Summary

Since September 5th, there has been information in the media about a trojan called Donald Duck, which is said to spread with a variant of the Love Letter worm. F-Secure is not aware of such a variant of Love Letter. Instead, there has been a hacker attack against an ISP in the Philippines, where the hackers were spreading two known trojans called "donald.exe" and "erap.exe" as e-mail attachments. These files are detected by F-Secure Anti-Virus as SubSeven.backdoor.v213 and Trojan.PSW.Barok.c.

Additional Details

According to reports, the messages that were circulating among the users of the ISP had the following subjects:

        "DHL PROMO FREE!!! (fwd)"

and

        "erap Estrada".
