Malaysian law enforcement authorities have  announced  the takedown of a phishing-as-a-service (PhaaS) operation called  BulletProofLink . The Royal Malaysia Police said the effort, which was carried out with assistance from the Australian Federal Police (AFP) and the U.S. Federal Bureau of Investigation (FBI) on November 6, 2023, was based on information that the threat actors behind the platform were based out of the country. To that end, eight individuals aged between 29 and 56, including the syndicate's mastermind, have been arrested across different locations in Sabah, Selangor, Perak, and Kuala Lumpur, New Straits Times  reported . Along with the arrests, authorities confiscated servers, computers, jewelry, vehicles, and cryptocurrency wallets containing approximately $213,000. BulletProofLink , also called BulletProftLink, is known for offering ready-to-use phishing templates on a subscription basis to other actors for conducting credential harvesting ca...

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...

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...
