The $540 million hack of Axie Infinity's Ronin Bridge in late March 2022 was the consequence of one of its former employees getting tricked by a fraudulent job offer on LinkedIn, it has emerged.

According to a report from The Block published last week citing two people familiar with the matter, a senior engineer at the company was duped into applying for a job at a non-existent company, causing the individual to download a fake offer document disguised as a PDF.

"After what one source described as multiple rounds of interviews, a Sky Mavis engineer was offered a job with an extremely generous compensation package," the Block reported.

The offer document subsequently acted as a conduit to deploy malware designed to breach Ronin's network, ultimately facilitating one of the crypto sector's biggest hacks to date.

"Sky Mavis employees are under constant advanced spear-phishing attacks on various social channels and one employee was compromised," the company said in a post-mortem analysis in April.

"This employee no longer works at Sky Mavis. The attacker managed to leverage that access to penetrate Sky Mavis IT infrastructure and gain access to the validator nodes."

In April 2022, the U.S. Treasury Department implicated the North Korea-backed Lazarus Group in the incident, calling out the adversarial collective's history of attacks targeting the cryptocurrency sector to gather funds for the hermit kingdom.

Bogus job offers have been long employed by the advanced persistent threat as a social engineering lure, dating back as early as August 2020 to a campaign dubbed by Israeli cybersecurity firm ClearSky as "Operation Dream Job."

In its T1 Threat Report for 2022, ESET noted how actors operating under the Lazarus umbrella have employed fake job offers through social media like LinkedIn as its strategy for striking defense contractors and aerospace companies.

While Ronin's Ethereum bridge was relaunched in June, three months after the hack, the Lazarus Group is also suspected to be behind the recent $100 million altcoin theft from Harmony Horizon Bridge.

The findings also come as blockchain projects centered around Web 3.0 have lost more than $2 billion to hacks and exploits in the first six months this year, blockchain auditing and security company CertiK disclosed in a report last week.

Hackers Used Fake Job Offer to Hack and Steal $540 Million from Axie Infinity

This is a post from HackRead.com Read the original post: Hackers Used Fake LinkedIn Job Offer to Hack Off $625M from Axie Infinity

****Earlier in March this year, Ronin Network (RON), a blockchain network underpinning the famous crypto game Axie Infinity and Axie DAO suffered the largest crypto hack against a decentralized finance network reported to date.****

In May 2022, the United States issued an advisory according to which highly skilled hackers from North Korea were trying to get employed by posing as IT freelancers. Now, it has been revealed that Axie Infinity hacking was socially engineered in which North Korean government-backed hacker group Lazarus used a fake job offer to infiltrate Sky Mavis’ network by sending one of the company’s employees a PDF file containing spyware.

Lazarus’ involvement in such a high-profile hack should not come as a surprise. In January 2022, researchers from different crypto security firms concluded that North Korean hackers have so far stolen $1.3 billion from cryptocurrency exchanges across the globe, while their prime suspect in these hacks was the infamous Lazarus gang.

**Axie Infinity Hack**

The employee, an ex-senior engineer at the company, took the bait and thought that it was a high-paying job offer from another company and opened the PDF. However, in reality, this company didn’t exist. During the recruiting process, the ex-employee gave away critical personal information, which attackers used to steal from the company.

Sky Mavis explained that its employees are constantly threatened by “advanced spear-phishing attacks on various social channels.” In this instance, one employee was fooled, who doesn’t even work at Sky Mavis anymore.

It is worth noting that the play-to-earn game Axie Infinity is a Pokemon-inspired game developed by Sky Mavis and rakes in approximately $15 million in revenue daily.

**How was Ronin Hacked?**

According to The Block, when the hacking took place, Axie Infinity had nine validators from its proof-of-authority, an Ethereum-based sidechain Ronin.

“The attacker managed to leverage that access to penetrate Sky Mavis IT infrastructure and gain access to the validator nodes,” Sky Mavis stated.

The attacker had to capture five out of nine validators to infiltrate the company’s networks. The spyware-laced PDF helped the attacker control 4 validators and access the community-run Axie DAO (Decentralized Autonomous Organization), from where they got control of the 5th validator.

After compromising the network, the attackers stole $25 million worth of USDC stablecoin and 173,600 ether (roughly $597 million) from Axie Infinity’s treasury, collectively stealing crypto worth around $625 million.

Nevertheless, Ronin sidechain increased the number of validators to 11 to enhance security, whereas Sky Mavis is reimbursing Axie Players who lost crypto due to the attack. The company underwent a $150 million funding round back in April 2022.

