Issue description

Steps to reproduce: (28 November 2020)
OS Windows 10 Pro, latest version;
Microsoft Edge, latest version.
F-Secure anti-virus, fully up-to-date:

Downloaded zip file of processing/docs (28 November 2020).
Scanned with up-to-date F-Secure anti-virus.
3 instances of the blackhole exploit found:

Exploit.EXP/Blacole.S.9

Category: Malware
Type: Exploit
Platform: Java

3 specific harmful items found (from the F-Secure report):

Exploit.EXP/Blacole.S.9
processing-docs-master.zip[5754] processing-docs-master/exhibition/works/cdrawer/cdrawer.jar[2] BApplet.class
processing-docs-master.zip[5909] processing-docs-master/exhibition/works/inequality/inequality.jar[2] BApplet.class

Part of an exploit kit: see also:

F-Secure reported that it was unable to clean the files. I reverted to deleting the zip file.

See above note.

Proposed fix

Author to examine original code files, perhaps send individual files to F-Secure for analysis; remove exploit from affected files if the exploit is real, or modify the code to prevent false negative if that's the case, or post notice that such a false negative exists and can be safely ignored.

I would have sent the zip file to F-Secure for analysis myself, but their file-size limit is 30Mb. I'm not opening the zip file myself just in case this is a real issue.

Bắt đầu với ba đường dẫn đã được báo cáo trong kho lưu trữ tài liệu: exhibition/works/cdrawer/cdrawer.jar, inequality/inequality.jar và sodaprocessing/sodaprocessing.jar, tập trung vào từng BApplet.class. So sánh các tệp này với mã nguồn gốc của chúng và gửi từng tệp riêng lẻ cho F-Secure để phân tích nếu có thể. Công việc được xem là hoàn tất khi xác nhận các phát hiện là thực hay dương tính giả, sau đó loại bỏ exploit hoặc ghi lại phản hồi an toàn đối với trường hợp dương tính giả.
