Hackers are getting more and more getting better at masking their attack's payloads types from detection on such a unique trick. In a recent discovery, cybersecurity has found that attackers are leveraging lesser-known ppam add-on files in PowerPoint to wrap their malicious executables. . Although it's a relatively new technique, such files are sent via phishing emails which continue to be a popular attack vector for cybercriminals.
Another cyber-espionage campaign that leveraged the spear-phishing method was also found targeting various government and media organizations in Europe. Dubbed Operation EmailThief, the campaign was attributed to a threat actor named TEMP_Heretic. In other updates, a new threat actor group named Antlion managed to stay under the radar for months to distribute a custom backdoor called xPack.
