Hacktivist group attacks Hungarian websites

According to CyberThreat Report, the hacktivist group Mysterious Team Bangladesh targeted Hungarian government, infrastructure websites and Daily News Hungary in a cyberattack as part of the OpRevenge campaign, which also named Israel and several EU Member States as targets. Over three days, culminating on 28 February, the group deployed distributed denial-of-service (DDoS) attacks to disrupt website functionality. It exploited SQL injection vulnerabilities on poorly secured sites without targeting strategic assets. While the attacks did not cause lasting damage, they highlight the growing sophistication of hacktivist groups and Hungary’s increasing presence in international cyber conflicts, underscoring the need for stronger cybersecurity measures against politically motivated threats.

Mysterious Team Bangladesh

The hacktivist group Mysterious Team Bangladesh has been active since 2020, carrying out politically motivated cyberattacks, primarily using DDoS techniques and website vulnerability exploitation. Strongly anti-Israel and pro-Palestinian, the group targets countries it views as Israeli allies, often invoking the fight against Zionism and the protection of Muslim communities. Their latest campaign, OpRevenge, has mainly focused on European nations, including Hungary, Germany, France, and Belgium, as well as Israel. Since 2022, the group has launched over 750 DDoS attacks and numerous website defacements, previously targeting India and Israel before expanding into Europe. Operating via Telegram and encrypted channels, they time their attacks to align with geopolitical events, using cyber operations as a means of political protest.

Despite its name, the hacktivist group Mysterious Team Bangladesh may not be exclusively composed of Bangladeshi members, as such groups often operate internationally under a shared “brand.” While some attacks have originated from Bangladeshi IP addresses and the group communicates in Bengali and English, the use of VPNs and proxies complicates attribution. The group collaborates with other hacktivist organisations, such as North Africa’s Keymous+, and may receive external support, potentially even from state-sponsored entities. Their politically motivated cyber operations, including the recent OpRevenge campaign, specifically target countries viewed as Israeli allies.
