I have for the purpose of disabling and enabling WSH two tiny. In fact, I disabled Windows Script Host on my laptop, and so far I didn’t have the need to re-enable it for a legitimate script to run. In my view, all obfuscated scripts should be blocked by all the major security vendors, until a reliable way of signing such scripts is developed.

The Chinese Qihoo 360 Total Security has been criticized in the past for the heuristic of its own QVM II engine had the tendency to block almost all the obfuscated scripts and macros. So the 0-day protection can only be obtained by blocking everything?!

Should I unblock the attachment and unzip the script, in most cases I’d notice that the respective ransomware variant is not yet recognized, but it will become so in the next 48 h. The funny thing is that either of Kaspersky and ESET (and any of their security solutions, even the “simple” antivirus product) would block such a zipped script, but not because they recognize its malevolence: it’s just a general policy of not allowing such attachments. There are days when I receive e-mails with zipped 0-day ransomware scripts even more than once a day–but there are also days of total silence. This being said, signature-based malware detection is futile. Obfuscated JavaScript code can be seen everywhere. And yes, obfuscated files are accepted: Microsoft even created an obfuscation tool for VBScript, but not an unobfuscation counterpart.

Windows is designed to execute Windows Scripting Hosts scripts written in no matter what language, including VBScript (.vbs/.vbe) and JScript (.js/.jse), or whatever a.

Windows is designed to execute stupid Office macros that can “do things” not to the document itelf, but to the system.

Windows is designed to allow the execution of binaries from paths such as %temp%, %AppData%, %LocalAppData%, %userprofile%, %programdata%, %allusersprofile%, and everywhere else.

Most malware infections can be mitigated, but ransomware is a different kind of beast.Īnd the way Microsoft has designed its fucked-up operating system, ransomware is merely a disaster waiting to happen: Truth be told, I never really got infected but, should an infection with a ransomware happen, this might prove catastrophic, given that sometimes it takes me months before I make backup copies of everything that’s valuable. With the ransomware epidemic of 2015-2016, this necessity is even more obvious. This is because all of them suck, yet I need protection.

It happens to me more than once a year to change the antivirus-cum-antimalware solution.
