Speaking at the RSAC 365 Digital Summit Jason Rivera, director, Strategic Menace Advisory Group at CrowdStrike, explored how the COVID-19 well being disaster has fundamentally altered the attack surface for businesses across the environment.
“We had to use the internet so substantially far more than we at any time have in the past. If we use the internet more, then we have a greater, extra elaborate attack area. That in flip will allow adversaries options they did not have prior to.”
Rivera outlined a few distinctive means in which the attack surface has altered in the put up-pandemic earth when in comparison to right before the well being disaster commenced.
The initially fears interior aspects, he ongoing. Pre-COVID, inner property these as critical workloads/endpoints, programs and knowledge were contained inside defined network boundaries. Changeover to remote functioning has resulted in an exponential boost of publicity to inside assets, implying extra emphasis on defending workloads and endpoints.
The second factor Rivera referred to problems network perimeters. Pre-COVID, in-person workplaces ended up largely reliant on firewalls, actual physical appliances, email gateway and network security alternatives. Put up-COVID, remote working specifications have pressured the mass use of VPN and RDP technologies, which position higher strain on perimeter security.
The 3rd factor cited by Rivera was that of external variables. Pre-COVID, there was a obvious differentiation concerning inner and exterior environments with an internet characterized by ‘normal’ ranges of traffic. Put up-COVID, there has been improved reliance on cloud capabilities, blurring the strains in between interior and external belongings, even though internet targeted traffic has developed exponentially.
Rivera outlined how, as organizations were confronted by this sort of issues, adversaries levied practices designed precisely to exploit pandemic-induced attack floor changes.
“Our adversaries have shown their functionality to rapidly adapt,” he stated, with web distribution, situational phishing, remote desktop exploitation and COVID-themed lures all proving to be common themes.
Attackers, equally of a criminal and state-sponsored character, have also shifted tactics from big game ransomware hunting, information theft and fraud, nationwide security/financial espionage and interior influencing to ransom-as-a-support, facts extortion, themed downloaders and epidemiological tech and conclusion earning throughout the system of the pandemic, Rivera described.
Addressing how corporations can protect against the heightened cyber-risks brought about by the pandemic, Rivera said it is a “situation of evolve or get left driving,” proposing 4 critical locations of evolution to concentration on:
To conclude, Rivera claimed: “Your means to defeat cyber-threats rests almost totally on your knowledge of the [security] difficulty[s]” your group faces.
