Security researchers have come across a new highly-destructive botnet that is capable of launching a variety of DDoS attacks such as UDP flood, SYN flood, ACK flood, GRE IP flood, and Value Source Engine specific flood. Dubbed Gucci, the botnet is targeting IoT devices in Europe.

The past 24 hours also saw multiple cybercriminals operations targeting English and Arabic-speaking users. The campaigns leverage OpenDocument Text (ODT) files to distribute malware such as RevengeRAT, njRAT and AZORult. The purpose of using ODT files is to avoid detection by antivirus engines while infecting systems.

Coming to vulnerabilities, Ghidra, a free and open-source software reverse-engineering tool from the National Security Agency, has been found to be affected by a medium severity flaw. It impacts the versions up to 9.0.4 and can allow a remote attacker to compromise exposed systems.
