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.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
According to reports, the messages that were circulating among the users of the ISP had the following subjects:
"DHL PROMO FREE!!! (fwd)"
Descriptions of the SubSeven and Barok trojans can be found on our virus information pages:
