New Group Emerges with Similarities to ALPHV/BlackCat
Threat Actors
Arete Analysis

A new Ransomware-as-a-Service (RaaS) group calling themselves Cicada3301 emerged in early June 2024 and has been using recruitment posts in dark web forums to attract new affiliates. As with many of the current active RaaS organizations, Cicada3301 uses double extortion, encrypting victim systems and stealing sensitive data. They have a data leak site (DLS) on the dark web where they have been posting victims since mid-June. The group has been observed encrypting Linux/VMware ESXi in addition to Windows operating systems.
Similarities with ALPHV/BlackCat
A recent analysis of Cicada3301’s ransomware conducted by cyber researchers discovered several significant code overlaps with the ransomware used by ALPHV, the prolific threat group who was targeted by law enforcement earlier this year and subsequently shut down their RaaS. According to researchers from Truesec, Cicada3301 and ALPHV ransomware similarities include:
Written in Rust programming language
Use the ChaCha20 algorithm for encryption
Use almost identical commands to shutdown VM and remove snapshots
Use the same command parameters to provide a graphic output on encryption
Use intermittent encryptions on files larger than 100MB
Use a similar naming convention for the ransom note file and the same key parameter used to decrypt the ransomware note
In addition to the code overlaps, Arete has also observed similarities in the format and design of the Tor chats Cicada3301 uses to communicate ransom payments to its victims. Like the Tor chats ALPHV used, Cicada3301’s has a similar layout, with certain words bolded in the instructions, a countdown timer, two prices listed based on whether the victim pays within the time limit posted, and payments are accepted in both Bitcoin and Monero.

Will the Real Cicada Please Stand Up?
This new ransomware group also appears to have taken their name from Cicada 3301, which was an unknown group who posted elaborate puzzles on the internet between 2012 and 2014. Solving the puzzles required knowledge of computer science and data security concepts such as coding, cryptography, and encryption. The last puzzle posted by the group was in early 2014 and has still not been solved. Although the purpose of the puzzles, and individuals who created them remains a mystery, there is no indication that this current ransomware group has any association with the original Cicada 3301. This wouldn’t be the first time a threat actor has used the name, as an unrelated group of hackers operating in 2015 also called themselves 3301.
Analyst Comments
At this time, it is too early to assess whether the similarities between the two groups are coincidental, or if there is a connection in the form of a rebranding of ALPHV, a new group working with former developers from ALPHV, or if ALPHV’s ransomware code was sold after the RaaS shut down its operations earlier this year. Following ALPHV’s exit scam and departure from the ransomware landscape, it was assumed members of the RaaS would rebrand or re-affiliate with other threat groups, so any of these connections are plausible. However, with 24 victims already posted to its DLS in less than three months, Cicada3301 already appears to be an emerging threat in the near-term, regardless of who is ultimately behind the new RaaS.

Europol Disrupts AudiA6 Crypto Laundering Service
European authorities have dismantled AudiA6, a major cryptocurrency laundering service linked to ransomware groups and broader cybercriminal networks. Between 2022 and 2025, the platform is believed to have processed over €336 million in illicit funds, enabling threat actors to obscure financial trails and monetize cybercrime proceeds. Its operators are also suspected of running Dark2Web, a dark web forum that facilitated collaboration, services, and connections among cybercriminals globally. This development underscores the expanding role of sophisticated, large-scale cryptocurrency laundering services in sustaining the cybercrime economy, enabling threat actors to obscure illicit funds and evade regulatory controls.
What’s Notable and Unique
Following law enforcement disruption of Cryptex and Garantex, AudiA6 emerged as another platform involved in financial activities linked to ransomware groups. Investigators believe that AudiA6 became a central hub for cybercriminals seeking to launder stolen digital assets while obscuring the transaction trail from authorities.
On June 10, 2026, a coordinated operation resulted in two arrests in Georgia, the dismantling of key infrastructure (30+ servers, 25 domains), the freezing or seizure of over €778,000 in crypto, and the takedown of the AudiA6 and Dark2Web platforms.
Analyst Comments
Ransomware groups and cybercriminal networks are increasingly leveraging sophisticated techniques, including chain-hopping, decentralized exchanges, and mixer-as-a-service platforms, to rapidly move illicit cryptocurrency across multiple blockchains, effectively obscuring transaction trails. Concurrently, the widespread use of fraudulent exchange accounts, mule wallets, and privacy-enhancing tools has elevated cryptocurrency laundering to a core enabler of the cybercrime ecosystem, allowing actors to bypass anti-money-laundering controls at scale. This investigation identified over 6,000 KYC records linked to money-mule accounts, many of which were tied to Russian-speaking intermediaries specifically recruited to facilitate the movement of illicit proceeds. These threat actors systematically used both commercial and domain-controlled email services to establish mule accounts across multiple cryptocurrency platforms. Collectively, these findings underscore the growing scale, coordination, and professionalization of cryptocurrency-enabled crime, highlighting the critical need for sustained, intelligence-led, and internationally coordinated efforts to disrupt these evolving financial ecosystems.

