A "potentially destructive actor" aligned with the government of Iran is actively exploiting the well-known  Log4j vulnerability  to infect unpatched VMware Horizon servers with ransomware. Cybersecurity firm SentinelOne dubbed the group " TunnelVision " owing to their heavy reliance on tunneling tools, with overlaps in tactics observed to that of a broader group tracked under the moniker  Phosphorus  as well as Charming Kitten and Nemesis Kitten. "TunnelVision activities are characterized by wide-exploitation of 1-day vulnerabilities in target regions," SentinelOne researchers Amitai Ben Shushan Ehrlich and Yair Rigevsky  said  in a report, with the intrusions detected in the Middle East and the U.S. Also observed alongside Log4Shell is the exploitation of Fortinet FortiOS path traversal flaw ( CVE-2018-13379 ) and the Microsoft Exchange  ProxyShell  vulnerability to gain initial access into the target networks for post-exploitation. "Tunne...

These days, businesses all around the world have come to depend on cloud platforms for a variety of mission-critical workflows. They keep their CRM data in the cloud. They process their payrolls in the cloud. They even manage their HR processes through the cloud. And all of that means they're trusting the bulk of their privileged business data to those cloud providers, too. And while most major cloud providers do a decent job of keeping data secure, the majority of business users take an upload-it-and-forget-it approach to their data security needs. And that — needless to say — is dangerous. In reality, cloud providers can only protect a business's data if the business does its part by adhering to some cloud security best practices. And fortunately, they're not that complicated. Here are the four most important cloud security best practices businesses should build into their cloud operations right away. Never Skip Selection Due Diligence The first cloud security best p...

Cisco has released security updates to contain three vulnerabilities affecting its products, including one high-severity flaw in its Email Security Appliance (ESA) that could result in a denial-of-service (DoS) condition on an affected device. The weakness, assigned the identifier CVE-2022-20653 (CVSS score: 7.5), stems from a case of insufficient error handling in  DNS  name resolution that could be abused by an unauthenticated, remote attacker to send a specially crafted email message and cause a DoS. "A successful exploit could allow the attacker to cause the device to become unreachable from management interfaces or to process additional email messages for a period of time until the device recovers, resulting in a DoS condition," the company  said  in an advisory. "Continued attacks could cause the device to become completely unavailable, resulting in a persistent DoS condition." The flaw impacts Cisco ESA devices running Cisco AsyncOS Software running vers...

Google on Wednesday announced plans to bring its Privacy Sandbox initiatives to Android in a bid to expand its privacy-focused, but also less disruptive, advertising technology beyond the desktop web. To that end, the internet giant said it will work towards building solutions that prevent cross-app tracking à la Apple's App Tracking Transparency ( ATT ) framework, effectively limiting sharing of user data with third-parties as well as eliminating identifiers such as advertising IDs on mobile devices. "The Privacy Sandbox on Android builds on our existing efforts on the web, providing a clear path forward to improve user privacy without putting access to free content and services at risk," Anthony Chavez, vice president of product management for Android security and privacy,  said . Privacy Sandbox , launched in 2019, is Google's umbrella term for a set of technologies that will phase out third-party cookies and curb covert tracking, like  fingerprinting , by redu...
