| Texte | Commodity malware usage surpasses ransomware by narrow margin  By Caitlin Huey.For the first time in more than a year, ransomware was not the top threat Cisco Talos Incident Response (CTIR) responded to this quarter, as commodity malware surpassed ransomware by a narrow margin. This is likely due to several factors, including the closure of several ransomware groups, whether it be of their own volition or the actions of global law enforcement agencies and governments.  Commodity malware was the top observed threat this quarter, a notable development given the general decrease in observations of attacks leveraging commodity trojans in CTIR engagements since 2020. These developments coincide with a general resurgence of certain email-based trojans in recent months, as law enforcement and technology companies have continued to attempt to disrupt and affect email-based malware threats like Emotet and Trickbot. This quarter featured malware such as the Remcos remote access trojan (RAT), Vidar infostealer, Redline Stealer and Qakbot (Qbot), a well-known banking trojan that in recent weeks, has been observed in new clusters of activity delivering a variety of payloads. TargetingThe top-targeted vertical continues to be telecommunications, following a trend where it was among the top targeted verticals in Q4 2021 and Q1 2022, closely followed by organizations in the education and health care sectors.  Commodity malwareThis quarter saw a notable increase in commodity malware threats compared to previous quarters. Commodity |
