W32.Qakbot aka W32/Pinkslipbot or infostealer worm

W32.Qakbot aka W32/Pinkslipbot

W32.Qakbot in Detail by Symantec Nicolas Falliere

W32.Qakbot is a worm that has been seen spreading through network shares, removable drives, and infected webpages, and infecting computers since mid-2009. Its primary purpose is to steal online banking account information from compromised computers. The malware controllers use the stolen information to access client accounts within various financial service websites with the intent of moving currency to accounts from which they can withdraw funds. It employs a classic keylogger, but is unique in that it also steals active session authentication tokens and then piggy backs on the existing online banking sessions. It then quickly uses that information for malicious purposes.

The following screenshot is from the paper you see above

May 2 MAC Defender + May 11 Mac Protector Fake Antivirus Programs

MAC Defender Fake Antivirus Program

INTEGO SECURITY MEMO – May 2, 2011 MAC Defender Fake Antivirus Program Targets Mac Users

Quote from Intego: Description: Intego has discovered a fake antivirus program called MAC Defender, which targets Mac users via SEO poisoning attacks (web sites set up to take advantage of search engine optimization tricks to get malicious sites to appear at the top of search results).
When a user clicks on certain links after performing a search on a search engine such as Google, they are sent to a web site that displays a fake Windows screen with an animated image showing a malware scan; a window then tells the user that their computer is infected. After this, JavaScript on the page automatically downloads a file. The file downloaded is a compressed ZIP archive, which, if a specific option in a web browser is checked (“Open ‘safe’ files after downloading” in Safari, for example), will open. The file is decompressed, and the installer it contains launches presenting a user with the following screen:
