כל אתר ישראלי שמטמיע סקריפט של nagich "נפרץ" ומציע את ההודעה הבאה. ללמדכם לקח כמה הטמעת סקריפטים צד-שלישי זה מפגע תברואתי. נעםר וברזיק צדקו. pic.twitter.com/DKk7BeDHkx

The way Third Party Plugin Abused by Hackers
Since the nagich accessibility Plugin contains a severe vulnerability let hackers to replace the malicious code with an embedded link.
It was successfully achieved by taking control of a record on a DNS server of the nagich service domain name that allows attackers to redirect traffic to a server that it controls rather than to the original server.
Ran Bar-Zik Programmer and a security researcher wrote in “Internet israel” who wanted to reach the nagich.co.il domain name where the accessibility script was located were redirected to the IP address ][18.104.22.168] instead of the correct IP address of the server: [22.214.171.124].”
The nagich site is not just a website. Is a site that provides an accessibility plugin. An accessibility plugin is a small Java script that runs on a site that chooses to use this service and gives it all kinds of options.
Once we gave permission to other functions then it has an ability to run code on our site means that, it can do anything with our site.
As soon as the attackers diverted the traffic from the legitimate server to their illegitimate server, they injected malicious code that made defacement, that’s all. Researcher said.
