A malicious PDF file called report.pdf, debt.2007.pdf, overdraft.2007.10.26.pdf, or similar, has been massively spammed through e-mail. The PDF is spiced with exploit CVE-2007-5020 that downloads ms32.exe, which in turn downloads more components.
Massive spamming did not eventually lead to major problems, since the secondary download location was swiftly taken down preventing the downloader from functioning.
The subjects for the spam messages include:
Your credit report
Your credit points
Your balance report
Personal Financial Statement
