In a shocking turn of events last week, Mandiant’s X account, previously known as Twitter, fell victim to a sophisticated cyberattack attributed to a drainer-as-a-service (DaaS) group. The compromise, likely a result of a brute-force password attack, occurred on January 3, 2023, allowing the threat actor to seize control of the X account.
Drainers and Cryptocurrency Theft
The assailant exploited a change in X’s two-factor authentication (2FA) policy, bypassing the security measure. The attack involved the distribution of phishing links hosting a cryptocurrency drainer called CLINKSINK. These drainers execute malicious scripts, tricking victims into approving transactions and subsequently siphoning digital assets from their wallets.

The Proliferation of Drainer Attacks
Mandiant highlighted the concerning trend of increasing attacks on legitimate X accounts for cryptocurrency scams. Recent incidents, including the breach of the U.S. Securities and Exchange Commission (SEC) X account, underscore the severity of the situation. The SEC breach falsely claimed approval for the “listing and trading of spot bitcoin exchange-traded products,” briefly impacting bitcoin prices.
Enterprise Attack Surface Management Challenges
Shifting focus to cybersecurity challenges, experts acknowledged the constant expansion of the enterprise attack surface. The integration of new technologies and the digitization of businesses contribute to the complexity of managing potential vulnerabilities. Traditional approaches, such as acquiring new security tools for each emerging threat, prove unsustainable for large organizations.
Factors Contributing to Attack Surface Expansion
Several factors contribute to the widening attack surface, including the increased use of cloud services, remote working, the proliferation of IoT devices, vulnerabilities in supply chains, and the introduction of AI and machine learning technologies. Social networking platforms also expose organizations to risks through social engineering and business email compromise.
Embracing Innovative Solutions
Amidst these challenges, experts advocate for a shift towards prioritizing digital identities in cybersecurity. Identity and access management (IAM) and privileged access management (PAM) are proposed as effective strategies to strengthen access control and implement a sound zero-trust approach. Additionally, cyber insurance emerges as a crucial component in the cybersecurity arsenal, providing financial support in the aftermath of a breach.
Conclusion: Adapting to Evolving Threats
As cyber threats evolve, organizations must adopt innovative approaches to safeguard their digital assets. The traditional perimeter defense is no longer sufficient, and a comprehensive strategy involving identity protection, cybersecurity tools, and cyber insurance is essential. The key to deterring attacks lies in making unauthorized access expensive and prioritizing the security of digital identities in an ever-expanding cyber landscape.
