Mozaic exploited for $2 million, recovers 90%

The "AI-optimized" defi project Mozaic Fi was exploited by an attacker who drained around $2 million in funds from the project.

According to MozaicFi, the theft had been perpetrated by a rogue developer who was able to gain access to a private key held by a core team member. They also claimed that a simultaneous large sale of the Mozaic token resulted in cascading liquidations.

In good news for the project, the attacker moved around 90% of the stolen funds to MEXC, a centralized cryptocurrency exchange that was able to freeze the thief's access to the funds.

Incognito Market drug marketplace pulls multi-million dollar double scam

Since March 5, those who used the Incognito Market darkweb narcotics marketplace have found themselves unable to withdraw the Bitcoin and Monero they had on the platform. It appeared the platform had exit scammed for somewhere between $10 and $30 million.

Making matters worse, on March 10 the website posted a message reading, "Yes, this is an extortion !!" They wrote that, although the platform promised to "auto-encrypt" messages between buyers and sellers, and auto-delete after an expiry date, messages were not encrypted or deleted. They demanded that users pay an additional $100 to $20,000 to have their information removed from the dataset, which they promised to release at the end of May. "Whether or not you and your customers' info is on that list is totally up to you."

The tactic is reminiscent of that of ransomware groups, which often demand double fees: one from victims of hacks first to regain access to their systems, and another in exchange for a promise to destroy stolen data.

Kickstarter's bizarre "pivot to blockchain" spurred by secret $100 million Andreessen Horowitz investment

Web3: a technology so promising you can't even pay a company $100 million to use it.

Crowdfunding website Kickstarter surprised and dismayed many of its users in December 2021 when they announced they would be moving the product to the blockchain in December 2021 for... reasons. That blockchain would just so happen to be the relatively unknown Andreessen Horowitz-backed Celo blockchain. "How this will actually work, beyond Kickstarter being able to yell 'blockchain' like a spell to summon investors ... is unclear," wrote Tom McKay at Gizmodo.

He probably didn't realize how right he was, but now it's been revealed that KickStarter was able to land a $100 million investment from Andreessen Horowitz with handwavy proclamations about the blockchain that its own COO didn't seem to quite understand.

The company seems to have since given up on its blockchain ambitions — in no small part thanks to user revolt. It seems that $100 million windfall didn't include any terms actually requiring Kickstarter to follow through.

Twitter phishers steal over $46 million from 57,000 victims in February

Scam Sniffer's February 2024 report describes 57,000 victims who collectively lost almost $47 million thanks to various phishing schemes on the Twitter platform. Many of the losses came from accounts designed to impersonate various popular cryptocurrency projects, who diverted users to scam websites resembling the real ones.

The largest individual loss was the phishing attack against kirilm.eth, who had over 180 million $BEAM tokens notionally worth over $5 million drained from their crypto wallet. The attacker sold the tokens for around $4.5 million.

The total amount stolen is down slightly from January, in which $55 million was taken. Altogether, scammers have stolen over $100 million via Twitter phishing alone in the first two months of 2024.

Crypto4Winners investment firm claims funds were stolen

A investment firm called Crypto4Winners announced in their Telegram channel that "Our investigations lead us to suspect an individual of committing fraudulent acts that may have compromised the integrity of assets. It is also possible that the current and historical data at our disposal has been tampered with, with a high degree of sophistication."

The company had paused withdrawals the previous day, and has not re-enabled them. They also have not disclosed the amount that was allegedly stolen.

Crypto4Winners claims it has earned 377% returns on customer investments since 2019, producing 3–20% monthly returns.

The company is co-owned by Luc Schiltz, who was sentenced to six years in prison in 2017 for defrauding victims of over $1.5 million through various investment frauds. He was released after two years, and quickly started the Crypto4Winners project after.
