By Nate Pors and Terryn Valikodath.   Executive summary  In a recent malspam campaign delivering the Qakbot banking trojan, Cisco Talos Incident Response (CTIR) observed the adversary using aggregated, old email threads from multiple organizations that we assess were likely harvested during the 2021 ProxyLogon-related compromises targeting vulnerable Microsoft Exchange servers.  This campaign relies on external thread hijacking, whereby the adversary is likely using a bulk aggregation of multiple organizations’ harvested emails to launch focused phishing campaigns against previously uncompromised organizations. This differs from the more common approach to thread hijacking, in which attackers use a single compromised organization’s emails to deliver their threat.  This many-to-one approach is unique from what we have generally observed in the past and is likely an indirect effect of the widespread compromises and exfiltration of large volumes of email from 2020 and 2021.  Understandi...

The financial services industry has always been at the forefront of technology adoption, but the 2020 pandemic accelerated the widespread of mobile banking apps, chat-based customer service, and other digital tools. Adobe's 2022 FIS Trends Report, for instance, found that more than half of the financial services and insurance firms surveyed experienced a notable increase in digital/mobile

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 ...

Maintainers warn to patch all versions of open source web app framework – even those not deemed vulnerable

Inadequate access control and CSRF protections spawn critical and high severity issues

Dark Reading's weekly roundup of all the OTHER important stories of the week.

A vulnerability in the web-based management interface of Cisco IoT Control Center could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

Multiple vulnerabilities in Cisco Nexus Dashboard could allow an authenticated, local attacker to elevate privileges on an affected device. These vulnerabilities are due to insufficient input validation during CLI command execution on an affected device. An attacker could exploit these vulnerabilities by authenticating as the rescue-user and executing vulnerable CLI commands using a malicious payload. A successful exploit could allow the attacker to elevate privileges to root on an affected device.

A vulnerability in Cisco Nexus Dashboard could allow an authenticated, remote attacker to write arbitrary files on an affected device. This vulnerability is due to insufficient input validation in the web-based management interface of Cisco Nexus Dashboard. An attacker with Administrator credentials could exploit this vulnerability by uploading a crafted file. A successful exploit could allow the attacker to overwrite arbitrary files on an affected device.
