Several cyberespionage campaigns with a myriad of malicious intentions were reported in the last 24 hours. The Turla APT group is back with a new backdoor dubbed TinyTurla to gain persistence on targeted systems across Germany, the U.S., and Afghanistan. A fileless attack campaign named Water Basilisk used a new variant of HCrypt crypter to distribute numerous RATs to victims’ systems, whereas the z0Miner trojan exploited a flaw in Atlassian Confluence Server to execute its payload.

The BlackMatter ransomware gang also ramped up its attacks by hitting two more organizations over the weekend. The victims are Marketron and New Cooperative. The attackers have demanded $5.9 million in ransom from New Cooperative.
