DarkGate | Breaking Cybersecurity News | The Hacker News

A new social engineering campaign has leveraged Microsoft Teams as a way to facilitate the deployment of a known malware called DarkGate . "An attacker used social engineering via a Microsoft Teams call to impersonate a user's client and gain remote access to their system," Trend Micro researchers Catherine Loveria, Jovit Samaniego, and Gabriel Nicoleta said . "The attacker failed to install a Microsoft Remote Support application but successfully instructed the victim to download AnyDesk, a tool commonly used for remote access." As recently documented by cybersecurity firm Rapid7, the attack involved bombarding a target's email inbox with "thousands of emails," after which the threat actors approached them via Microsoft Teams by masquerading as an employee of an external supplier. The attacker then went on to instruct the victim to install AnyDesk on their system, with the remote access subsequently abused to deliver multiple payloads, includ...

The threat actors linked to the Black Basta ransomware have been observed switching up their social engineering tactics , distributing a different set of payloads such as Zbot and DarkGate since early October 2024. "Users within the target environment will be email bombed by the threat actor, which is often achieved by signing up the user's email to numerous mailing lists simultaneously," Rapid7 said . "After the email bomb, the threat actor will reach out to the impacted users." As observed back in August, the attackers make initial contact with prospective targets on Microsoft Teams, pretending to be support personnel or IT staff of the organization. In some instances, they have also been observed impersonating IT staff members within the targeted organization. Users who end up interacting with the threat actors are urged to install legitimate remote access software such as AnyDesk, ScreenConnect, TeamViewer, and Microsoft's Quick Assist. The Window...

In cybersecurity, confidence is a double-edged sword. Organizations often operate under a false sense of security , believing that patched vulnerabilities, up-to-date tools, polished dashboards, and glowing risk scores guarantee safety. The reality is a bit of a different story. In the real world, checking the right boxes doesn't equal being secure. As Sun Tzu warned, "Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat." Two and a half millennia later, the concept still holds: your organization's cybersecurity defenses must be strategically validated under real-world conditions to ensure your business's very survival. Today, more than ever, you need Adversarial Exposure Validation (AEV) , the essential strategy that's still missing from most security frameworks. The Danger of False Confidence Conventional wisdom suggests that if you've patched known bugs, deployed a stack of well-regarded security tools, and passed the nec...

Cybersecurity researchers have observed a spike in email phishing campaigns starting early March 2024 that delivers  Latrodectus , a nascent malware loader believed to be the successor to the IcedID malware. "These campaigns typically involve a recognizable infection chain involving oversized JavaScript files that utilize WMI's ability to invoke msiexec.exe and install a remotely-hosted MSI file, remotely hosted on a WEBDAV share," Elastic Security Labs researchers Daniel Stepanic and Samir Bousseaden  said . Latrodectus comes with standard capabilities that are typically expected of malware designed to deploy additional payloads such as QakBot, DarkGate, and  PikaBot , allowing threat actors to conduct various post-exploitation activities. An analysis of the latest Latrodectus artifacts has revealed an extensive focus on enumeration and execution as well as the incorporation of a self-delete technique to delete running files. The malware, besides masquerading as lib...

Phishing campaigns delivering malware families such as DarkGate and PikaBot are following the same tactics previously used in attacks leveraging the now-defunct QakBot trojan. "These include hijacked email threads as the initial infection, URLs with unique patterns that limit user access, and an infection chain nearly identical to what we have seen with QakBot delivery," Cofense  said  in a report shared with The Hacker News. "The malware families used also follow suit to what we would expect QakBot affiliates to use." QakBot, also called QBot and Pinkslipbot, was  shut down  as part of a coordinated law enforcement effort codenamed Operation Duck Hunt earlier this August. The use of DarkGate and PikaBot in these campaigns is not surprising as they can both act as conduits to deliver additional payloads to compromised hosts, making them both an attractive option for cybercriminals. PikaBot's parallels to QakBot were  previously highlighted  by Zscale...
