Targeted cyber attacks accounted for 59% of all attacks in the second quarter of this year, up from 47% in the first quarter, a report has revealed.
Data theft remains a top priority for cyber criminals, the report said, accounting for more than half of the attacks in Q2.
Researchers found that 29% of attacks on organisations targeted personal data and attacks on individuals most often targeted account credentials (44%) and payment card information (34%).
Financial gain was the motivation behind 30% of attacks on organisations and 42% of attacks on individuals.
Leigh-Anne Galloway, cyber security resilience lead at Positive Technologies, said: “Companies often store large databases with personal data and credentials of their clients, and criminals are also interested in usernames and passwords of the employees of target companies.
“As for individual users, the public has a bad track record when it comes to securing their accounts. They use weak passwords or re-use passwords across sites, enter passwords for websites without checking their authenticity, and give out information that could help an attacker to guess their password. This is why credentials and payment information are top targets.”
Governments were the targets of 62% of malware infections, up from 44% in the previous quarter, with governments most frequently hit by ransomware, the report said.
Cyber criminals are reportedly focusing ransomware attacks increasingly on local government authorities and enterprises because they are more likely to pay higher ransom demands when normal business operations are crippled. The average ransom demand was $36,000 in the second quarter, according to researchers at security firm McAfee.
Some local authorities have refused to pay ransoms, in line with guidance from law enforcement and cyber security industry representatives, said the Positive Technologies report. But despite ransomware attacks disabling their IT infrastructure, authorities in the US cities of Lake City and Riviera Beach, for example, reportedly paid ransoms of $600,000 and $530,000, respectively.

- Ransomware has seen a resurgence since the start of 2019, with cyber criminals changing code and tactics to target enterprises and local authorities for higher ransom payments, McAfee researchers warn.
- Businesses are increasingly becoming the most popular targets for ransomware, which remains a top cyber threat around the world, especially in the US, a report reveals.
- Vectra 2019 Spotlight report shows recent ransomware attacks cast a wider net to ensnare cloud, datacentre and enterprise infrastructures.
- Despite a global decrease in the volume of malware in the past year, ransomware is surging once again, and the UK is one of the worst-hit countries, a report reveals.
Government-related websites also continue to draw hackers, the report said. In April, three websites of the FBI National Academy Associates were hacked, resulting in the leak of personal data for about 4,000 federal agents and law enforcement personnel.
Healthcare also stood out as a top target of ransomware in the second quarter. By disabling IT systems, ransomware can be especially dangerous with healthcare because it has the potential to harm both the institution and its patients, the report said.
Healthcare employees are on the receiving end of phishing attacks, the report said. It gave the example of a phishing attack aimed at staff of a Nova Scotia clinic in Canada, in which attackers obtained the username and password of an employee, putting the data of nearly 3,000 patients at risk.
“The severity and nature of these attacks against the healthcare industry are particularly alarming,” said Galloway. “However, there are simple ways in which organisations – in healthcare and other sectors – can better protect themselves and the public.
