Odaily News: According to monitoring by Galaxy's Head of Research, the COLDCARD Wave 3 attacker has moved stolen funds for the first time, exchanging them for ETH via the THORChain cross-chain DEX. This marks the first on-chain transfer of funds from the original hacker address across Waves 1, 2, or 3.
According to CoinDesk, US cybersecurity firm CrowdStrike has partnered with federal law enforcement agencies to successfully dismantle the Russian botnet Sality, which has been operating for over two decades. Over the past eight years, the network has continuously stolen cryptocurrency through clipboard hijacking; its core payload, "EggJagger," resides on infected machines, monitoring the user's clipboard. Once a Bitcoin or Ethereum wallet address is detected, it is replaced with the attacker's address, causing victims to unknowingly complete transfers. Sality employs a decentralized P2P architecture with no central server, checking node online status every 40 minutes, and self-propagates via network-shared drives and USB devices. By exploiting an authentication vulnerability, CrowdStrike replaced legitimate node addresses with those of its own servers, successfully severing the network connections of over 15,000 infected machines. The operation was demonstrated live at the Day Zero summit in Las Vegas. Estimates indicate that the attackers stole at least 12.1 million rubles (approximately $150,000) over the eight-year period. Undisturbed crypto assets appreciated alongside the broader market, reaching a value of roughly $1.35 million by early 2025. Security experts advise users to always verify the first and last characters after pasting a wallet address to defend against such attacks.
Odaily News: CrowdStrike, in coordination with the U.S. Department of Justice, announced the dismantling of the Sality peer-to-peer botnet, isolating over 15,000 infected devices worldwide. The network has been active since 2003, and over the past eight years has primarily deployed a clipboard hijacking tool known as EggJagger to steal funds from Bitcoin and ETH transfers. EggJagger monitors cryptocurrency wallet addresses copied by victims and replaces them with addresses controlled by the attackers, redirecting transfer funds to the attackers. CrowdStrike estimates that this tool alone has stolen at least $150,000 in crypto assets; since most of the funds were not moved, the value of the associated holdings rose to approximately $1.35 million in January 2025. The U.S. Department of Justice, FBI, and Defense Criminal Investigative Service have seized related domains within the U.S., while police in Bulgaria, Hungary, and Romania have also shut down infrastructure in Europe. Currently, infected devices have been redirected to traffic reception servers controlled by CrowdStrike, but the original malware on the devices remains active until manually removed.
Aquifer, an automated market maker within the Solana ecosystem, suffered losses of approximately $2.5 million after its wallet addresses were compromised. The incident appears to stem from leaked wallet credentials rather than a smart contract vulnerability. The attackers operated across multiple blockchains, including Ethereum and Solana, suggesting potential cross-chain fund transfers. As of now, the specific cause of the wallet access breach and the progress of asset recovery remain unclear.
According to PeckShieldAlert, the cryptocurrency industry saw 50 major attack incidents in August 2026, an increase of 67% over the 30 incidents in July. Total losses reached approximately $136.3 million, a 49.5% decrease from the $270 million in July. The Tectonic.cro incident caused approximately $74 million in losses, ranking as the fourth-largest crypto theft of the year, behind only attacks associated with Drift, KelpDAO/LayerZero, and COLDCARDwallet. The attacker managed to cross-chain only around $6 million to Ethereum before Cronos suspended its entire network, leaving the rest of the funds mostly stranded on Cronos. The attacker has since started laundering the illicit proceeds and bridging a portion to Bitcoin, amounting to roughly $200,000 to date. Other significant attack incidents in August involved Moonwell, Termlabs, Coinsbuy, TAC, Injective, MANTRA, BounceBit, Cosmos Labs, and aquifer.
PeckShieldAlert monitoring indicates that Tectonic was attacked on the Cronos Network, resulting in total losses of approximately $74 million. Following the incident, Cronos has halted the entire chain. Prior to the halt, the attacker successfully bridged only about $6 million to Ethereum, while the remaining approximately $60 million remains stranded on Cronos, with an additional $8 million in funds held in Cronos addresses.
