A recent cybersecurity breach has exposed vulnerabilities in government agencies, as hackers infiltrated the U.S. Agency for International Development (USAID) to mine cryptocurrency. The attackers secretly exploited the agency’s Microsoft Azure cloud resources, leading to $500,000 in unauthorized service charges before the breach was detected. This incident highlights the growing threat of cryptojacking, a cybercrime where hackers hijack computing power for financial gain.
How the Hackers Gained Access
The attackers used a technique called password spraying, which involves trying a set of commonly used passwords on multiple accounts until one works. They managed to breach a high-level administrator account that was part of a test environment, gaining significant control over the system.
Once inside, they created another account with similar privileges, allowing them to operate undetected for some time. Both accounts were then used to run cryptomining software, which consumes large amounts of processing power to generate digital currency. Since USAID was responsible for cloud costs, the agency unknowingly footed a massive bill for unauthorized usage.
What is Cryptojacking?
Cryptojacking is a cyberattack where hackers steal computing resources to mine cryptocurrencies like Bitcoin or Monero. Mining requires powerful hardware and electricity, making it expensive for individuals. By infiltrating cloud systems, cybercriminals shift these costs onto their victims, while reaping financial rewards for themselves.
This attack is part of a larger trend:
1. 2018: A cryptojacking incident compromised government websites in the U.S., U.K., and Ireland through a malicious web plugin.
2. 2019: Hackers accessed an AWS cloud account of a U.S. federal agency by exploiting credentials leaked on GitHub.
3. 2022: Iranian-linked hackers were found mining cryptocurrency on a U.S. civilian government network.
Cybersecurity experts warn that cryptojacking often goes unnoticed because it doesn’t immediately disrupt services. Instead, it slowly drains computing resources, resulting in skyrocketing cloud costs and potential security risks.
How USAID Responded
Once the attack was discovered, USAID took steps to secure its systems and prevent future breaches:
A USAID internal report emphasized the need for stronger cybersecurity defenses to prevent similar incidents in the future.
Experts Warn of Increasing Cryptojacking Threats
Cryptojacking attacks are typically carried out by individual hackers or cybercrime syndicates looking for quick profits. However, some state-sponsored groups, including those linked to North Korea, have also used this method to fund their operations.
Cybersecurity professionals explain how these attacks work:
“If I break into someone’s cloud system, I can mine cryptocurrency using their resources, while they get stuck with the bill,” — Hamish Eisler, Chainalysis.
Jon Clay, a Threat Intelligence Expert at Trend Micro, describes cryptojacking as a persistent issue, where cybercriminals constantly look for new ways to exploit vulnerabilities.
How to Protect Against Cryptojacking
Organizations can take several measures to reduce the risk of cryptojacking attacks:
To combat these threats, Microsoft introduced mandatory MFA for Azure logins, which began rolling out in 2024. This security measure is expected to make it harder for hackers to take over cloud accounts.
Cryptojacking is a growing cybersecurity threat that can lead to financial losses, operational disruption, and security risks. The USAID breach serves as a wake-up call for both government agencies and businesses to strengthen their cyber defenses. Without proactive measures, organizations remain vulnerable to attacks that silently drain resources and increase costs.
There is no denying that Solana, one of the fastest-growing blockchain networks, has introduced a groundbreaking security feature called the Winternitz Vault. This feature will protect digital assets from quantum computing threats while maintaining the platform's high performance. Solana intends to address the challenges posed by quantum computing proactively to safeguard its users' funds and ensure the longevity of its blockchain infrastructure.
With the help of a decades-old cryptographic technique, Solana has developed a quantum-resistant vault that uses this technique to protect users' funds from quantum computer attacks. As part of the solution, known as the Solana Winternitz Vault, new keys are generated for every transaction as part of a hash-based signature system.
The company introduced a system called the "Solana Winternitz Vault" that protects user funds from quantum threats. The vault utilises a hash-based signature system that generates new keys for every transaction, making it highly secure. The chief scientist at Zeus Network, Dean Little, who is also a cryptography researcher, elaborated in a GitHub post that this approach complicates quantum computing and makes it harder for quantum computers to orchestrate coordinated attacks on public keys that are exposed during transactions, diminishing their ability to execute coordinated attacks. Since the vault exists in the current version as an optional feature, rather than as part of the network security upgrade, no fork is in sight.
As a result, users will need to actively store their funds in Winternitz Vaults instead of regular Solana Wallets if they wish to ensure that their funds remain quantum-proof. Even though the quantum-resistant vault is an optional feature rather than a system-wide requirement, it is important to note that it is still an optional feature. For this enhanced security to be realised, users need to choose to store their funds in the Winternitz Vault rather than the standard Solana wallet.
The vault's operation includes creating a split-and-refund account system to ensure secure fund transfers while protecting residual balances. The Winternitz Vault, a quantum-resistant solution developed by Solana developers, has been implemented to counter this risk and is based on a cryptographic technique dating back decades.
As a result of the vault's hash-based signature system, which generates new keys with each transaction, quantum computers are less likely to be able to crack the cryptographic keys because the vault employs a hash-based signature system. Using the Winternitz One-Time Signatures protocol, this vault creates 32 private key scalars that are hashed 256 times. It does not store the entire public key but only its hash for verification purposes.
