مرکز مدیریت امداد و هماهنگی عملیات رخدادهای رایانه ای نسبت به حملات سایبری به سرویس دهنده‌های ایمیل سازمانی در سطح کشور هشدار داد.



نسیم توسعه به نقل از مهر:   مرکز مدیریت امداد و هماهنگی عملیات رخدادهای رایانه ای نسبت به حملات سایبری به سرویس دهنده‌های ایمیل سازمانی در سطح کشور هشدار داد.

 مرکز ماهر با اعلام گزارشی فوری در خصوص شناسایی حملات سایبری به سرویس دهنده های ایمیل سازمانی در کشور هشدار داد.

این مرکز اعلام کرد: پیرو گزارشات واصله از سطح کشور،‌ حملات به سمت سرویس دهنده‌های ‫ایمیل سازمانی افزایش شدیدی داشته است. این حملات در قالب brute force روی رمز عبور از طریق پروتکل‌های imap و pop۳ و نیز حمله DOS‌ از طریق ارسال دستورات پی‌درپی imap و pop۳ صورت می‌گیرد.

حملات فوق الذکر عمدتا از بلوک IP آدرس‌های زیر رصد شده است:

۹۲.۶۳.۱۹۳.۰/۲۴
۵.۱۸۸.۹.۰/۲۴

مرکز ماهر اکیداً توصیه کرده که مدیران سیستم نسبت به بررسی وضعیت امنیتی سرورهای ایمیل خود و اجبار کاربران در انتخاب رمزهای عبور مناسب و پیچیده اقدام کنند.

همچنین لازم است سیاست مسدودسازی حساب کاربری در صورت چندین بار تلاش با رمز عبور موفق (account lockout) فعال باشد.

لازم است مدیران سیستم های سازمانی، ضمن نظارت بر رویدادنماهای ثبت شده در سرور ایمیل، در صورت مواجهه با اختلالات مشابه موضوع را به اطلاع مرکز ماهر برسانند.
