The Cybersecurity and Infrastructure Security Agency (CISA) has released an advisory noting that Google and Microsoft recently published reports on advanced persistent threat (APT) actors targeting cybersecurity researchers. The APT actors are using fake social media profiles and legitimate-looking websites to lure security researchers into visiting malicious websites to steal information, including exploits and zero-day vulnerabilities. APT groups often use elaborate social engineering and spear phishing schemes to trick victims into running malicious code through malicious links and websites. CISA recommends cybersecurity practitioners to guard against this specific APT activity and review reports from Google and Microsoft for more information. Additionally, CISA strongly encourages cybersecurity practitioners use sandbox environments that are isolated from trusted systems or networks when examining untrusted code or websites. Read the advisory at CISA.
