Coldcard Bitcoin Wallet Hack Grows to $75 Million as Firmware Flaw Drains Over 2,600 Wallet Addresses
Bitcoin held broadly steady above $64,000 this weekend even as security researchers revealed the scale of a major hardware wallet exploit continued to grow, with the total amount stolen from Coldcard wallet users climbing to roughly $75.1 million as investigators traced additional theft transactions tied to the same underlying firmware flaw.
The attack began late Thursday, July 30, with an initial 25-minute sweep that drained approximately 594 bitcoin, worth about $38 million at the time, from around 500 single-signature wallets secured by Coldcard hardware devices. Galaxy Research, a blockchain analytics firm, later identified a second, larger wave of theft transactions tied to the same attacker, ultimately tracking a combined total of 1,158.66 bitcoin, worth roughly $75.1 million, taken from 2,673 separate wallet addresses across two related sweeps.
The vulnerability responsible for the theft traces back to a firmware integration error introduced in Coldcard firmware version 4.0.0 in March 2021, according to security analysis published by Block, the fintech firm founded by Jack Dorsey. The flaw caused affected devices to bypass their dedicated hardware random number generator, the component specifically designed to ensure a wallet’s recovery seed cannot be predicted or reproduced by anyone other than the device’s owner, and fall back instead to a less secure, software-based method of generating that seed. According to Block’s analysis, the resulting seeds carried roughly 72 bits of entropy rather than the 128 bits normally expected, a weakness significant enough that an attacker with knowledge of certain non-secret device information could reconstruct candidate seed values and check them against public blockchain records to identify wallets holding funds.
Bitcoin Core developer instagibbs independently reproduced the underlying vulnerability using a fresh Mk3 device, confirming the affected code path described in Block’s research. Security researcher James O’Beirne warned that any user holding a single-key Coldcard Mk3 wallet generated between 2021 and 2023 without additional protections such as a passphrase, physical dice rolls or a multisignature setup should treat their funds as being at immediate risk.
Coinkite, the Canadian company that manufactures Coldcard hardware wallets, confirmed the vulnerability in a public statement and urged affected customers to move their funds to newly generated wallets as a precaution. The company said the issue specifically affects seeds generated on Mk3 devices running firmware version 4.0.1 or later, and separately disclosed that seeds generated on Mk4 and Mk5 devices before firmware version 5.6.0, and on Q devices before version 1.5.0Q, also carried reduced entropy compared to what the devices were designed to provide, though Coinkite said those device generations appeared unaffected by the actual theft. Coinkite has since released patched firmware addressing the underlying flaw, though the company and outside security researchers have stressed that a firmware update alone cannot fix a seed that was already generated under the vulnerable code, since the compromised randomness was baked into the wallet’s recovery phrase at the moment of creation. Anyone affected has been advised that generating an entirely new seed on updated firmware is the only reliable remedy.
Every wallet identified in the theft was a single-signature wallet holding more than 0.15 bitcoin, and many of the affected wallets had remained dormant for years before the attack. The creation dates of the compromised wallets spanned from 2021 to 2026, closely matching the period during which the flawed firmware had been publicly available as open-source code, a detail security researchers said indicates the attacker specifically targeted wallets based on when they were created rather than through any conventional hacking method such as phishing or malware.
Despite the scale of the theft, roughly $75 million and counting, Bitcoin’s overall market price showed little sustained reaction. The cryptocurrency closed out July 2026 up roughly 7% for the month, its strongest monthly performance since the current market recovery cycle began, and remained range-bound near $64,000 to $65,000 in the days following the exploit’s disclosure. Analysts have pointed to that resilience as a sign of continued underlying market confidence, even as the incident has drawn comparisons to the 2023 “Milk Sad” vulnerability, another widely publicized case in which weak random number generation compromised cryptocurrency wallet security.
Of the funds swept from the initial wave of theft, approximately 562 bitcoin was consolidated into a single address shortly after the attack and had not moved as of the most recent reporting, according to Block’s analysis, leaving open the possibility that authorities or blockchain investigators could eventually trace or freeze the stolen funds if the attacker attempts to move or cash out the consolidated holdings.
Bitcoin now enters August, historically the cryptocurrency’s weakest calendar month over each of the past four years, with the Coldcard incident adding a fresh layer of uncertainty to broader market sentiment already shaped by expectations around Federal Reserve interest rate policy and other macroeconomic factors heading into the fall.

RBI special windows seen big enough to bring in $100B
“If the current pace of FCNR(B) inflows, as reflected in the central bank data, continues, we may well see three-digit US dollar billion mobilisation, significantly exceeding the initial estimates of $50-60 billion,” said VRC Reddy, head of treasury, Karur Vysya Bank. “The momentum so far has been a pleasant surprise.”
The Reserve Bank of India (RBI) Saturday said the special programmes between them had mobilised $40.81 billion in foreign exchange inflows up to July 31. Of this, FCNR(B) deposits accounted for $36.72 billion, despite the current programme having been operational only since June 8. The strong response has prompted economists to raise their estimates of the eventual mobilisation under the scheme.
“The cumulative inflows across FCNR(B), ECB and OFCB could reach $90 billion or even higher. Collections so far have been much stronger than expected,” said Gaura Sengupta, chief economist, IDFC First Bank.

