The South Korea-aligned cyberespionage group APT-C-60 has been leveraging a zero-day code execution vulnerability in the Windows version of WPS Office to install the SpyGlace backdoor on East Asian targets.
WPS Office is a productivity suite developed by the Chinese firm Kingsoft that is popular in Asia. Reportedly, it has over 500 million active users worldwide.
The zero-day flaw, tracked as CVE-2024-7262, has been leveraged in attacks in the wild since at least late February 2024, but impacts versions from 12.2.0.13110 (August 2023) to 12.1.0.16412 (March 2024).
Kingsoft "silently" patched the problem in March this year without informing the customers that the flaw was actively exploited, prompting ESET, who discovered the campaign and vulnerability, to publish a detailed report today.
In addition to CVE-2024-7262, ESET's investigation unveiled a second severe flaw, tracked as CVE-2024-7263, which Kingsoft patched in late May 2024 with version 12.2.0.17119.
