Cyber Threat Actor: Mysterious Team

Mysterious Team,also known as Team Bangladesh, Mysterious Bangladesh Hackers and Mysterious Team Bangladesh, is a hacktivist group that claims to consist of cyber warriors from Bangladesh. The group has used multiple aliases in public statements and on social media platforms. It presents itself as a loose collective of individuals motivated by hacktivist causes rather than financial gain.

The actors have targeted government institutions, educational bodies and private sector services across several countries. In May 2023 they launched a distributed denial‑of‑service attack that rendered the La Poste website unavailable in France, citing retaliation for remarks made by a French researcher. Also in May 2023 they conducted DDoS attacks against numerous Senegalese government websites, stating they were working for justice for innocent people in that country. In December 2022 the group compromised the Indian Central Board of Higher Education, exfiltrating personal data such as names, Aadhaar numbers and financial codes and gaining access to the administrative panel. Earlier in September 2022 they directed HTTP flood DDoS attacks at websites belonging to several Indian state governments, including those of Assam, Madhya Pradesh, Uttar Pradesh, Gujarat, Punjab and Tamil Nadu. Their actions demonstrate a focus on disruption through service denial and on data acquisition that could enable further malicious activity.

The group’s typical tooling relies on distributed denial‑of‑service scripts and HTTP flood techniques. They have employed a tool referred to as ‘Raven Storm’ to generate high volumes of traffic against target servers. Beyond DDoS, the actors have shown the ability to obtain unauthorized access to administrative panels, as seen in the CBHE breach, and to deface domain directories. The stolen information from the Indian education entity included personally identifiable data that could be used for brute‑force attempts, ransomware preparation or network persistence. The group also uses social media platforms such as Twitter, Facebook and Telegram to claim responsibility and to disseminate messages.

Public reporting links Mysterious Team to an Indonesia‑based hacktivist collective known as ‘Hacktivist of Garuda’. They have also been noted for engaging in mass reporting of content on platforms like YouTube, Facebook and LinkedIn as part of their online activities. No explicit connection to a state sponsor or a formal criminal consortium has been documented in the sources reviewed.

Representative operations include the May 2023 La Poste DDoS incident, the May 2023 Senegalese government website outage, the December 2022 CBHE data compromise and the September 2022 Indian state‑government DDoS campaign. Each of these episodes was publicly claimed by the group and corroborated by third‑party observations such as DownDetector spikes, government statements or cybersecurity advisories. Together they illustrate a pattern of using denial‑of‑service to disrupt services and of exploiting administrative interfaces to harvest sensitive data.