Odaily News: The sandwich attack bot operated by JaredfromSubway.eth has extracted a cumulative total of 117,007 ETH since March 2023, worth approximately $295 million at current prices. In June 2026, an anonymous attacker deployed 66 counterfeit token contracts, exploiting the bot's automated trading logic to steal at least $7.5 million in ETH and stablecoins, and funneled the funds into Tornado Cash. The stolen assets have not yet been recovered.Sandwich attacks are a form of Maximal Extractable Value (MEV): the bot monitors large transactions in Ethereum's public mempool, buys ahead of the target transaction, and sells after the transaction pushes the price up, capturing profits from the spread. The bot's primary contract had received a cumulative total of 117,007 ETH as of August 28.MEV-Boost block construction is centralized among a small group of participants, with relay.ultrasound.money, Titan Relay, and bloXroute regulated relays collectively forwarding approximately 85% to 88% of related blocks within a 24-hour window; Titan's builder independently assembled 50.3% of the blocks. Monthly sandwich attack extraction amounts have declined from approximately $10 million in late 2024 to roughly $2.5 million in October 2025. (Bitcoin.com News)
Odaily News, Avici announced that its card partner Rain discovered today a vulnerability in an old Solana card contract used by Avici and a few other projects. The relevant contract has now been upgraded across all projects, and no further unauthorized activity has been detected. This incident only affected the standalone Solana contract used to hold post-deposit card balances; users' Avici wallets and card balances are isolated from each other, and funds in Solana and EVM self-custody wallets are safe and unaffected. Upon review, a total of 1,685 users were affected, with combined card balances of approximately $500,900. Avici has committed to fully refunding card balances to all affected users and has filed a report with the FBI's Internet Crime Complaint Center (IC3). Previously reported, Avici, a crypto banking project, saw its native token AVICI allegedly suffer a hacker attack, with losses of approximately $1.02 million. The attacker transferred 10,000 SOL stolen from the project to another wallet, converted it into approximately $1.02 million USDC, and then swapped the funds into approximately 418 ETH via cross-chain operations.
Odaily News, according to Onchain Lens monitoring, AVICI has been attacked, with losses of approximately $1.02 million. An address transferred 10,000 SOL to another wallet, exchanged it for approximately $1.02 million USDC, and then bridged the funds across chains to exchange for about 418 ETH.
According to Cointelegraph, open-source wallet provider OneKey stated that its security team successfully reproduced a "transaction replacement attack" targeting the legacy Ledger Ethereum app version 1.22.1 in a laboratory environment. This vulnerability could allow attackers to replace transactions awaiting signature while users review legitimate ones, though successful exploitation requires controlling communication between the device and the host, such as through malware, compromised wallet software, or malicious websites.
Odaily News: 0xbow.io, a privacy and regulatory compliance tool supported by the Ethereum Foundation, has awarded a $5,000 bounty to researcher ross.wei for disclosing a vulnerability in the Privacy Pools v1 SDK. The vulnerability reduced the entropy of user account master key generation and was fixed in March. The team has provided a migration process, and no user funds were lost.
blockchain gaming platform The Sandbox has announced it will compensate users who held bridged SAND on Base or BNB Smart Chain prior to the August 21 bridge vulnerability exploit at a 1:1 ratio. The compensation will be paid using Ethereum-based SAND from the project treasury, with no new tokens being minted.The attack resulted in approximately 14.744 million SAND being stolen from the Ethereum treasury, valued at around $700,000. The claims process is expected to open within two weeks and will last for two weeks; two centralized exchanges holding over 72% of eligible balances will directly distribute compensation to affected customers.The Sandbox stated that the attacker exploited a configuration vulnerability in SAND contracts on Base and BNB Chain, becoming the sole validator of bridge messages and minting unbacked tokens. Additionally, over 339 trillion unbacked SAND tokens were minted across the two networks, but these have been quarantined and cannot be bridged or exchanged. SAND on Ethereum and Polygon was unaffected, and the compromised bridge contracts will be permanently decommissioned. (Cointelegraph)
According to the latest report released by Grayscale Research Director Zach Pandl, as U.S. federal debt surpasses $40 trillion, Bitcoin's 90-day correlation with the Nasdaq 100 Index has dropped from over 60% to approximately 33%, while its correlation with gold has risen from near zero at the start of the year to above 50%, indicating that Bitcoin is shifting from a high-beta risk asset to an inflation-resistant store of value. Grayscale believes that expanding fiscal deficits and rising long-end interest rates will drive investors toward scarce alternative assets, positioning Bitcoin, Ethereum, and Zcash as primary beneficiaries. Among them, Zcash, featuring financial privacy, quantum resistance, and cross-chain interoperability, is considered to have the potential to challenge Bitcoin's network effect, despite its market capitalization currently accounting for less than 1% of Bitcoin's. Additionally, Grayscale notes that the current Bitcoin bear market has persisted for roughly 10 months, approaching the historical average bear market cycle of 11–12 months. Coupled with a macroeconomic environment that is becoming increasingly supportive, it suggests that current prices may represent a favorable entry point for long-term investors.
