The novel variant of the banking Trojan Mispadu is targeting Latin American countries, especially Mexico, by exploiting a flaw in Windows SmartScreen. In this latest distribution method, the attackers send spam emails that deliver deceptive URL files that circumvent the SmartScreen banner warning.
Delivering more proof that the Log4Shell vulnerability is endemic, Akamai researchers detected botnet malware updated to use the flaw as an infection vector. Log4Shell burst into public awareness in late 2021 when security researchers identified a flaw in the ubiquitous Apache Log4J 2 Java library.
U.S. federal agencies have until midnight Friday to disconnect Ivanti VPN devices and perform a factory reset before reconnecting them to the network. Fifteen agencies use the gateways, which were hit by likely Chinese hackers in an espionage campaign and are riddled with zero-day vulnerabilities.
The FBI announcing that it has forcibly removed "KV Botnet" Chinese nation-state malware from "hundreds" of poorly secured SOHO routers across America highlights the risk posed by the growing volume of outdated IoT devices. The FBI's fix is temporary, and we need a more permanent solution.
Corporate VPN maker Ivanti on Wednesday began a belated patch rollout for zero-day flaws that many cybersecurity firms say paved the way for an espionage hacking operation likely conducted by China. Ivanti also disclosed two more zero-days and told customers that hackers are exploiting one of them.
Hackers are scanning the internet looking for vulnerable instances of the Jenkins server used by software developers for continuous integration and continuous delivery. There are approximately 45,000 exposed Jenkins servers susceptible to a critical remote code execution flaw.
In this webinar, we will demystify the complexities of RMM technology and unlock how RMM solutions empower small to medium-sized businesses (SMBs) to protect their most valuable asset - their data. We will explore real-life scenarios and success stories that showcase the transformative impact of RMM on data security...
The U.S. Cybersecurity and Infrastructure Security Agency directed federal agencies to implement mitigation measures for two zero-day exploits that affect Ivanti’s popular VPN products while they await a patch, in what one official described as "a rapidly evolving situation."
