Pharming Attack: How attackers use fake websites to steal data

Image
Pharming definition A pharming attack tries to redirect a website's traffic to a fake website controlled by the attacker, usually for the purpose of collecting sensitive information from victims or installing malware on their machines. Attackers tend to focus on creating look-alike eCommerce and digital banking websites to harvest credentials and payment card information. How pharming attacks work Though they share similar goals, pharming uses a different method from phishing. “Pharming attacks are focused on manipulating a system, rather than tricking individuals into going to a dangerous website,” explains David Emm, a principal security researcher at Kaspersky. “When either a phishing or pharming attack is completed by a criminal, they have the same driving factor to get victims onto a corrupt location, but the mechanisms in which this is undertaken are different.” Pharming attacks involve redirecting user requests by manipulating the Domain Name Service (DNS) protocol...

Marriott Data Breach of 5.2 Million customers

Image
Marriott has confirmed a second data breach in three years — this time involving the personal information on 5.2 million guests. The hotel giant said Tuesday it discovered in late February the breach of an unspecified property system at a franchise hotel. The hackers obtained the login details of two employees, a hotel statement said and broke in weeks earlier during mid-January. Marriott said it has “no reason” to believe payment data was stolen but warned that names, addresses, phone numbers, loyalty member data, dates of birth and other travel information — such as linked airline loyalty numbers and room preferences — were taken in the breach. Starwood, a subsidiary of Marriott, said in 2018 its central reservation system was hacked, exposing the personal data and guest records on 383 million guests. The data included five million unencrypted passport numbers and eight million credit card records. It prompted a swift response from European authorities, which issued Marrio...
