The fix was committed to a temporary private fork of the Wormhole repository (it is now published to the public repository). Now that you have wrapped tokens in your wallet, you can trade them on an exchange for native assets. The hackers Solana wallet currently holds 432,662 SOL ($44 million). Or plainly The team continued working to address this problem, and maintained frequent communications with Wormhole network community members. On Feb 2, 2022, an attacker exploited a signature verification vulnerability in the Wormhole network to mint 120k Wormhole-wrapped Ether on Solana. Wormhole is a decentralized, cross-chain message passing protocol. these guys are legit, and i think problems like this will slowly start to be come less infrequent. In addition, open lines of communication were established with the Wormhole Guardians running the network. Use this tutorial to bridge your assets between Terra and other chains using Wormhole. It is also reminiscent of the Poly Network hack last August wherein$610 million in crypto was stolenoff the platform. If you are interested in token rewards or have any idea how to improve the platform, please contact us! Click here to see available markets for wrapped tokens. Build a relayer container image for each release, cosmwasm: move chain id and fee denom to storage, cloud_functions: Added LOAD_CACHE env variable, Add the opencontainers source label to the relayer Dockerfile.
The deployed fix performs the same check on the instruction sysvar account, but was developed independently. Tokens are created in each chain, for example, on Ethereum they are ERC20 and on Solana they are SPL tokens. Introducing Soluna, the gateway to Anchor interest-bearing assets on Solana. Select a Source chain and a Target chain from the dropdown choices.
Higher speeds mean that validators can process an increased number of transactions in a block. Ongoing verification and chain forensics work by multiple teams were done to verify the upgrade. MODS or Community Managers will NEVER DM you first regarding your funds/wallet. 05:53 UTC Governance reached + consensus and the upgrade was executed on Solana. (LogOut/ I use celer networks cbridge.

Seems like a lazy hack rushed it with how flawed their system was. link. 20:14 UTC The plan was agreed to by the Guardians on how to safely bring their nodes back online and submit their governance votes. This new version of Wormhole is separate from the original native bridge built on Solana. This is a transition away from being a native L1 bridge from Solana to Ethereum. The new version of Wormhole has its own consensus mechanism, called Guardians. This enables users to access their messages on a different chain. Explained: The Wormhole Hack (February 2022), Halborn MetaMask Demonic Vulnerability Discovery, The attacker creates a validator action approval (VAA) with a call to post_vaa, This VAA was used in a call to complete_wrapped to mint the 120,000 ETH extracted in the attack, The attacker legitimately extracted the minted tokens from the bridge. However, the verify_signatures function used the load_instruction_at function which outputs an instruction that is derived from the input data (which is the data of the instruction sysvar account). This subreddit is operated by the Solana Foundation. This opens the door for connections between networks like token or NFT swaps or connections between a single chain to a specific set of chains like price feeds or data sources. 22:07 UTC The Neodyme team, which had been working on the fallback plan to upgrade using the exploit, succeeded in building and testing a working prototype. Learn on the go with our new app.

This bug allowed the attacker to forge a message from the Guardians to mint Wormhole-wrapped Ether. Shit happens all the time. Ongoing monitoring and early detection of incidents. We do our best for you! Thus, all signatures in the signature_set are marked as true which means it has all valid signatures. Wormhole Bridge is a bridge between blockchains, it allows for transferring assets from one blockchain to another. Follow the steps in your wallets browser extension to complete the transaction. No other assets or chains served by Wormhole have been reported affected, but smart contract auditing firm Certik said in a report today that it is possible that Wormholes bridge to the Terra blockchain shares the same vulnerability as their Solana bridge.. Certus One initially introduced the Wormhole L1 native bridge in 2020. Press J to jump to the feed. Therefore, a workaround was tested that would allow Guardians to submit governance votes without enabling token transfers. 11:27 UTC Consensus was reached on starting the network back up. Meaning that older additions will not work. Click here to see available markets for wrapped tokens. The actual flow of the attack was: The vulnerability that made the attack possible was a failure to perform proper signature verification in the VAA creation process. Change), You are commenting using your Facebook account. For outgoing transfers, native tokens will be either be locked into a smart contract or burned and represented as the wrapped tokens.

