The British Army's Twitter and YouTube accounts were hacked and started publicly shilling non-fungible tokens (NFTs) on Sunday (UK time).
The Twitter account started retweeting a number of posts promoting NFTs on its timeline, after swapping out its biography and profile picture to make it appear there was an association with The Possessed NFT collection.
The account's pinned tweet linked users to a fake NFT minting website, according to The Verge.
Meanwhile, the Army's YouTube account was renamed Ark Investment, which shared videos about cryptocurrencies.
The issue was eventually resolved and the army regained control of the accounts.
"The breach of the Army's Twitter and YouTube accounts that occurred earlier today has been resolved and an investigation is underway," the UK Ministry of Defence wrote on Twitter.
"The Army takes information security extremely seriously and until their investigation is complete it would be inappropriate to comment further."
Unsurprisingly, the news caused some mirth on social media.
"British Army general: 'we should build an army that can face Russia'. British Army Twitter and YouTube: hacked for ETH and NFTs," one wrote.
"Love it when our army's twitter gets hacked. Can't wait for them to announce the 'British Army Victory Rerun World Tour'," wrote another.
However, some users pointed out that perhaps there was a more serious side to the hacking.
"OK the British army getting their socials hacked by crypto clowns is pretty funny," one wrote.
"But on the other hand it shows how unprepared our defence forces are in terms of cybersecurity which is especially concerning in our digital age."
Another suggested the Army needed to spend more money on cybersecurity, suggesting it was "not a good look".
A third was more succinct. "These people are responsible for nukes," they wrote.
