Employees at financial services firms hit with an email attack campaign abusing a Google Cloud storage service.
A malicious email campaign has been found abusing a Google Cloud Storage service to host a payload sent to employees of financial services organizations, Menlo Labs researchers report.
The threat appears to have been active in the US and UK since August 2018. Victims receive emails containing links to archive files; researchers say all instances in this particular campaign have been .zip or .gz files. All cases involve a payload hosted on storage.googleapis.com, which appears to be related to Google’s cloud storage service but is, in fact, a malicious link.
