The new aLTEr attack can be used against nearly all LTE connected endpoints by intercepting traffic and redirecting it to malicious websites. This article summarizes how the attack works, and suggests ways to protect yourself from it – including a specific approach for Apple iOS devices.
Most organizations have a firewall that acts as a filter between their sensitive internal networks and the threatening global Internet. DNS tunneling has been around for a while. But it continues to cost companies and has seen hackers invest more time and effort developing tools. A recent study[1] found that DNS attacks in the UK alone have risen 105% in the past year. DNS tunneling is attractive–hackers can get any data in and out of your internal network while bypassing most firewalls. Whether it’s used to command and control (C&C) compromised systems, leak sensitive data outside, or to tunnel inside your closed network, DNS Tunneling poses a substantial risk to your organization. Here’s everything you need to know about the attack, the tools and how to stop it.

This Joint Cybersecurity Advisory was coauthored by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Australian Cyber Security Centre (ACSC), the United Kingdom’s National Cyber Security Centre (NCSC), and the U.S. Federal Bureau of Investigation (FBI).
This advisory provides details on the top 30 vulnerabilities—primarily Common Vulnerabilities and Exposures (CVEs)—routinely exploited by malicious cyber actors in 2020 and those being widely exploited thus far in 2021.
Cyber actors continue to exploit publicly known—and often dated—software vulnerabilities against broad target sets, including public and private sector organizations worldwide. However, entities worldwide can mitigate the vulnerabilities listed in this report by applying the available patches to their systems and implementing a centralized patch management system.
