2X PERFORMANCE, $300K SAVINGS: A CASE STUDY IN REWRITING A CRITICAL SERVICE IN RUST

A TikTok intern tackled a CPU-bound payment service written in Go by selectively rewriting the most intensive API endpoints in Rust. This surgical rewrite resulted in a 2x performance increase, lower latency, and reduced CPU and memory usage. Testing guaranteed correctness before the Rust implementation was deployed, handling double the traffic of the original Go service, which led to a projected annual cost saving of nearly $300,000 in cloud expenses.

OPERATION SKYCLOAK DEPLOYS TOR-ENABLED OPENSSH BACKDOOR TARGETING DEFENSE SECTORS

Operation SkyCloak uses phishing emails with military document lures to deploy sophisticated backdoors targeting defense sectors in Russia and Belarus, establishing persistent access through legitimate OpenSSH services and customized Tor hidden services with obfs4 traffic obfuscation. The malware performs environmental checks to evade sandboxes, creates scheduled tasks for persistence, and enables remote access to critical Windows services (RDP, SSH, and SMB) through anonymous Tor addresses using pre-installed cryptographic keys. Security professionals should monitor for unusual scheduled tasks named after legitimate applications, implement network monitoring for Tor traffic patterns, and enhance email security controls to detect phishing campaigns using military-themed lures targeting defense organizations.

CRYPTOS TUMBLE, NEARING OCTOBER CRASH LOWS

Bitcoin fell below $106,000 with altcoins declining harder, fully reversing the bounce from the October 10 crash. The selloff liquidated over $1 billion in leveraged positions across digital assets, while crypto stocks fell, led by Circle (-7%), Gemini (-6%), Coinbase (-4%), and Strategy (-3%). FundStrat's Tom Lee maintains his bullish year-end targets of $200,000 for bitcoin and $7,000 for ether, stating "fundamentals are leading prices in crypto, so eventually we consolidate and then we rally into year-end."

TESLA IS OBSESSED WITH MUSK'S PAY PACKAGE. MUSK IS OBSESSED WITH AI

Elon Musk spent most of his time at xAI after he left DOGE in May, even holding meetings for Tesla employees at xAI's offices. Musk has balanced his responsibilities between several fast-growing companies for years, but the potential of AI has led him to spend much more of his time at xAI. Tesla will soon announce preliminary results on a giant pay package designed to ensure that Musk focuses on Tesla for years to come. The package would increase his stake in Tesla over a decade from 15% to around 25% if he hits ambitious goals.

MEET PROJECT SUNCATCHER, GOOGLE'S PLAN TO PUT AI DATA CENTERS IN SPACE

The cost of electricity on Earth is a problem for large data centers. Google plans to put data centers in space in a dawn-dusk sun-synchronous low-earth orbit to ensure they get almost constant sunlight exposure. It will require solar panels that are up to eight times more efficient to get the job done. The project will only be successful if Google's TPUs can run for at least five years. Google plans to launch a pair of prototype satellites by early 2027.