**Lazarus Hackers**

The US government claims that the notorious North Korean hacker group Lazarus is responsible for the attack. This group specializes in such attacks.

This isn’t the first time that Lazarus has targeted the blockchain industry. However, this is uncommon for Lazarus to use social engineering to invade a company’s networks. In fact, in June 2020, Slovak internet security company ESET warned LinkedIn users of Lazarus’ involvement in a sophisticated LinkedIn recruiter scam targeting military and aerospace firms.

Hackers Used Fake LinkedIn Job Offer to Hack Off $625M from Axie Infinity

Bogus job offers and unrevoked permissions are to blame for a massive crypto-heist which took place earlier this year.
The post Fake job offer leads to $600 million theft appeared first on Malwarebytes Labs.

Back in March, popular NFT battler Axie Infinity lay at the heart of a huge cryptocurrency theft inflicted on the Ronin network. From the Ronin newsletter:

> There has been a security breach on the Ronin Network. Earlier today, we discovered that on March 23rd, Sky Mavis’s Ronin validator nodes and Axie DAO validator nodes were compromised resulting in 173,600 Ethereum and 25.5M USDC drained from the Ronin bridge in two transactions. The attacker used hacked private keys in order to forge fake withdrawals. We discovered the attack this morning after a report from a user being unable to withdraw 5k ETH from the bridge.

These validator nodes act as a means to prevent criminals making off with lots of money. In order to put together a bogus transaction, they’d need to gain access to 5 out of 9 validator nodes. The successful attack happened over 2 stages.

An unwary employee provided one foot in the door. An unrevoked permission elsewhere kicked it wide open.

**The trap is set**

According to The Block, everything fell into place thanks to a senior engineer at the game developer. Two inside sources claim the engineer was fooled by a fake job offer. In fact, it seems multiple employees were approached and encouraged to put in applications. Scams originating from LinkedIn accounts are popular at the moment. As it happens, this is where scammers tried to persuade various people on the development team.

One individual is all it took to empty out a big slice of cryptocurrency funds. A job offer made after several interviews was enough to convince the victim to get on board. Perhaps the “extremely generous” compensation package offered should have set off some alarm bells. Having said that, anything digital finance related likely has huge amounts of cash available.

**We rate this job offer a 4 out of 5**

Unbeknownst to the engineer, everything came crashing down once they received the job offer. A booby-trapped PDF granted the attackers access to Ronin systems, and they were able to compromise 4 out of the required 5 nodes.

Just one node remained to be compromised. How did they do it?

Step up to the plate, non-revoked access. When employees leave an organisation, it’s a good idea to remove access to networks and devices. Unknown entities will happily make use of unattended credentials or permissions. Sure enough, that’s what happened here.

**Nudging a node**

A Decentralised Autonomous Organization (DAO) is a way for people in a community to make decisions on a project. The developers approached an Axie DAO for assistance with transactions in November 2021. Ultimately, this is where the fifth node compromise starts to take shape. The issue isn’t that the DAO exists. The issue is the permissions granted to the DAO.

From the Substack post detailing the attack:

> At the time, Sky Mavis controlled 4/9 validators, which would not be enough to forge withdrawals. The validator key scheme is set up to be decentralized so that it limits an attack vector, similar to this one, but the attacker found a backdoor through our gas-free RPC node, which they abused to get the signature for the Axie DAO validator.  
> 
> This traces back to November 2021 when Sky Mavis requested help from the Axie DAO to distribute free transactions due to an immense user load. The Axie DAO allowlisted Sky Mavis to sign various transactions on its behalf. This was discontinued in December 2021, but the allowlist access was not revoked.

**Who takes the blame?**

In April, the US Department of Treasury pinned this one on North Korean hacking group Lazarus. Research elsewhere details Lazarus attacks on both the aerospace and defence sector involving bogus job posts. There’s no mention of those attacks having any connection to what happened above. However, the research does highlight further recruitment scams using LinkedIn as the starting point.

Whether you’re operating in a cryptocurrency / web3 realm or not, forgotten permissions could cost you dearly. There’s also the fake job offer approach to consider, too. In recent months we’ve seen other game developers targeted. Deepfakes are now worming their way into the bogus job scene. Malware is rife in this sort of operation, so please be cautious around any promising new offer.

Threat actor released decryption keys after abandoning malware to focus on cryptojacking

Adam Bannister 08 July 2022 at 15:40 UTC

Threat actor released decryption keys after abandoning malware to focus on cryptojacking

Malware protection specialist Emsisoft has released free decryption tools for the AstraLocker and Yashma ransomware variants.