This check ensures that Wormhole-wrapped tokens are backed 1:1 by tokens in the source chain contract. For incoming messages users will need to send a message containing a payload. This requires trust in the oracle network rather than a blockchain, complex and flexible to solve the traditional problems of bridges, can build token bridges on top of these foundations, unlock or mint tokens, register the token bridge contract, upgrade the contract, or send a metadata message. Make sure your target wallet has tokens to pay fees in to redeem your tokens. Do not trust DMs from anyone offering to help/support you with your funds (Scammers)! At this point, the attacker could no longer create new fraudulent Wormhole messages. Contract Developer: Sir Tris (Clifford Inu) Heavy marketing planned prior to launch day. They are embarking on a quest to aid developers in providing more DeFi application users and a more robust Web 3 experience. Basically, the instruction sysvar program was never checked. Cryptocurrencies are a high-risk investment, no matter how fancy. This addition makes it a stand-alone bridge that has features and flexibility to connect to any other network, along with allowing creative developers the ability to build their own dApps on the bridge. Cross-chain interoperability protocol connecting high value blockchains. Any arbitrary Wormhole message with Solana as the destination chain could be signed by an attacker, including messages to mint wrapped Wormhole tokens on Solana. This is going to hurt future fundraising if they don't get their sh*t together and start being more careful and slower in design. Solana is an L1, meaning that it is a layer one protocol, allowing developers to use Solanas features to build applications. 13:39 UTC A tweet was sent from the official Wormhole account to inform the community that the network was back online. Didn't Alameda buy Ren Protocol to use them as the official Solana bridge? Blockchain-based platform reinvents omnichain interoperability through validated event data, Ukrainian crypto and blockchain firms survive despite ongoing conflict. The Latest News from Research at Kudelski Security. The hacker has since used some funds to buy SportX (SX), Meta Capital (MCAP), Finally Usable Crypto Karma (FUCK) and Bored Ape Yacht Club Token (APE).

Additional communications were sent to partners and projects. With the launch of the Wormhole mainnet, the bridge is expanding beyond Solana to include other L1s to bring liquidity from Solana, Ethereum, Terra, and Binance Smart Chain. The attacker passed in this account rather than the Instructions sysvar. This contrasts with Ethereum, where there are only so many transactions in a block, driving up gas prices and taking time to process transactions. There are two ways that tokens are transferred over the bridge.
You have just used Wormholes Portal Token Bridge. The Guardians are also responsible for governing the Wormhole network. The hack took place at 6:24 pm UTC on Wednesday. This transaction will produce a transfer message to the bridge thus sending the message on to the other chain. The actual extraction of 120k ETH from the Wormhole bridge came at the end of a series of events. Click Connect to connect your Terra Station wallet. Cross-chain transfer of assets between multiple networks can be realized through Wormhole. These tokens can be traded on an exchange for native assets. If you find it, please, contact us at [emailprotected], We're not found any audits or exploits.
Once a signature_set is created, the function post_vaa will check if it has enough number of signatures to reach the consensus to post a Validator Action Approval (VAA). 00:32 UTC In close coordination with the other teams, and after further improvements, Neodyme successfully ran the upgrade to close the vulnerability. 00:32 UTC The vulnerability was fixed. This process relies on information contained in the instruction sysvar account, which is trusted because it is populated by the Solana runtime. It is because a malicious user could create accounts with arbitrary data and then pass these accounts to the program in place of valid accounts. The hacker has not responded at the time of writing. (LogOut/ The Wormhole team contacted the hacker through their Ethereum address, offering to let the hacker keep $10 million worth of funds stolen if the remaining funds are returned. The Wormhole network is back online and fully operational as of 13:29 UTC, Feb 3, 2022. Please stay tuned and wait for our updates and news. Be sure to have enough tokens in your wallets to pay for fees. This philosophy we have in Solana to move fast and break things is not a good one in critical Blockchain infrastructure projects with billions on the line. Why did they decide to abandon Ren and use this wormhole project which clearly has poor opsec. Subscribe to receive Figment and Web 3 ecosystem updates. The Wormhole team uses an oracle/smart contract-based system. Welcome to the official Solana subreddit. The connection between the fix and the toolchain upgrade only became clear in the aftermath of the exploit. The attacker may have noticed the vulnerability because this commit was public, or they may have felt forced to execute the attack