastically [reduce] light reflections.”  As a direct rival to the Apple Studio Display , the monitor is an alternative for creative professionals looking for options. It appears Samsung has done its homework as the ViewFinity S9 addresses some of...