The decryptors were recently uploaded to the VirusTotal malware analysis platform by the ransomware’s developer after they reportedly shut down their operation in order to pivot to cryptojacking.

The AstraLocker decryptor and Yashma decryptor join a host of other decryptors made available for free by Emsisoft, a New Zealand-based outfit.

**Using the decryptor**

“Be sure to quarantine the malware from your system first, or it may repeatedly lock

your system or encrypt files,” reads a guide (PDF) on how to use the AstraLocker tool.

For systems compromised via Windows Remote Desktop, users are advised to change passwords for all users permitted to login remotely and check local user accounts for additional accounts the attacker might have added.

Catch up with the latest ransomware news and attacks

By default, the AstraLocker decryptor pre-populates locations selected for decryption from network and connected drives, but users can add other locations before initiating the decryption process.

The decryptor also defaults to leaving encrypted files in place, although users can enable automatic deletion if disk space is an issue.

“Since the ransomware does not save any information about the unencrypted files, the decryptor can’t guarantee that the decrypted data is identical to the one that was previously encrypted,” the guide warns.

**BabyK offspring**

AstraLocker, which emerged in 2021, is seemingly built on Babuk (or BabyK), a variant deployed via a ransomware-as-a-service (RaaS) model, according to a ReversingLabs analysis of the latter’s leaked source code.

Files are encrypted using a modified HC-128 encryption algorithm and Curve25519 cryptographic function, and or extensions are appended to encrypted files.

Yashma – or ‘AstraLocker 2.0’ – harnesses AES-128 and RSA-2048 to encrypt files and appends encrypted files with the extension or a random four-character alphanumeric combination.

According to ReversingLabs, AstraLocker 2.0 is smuggled into networks via malicious Microsoft Office files.

This ‘smash and grab’ attack methodology is suggestive of a low-skill threat actor, argued Joseph Edwards, senior malware researcher at ReversingLabs.

“This underscores the risk posed to organizations following code leaks like that affecting Babuk, as a large population of low-skill, high-motivation actors leverage the leaked code for use in their own attacks.”

A radio control system for drones is vulnerable to remote takeover, thanks to a weakness in the mechanism that binds transmitter and receiver.

A radio control system for drones is vulnerable to remote takeover, thanks to a weakness in the mechanism that binds transmitter and receiver.

The popular protocol for radio controlled (RC) aircraft called ExpressLRS can be hacked in only a few steps, according to a bulletin published last week.

ExpressLRS is an open-source long range radio link for RC applications, such as first-person view (FPV) drones. “Designed to be the best FPV Racing link,” wrote its authors on Github. According to the report the hack utilizes “a highly optimized over-the-air packet structure, giving simultaneous range and latency advantages.”

The vulnerability in the protocol is tied to the fact some of the information sent over via over-the-air packets is link data that a third-party can use to hijack the connection between drone operator and drone.

Anyone with the ability to monitor traffic between an ExpressLRS transmitter and receiver can hijack the communication, which “could result in full control over the target craft. An aircraft already in the air would likely experience control issues causing a crash.”

****Weakness in Drone Protocol** **

The ExpressLRS protocol utilizes what is called a “binding phrase,” a kind of identifier that ensures the correct transmitter is talking to the correct receiver. The phrase is encrypted using MD5 – a hashing algorithm that’s been considered broken (PDF) for nearly a decade. As noted in the bulletin, “the binding phrase is not for security, it is anti-collision,” and security weaknesses associated with the phrase could allow an attacker to “extract part of the identifier shared between the receiver and transmitter.”

The core of the problem is tied to the “sync packets” – data communicated between transmitter and receiver at regular intervals to ensure they are synced up. These packets leak much of the binding phrase’s unique identifier (UID) – specifically, “75% of the bytes required to take over the link.”

That leaves only 25% – only one byte of data – left open. At this point, the report author explained, the remaining bit of the UID can be brute forced, or gathered “by observing packets over the air without brute forcing the sequences, but that this can be more time consuming and error prone.”

If an attacker has the UID in hand, they can connect with the receiver – the target aircraft – and take at least partial control over it.

The author of the bulletin recommended the following actions be taken, to patch over the vulnerabilities in ExpressLRS. Do not send the UID over the control link. The data used to generate the FHSS sequence should not be sent over the air. Improve the random number generator. This could involve using a more secure algorithm, or adjusting the existing algorithm to work around repeated sequences.
