Under Armor announced this week that approximately 150 million users of the diet and fitness app MyFitnessPal had their personal information acquired by an unauthorized third party sometime in February 2018. As Reuters noted, it is the largest data breach of 2018 in terms of the number of records affected.
The breach was discovered on March 25, and the data compromised includes usernames, email addresses, and hashed passwords — the majority of which used bcrypt, the company said.
“The affected data did not include government-issued identifiers (such as Social Security numbers and driver’s license numbers) because we don’t collect that information from users,” the company said in a statement. “Payment card data was not affected because it is collected and processed separately.”
MyFitnessPal also said that it would be requiring users to change their passwords and is urging users to do so immediately. The company is also urging users to review their accounts for suspicious activity as well as to change passwords on any other online accounts that used the same or a similar password to their now-breached MyFitnessPal credentials.
It is unclear how the unauthorized third party acquired the data, and the investigation is ongoing. Under Armour bought MyFitnessPal in February 2015 for $475 million.

Cyber Risk Trends From the Past Week
Law enforcement officials in Spain have arrested the alleged leader of the cybercriminal syndicate behind the Carbankak and Cobalt malware attacks, which have targeted more than 100 financial organizations around the world and caused cumulative losses of over €1 billion since 2013.
Europol’s press release did not name the alleged mastermind behind the group; however, Bloomberg reported that Spain’s Interior Ministry named the suspect as Denis K, a Ukrainian national who had accumulated about 15,000 bitcoins (worth approximately $120 million at the time of his arrest). Europol noted that numerous other coders, mule networks, and money launderers connected to the group were also the target of the international law enforcement operation.
The group first used the Anunak malware in 2013 to target financial transfers and ATM networks, and by the following year they had created a more sophisticated version of the malware known as Carbanak, which was used by the group used until 2016. At that point the group carried out an even more sophisticated wave of attacks using custom-made malware based on the Cobalt Strike penetration testing software, Europol said.
“The criminals would send out to bank employees spear phishing emails with a malicious attachment impersonating legitimate companies,” Europol wrote in a press release. “Once downloaded, the malicious software allowed the criminals to remotely control the victims’ infected machines, giving them access to the internal banking network and infecting the servers controlling the ATMs. This provided them with the knowledge they needed to cash out the money.”
Carlos Yuste, a Spanish police chief inspector who helped lead the operation, told Bloomberg that “the head has been cut off” of the high-profile group. Steven Wilson, Head of Europol’s European Cybercrime Centre, said that the arrest illustrates how law enforcement “is having a major impact on top level cybercriminality.”
