The main vulnerability in adobe which I don't use is using javascript to call on an insecure undocumented API it run shellcode.
I used origami to decrypt and decomporess and pdfid to check if it has javascript triggers which it doesn't I don't use foxit or adobe. I use an obscure reader. Recently, it crashed when i opened a pdf file. Can this be a malware attack? How do I check? Note about the edit - most modern Linux systems have several native PDF viewers available including a ancient version of Adobe Reader, usually you don;t need to bother with that - I suggest using Okular, and most versions of evince and mupdf work great as well , you don't need to use a Windows VM FirstNameLastName be weary of using lesser known products to avoid infection.
Hardened VM really is the only way to be sure. Add a comment. B-Con B-Con 1, 12 12 silver badges 19 19 bronze badges. I don't want to give the information in the PDF to google but thanks. Using Google Docs is good advice, but "Put it through a PDF viewer that isn't vulnerable to the exploit" sounds strange to my ears. Usually, you don't know whether a particular viewer is vulnerable until it's too late.
DmitryGrigoryev if the exploit depends on javascript as almost all of them do, then a viewer that does not support javascript makes that exploit impossible. An exploit that depends on file attachments is rendered impossible by a viewer that doesn't support attachments. An exploit that depends on retrieving data from a URL cannot work if the viewer does not support retrieving data from a URL.
And so forth. DmitryGrigoryev I'm not sure what your point is. An exploit specifically targeted to work with Sumatra is possible, as I stated in my answer.
Its likelihood is exceedingly small. No such method exists. Show 3 more comments. It should be quite tricky for a malware to get out of this.

Paging through the file looking for JS and calls to outside resources is quite effective if a bit slow. You shouldn't rely on strings for security: lcamtuf. What makes you think Sumatra is safer than any of the other PDF viewers out there? DmitryGrigoryev My reasons for thinking this are clearly stated in my answer. I recommend re-reading the first paragraph and looking at the link in the second paragraph.
You will find your answers there. Overrides : This filter takes information that appears on the mail's details tab and uses it to expose where organizational, or user policies, for allowing and blocking mails have been overridden.
The most important thing about this filter is that it helps your organization's security team see how many suspicious emails were delivered due to configuration. This gives them an opportunity to modify allows and blocks as needed.
This result set of this filter can be exported to spreadsheet. Email timeline view : Your security operations team might need to deep-dive into email details to investigate further. The email timeline allows admins to view actions taken on an email from delivery to post-delivery. To view an email timeline, click on the subject of an email message, and then click Email timeline.
It appears among other headings on the panel like Summary or Details. These results can be exported to spreadsheet. Email timeline will open to a table that shows all delivery and post-delivery events for the email. If there are no further actions on the email, you should see a single event for the original delivery that states a result, such as Blocked , with a verdict like Phish.
Admins can export the entire email timeline, including all details on the tab and email such as, Subject, Sender, Recipient, Network, and Message ID.
The email timeline cuts down on randomization because there is less time spent checking different locations to try to understand events that happened since the email arrived. When multiple events happen at, or close to, the same time on an email, those events show up in a timeline view. Your security operations team can either:. Check the delivery action and location. View the timeline of your email. This results in a more complete picture of where your email messages land.
Part of the goal of this change is to make investigations easier for security operations teams, but the net result is knowing the location of problem email messages at a glance. Delivery location shows the results of policies and detections that run post-delivery.
It's linked to a Delivery Action. This field was added to give insight into the action taken when a problem mail is found. Here are the possible values of delivery location:. Email Timeline is a field in Threat Explorer that makes hunting easier for your security operations team. When multiple events happen at or close to the same time on an email, those events show up in a timeline view. Some events that happen post-delivery to email are captured in the Special actions column.
Combining information from the timeline of an email message with any special actions that were taken post-delivery gives admins insight into policies and threat handling such as where the mail was routed, and, in some cases, what the final assessment was.
