Trezor said it received a credible report of a hardware implant in a Safe 5 bought from reseller CryptoBilis in August 2026, though it has not yet examined the device. The reported implant reads the wallet backup from the screen and sends it over a mobile network, similar to Ledger's case, and the details have not been verified by Trezor. Trezor urged anyone who bought its wallets from CryptoBilis since March 2026 to move funds to a new wallet with a new recovery phrase, and said no buyer has reported a loss of funds. Trezor removed CryptoBilis as a reseller on October 9 and has inspected 4 devices bought from it without finding evidence of tampering.

- Ledger Announces Atom Touchscreen Android Device
Ledger has unveiled Atom, an Android touchscreen device with a Secure Element running Ledger OS, which it calls a 'signer' rather than a hardware wallet. The device has a data-only eSIM, encrypted messaging, and a 'Secure Mode' for sensitive actions such as signing transactions and approving AI agent requests, with a display physically isolated from Android and a hardware switch that cuts power to the camera and microphone. Solana Mobile named Ledger its first hardware expansion partner, so the Seeker app and Solana dApp Store, which lists more than 1,500 dApps, will come preinstalled. Reservations are open, but no price or shipping date has been announced, and the launch comes as Ledger investigates tampered hardware wallets sold through a Southeast Asian reseller.
- Trezor warns CryptoBilis buyers to move funds over suspected implant
Trezor urged customers who bought its hardware wallets from former reseller CryptoBilis since March to move their funds, after a report of a suspected unauthorized circuit board in a Trezor Safe 5 bought on Tokopedia in August. According to the report, the device could capture screen information, including wallet recovery phrases, and transmit it over a cellular network. Trezor has not yet examined the device and has received no reports of losses, and described sales through the reseller as “very small” without providing figures. The company is reviewing its hardware protections, as seals and packaging are not sufficient on their own, and plans to reduce its reseller network, announced on October 13. Earlier, Ledger wallets sold through CryptoBilis were found to contain an implant, and security researcher Joe Grand had alerted Trezor in August about tampered wallets.
- Ledger Asks Resellers in Seven Asian Markets to Pull Devices After Suspected $86M Drain
Ledger has asked resellers and distributors in six Southeast Asian countries and Hong Kong to suspend sales and pull its hardware wallets from shelves while it investigates devices fitted with a hidden implant. The implant reads the 24-word recovery phrase during setup and sends it out over LTE, so anyone holding that phrase can move the wallet's funds. All confirmed losses involve devices sold through CryptoBilis, a regional reseller, and Ledger has not verified any drain linked to devices bought elsewhere, nor sees any indication its own systems were compromised. Onchain investigator Specter has traced more than $86 million in suspected thefts, a figure Ledger has not verified. MediaMarkt Saturn stopped selling Ledger devices after a German customer reported an implant, though no funds were lost, and rival Trezor will end reseller authorizations on January 1, 2027 as a precaution.
- Trezor reduces resellers as a ‘preventative step’ amid Ledger tampering reports
Hardware wallet maker Trezor said it will reduce its number of resellers as a “preventive step” following reports that malicious implants were found in competitor Ledger’s devices. Chief commercial officer Danny Sanders said certain resellers will be removed from the authorized list on January 1 and will stop receiving Trezor shipments from Tuesday. Trezor said there is “not a single piece of evidence” that its own devices have been compromised, while Ledger confirmed that at least one device sold by reseller CryptoBilis in Southeast Asia contained an unauthorized implant that captured recovery phrases. Researchers estimate losses of between $72 million and $86 million, though Ledger has not confirmed the total number of affected users or value lost. CryptoBilis suspended all hardware wallet sales, and the parent company of MediaMarkt removed all Ledger products from its stores and online platforms.
- Trezor Cuts Its Resellers After Ledger Finds Spy Implant in Crypto Wallets
Trezor will end its reseller authorizations on January 1, 2027 and stop shipping new stock to them, calling it a precaution after supply-chain incidents and saying there is no evidence its devices were compromised. The move follows Ledger's Donjon team finding that wallets sold by Southeast Asian reseller CryptoBilis carried a spy implant that captures recovery phrases from the screen and sends them over LTE. Ledger told anyone who bought from CryptoBilis in the past 90 days not to set up their device, while onchain investigator Specter traced more than $86 million in suspected thefts, a figure Ledger says it has not verified. Trezor says CryptoBilis was already off its seller list and that it has received no reports of tampered devices from that retailer. Separately, a ShipMonk data exposure in August affected Trezor customers, with the total put at 80,689 in September, though Trezor says its devices, private keys and wallet backups were not affected.
- UK crypto trader says almost $800,000 lost in knife attack as wrench attacks proliferate
A U.K. crypto trader said masked intruders held him at knifepoint, destroyed his phone and forced transfers of about $40,000 from a hot wallet and $720,000 from his Ledger wallet, nearly $800,000 in total. He shared a Solana wallet address on Solscan as evidence, but police had not confirmed the incident. Chainalysis estimates criminals stole over $30 million through violent “wrench attacks” in the first half of 2026, with home invasions making up 37% of cases, up from 14% a year earlier. France was a hotspot, with at least 30 incidents recorded by Chainalysis and 33 of 52 verified global attacks identified by Certik.

