Verified blockchain security incidents with original evidence and historical event dates.
Description of the event: NUMA was attacked on the Arbitrum chain, resulting in a loss of approximately $530,000. The attacker swapped all assets to ETH, bridged them to Ethereum mainnet, and deposited the funds into Tornado Cash.
Description of the event: R0AR has been exploited, with total losses amounting to approximately $780K. According to analysis by the SlowMist security team, the root cause of the exploit was the presence of a backdoor in the contract. During deployment, the R0ARStaking contract altered the balance (user.amount) of a specified address by directly modifying storage slots. Subsequently, the attacker extracted all funds from the contract through an emergency withdrawal function. R0AR stated in a tweet: “At this stage, we do not believe this to be an external exploit. One nefarious developer, external to the R0AR core team, is seemingly behind the drain. They have been removed from the project with all accesses revoked.”
Description of the event: The official X account of AI blockchain project DIN (@din_lol_) has been compromised by a hacker. Current posts from the account are not from the official team, and users are advised not to click any links or engage with related content. Additionally, the X accounts of DIN founder Harold and the DIN Foundation (@Foundation_DIN) have also been hijacked. The DIN team is actively addressing the incident and urges users to rely on official channels for further updates.
Description of the event: The decentralized perpetual futures exchange KiloEx was attacked, involving assets across multiple chains including BNB and Base. According to an analysis by the SlowMist Security Team, the root cause of the incident was the lack of access control checks in KiloEx's top-level contract (MinimalForwarder), which allowed the manipulation of oracle prices. Thanks to the active response from the project team and collaboration with SlowMist and others, all stolen assets were successfully recovered after 3.5 days of effort.
Description of the event: The official website of hybrid blockchain project Aergo is temporarily unavailable due to a DDoS attack. The technical team is actively working on the issue and aims to restore access as soon as possible. Aergo reminds users to stay alert for impersonation and scam attempts — the team will never initiate DMs or request funds or wallet information.
Description of the event: The ZKsync security team discovered that an admin account had been compromised, giving the hacker control of approximately $5 million worth of ZK tokens — the remaining unclaimed tokens from the ZKsync airdrop. The ZKsync Security Council sent an onchain message to the hacker on Monday, April 21st at 15:03 UTC. In an effort to resolve this matter in the spirit of safe harbor, they offered a 10% bounty for returning 90% of the funds involved in the exploit. On Wednesday, April 23rd at 14:39 UTC, 90% of the funds were returned to the Era and Ethereum L1 addresses controlled by the Security Council.
Description of the event: Jake Gallen, CEO of digital asset trading platform Emblem Vault, was hacked after a suspicious Zoom video call, resulting in the loss of over $100,000 worth of Bitcoin and Ethereum. The attacker posed as a YouTube content creator with over 90,000 subscribers and exploited Zoom’s default remote access settings during the interview to install malicious software named “GOOPDATE” on Gallen’s computer.
Description of the event: According to the SlowMist MistEye security monitoring system, a MEV bot (address: 0x49e27d11379f5208cbb2a4963b903fd65c95de09) has lost approximately 116.7 ETH due to a lack of access control.
Description of the event: According to the SlowMist MistEye security monitoring system, the NFT project Next Earth has suffered a reentrancy attack on Polygon.
Description of the event: According to an announcement from blockchain payment platform UPCX, unauthorized activity was detected in its management accounts. As a precaution, the platform has urgently suspended UPC deposits and withdrawals. The official statement assures that user assets remain unaffected, and an active investigation is underway to determine the cause of the incident, with further updates to follow. Earlier reports suggested that an unauthorized party had accessed UPCX’s official addresses. The attacker allegedly transferred a total of 18.4 million UPC (approximately $70 million) from three management accounts. On April 4, UPCX posted on Twitter that, despite differing reports from various sources, the project still retains control over 18,473,290 UPC. While the suspicious activity remains under investigation, the project team will proceed with the transfer of the relevant UPC at approximately 09:00 UTC on April 4, 2025.
Description of the event: According to an official announcement from DeFi asset management protocol Zapper, its .fi domain was hijacked via social engineering. The current zapper(.fi) page is malicious and should be avoided — users are strongly advised not to click on any related links.
Description of the event: According to the SlowMist MistEye security monitoring system, the leveraged trading project SIR.trading (@leveragesir) on the Ethereum chain has been attacked, resulting in a loss of over $300,000 in assets. The root cause of this hack is that the transiently stored value set using tstore in the function was not cleared after the function call ended. This allowed the attacker to exploit this characteristic by constructing specific malicious addresses to bypass permission checks and transfer tokens.
Description of the event: According to monitoring by SlowMist's security team, Min Token (MIN) is suspected to have been attacked on BSC, resulting in a loss of approximately $21,400.
Description of the event: An attacker using a flash loan attack stole $13 million in the Magic Internet Money token from the Abracadabra Money project. The attack was enabled by a bug in the platform's smart contracts, and the hacker ultimately made off with around 6,262 ETH.
Description of the event: RWA restaking platform Zoth suffered a $8.29 million hack after an attacker gained access to admin privileges that allowed them to modify the platform's smart contracts. The hacker "upgraded" the contract to a malicious version, then withdrew $8.45 million in USD0++, a token issued by the Usual protocol. After swapping the assets into various other tokens, they were left with 4,223 ETH (~$8.29 million).
Description of the event: The media platform Watcher.Guru, which focuses on cryptocurrency and financial market news, posted on X that its account was hacked today. Watcher.Guru is still investigating the specific method of the breach and has contacted X's official team for further clarification.
Description of the event: BNB-based memecoin launchpad Four.Meme was attacked. According to the SlowMist security team’s analysis, the attacker purchased a small amount of tokens before launch through the 0x7f79f6df function of Four.Meme, and used this feature to send tokens to a specified PancakeSwap Pair address that had not yet been created. This allowed the attacker to create the Pair and add liquidity without needing to transfer the yet-to-be-launched tokens to the Pair, bypassing the transfer restrictions (MODE_TRANSFER_RESTRICTED) that applied before the Four.Meme Token launch. Ultimately, the attacker was able to add liquidity at an unintended price to steal pool liquidity.
Description of the event: On March 18, the Simple Staking pools of Voltage Finance, a DeFi platform built on the Fuse Network, suffered an unauthorized withdrawal, resulting in a total loss of $171,027.20 in USDCE and $151,085.87 in WETH.
Description of the event: Kaito official representative Sandra (@sandraaleow) posted on X that Kaito AI founder Yu Hu and Kaito's X account have been compromised. However, no KAITO wallets have been affected.
Description of the event: Berally, a platform for social trading using AI agents within the Berachain ecosystem, is suspected to have been hacked. The official statement reads: “Partial information of the deployer's key was leaked, leading to the sell-off of all vesting tokens and withdrawal of funds from the liquidity pool. The dApp contract remains secure and unaffected by the hack, but please temporarily revoke access to the dApp and Staking. An investigation is underway, and an update will be provided as soon as possible.”
