Gaza Cybergang users altering voices to audio like ladies?
On Tuesday, Cado Security issued an odd report offering new details on the toolkits employed by actors affiliated with the Middle Jap, Arabic talking APT group recognized as MoleRats, or the Gaza Cybergang. The team is recognized to focus on Palestine- and Israel-based pursuits, officers or institutions and, in the earlier, sure Western targets.
