Taiwan was one of the countries worst hit by ransomware attacks last year, falling victim to millions of attacks, according to Trend Micro Inc’s (趨勢科技) annual security roundup.
Global software security company Trend Micro found in its 2017 Annual Security Roundup: The Paradox of Cyberthreats that companies worldwide lost up to US$5 billion due to massive ransomware outbreaks.
That is four times the level recorded in 2016, although the number of ransomware-related threats decreased from 1.078 billion in 2016 to 631 million last year.
Although there were fewer ransomware attacks last year, they had greater impact, the company said.
These included the WannaCry ransomware attack, which is estimated to have affected more than 200,000 computers in 150 countries in May last year.
Taiwan was heavily affected by the malware, with the National Security Bureau reporting that 185 computers were infected.
Other features of last year’s attacks were the tendency to use business e-mail compromises — scams targeting companies in which the hacker impersonates an executive and requests wire transfers or sensitive information via e-mail — and the focus on cryptocurrencies, such as bitcoin.
The growing popularity and profitability of cryptocurrencies has led cybercriminals to target the field, Trend Micro said.
Companies that need to comply with the EU’s newly passed General Data Protection Regulation (GDRP) should double down on cybersecurity measures, as cybercriminals could target them knowing they would have to pay a fine for any instances of leaked data, it said.
Cybercriminals could steal data from such companies and charge a ransom just below the fine they would be required to pay based on the GDRP, it added.
Cybercriminals are developing new ways to make money from cyberattacks — methods that are targeted and specific so they can optimize the profitability of each attack, Trend Micro marketing manager Jon Clay said.
Companies need to protect themselves with the newest versions of cyberprotection software to minimize risks, he added.
Alphabet Inc’s Google on Tuesday announced plans to buy a New York office building for US$2.1 billion, confirming its push into the US’ largest city despite the COVID-19 teleworking trend. This is the largest real-estate purchase in the US for an office building since the beginning of the global spread of COVID-19, the Wall Street Journal quoted Real Capital Analytics as saying. Google already rents the premises in Manhattan, which are located on the site of a former railroad terminal in the Hudson Square neighborhood. The Silicon Valley giant envisions a campus with a total surface area of 160,000m2 by mid-2023
‘CORE VALUES’: The contract chipmaker did not specify why the employees were dismissed, but media reports said they had leaked information about customer orders Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has fired seven of its employees for violating the company’s “core values,” the world’s largest contract chipmaker said yesterday. While the company did not disclose exactly why it fired the seven employees, local media reports earlier in the day said that the employees had leaked confidential information about customer orders. In a statement, the company said that it fired the seven at once, adding that it released an internal notice last week to inform the entire company of the move ahead of the four-day Mid-Autumn Festival holilday, which ended on Tuesday.

MILD ADJUSTMENT: Two previous efforts failed to curtail mortgage financing, although the new measures should not affect property prices, the central bank governor said The central bank yesterday tightened credit controls for second-home mortgages in specific areas and purchases of plots of land, especially in industrial parks. However, the nation’s top monetary policymaker kept its policy rate at a record-low 1.125 percent for the sixth consecutive quarter, despite revising up its GDP growth forecast for this year from 5.08 percent to 5.75 percent. “Board members factored in economic uncertainty at home and around the world,” central bank Governor Yang Chin-long (楊金龍) said, adding that growing inflationary pressure was a temporary phenomenon induced by bad weather and a low base effect for oil prices.

DOWNCYCLE: Most buyers are wary about placing new orders, and although the decline could also be as little as 3%, it would be the first drop since the start of the year The average selling price of DRAM chips next quarter is expected to decline by up to 8 percent quarter-on-quarter, with memory chips used in notebook computers and consumer electronics seeing the steepest decline due to excess inventory and a shortage of components, market researcher TrendForce Corp (集邦科技) said yesterday. That means the DRAM industry is entering a new downcycle after experiencing a boom for three quarters, the longest uptrend in the history of the industry. The Taipei-based researcher said it expects the balance between supply and demand to begin tilting toward a surplus in the final quarter of this year. Most DRAM
