Jack of all trades

Among this array of threats we found a rather interesting sample – Trojan.AndroidOS.Loapi.

This Trojan boasts a complicated modular architecture that means it can conduct a variety of malicious activities: mine cryptocurrencies, annoy users with constant ads, launch DDoS attacks from the affected device and much more.
4A vulnerability in the TCP stack of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper processing of certain TCP packets in the closing sequence ...

Wi-Fi Protected Access(WPA,more commonly WPA2)handshake traffic can be manipulated to induce nonce and session key reuse,resulting in key reinstallation by a wireless access point(AP)or client.

An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used.

Attacks may include arbitrary packet decryption and injection,TCP connection hijacking,HTTP content injection,or the replay of unicast and group-addressed frames.

These vulnerabilities are referred to as Key Reinstallation Attacks orKRACKattacks.
