According to iThome, e-commerce cloud ERP provider Mallbic stated that routine daily security checks on October 31 uncovered host anomalies and confirmed that unauthorized malicious commands had been executed on certain hosts; attackers entered through a brand website service portal, potentially affecting consumer and transaction data imported by merchants from other e-commerce platforms [1]. The report noted that Shopline announced on November 3 that it had rotated relevant API integration keys while stating that the Shopline platform itself was not breached [1]. We have not yet obtained the original official notices from Mallbic or Shopline. Merchants using Mallbic services should contact the vendor to confirm whether their order data falls within the affected scope [1].

Timeline
Technical details
What Happened
According to Mallbic's statement, anomalous host logs were discovered during daily security checks on October 31, prompting early-morning incident response that confirmed unauthorized execution of malicious commands on certain hosts; the primary entry point was patched on the afternoon of October 30 and reported to competent authorities [1]. Brands using its services, including "Gogo Energy" and "BeRule", stated that written notices from the vendor indicated their databases had been queried and subjected to attempted [1].
Scope of Impact
Attackers entered the system via a brand website service portal, meaning potentially affected data is not limited to brand websites and also includes consumer and transaction records imported by merchants from other e-commerce platforms; the exact data fields and merchant scope remain under investigation [1]. Shopline stated that it has no direct contractual relationship with third-party ERP vendors chosen by merchants and only provides API connectivity, adding that while its own platform was not compromised, it has proactively rotated the relevant API keys [1].
Our analysis
The following is our opinion, not a sourced statement.
Following the 91APP incident, the attack surface has expanded from storefront platforms to third-party ERP systems selected by merchants. Merchants should inventory all third-party tools that read order data via APIs, verify contractual incident notification obligations, and ensure they can rapidly revoke API tokens when a vendor breach occurs.
Remediation
Vendor guidance
- 1Merchants should verify whether they use Mallbic order or fulfillment management services detect[1]
Request formal investigation findings and the affected order date range from Mallbic.
Our addition
- 1Revoke and reissue API tokens for third-party tools mitigate[1]
Include API integration keys authorized for ERP systems across storefront platforms and other e-commerce marketplaces.