She has consequently revised FY27 balance of payments surplus forecasts to $40 billion from $25 billion earlier.
The dedicated facilities, announced by the RBI on June 5 and operationalised on June 8, provide concessional foreign exchange swaps to banks to encourage capital inflows, support the balance of payments, cushion the rupee and contain imported inflation. The FCNR(B) window remains open until September 30, while the ECB and OFCB windows will remain available until December 31.
Robust Flows
“We continue to see up to $75 billion being raised under these concessional schemes, helping fund the current account gap, with a possible balance of payments surplus of nearly $35 billion in FY27,” said Madhavi Arora, chief economist at Emkay Global Financial Services.
Madan Sabnavis, chief economist, Bank of Baroda, estimates the overall mobilisation around $70 billion. “We believe around $70 billion can come through the total window, with $50-60 billion from FCNR(B) alone and another $10 billion from ECB and OFCB, though those flows are likely to pick up only after September,” he said.

AI may hurt IT today, but it could create the sector’s next growth engine: Baroda BNP Paribas MF
The fund house believes the recent correction in IT stocks reflects concerns over tariffs, AI-led disruption and weak near-term earnings guidance, but says the long-term opportunity lies in the industry’s transition from pilot AI projects to large-scale enterprise deployments. Korde sees emerging demand for data engineering, cybersecurity, cloud integration, specialised semiconductor infrastructure and AI-enabled hardware as potential growth drivers, even if traditional revenue streams come under pressure.
“While the existing revenue pools may get impacted, every disruption provides an opportunity as well, as has been witnessed in the past,” he said in an interview with ETMarkets.
Edited excerpts from a chat:
The government’s policy thrust is firmly behind manufacturing, yet you are more bullish on services. What is the market underestimating about the services opportunity?
While there has been a visible thrust on the manufacturing sector through various measures such as introduction of Production Linked Incentives (PLI) and promoting Make in India, it is also quite noticeable that the service sector has not been ignored. Various policies such as national Tourism Policy 2015, National Education Policy 2016, National Health Policy 2017, and initiatives like the National Mission on Pilgrimage Rejuvenation and Spiritual, Heritage Augmentation Drive (PRASAD) to name just a few, have helped drive growth in the services sector as well. Interestingly, The Gross Value Added by the Services sector has averaged 7.1%* year on year growth in the past 20 years, higher than both Industry and Agriculture average growth rate.
Which segments within services—financials, IT, healthcare, telecom, travel or digital businesses—offer the strongest earnings visibility over the next three to five years?The services sector offers multiple sectoral opportunities to invest in: Financial Services, Information Technology, Consumer Services, Power, Healthcare, Telecommunication, Oil & Gas, Telecommunication, Services, and Media & Publication. A lot of companies within these sectors have been growing at a fair clip in the past 5 years. We project good growth visibility in Financial Services (on low credit penetration and financialization of savings), Healthcare (aging demographics, expanding middle class, lifestyle diseases and wellness focus, and potential to see increase in medical value tourism), and Consumer Services (rapid digital acceleration boosting growth in e-commerce and quick commerce driving volumes across audience).
Indian IT services face uncertainty from AI-led disruption. Do you see AI as a threat to existing revenue pools or as the sector’s next growth driver?
The IT Sector has corrected by 23% over the last 1 year led by concerns around uncertainty led by tariffs and AI dominance. Even the growth guidance for FY27 remains weak, though the sector is a beneficiary of the weaker local currency. So, while the impact on stock prices has been immediate, there hasn’t been adequate clarity on how the opportunities might manifest. However, there can be potential prospects as the move from pilot AI projects to scaled enterprise deployments occur, which may be in the form of massive data engineering, new cybersecurity frameworks, or cloud integration & architectures and specialized semiconductors (GPUs, NPUs, TPUs), edge-AI devices, and data center infrastructure on the hardware side. To sum up, while the existing revenue pools may get impacted, every disruption provides an opportunity as well, as has been witnessed in the past.
Financial services represent a significant part of the listed services universe. Where do you currently see the best risk-reward—banks, NBFCs, insurers, asset managers or capital-market businesses?
Within the Financial Services space, we have a preference for Mid cap banks, NBFCs and platform companies in that order.
From a broader market perspective, do you expect returns over the next year to be driven by earnings growth, valuation expansion or sector rotation?
Generally, the markets do well when there is confidence in the earnings growth trajectory. IMF projects India’s GDP growth at ~6.4% for FY27* and identifies India as the fastest-growing major global economy, bolstered by resilient domestic consumption, robust services activity, and reduced external tariffs. This is higher than their projected growth rate of 3.9% for emerging markets and developing economies and 3.1% for the World. In this scenario, earnings growth, especially if the war scenario tapers off, can be a good growth driver for the markets. Of course, if this war extends further, or in case of additional hostilities elsewhere, corporate earnings are vulnerable to the tune of 300-500bps, in which case instead of earnings growth, sector rotation can be the driver.
Midcap valuations remain elevated despite uneven earnings delivery. Where do you still find a favorable risk-reward, and which segments appear priced for perfection?
While Midcap valuations may appear expensive in isolation, the current valuation is at a 6% discount to the past 8 year average PE multiple of the index. Similarly, even the large cap Nifty 100 index is trading at a lower valuation (by~8%) to its past 8 year average. At the same time, the small cap index is trading at a premium to its historical valuation. Hence risk reward broadly appears to be favourable in valuation terms for both mid cap and large cap segments.
Which sectors currently offer the strongest overlap between the midcap and value frameworks, and will return over the next three years be driven primarily by earnings growth, valuation rerating or successful corporate turnarounds?
To answer the latter part of the question, as mentioned earlier, earnings growth for India should be a key driver for returns. Successful corporate turnarounds are unique and company specific events, so they cannot be classified as a category driver, while valuation rerating is often derived as a function or outcome of improved earnings growth trajectory.
In the context of Indian markets, the mid cap framework is largely growth oriented, but following the Growth at Reasonable Prices (GARP) philosophy helps in identifying some themes closer to the value philosophy. We see Financial Services and IT offering good overlap between these frameworks due to stock correction, discounted valuation as compared to historical averages, overall good management quality, and healthy cash flow generation.
If you must start an SIP of Rs 10,000 as an investor with moderate risk appetite at this stage, how would it be spread out across various fund categories? Consider a long-term horizon of 10 years.
While it is difficult to be generic when individual investor risk return profile and tenure are different, and a planner with a holistic view of the client can be a better judge on these aspects, we believe a broad core portfolio from a longer term perspective would appear as spread 20% in hybrid (BAF), 20% each in the large / mid / small categories and the balance 20% in a thematic (value / services / consumption).

