2. WooCommerce Credit Card Stealer Found Implanted in Random Plugins
   "As elaborated, the malware didn’t precisely run as a script on the infected web page. Instead, the malware ran on the backend.

5. How Cybercriminals Are Using Bitcoin’s Blockchain to Make Botnets Stronger Than Ever
   " instead of hard-coding web domains into the malware, they hard-coded three Bitcoin wallet addresses into it. With these addresses, Glupteba has managed to set up an infallible interface between its bot herds and its C2 infrastructure via a little-known function known as the “OP_Return.” The OP_Return is a controversial feature of Bitcoin wallets that allows for the entry of arbitrary text into transactions. It basically functions as the crypto equivalent of Venmo’s “memo” field. Glupteba has taken advantage of this feature by using it as a communication channel. "