once the fix was merged. This attack is an example. The attacker created a fake version of the Instructions sysvar that was an account created previously that called the Secp256k1 contract. It enables applications to send messages from one chain to another. While the commit did fix the vulnerability, it was a coincidental byproduct of the toolchain upgrade. I am a bot, and this action was performed automatically. The attacker minted 120,000 wETH on Solana, then redeemed 93,750 wETH for ETH worth $254 million onto the Ethereum network at 6:28 pm UTC. spoken - this is a very complex piece of software which targets a bleeding-edge, experimental smart contract runtime. Tank Wars General Update | March 31, 2022, Accounting mechanism to isolate risks to individual chains. It had multiple audits before release. Sounds like the VCs bailing out the retail users who used the wormhole by replacing the ETH. ETH will be added over the next hours to ensure wETH is backed 1:1. After your tokens have been sent, you can receive them on the target chain by clicking Redeem. Different versions of Solidity is used: - Version used: ['^0.8.0', '^0.8.2'] - ^0.8.0 (#6) - ^0.8.0 (#93) - ^0.8.0 (#313) - ^0.8.0 (#402) - ^0.8.2 (#421) - ^0.8.0 (#617) - ^0.8.0 (#681)Use one Solidity version. xApp Book. 18:13 UTC Jump Crypto confirmed that it provided the Ether to refill the contract. The attack on Wormhole is the second-largest reported hack after Poly Network (https://research.kudelskisecurity.com/2021/08/12/the-poly-network-hack-explained/). Portal is a token bridge constructed on top of the Wormhole network. They have over a billion in TVL and been live for a couple years now. It is completely redesigned with more application. solana should be careful who they promote however. whitepapers: Add FromAddress and remove Fee, pyth2wormhole: build + deploy program into local devnet, staging/algorand: apply global Apache 2 license, Add scripts and readme to deploy and verify terra contracts. Above that, Guardians manage transactions between each blockchain. In February 2022, Wormhole, a token bridge between Ethereum and Solana, was the victim of the second most expensive DeFi hack to date. Understand theyre looking to support SOL in Q1 this yr. After changing the signature of a malicious message, the attacker was able to transferred from Solana tokens which were identical to legitimate tokens through the Wormhole bridge to Ethereum. Unable to find whitepaper link on the website, LASER DESK This is again a costly lesson for all blockchain developers, especially for Solana program developers. Related: $2.5B in stolen BTC from Bitfinex hack awakens. Instead of swapping or converting assets directly, Wormhole locks your source assets in a smart contract and mints new Wormhole-wrapped assets on the target chain. When prompted, click Confirm to confirm the transfer.
If you find something or have any information about it, please, contact us at [emailprotected], Limits wasn't found. just saw the thread with the actual error. See docs/operations.md for node operator instructions. The Wormhole team has assured the community that its Ether (ETH) supply would be replenished to ensure wETH is backed 1:1, but there is no word yet on where those funds will come from or when. Current L1s that do not have the ability to connect to each other rely on bridges to be able to communicate across chains. This version of the toolchain deprecated the load_current_index and load_instruction_at methods in favor of checked variants. This is the second smart contract exploit on a token bridge in a week. I hope not, because if it was it was a real crap audit, and being audited wouldn't mean much. To learn about how to use and build on Wormhole read the Docs or take a look at the The Wormhole token bridge experienced a security exploit on Wednesday, resulting in the loss of 120,000 Wrapped Ether (wETH) tokens ($321 million) from the platform. L1s need additional help from other networks to increase their DeFi use cases. These tokens were not backed by Ether deposits on the Ethereum side of the Portal bridge. Please contact the moderators of this subreddit if you have any questions or concerns. The Wormhole team is ready to expand into other domains and provide incentives for their own set of validators in addition to providing liquidity to other ecosystems. This hack demonstrates the importance of secure coding practices and an in-depth security audit for software security. The root cause of the exploit was a bug in the signature verification code of the core Wormhole contract on Solana. 19:40 UTC Two teams started working in parallel to close the vulnerability focusing on two different approaches. Low level call in Address.sendValue(address,uint256) (#144-149): - (success) = recipient.call{value: amount}() (#147)Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#212-223): - (success,returndata) = target.call{value: value}(data) (#221)Low level call in Address.functionStaticCall(address,bytes,string) (#241-250): - (success,returndata) = target.staticcall(data) (#248)Low level call in Address.functionDelegateCall(address,bytes,string) (#268-277): - (success,returndata) = target.delegatecall(data) (#275)Avoid low-level calls.

