COINTELEGRAPH

DESCRIPTION OF EVENTS

Founded in 2013, Cointelegraph is a privately held company specializing in cryptocurrency, blockchain, and fintech news. Cointelegraph is a leading independent digital media outlet. It delivers daily news, in-depth analysis, and educational content across various topics, including Bitcoin, Ethereum, decentralized finance (DeFi), non-fungible tokens (NFTs), and Web3. The platform is recognized for its comprehensive coverage, featuring expert opinions, price charts, and reports on the social impact of digital currencies.

 

Headquartered in the United States, Cointelegraph has expanded its presence internationally, with teams in over 30 countries. The company publishes more than 1,000 articles monthly and offers a range of resources, such as a mobile app, video content, and educational materials like "Cryptopedia" . Despite its prominence, Cointelegraph has faced criticism over the years for occasional inaccuracies and sensational headlines, which have led to discussions about its editorial practices within the crypto community.

 

In addition to its U.S. headquarters, Cointelegraph has expanded its global presence with offices in various countries, including China, Japan, South Korea, and the United Arab Emirates.

 

Visitors of CoinTelegraph were greeted with a pop-up advertisement which claimed they had been randomly selected to receive a free airdrop of new CTG tokens, with a reported value of $5,490 USD. The user was prompted to connect their wallet, which would likely be drained.

 

According to analysis from realScamSniffer, there was compromised JavaScript code coming from a third-party advertising software called "AdButler" on domain "adbutlerserve.com".

 

It's unclear if the advertising partner was compromised, or CoinTelegraph was tricked into applying JavaScript code which is from a fake advertising company. CoinTelegraph has attributed the failure to their "banner publishing system" being "briefly compromised".

 

It is unknown how many people fell victim to the CoinTelegraph website phishing.

 

After widespread detection and coverage, CoinTelegraph published a notice that they were aware of the issue on their website and working on a resolution.

 

CoinTelegraph was ultimately able to remove the malicious advertisement, and subsequently posted an update to that effect.

 

CoinTelegraph has not publicly offered any assistance for those affected.

 

There is no clarity regarding who was affected by the incident, or what was lost. It is unclear if any investigation is continuing.
