After the outbreak of WannaCry and Petya ransomwares, which spread around the world causing widespread disruption earlier this year, a new strain, dubbed as Bad Rabbit, has affected systems in Russia, Ukraine, Germany and Turkey.
Ransomware, as the name suggests, is a type of malware that encrypts a user’s data, refusing to release it unless a ransom is paid. The ransom is typically paid in the digital currency Bitcoin.
Unlike the previous damaging ransomwares, Bad Rabbit malware spreads through “drive-by attacks,” disguised as an Adobe Flash installer, after accessing insecure websites. Once clicked on the malicious installer, the computer goes on a lockdown.
Following the attack, Bad Rabbit asks for a ransom of 0.05 bitcoins, which is about $280, reports BBC.
Following the worldwide cyber attacks, first in May and second on June 27, the Crime Research and Analysis Foundation (CRAF) reported a total of 30 personal computers in Dhaka and Chittagong were affected by the WannaCry ransomware. Apart from personal computers, private universities and television channels had also become victims to the ransomware.

While India was hit with the second malware, there were no reports of cyber attack in Bangladesh.
Analysts believe that the new strain and the third major-spread ransomware of this year, Bad Rabbit, may become equally dangerous like its predecessors.
reported that Bad Rabbit attacks have been recorded in Russia’s Interfex news agency, media websites, such as St Petersburg-based Fontanka.ru, and an airport in Ukraine's Odessa and a subway system in Kiev.
Internet Service Providers Association of Bangladesh (ISPAB) President Aminul Hakim said: “We have not received any reports or complaints of ransomware attack in the country.”
The president thinks that everyone must remain aware and careful, even though Bangladesh hasn’t been attacked. He has advised computer users to be cautious.
He said that despite having many methods of blocking an attack, it is not enough. “Since the blocking methods haven’t arrived in Bangladesh yet, everyone should be more careful,” he said.
Ransomware virus can spread in various ways. Cyber security experts have advised not clicking on any unfamiliar links, and deleting emails from unknown addresses. Furthermore, software used on devices should always be updated.
