Though researchers were not able to identify the malware variant being used in the campaign, they believe with high likelihood that it will include “common legitimate remote administration tools (RATs) for initial access, off-the-shelf penetration testing tools for lateral movement, and the deployment of ransomware or data extortion,” they wrote. The email instructs the recipient to call a number provided so this can be done, which is when the malicious activity occurs.

The message claims that the victim’s IT department already has been notified but that their participation is required to perform an audit on their individual workstation, according to CrowdStrike. Specifically, the email informs the target that it’s coming from their company’s “outsourced data security services vendor,” and that “abnormal activity” has been detected on the “segment of the network which your workstation is a part of.” In their blog post, they included a screenshot of the email sent to recipients impersonating CrowdStrike, which appears legitimate by using the company’s logo. Researchers did not specify what other security companies were being impersonated in the campaign, which they identified on July 8, they said.

However, that website instead led them to a malicious download.ĬrowdStrike also identified a campaign in March of this year in which threat actors used a callback phishing campaign to install AteraRMM followed by Cobalt Strike to assist with lateral movement and deploy additional malware, CrowdStrike researchers said. If people made the call, a friendly person on the other side would give them a website address where the soon-to-be victim could supposedly unsubscribe from the service. That campaign used a similar tactic to try to spur people to make a phone call to opt-out of renewing an online service the recipient purportedly is currently using, Sophos researchers explained at the time. Researchers likened the campaign to one discovered last year dubbed BazarCall by the Wizard Spider threat group.

“Historically, callback campaign operators attempt to persuade victims to install commercial RAT software to gain an initial foothold on the network,” researchers wrote in the post. If a person targeted calls the number, they reach someone who directs them to a website with malicious intent, they said. The campaign employs a typical phishing email aiming to fool a victim into replying with urgency-in this case, implying that the recipient’s company has been breached and insisting that they call a phone number included in the message, researchers wrote. Researchers at CrowdStrike Intelligence discovered the campaign because CrowdStrike is actually one of the companies, among other security firms, being impersonated, they said in a recent blog post.

A new callback phishing campaign is impersonating prominent security companies to try to trick potential victims into making a phone call that will instruct them to download malware.
