Tabletop exercises look a little different this year • The Register

It is probably the most fantastic time of the yr … for company safety bosses to run tabletop workout routines, simulating a hypothetical cyberattack or different emergency, operating by means of incident processes, and practising responses to make sure preparedness if when a digital catastrophe happens.

“We’re finally testing how resilient is the group,” stated Palo Alto Networks Chief Safety Intelligence Officer Wendi Whitmore in an interview with The Register. “It isn’t if we get attacked, it is: How rapidly will we reply and include these assaults.” 

And this yr, organizations must account for the pace of AI, each by way of how attackers use these tools to search out and exploit bugs, and the way defenders can use AI in their response.

“Menace actors are exploiting CVEs at an increased rate with AI,” Google Cloud’s Workplace of the CISO Public Sector Advisor Enrique Alvarez advised The Register. “Tabletop workout routines ought to take into account a situation the place a CVE is printed affecting a software program system in use by the corporate with an instantaneous exploit by way of a cyber adversary.”

Whitmore stated her risk analysts see a vulnerability launched with exploits tried inside 5 minutes. 

“On the defender facet, like our personal SOC: We’re 90 billion assault occasions coming in per day, which we are able to synthesize down into 26,000 which might be correlated, after which one per day that requires human guide intervention of tier-three analysts to dive in, and run further queries and evaluation,” she added.

Certainly, if 2025 taught us something, it is that criminals and state-backed threat actors are more and more adding AI to their arsenals, whereas enterprises’ AI use vastly expands their attack surface. 

From the attackers’ facet, this implies extra focused, convincing phishing emails, faster reconnaissance and scanning for vulnerabilities, and troves of delicate knowledge that may be quickly scanned and stolen. In the meantime, defenders want to make sure their LLMs aren’t leaky, and AI brokers aren’t accessing data that they should not have entry to.

The Reg requested a number of incident responders to weigh in on finest practices for these year-end tabletop workout routines as they face extra AI generated or assisted assaults, and take measures to safe their inner AI programs and fashions.

Tabletop workout routines now must replicate two realities: attackers utilizing AI to maneuver sooner, quieter, and at huge scale, and attackers concentrating on the AI programs we deploy

“Tabletop workout routines now must replicate two realities: attackers utilizing AI to maneuver sooner, quieter, and at huge scale, and attackers concentrating on the AI programs we deploy,” Tanmay Ganacharya, VP of Microsoft risk safety analysis, advised The Register.

“One of the best workout routines simulate adaptive, AI-powered phishing and speedy shifting assault chains, whereas additionally making ready groups for situations concentrating on AI programs like immediate injection, misconfiguration, and AI-driven knowledge exfiltration,” Ganacharya stated. “The purpose is to rehearse sooner choices, confirm data in low belief environments, and guarantee groups perceive how AI modifications each stage of the kill chain.”

In the end, the purpose of those workout routines is to teach each the C-suite and technical responders about what can occur, and for them to apply their responses to numerous safety situations whereas figuring out areas for enchancment.

“As a lot as it’s about establishing muscle reminiscence and making certain that you’ve a great course of and might execute towards that course of, it is also simply as a lot about schooling,” Mark Lance, GuidePoint safety VP of digital forensics and incident response and risk intel, advised The Register. “So as an example, a senior management staff studying about ransomware sometimes walks away from it saying, ‘I do know extra about this and the potential dangers and threats related to it.'”

Utilizing AI to battle AI

A technique organizations can account for the inflow of AI-related threats is to make use of AI to develop situations, stated Invoice Reid, a safety advisor to healthcare and life sciences organizations in Google Cloud’s Workplace of the CISO. “Wish to check AI fakes? Make one and use it within the tabletop train,” he advised The Register.

Along with utilizing AI to develop the workout routines, corporations must also use it to “measure and facilitate workout routines and outcomes,” stated Taylor Lehman, director of Google Cloud Workplace of the CISO’s healthcare and life sciences division.  

“Expose details about your surroundings – like threats, controls, vulnerabilities, belongings of every kind, key dangers, stakeholders, buyer personas, and many others. – to AI programs who can then assist craft very significant and really particular, reasonable situations that may provide help to hone the situation and ship particular varieties of outcomes you need as a part of an train,” Lehman advised The Register.

Different new-ish AI threats embody deepfakes, and this particularly impacts Google Cloud’s monetary providers shoppers, Alvarez stated. Due to this, many organizations within the monetary sector have – or ought to – add deepfakes, each audio and video, to their situations.

“Nonetheless, using AI-generated assaults will not be solely deepfakes,” Mandiant Consulting director David Wong stated. “AI can be utilized in every stage of the assault lifecycle and will increase the amount and pace of the assaults. Designers of tabletop workout routines should adapt to the pace and quantity of their situations.”

When a deepfake CEO calls for a cash switch, the drill should not be about detection software program, however strictly testing a compulsory out-of-band verification by way of a regular cellphone name

Alvarez additionally suggests reaching out to a local FBI Field Office and asking the Cyber Assistant Particular Agent in Cost (ASAC) if they’ll present an agent to take part. “It is a good option to set up a point-of-contact on the discipline workplace for future reference and communication,” he stated, including that for full-scale workout routines together with C-suite, board members, and different inner stakeholders, take into account reaching out to CISA to take part, too. 

CISA, the US Cybersecurity and Infrastructure Safety Company, additionally gives several free resources designed to assist corporations conduct their very own workout routines overlaying a spread of risk situations.

One Google Cloud Workplace of the CISO senior marketing consultant, Anton Chuvakin, advocated for analog – and warning – on the subject of “preventing AI with extra AI. As a substitute, focus your tabletop workout routines on introducing analog friction to interrupt the adversary’s pace,” he advised The Register. “When a deepfake CEO calls for a cash switch, the drill should not be about detection software program, however strictly testing a compulsory out-of-band verification by way of a regular cellphone name.”

Plus, do not rely solely on on-line recordsdata, he added. “Workouts should apply reverting to minimal viable enterprise operations, using offline golden copies of information and sturdy approval processes that an algorithm can’t spoof,” Chuvakin stated. “If you cannot belief what you see on the display screen, your strongest protection is definitely course of, not know-how.”

Who ought to take part?

All of the consultants The Reg talked with advisable no less than one or two tabletops per yr, and tailoring these workout routines to particular audiences, separating C-suite leaders and technical responders, for instance. 

“From my prior FBI expertise, the overwhelming majority of corporations have by no means accomplished a tabletop train,” Alvarez stated. “A very good start line or purpose must be no less than twice a yr with the second tabletop train incorporating the teachings discovered from the primary.” 

Participation ought to range primarily based on the situation, in accordance with Ganacharya, with the C-suite collaborating “no less than semiannually as a result of AI-powered assaults demand government stage choices.”

Technical drills, akin to trialing new ransomware procedures, might solely require the Safety Operations Middle (SOC) and incident response groups, whereas high-impact situations like insider leaks and reputational threat must also embody authorized, PR, HR and senior management.

Different operational leaders might require extra frequent workout routines with focused situations, Ganacharya stated. This consists of deputies, administrators, and SOC leaders – the those who executives depend on to hold out day-to-day operations.

And, as all the time, keep in mind Murphy’s Regulation. As Ganacharya put it: “Each train ought to embody alternates, as a result of actual incidents not often occur when your first selection responder is out there.” ®
