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 ...

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...

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...

A Brazilian law enforcement operation has led to the arrest of several Brazilian operators in charge of the  Grandoreiro  malware. The Federal Police of Brazil  said  it served five temporary arrest warrants and 13 search and seizure warrants in the states of São Paulo, Santa Catarina, Pará, Goiás, and Mato Grosso. Slovak cybersecurity firm ESET, which provided additional assistance in the effort, said it uncovered a design flaw in Grandoreiro's network protocol that helped it to identify the victimology patterns. Grandoreiro  is one of the many Latin American banking trojans such as Javali, Melcoz, Casabeniero, Mekotio, and Vadokrist, primarily targeting countries like Spain, Mexico, Brazil, and Argentina. It's known to be active since 2017. In late October 2023, Proofpoint  revealed  details of a phishing campaign that distributed an updated version of the malware to targets in Mexico and Spain. The banking trojan has capabilities to both stea...

GitLab once again released fixes to address a critical security flaw in its Community Edition (CE) and Enterprise Edition (EE) that could be exploited to write arbitrary files while creating a  workspace . Tracked as  CVE-2024-0402 , the vulnerability has a CVSS score of 9.9 out of a maximum of 10. "An issue has been discovered in GitLab CE/EE affecting all versions from 16.0 prior to 16.5.8, 16.6 prior to 16.6.6, 16.7 prior to 16.7.4, and 16.8 prior to 16.8.1 which allows an authenticated user to write files to arbitrary locations on the GitLab server while creating a workspace," GitLab  said  in an advisory released on January 25, 2024. The company also noted patches for the bug have been backported to 16.5.8, 16.6.6, 16.7.4, and 16.8.1. Also resolved by GitLab are four medium-severity flaws that could lead to a regular expression denial-of-service (ReDoS), HTML injection, and the disclosure of a user's public email address via the tags RSS feed.