The developers use of a single, deprecated function (which doesnt check addresses) enabled a forged signature pass without verification. In Solana, the instruction_sysvar account contains all instructions of the message of the transaction that is being processed. also, this has nothing to do with solana. Uniswap had 3 audits before it deployed v3 and aave 3 audits before deploying v2 due to the amount of funds involved. The wormhole network was exploited for 120k wETH. See DEVELOP.md for instructions on how to set up a local devnet, CONTRIBUTING.md for instructions on how to contribute to this project, and SECURITY.md for more information about our security audits and bug bounty program. The goal of the project is to create and publish distributed applications that do not require third party trust. The network is operated by a decentralized group of nineteen Guardians who sign each transmitted message to attest to its authenticity. Now, audited and live, SOL and ERC 20 token holders can transfer their assets between ecosystems not just Solana and Ethereum. If the call is meant for a contract, check for code existence. More precisely, it is a token bridge and a NFT bridge. 03:42 UTC The team introduced safeguards for the Solana-side Portal (token bridge) to blacklist the fraudulent Wormhole messages to prevent the attacker from stealing additional funds. To prevent further exploits, Wormhole node operators temporarily stopped relaying messages from on-chain contracts, then upgraded the contract to fix the vulnerability. these guys are not "smart" engineers if they are letting this happen. The issue in the exploitable version was that the verify_signatures function did not assert that the user provided account was the special instruction sysvar. It is common practice in DeFi and infrastructure projects to get multiple audits for high tvl or critical dapps. See Live Contracts for current testnet and mainnet deployments of The first approach would upgrade the contract using the in-protocol governance mechanism. This new Wormhole bridge has a vast amount of flexibility in the Web 3 space. If you find it, please, contact us to [emailprotected] (include the name of the bridge in the subject line of your e-mail), Bridge token wasn't found. 13:08 UTC Jump Crypto replenished the contract with 120k ETH, restoring full collateral. Connect your target chain wallet by clicking Connect. If you have any information, please, contact us [emailprotected]. Thanks for your patience. In addition, a smart contract (or program on Solana) manage each token on each chain.
Someone hired to look for security holes or back doors might find one, say nothing, then exploit it. Jump Crypto has recapitalized the contract to ensure that all Wormhole-wrapped Ether on every chain is fully backed. Basically, the wormhole program obtains the set of signatures from the prior instruction via the instruction sysvar program (in which its address is inputted by the user). The check that Secp256k1 was called previously passed (even though it was in a completely different context), so the signatures were believed to have been properly verified. Users can specify arbitrary input accounts when calling a function on Solana. Wormhole is targeting chains that do not have light clients or chains that otherwise could be IBC compatible it is designed to connect to a number of high-value chains focused on decentralized finance.

The attacker passed in this account rather than the Instructions sysvar. This contrasts with Ethereum, where there are only so many transactions in a block, driving up gas prices and taking time to process transactions. There are two ways that tokens are transferred over the bridge.
You have just used Wormholes Portal Token Bridge. The Guardians are also responsible for governing the Wormhole network. The hack took place at 6:24 pm UTC on Wednesday. This transaction will produce a transfer message to the bridge thus sending the message on to the other chain. The actual extraction of 120k ETH from the Wormhole bridge came at the end of a series of events. Click Connect to connect your Terra Station wallet. Cross-chain transfer of assets between multiple networks can be realized through Wormhole. These tokens can be traded on an exchange for native assets. If you find it, please, contact us at [emailprotected], We're not found any audits or exploits.
