Cybersecurity researchers have warned about a Windows version of a wiper malware that was previously observed targeting Linux systems in cyber attacks aimed at Israel. Dubbed  BiBi-Windows Wiper  by BlackBerry, the wiper is the Windows counterpart of  BiBi-Linux Wiper , which has been put to use by a pro-Hamas hacktivist group in the wake of the Israel-Hamas war last month. "The Windows variant [...] confirms that the threat actors who created the wiper are continuing to build out the malware, and indicates an expansion of the attack to target end user machines and application servers," the Canadian company  said  Friday. Slovak cybersecurity firm ESET is  tracking  the actor behind the wiper under the name BiBiGun, noting that the Windows variant (bibi.exe) is designed to overwrite data in the C:\Users directory recursively with junk data and append ".BiBi" to the filename. The BiBi-Windows Wiper artifact is said to have been compiled on October...

A sub-cluster within the infamous Lazarus Group has established new infrastructure that impersonates skills assessment portals as part of its social engineering campaigns. Microsoft attributed the activity to a threat actor it calls  Sapphire Sleet , describing it as a "shift in the persistent actor's tactics." Sapphire Sleet, also called APT38, BlueNoroff, CageyChameleon, and CryptoCore, has a track record of orchestrating cryptocurrency theft via social engineering. Earlier this week, Jamf Threat Labs implicated the threat actor to a new macOS malware family called  ObjCShellz  that's assessed to be a late-stage payload delivered in connection with another macOS malware known as RustBucket. "Sapphire Sleet typically finds targets on platforms like LinkedIn and uses lures related to skills assessment," the Microsoft Threat Intelligence team  said  in a series of posts on X (formerly Twitter). "The threat actor then moves successful communication...

The notorious Russian hackers known as  Sandworm  targeted an electrical substation in Ukraine last year, causing a brief power outage in October 2022. The findings come from Google's Mandiant, which described the hack as a "multi-event cyber attack" leveraging a novel technique for impacting industrial control systems (ICS). "The actor first used OT-level living-off-the-land ( LotL ) techniques to likely trip the victim's substation circuit breakers, causing an unplanned power outage that coincided with mass missile strikes on critical infrastructure across Ukraine," the company  said . "Sandworm later conducted a second disruptive event by deploying a new variant of  CaddyWiper  in the victim's IT environment." The threat intelligence firm did not reveal the location of the targeted energy facility, the duration of the blackout, and the number of people who were impacted by the incident. The development marks Sandworm's  continuous...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

There is a seemingly never-ending quest to find the right security tools that offer the right capabilities for your organization. SOC teams tend to spend about a  third of their day  on events that don't pose any threat to their organization, and this has accelerated the adoption of automated solutions to take the place of (or augment) inefficient and cumbersome SIEMs. With an estimated  80% of these threats  being common across most organizations, today's SOCs are able to confidently rely on automation to cover this large percentage of threat signals.  But, while it is true that automation can greatly improve the efficiency and effectiveness of security teams, it will never be able to cover all detection and response use cases infallibly.  In the recently released  GigaOm Radar for Autonomous Security Operations Center (SOC) , they accurately state that "the SOC will not—and should not—be fully autonomous."  As more vendors attempt to chall...

Cybersecurity researchers have discovered a stealthy backdoor named  Effluence  that's deployed following the successful exploitation of a recently disclosed security flaw in Atlassian Confluence Data Center and Server. "The malware acts as a persistent backdoor and is not remediated by applying patches to Confluence," Aon's Stroz Friedberg Incident Response Services  said  in an analysis published earlier this week. "The backdoor provides capability for lateral movement to other network resources in addition to exfiltration of data from Confluence. Importantly, attackers can access the backdoor remotely without authenticating to Confluence." The attack chain documented by the cybersecurity entity entailed the exploitation of  CVE-2023-22515  (CVSS score: 10.0), a critical bug in Atlassian that could be abused to create unauthorized Confluence administrator accounts and access Confluence servers. Atlassian has since disclosed a second flaw known as...

