When Depth Becomes an Illusion: Polymarket Faces 'Order Attack' Stress Test

A sophisticated "order attack" is exploiting a critical vulnerability in Polymarket's hybrid off-chain matching/on-chain settlement system. For less than $0.10 in gas fees on Polygon, an attacker can initiate a trade and then, in the brief window before on-chain execution, drain their wallet via a high-gas transfer. This causes the initial trade to fail on-chain due to insufficient funds. However, Polymarket's off-chain system responds by forcibly removing all the legitimate market maker orders that were matched with the failed transaction. This attack has two primary profit methods. First, attackers clear the order book of competitors, create a liquidity vacuum, and then place their own orders with artificially wide spreads to monopolize trading. Second, they "hunt" automated trading bots: after a trade is matched off-chain, a bot hedges its new position, but the attacker then forces the original trade to fail on-chain. This leaves the bot with an unhedged, risky position, which the attacker exploits for profit. One identified attacker address, created in February 2026, reportedly profited over $16,000 in a single day by targeting just 7 markets. The attack severely undermines market maker confidence, threatens the platform's liquidity, and exposes a fundamental design flaw. While the community has developed monitoring tools, Polymarket team has not yet issued an official fix.

When 'Stability' Begins to Fluctuate: A Complete Review and Structural Analysis of the USD1 Depegging Incident

USD1, a stablecoin issued by World Liberty Financial (WLFI), experienced a brief depegging event on February 23, with its secondary market price dropping to around $0.98. WLFI attributed the incident to a "coordinated attack," claiming reserves and redemption mechanisms remained unaffected, and the price quickly recovered. The event raised questions about whether the depegging was a liquidity issue or a solvency crisis. Unlike TerraUSD's algorithmic collapse in 2022, USD1’s price dip appeared more related to temporary market liquidity stress rather than fundamental reserve failures. However, the incident highlighted that stablecoin stability relies not only on assets but also on market trust. USD1 operates under a centralized reserve model, where risks involve reserve transparency, asset liquidity, and market depth. In a low-liquidity, risk-averse market environment, even minor instability can trigger concerns about collateral devaluation, liquidations, and broader financial contraction. While the rapid price recovery suggests no systemic solvency issue, the event underscores how stablecoin depegging—even if temporary—can amplify market anxiety, reduce leverage, and increase funding costs. Trust, once questioned, takes time to restore, and credit repricing often precedes price changes in stressed markets.

WLFI Stablecoin USD1 has Recovered from Coordinated Attack

WLFI's stablecoin USD1 has recovered after a brief coordinated attack drove its value down to $0.994. The security and engineering teams successfully repelled the attack without any impact on the smart contract. Although the co-founders' X accounts were compromised, all holdings remained safe and fully backed. The attackers reportedly paid influencers to spread FUD and open short positions to profit from the decline. USD1 has retained its market position with a capitalization exceeding $4.74 billion, ranking fifth among stablecoins. Meanwhile, broader concerns linger for the stablecoin and crypto sectors as authorities debate potential cuts in interest rates amid recent U.S. tariff policy changes.

WLFI alleges coordinated attack as USD1 shrugs off brief depeg

World Liberty Financial (WLFI) alleged a coordinated attack against its USD1 stablecoin on 23 February, after the token briefly depegged below $1 amid heavy trading volume and social media speculation. The company claimed attackers compromised cofounder accounts, spread fear online, and opened large short positions to profit from volatility. USD1 quickly rebounded to its $1 peg, which WLFI attributed to its fully-backed mint-and-redeem mechanism. The price dip coincided with unverified rumors, including claims that cofounder Eric Trump had deleted WLFI-related posts, though no evidence supports this. While the incident highlights how sentiment can impact stablecoins, WLFI provided no technical proof of manipulation, and USD1's rapid recovery suggests a liquidity-driven event rather than a structural failure.

Ethereum’s Busy Network May Be Hiding A Security Problem: Analysts

Ethereum's high network activity may be partially driven by widespread "address poisoning" attacks, according to analysts. A recent upgrade reduced gas fees, enabling scammers to send tiny, worthless transactions to numerous wallets. These create fake entries in transaction histories, tricking users into copying fraudulent addresses and sending funds to attackers. Researchers warn users to verify full addresses, avoid copying from recent transactions, and treat unexpected small deposits as red flags. It's estimated that over $740,000 has been stolen through this method.

