Threat Intel Update

Cyber actors employ a diverse range of tools and strategies to carry out attacks, ranging from cutting-edge technologies like artificial intelligence (AI) to the manipulation of legitimate tools or acquisition of authentic login credentials. These tools enable cyber actors to steal data, execute ransomware attacks, or persist covertly within compromised systems for extended periods. The motives and objectives of cyber actors vary, whether they are aligned with foreign interests or affiliated with criminal syndicates. Nonetheless, safeguarding computer systems is a collective goal, necessitating a combination of software defenses, robust policies, adherence to government regulations, and collaboration among different teams within organizations and with external entities in both public and private sectors.