India, Canada aim to conclude CEPA trade pact by end-2026: MEA
In a written reply in the Rajya Sabha, minister of state for external affairs Kirti Vardhan Singh said on Friday that three rounds of CEPA negotiations have been held so far, with the latest round taking place in Ottawa from July 6-10. “Progress has been made across multiple negotiating tracks, with both sides working towards concluding the process by late 2026,” he said. PM Narendra Modi plans to visit Canada later this year to give further momentum to bilateral ties, which have improved under the current dispensation in Ottawa. The MEA said the proposed India-Canada CEPA aims to establish a free trade area by eliminating or reducing tariffs and other trade restrictions. The agreement is also intended to progressively liberalise trade in goods and services, promote a more transparent, predictable and facilitative trade and investment regime, and strengthen economic cooperation and people-to-people ties.
Canada represents a market of 41.65 million people, as of 2025, and $2.34 trillion in terms of GDP in terms of purchasing power parity.
The India-Canada CEPA holds significant potential to unlock and expand bilateral trade, which stood at $8.66 billion in 2024-25, comprising exports worth $4.22 billion from India and imports of $4.44 billion, according to an official.

Govt’s urban reset: Centre divides ministry of Housing and Urban Affairs into two specialised verticals
The administrative revamp follows the government’s decision last Thursday to split the ministry into two specialised verticals: Department of Capital Development (Rajdhani Vikas Vibhag) and the Department of Urban Development (Shehari Vikas Vibhag). The division is designed to enable dedicated focus on distinct aspects of urban planning while streamlining service delivery, execution, and policy interventions.
The administrative reshuffle moved at breakneck speed. Within 24 hours of the Gazette notification, secretary Srinivas Katikithala (a 1989-batch IAS officer of Gujarat cadre) handed over charge of the newly-created department of capital development to D Thara, a 1995-batch IAS officer from the same cadre. Simultaneously, the Centre posted Satendra Singh (a 1995-batch Jharkhand cadre IAS officer) as secretary to lead the Department of Urban Development. The overhaul extends deep into the operational leadership of Centre’s core urban schemes.
Crucial personnel shifts include Kuldeep Narayan, who was directing the flagship housing scheme Pradhan Mantri Awas Yojana (Urban), moving to Niti Aayog. Roopa Mishra, who spearheaded the Swachh Bharat Mission (Urban), has also been reassigned. New directors are slated to assume charge within the next fortnight to ensure seamless administrative continuity. At the heart of this structural realignment is a targeted policy focus on the national capital. The Centre has set its sights on resolving Delhi’s long-standing, complex urban challenges through a bifurcated strategy. With a BJP government in power in Delhi, the ministry bifurcation will also help in better implementation of infrastructure projects, including the ambitious Central Vista project.
