Phishing attack on Altcoin Uniswap
CZ used Twitter to inform Uniswap, which it claims is one of the few tokens listed without any direct contact information. Many appreciated CZ’s commitment to the overall security of the crypto ecosystem. Others criticized his tweet as “highly irresponsible”. As explained later by Uniswap and CZ themselves, the Uniswap protocol was completely secure. The exploit was actually a successful phishing campaign. While CZ apologized for the false alarm, many experts criticized him for such incidents that could cause market panic. AmkNews.com As we reported, Uniswap’s native token UNI has dropped 9 percent in the last 24 hours.

Samczsun, another security expert, described the attempt as a very successful phishing attack. The attacker then used a privacy tool, Tornado Cash, to launder the stolen proceeds.
Experts called CZ irresponsible
Chainlink’s community ambassador, ChainLinkGod.eth, described CZ’s behavior as irresponsible, noting that misinformation spreads very quickly. Frank Chaparro, host of The Scoop Podcast, shared similar sentiments. Panic and fears of misinformation are not unfounded. Great influencers repeated the news that Uniswap was hacked when it was actually a phishing attack. Two major crypto influencers, eth and ap3father, fell into the same trap and urged their followers to avoid using Uniswap.
