Our report “2023 Security Outlook” is the final outcome of the weeks’ efforts of reviewing a large volume of information and extracting key messages from it. This will be separately published from the weekend briefing. Please visit our website to read the special report.
Along with our special report, The Readable has picked three news stories that were notable this week. If you have further questions or inquiries, do not hesitate to contact us. Have a great weekend!
1. Taiwanese intelligence agency allegedly hacked
Internal documents of the Taiwanese intelligence agency have allegedly been exposed to cybercriminals and have been put up for sale on an underground forum. On January 11, a dark web user “niceday009” uploaded a series of documents, which the user claimed were stolen from the Taiwanese intelligence agencies, onto BreachForums, where users buy and sell illicitly obtained databases. The 10 gigabytes of data were priced at $150,000.
The user wrote in the sales post that the data includes confidential files of the Taiwanese intelligence agencies, such as sensitive information about their agents and activities, along with the internal information about international cooperation. In a sample file that the user provided as a way to prove the authenticity of the database, personal information about a specific person was indicated, such as family background, personality traits, and political orientation.
According to the Liberty Times, a national newspaper published in Taiwan, the law enforcement of Taiwan acknowledged the incident on January 16 and started an investigation, without disclosing further details. Although there have been several updates to the original post by niceday009, the authenticity of the material has not been verified yet.
“It is very new to see that these dark web actors target Taiwan’s intelligence agencies,” said a cybersecurity researcher who is based in Taiwan and asked to remain anonymous to The Readable. “This threat [by niceday009] has been considered seriously in the Taiwanese cybersecurity industry. The actor claimed that the leaked data has been purchased and he or she prepared the second exposure of leaked data,” added the researcher.
2. Popular South Korean YouTuber fell victim to hacking
Hackers are targeting not only social media accounts of political figures and organizations, but also the accounts and channels of influencers and popular YouTubers. The YouTube channel of South Korean YouTuber with more than 10.8 million subscribers was hacked on Tuesday.
The profile picture, which was once a caricature of the YouTuber herself, was changed to one showing a red and white Tesla logo, according to multiple reports by local news outlets. The name of the channel was changed to “Tesla.” All the videos were deleted and replaced, which appeared to be the three identical live stream videos of Tesla CEO Elon Musk.
The hacked YouTube channel was fixed two days later. The YouTuber uploaded a new video on her restored channel Thursday and left a notice in the comment section, saying that the hacking incident occurred through nothing more than her own carelessness.
3. Ransomware attacks rose 14 times over five years
The number of South Korean companies who reported to the nation’s cybersecurity agency about falling victim to ransomware attacks has increased 14 times over the past five years.
In 2018, 22 South Korean companies, including non-profit organizations, reported to the Korea Internet & Security Agency that they had been hit by ransomware, a cyberattack in which attackers hold victims’ information as hostage through encryption until they are paid.
The cases of ransomware reported to the cybersecurity agency rose gradually, reaching 325 cases last year, which is the highest level in the last five years. South Korean lawmaker Park Wan-joo disclosed this data on Sunday after he had received it from the Ministry of Science and ICT. To read the original reporting, click here.
