Tactics of Supply-Chain Attack Group Exposed
Recent research by ESET has uncovered some of the tactics and tools used by the Winnti hacking group that has been carrying out supply-chain attacks against gaming companies since at least 2011.

That campaign was estimated to have impacted tens of thousands or perhaps hundreds of thousands of users.
ESET researchers have since discovered that the hackers use a backdoor called PortReuse.

The compromise was disclosed to the targeted firm. The researchers also found a botnet used by Winnti to mine for cryptocurrency.
