November 11, Securityweek – (International) Attackers abuse security products to install “Bookworm” trojan. Researchers from Palo Alto Networks discovered a new trojan dubbed “Bookworm” which captures keystrokes and steals the content of a clipboard, as well as load additional modules from its command and control (C&C) server to expand its abilities by using a Smart Installer Maker tool to disguise the malware as a self-extracting RAR archive, or a Flash slideshow/installer, to write a executable data definition language (DDL) file named “Loader.ddl,” and a file named “readme.txt,” to the victims’ system.

November 12, Securityweek – (International) “Cherry Picker” PoS malware cleans up after itself. Researchers from Trustwave discovered that a point-of-sale (PoS) malware dubbed “Cherry Picker” relies on a new memory scraping algorithm using a file infector for persistence that removes all traces of the infection from the system with updated versions of sr.exe and srf.exe, which has been used to install the malware and inject a data definition language (DLL) into processes. The latest version of the malware relies on an application programming interface (API) called “QueryWorkingSet” to scrape the memory and harvest the data. Source
