He didn’t intend to:
So it would not be surprising if the atheistic Soviet regime of the 1980s would see it as a legitimate target to discredit the Shroud, and through that Christianity, by one its agents hacking into each of the three radiocarbon dating laboratories’ computers, and replacing the actual radiocarbon dates of the Shroud that the laboratories’ accelerated mass spectrometers were determining, with bogus dates which when calibrated would cluster around 1325 +/- 65 years.
I have presented this proposal as a question, "Were the radiocarbon laboratories duped by a computer hacker?" because in the nature of the case, barring a belated confession, my proposal is unlikely ever to be confirmed as correct, even if it is correct. The hacker would be unlikely to admit it because he would be prosecuted and gaoled for breaking into government computers, as Hess was. And the laboratories would be unlikely to admit they had been duped by a hacker, even if they realised they had been. Whatever evidence there was in the laboratories’ computers, the hacker would almost certainly have deleted it, and even if he didn’t, it is most unlikely that it would still exist in the laboratories’ 1988 computers.
Anyway, in the final analysis it is the Shroud anti-authenticists’ problem to find a explanation for what went wrong with their carbon dating of the first-century Shroud to the 13th-14th centuries. As Thomas de Wesselow pointed out, we Shroud pro-authenticists don’t need to find an explanation of what went wrong with the 1988 radiocarbon date of the Shroud. We can just dismiss it out of hand as a "’rogue’ radiocarbon date" as archaeologists routinely do when a radiocarbon date is contradicted by the majority of the other evidence:
