US officials have seized server infrastructure linked to a data extortion group known as Dispossessor and RADAR.
Officials from the DOJ and FBI have seized nine domains and 24 servers linked to the gang's operations.
A criminal complaint was also filed against an individual going by the hacker pseudonym of "Brain," which officials believe is based out of Europe—possibly Poland.
The Dispossessor group is a rather unique operation that is the result of the recent turmoil in the ransomware ecosystem over the past two years.
The group formed around August 2023 and is a team-up between two "affiliate groups/individuals" who used to work for larger ransomware gangs.
These "affiliates" worked by hacking into corporate or government networks, stealing files, and then deploying a file-encryptor (aka ransomware) on the victim's network.
This ransomware strain was usually rented from a Ransomware-as-a-Service (RaaS) platform, with the affiliate getting a percentage of what a victim paid to the RaaS platform for the decryption key or to avoid having their stole files published online.
According to reports from DataBreaches.net, SentinelOne, SOCRadar, and vxdb, the Dispossessor group appears to have formed when two former affiliates named RADAR and Dispossessor decided to team up.
This team-up operated at first as an initial access broker on underground forums such as BreachForums, although according to reports they didn't seem to be that good at it, often asking for help on intrusions and being ridiculed for it.
The group evolved and launched its own data leak site in February 2024.
At first, they listed old victims from their past attacks. Based on entries on the site, it appears that RADAR and Dispossessor worked for groups such as LockBit, Clop, Hunters International, 8Base, and Snatch.
Newer entries eventually began being added to the site throughout the year, such as the Delhi Hospital in Louisiana and Aire Dental in New York.
Based on public reporting, the group was still engaging in data extortion attacks only. This appears to have changed somewhere in May-June, when the Dispossessor gang announced they were launching a full-blown RaaS of their own, with the ability to create custom ransomware builds for their attacks.
Both the leak site and the RaaS appear to have been built on the leaked source code of the LockBit ransomware gang—with the data leak site being basically a green-themed redesign of the old LockBit leak site.
This was no surprise, as per reports, the Dispossessor seems to have been one of the biggest LockBit affiliates, having tallied up more than 330 victims while working for the LockBit group in previous years.
As the linked Mastodon post from above seems to suggest, the gang appears to have misconfigured their infrastructure, leaking some of their real-world IP addresses.
The group genuinely appears to have limited technical skills, asking many times on hacking forums for IT-related help, which is not the ideal scenario when you're trying to hide from the feds after you've extorted companies for millions of US dollars.
An OPSEC mistake was very likely what led to the group's downfall, and an arrest won't surprise us at all—if, indeed, mister big-"Brain" RaaS operator is based out of Europe.
Breaches, hacks, and security incidents
Crown Equipment hack: Forklift maker Crown disclosed a security breach last week after a threat actor gained access to one of its IT environments. The breach took place at the start of June, and Crown says the attacker was able to gain access to some employee benefits and retirement data. Crown says it since contained the intrusion. The company's name has not been listed on any ransomware leak site.
Evolution Mining ransomware attack: Australian gold mining company Evolution Mining says it was the victim of a ransomware attack last week. The company says it handled the incident with no material impact on its operations. The incident comes two months after the BianLian ransomware group hit Northern Minerals, another Australian mining company. Evolution Mining is one of Australia's six biggest mining corporations.

Hacker leaks Netflix shows: A hacker leaked last week several upcoming episodes from major Netflix and Crunchyroll shows. Netflix confirmed and blamed the leaks on one of its post-production companies. Sources claim the source of the leak is Iyuno, a California company specializing in subtitling and content distribution services. Iyuno disclosed a security breach last Friday but did not take the blame for the Netflix show leaks. According to Beebom, the leaks included episodes from the upcoming season two of Emmy award-winning series Arcane.
POLADA leak: Hackers have stolen and leaked more than 50,000 sensitive files from Poland's anti-doping agency POLADA. The incident occurred last week and exposed personal details and medical records of thousands of Polish athletes. The agency claims the hack was carried out by "the services of an enemy state." A Polish minister told local media the government is currently looking at Russia or Belarus as the potential source of the leak. [Additional coverage in Notes from Poland and ZaufanaTrzeciaStrona]
C-Edge hack: Juniper Networks has published a report on how a threat actor exploited a Jenkins vulnerability to breach Indian software provider C-Edge Technologies and deployed ransomware in an incident that impacted a large part of the Indian banking sector this month.
mSpy data takedown: Ukrainian company Brainstack has filed a legal takedown against FlokiNet, the web hosting provider of DDoSecrets. The company has asked the web host to remove data belonging to a spyware company named mSpy.

