Google researchers observed two separate waves of attacks that took place in February and October 2020, respectively. Threat actors set up malicious sites in a series of watering hole attacks that were redirecting visitors to exploit servers hosting exploit chains for Android, Windows, and iOS devices.
“In October 2020, Google Project Zero discovered seven 0-day exploits being actively used in-the-wild. These exploits were delivered via “watering hole” attacks in a handful of websites pointing to two exploit servers that hosted exploit chains for Android, Windows, and iOS devices.” wrote the popular Project Zero researcher Maddie Stone. “These attacks appear to be the next iteration of the campaign discovered in February 2020 and documented in this blog post series.”
