  • The Qilin ransomware group claimed responsibility for a cyberattack on Yanfeng Automotive Interiors by sharing screenshots of stolen details, including financial documents, non-disclosure agreements, quotation files, and internal reports. Earlier this month, it was reported that Yanfeng was impacted by a cyberattack that directly affected Stellantis, forcing the car company to stop production at its North American plants.

  • Egyptian e-payment provider Fawry suffered an attack by LockBit 3.0 ransomware that successfully encrypted files and also resulted in data exfiltration. While the firm confirmed that no financial data was stolen in the attack, it revealed that personal details like addresses, phone numbers, and dates of birth were among the stolen data.

  • International logistics giant DP World confirmed that the cyberattack earlier this month disrupted its operations in Australia. However, no ransomware payloads or encryption was used in the attack. The disruption had left over 30,000 containers stranded and available storage spaces were filled.

  • The Daixin Team ransomware group claimed responsibility for hacking the North Texas Municipal Water District (NTMWD) and threatened to leak sensitive data.
