Previously undocumented C++ backdoor
FFS - it is just an old fashioned Trojan Horse exe that they con people into downloading via email, with a double file extension like fred.doc.exe - so why name-check C++? To point out how behind the times these people are and get them to use Rust instead?
There is a good bit of description in that report about the sequence the Trojan initiates, mingled with the usual jargon, but come on: that wording isn't trying to imply that there is some kind of secret backdoor inside the very depths of C++ that we never knew about?
It was just there to fool poor, innocent, gullible people, like sensitive young Register reporters, into copying the sensationalist phrase and hiding the fact that this is just a Trojan, with a pointlessly fancy name, and that the only take-away message is should be "take care not to run exes in unsolicited email attachments"!
