New ransomware posing as COVID‑19 tracing app targets Canada; ESET offers decryptor
New ransomware CryCryptor has been targeting Android users in Canada, distributed via two websites under the guise of an official COVID-19 tracing app provided by Health Canada. ESET researchers analyzed the ransomware and created a decryption tool for the victims.
CryCryptor surfaced just a few days after the Canadian government officially announced its intention to back the development of a nation-wide, voluntary tracing app called COVID Alert. The official app is due to be rolled out for testing in the province of Ontario as soon as next month.
ESET informed the Canadian Centre for Cyber Security about this threat as soon as it was identified.
Once the user falls victim to CryCryptor, the ransomware encrypts the files on the device – all the most common types of files – but instead of locking the device, it leaves a "readme" file with the attacker's email in every directory with encrypted files.
Fortunately, we were able to create a decryption tool for those who fall victim to this ransomware.
After we spotted the tweet that brought this ransomware to our radar (the researcher who discovered it mistakenly labeled the malware as a banking trojan), we analyzed the app. We discovered a bug of the type "Improper Export of Android Components" that MITRE labels as CWE-926.
Due to this bug, any app that is installed on the affected device can launch any exported service provided by the ransomware. This allowed us to create the decryption tool – an app that launches the decrypting functionality built into the ransomware app by its creators.

Electronic malware and biological malware, together, they will cull the human gene pool.
*"Human" here is used loosely.

What need to get culled from the human gene pool is the little shitfuck behind these ransomware attacks seriously. They are pure evil, they have no shame, they attack anything and anyone, including hospitals, putting real lives in danger.
They need to be hunted down and killed.

Death is too good for them. They must suffer as their victims suffered. They must see their world, all they hold dear, ripped from them as it was ripped from those they victimized.

Or you could do proper offline backups.
