REvil, the infamous ransomware cartel behind some of the biggest cyberattacks targeting JBS and Kaseya, has mysteriously disappeared from the dark web, leading to speculations that the criminal enterprise may have been taken down. Multiple darknet and clearnet sites maintained by the Russia-linked cybercrime syndicate, including the data leak, extortion, and payment portals, remained inaccessible, displaying an error message "Onionsite not found."  The group's  Tor network infrastructure  on the dark web consists of one data leak blog site and 22 data hosting sites. It's not immediately clear what prompted the infrastructure to be knocked offline. REvil is one of the most prolific ransomware-as-a-service (RaaS) groups that first appeared on the threat landscape in April 2019. It's an evolution of the  GandCrab  ransomware, which hit the underground markets in early 2018. "If REvil has been permanently disrupted, it'll mark the end of a group which ha...

Microsoft rolled out  Patch Tuesday updates  for the month of July with fixes for a total of 117 security vulnerabilities, including nine zero-day flaws, of which four are said to be under active attacks in the wild, potentially enabling an adversary to take control of affected systems.  Of the 117 issues, 13 are rated Critical, 103 are rated Important, and one is rated as Moderate in severity, with six of these bugs publicly known at the time of release.  The updates span across several of Microsoft's products, including Windows, Bing, Dynamics, Exchange Server, Office, Scripting Engine, Windows DNS, and Visual Studio Code. July also marks a dramatic jump in the volume of vulnerabilities, surpassing the number Microsoft collectively addressed as part of its updates in  May  (55) and  June  (50). Chief among the security flaws actively exploited are as follows — CVE-2021-34527  (CVSS score: 8.8) - Windows Print Spooler Remote Code Exec...

Microsoft on Tuesday disclosed that the latest string of attacks targeting SolarWinds Serv-U managed file transfer service with a now-patched remote code execution (RCE) exploit is the handiwork of a Chinese threat actor dubbed "DEV-0322." The revelation comes days after the Texas-based IT monitoring software maker issued fixes for the flaw that could enable adversaries to remotely run arbitrary code with privileges, allowing them to perform actions like install and run malicious payloads or view and alter sensitive data. Tracked as  CVE-2021-35211 , the RCE flaw resides in Serv-U's implementation of the Secure Shell (SSH) protocol. While it was previously revealed that the attacks were limited in scope, SolarWinds said it's "unaware of the identity of the potentially affected customers." Attributing the intrusions with high confidence to DEV-0322 (short for "Development Group 0322") based on observed victimology, tactics, and procedures, Micr...

Cybersecurity researchers have disclosed new security vulnerabilities in the Etherpad text editor (version 1.8.13) that could potentially enable attackers to hijack administrator accounts, execute system commands, and even steal sensitive documents. The two flaws — tracked as CVE-2021-34816 and CVE-2021-34817 — were discovered and reported on June 4 by researchers from SonarSource, following which patches have been shipped for the latter in  version 1.8.14  of Etherpad released on July 4. Etherpad is a real-time collaborative interface that enables a document to be edited simultaneously by multiple authors. It is an open-source alternative to Google Docs that can be self-hosted or used through one of the many third-party public instances available. "The XSS vulnerability allows attackers to take over Etherpad users, including admins. This can be used to steal or manipulate sensitive data," SonarSource vulnerability researcher Paul Gerste  said  in a report shar...

A sophisticated social engineering attack undertaken by an Iranian-state aligned actor targeted think tanks, journalists, and professors with an aim to solicit sensitive information by masquerading as scholars with the University of London's School of Oriental and African Studies (SOAS). Enterprise security firm Proofpoint attributed the campaign — called " Operation SpoofedScholars " — to the advanced persistent threat tracked as  TA453 , which is also known by the aliases APT35 (FireEye), Charming Kitten (ClearSky), and Phosphorous (Microsoft). The government cyber warfare group is suspected to carry out intelligence efforts on behalf of the Islamic Revolutionary Guard Corps (IRGC). "Identified targets included experts in Middle Eastern affairs from think tanks, senior professors from well-known academic institutions, and journalists specializing in Middle Eastern coverage," the researchers said in a technical write-up shared with The Hacker News. "T...

Cybersecurity researchers have opened the lid on the continued resurgence of the insidious Trickbot malware , making it clear that the Russia-based transnational cybercrime group is working behind the scenes to revamp its attack infrastructure in response to recent counter efforts from law enforcement. "The new capabilities discovered are used to monitor and gather intelligence on victims, using a custom communication protocol to hide data transmissions between [command-and-control] servers and victims — making attacks difficult to spot," Bitdefender  said  in a technical write-up published Monday, suggesting an increase in sophistication of the group's tactics. "Trickbot shows no sign of slowing down," the researchers noted. Botnets are formed when hundreds or thousands of hacked devices are enlisted into a network run by criminal operators, which are often then used to launch denial-of-network attacks to pummel businesses and critical infrastructure with ...

Cybersecurity agencies in Australia and the U.S. are  warning  of an actively exploited vulnerability impacting ForgeRock's OpenAM access management solution that could be leveraged to execute arbitrary code on an affected system remotely. "The [Australian Cyber Security Centre] has observed actors exploiting this vulnerability to compromise multiple hosts and deploy additional malware and tools," the organization  said  in an alert. ACSC didn't disclose the nature of the attacks, how widespread they are, or the identities of the threat actors exploiting them. Tracked as  CVE-2021-35464 , the issue concerns a pre-authentication remote code execution (RCE) vulnerability in ForgeRock Access Manager identity and access management tool, and stems from an  unsafe Java deserialization  in the Jato framework used by the software. "An attacker exploiting the vulnerability will execute commands in the context of the current user, not as the root user (unl...
