A second ransomware group recently claimed to have breached Change Healthcare's defenses, but the company has seen no evidence of this. The attack on UnitedHealth highlights the vulnerabilities of the connected economy, with cybercriminals increasingly using artificial intelligence methods to bypass security measures. UnitedHealth has provided over $6 billion in funding and interest-free loans to help care providers affected by the breach.
Key takeaways:
- Change Healthcare, owned by UnitedHealth, has fixed an issue that hindered medical claims processing for some customers.
- The company suffered a massive hack in February that disrupted hospitals and pharmacies around the country, costing UnitedHealth $872 million.
- The breach was caused by a ransomware gang known as ALPHV or BlackCat, and another ransomware group claims to have breached Change Healthcare's defenses.
- Cybercriminals are now using artificial intelligence methods to combine legitimate and fraudulent data to bypass security measures like know-your-customer (KYC) and anti-money laundering (AML) authentication.
