  Introduction: In the world of cybersecurity, attackers continuously explore new techniques to bypass network defenses and exfiltrate sensitive information. One such technique gaining prominence is DNS tunneling. DNS tunneling allows attackers to use the DNS protocol as a covert communication channel, exploiting its ubiquitous nature and inherent characteristics. This blog post delves into the concept of DNS tunneling, its working mechanism, potential risks, and methods to mitigate this emerging threat. Understanding DNS Tunneling: DNS (Domain Name System) is the backbone of the internet, responsible for translating domain names into IP addresses. Its primary purpose is to facilitate communication between devices. However, this fundamental protocol can be manipulated to serve as a covert channel for data transmission. DNS tunneling involves encapsulating data within DNS queries and responses, effectively bypassing network security measures that may not scrutinize DNS traffic as c...

The government  hack of an iPhone  used by a San Bernardino killer serves as a reminder that phones and other electronic devices aren't impenetrable vaults. While most people aren't targets of the  NSA , FBI or a foreign government, hackers are looking to steal the financial and personal information of ordinary people. Your phone stores more than just selfies. Your email account on the phone, for instance, is a gateway to resetting banking and other sensitive passwords. Like washing your hands and brushing your teeth, a little "cyber hygiene" can go a long way toward preventing disaster. Lock your phone with a passcode Failing to do so is like leaving your front door unlocked. A four-digit passcode - and an accompanying self-destruct feature that might wipe a phone's data after too many wrong guesses - stumped the FBI for weeks and forced them to bring in outside help. Using six digits makes a passcode 100 times harder to guess. And if you want to m...
