A Russian-speaking ransomware outfit likely targeted an unnamed entity in the gambling and gaming sector in Europe and Central America by repurposing custom tools developed by other APT groups like Iran's MuddyWater, new research has found. The unusual attack chain involved the abuse of stolen credentials to gain unauthorized access to the victim network, ultimately leading to the deployment of Cobalt Strike payloads on compromised assets,  said  Felipe Duarte and Ido Naor, researchers at Israeli incident response firm Security Joes, in a report published last week. Although the infection was contained at this stage, the researchers characterized the compromise as a case of a suspected ransomware attack. The intrusion is said to have taken place in February 2022, with the attackers making use of post-exploitation tools such as  ADFind , NetScan,  SoftPerfect , and  LaZagne . Also employed is an AccountRestore executable to brute-force administrator credenti...

A newly disclosed security flaw in the Linux kernel could be leveraged by a local adversary to gain elevated privileges on vulnerable systems to execute arbitrary code, escape containers, or induce a  kernel panic . Tracked as  CVE-2022-25636  (CVSS score: 7.8), the vulnerability impacts Linux kernel versions 5.4 through 5.6.10 and is a result of a heap out-of-bounds write in the netfilter subcomponent in the kernel. The issue was  discovered  by Nick Gregory, a senior threat researcher at Sophos. "This flaw allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a privilege escalation threat," Red Hat  said  in an advisory published on February 22, 2022. Similar alerts have been released by  Debian ,  Oracle Linux ,  SUSE , and  Ubuntu . Netfilter is a  framework  provided by the Linux kernel that enables various networking-related operations, inc...

New findings released last week showcase the overlapping source code and techniques between the operators of  Shamoon  and  Kwampirs , indicating that they "are the same group or really close collaborators." "Research evidence shows identification of co-evolution between both Shamoon and Kwampirs malware families during the known timeline," Pablo Rincón Crespo of Cylera Labs  said . "If Kwampirs is based on the original Shamoon, and Shamoon 2 and 3 campaign code is based on Kwampirs, […] then the authors of Kwampirs would be potentially the same as the authors of Shamoon, or must have a very strong relationship, as has been seen over the course of many years," Rincón Crespo added. Shamoon, also known as DistTrack, functions as an information-stealing malware that also incorporates a destructive component that allows it to overwrite the Master Boot Record (MBR) with arbitrary data so as to render the infected machine inoperable. The malware, developed...

Multiple security vulnerabilities have been disclosed in popular package managers that, if potentially exploited, could be abused to run arbitrary code and access sensitive information, including source code and access tokens, from compromised machines. It's, however, worth noting that the flaws require the targeted developers to handle a malicious package in conjunction with one of the affected package managers. "This means that an attack cannot be launched directly against a developer machine from remote and requires that the developer is tricked into loading malformed files," SonarSource researcher Paul Gerste  said . "But can you always know and trust the owners of all packages that you use from the internet or company-internal repositories?" Package managers refer to  systems  or a set of tools that are used to automate installing, upgrading, configuring third-party dependencies required for developing applications. While there are inherent  security ...

The Russian government has established its own TLS certificate authority ( CA ) to address issues with accessing websites that have arisen in the wake of sanctions imposed by the west following the country's unprovoked military invasion of Ukraine. According to a message posted on the  Gosuslugi  public services portal, the Ministry of Digital Development is expected to provide a domestic replacement to handle the issuance and renewal of TLS certificates should they get revoked or expired. The service is offered to all legal entities operating in Russia, with the certificates delivered to site owners upon request within 5 working days. TLS certificates are used to digitally bind a cryptographic key to an organization's details, enabling web browsers to confirm the domain's authenticity and ensure that the communication between a client computer and the target website is secure. The proposal comes as companies like DigiCert have been restricted from doing business in ...
