gRPC contains a vulnerability that allows hpack table accounting errors could lead to unwanted disconnects between clients and servers in exceptional cases/ Three vectors were found that allow the following DOS attacks: - Unbounded memory buffering in the HPACK parser - Unbounded CPU consumption in the HPACK parser The unbounded CPU consumption is down to a copy that occurred per-input-block in the parser, and because that could be unbounded due to the memory copy bug we end up with an O(n^2) parsing loop, with n selected by the client. The unbounded memory buffering bugs: - The header size limit check was behind the string reading code, so we needed to first buffer up to a 4 gigabyte string before rejecting it as longer than 8 or 16kb. - HPACK varints have an encoding quirk whereby an infinite number of 0’s can be added at the start of an integer. gRPC’s hpack parser needed to read all of them before concluding a parse. - gRPC’s metadata overflow check was performed per frame, so ...

Ransomware and pre-ransomware engagements make up 40 percent of threats seen this quarter By Caitlin Huey. For the first time since compiling these reports, Cisco Talos Incident Response saw an equal number of ransomware and pre-ransomware engagements, making up nearly 40 percent of threats this quarter.   It can be difficult to determine what constitutes a pre-ransomware attack if ransomware never executes and encryption does not take place. However, Talos IR assesses that the combination of Cobalt Strike and credential-harvesting tools like Mimikatz, paired with enumeration and discovery techniques, indicates a high likelihood that ransomware is the final objective. This quarter featured a variety of publicly available tools and scripts hosted on GitHub repositories or other third-party websites to support operations across multiple stages of the attack lifecycle. This activity coincides with a general increase in the use of other dual-use tools, such as the legitimate red-teaming ...

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...

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 ...

A large software development company whose software is used by different state entities in Ukraine was at the receiving end of an "uncommon" piece of malware, new research has found.

Executive summary Since the Russian invasion of Ukraine began, Ukrainians have been under a nearly constant barrage of cyber attacks. Working jointly with Ukrainian organizations, Cisco Talos has discovered a fairly uncommon piece of malware targeting Ukraine — this time aimed at a large software development company whose software is used in various state organizations within Ukraine. We believe that this campaign is likely sourced by Russian state-sponsored actors or those acting in their interests. As this firm is involved in software development, we cannot ignore the possibility that the perpetrating threat actor's intent was to gain access to source a supply chain-style attack, though at this time we do not have any evidence that they were successful. Cisco Talos confirmed that the malware is a slightly modified version of the open-source backdoor named "GoMet." The malware was first observed on March 28, 2022.

Versions of the Amazon AWS Apache Log4j hotpatch package before log4j-cve-2021-44228-hotpatch-1.3.5 are affected by a race condition that could lead to a local privilege escalation. This Hotpatch package is not a replacement for updating to a log4j version that mitigates CVE-2021-44228 or CVE-2021-45046; it provides a temporary mitigation to CVE-2021-44228 by hotpatching the local Java virtual machines. To do so, it iterates through all running Java processes, performs several checks, and executes the Java virtual machine with the same permissions and capabilities as the running process to load the hotpatch. A local user could cause the hotpatch script to execute a binary with elevated privileges by running a custom java process that performs exec() of an SUID binary after the hotpatch has observed the process path and before it has observed its effective user ID.

We have been actively working with customers through our customer support teams, third-party hosters, and partner network to help them secure their environments and respond to associated threats from the recent Exchange Server on-premises attacks. Based on these engagements we realized that there was a need for a simple, easy to use, automated solution that would meet the needs of customers using both current and out-of-support versions of on-premises Exchange Server.

Update March 15, 2021: If you have not yet patched, and have not applied the mitigations referenced below, a one-click tool, the Exchange On-premises Mitigation Tool is now our recommended path to mitigate until you can patch. Microsoft previously blogged our strong recommendation that customers upgrade their on-premises Exchange environments to the latest supported version.

Microsoft Exchange Server Remote Code Execution Vulnerability This CVE ID is unique from CVE-2021-26412, CVE-2021-26854, CVE-2021-26855, CVE-2021-26857, CVE-2021-26858, CVE-2021-27078.

On March 2nd, we released several security updates for Microsoft Exchange Server to address vulnerabilities that are being used in ongoing attacks. Due to the critical nature of these vulnerabilities, we recommend that customers protect their organizations by applying the patches immediately to affected systems. The vulnerabilities affect Exchange Server versions 2013, 2016, and 2019, while Exchange Server 2010 is also being updated for defense-in-depth purposes.

Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.

In Pulse Secure Pulse Connect Secure version 9.0RX before 9.0R3.4, 8.3RX before 8.3R7.1, and 8.2RX before 8.2R12.1, users using SAML authentication with the Reuse Existing NC (Pulse) Session option may see authentication leaks.

Remote code execution is possible with Apache Tomcat before 6.0.48, 7.x before 7.0.73, 8.x before 8.0.39, 8.5.x before 8.5.7, and 9.x before 9.0.0.M12 if JmxRemoteLifecycleListener is used and an attacker can reach JMX ports. The issue exists because this listener wasn't updated for consistency with the CVE-2016-3427 Oracle patch that affected credential types.
