XLink, an established Bitcoin blockchain bridge, is prepping a comeback after it shut down on May 15 after suffering a $10 million hack.
XLink was&nbsp;the victim of a security breach involving its Ethereum and BNB Smart Chain (BSC) endpoints.&nbsp;The XLink team first disclosed the breach in the early hours of May 15, which is now coming to a close on May 17 as the team prepares to resume normal operations.

The attacker exploited compromised private keys via a phishing scheme, which allowed them to control the BSC and Ethereum endpoints and withdraw around $4.3 million without authorization. However, according to XLink, a white hat hacker soon recovered the stolen assets.
Cointelegraph reached out to XLink for comment but didn't received a response by publication. “No endpoints other than BSC and Ethereum were affected by this exploit,” the company’s official statement said.

Despite the recovery on the BSC, approximately $5 million in mostly LunarCrush tokens remain locked on the Ethereum blockchain. However, the LunarCrush team is working closely with XLink to secure these funds — the majority of the $5 million has been “recovered or secured.”

 Another $5 million worth of funds are locked on Ethereum, mainly LunarCrush tokens. The @LunarCrush team, in close coordination with the XLink team, has implemented measures to secure those tokens.

According to XLink, residual crypto funds worth around $500,000 are still locked on Ethereum, but a majority of the funds have been either recovered or secured.

In response to the initial incident, the XLink team reacted quickly, temporarily suspending all operations on the bridge to conduct a thorough investigation. The investigation was carried out collaboratively with the team’s security partners — including Ancilia — and their Binance team liaisons.

XLink has insisted that all users who interacted with the compromised contracts should revoke any approved spending limits. The team issued detailed instructions, and links were <a href="https://x.com/XLinkbtc/status/1791313720619983097" target="_blank" rel="noopener nofollow">provided</a> for ETH and BSC users to mitigate further risk to funds:
<blockquote data-ct-non-breakable="true">
 “As we prepare to reopen XLink, it is urgent that Ethereum and BSC users check that their wallets have revoked access to the old compromised endpoint contracts. This step will assist in completely severing any connections with the compromised contract and mitigating any associated risks.”
</blockquote>
Users failing to do so remain at risk of losing their funds to the attacker.
<a href="https://cointelegraph.com/news/solana-memecoin-tool-pumpfun-claims-ex-employee-exploiter">Another exploit recently hit pump.fun</a>&nbsp;—&nbsp;a Solana memecoin creation tool — after it was claimed that a former employee took the firm for almost $2 million through a “bonding curve” attack. 
According to pump.fun, on May 16, the ex-employee took actions to compromise the protocol’s internal systems. The smart contracts have since been announced as “safe,” and victims of the incident will have “100% of [their] liquidity” restored.&nbsp;
