Description
On July 10, 2020, Temple Sinai in Hartford, Connecticut, experienced a disruptive intrusion during its virtual prayer service conducted via Zoom and Facebook Live. The service, attended by approximately 200 congregants, was targeted by an unidentified malicious actor who gained unauthorized access to the online platform. The attacker utilized Zoom’s annotate feature to superimpose swastikas on the shared screen during the congregation’s recitation of the Mourner’s Kaddish, a sacred Jewish prayer for deceased relatives. Simultaneously, the perpetrator flooded the chat function with offensive messages and hijacked the audio system to play klezmer music, a traditional Jewish genre with cultural roots in Eastern Europe. Rabbi Jeffrey Bennett identified the intrusion as it occurred and immediately halted screen sharing to sever the visual component of the attack. A co-host concurrently muted all participants’ audio, effectively neutralizing the disruption within three seconds of its initiation. The temple’s board of directors promptly notified congregants about the incident via written communication but resumed the service without additional interruptions.
This marked the first and only anti-Semitic breach since Temple Sinai transitioned to online services in March 2020 due to COVID-19 precautions. Although the intrusion lasted mere seconds, Rabbi Bennett emphasized its profound symbolic impact, stating the duration was "three seconds too long." The attack specifically disrupted a spiritually significant moment of communal mourning but did not deter subsequent participation. Temple leadership filed an incident report with the Anti-Defamation League (ADL) and notified Zoom about the security violation. No technical details regarding the attacker’s entry method or Zoom’s infrastructure vulnerabilities were disclosed in available reports. Bennett affirmed the congregation’s resilience, noting the incident reinforced their commitment to religious observance. No further disruptions occurred following the implementation of unspecified preventive measures by the temple. The ADL had previously documented escalating anti-Semitic incidents in the United States, including a record 2,100 cases in 2019, contextualizing the attack within broader patterns of harassment targeting Jewish communities.
