According to Chainalysis, the total cryptocurrency stolen from individual wallets and exchanges reached $2.17 billion during the same period. This represents a 35% increase compared to the same period last year. Moreover, around 23% of the stolen assets came from individual wallets, highlighting the growing security risks for personal crypto holdings.

Crypto Thefts in the First Half of 2025

During the first six months of 2025, cyberattacks on cryptocurrency exchanges resulted in significant losses. Financial Times reported on November 9, 2025, that the total stolen assets exceeded $2 billion. The largest single incident, the Bybit hack, attributed to North Korean-linked groups, involved approximately $1.5 billion in stolen funds. These figures underscore the need for investors to adopt stricter security measures.

Why Investors Are Moving to Their Own Wallets

Centralized exchange custody solutions carry significant risks due to high-volume attacks. Hardware wallets provide protection by keeping private keys under user control, reducing vulnerability to hacks.

Additionally, self-custody solutions help minimize the risks associated with centralized exchanges and increase the overall security of crypto assets.

The Importance of Self-Custody Solutions

Hardware wallets and cold storage systems are critical for investors. By storing crypto assets offline, these solutions prevent potential hacking attempts. Experts predict that self-custody practices will become increasingly popular in the future.

Hardware wallet manufacturers report a significant increase in sales due to growing security concerns. Ledger, Trezor, and Tangem stand out in the market. Analysts note that both individual and institutional users are turning toward secure storage solutions.

Benefits of Self-Custody:

• Full control over assets

• High protection against cyberattacks

• Reduced centralized exchange risk

• Long-term investment security

Seed Phrase Trap: Social Engineering at Its Worst

Ed Suman, a 67-year-old former fabricator for top artists like Jeff Koons, spent decades in the art world before shifting his focus to cryptocurrency investing. Over time, he amassed 17.5 Bitcoin (BTC) and 225 Ethereum (ETH) — the core of his retirement portfolio — stored safely in a Trezor Model One hardware wallet.

But in March, he received a text message that appeared to be from Coinbase, alerting him to suspicious account activity. He replied, and shortly afterward, a man calling himself “Brett Miller from Coinbase security” called him.

The caller seemed legitimate, even referencing Suman’s use of a hardware wallet. Over the phone, he walked Suman through a supposed “security procedure,” which required him to enter his seed phrase into a site that perfectly mimicked Coinbase’s interface.

A second scam call came nine days later. After following the same process again, all of Suman’s crypto was gone.

Real Data Breach at Coinbase Raises Alarms

Coincidentally or not, Coinbase recently disclosed a data breach where attackers bribed Indian customer support contractors to access private user data — including names, account balances, and transaction histories.

Roughly 1% of monthly users were affected, including Sequoia Capital’s managing partner Roelof Botha. While no funds were confirmed stolen from him, the incident highlights growing concerns over third-party vulnerabilities.

Coinbase has since fired the compromised contractors and is planning to compensate affected users with a budget between $180 million and $400 million.

Hardware Wallets Are Not Foolproof

Suman’s tragic loss is a painful reminder: Seed phrases should never be entered into any website, regardless of how authentic it looks. The biggest threat in crypto isn’t always technology — it’s human manipulation.

One message. That’s all it takes for hackers to drain your entire wallet. A signed offchain message is now powerful enough to hand over control of your funds — no onchain transaction required.

EIP-7702: The Risky New Delegation Mechanism

Activated on May 7, 2025, Pectra’s centerpiece EIP-7702 introduces a transaction type called SetCode, which allows users to delegate control of their wallets via a simple signature.

Arda Usman, a Solidity smart contract auditor, confirmed: “An attacker can use this offchain signature to install malicious code into an externally owned account (EOA) and move ETH or tokens — without the user ever signing a transaction.”

This feature effectively transforms user wallets into smart contracts, opening the door to silent yet devastating attacks.

A Stealth Threat Via Innocent-Looking Messages

Yehor Rudytsia, an onchain researcher at Hacken, emphasized that this transaction type allows arbitrary code to be installed in wallets. Previously, such a change required an actual transaction; now, only a signature is enough.

This shift means phishing attempts, fake DApps, or Discord scams can now result in complete wallet takeovers. “We believe this will become the most common attack vector following the Pectra upgrade,” Rudytsia warned.

Wallet applications that fail to correctly interpret transaction type 0x04 are especially vulnerable.

Hardware Wallets Are Not Immune Anymore

The once-clear distinction between hot and cold wallets is fading. Rudytsia highlighted that hardware wallets are now just as vulnerable if users unknowingly sign malicious messages: “Once signed, all funds can be gone in a moment.”

