Microsoft Is Finally Killing RC4

After twenty-six years, Microsoft is finally upgrading the last remaining instance of the encryption algorithm RC4 in Windows.

of the most visible holdouts in supporting RC4 has been Microsoft. Eventually, Microsoft upgraded Active Directory to support the much more secure AES encryption standard. But by default, Windows servers have continued to respond to RC4-based authentication requests and return an RC4-based response. The RC4 fallback has been a favorite weakness hackers have exploited to compromise enterprise networks. Use of RC4 played a key role in last year’s breach of health giant Ascension. The breach caused life-threatening disruptions at 140 hospitals and put...

Hyperliquid price reclaims $25 as whales look to buy more HYPE

Hyperliquid price gained to above $25 as buyers piled into the HYPE token. Lookonchain shared details of two whales adding to their Hyperliquid positions. Lookonchain noted that the large investors had deposited $5 million in USDC into Hyperliquid to purchase more HYPE tokens.

The advance followed a large whale transaction earlier in the session, alongside on-chain data indicating continued accumulation...

XRP price struggles near $2.00 hurdle despite ETFs streak

Ripple token XRP’s price continues to face significant resistance. Bulls are constrained around the psychologically important $2.00 level. The token could spike above as the price is near $1.92.

XRP is struggling at this key level despite a remarkable streak of positive inflows into US-listed spot XRP exchange-traded funds (ETFs).

The pullback from its mid-year highs amid broader market volatility threatens the upside buoyed by institutional enthusiasm.

Spot price performances of top altcoins highlight this dynamic, but could Bitcoin’s bounce to $89,000 help XRP bulls?

XRP has encountered persistent challenges in reclaiming and sustaining levels above $2.00 following a sharp correction...

Casio A-11 — крошечный ноутбук, который работал от двух батареек…

Я всегда считал японские гаджеты из 90-х маленькими шедеврами инженерной мысли. При разборке и детальном рассмотрении, я часто поражался продуманной схемотехнике и технической продвинутости устройств тех лет, и миниатюрный ноутбук Casio Cassiopeia A-11 не стал исключением. Подумайте сами: портативный компьютер, схожий по производительности с 5-летним домашним ПК, мог работать всего от двух батареек и при этом предоставлял практически весь функционал полноценного десктопа. Интересно, что за диковинный гаджет японцы выпустили в 1997? Тогда жду вас под катом!