Once a signature_set is created, the function post_vaa will check if it has enough number of signatures to reach the consensus to post a Validator Action Approval (VAA). 00:32 UTC In close coordination with the other teams, and after further improvements, Neodyme successfully ran the upgrade to close the vulnerability. 00:32 UTC The vulnerability was fixed. This process relies on information contained in the instruction sysvar account, which is trusted because it is populated by the Solana runtime. It is because a malicious user could create accounts with arbitrary data and then pass these accounts to the program in place of valid accounts. The hacker has not responded at the time of writing. (LogOut/ The Wormhole team contacted the hacker through their Ethereum address, offering to let the hacker keep $10 million worth of funds stolen if the remaining funds are returned. The Wormhole network is back online and fully operational as of 13:29 UTC, Feb 3, 2022. Please stay tuned and wait for our updates and news. Be sure to have enough tokens in your wallets to pay for fees. This philosophy we have in Solana to move fast and break things is not a good one in critical Blockchain infrastructure projects with billions on the line. Why did they decide to abandon Ren and use this wormhole project which clearly has poor opsec. Subscribe to receive Figment and Web 3 ecosystem updates. The Wormhole team uses an oracle/smart contract-based system. Welcome to the official Solana subreddit. The connection between the fix and the toolchain upgrade only became clear in the aftermath of the exploit. The attacker may have noticed the vulnerability because this commit was public, or they may have felt forced to execute the attack once the fix was merged. This attack is an example. The attacker created a fake version of the Instructions sysvar that was an account created previously that called the Secp256k1 contract. It enables applications to send messages from one chain to another. While the commit did fix the vulnerability, it was a coincidental byproduct of the toolchain upgrade. I am a bot, and this action was performed automatically. The attacker minted 120,000 wETH on Solana, then redeemed 93,750 wETH for ETH worth $254 million onto the Ethereum network at 6:28 pm UTC. spoken - this is a very complex piece of software which targets a bleeding-edge, experimental smart contract runtime. Tank Wars General Update | March 31, 2022, Accounting mechanism to isolate risks to individual chains. It had multiple audits before release. Sounds like the VCs bailing out the retail users who used the wormhole by replacing the ETH. ETH will be added over the next hours to ensure wETH is backed 1:1. After your tokens have been sent, you can receive them on the target chain by clicking Redeem. Different versions of Solidity is used: - Version used: ['^0.8.0', '^0.8.2'] - ^0.8.0 (#6) - ^0.8.0 (#93) - ^0.8.0 (#313) - ^0.8.0 (#402) - ^0.8.2 (#421) - ^0.8.0 (#617) - ^0.8.0 (#681)Use one Solidity version. xApp Book. 18:13 UTC Jump Crypto confirmed that it provided the Ether to refill the contract. The attack on Wormhole is the second-largest reported hack after Poly Network (https://research.kudelskisecurity.com/2021/08/12/the-poly-network-hack-explained/). Portal is a token bridge constructed on top of the Wormhole network. They have over a billion in TVL and been live for a couple years now. It is completely redesigned with more application. solana should be careful who they promote however. whitepapers: Add FromAddress and remove Fee, pyth2wormhole: build + deploy program into local devnet, staging/algorand: apply global Apache 2 license, Add scripts and readme to deploy and verify terra contracts. Above that, Guardians manage transactions between each blockchain. In February 2022, Wormhole, a token bridge between Ethereum and Solana, was the victim of the second most expensive DeFi hack to date. Understand theyre looking to support SOL in Q1 this yr. After changing the signature of a malicious message, the attacker was able to transferred from Solana tokens which were identical to legitimate tokens through the Wormhole bridge to Ethereum. Unable to find whitepaper link on the website, LASER DESK This is again a costly lesson for all blockchain developers, especially for Solana program developers. Related: $2.5B in stolen BTC from Bitfinex hack awakens. Instead of swapping or converting assets directly, Wormhole locks your source assets in a smart contract and mints new Wormhole-wrapped assets on the target chain. When prompted, click Confirm to confirm the transfer.
