Hackers Found Using A New Code Injection Technique to Evade Detection
Apr 13, 2018
While performing in-depth analysis of various malware samples, security researchers at Cyberbit found a new code injection technique, dubbed Early Bird , being used by at least three different sophisticated malware that helped attackers evade detection. As its name suggests, Early Bird is a "simple yet powerful" technique that allows attackers to inject malicious code into a legitimate process before its main thread starts, and thereby avoids detection by Windows hook engines used by most anti-malware products. The Early Bird code injection technique "loads the malicious code in a very early stage of thread initialization, before many security products place their hooks—which allows the malware to perform its malicious actions without being detected," the researchers said. The technique is similar to the AtomBombing code injection technique that does not rely on easy-to-detect API calls, allowing malware to inject code into processes in a manner that no a...
