threat updates
GLOBAL
WhatsApp users were urged to install
an update after a vulnerability was found
in the app that could have allowed users’
phones to have been compromised.
In a security advisory, WhatsApp stated that a buffer
overflow vulnerability in the WhatsApp VOIP stack had allowed
remote code execution via a specially crafted series of SRTCP
packets sent to a target phone number.
Updates were made available and WhatsApp users were advised
to install these as soon as possible.
GLOBAL
Sophos, a global leader in endpoint and network security,
reported that MegaCortex – a relatively little-seen malware –
suddenly spiked in volume on May 1.
Sophos has seen MegaCortex detections in the US, Canada,
Argentina, Italy, the Netherlands, France, Ireland, Hong Kong,
Indonesia and Australia.
The ransomware has manual components similar to Ryuk and
BitPaymer, but the adversaries behind MegaCortex use more
automated tools to carry out the attack – which is unique.
