Google-owned Mandiant said it identified new malware employed by a China-nexus espionage threat actor known as UNC5221 and other threat groups during post-exploitation activity targeting Ivanti Connect Secure VPN and Policy Secure devices. This includes custom web shells such as BUSHWALK, CHAINLINE, FRAMESTING, and a variant of  LIGHTWIRE . "CHAINLINE is a Python web shell backdoor that is embedded in a Ivanti Connect Secure Python package that enables arbitrary command execution," the company  said , attributing it to UNC5221, adding it also detected multiple new versions of  WARPWIRE , a JavaScript-based credential stealer. The infection chains entail a successful exploitation of  CVE-2023-46805 and CVE-2024-21887 , which allow an unauthenticated threat actor to execute arbitrary commands on the Ivanti appliance with elevated privileges. The flaws have been abused as zero-days since early December 2023. Germany's Federal Office for Information Security (BSI)...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday  added  a high-severity flaw impacting iOS, iPadOS, macOS, tvOS, and watchOS to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability, tracked as  CVE-2022-48618  (CVSS score: 7.8), concerns a bug in the kernel component. "An attacker with arbitrary read and write capability may be able to bypass  Pointer Authentication ," Apple said in an advisory, adding the issue "may have been exploited against versions of iOS released before iOS 15.7.1." The iPhone maker said the problem was addressed with improved checks. It's currently not known how the vulnerability is being weaponized in real-world attacks. Interestingly, patches for the flaw were released on December 13, 2022, with the release of  iOS 16.2, iPadOS 16.2 ,  macOS Ventura 13.1 ,  tvOS 16.2 , and  watchOS 9.2 , although it was only publicly discl...

Multiple security vulnerabilities have been disclosed in the runC command line tool that could be exploited by threat actors to escape the bounds of the container and stage follow-on attacks. The vulnerabilities, tracked as CVE-2024-21626, CVE-2024-23651, CVE-2024-23652, and CVE-2024-23653, have been collectively dubbed  Leaky Vessels  by cybersecurity vendor Snyk. "These container escapes could allow an attacker to gain unauthorized access to the underlying host operating system from within the container and potentially permit access to sensitive data (credentials, customer info, etc.), and launch further attacks, especially when the access gained includes superuser privileges," the company  said  in a report shared with The Hacker News. runC  is a tool for spawning and running containers on Linux. It was originally developed as part of Docker and later  spun out  into a separate open-source library in 2015. A brief description of each of the fl...

Ivanti is alerting of two new high-severity flaws in its Connect Secure and Policy Secure products, one of which is said to have come under targeted exploitation in the wild. The list of vulnerabilities is as follows - CVE-2024-21888  (CVSS score: 8.8) - A privilege escalation vulnerability in the web component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure (9.x, 22.x) allows a user to elevate privileges to that of an administrator CVE-2024-21893  (CVSS score: 8.2) - A server-side request forgery vulnerability in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x) and Ivanti Neurons for ZTA allows an attacker to access certain restricted resources without authentication The Utah-based software company  said  it found no evidence of customers being impacted by CVE-2024-21888 so far, but acknowledged "the exploitation of CVE-2024-21893 appears to be targeted" and that it's "aware of a limited number of cust...

Cybersecurity researchers are calling attention to the "democratization" of the phishing ecosystem owing to the emergence of Telegram as an epicenter for cybercrime, enabling threat actors to mount a mass attack for as little as $230. "This messaging app has transformed into a bustling hub where seasoned cybercriminals and newcomers alike exchange illicit tools and insights creating a dark and well-oiled supply chain of tools and victims' data," Guardio Labs researchers Oleg Zaytsev and Nati Tal  said  in a new report. "Free samples, tutorials, kits, even hackers-for-hire – everything needed to construct a complete end-to-end malicious campaign." The company also described Telegram as a "scammers paradise" and a "breeding ground for modern phishing operations." This is not the first time the popular messaging platform has  come under the radar  for facilitating malicious activities, which are in part driven by its lenient modera...

The SEC isn't giving SaaS a free pass. Applicable public companies, known as "registrants," are now subject to cyber incident disclosure and cybersecurity readiness requirements for data stored in SaaS systems, along with the 3rd and 4th party apps connected to them.  The new cybersecurity mandates  make no distinction between data exposed in a breach that was stored on-premise, in the cloud, or in SaaS environments. In the SEC's own words: "We do not believe that a reasonable investor would view a significant data breach as immaterial merely because the data are housed on a cloud service." This evolving approach comes as SaaS security shortcomings continually make headlines and tech leaders debate  how the SEC may change cybersecurity  after charging both SolarWinds and its CISO with fraud.  Why SaaS and SaaS-to-SaaS Connection Risks Matter to the SEC — And To Your Organization  The perception and reality of SaaS security are, in many cases, miles apa...

A financially motivated threat actor known as  UNC4990  is leveraging weaponized USB devices as an initial infection vector to target organizations in Italy. Google-owned Mandiant said the attacks single out multiple industries, including health, transportation, construction, and logistics. "UNC4990 operations generally involve widespread USB infection followed by the deployment of the EMPTYSPACE downloader," the company  said  in a Tuesday report. "During these operations, the cluster relies on third-party websites such as GitHub, Vimeo, and Ars Technica to host encoded additional stages, which it downloads and decodes via PowerShell early in the execution chain." UNC4990, active since late 2020, is assessed to be operating out of Italy based on the extensive use of Italian infrastructure for command-and-control (C2) purposes. It's currently not known if UNC4990 functions only as an initial access facilitator for other actors. The end goal of the threat ...
