Why "Thokomocom"?
The name "Thokomocom" was coined by the researchers who discovered it. In the cybersecurity community, naming vulnerability chains (like "Shellshock," "Heartbleed," or "ProxyLogon") helps administrators quickly identify and reference the specific exploit chain without listing multiple CVE numbers every time. Thokomocom 2021: A Comprehensive Retrospective on the Thoko
Memetic Evolution: How Thokomocom Changed Language
Beyond the dance, the vocal component of Thokomocom entered the South African lexicon. The signature ad-libs—"Washa!" "Skrr thoko!" and "Kokota"—became slang for "to handle business" or "to finish a task with flair." Unusual requests to the /ecp/ endpoint
By the end of 2021, you didn't have to dance to "do a Thoko." A student finishing a test quickly would say, "I Thokomocommed that exam." A chef plating a dish would yell "Washa!" in the kitchen. This linguistic shift is rare for a dance trend, elevating thokomocom from a physical action to a cultural attitude.
2. Review Exchange Logs
Since the exploit requires authentication, checking your logs for anomalies is crucial. Look for:
Unusual requests to the /ecp/ endpoint.
Strange behavior from users who typically have low activity.
Unexpected child processes spawning from the IIS worker process (w3wp.exe).
The Technical Breakdown
The Thokomocom vulnerabilities stem from issues within the Exchange Control Panel (ECP) and how Exchange handles deserialization and authentication tokens.
The Flaw: The vulnerabilities allow an authenticated attacker to perform Remote Code Execution (RCE).
The Attack Vector: Unlike ProxyLogon (which could be exploited pre-authentication in certain configurations), Thokomocom generally requires valid credentials. However, the impact is just as severe. Once an attacker has a foothold (even a low-privilege user account), they can exploit the deserialization flaw to execute arbitrary commands as the SYSTEM user.
The Impact: Complete takeover of the Exchange Server. Since Exchange runs with high privileges, an attacker can compromise the entire Active Directory environment.
