Instagram Hack Results in $1 Million Loss in NFTs

Read Time:4 Minute, 12 Second

Imagine – your favorite brand on Instagram just announced a giveaway. You’ll receive a free gift! All you have to do is provide your credit card information. Sounds easy, right? This is a brand you’ve followed and trusted for a while now. You’ve engaged with them and even purchased some of their items. The link comes directly from their official page, so you don’t think to question it. 

This is the same mindset that led to several Bored Ape Yacht Club (BAYC) NFTs being stolen by a cybercriminal who had hacked into the company’s official Instagram account. Let’s dive into the details of this scam.  

Sneaking Into the Bored Ape Yacht Club 

Bored Ape Yacht Club, the NFT collection, disclosed through Twitter that their Instagram account had been hacked, and advised users not to click on any links or link their crypto wallets to anything. The hacker managed to log into the account and post a phishing link promoting an “airdrop,” or a free token giveaway, to users who connected their MetaMask wallets. Those who linked their wallets before BAYC’s warning lost a combined amount of over $1 million in NFTs. 

Despite the large price tag attached to NFTs, they are often held in smartphone wallets rather than more secure alternatives. MetaMask, the crypto wallet application, only allows NFT display through mobile devices and encourages users to use the smartphone app to manage them. While it may be a good method for display purposes, this limitation provides hackers with a new and effective way to easily steal from users’ mobile wallets. 

BAYC does not yet know how the hacker was able to gain access to their Instagram account, but they are following security best practices and actively working to contact the users affected. 

 N.F.T. – Not For Taking 

This scam was conducted through the official BAYC account, making it appear legitimate to BAYC’s followers. It is incredibly important to stay vigilant and know how to protect yourself and your assets from scams like these. Follow the tips below to steer clear of phishing scams and keep your digital assets safe:  

Ensure wallet security 

A seed phrase is the “open sesame” to your cryptocurrency wallet. The string of words is what grants you access to all your wallet’s assets. Ensuring that your seed phrase is stored away safely and not easily accessible by anyone but yourself is the first step to making sure your wallet is secure. 

Protect your privacy 

With all transactional and wallet data publicly available, scammers can pick and choose their targets based on who appears to own valuable assets. To protect your privacy and avoid being targeted, refrain from sharing your personal information on social media sites or using your NFT as a social media avatar. 

Look out for phishing scams 

Phishing scams targeting NFT collectors are becoming increasingly common. Be wary of any airdrops offering free tokens in exchange for your information or other “collectors” doing the same. 

Phishing scams tend to get more sophisticated over time, especially in cases like the Bored Ape Yacht Club where the malicious links are coming straight from the official account. It is always best to remain skeptical and cautious, but when in doubt, here are some extra tips to spot phishing scams: 

Is it written properly? A few spelling or grammar mistakes can be common, but many phishing messages will contain glaring errors that professional accounts or companies wouldn’t make. If you receive an error-filled message or promotion that requires giving your personal information, run in the other direction. 
Does the logo look right? Scammers will often steal the logo of whatever brand or company they’re impersonating to make the whole shtick look more legitimate. However, rarely do the logos look exactly how they’re supposed to. Pay close attention to any logo added in a message or link. Is the quality low? Is it crooked or off-center? Is it almost too small to completely make out? If yes, it’s most likely not the real deal. 
Is the URL legit? In any phishing scam, there will always be a link involved. To check if a link is actually legitimate, copy and paste the URL into a word processor where you can examine it for any odd spelling or grammatical errors. If you receive a strange link via email, hover over it with your mouse to see the link preview. If it looks suspicious, ignore and delete it. Even on mobile devices, you can press and hold the link with your finger to check out the legitimacy of the URL. 

As crypto and NFTs continue to take the world by storm, hackers and scammers are constantly on the prowl for ways to steal and deceive. No matter the source or how trustworthy it may seem at first glance, always exercise caution to keep yourself and your assets safe!

Chinese APT group Winnti stole trade secrets in years-long undetected campaign

Read Time:34 Second

Security researchers have uncovered a cyberespionage campaign that has remained largely undetected since 2019 and focused on stealing trade secrets and other intellectual property from technology and manufacturing companies across the world. The campaign uses previously undocumented malware and is attributed to a Chinese state-sponsored APT group known as Winnti.

“With years to surreptitiously conduct reconnaissance and identify valuable data, it is estimated that the group managed to exfiltrate hundreds of gigabytes of information,” researchers from security firm Cybereason said in a new report. “The attackers targeted intellectual property developed by the victims, including sensitive documents, blueprints, diagrams, formulas, and manufacturing-related proprietary data.”

New Sophisticated Malware

Read Time:1 Minute, 46 Second

Mandiant is reporting on a new botnet.

The group, which security firm Mandiant is calling UNC3524, has spent the past 18 months burrowing into victims’ networks with unusual stealth. In cases where the group is ejected, it wastes no time reinfecting the victim environment and picking up where things left off. There are many keys to its stealth, including:

The use of a unique backdoor Mandiant calls Quietexit, which runs on load balancers, wireless access point controllers, and other types of IoT devices that don’t support antivirus or endpoint detection. This makes detection through traditional means difficult.
Customized versions of the backdoor that use file names and creation dates that are similar to legitimate files used on a specific infected device.
A live-off-the-land approach that favors common Windows programming interfaces and tools over custom code with the goal of leaving as light a footprint as possible.
An unusual way a second-stage backdoor connects to attacker-controlled infrastructure by, in essence, acting as a TLS-encrypted server that proxies data through the SOCKS protocol.

[…]

Unpacking this threat group is difficult. From outward appearances, their focus on corporate transactions suggests a financial interest. But UNC3524’s high-caliber tradecraft, proficiency with sophisticated IoT botnets, and ability to remain undetected for so long suggests something more.

From Mandiant:

Throughout their operations, the threat actor demonstrated sophisticated operational security that we see only a small number of threat actors demonstrate. The threat actor evaded detection by operating from devices in the victim environment’s blind spots, including servers running uncommon versions of Linux and network appliances running opaque OSes. These devices and appliances were running versions of operating systems that were unsupported by agent-based security tools, and often had an expected level of network traffic that allowed the attackers to blend in. The threat actor’s use of the QUIETEXIT tunneler allowed them to largely live off the land, without the need to bring in additional tools, further reducing the opportunity for detection. This allowed UNC3524 to remain undetected in victim environments for, in some cases, upwards of 18 months.

Pro-Ukrainian DoS attack compromises Docker Engine honeypots to target Russian, Belarusian websites

Read Time:37 Second

Researchers from cybersecurity vendor CrowdStrike have detected a denial-of-service (DoS) attack compromising Docker Engine honeypots to target Russian and Belarusian websites amid the ongoing Russia-Ukraine war. According to the firm, the honeypots were compromised four times between February 27 and March 1, 2022, with two different Docker images that both share target lists that overlap with domains reportedly shared by the Ukraine government-backed Ukraine IT Army.

CrowdStrike has therefore linked the attacks to pro-Ukrainian activity against Russia. It has also warned of the risk of retaliatory activity by threat actors supporting the Russian Federation against organizations being leveraged to conduct disruptive attacks against government, military, and civilian websites.
