Romanian cybersecurity company Bitdefender has released a free decryptor to help victims recover data encrypted using the ShrinkLocker ransomware. The decryptor is the result of a comprehensive analysis of ShrinkLocker's inner workings, allowing the researchers to discover a "specific window of opportunity for data recovery immediately after the removal of protectors from BitLocker-encrypted disks." ShrinkLocker was first documented in May 2024 by Kaspersky, which found the malware's use of Microsoft's native BitLocker utility for encrypting files as part of extortion attacks targeting Mexico, Indonesia, and Jordan. It appears to have been adapted from benign ten-year-old code. Bitdefender, which investigated a ShrinkLocker incident targeting an unnamed healthcare company in the Middle East, said the attack likely originated from a machine belonging to a contractor, once again highlighting how threat actors are increasingly abusing trusted relationships to ...

The rise of SaaS and cloud-based work environments has fundamentally altered the cyber risk landscape. With more than 90% of organizational network traffic flowing through browsers and web applications, companies are facing new and serious cybersecurity threats. These include phishing attacks, data leakage, and malicious extensions. As a result, the browser also becomes a vulnerability that needs to be protected. LayerX has released a comprehensive guide titled "Kickstarting Your Browser Security Program” This in-depth guide serves as a roadmap for CISOs and security teams looking to secure browser activities within their organization; including step-by-step instructions, frameworks, and use cases. Below, we bring its main highlights. Prioritizing Browser Security Browsers now serve as the primary interface for SaaS applications, creating new malicious opportunities for cyber adversaries. The risks include: Data leakage - Browsers can expose sensitive data by allowing empl...

A security analysis of the OvrC cloud platform has uncovered 10 vulnerabilities that could be chained to allow potential attackers to execute code remotely on connected devices. "Attackers successfully exploiting these vulnerabilities can access, control, and disrupt devices supported by OvrC; some of those include smart electrical power supplies, cameras, routers, home automation systems, and more," Claroty researcher Uri Katz said in a technical report. Snap One's OvrC, pronounced "oversee," is advertised as a "revolutionary support platform" that enables homeowners and businesses to remotely manage, configure, and troubleshoot IoT devices on the network. According to its website, OvrC solutions are deployed at over 500,000 end-user locations. According to a coordinated advisory issued by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), successful exploitation of the identified vulnerabilities could allow an attacker to ...

The Iranian threat actor known as TA455 has been observed taking a leaf out of a North Korean hacking group's playbook to orchestrate its own version of the Dream Job campaign targeting the aerospace industry by offering fake jobs since at least September 2023. "The campaign distributed the SnailResin malware, which activates the SlugResin backdoor," Israeli cybersecurity company ClearSky said in a Tuesday analysis. TA455, also tracked by Google-owned Mandiant as UNC1549 and by PwC as Yellow Dev 13, is assessed to be a sub-cluster within APT35 , which is known by the names CALANQUE, Charming Kitten, CharmingCypress, ITG18, Mint Sandstorm (formerly Phosphorus), Newscaster, TA453, and Yellow Garuda. Affiliated with Iran's Islamic Revolutionary Guard Corps (IRGC), the group is said to share tactical overlaps with clusters referred to as Smoke Sandstorm (previously Bohrium) and Crimson Sandstorm (previously Curium). Earlier this February, the adversarial collecti...

Microsoft on Tuesday revealed that two security flaws impacting Windows NT LAN Manager ( NTLM ) and Task Scheduler have come under active exploitation in the wild. The security vulnerabilities are among the 90 security bugs the tech giant addressed as part of its Patch Tuesday update for November 2024. Of the 90 flaws, four are rated Critical, 85 are rated Important, and one is rated Moderate in severity. Fifty-two of the patched vulnerabilities are remote code execution flaws. The fixes are in addition to 31 vulnerabilities Microsoft resolved in its Chromium-based Edge browser since the release of the October 2024 Patch Tuesday update. The two vulnerabilities that have been listed as actively exploited are below - CVE-2024-43451 (CVSS score: 6.5) - Windows NTLM Hash Disclosure Spoofing Vulnerability CVE-2024-49039 (CVSS score: 8.8) - Windows Task Scheduler Elevation of Privilege Vulnerability "This vulnerability discloses a user's NTLMv2 hash to the attacker who c...
