A security lapse by cybercriminals can be a major boon for security experts and this is what has happened in the case of the notorious Emotet trojan. A buffer overflow vulnerability in Emotet discovered by cybersecurity experts enabled them to create a kill switch called EmoCrash which prevented the trojan from infecting users. Though the kill switch was short-lived - alive for 182 days - it helped many susceptible organizations to thwart the attacks by Emotet between February 6, and August 6, 2020.
The past 24 hours also witnessed some major blow from ransomware attackers. The Japanese technology giant, Konica Minolta, and the US spirit and wine giant, Brown Forman, disclosed that their systems and networks were affected after being hit by ransomware attacks.
