Uptycs Threat Research Team has discovered malware that not only hijacks vulnerable *nix-based servers and uses them to mine cryptocurrency but actually modifies their CPU configurations in a bid to increase mining performance at the cost of performance in other applications.

Perpetrators use a Golang-based worm to exploit known vulnerabilities like CVE-2020–14882 (Oracle WebLogic) and CVE-2017–11610 (Supervisord) to gain access to Linux systems, reports The Record. Once they hijack a machine, they use model-specific registers (MSR) to disable the hardware prefetcher, a unit that fetches data and instructions from the memory into the L2 cache before they are needed.

Hackers have siphoned $611 million worth of cryptocurrencies from a blockchain-based financial network in what’s believed to be one of the largest heists targeting the digital asset industry, putting it ahead of breaches targeting exchanges Coincheck and Mt. Gox in recent years.

Poly Network, a China-based cross-chain decentralized finance (DeFi) platform for swapping tokens across multiple blockchains such as Bitcoin and Ethereum, on Tuesday disclosed unidentified actors had exploited a vulnerability in its system to plunder thousands of digital tokens such as Ether.

“The hacker exploited a vulnerability between contract calls,” Poly Network said.

The U.S. dollar remains the world’s de facto monetary reserve, but with China going full speed ahead with its digital yuan, that could be in jeopardy. Researchers are digging into regulated online money called Central Bank Digital Currencies, or CBDCs, and what that could look like in the U.S.

The SENS Research Foundation has apparently already raised four times its annual income thanks to the PulseChain Airdrop.

The PulseChain airdrop supporting aging research

Richard Heart, the founder of HEX, is about to launch a new cryptocurrency called PulseChain. As part of that launch, he has also arranged an airdrop to give away some of the new cryptocurrency in order to support the SENS Research Foundation (SRF).

Pulsechain has raised $25000, 000 for antiaging medical research after 5 days of a 14 day fundraiser. You must follow the SENS.org PulseChain instructions. Sacrifices to SENS.org during the sacrifice phase earn 25% less points compared to sacrifices at Pulse.info. SENS.org can also accept stocks and bank wires. Once the sacrifice phase is over, the total sacrifice points for each sacrificer’s address’s points (at the same metamask address) are totaled up across all the supported chains and the SENS.org report. This creates a list of sacrificers ranked by total points from largest to smallest.

SENS Research Foundation has been working to develop, promote, and ensure widespread access to therapies that cure and prevent the diseases and disabilities of aging by comprehensively repairing the damage that builds up in our bodies over time. SENS is redefining the way the world researches and treats age-related ill health, while inspiring the next generation of biomedical scientists. Aubrey dr Grey and SENS have been the leading proponents of repairing aging damage to reverse aging effects. They have been leading the research effort for aging damage repair for over 20 years.

The Crypto world has been very supportive of SENS and antiaging research. In 2018, SENS received a $2.4 million Ethereum donation from Vitalik Buterin, the co-founder of Ethereum and the co-founder of Bitcoin Magazine.

Following a second exploit in 9 days, over 14 tokens listed on the ChainSwap bridge have plunged 99%. The company insists: funds from individual wallets are safe.

ChainSwap, a cross-chain asset bridge and application smart chain, has become the latest victim of the increasingly worrying exploits happening in the DeFi ecosystem that has caused the sector to lose hundreds of millions of dollars since the start of the year.

What is ChainSwap?

As a hub for smart chains, the ChainSwap protocol acts as a defi bridge for projects and users to seamlessly move assets between different blockchains like Ethereum (ERC20), Binance Smart Chain (BSC), and Huobi’s ECO Chain.

WTF?! On Thursday the Security Service of Ukraine (SSU) reported that they had shut down a cryptomining operation in the city of Vinnytsia, seizing over 500 GPUs and 50 processors — and a bunch of Playstation 4s. Consoles built on 2013-era technology might not be great at mining, but they don’t need to be when you have 3800 of them.

Although the market for GPUs is starting to improve, and dedicated ASICs might be on the way to relieve demand, it seems that one group of enterprising cryptocurrency miners have turned to last-gen console hardware to get things done.

From the photos provided by the SSU, it looks like these consoles are of the PS4 Slim variety, the 2016 refresh of the original console from three years prior. Mostly obsolete for newer games, it’s not at all surprising that so many could be sourced en masse so easily.

The toilet could turn roughly a pound of solid human waste, the average amount a human poops in a day, into an impressive 50 liters of methane gas, according to Cho. That means it can generate half a kilowatt hour of electricity, enough to drive an electric car for three quarters of a mile.

And because its 2021 — a day and age in which nothing is safe from the world of cryptocurrencies — Cho came up with a virtual currency called Ggool, or “honey” in Korean. Every use of the toilet scores you 10 Ggool per day, which can be used to buy stuff on the university’s campus.

“I had only ever thought that feces are dirty, but now it is a treasure of great value to me,” a postgraduate student Heo Hui-jin who’s both earned and spent Ggool, told Reuters. “I even talk about feces during mealtimes to think about buying any book I want.”
