Since last week, a new hacking group, calling itself ' JHT ,' hijacked a significant number of Cisco devices belonging to organizations in Russia and Iran, and left a message that reads—" Do not mess with our elections " with an American flag (in ASCII art). MJ Azari Jahromi, Iranian Communication and Information Technology Minister, said the campaign impacted approximately 3,500 network switches in Iran, though a majority of them were already restored. The hacking group is reportedly targeting vulnerable installations of Cisco Smart Install Client, a legacy plug-and-play utility designed to help administrators configure and deploy Cisco equipments remotely, which is enabled by default on Cisco IOS and IOS XE switches and runs over TCP port 4786. Some researchers believe the attack involves a recently disclosed remote code execution vulnerability ( CVE-2018-0171 ) in Cisco Smart Install Client that could allow attackers to take full control of the network ...

Cisco is warning of a new critical zero-day IOS / IOS XE vulnerability that affects more than 300 of its switch models. The company identified this highest level of vulnerability in its product while analyzing " Vault 7 " — a roughly 8,761 documents and files leaked by Wikileaks last week, claiming to detail hacking tools and tactics of the Central Intelligence Agency (CIA). The vulnerability resides in the Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software. If exploited, the flaw ( CVE-2017-3881 ) could allow an unauthenticated, remote attacker to cause a reboot of an affected device or remotely execute malicious code on the device with elevated privileges to take full control of the device, Cisco says in its  advisory . The CMP protocol has been designed to pass around information about switch clusters between cluster members using Telnet or SSH. The vulnerability is in the default configuration of affected Cisco devices,...

Every week seems to bring news of another data breach, and it's no surprise why: securing sensitive data has become harder than ever. And it's not just because companies are dealing with orders of magnitude more data. Data flows and user roles are constantly shifting, and data is stored across multiple technologies and cloud environments. Not to mention, compliance requirements are only getting stricter and more elaborate.  The problem is that while the data landscape has evolved rapidly, the usual strategies for securing that data are stuck in the past. Gone are the days when data lived in predictable places, with access controlled by a chosen few. Today, practically every department in the business needs to use customer data, and AI adoption means huge datasets, and a constant flux of permissions, use cases, and tools. Security teams are struggling to implement effective strategies for securing sensitive data, and a new crop of tools, called data security platforms, have appear...