- After Eli Lilly’s Explosive Earnings Report, Is It Too Late to Buy the Stock?
Eli Lilly reported third-quarter revenue up 39% to more than $24 billion, driven mainly by its weight loss portfolio. Mounjaro sales rose 65% to over $10 billion and Zepbound climbed 49% to $5.3 billion, while 40% of new patients starting an oral obesity medicine chose Foundayo. Lilly holds 63% of the U.S. market, and the stock is trading at a record high above $1,300, at 42x forward earnings estimates versus more than 70x in 2024. The article argues the weight loss market still has room to expand, since only 3% to 10% of potential U.S. patients access weight loss care, and that late-stage candidates such as retatrutide add to the growth outlook.
- Nvidia (NVDA) CEO Jensen Huang Reportedly Targeted In Chinese Espionage Plot
Reports say Nvidia CEO Jensen Huang was targeted in an alleged Chinese espionage plot. The reported operation has prompted fresh questions from US lawmakers about potential security vulnerabilities in Nvidia's AI chip development. Regulators and legislators are weighing the incident against existing restrictions on Nvidia's advanced AI chip exports to China. The article argues the episode could reinforce Washington's view of Nvidia as critical AI infrastructure, while also potentially hardening support for stricter licensing and oversight of where its top-end platforms are deployed, which could cap part of the addressable market.
- Shopify Stock Is More Than 10% Below Its Record. Should You Buy Before Its Nov. 3 Report?
Shopify (SHOP) closed at a record $179.22 on Oct. 12 but now trades about 12% below that level, including a roughly 6% drop on Friday. The e-commerce software company reports third-quarter results before the market opens on Nov. 3, after management set guidance in August for revenue growth in the low thirties, gross profit growth in the mid-to-high 20s and a free cash flow margin in the high teens to low 20s. The author notes Shopify has met or beaten its guidance all year, with revenue growth of 34% in both the first and second quarters, though the third quarter faces a tougher comparison. Shares fell about 16% on May 5 even though first-quarter revenue growth beat the outlook, and rose about 17% after the August report, suggesting investors judge more than guidance beats. At roughly 86 times trailing free cash flow, the author argues the drop does not change much and prefers to wait for the report and see where shares settle afterward.
- 5 Best High Growth Stocks Outside Big Tech
Market growth is unusually concentrated in a few mega-cap tech stocks, with ten AI-related names making up over 40% of the S&P 500's market capitalization. The article argues non-tech growth stocks merit a look, but growth must be weighed against margins, debt, customer concentration and capital intensity. Analysts expect the "Magnificent Seven" to grow third-quarter earnings 20.3% year over year, versus 27.7% for the other 493 S&P 500 companies, suggesting earnings momentum is broadening. Netskope is cited as an example: revenue rose 29.2% to $220.5 million, yet trailing EBITDA stayed negative at $721 million. The list screens non-tech stocks with market caps above $20 billion and at least 25% five-year EPS growth.
- The 5 most interesting analyst questions from Alphabet's Q3 earnings call
The market reacted sharply negatively to Alphabet's third-quarter results, even though revenue of $127.6 billion was in line with the S&P analysts' estimate of $127.9 billion. Earnings per share were $2.12 against an expected $3.01, a 29.6% miss. Management credited AI-driven momentum across Search, Cloud and YouTube for the strong top-line growth, and operating margin rose to 31.8% from 30.5% a year earlier, though rising costs for infrastructure and AI investment weighed on profitability. In the Q&A, analysts asked about productivity gains from new AI models, scaling agentic products to a billion users, compute allocation between internal needs and Cloud customers, and how TPU system sales affect cash flow.
- Here's Why Janus Henderson is Bullish On Meta Platforms, Inc. (META)
Janus Henderson has released its Q3 2026 investor letter for the Global Sustainable Equity Fund, reporting a 1.86% return for the quarter, in line with its benchmark and ahead of the 0.38% return of the IA Global peer group. Performance reflected a sharp rotation within the AI trade: companies seen as vulnerable to AI disruption recovered, while businesses tied to AI infrastructure, power, cooling and electrification came under pressure, and the fund's lack of energy holdings also weighed on relative results. The managers highlighted rising electricity demand from data centres, the potential of renewable energy and battery investments for energy security and decarbonisation, and the risks a strong El Niño could pose to agriculture and inflation. The fund remains focused on companies with pricing power, resilient operations and long-term structural growth amid geopolitical uncertainty, elevated energy prices and higher interest rates. The letter also discusses Meta Platforms, Inc. (NASDAQ:META), a company that operates social media platforms and develops AI products, digital advertising solutions, and virtual and augmented reality technologies.
