The weak decays of doubly heavy $\Xi_{QQ}$ baryon induced by flavor changing$b \to d$ and $ c \to u$ flavor changing neutral current within the light conesum rules are studied. Using the parallel components of the light conedistribution amplitudes for $\Lambda_Q$ baryon, the sum rules are constructedand analyzed for the corresponding transition form factors. Having the resultsfor the form factors, the corresponding branching ratios for $\Xi_{QQ} \to\Lambda_Q l^+ l^-$ decays are estimated. While the branching ratio due to $b\to d$ transition is around $10^{-9}$, in $c \to u$ transition case, it isfound as around $10^{-13}$. Hence, $\Xi_{bb} \to \Lambda_b l^+ l^-$ decay hasthe potential of being discovered at LHCb. However, $\Xi_{bb} \to \Lambda_b l^+l^-$ is difficult to be measured due to the extremely small values of obtainedbranching ratio. Our results on the branching ratio are also compared with theresults of the light-front approach.
