Ransomware gang donates stolen money to charities

The Darkside hacker group has donated $ 20,000 of extorted money to charities. They released receipts for two donations of 0.88 BTC (about $ 10,000) to The Water Project and Children International. However, when a donation comes from criminal proceeds, the law requires to reject it. Both charities have said that they will not accept BTC donations, although they have no way to return them. Darkside used a cryptocurrency mixing service, which makes the donations untraceable. Darkside appeared in August 2019; the group uses typical ransomware schemes. They claim only to attack large profitable companies and not hospitals, schools, or governments.

hexway commentary:

Are they the new Robin Hoods? No.

Are they criminals who create and distribute ransomware? Yes.

Will The Water Project and Children International cancel the payment? Obviously, yes.

The only way for hacker gangs to be useful is to surrender, serve time, get out of jail, get the GED, and start making money with a printer cartridge company.

GravityRAT Windows malware now attacks Android and macOS

GravityRAT, a Trojan known for attacking Windows systems, can now infect Android and macOS devices. Supposedly developed by a Pakistani cybercriminal group, it has existed since at least 2015 and is used in targeted attacks against India's military organizations. Researchers found an updated RAT sample in Android spyware. In total, more than 10 versions of the malware were detected; they are disguised as legitimate file sharing apps or media players. They can exfiltrate data and communicate with the nortonupdates [.] C&C server, which is also used by other malware (Enigma and Titanium). Malicious apps download the GravityRAT payload from the C&C server and add a scheduled task to the infected device to preserve persistence.
