Social media impersonation is a growing concern for security leaders, but the headline claim needs context: a 2026 executive survey forecasts that impersonation and defamation will be a leading threat over the next three years. It does not show that social media is already the most powerful attack vector or measure what share of cybercrime starts there.
What the 2026 survey says—and what it does not
CSC’s CISO Outlook 2026 is based on a survey of 300 senior technology and cybersecurity executives, including CISOs, CTOs, CIOs, and heads of cybersecurity. Respondents were surveyed in early 2026 and divided evenly among North America, Europe (including the U.K.), and Asia-Pacific. The findings represent leaders’ assessments and expectations, not a census of attacks. CSC’s survey summary and related coverage describe the results.
One important distinction is time frame: surveyed executives identified domain/DNS hijacking and subdomain takeover as the top cyber threat for 2025, while social media impersonation and defamation ranked first among their expectations for the next three years. These are separate rankings, not evidence that social media led observed incidents in 2025.
| CSC-reported finding | What it measures |
|---|---|
| 72% said their organization’s cybersecurity threats in 2025 were “critical” or “very critical.” | Share of surveyed executives selecting those responses. |
| 86% viewed AI-powered domain generation algorithms (DGAs) as a cybersecurity threat. | Share of surveyed executives who viewed them as a threat. |
| 57% reported using AI-based monitoring and enforcement solutions. | Share of respondents reporting use, not proof of effectiveness. |
| 44% reported using AI for threat detection and fraud prevention. | Share of respondents reporting use, not proof of effectiveness. |
All four percentages are respondent shares from CSC’s 300-person executive survey, not attack rates or independently measured outcomes. CSC operates in the digital brand and security market, a relevant context for interpreting its survey. Its findings do not establish how much cybercrime is attributable to social platforms.

How a fake social account can lead to fraud
Impersonation exploits familiarity. A fraudulent profile may copy a company’s name, logo, or public-facing identity, then use the audience’s existing trust to promote a scheme, spread false claims, or pose as customer support. A fake support account might direct someone to a lookalike website or login page and ask for credentials, payment details, or other sensitive information.
- Phishing: A message or support interaction sends a person to a fake sign-in page.
- Payment fraud: An impersonator claims to resolve a problem or offer a deal, then requests money or financial details.
- Counterfeit sales: A false profile promotes goods as if they came from the real business.
- Reputational harm: An account publishes false or defamatory claims under a brand’s or person’s identity.
These are attack paths described in the coverage, not evidence of how frequently each occurs. The specific risk depends on what the account claims and where it sends people.
Why social profiles, domains, and websites should be viewed together
A social account can be only one part of a campaign. It may point to a lookalike domain or fraudulent website, where the attacker collects information or takes payment. Looking at each surface in isolation can obscure the connection between the profile, the destination, and the impersonated identity.

The goal is to help teams recognize when seemingly separate incidents may belong to the same effort—not to assume every suspicious account and domain are linked.
Where AI fits—and where it does not
AI can help generate plausible messages, imagery, or profiles. Synthetic audio and deepfakes can also be used to impersonate executives or employees. But AI is not a prerequisite for social impersonation: copied branding, deceptive messages, and lookalike domains can be used without it.
Similarly, domain generation algorithms are an established technique and are not inherently AI-powered. CSC’s 86% figure concerns respondents who viewed AI-powered DGAs as a threat; it should not be read as a finding that all DGAs use AI.
What businesses can do to improve their response
CSC’s article recommends treating social impersonation as a cybersecurity issue that requires coordination, rather than leaving it solely to a social media team. This is a response framework, not a guarantee that a particular tool or control will prevent attacks.
- Assign cross-functional ownership. Define how security, social media, legal, brand protection, marketing, and digital teams share investigations and make escalation decisions.
- Monitor relevant public-facing assets. Include social accounts, domains, websites, and other digital properties in the organization’s view of potential impersonation.
- Set an evidence and escalation process. Decide what information teams should preserve, who assesses a suspected incident, and who is authorized to request a takedown.
- Correlate related signals. Give investigators a way to connect a suspicious profile with a lookalike domain or website when evidence supports the link.
- Evaluate coverage and workflow before selecting services. Ask whether a service covers the relevant surfaces, can help correlate activity, and supports clear investigation, escalation, and takedown ownership.
The cited coverage does not provide head-to-head vendor testing or proof that a particular monitoring service prevents these attacks. A tool’s value therefore cannot be inferred from the survey percentages alone.

Mark Flegg, CSC’s Global Director of Security Services, described social media impersonation and defamation as “highly effective” in a discussion of the survey. That is his characterization, not a quantified effectiveness result. The survey supports a narrower conclusion: among the executives CSC surveyed, social impersonation and defamation were expected to be a leading threat over the next three years. It does not establish a measured ranking across all cybercrime or provide consumer-loss totals.
