The Week in Ransomware – July 23, 2021

There’s plenty of news this week ranging from the US formally accusing China of the recent ProxyLogon vulnerability and Kaseya mysteriously obtaining the universal decryption key.

This week, the US government officially attributed the ProxyLogon Microsoft Exchange attacks to China. Threat actors used this vulnerability to install a variety of malware, including the BlackKingdom ransomware.

In a surprise announcement, Kaseya has stated that they received the universal decryption key for their REvil ransomware attack on July 2. This key will allow all victims of the attack to recover their files for free.

It is unclear how they received this key yesterday as REvil disappeared about two weeks ago. The key is believed to have been obtained by the Russian government, who shared it with the United States.

Other news this week includes an attack on Ecaudor’s CNT, the CNA attack was caused by a fake browser update, and that HelloKitty is using a SonicWall vulnerability to breach networks.

Contributors and those who provided new information and stories about ransomware this week include: @Ionut_Ilascu, @DanielGallagher, @ demons335, @fwosar, @malwareforme, @malwrhunteeteam, @Sleepingcomputer, @PolarToffee, @Seifreed, @VK_Intel, @serghei, @jorntvdw, @struppigel, @LawrenceAbrams, @FourOctets, @LitMoose, @HeinrichsH, @CrowdStrike, @pcrisk, @ QVM36O, @campuscodi, @ chum1ng0, @JakubKroustek, Y @ fbgwls245.
