乌克兰总统泽连斯基21日称，乌克兰的反攻进展慢于预期。俄军在前线领土上布设了20万平方公里的地雷，因此乌军的军事推进很困难。但泽连斯基称，不会因此被迫加快脚步。泽连斯基在另一个讲话中表示，乌军在南部前线推进并坚守东部防线。俄罗斯总统普京也表示，俄罗斯观察到乌克兰反攻陷入停滞，虽然乌克兰仍具有一定的进攻潜力，但它明白自己没有机会。
乌克兰东半部22日凌晨响起空袭警报。在克里维里赫和克列缅丘格以及哈尔科夫等地区发生爆炸。尚无袭击或伤亡报告。俄罗斯21日表示，击落了抵达莫斯科周边地区的无人机。
目前乌军尚未反攻俄罗斯的主要防线。不过据信乌克兰拨出的12个旅中的大部分也尚未参战。

The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.
Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
