Hacked X Accounts Promote Fake Memecoin in Coordinated Social Engineering Attack

On September 18, 2024, a wave of high-profile account compromises on X (formerly Twitter) demonstrated the persistent threat that social engineering poses to the cryptocurrency community. Multiple well-known accounts, including those of Lenovo India and Yahoo News UK, were hijacked to promote a fraudulent memecoin called HACKED, exposing critical vulnerabilities in how social media platforms secure high-reach accounts.

Blockchain investigator ZachXBT was among the first to flag the coordinated attack, alerting the community that several large accounts had been compromised and were actively posting links to the fake token. Despite the significant reach of these accounts — collectively followed by millions of users — the scammers managed to extract only approximately $8,000 worth of cryptocurrency before the scheme was identified and publicized.

The Exploit Mechanics

The attack followed a familiar pattern that has plagued the crypto community for years. The threat actors gained unauthorized access to verified corporate and media accounts, likely through compromised third-party application permissions. Once inside, they posted promotional content for the HACKED token across multiple high-profile feeds simultaneously, creating an artificial sense of legitimacy through the sheer volume of trusted sources appearing to endorse the coin.

ZachXBT noted that the compromised accounts likely all granted permissions to the same malicious third-party application or website. This is a common attack vector where users authorize a seemingly legitimate app to access their X account, inadvertently giving attackers the ability to post on their behalf. The mechanism is deceptively simple: users click through OAuth prompts without carefully reviewing what permissions they are granting.

The HACKED token itself was designed to capitalize on the spectacle of account hacks, creating a twisted meta-narrative where the hack became the marketing. At its peak, the token reached a market capitalization of approximately $67,000 before collapsing as the community raised alarms.

Affected Systems

The primary targets were high-follower corporate and media accounts on X. Lenovo India, with its substantial technology-focused following, and Yahoo News UK, with its broad mainstream audience, represented ideal distribution channels for the scam. By leveraging established media brands, the attackers bypassed the initial trust barrier that typically protects users from unknown token promotions.

This incident is part of a broader pattern of social media account compromises in the crypto space. Just weeks earlier, French football star Kylian Mbappé’s account had been similarly hijacked to promote a fictional cryptocurrency. The recurring nature of these attacks highlights systemic weaknesses in how social media platforms handle account security, particularly for accounts with large followings that could influence market behavior.

The Mitigation Strategy

For individual users, the primary defense against these scams is a combination of skepticism and proactive security hygiene. ZachXBT recommended that users regularly audit and revoke third-party application permissions on their social media accounts. Many users accumulate dozens of authorized applications over years of platform use, creating an ever-expanding attack surface.

Organizations should implement hardware-based two-factor authentication for all social media accounts, restrict access to a minimal number of authorized personnel, and maintain active monitoring for unauthorized posts. The use of dedicated social media management platforms with enhanced security controls, rather than granting direct account access to multiple team members, can significantly reduce the risk of credential compromise.

Platforms like X must also bear responsibility. Enhanced detection of mass simultaneous posts promoting the same token, particularly from previously unrelated accounts, could serve as an early warning system. Rate limiting promotional content from newly authorized applications would provide an additional layer of protection.

Lessons Learned

The HACKED memecoin incident reinforces several critical security principles. First, the credibility of a post is only as strong as the verification that the account holder actually authored it. Even verified accounts with blue checkmarks can be compromised. Second, the relatively small financial gain — just $8,000 from accounts with millions of combined followers — suggests that the crypto community is becoming more vigilant, though not immune. Third, third-party application permissions remain one of the most underappreciated attack vectors in social media security.

User Action Required

Users should immediately review and revoke unnecessary third-party app permissions on their X accounts through the platform’s security settings. Enable hardware-based two-factor authentication using a security key rather than SMS. Report any suspicious promotional content, even from verified accounts, and never invest in tokens promoted exclusively through social media posts without independent verification from multiple trusted sources. The crypto market cap stood at approximately $2.10 trillion on this date, with Bitcoin trading around $61,650 — a reminder that even in a mature market, social engineering remains the most effective attack vector.
