fevereiro 27, 2019
0x00 Overview
PowerShell has been a focus of concern for network defense. The fileless PowerShell, featuring LotL and excellent ease of use, is widely used in various attack scenarios. In order to capture PowerShell-based attacks, an increasing number of security professionals tend to, through PowerShell event log analysis, extract attack records such as post-exploitation data for enterprise security monitoring, alerting, trackback, and forensics.

ADB.Mirai: New Mirai Botnet Variant Spreading via the ADB Debug Port
![](https://nsfocusglobal.com/wp-content/uploads/2019/02/1108-2.jpg)
fevereiro 26, 2019
Overview
At the beginning of 2019, the domestic and overseas security vendors have detected cryptominers that spread via Android devices with an open ADB debug port. Recently, NSFOCUS Fu Ying Labs has detected once more such botnets that can be used to launch distributed denial-of-service (DDoS) attacks. The sample analysis suggests that this botnet family (named Darks) is another variant of the Mirai botnet, whose scanning behavior is highly similar to the mining sample discovered in early 2019. The mining sample is created for the mining purpose, while this sample is intended for DDoS. We suspect that the emergence of this sample possibly has something to do with the depression of the virtual currency industry. (mais…)
