Beyond Opportunistic: How the Threat Landscape Is EvolvingChester Wisniewski of Sophos Describes the 'Blended Threat'
The threat landscape continues to evolve, says Chester Wisniewski of Sophos. "The more professional, the more skilled criminals out there are moving, seemingly, away from this 'spray and pray' mass exploitation approach and getting more targeted. It's what I call a blended threat,” he says.
"It begins out opportunistic, meaning they may just be scanning the internet for people that are running a particular kind of database that has a vulnerability or they may be looking for insecure open remote access things like RDP. But once they find that you've left the door ajar … then a human being takes over and that human being is one, going to go for the easiest targets in your organization, and two, they're going to be much more selective on how they go about it. It's sort of like a malicious penetration test."
In a video interview at the recent Infosecurity Europe conference, Wisniewski discusses:
- How ransomware attackers are shifting from email distribution to directly infecting servers;
- Why identity and authentication is increasingly a social problem;
- As attackers shift tactics, identifying which processes and security policies to adjust.
