Law enforcement continues to keep up the pressure on ransomware operations with infrastructure hacks and million-dollar rewards, leading to the shut down of criminal operations.
Due to this increased pressure by law enforcement, the BlackMatter (DarkSide) ransomware gang announced to affiliates that they were shutting down this week after members were missing.
BleepingComputer later discovered that BlackMatter began moving existing victims to LockBit ransomware’s infrastructure to continue extortion demands.
To keep pressure on the DarkSide gang and warn that rebranding to a new operation won’t stop law enforcement, the US Department of State announced a $10 million reward for identifying or locating key leaders in the organization. In addition, the US government is also offering $5 million for the arrest of any individuals participating in future attacks using DarkSide variants.
The FBI also issued advisories this week warning that HelloKitty has added DDoS attacks to their arsenal, that ransomware gangs commonly conduct attacks “during time-sensitive financial events,” and that gangs are targeting tribal-owned businesses, including casinos.
Ransomware attacks we saw this week were against the UK Labour Party and the Newfoundland and Labrador health systems.
Contributors and those who provided new ransomware information and stories this week include: @serghei, @malwareforme, @LawrenceAbrams, @BleepinComputer, @fwosar, @DanielGallagher, @Ionut_Ilascu, @struppigel, @jorntvdw, @VK_Intel, @billtoulas, @malwrhunterteam, @FourOctets, @demonslay335, @PolarToffee, @Seifreed, @CofenseLabs, @TalosSecurity, @vxunderground, @pancak3lullz, @Fortinet@GelosSnake, @nakashimae, @DDaltonBennett, @fbgwls245, @pcrisk, and @Amigo_A_.
The Chaos Ransomware gang encrypts gamers’ Windows devices through fake Minecraft alt lists promoted on gaming forums.
The U.S. Federal Bureau of Investigation (FBI) has sent out a flash alert warning private industry partners that the HelloKitty ransomware gang (aka FiveHands) has added distributed denial-of-service (DDoS) attacks to their arsenal of extortion tactics.
The BlackShadow hacking group attacked the Israeli hosting provider Cyberserve to steal client databases and disrupt the company’s services.
The Canadian province of Newfoundland and Labrador has suffered a cyberattack that has led to severe disruption to healthcare providers and hospitals.

PCrisk found new STOP ransomware variants that append the .cool and .palq extensions to encrypted files.
The Federal Bureau of Investigation (FBI) warns that ransomware gangs are targeting companies involved in “time-sensitive financial events” such as corporate mergers and acquisitions to make it easier to extort their victims.
The BlackMatter ransomware is allegedly shutting down its operation due to pressure from the authorities and recent law enforcement operations.
The U.K. Labour Party notified members that some of their information was impacted in a data breach after a ransomware attack hit a supplier managing the party’s data.
With the BlackMatter ransomware operation shutting down, existing affiliates are moving their victims to the competing LockBit ransomware site for continued extortion.
A major overseas ransomware group shut down last month after a pair of operations by U.S. Cyber Command and a foreign government targeting the criminals’ servers left its leaders too frightened of identification and arrest to stay in business, according to several U.S. officials familiar with the matter.
Amigo-A found a new Polaris ransomware that is targeting Linux and dropping ransom notes named WARNING.txt.
