Vulnerability in Physical Wallets Raises Alarm and Reinforces the Need for Diversification in Crypto

With the diversion of over $100 million due to a security flaw, economist Charles Mendlowicz points out that fractionating custody is the only real shield in the sector

The cryptocurrency market was taken by surprise by one of the most severe vulnerability episodes in its recent history. What has always been pointed out by experts as the ultimate safe haven for storing digital assets -- the so-called physical wallets or hardwallets -- has become the target of an attack. In fact, the attack diverted around $110 million. The flaw originated in the logic of generating private keys. Furthermore, it affected thousands of wallets from Coinkite Inc.'s Coldcard devices.

According to Charles Mendlowicz, partner at wealth management consultancy Ticker Wealth and founder of the channel Economista Sincero, the severity of the case lies in the breach of the sense of protection. People who lost their bitcoins were theoretically protected with physical wallets. Therefore, this type of breach compromises even long-term investors. "They keep funds stored without constant monitoring," explains the economist.

Attack Exposed Structural Flaw in Security Key Generation

Unlike historical collapses caused by fraud in centralized exchanges, such as the cases of Mt. Gox and FTX, the recent attack exposed a technical fragility. In this sense, this fragility was in the very code of creating the credentials of the devices.

The flaw in the randomness rule of the 12 keywords allowed attackers to replicate the logic based on the creation date of the wallets. Thus, they withdrew funds directly from users' custody. By discovering the rule of how this wallet used the 12 words, the hacker began to create in sequence and steal the tokens. Therefore, this generated frustration for those who paid dearly for equipment considered inviolable," comments Mendlowicz.

The release of firmware updates by the manufacturer does not reverse the losses of those who had their resources stolen. Therefore, for the economist, those who own devices under suspicion should take immediate measures. They should make a preventive transfer of their resources.

"If I had a wallet of this brand right now, I would calmly move my Bitcoins to some exchange. Or I would get another wallet for now," points out the Economista Sincero. Additionally, he also warns about the source of purchasing the equipment. Buying outside official channels exposes the investor to the risk of prior tampering of the hardware.

Diversification of Custody is an Essential Strategy

In light of the constant risk of technological failures, Mendlowicz emphasizes that depositing all digital assets in a single solution represents a strategic error.

The appropriate posture for capital preservation requires institutional and custody diversification of assets. "The safest way to hold crypto these days is by diversifying. What can harm the investor is leaving all their cryptos in one place. Fractionating capital among hardwallets, established exchanges, banks, and regulated ETFs is the only effective shield in the market," concludes Charles Mendlowicz.
