Появилась новость о новой вредоносной компании направленной на Kubernetes от небезызвестной группы TeamTNT. Начальный доступ получается через неправильную конфигурацию kubelet, позволяющую анонимный доступ. Так злоумышленники через kubelet API попадают в первый контейнер, который находится под управлением найденного kubelet и загружают туда вспомогательные инструменты. Далее уже вредоносный код (Hildegard) пытается как можно в большем количестве найти контейнеров в кластере и запустить через kubelet API в них майнеры.

По оценке исследователей безопасности данная атака еще не имеет широкого распространения и находится только в стадии разработки/подготовки. Из интересного, вредоносный код несет с собой два OpenSource инструмента для поднятия привилегий и побега из контейнера: Peirates и BOtB.

По моей оценке:
1) Если у вас kubelet торчит в интернет, то это game over.
2) Если вы видите и знаете, что у вас происходит внутри контейнеров, то такое поведение нельзя не заметить.

Telegram Desktop App Not Working on Windows?

Preliminary Fixes.

Rule out internet issues: Make sure your device is connected to a stable internet connection by running other apps on the same computer. When other apps work fine, connectivity issues get ruled out. Check Telegram status: When the internet is connected correctly, the next step should be to check that Telegram isn't experiencing downtime. To do that, visit the downdetector website and type in "Telegram" to see what's happening. When Telegram's status is active and there are no reported issues on downdetector, Telegram's backend is unlikely to present any issues.Give Telegram a fresh start: After ruling out internet and backend issues, give Telegram a fresh start to remove the possibility of temporary glitches that prevent you from contacting your friends. Shut down the Telegram app completely, preferably from Task Manager, and then relaunch it.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences.
