Jan 31, 2024 Vulnerability / Zero Day
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...
Telegram Marketplaces Fuel Phishing Attacks with Easy-to-Use Kits and Malware

Telegram Marketplaces Fuel Phishing Attacks with Easy-to-Use Kits and Malware

Jan 31, 2024 Cyber Crime / Hacking News
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 Won't Let CISOs Be: Understanding New SaaS Cybersecurity Rules

The SEC Won't Let CISOs Be: Understanding New SaaS Cybersecurity Rules

Jan 31, 2024 SaaS Security / Regulations
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...

Italian Businesses Hit by Weaponized USBs Spreading Cryptojacking Malware

Italian Businesses Hit by Weaponized USBs Spreading Cryptojacking Malware

Jan 31, 2024 Cryptocurrency / Cybersecurity
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 ...
Hackers Exploiting Ivanti VPN Flaws to Deploy KrustyLoader Malware

Hackers Exploiting Ivanti VPN Flaws to Deploy KrustyLoader Malware

Jan 31, 2024 Cyber Attack / Network Security
A pair of recently disclosed zero-day flaws in Ivanti Connect Secure (ICS) virtual private network (VPN) devices have been exploited to deliver a Rust-based payload called  KrustyLoader  that's used to drop the open-source Sliver adversary simulation tool. The  security vulnerabilities , tracked as CVE-2023-46805 (CVSS score: 8.2) and CVE-2024-21887 (CVSS score: 9.1), could be abused in tandem to achieve unauthenticated remote code execution on susceptible appliances. As of January 26,  patches for the two flaws  have been delayed, although the software company has released a temporary mitigation through an XML file. Volexity, which first shed light on the shortcomings, said they have been weaponized as zero-days since December 3, 2023, by a Chinese nation-state threat actor it tracks under the name UTA0178. Google-owned Mandiant has assigned the moniker UNC5221 to the group. Following public disclosure earlier this month, the vulnerabilities have  co...
New Glibc Flaw Grants Attackers Root Access on Major Linux Distros

New Glibc Flaw Grants Attackers Root Access on Major Linux Distros

Jan 31, 2024 Vulnerability / Endpoint Security
Malicious local attackers can obtain full root access on Linux machines by taking advantage of a newly disclosed security flaw in the GNU C library (aka glibc). Tracked as CVE-2023-6246 (CVSS score: 7.8), the heap-based buffer overflow vulnerability is rooted in glibc's __vsyslog_internal() function, which is used by  syslog() and vsyslog()  for system logging purposes. It's said to have been accidentally introduced in August 2022 with the release of glibc 2.37. "This flaw allows local privilege escalation, enabling an unprivileged user to gain full root access," Saeed Abbasi, product manager of the Threat Research Unit at Qualys,  said , adding it impacts major Linux distributions like Debian, Ubuntu, and Fedora. A threat actor could exploit the flaw to obtain elevated permissions via specially crafted inputs to applications that employ these logging functions. "Although the  vulnerability  requires specific conditions to be exploited (such as an unusual...