Google AdSense leaves Russia: Google is currently notifying Russian users that it will deactivate all AdSense accounts by the end of the month. Russian users will not be able to monetize websites and YouTube videos through AdSense ads. After Russia's invasion of Ukraine, Google disabled the ability for Russians to monetize Russian traffic, but they could still receive payments for traffic coming from abroad. The company plans to make final payments to Russian users between August 21 and 26 and then leave the Russian market altogether. Some Russian bloggers and YouTubers say the AdSense ban can be avoided by changing an account's country of origin and using a foreign card number to receive payments. The move comes after the Russian government blocked access to YouTube earlier this month and after a new round of US sanctions. [Additional coverage in The Moscow Times]
Government, politics, and policy
US presidential campaign hacks: The FBI said Monday that it is investigating attempts to hack both the Trump and Biden-Harris campaigns. The FBI says the investigation includes attempts to hack three Biden-Harris campaign staffers and former Trump advisor Roger Stone. The agency has confirmed the investigation after the Trump campaign said it was hacked by Iran earlier this year. Alleged Iranian hackers leaked documents from the Trump campaign to Politico at the end of July. The same files were also shared with the New York Times and Washington Post, which chose not to cover the files and the breach for days until Politico broke the news. The way the two outlets handled the hack is a 180-turn to how they treated the Clinton campaign's hacked emails in 2016 when they went with a fine tooth comb over the leaked data for months.
NIST PQE standards are out: The US National Institute of Standards and Technology (NIST) announced three new encryption algorithms designed to protect against attacks with quantum computers. NIST has been working on the standards for the past eight years. The three were selected from 82 algorithms submitted from 25 countries. The three selected standards are ML-KEM (short for Module-Lattice-Based Key-Encapsulation Mechanism, or FIPS 203), ML-DSA (short for Module-Lattice-Based Digital Signature Algorithm, or FIPS 204), and SLH-DSA (short for Stateless Hash-Based Digital Signature Algorithm, or FIPS 205). A fourth algorithm named FN-DSA (short for Fast-Fourier Transform over NTRU-Lattice-Based Digital Signature Algorithm, or FIPS 206) is still under development.

Cybercrime and threat intel
Angler EK and Ransom Cartel admin charged: The US government has charged a Belarussian and Ukrainian dual-national for his role in two long-running cybercrime operations. Officials say Maksim Silnikau was a core member of the Angler exploit kit malvertising operation for nine years between 2013 and 2022. He also founded and ran the Ransom Cartel ransomware service in May 2021. UK officials say that while part of the Angler gang, Silnikau was also involved back in 2011 in the deployment of Reveton, the first-ever widely distributed ransomware strain. The UK NCA says that at its peak, Angler accounted for 40% of all exploit kit infections and was making its operators around $34 million per year. The 38-year-old Silnikau was arrested in a resort town in southern Spain in July of last year and extradited to the US last week to face charges for his crimes. The US has also charged two other individuals for their role in the Angler malvertising operation—Vladimir Kadariya, 38, from Belarus, and Andrei Tarasov, 33, from Russia.
CryptoCore group: A cybercrime group named CryptoCore has stolen over $5.4 million worth of crypto assets using a highly sophisticated social media scam campaign. The group used hacked accounts with large followings, a flood of online comments, and deep-fake videos to redirect users to scam sites impersonating famous brands. Victims were asked to invest in crypto-tokens supposedly managed by the large brands but had their funds stolen from their accounts. Security firm Avast described the group as very professional, having deep fake videos prepared for multiple topics in advance, ready to be weaponized at the most opportune time. Recent CryptoCore campaigns exploited Donald Trump presidential nomination, several SpaceX flights, and even Apple's yearly developer conference.
