This week on Security Now! we have the return of "Clippy," Microsoft's much-loathed dancing paperclip; operation "ShadowHammer," which reports say compromised ASUS (but did it?); the ransomware attack on Norsk Hydro aluminum; the surprise renaming of Windows Defender; a severe bug revealed in the most popular PDF-generating PHP library; an early look at Microsoft's forthcoming Chromium-based web browser; hope for preventing caller ID spoofing; a needed update for users of PuTTY; Mozilla's decision to conditionally rely upon Windows' root store; Microsoft to offer virtual Windows 7 and 10 desktops through Azure; details of the Windows 7 End of Life warning dialog; then a bit of Sci-Fi, SQRL and SpinRite news, followed by our look at the results of the much anticipated Mid-March Vancouver Pwn2Own competition - one of the results of which our episode title gives away!
