Security experts have reported that suspected North Korean hackers have compromised a widely-used software package, Axios, in a significant supply-chain attack. For three hours on Tuesday, the hackers accessed the account of a software developer managing Axios, which is utilized by thousands of US companies across various sectors, including health care and finance. During this time, they sent out malicious updates, prompting a nationwide response to assess the damage. Cybersecurity firm Mandiant indicated that the hackers are likely to leverage their access to target cryptocurrency firms, potentially funding North Korea's nuclear ambitions. This incident is part of a broader trend of North Korean cyberattacks, which have previously resulted in the theft of billions of dollars from financial institutions. Experts warn that the full impact of this attack may not be known for months, with initial findings revealing at least 135 compromised devices across 12 companies. The attack underscores the vulnerabilities in software supply chains, especially as organizations increasingly adopt AI technologies without adequate oversight.