A group with links to Iran targeted transportation, logistics, and technology sectors in the Middle East, including Israel, in October 2023 amid a surge in Iranian cyber activity since the onset of the Israel-Hamas war. The attacks have been attributed by CrowdStrike to a threat actor it tracks under the name  Imperial Kitten , and which is also known as Crimson Sandstorm (previously Curium), TA456, Tortoiseshell, and Yellow Liderc. The latest findings from the company build on prior reports from  Mandiant ,  ClearSky , and  PwC , the latter of which also detailed instances of strategic web compromises (aka watering hole attacks) leading to the deployment of IMAPLoader on infected systems. "The adversary, active since at least 2017, likely fulfills Iranian strategic intelligence requirements associated with IRGC operations," CrowdStrike  said  in a technical report. "Its activity is characterized by its use of social engineering, particularly job recrui...

Urdu-speaking readers of a regional news website that caters to the Gilgit-Baltistan region have likely emerged as a target of a watering hole attack designed to deliver a previously undocumented Android spyware dubbed  Kamran . The campaign, ESET has  discovered , leverages Hunza News (urdu.hunzanews[.]net), which, when opened on a mobile device, prompts visitors of the Urdu version to install its Android app directly hosted on the website. The app, however, incorporates malicious espionage capabilities, with the attack compromising at least 20 mobile devices to date. It has been available on the website since sometime between January 7, and March 21, 2023, around when  massive protests  were held in the region over land rights, taxation, and extensive power cuts. The malware, activated upon package installation, requests for intrusive permissions, allowing it to harvest sensitive information from the devices.  This includes contacts, call logs, calendar ...

The threat actor known as Lace Tempest has been linked to the exploitation of a zero-day flaw in SysAid IT support software in limited attacks, according to new findings from Microsoft. Lace Tempest, which is known for distributing the Cl0p ransomware, has in the past leveraged zero-day flaws in  MOVEit Transfer  and  PaperCut servers . The issue, tracked as  CVE-2023-47246 , concerns a path traversal flaw that could result in code execution within on-premise installations. It has been patched by SysAid in version 23.3.36 of the software. "After exploiting the vulnerability, Lace Tempest issued commands via the SysAid software to deliver a malware loader for the Gracewire malware," Microsoft  said . "This is typically followed by human-operated activity, including lateral movement, data theft, and ransomware deployment." According to SysAid, the threat actor has been  observed  uploading a WAR archive containing a web shell and other payloads in...

A new  malvertising campaign  has been found to employ fake sites that masquerade as legitimate Windows news portal to propagate a malicious installer for a popular system profiling tool called CPU-Z. "This incident is a part of a larger malvertising campaign that targets other utilities like Notepad++, Citrix, and VNC Viewer as seen in its infrastructure (domain names) and cloaking templates used to avoid detection," Malwarebytes' Jérôme Segura  said . While malvertising campaigns are known to set up replica sites advertising widely-used software, the latest activity marks a deviation in that the website mimics WindowsReport[.]com. The goal is to trick unsuspecting users searching for CPU-Z on search engines like Google by serving malicious ads that, when clicked, redirect them to the fake portal (workspace-app[.]online). At the same time, users who are not the intended victims of the campaign are served an innocuous blog with different articles, a technique known a...

While intended for convenience and efficient communication, email auto-forwarding rules can inadvertently lead to the unauthorized dissemination of sensitive information to external entities, putting confidential data at risk of exposure to unauthorized parties. Wing Security (Wing), a SaaS security company,  announced yesterday  that their SaaS shadow IT discovery methods now include a solution that solves for auto-email forwarding as well. While Wing's shadow IT solution is  offered as a free tool  that can be onboarded and used as a self-service, users willing to upgrade will be able to enjoy the company's new Gmail and Outlook integrations, which broaden the company's discovery capabilities and extend their data security features. The risks of email auto-forwarding rules Auto-forwarding emails is a great way to save time on repetitive tasks and are therefore very popular among employees who regularly collaborate and share information with external business par...
