Ransomware backup provider Exagrid pays $2.6m to ransomware attackers

The ransom was paid in bitcoin on May 13. Accession to the ransomware attacker’s demands was made more embarrassing when the backup appliance supplier – which makes a big play of its strengths against ransomware – accidentally deleted the decryption tool and had to ask for it again. The ransomware group, Conti, who had lurked inside the Exagrid network for over a month, revealed they had over 800 gigabytes of personal data of clients and employees, commercial contracts, NDA forms, financial data, tax returns and source code. The initial ransom demanded was $7,480,000 but was negotiated down to $2.6 million.


TikTok quietly updates its privacy policy to collect users’ biometric data

The change allows it to automatically collect information such as faceprints and voiceprints from the content its users post on the platform. The company’s privacy policy notes that it may collect information about “the nature of the audio, and the text of the words spoken in your User Content” for, among other things, content moderation, demographic classification, for content and ad recommendations, and for other non-personally-identifying operations.” Unless a user’s state of country has pre-existing laws preventing such collection, users are seen as consenting by agreeing to the app’s terms of service.

US recovers millions in cryptocurrency paid to Colonial Pipeline ransomware hackers

This follows the attack which prompted the shutdown of the key East Coast pipeline last month. The Justice Department is expected on Monday to announce details of the operation led by the FBI with the cooperation of the Colonial Pipeline operator, people briefed on the matter said. Though paying the ransom to restore operations, behind the scenes, the company had taken steps to notify the FBI and followed instructions that helped investigators track the payment to a cryptocurrency wallet used by the hackers, believed to be based in Russia. CNN earlier reported that federal agencies are adept at tracing currency used to pay ransomware groups, but its ability to effectively do so “situationally dependent” and relies a great deal on how the ransomware organizations manage their operational network.

47% phishing increase in first quarter of 2021

PhishLabs identified 47% more phishing sites in Q1 of 2021 than there were in Q1 of 2020. This trend is continuing as Q2 attacks are also up significantly year-over-year.

Accounts used for single sign-on (SSO) were also heavily targeted in Q1, accounting for 40% of overall phishing volume.


Survey finds many workers don’t know emergency procedures

Rave Mobile Safety issued the results of its 2021 Workplace Safety and Preparedness Survey, which indicates that employers remain challenged with how to best protect and communicate with employees both on-site and remotely in a year of unprecedented change.

A third of respondents said they were unsure of emergency plans related to active shooter, cyberattacks/system outages and workplace violence.
