The Computer Emergency Response Team of Ukraine (CERT-UA) on Tuesday  disclosed  that it thwarted a cyberattack by Sandworm , a hacking group affiliated with Russia's military intelligence, to sabotage the operations of an unnamed energy provider in the country. "The attackers attempted to take down several infrastructure components of their target, namely: Electrical substations, Windows-operated computing systems, Linux-operated server equipment, [and] active network equipment," the State Service of Special Communications and Information Protection of Ukraine (SSSCIP)  said  in a statement. Slovak cybersecurity firm ESET, which collaborated with CERT-UA to analyze the attack, said the attempted intrusion involved the use of ICS-capable malware and regular disk wipers, with the adversary unleashing an updated variant of the  Industroyer  malware, which was first deployed in a 2016 assault on Ukraine's power grid. "The Sandworm attackers made an attemp...

An international law enforcement operation raided and took down RaidForums, one of the world's largest hacking forums notorious for selling access to hacked personal information belonging to users. Dubbed Tourniquet, the seizure of the cybercrime website involved authorities from the U.S., U.K., Sweden, Portugal, and Romania, with the criminal investigation resulting in the  arrest  of the forum's administrator at his home last month in Croydon, England. The three confiscated domains associated with the illicit marketplace include "raidforums[.]com," "Rf[.]ws," and "Raid[.]lol." Diogo Santos Coelho (aka "Omnipotent"), the said founder and chief administrator, was apprehended in the U.K. on January 31 and is pending extradition to the U.S. Santos Coelho has been charged with conspiracy, access device fraud, and aggravated identity theft. In addition to detailing Santos Coelho's central role in designing and administering the soft...

Microsoft's Patch Tuesday updates for the month of April have addressed a  total of 128 security vulnerabilities  spanning across its software product portfolio, including Windows, Defender, Office, Exchange Server, Visual Studio, and Print Spooler, among others. 10 of the 128 bugs fixed are rated Critical, 115 are rated Important, and three are rated Moderate in severity, with one of the flaws listed as publicly known and another under active attack at the time of the release. The updates are in addition to  26 other flaws  resolved by Microsoft in its Chromium-based Edge browser since the start of the month. The actively exploited flaw ( CVE-2022-24521 , CVSS score: 7.8) relates to an elevation of privilege vulnerability in the Windows Common Log File System (CLFS). Credited with reporting the flaw are the U.S. National Security Agency (NSA) and CrowdStrike researchers Adam Podlosky and Amir Bazine. The second publicly-known zero-day flaw ( CVE-2022-26904 , C...

Unsurprisingly, here at  Rewind , we've got a lot of data to protect (over 2 petabytes worth). One of the databases we use is called Elasticsearch (ES or Opensearch, as it is currently known in AWS). To put it simply, ES is a document database that facilitates lightning-fast search results. Speed is essential when customers are looking for a particular file or item that they need to restore using  Rewind . Every second of downtime counts, so our search results need to be fast, accurate, and reliable. Another consideration was disaster  recovery . As part of our  System and Organization Controls Level 2 (SOC2)  certification process, we needed to ensure we had a working disaster recovery plan to restore service in the unlikely event that the entire AWS region was down. "An entire AWS region?? That will never happen!" (Except for  when it did )  Anything is possible, things go wrong, and in order to meet our SOC2 requirements we needed to have a work...

Researchers have disclosed a previously undocumented local file inclusion ( LFI ) vulnerability in  Hashnode , a developer-oriented blogging platform, that could be abused to access sensitive data such as SSH keys, server's IP address, and other network information. "The LFI originates in a  Bulk Markdown Import feature  that can be manipulated to provide attackers with unimpeded ability to download local files from Hashnode's server," Akamai researchers said in a report shared with The Hacker News. Local file inclusion flaws occur when a web application is tricked into exposing or running unapproved files on a server, leading to directory traversal, information disclosure, remote code execution, and cross-site scripting (XSS) attacks. The flaw, caused due to the web application failing to adequately sanitize the path to a file that's passed as input, could have serious repercussions in that an assailant could navigate to any path on the server and access s...
