| Salt Typhoon Breached AT&T, Verizon, and Lumen Networks: A Chinese nation-state actor known as Salt Typhoon penetrated the networks of U.S. broadband providers, including AT&T, Verizon, and Lumen, and likely accessed "information from systems the federal government uses for court-authorized network wiretapping requests," The Wall Street Journal reported. "The hackers appear to have engaged in a vast collection of internet traffic from internet service providers that count businesses large and small, and millions of Americans, as their customers." U.K. and U.S. Warn of Iranian Spear-Phishing Activity: Cyber actors working on behalf of the Iranian Government's Islamic Revolutionary Guard Corps (IRGC) have targeted individuals with a nexus to Iranian and Middle Eastern affairs to gain unauthorized access to their personal and business accounts using social engineering techniques, either via email or messaging platforms. "The actors often attempt to build rapport before soliciting victims to access a document via a hyperlink, which redirects victims to a false email account login page for the purpose of capturing credentials," the agencies said in an advisory. "Victims may be prompted to input two-factor authentication codes, provide them via a messaging application, or interact with phone notifications to permit access to the cyber actors." NIST NVD Backlog Crisis - 18,000+ CVEs Unanalyzed: A new analysis has revealed that the National Institute of Standards and Technology (NIST), the U.S. government standards body, has still a long way to go in terms of analyzing newly published CVEs. As of September 21, 2024, 72.4% of CVEs (18,358 CVEs) in the NVD have yet to be analyzed, VulnCheck said, adding "46.7% of Known Exploited Vulnerabilities (KEVs) remain unanalyzed by the NVD (compared to 50.8% as of May 19, 2024)." It's worth noting that a total of 25,357 new vulnerabilities have been added to NVD since February 12, 2024, when NIST scaled back its processing and enrichment of new vulnerabilities. Major RPKI Flaws Uncovered in BGP's Cryptographic Defense: A group of German researchers has found that current implementations of Resource Public Key Infrastructure (RPKI), which was introduced as a way to introduce a cryptographic layer to Border Gateway Protocol (BGP), "lack production-grade resilience and are plagued by software vulnerabilities, inconsistent specifications, and operational challenges." These vulnerabilities range from denial-of-service and authentication bypass to cache poisoning and remote code execution. Telegram's Data Policy Shift Pushes Cybercriminals to Alternative Apps: Telegram's recent decision to give users' IP addresses and phone numbers to authorities in response to valid legal requests is prompting cybercrime groups to seek other alternatives to the messaging app, including Jabber, Tox, Matrix, Signal, and Session. The Bl00dy ransomware gang has declared that it's "quitting Telegram," while hacktivist groups like Al Ahad, Moroccan Cyber Aliens, and RipperSec have expressed an intent to move to Signal and Discord. That said, neither Signal nor Session support bot functionality or APIs like Telegram nor do they have extensive group messaging capabilities. Jabber and Tox, on the other hand, have already been used by adversaries operating on underground forums. "Telegram's expansive global user base still provides extensive reach, which is crucial for cybercriminal activities such as disseminating information, recruiting associates or selling illicit goods and services," Intel 471 said. Telegram CEO Pavel Durov, however, has downplayed the changes, stating "little has changed" and that it has been sharing data with law enforcement since 2018 in response to valid legal requests. "For example, in Brazil, we disclosed data for 75 legal requests in Q1 (January-March) 2024, 63 in Q2, and 65 in Q3. In India, our largest market, we satisfied 2461 legal requests in Q1, 2151 in Q2, and 2380 in Q3," Durov added.