Odaily News: OneKey Anzen has reproduced the Ledger vulnerability and discovered that Ledger Ethereum app version 1.22.1 contains a transaction replacement vulnerability. When an affected user is attacked, the hardware screen still displays transaction A under review, but the device may sign transaction B, which the user never viewed. OneKey Anzen stated that the issue stems from a race condition between the transaction display logic and the underlying buffer, with the attack requiring the host side to already be compromised by a malicious DApp or intermediary software. Ledger's CTO previously responded that a fix had been rolled out approximately two weeks ago, and users simply needed to update the app. Public information shows that the official tag for version 1.22.2 on Ledger's GitHub appeared on August 24. Ledger's official website states that the issue has been fixed through app-level checksums and SDK-layer patches, with Ledger Secure SDK v26.6.1 released on August 21, and the related apps have been rebuilt and republished. Users need to update the app via Ledger Live — updating only the device firmware will not complete the fix. Ledger stated that there is currently no evidence that this vulnerability has been actively exploited.
GoPlus Security released a security alert stating that on August 25, realio[.]fund, a project under Realio Network, was attacked. The attacker took control of the platform's signing system and moved treasury and custody wallet assets across Ethereum, BNB Chain, Algorand, Stellar, and the Realio native chain. A total of approximately 127.9 million RIO tokens worth around $6.2 million were affected, with the attacker having cashed out approximately $317,000 so far.
Odaily News, The Sandbox has released a post-mortem report on the August 22 vulnerability incident. The report shows that attackers exploited vulnerabilities in contracts related to cross-chain configurations on Base and BNB Smart Chain (BSC), stealing 14,742,341.84 SAND from the Ethereum treasury, accounting for approximately 0.5% of the maximum supply, with an estimated economic impact of approximately $1.4968 million, of which about $987,000 was actually retained by the attackers. The Ethereum mainnet and Polygon network were not affected. Until further notice, please do not purchase or send SAND on Base or BNB Smart Chain. Contracts deployed on Base and BNB Smart Chain have been permanently deactivated and will not be reopened. The Sandbox stated that the team has reported the attacker's wallet address to blockchain analysis firms TRM Labs and Chainalysis, and has communicated directly with relevant exchanges. The Sandbox also announced a compensation plan, which will compensate wallets that legitimately held cross-chain SAND on Base or BSC prior to the incident at a 1:1 ratio in Ethereum SAND. Compensation funds will come from The Sandbox treasury, with no new tokens issued. The claim process will open within the next two weeks and remain open for two weeks.
Odaily News: Ledger Chief Technology Officer Charles Guillemet stated that a smart contract security company recently claimed to have discovered a vulnerability in the Ledger Ethereum app. The Ledger Ethereum app did previously contain a vulnerability related to certain Clear Signing processes, but it was identified by Ledger's in-house security research team, Donjon, using an AI-driven vulnerability research tool, and was fixed and deployed two weeks ago. The security company in question only contacted Ledger's bug bounty program after the fix had already been completed, failing to follow responsible disclosure procedures and without communicating with the bug bounty team, then published content implying that the issue remained unresolved. Guillemet stated that users who promptly update their Ledger device firmware, Ledger apps, and related software will receive the latest security fixes.
According to Odaily, an investigation into the security vulnerability exploit of the Cosmos EVM module reveals that the primary attacker (0x9AE7) purchased $250,000 worth of NES and bridged it to Nesa Chain, exploiting a balance vulnerability to inflate holdings to 200 times their original size, then bridged approximately $50 million worth of NES back to Ethereum. The attacker's initial funding for the wallet originated from Monero. Through multiple wallets, the attacker exchanged NES for ETH on DEXs and deposited the proceeds into centralized exchanges. Due to rapid liquidity withdrawal, most exchanges suffered extreme slippage, and the attacker ultimately sold for only $315,000, netting a profit of approximately $60,000 after deducting costs.
According to monitoring by PeckShield, the Term Labs attacker address deposited 300 ETH into Tornado Cash, worth approximately $741,000.
Odaily News: Ethereum client Besu has fixed 5 security vulnerabilities discovered by blockchain security firm CertiK in version 26.7.1 released on July 27, and published 4 detailed security advisories on August 14. Vulnerability details were disclosed after a delay to allow node operators to complete upgrade deployments.Jialiang Chang, Director of Security Engineering and Senior Audit Partner at CertiK, stated that the arrangement of releasing patches first and details later provided an 18-day buffer period, allowing node operators to identify affected deployments, test new versions, and coordinate with validators or consortium participants to complete upgrades.The vulnerabilities involve block broadcast handling, caching of future-height consensus proposals, WebSocket subscription limits, and JSON-RPC filter creation. If left unpatched, attackers could exhaust node memory or thread resources, impacting node availability and consensus processing.Using the Chain Scan methodology, CertiK conducted adversarial testing on peer-to-peer, HTTP RPC, WebSocket RPC, and consensus interfaces in a private multi-node test network, and provided reproducible testing tools to the Besu team. CertiK is updating Chain Scan to expand round-the-clock multi-node testing on public chain networks. (Bitcoin.com News)