Industry Expert Predicts Complete Bitcoin Collapse – Here’s The Timeframe

Justin Bons, founder and CIO of CyberCapital, predicts Bitcoin could face a total collapse within the next 7 to 11 years. He argues that Bitcoin’s security model is fundamentally flawed due to its halving mechanism, which reduces block rewards for miners every four years. As rewards decline, miner revenue decreases, undermining the economic incentives that secure the network. Bons contends that rising hashrate does not equate to stronger security, as improved mining efficiency lowers the cost of potential attacks. He warns that within two to three halving cycles, the cost of executing a 51% attack could become economically viable, especially through double-spend attacks on exchanges. Without increasing Bitcoin’s fixed supply—a highly contentious change—the network may eventually become vulnerable to collapse.

Bank of Italy Warns ETH Price Crash Could Disrupt Ethereum Network

A Bank of Italy study warns that a severe crash in Ethereum's price could cause the entire network to fail, potentially freezing over $800 billion in assets, including stablecoins and tokenized bonds. The risk stems from Ethereum’s validator-based economy: if ETH’s value drops too low, validators may stop processing transactions due to unprofitable operations, halting the network’s ability to finalize transactions. This would render all on-chain assets immovable, even if they are inherently trustworthy. Additionally, a lower ETH price makes the network cheaper to attack, as the cost to manipulate transactions decreases significantly. In such a crisis, moving assets off-chain would be difficult due to fragile bridges and locked DeFi apps, with no central authority to intervene. The report emphasizes that since real financial assets are built on Ethereum, a crypto crash could spill over into traditional finance, and may lead regulators to require backup systems and external record-keeping.

After Three Days on Hotel Wi-Fi, My Crypto Wallet Was Drained

While on vacation, the author connected to an unsecured hotel Wi-Fi network without a password, only a captive portal login. After discussing cryptocurrency topics on a phone call in a shared space, an attacker nearby identified him as a crypto user with a Phantom wallet. The attacker executed a man-in-the-middle attack, injecting malicious code into a webpage the author visited. While using JupiterExchange for a swap, a fraudulent transaction approval request was triggered, disguised as a legitimate platform action. The author approved what appeared to be an authorization or session confirmation—not a direct fund transfer—granting the attacker permission to access his wallet. Days after leaving the hotel, the attacker drained his SOL, tokens, and NFTs. The author lost around $5,000 from a secondary hot wallet, emphasizing mistakes: using public Wi-Fi, discussing crypto in public, and approving transactions without thorough verification. He advises using mobile hotspots, avoiding public crypto discussions, and scrutinizing every wallet request.

Crypto Phishing Losses Crash By 83% In 2025 – Details

Crypto phishing losses plummeted by 83% in 2025, falling from $494 million to $83.85 million, with victim count dropping 68% to 106,106. Despite the decline, Web3 security firm Scam Sniffer warns this does not indicate reduced threat levels, as losses correlated with market activity—peaking in Q3 during high user engagement. A new threat emerged with EIP-7702 exploits, enabling bundled malicious transactions via account abstraction. Permit/Permit2 signatures remained the leading attack method, responsible for 38% of large-case losses. Major incidents included a $1.46 billion breach by the Lazarus group. While reported losses fell, attackers may be shifting to harder-to-track methods like private key theft or targeted social engineering.

Hundreds of Wallets Drained on EVM Chains With No Root Cause, ZachXBT Warns — $107K Lost So Far and Counting

Blockchain investigator ZachXBT warns of a coordinated attack draining hundreds of crypto wallets across multiple Ethereum Virtual Machine (EVM)-compatible chains, with no confirmed root cause yet identified. The incident has resulted in approximately $107,000 in losses so far, with the total continuing to rise. Each affected wallet lost relatively small amounts, typically under $2,000, suggesting a broad but low-value attack designed to avoid detection. ZachXBT flagged a suspicious address potentially linked to the activity. This follows a separate security incident over the Christmas holiday involving unauthorized withdrawals from self-custody wallets, which Trust Wallet later confirmed was related to its Browser Extension version 2.68. These incidents highlight ongoing security risks in the EVM ecosystem, despite long-term efforts to strengthen network resilience, such as the Ethereum Foundation's "Lean Ethereum" initiative aimed at improving security and scalability.
