A vast Russian influence operation on TikTok involving 12,800 fake accounts spreading disinformation about the war in Ukraine to millions of users in Germany, France, Italy, Poland, Israel and Ukraine, has been uncovered by BBC Verify and @DFRLab.
Back in the summer, this video, featuing an AI-generated voice, racked up millions of views on TikTok and later on Twitter.
It falsely accused Ukraine's former defence minister Oleksiy Reznikov and his daughter Anastasiya Shteinhauz of buying a a €7m villa in Cannes, France.
We debunked the viral video back in July. The villa seen in the video wasn't bought by Reznikov, and was actually up for sale.
So, @O_Rob1nson, @adkrobinson and I tried to find out more about the account that originally posted that video to TikTok.
The TikTok account was called "Vladyslav Yashchenko 1".
A few things about the account caught our attention: It had only posted that one video with 1.7m views, its profile picture was a stock image of a random guy, it had several other back up accounts with the same name.
Using hashtag searches, we found similar TikTok accounts.
Here's "Andrea Miller 421" with a profile photo of Chris Evans and only one video featuring an AI-generated voice and a series of still images, falsely accusing Reznikov and Shteinhauz of buying a villa in Madrid.
We soon found similar accounts in multiple languages: Ukrainian, German, French, Russian and Polish.
Nearly all of them had posted one video pushing anti-Ukrainian and pro-Kremlin narratives with Al-generated voice and a stolen profile picture. Some videos had millions of views.
The operation was careful in covering its traces, and never posted the same video from two different accounts. But mistakes were made.
We, for instance, found multiple accounts with the same stolen profile photo but different names.
We found over 800 fake TikTok accounts that seemed to be part of the same operation in five languages, with over 80 million views in total.
The videos targeted dozens of senior Ukrainian officials, portraying them as obsessed with money and uncaring about Ukrainians or the war.
There were linguistic mistakes in some videos typical of Russian speakers, including some Russian phrases that are not used in other languages.
A website previously exposed by Meta as part of a Russian-linked network also appeared in some of the videos we found.
We presented the accounts we'd found to TikTok, whose internal investigation found fake videos in two more languages - Italian and English.
TikTok confirmed this was a sophisticated, covert operation based in Russia, and removed 12,820 accounts.
This is likely the largest influence operation ever uncovered on TikTok.
Its videos, pushing disinformation about Ukraine, have been viewed tens of millions of times in multiple languages, and reposted on other major platforms.
The meme shared by Elon Musk about the pizzagate conspiracy theory is itself based on the completely false claim that James Gordon Meek, a journalist who recently pleaded guilty to possessing child pornography, had debunked pizzagate. Meek never reported on pizzagate.
The completely false claim that James Gordon Meek had debunked pizzagate was spread back in the summer by QAnon followers, like this blue tick account.
The New York Post has never published such a story about Meek. It's a totally fake image and a made up headline.
Elon Musk has once again fallen for a completely false claim, this time based on a fabricated New York Post headline pushed months ago by conspiracy theorists on his own platform.
If he'd done a simple check before tweeting, he'd have found out the whole thing was false.
This video, viewed over 3 million times, claims to show an Israeli settler run over protesters.
The video's from 9 September, during a protest in Tel Aviv against the government's judicial reforms, and involves no settlers.
This video claims to show two "terrorist" Palestinian journalists reporting near a rocket launcher.
The two are in fact Syrian journalists and the video is from 7 October. They reported retaliatory strikes against the Syrian government, after it killed 65 civilians in Idlib.
While Gaza's Al-Shifa hospital has been described by the WHO as a "death zone", the claim that all the premature babies there have died is inaccurate.
Two premature babies tragically died over the weekend, while 31 have now been transferred to an Emirati hospital in Rafah.
Hannah Abutbul, an Israeli influencer, is being falsely doxxed as the woman in the misleading video of a supposed nurse at Al-Shifa hospital speaking out against Hamas.
I spoke to Hannah earlier. She's not the woman in the video.
This digitally altered video, viewed 13 million times, falsely claims to show an advertising in New York in which "support Ukraine" is replaced by "support Israel".
No such ad exists. The real ad right now is about the upcoming Trolls film, via @macrinawang @RitornellaNYC.
WARNING: GRAPHIC
This image, viewed 370,000 times, falsely claims to show a Palestinian child shot dead by Israeli troops while fetching water.
This tragic incident happened in Yemen in 2020, and the child was allegedly shot by a Houthi sniper. She reportedly survived.
A digitally altered image of Israeli actress Gal Gadot holding a sign against Zionism has been viewed a million times.
The original image shows her holding a "we remember" sign for Holocaust Remembrance Day in 2018.
This video, viewed over 7 million times, claims to show a nurse at Gaza's Al-Shifa hospital speak out against Hamas.
The woman in the video doesn't appear to have an accent from Gaza, the sound of explosions seems fake, and real staff at Al-Shifa don't seem to know her.
The video, viewed 760,000 times, claims to show Israeli soldiers inside a Hamas tunnel.
The video isn't current and is unrelated to the ongoing conflict. It was posted to Twitter back in August.
Jackson Hinkle claims the Lebanese Hezbollah has newly published this video of its anti-ship missiles in reaction to US aircraft carriers in eastern Mediterranean.
The video was first published in August 2019. It's not current.
This graphic image doesn't show the 1948 Deir Yassin massacre.
This is a photo of the bodies of prisoners killed by the Nazis at the Mittelbau-Dora concentration camp in Nordhausen, taken after its liberation by US troops in 1945.
This image of an Israeli air strike in Gaza, tweeted by Jackson Hinkle and viewed 750,000 times, is from the previous Israel-Hamas war in May 2021, not now.
The strike reportedly targeted the Ansar compound, linked to Hamas.
