A new round of spam, first noticed on January 8th, has been observed by anti-phishing researchers at the University of Alabama at Birmingham. In many ways the spam is typical phishing emails, trying to trick users into visiting a fraudulent website. This family of emails uses the domains listed below to host several different phishing campaigns, each in a different subdirectory. For example:
/_mem_bin/formslogin.asp = Intelligent Finance
/default.aspx = NatWest Bank
/confirm.asp = Royal Bank of Scotland
But in addition to the traditional phishing, or bank fraud websites, which try to steal userids and passwords for online banking accounts, this spam campaign also includes a fake Internal Revenue Service website - and it isn't asking for your password!
/importantpubs/index.htm = Internal Revenue Service
After giving a warning to "Business/Corporate Treasury Managers and Accountants", the fraudulent IRS website claims to have "important recent changes to business and corporate tax laws".
Each of the links which claim to be a new document with important tax information actually is a link to a virus! With file names like:
ALL_TAXPAYERS_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
ESTATE_AND_TRUST_TREASURY-MANAGERS_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
EXCISE_TREASURY-MANAGERS_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
EXEMPT_ORG_TREASURY-MANAGERS_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
FOREIGN_ISSUES_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
INDIVIDUALS_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
IRA_TREASURY-MANAGERS_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
TREASURY-MANAGERS_IRS_IMPORTANT_NOTICE_SELF-PDF.EXE
the virus attempts to trick users into opening the file. If successful, the user will think he is getting information to share his taxes with the IRS, but actually the user will begin to share their information with criminals instead!
