A new malware campaign targeting Afghanistan and India is exploiting a now-patched, 20-year-old flaw affecting Microsoft Office to deploy an array of commodity remote access trojans (RATs) that allow the adversary to gain complete control over the compromised endpoints. Cisco Talos attributed the cyber campaign to a “lone wolf” threat actor operating a Lahore-based fake
An effective cybersecurity strategy can be challenging to implement correctly and often involves many layers of security. Part of a robust security strategy involves performing what is known as a penetration test (pen test). The penetration test helps to discover vulnerabilities and weaknesses in your security defenses before the bad guys discover these. They can
