Etherscan Phishing Crisis: Malicious Ads Drain Cryptocurrency Wallets

Etherscan, an Ethereum blockchain explorer, has been compromised by a large-scale phishing campaign involving malicious advertisements. These advertisements redirect users to fake websites that can drain their crypto wallets. The phishing campaign extends beyond Etherscan to search engines and social media platforms, with Angel Drainer, a known cyber phishing organization, suspected to be responsible. Despite warnings from security experts, the lack of oversight from advertisement aggregators is believed to be the root cause of this widespread attack.

Etherscan's Phishing Epidemic: A Comprehensive Analysis

, April 8, 2023

A pervasive phishing campaign has compromised the integrity of Etherscan, the Ethereum blockchain explorer, leaving its users vulnerable to malicious actors. Advertisements embedded within the platform have been instrumental in diverting unsuspecting victims to fraudulent websites designed to drain their cryptocurrency wallets.

Initial Detection and Escalation

The initial alarm was raised by McBiblets, an astute community member, who identified multiple advertisements on Etherscan as potential vectors for wallet compromise. He cautioned users against clicking on these advertisements, warning of the risk of being redirected to phishing websites.

Thorough investigations revealed that these malicious advertisements were not isolated to Etherscan but were also present on numerous known phishing websites. Scam Sniffer, a prominent Web3 anti-scam platform, meticulously traced the origins of the advertisements, confirming that they spread beyond Etherscan's domain and reached popular search engines, including Google, Bing, and DuckDuckGo, and even surfaced on social media platforms like X.

Root Cause Analysis

Scam Sniffer pinpointed the lack of oversight from advertisement aggregators as the underlying cause of the widespread phishing campaign. Etherscan sources its advertisements from platforms such as Coinzilla and Persona, and insufficient filtering mechanisms within these platforms enable phishing attempts to slip through unchecked.

The Modus Operandi of Wallet Drainers

The wallet drainer scams employed by these malicious actors are cunningly designed to lure users to counterfeit websites and prompt them to connect their cryptocurrency wallets. Once the connection is established, the scammer gains unfettered access to the user's funds, enabling them to withdraw funds into their own personal wallet addresses without any form of user authentication or consent.

Blockchain Security Experts Issue Warnings

Blockchain security firm SlowMist's chief information security officer, 23pds, echoed the warnings about the phishing advertisements on Etherscan. He urged vigilance, cautioning users to be wary of suspicious advertisements.

Suspect Organization and Lack of Concrete Evidence

While suspicions point towards the notorious cyber phishing organization, Angel Drainer, as the perpetrator behind the ongoing phishing attack campaign against Etherscan users, concrete evidence remains elusive at this time.

Escalating Crypto Phishing Epidemic

The Etherscan phishing epidemic underscores the escalating threat posed by crypto phishing attacks. In 2023 alone, these malicious campaigns have pilfered nearly $300 million from over 324,000 victims, according to alarming statistics provided by Cointelegraph.

Notable wallet drainers active in 2023 include:

• Omega Drainer
• Blue Panther Drainer
• Strong Drainer
• Tusk Drainer

Phishing Gangs Exploit Lax Enforcement

Scam Sniffer's investigation uncovered a disturbing trend: even when malicious actors close down their phishing operations, "phishing gangs" simply relocate their activities to other platforms. Evidently, there is no shortage of unscrupulous providers supplying services to these scammers, which highlights the urgent need for enhanced enforcement and regulation in the digital landscape.
