∗∗∗ Konami Code Backdoor Concealed in Image ∗∗∗
---------------------------------------------
Attackers are always looking for new ways to conceal their malware and evade detection, whether it’s through new forms of obfuscation, concatenation, or — in this case — unorthodox use of image file extensions.
