Russians considering spacewalk as part of airleak investigation
The Russians are now considering having their astronauts on ISS do a spacewalk to inspect the outside of the Soyuz capsule for evidence of sealant work at the location of the drill hole that caused the airleak.
If the spacewalk is attempted, the cosmonauts would have to get to the Habitation Module, peel off soft thermal layers blanketing the spacecraft and then cut through the meteoroid shielding bordering this section of the spacecraft at a distance of around 1.5 centimeters from its pressurized hull.
To access the area of the hole on the exterior of the Soyuz, Russian officials are developing a spacewalk scenario relying on the available Strela boom, GStM. The telescopic device can be used to carry a cosmonaut secured to a special anchor at the end of the boom to a location aboard the station otherwise inaccessible to spacewalkers due to lack of railings.
The spacewalk would take place sometime in November or December. The goal is to help confirm that the sealant work was done on the ground, as well as help pinpoint when.

To paraphrase Mark Watney from The Martian, it looks like the Russian are going to CSI the crap out of that drill hole.