Threat Actors Leverage AI for EDR Evasion
A threat actor has developed and deployed a ransomware attack toolkit enhanced with AI-assisted development workflows, enabling automated Active Directory (AD) discovery and improved EDR evasion capabilities. The toolkit leverages agent-based AI systems, such as Claude’s Opus and Cursor agents, for iterative malware development, testing, and refinement.
What’s Notable and Unique
Researchers have highlighted that this toolkit can not only generate ransomware code but also bypass sophisticated security defenses and identify AD networks for malware distribution.
The framework incorporates multiple capabilities, including automated AD discovery and reconnaissance mechanisms, iterative EDR testing environments to refine evasion techniques, and a command-and-control (C2) infrastructure that leverages Telegram APIs and Cloudflare redirectors for stealth.
Additionally, some agents were tasked with checking security research and technical posts for various bypass techniques. The agents recognized what was required for reproduction, extracted the techniques, mapped them to the MITRE ATT&CK knowledge base of adversary behaviors, set up a test lab, carried out the methodology, and reported the results.
After a few repetitions, the modules seemed to avoid nearly all EDR solutions, despite the agent’s initial suggestion of a high failure rate. Although researchers found no evidence that AI was embedded in deployed malware or was operating independently in victim environments, the technology was still used to accelerate the iterative process of developing, testing, and refining payloads against security products, shortening the period between the publication of offensive security research and its practical implementation by threat actors.
Analyst Comments
AI-driven tools like this could accelerate the pace and sophistication of ransomware attacks, enabling even relatively inexperienced actors to launch high-impact campaigns. This development underscores the urgent need for security solutions to adapt to AI-assisted threats. Organizations must respond by strengthening detection engineering, improving visibility across environments, and maintaining robust security fundamentals.

CMS Vulnerability Leads to ClickFix Campaign
Threat actors compromised at least 700 education and technology websites in a recent ClickFix campaign by exploiting a critical SQL injection flaw (CVE-2026-26980) in the Ghost content management system (CMS). Adversaries combined the vulnerability with the ClickFix social engineering tactic to steal admin keys and inject a malicious JavaScript that delivers a fake Cloudflare or CAPTCHA verification pop-up, tricking victims into copying and pasting a malicious command into their systems.
What’s Notable and Unique
Rather than targeting the end user first, this campaign is unique in its initial exploitation of the system, followed by social engineering attempts. This hybrid attack style is likely being leveraged to bypass traditional defenses.
This recent campaign also highlights how trusted web properties can be weaponized at scale and coupled with unpatched CMS vulnerabilities. Rather than using the CMS compromise to perpetrate a single attack, threat actors turned it into a supply-chain attack that ultimately affected over 700 trusted websites.
Analyst Comments
As network defenders and their tools enhance threat detection capabilities, adversaries increasingly seek methods to bypass these defenses. By combining vulnerability exploitation, social engineering techniques, and staging for ancillary attacks, this campaign successfully bypassed traditional defenses and inflicted significant impact. Defending against hybrid cyberattacks requires comprehensive security controls beyond simply patching vulnerabilities. Organizations should focus on limiting movement within the environment, detecting abuse of trusted applications, and preventing end-user manipulation.
