The prolific North Korean nation-state actor known as the Lazarus Group has been linked to a new remote access trojan called MagicRAT. The previously unknown piece of malware is said to have been deployed in victim networks that had been initially breached via successful exploitation of internet-facing VMware Horizon servers, Cisco Talos said in a report shared with The Hacker News. "While being

By Jung soo An, Asheer Malhotra and Vitor Ventura. Cisco Talos has discovered a new remote access trojan (RAT) we're calling "MagicRAT," developed and operated by the Lazarus APT group, which the U.S. government believes is a North Korean state-sponsored actor. Lazarus deployed MagicRAT after the successful exploitation of vulnerabilities in VMWare Horizon platforms. We've also found links between MagicRAT and another RAT known as "TigerRAT," disclosed and attributed to Lazarus by the Korean Internet & Security Agency (KISA) recently. TigerRAT has evolved over the past year to include new functionalities that we illustrate in this blog. Executive Summary Cisco Talos has discovered a new remote access trojan (RAT), which we are calling "MagicRAT," that we are attributing with moderate to high confidence to the Lazarus threat actor, a state-sponsored APT attributed to North Korea by the U.S. Cyber Security & Infrastructure Agency (CISA). This new RAT was found on victims ...

The India native has transitioned from a reverse-engineer hobbyist to a public speaker in just a few years   By Jon Munshaw.  Ninety percent of Asheer Malhotra’s work will never see the light of day. But it’s that 10 percent that keeps him motivated to keep looking for something new.  The Talos Outreach researcher spends most of his days looking into potential new threats. Many times, that leads to dead ends of threats that have already been discovered and blocked or don’t have any additional threads to pull on.  But eventually, the “lightbulb goes off,” as he puts it, which indicates something is a new threat the wider public needs to know about. During his time at Talos, Malhotra has spent much of his time looking into cyber attacks and state-sponsored threat actors in Asia, like the Transparent Tribe group he’s written about several times.  “At some point, I say ‘Hey, I don’t think I’ve seen this before.’ I start analyzing public disclosures, and slowly start gaining confidence and...

This Metasploit module exploits an authenticated command injection vulnerability affecting Cisco ASA-X with FirePOWER Services. This exploit is executed through the ASA's ASDM web server and lands in the FirePower Services SFR module's Linux virtual machine as the root user. Access to the virtual machine allows the attacker to pivot to the inside network, and access the outside network. Also, the SFR virtual machine is running snort on the traffic flowing through the ASA, so the attacker should have access to this diverted traffic as well. This module requires ASDM credentials in order to traverse the ASDM interface. A similar attack can be performed via Cisco CLI (over SSH), although that isn't implemented here. Finally, it's worth noting that this attack bypasses the affects of the lockdown-sensor command (e.g. the virtual machine's bash shell shouldn't be available but this attack makes it available). Cisco assigned this issue CVE-2022-20828. The issue affects all Cisco ASA that sup...

wolfSSL through 5.0.0 allows an attacker to cause a denial of service and infinite loop in the client component by sending crafted traffic from a Machine-in-the-Middle (MITM) position. The root cause is that the client module accepts TLS messages that normally are only sent to TLS servers.

By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  This week marks about 90 days before my wife’s due date with our first child, a baby girl. We’re both incredibly excited and nervous at the same time, and we have much to discuss, like how to lay out the nursery, what times we’ll put her down for a nap and who must be the one to get up the first time she starts crying at 2 a.m.  But the first true argument my wife and I have had about having a child is whether we should show the baby’s face on Instagram.  This child isn’t even born yet, and social media companies are probably already building out a data profile on her. I signed up for the What to Expect app so I could follow along with my wife’s pregnancy progress and learn more about what she’s going through and how the baby is developing. Already I’m getting targeted ads on the app and my Instagram for specific brands of baby food, the stroller that we’ve listed on our registry and an automati...

So far 2022 confirms that passwords are not dead yet. Neither will they be anytime soon. Even though Microsoft and Apple are championing passwordless authentication methods, most applications and websites will not remove this option for a very long time. Think about it, internal apps that you do not want to integrate with third-party identity providers, government services, legacy applications,

The attack infrastructure used to target Cisco in the May 2022 incident was also employed against an attempted compromise of an unnamed workforce management solutions holding company a month earlier in April 2022. Cybersecurity firm Sentire, which disclosed the findings, raised the possibility that the intrusions could be the work of a criminal actor known as mx1r, who is said to be a member of
