A newly discovered cyberespionage group has been targeting hotels worldwide around the world since at least 2019, as well as higher-profile targets such as governments, international organizations, law firms, and engineering companies. Slovakian internet security firm ESET spotted the hacking group and described it as an "Advanced persistent threat."

Unidentified threat actors breached a server running an unpatched, 11-year-old version of Adobe's ColdFusion 9 software in minutes to remotely take over control and deploy file-encrypting Cring ransomware on the target's network 79 hours after the hack. "Devices running vulnerable, outdated software are low-hanging-fruit for cyberattackers looking for an easy way into a target," Sophos principal researcher Andrew Brandt said.

Citizen Lab released a report on a zero-click iMessage exploit that is used in NSO Group’s Pegasus spyware. Apple patched the vulnerability; everyone needs to update their OS immediately. News...

Threat actors are sharing Windows MSHTML zero-day tutorials and exploits on hacking forums, allowing other hackers to start exploiting the new vulnerability in their own attacks. Last Tuesday, Microsoft disclosed a new zero-day vulnerability in Windows MSHTML that allows threat actors to create malicious documents, including Office and RTF docs, to execute commands on a victim's computer remotely.

Eoin Keary, CEO and founder of Edgescan, told The Register that the oldest common vulnerability discovered in its latest quarterly vulnerability scans report dated back to 1999. Before we look at the why, let's explore some of the what: the old vulnerabilities that are still being used in very real world enterprise attacks to this day.

Cisco has patched a critical security vulnerability impacting its Enterprise Network Function Virtualization Infrastructure Software that could be exploited by an attacker to take control of an affected system. The network equipment maker said it's aware of a publicly available proof-of-concept exploit code targeting the vulnerability, but added it's not detected any successful weaponization attempts in the wild.

The Conti ransomware gang is hacking into Microsoft Exchange servers and breaching corporate networks using recently disclosed ProxyShell vulnerability exploits. ProxyShell is the name of an exploit utilizing three chained Microsoft Exchange vulnerabilities that allow unauthenticated, remote code execution on unpatched vulnerable servers.

A critical vulnerability that affects Cisco Enterprise NFV Infrastructure Software has been patched and Cisco is urging enterprise admins to quickly upgrade to a fixed version, as proof-of-concept exploit code is already available. The bug could be exploited by remote attackers to bypass authentication and log in to an affected device as an administrator.

Cisco has patched a near-max critical bug in its NFVIS software for which there's a publicly available proof-of-concept exploit. On Wednesday, Cisco released patches for the flaw - an authentication bypass vulnerability in Enterprise NFV Infrastructure Software that's tracked as CVE-2021-34746.

Cisco has addressed an almost maximum severity authentication bypass Enterprise NFV Infrastructure Software vulnerability with public proof-of-concept exploit code.CVE-2021-34746 is caused by incomplete validation of user-supplied input passed to an authentication script during the sign-in process which allows unauthenticated, remote attackers to log into unpatched device as an administrator.