If you find something or have any information about it, please, contact us at [emailprotected], Limits wasn't found. just saw the thread with the actual error. See docs/operations.md for node operator instructions. The Wormhole team has assured the community that its Ether (ETH) supply would be replenished to ensure wETH is backed 1:1, but there is no word yet on where those funds will come from or when. Current L1s that do not have the ability to connect to each other rely on bridges to be able to communicate across chains. This version of the toolchain deprecated the load_current_index and load_instruction_at methods in favor of checked variants. This is the second smart contract exploit on a token bridge in a week. I hope not, because if it was it was a real crap audit, and being audited wouldn't mean much. To learn about how to use and build on Wormhole read the Docs or take a look at the The Wormhole token bridge experienced a security exploit on Wednesday, resulting in the loss of 120,000 Wrapped Ether (wETH) tokens ($321 million) from the platform. L1s need additional help from other networks to increase their DeFi use cases. These tokens were not backed by Ether deposits on the Ethereum side of the Portal bridge. Please contact the moderators of this subreddit if you have any questions or concerns. The Wormhole team is ready to expand into other domains and provide incentives for their own set of validators in addition to providing liquidity to other ecosystems. This hack demonstrates the importance of secure coding practices and an in-depth security audit for software security. The root cause of the exploit was a bug in the signature verification code of the core Wormhole contract on Solana. 19:40 UTC Two teams started working in parallel to close the vulnerability focusing on two different approaches. Low level call in Address.sendValue(address,uint256) (#144-149): - (success) = recipient.call{value: amount}() (#147)Low level call in Address.functionCallWithValue(address,bytes,uint256,string) (#212-223): - (success,returndata) = target.call{value: value}(data) (#221)Low level call in Address.functionStaticCall(address,bytes,string) (#241-250): - (success,returndata) = target.staticcall(data) (#248)Low level call in Address.functionDelegateCall(address,bytes,string) (#268-277): - (success,returndata) = target.delegatecall(data) (#275)Avoid low-level calls. Click Select a token and choose from the available tokens in your wallet. This is a place to post any information, news, or questions about the Solana blockchain.

The developers use of a single, deprecated function (which doesnt check addresses) enabled a forged signature pass without verification. In Solana, the instruction_sysvar account contains all instructions of the message of the transaction that is being processed. also, this has nothing to do with solana. Uniswap had 3 audits before it deployed v3 and aave 3 audits before deploying v2 due to the amount of funds involved. The wormhole network was exploited for 120k wETH. See DEVELOP.md for instructions on how to set up a local devnet, CONTRIBUTING.md for instructions on how to contribute to this project, and SECURITY.md for more information about our security audits and bug bounty program. The goal of the project is to create and publish distributed applications that do not require third party trust. The network is operated by a decentralized group of nineteen Guardians who sign each transmitted message to attest to its authenticity. Now, audited and live, SOL and ERC 20 token holders can transfer their assets between ecosystems not just Solana and Ethereum. If the call is meant for a contract, check for code existence. More precisely, it is a token bridge and a NFT bridge. 03:42 UTC The team introduced safeguards for the Solana-side Portal (token bridge) to blacklist the fraudulent Wormhole messages to prevent the attacker from stealing additional funds. To prevent further exploits, Wormhole node operators temporarily stopped relaying messages from on-chain contracts, then upgraded the contract to fix the vulnerability. these guys are not "smart" engineers if they are letting this happen. The issue in the exploitable version was that the verify_signatures function did not assert that the user provided account was the special instruction sysvar. It is common practice in DeFi and infrastructure projects to get multiple audits for high tvl or critical dapps. See Live Contracts for current testnet and mainnet deployments of The first approach would upgrade the contract using the in-protocol governance mechanism. This new Wormhole bridge has a vast amount of flexibility in the Web 3 space. If you find it, please, contact us to [emailprotected] (include the name of the bridge in the subject line of your e-mail), Bridge token wasn't found. 13:08 UTC Jump Crypto replenished the contract with 120k ETH, restoring full collateral. Connect your target chain wallet by clicking Connect. If you have any information, please, contact us [emailprotected]. Thanks for your patience. In addition, a smart contract (or program on Solana) manage each token on each chain.
Someone hired to look for security holes or back doors might find one, say nothing, then exploit it. Jump Crypto has recapitalized the contract to ensure that all Wormhole-wrapped Ether on every chain is fully backed. Basically, the wormhole program obtains the set of signatures from the prior instruction via the instruction sysvar program (in which its address is inputted by the user). The check that Secp256k1 was called previously passed (even though it was in a completely different context), so the signatures were believed to have been properly verified. Users can specify arbitrary input accounts when calling a function on Solana. Wormhole is targeting chains that do not have light clients or chains that otherwise could be IBC compatible it is designed to connect to a number of high-value chains focused on decentralized finance.
implied. Our analysis tried to summarize and give a bit of context of the previous analysis reported during the first hours of the hack: Post written by: Tuyet Duong and Sylvain Pelissier. Hopefully audits will be a standard for any future bridge solutions. This is a growing and worrying trend (given other recent high profile hacks).
