Weaponized Trading Bots Drain $1M From Crypto Users via AI-Generated YouTube Scam

[ad_1]

Over $1 million has been siphoned from unsuspecting crypto customers by means of malicious good contracts posing as MEV buying and selling bots, in accordance with a brand new report by SentinelLABS.

The marketing campaign leveraged AI-generated YouTube movies, aged accounts, and obfuscated Solidity code to bypass fundamental consumer scrutiny and achieve entry to crypto wallets.

Scammers seemed to be utilizing AI-generated avatars and voices to cut back manufacturing prices and scale up video content material.

These tutorials are revealed on aged YouTube accounts populated with unrelated content material and manipulated remark sections to provide the phantasm of credibility. In some circumstances, the movies are unlisted and sure distributed via Telegram or DMs.

At the middle of the rip-off was a wise contract promoted as a worthwhile arbitrage bot. Victims had been instructed via YouTube tutorials to deploy the contract utilizing Remix, fund it with ETH, and name a “Start()” perform.

In actuality, nonetheless, the contract routed funds to a hid, attacker-controlled pockets, utilizing methods similar to XOR obfuscation (which hides information by scrambling it with one other worth) and enormous decimal-to-hex conversions (which convert giant numbers into wallet-readable deal with codecs) to masks the vacation spot deal with (which makes fund restoration trickier).

The most profitable recognized deal with — 0x8725…6831 — pulled in 244.9 ETH ( roughly $902,000) via deposits from unsuspecting deployers. That pockets was linked to a video tutorial posted by the account @Jazz_Braze, nonetheless stay on YouTube with over 387,000 views.

“Each contract sets the victim’s wallet and a hidden attacker EOA as co-owners,” SentinelLABS researchers famous. “Even if the victim doesn’t activate the main function, fallback mechanisms allow the attacker to withdraw deposited funds.”

As such, the rip-off’s success has been broad however uneven. While most attacker wallets netted 4 to 5 figures, just one (tied to Jazz_Braze) cleared over $900K in worth. Funds had been later moved in bulk to secondary addresses, more likely to additional fragment traceability.

Meanwhile, SentinelLABS warns customers to keep away from deploying “free bots” marketed on social media, particularly these involving guide good contract deployment. The agency emphasised that even code deployed in testnets must be reviewed completely, as comparable techniques can simply migrate throughout chains.
