Cisco on Wednesday rolled out patches for  10 security flaws  spanning multiple products, one of which is rated Critical in severity and could be weaponized to conduct absolute path traversal attacks. The issues, tracked as  CVE-2022-20812 and CVE-2022-20813 , affect Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) and "could allow a remote attacker to overwrite arbitrary files or conduct null byte poisoning attacks on an affected device," the company  said  in an advisory. CVE-2022-20812 (CVSS score: 9.0), which concerns a case of arbitrary file overwrite in the cluster database API, requires the authenticated, remote attacker to have Administrator read-write privileges on the application so as to be able to mount path traversal attacks as a root user. "This vulnerability is due to insufficient input validation of user-supplied command arguments," the company said. "An attacker could exploit this vulnerability by authenticati...

The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has  chosen  the first set of quantum-resistant encryption algorithms that are designed to "withstand the assault of a future quantum computer." The post-quantum cryptography ( PQC ) technologies include the  CRYSTALS-Kyber  algorithm for general encryption, and  CRYSTALS-Dilithium ,  FALCON , and  SPHINCS+  for digital signatures. "Three of the selected algorithms are based on a family of math problems called structured lattices, while SPHINCS+ uses hash functions," NIST, which kicked off the standardization process in January 2017,  said  in a statement. Cryptography, which underpins the security of information in modern computer networks, derives its strength from the difficulty of solving mathematical problems — e.g., factoring large composite integers — using traditional computers. Quantum computers, should they mature enough, pose a  ...

The maintainers of the OpenSSL project have released patches to address a  high-severity bug  in the cryptographic library that could potentially lead to remote code execution under certain scenarios. The  issue , now assigned the identifier  CVE-2022-2274 , has been described as a case of heap memory corruption with RSA private key operation that was introduced in OpenSSL version 3.0.4 released on June 21, 2022. First released in 1998, OpenSSL is a general-purpose  cryptography library  that offers open-source implementation of the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, enabling users to generate private keys, create certificate signing requests ( CSRs ), install SSL/TLS certificates. "SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue," the advisory  noted . Calling it a "serious bug in the...

Malicious actors have been observed abusing legitimate adversary simulation software in their attacks in an attempt to stay under the radar and evade detection. Palo Alto Networks Unit 42 said a  malware sample  uploaded to the VirusTotal database on May 19, 2022, contained a payload associated with Brute Ratel C4, a relatively new sophisticated toolkit "designed to avoid detection by endpoint detection and response (EDR) and antivirus (AV) capabilities." Authored by an Indian security researcher named  Chetan Nayak , Brute Ratel (BRc4) is analogous to Cobalt Strike and is  described  as a "customized command-and-control center for red team and adversary simulation." The commercial software was first released in late 2020 and has since gained over 480 licenses across 350 customers. Each license is offered at $2,500 per user for a year, after which it can be renewed for the same duration at the cost of $2,250. BRc4 is equipped with a wide variety of featur...

July may positively disrupt and adrenalize the old-fashioned Dynamic Application Security Scanning (DAST) market, despite the coming holiday season. The pathbreaking innovation comes from ImmuniWeb, a global application security company, well known for, among other things, its free  Community Edition  that processes over 100,000 daily security scans of web and mobile apps.  Today, ImmuniWeb announced that its new product –  Neuron  – is publicly available. This would be another boring press release by a software vendor, but the folks from ImmuniWeb managed to add a secret sauce that you will unlikely be able to resist tasting. The DAST scanning service is flexibly available as a SaaS, and unsurprisingly contains all fashionable features commonly advertised by competitors on the rapidly growing global market, spanning from native CI/CD integrations to advanced configuration of security scanning, pre-programmed or authenticated testing.  But the groundbrea...

Military entities located in Bangladesh continue to be at the receiving end of sustained cyberattacks by an advanced persistent threat tracked as Bitter. "Through malicious document files and intermediate malware stages the threat actors conduct espionage by deploying Remote Access Trojans," cybersecurity firm SECUINFRA  said  in a new write-up published on July 5. The findings from the Berlin-headquartered company build on a  previous report  from Cisco Talos in May, which disclosed the group's expansion in targeting to strike Bangladeshi government organizations with a backdoor called  ZxxZ . Bitter, also tracked under the codenames APT-C-08 and T-APT-17, is said to be active  since at least late 2013  and has a track record of targeting China, Pakistan, and Saudi Arabia using different tools such as BitterRAT and ArtraDownloader. The latest attack chain detailed by SECUINFRA is believed to have been conducted in mid-May 2022, originating with...

The operators of the Hive ransomware-as-a-service (RaaS) scheme have overhauled their file-encrypting software to fully migrate to Rust and adopt a more sophisticated encryption method. "With its latest variant carrying several major upgrades, Hive also proves it's one of the fastest evolving ransomware families, exemplifying the continuously changing ransomware ecosystem," Microsoft Threat Intelligence Center (MSTIC)  said  in a report on Tuesday. Hive , which was first observed in June 2021, has emerged as one of the most prolific RaaS groups,  accounting  for 17 attacks in the month of May 2022 alone, alongside  Black Basta and Conti . The shift from GoLang to Rust makes Hive the second ransomware strain after  BlackCat  to be written in the programming language, enabling the malware to gain additional benefits such as memory safety and deeper control over low-level resources as well as make use of a wide range of cryptographic libraries. What...