It is important to note that every time a transaction is carried out, the vault creates a new set of keys, so no hacker can predict or steal a key before it is used. Solana's Winternitz Vault sets a new benchmark for blockchain security in the face of quantum computing, allowing users to take advantage of the optional tools necessary to protect their digital assets against future threats.
By implementing this forward-looking strategy, Solana reinforces its commitment to innovation and security that it has always displayed, placing it as a market leader in the blockchain space as quantum computing continues to develop, providing blockchain networks like Solana the flexibility to adapt to new challenges as they arise. It is Solana's goal to stay abreast of such advancements, ensuring its users can be assured that their digital assets can be safeguarded with confidence, regardless of future technological advances.
Nonetheless, Cornell University researchers have found that breaking an elliptic curve cryptographic key with 160 bits would require approximately 1,000 qubits, which is far more than is currently available. The blockchain industry is still pushing forward despite this. In its beta stage, QAN, for example, claimed it had achieved "quantum hardness," and other protocols have quietly improved their cryptographic foundations.
In recent years, quantum computing power has been predicted to grow exponentially – a phenomenon known as Neven's Law – and some experts believe that this will happen in the future. This forecast has driven more blockchain developers to implement quantum-resistant solutions, even though full-scale quantum computers are still years or decades away from seriously threatening the current cryptographic standards for coins, tokens, and other applications. Considering quantum resistance as an extra feature for many crypto projects may seem overkill, but Web3 developers are known for always being two steps ahead of the game.

The Lazarus Group, infamous for high-profile cyberattacks, gained notoriety for hacking Sony Pictures in retaliation for the 2009 film The Interview, which mocked North Korean leader Kim Jong Un. Their recent activities, however, focus on cryptocurrency theft, leveraging advanced social engineering techniques and malicious code.
Social Engineering and the Ginco Incident
In late March 2024, a TraderTraitor operative posing as a recruiter contacted an employee of Ginco, a Japanese cryptocurrency wallet software company, via LinkedIn. Disguised as part of a pre-employment process, the operative sent a malicious Python script under the guise of a coding test. The employee unknowingly uploaded the script to their GitHub account, granting the attackers access to session cookie information and Ginco’s wallet management system.
The attackers intercepted legitimate transaction requests from DMM employees by maintaining this access. This led to the theft of over 4,500 bitcoins, valued at $308 million. The funds were traced to accounts managed by the TraderTraitor group, which utilized mixing and bridging services to obfuscate the stolen assets.
North Korea's Financial Strategy and Cryptocurrency Exploitation
With international sanctions severely restricting North Korea's access to global financial systems, the regime increasingly relies on cybercrime and cryptocurrency theft for revenue generation. Due to their decentralized and pseudonymous nature, cryptocurrency presents a lucrative target for laundering stolen funds and bypassing traditional banking systems.
Chainalysis Findings
Blockchain intelligence firm Chainalysis attributed the DMM Bitcoin hack to North Korean actors. The attackers exploited weaknesses in the platform's infrastructure to perform unauthorized withdrawals. The stolen cryptocurrency was routed through multiple intermediary addresses and processed via the Bitcoin CoinJoin mixing service to conceal its origins. Portions of the funds were further transferred through various bridge services before being channelled to HuiOne Guarantee, a website linked to the Cambodian conglomerate HuiOne Group, a known facilitator of cybercrime.
Additional Findings by AhnLab Security Intelligence Center
The AhnLab Security Intelligence Center (ASEC) has reported another North Korean threat actor, Andariel — part of the Lazarus Group — deploying a backdoor known as SmallTiger. This tool has been used in campaigns parallel to those executed by TraderTraitor, highlighting the group's continued evolution in cybercrime tactics.
The coordinated alert from international agencies underscores the urgent need for enhanced cybersecurity measures within the cryptocurrency industry to counter sophisticated threats like those posed by the Lazarus Group and its affiliates.
Chamath Palihapitiya, CEO of Social Capital, has raised alarms over Bitcoin’s future security, cautioning that its SHA-256 encryption may become vulnerable within the next two to five years. Speaking on the All-In Podcast, he highlighted rapid advancements in quantum computing, particularly Google’s unveiling of the Willow quantum chip featuring 105 qubits.

While acknowledging the infancy of quantum computing, Palihapitiya pointed to Google’s Willow chip as a pivotal development that could accelerate breakthroughs in cryptography. Despite scalability challenges, he remains optimistic that the cryptocurrency sector will evolve to develop quantum-resistant encryption methods.
Not all experts share his concerns, however. Ki Young Ju, founder of CryptoQuant, has expressed confidence that Bitcoin’s encryption is unlikely to face quantum threats within this decade.
Bitcoin’s pseudonymous creator, Satoshi Nakamoto, had anticipated such scenarios. In 2010, Satoshi proposed that the Bitcoin community could agree on the last valid blockchain snapshot and transition to a new cryptographic framework if SHA-256 were compromised. However, these early solutions are not without controversy.
Emin Gün Sirer, founder of Avalanche, has warned that some of Satoshi’s early-mined coins used an outdated Pay-To-Public-Key (P2PK) format, which exposes public keys and increases the risk of exploitation. Sirer suggested the Bitcoin community should consider freezing these coins or setting a sunset date for outdated transactions to mitigate risks.
Recent advancements in quantum computing, including Google’s Willow chip, briefly unsettled the cryptocurrency market.
