Federal prosecutors have linked the theft of $150 million in cryptocurrency from a crypto platform to the 2022 LastPass breaches. The hackers allegedly exploited vulnerabilities exposed in the LastPass hacks to steal a developer's decryption key, ultimately gaining access to the crypto platform's "hot" wallets. The indictment doesn't name the victimized crypto platform, but describes it as a "virtual currency exchange based in the United States." Two individuals, Russian national Ruslan Akhmetshin and an unnamed co-conspirator, are charged with money laundering and conspiracy to commit computer fraud. The indictment details Akhmetshin's alleged role in converting the stolen cryptocurrency into Bitcoin and then routing it through various channels to obscure its origin.
Huntress Labs researchers uncovered a campaign where Russian-speaking actors impersonated the Electronic Frontier Foundation (EFF) to distribute the Stealc information-stealing malware. Using a fake EFF domain and mimicking the organization's visual branding, the attackers lured victims with promises of privacy-enhancing tools, instead delivering a malicious installer. This installer deployed Stealc, designed to pilfer sensitive data like passwords, cookies, and cryptocurrency wallet information. The campaign leveraged the legitimate cloud storage service MEGA and utilized Pyramid, a new command-and-control framework, to manage infected machines. This represents a concerning trend of threat actors exploiting trusted organizations to distribute increasingly sophisticated malware.
Hacker News users discussed the sophistication of the Stealc malware operation, particularly its use of Telegram for command-and-control and its rapid iteration to incorporate features from other malware. Some questioned the attribution to Russian actors solely based on language, highlighting the prevalence of Russian speakers in the cybersecurity world regardless of nationality. Others pointed out the irony of using "EFF" in the impersonation, given the Electronic Frontier Foundation's focus on privacy and security. The effectiveness of the multi-stage infection process, including the use of legitimate services like Discord and Telegram, was also noted. Several commenters discussed the blog post's technical depth, appreciating the clear explanation of the malware's functionality and the investigation process. Finally, some users expressed skepticism about the actual impact of such malware, suggesting the targets are likely low-value and the operation more opportunistic than targeted.

The technical implementation was also debated, with commenters discussing the potential for encoding information across both codes for redundancy or error correction, and the challenges of displaying two codes clearly on physical media. Several commenters suggested alternative approaches, such as using a single QR code that redirects to a page containing multiple links, or leveraging NFC technology. The overall sentiment leaned towards skepticism about the necessity and security of the dual QR code approach.
DoubleClickjacking is a clickjacking technique that tricks users into performing unintended actions by overlaying an invisible iframe containing an ad over a legitimate clickable element. When the user clicks what they believe to be the legitimate element, they actually click the hidden ad, generating revenue for the attacker or redirecting the user to a malicious site. This exploit leverages the fact that some ad networks register clicks even if the ad itself isn't visible. DoubleClickjacking is particularly concerning because it bypasses traditional clickjacking defenses that rely on detecting visible overlays. By remaining invisible, the malicious iframe effectively hides from security measures, making this attack difficult to detect and prevent.
Hacker News users discussed the plausibility and impact of the "DoubleClickjacking" technique described in the linked article. Several commenters expressed skepticism, arguing that the described attack is simply a variation of existing clickjacking techniques, not a fundamentally new vulnerability. They pointed out that modern browsers and frameworks already have mitigations in place to prevent such attacks, like the X-Frame-Options header. The discussion also touched upon the responsibility of ad networks in preventing malicious ads and the effectiveness of user education in mitigating these types of threats. Some users questioned the practicality of the attack, citing the difficulty in precisely aligning elements for the exploit to work. Overall, the consensus seemed to be that while the described scenario is technically possible, it's not a novel attack vector and is already addressed by existing security measures.
Brian Krebs's post details how a single misplaced click cost one cryptocurrency investor over $600,000. The victim, identified as "Nick," was attempting to connect his Ledger hardware wallet to what he thought was the official PancakeSwap decentralized exchange.
