近几日观察到从中国移动网内进来的DDOS攻击强度大大超过电信和联通,峰值高达600Gbps,均为TCP攻击。看到有人反映香港各机房的CMI大网出国方向不太稳定,有可能是由于这种高强度的攻击影响大网导致。

绝大部分攻击流量从以下网段发出
183.249.66.0/24
183.248.220.0/24
120.240.101.0/24

183.232.202.0/24


以下为部分攻击IP sample,由于很多.0 .1 的IP,相信是由/24内设备伪造发出,大概率是租用了中国移动带宽发包(其中广东移动为重灾区),但由于机房URPF配置不够严格,所以还能伪造同个网段的IP。
此前曾经向中移动国际公司反映过,但国际公司表示因为是国内发出,他们无法直接处理, 只能向中移动集团反映。

Telegram announces Anonymous Admins

The cloud-based messaging platform is also adding Anonymous Group Admins feature. As per Telegram, this feature is being introduced for safer protests. As per the Telegram blog post, users can “Toggle Remain Anonymous in Admin rights to enable Batman mode. The anonymized admin will be hidden in the list of group members, and their messages in the chat will be signed with the group name, similar to channel posts.”

In many cases, the content resembled that of the marketplaces found on the dark web, a group of hidden websites that are popular among hackers and accessed using specific anonymising software.“We have recently been witnessing a 100 per cent-plus rise in Telegram usage by cybercriminals,” said Tal Samra, cyber threat analyst at Cyberint.The rise in nefarious activity comes as users flocked to the encrypted chat app earlier this year after changes to the privacy policy of Facebook-owned rival WhatsApp prompted many to seek out alternatives.telegram from us