To stay safe, users should:

• Never sign messages they do not fully understand.
• Look out for delegation requests, especially those involving nonce values.
• Be aware that some delegation signatures can be replayed on any Ethereum-compatible chain.

While multisig wallets offer more robust protection, single-key wallets — including hardware ones — must adopt new safeguards to prevent exploitation.

Differences Between Exchange Platforms and Cold Wallets

The methods of storing your crypto assets are broadly divided into two. On exchange platforms, your assets are held on exchanges. You do not have full control over these assets. In cold wallets, your private keys are completely under your control and stored offline. Ledger Flex is one of the secure solutions among cold wallets.

What’s in the Ledger Flex Box?

When you open the box of the product, Ledger Flex device, Recovery Sheet where you can save your private keywords, Type-C to Type-C connection cable and user manuals welcome you.

How to Set Up Ledger Flex

To manage and set up your Ledger device, download the Ledger Live app on your computer or smartphone. In this guide, we’ll use a smartphone.

1. Open the Ledger Live app and click Get Started.
2. Select Set up your Ledger and choose Ledger Flex.
3. Turn on your phone’s Bluetooth and press the button on the right side of the Flex device to power it on.
4. After a short wait, your phone will detect the device and display it on the screen. Select it.
5. If the codes on your phone and Flex match, tap Yes, they match on the Flex screen.
6. Verify that the device’s software is genuine and up-to-date using your phone. Approve any necessary updates to complete the process.

At this stage, your device has been paired with your phone, and all required updates are complete. Now, let’s move on to the exciting part—setting up your device. Follow these steps:

1. Assign a name to your device using the Set name option, then confirm it by selecting Confirm name.
2. Create a PIN code between 4 and 8 characters to unlock your Flex device.
3. Choose Set up as a new Ledger for a fresh setup.
4. This next step is perhaps the most critical. Write down the 24-word recovery phrase shown on the screen in a secure location. Do not store it digitally, take photos of it, or divide it into parts. Ensure it is protected against theft, hacking, fire, and water damage. Your recovery phrase grants access to your assets. If it is lost or compromised, your assets could be at risk.
5. After recording the words, select them in the correct order on your Flex device to finalize the setup.

The scammers targeted users who had subscribed to Trezor’s newsletter, claiming that there would be an update to the blockchains of cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), and TRON (TRX). With this fake update announcement, they aimed to steal users’ assets and private keys.

The Trezor team responded quickly, disabling the malicious link in the email text and limiting the threat’s reach. The Trezor company warned users to immediately delete any emails containing harmful links, and reminded them that all funds are safe and that users should not share their recovery words or security keys with anyone.

The company has recently been in the news after a cyber attack resulted in the theft of customer information by hackers. The company is increasing security measures and urging its users to be more careful about such fraudulent attempts. Trezor users who want to store their cryptocurrencies securely are advised to always be on the lookout for suspicious emails and to verify official update announcements.

Since Ledger started, many other companies have also started making similar wallets. But the hardware wallet is still very well-known for making secure hardware wallets. The name “Ledger” comes from the technology behind cryptocurrencies, called blockchain.

What Is A Crypto Ledger?

Crypto Ledger is like a big public record book that keeps track of all the transactions made with cryptocurrencies. When people use cryptocurrencies like Bitcoin, their transactions get recorded in this ledger. The ledger shows when the transaction happened, how much was sent, the addresses of the sender and receiver, and how many confirmations the transaction has received from the network.

A new blockchain, which is the technology behind cryptocurrencies, starts with a special “genesis block.” This block is made to begin the chain because no transactions have happened yet. After that, transactions are grouped into blocks and each new block is added to the previous one, forming a chain. This chain is the blockchain, which is a public ledger of transactions.

The wallet is a leader in making hardware wallets for cryptocurrencies. They released the first wallet of this kind to the public in 2014.

Why Should You Get a Ledger Wallet?

1. Offline Storage: With the wallet, you can store your coins offline in what’s called “cold storage.” This means that your private keys, which are like secret codes that give you access to your crypto, are not connected to the internet. This makes it impossible for hackers to steal them. Although you may need to connect your hardware wallet to the internet when you want to send transactions, when it’s not connected, it stays completely offline and safe.
2. Control of Your Keys: When you use a Ledger Wallet, you have full control over your private keys. This means you don’t have to rely on a third party like an exchange to keep your keys safe. If an exchange gets hacked and there’s no insurance to cover your losses, you could end up losing your crypto. That’s why many people who hold a significant amount of cryptocurrency prefer to invest in a hardware wallet like the ones made by Ledger.
