Welcome to the latest edition of Pardon The Intrusion, TNW’s bi-weekly newsletter in which we explore the wild world of security.
Ransomware is spreading like wildfire in the US. At least 1,040 schools have been victimized in 2019 alone.
That is when baddies aren’t busy targeting city governments, insurance firms, data centers, technology and healthcare companies. Last week, New Orleans became the latest victim, with the city declaring a state of emergency after its network was breached.
Meanwhile, some companies, including hospital network Hackensack Meridian Health and Canada’s laboratory diagnostics service provider LifeLabs, have opted to pay up the ransom to recover access to locked systems.
“Ransomware attacks are a tried and tested method to get money for adversaries as they find it very lucrative,” says Eric Cornelius, Chief Product Officer at BlackBerry Cylance.
But the question of whether or not to pay a ransom doesn’t come with easy answers.
“We would not be negotiating ransoms if the threat were to manifest physically,” tells Ryan Kalember, who leads cybersecurity strategy for California-based enterprise security solutions provider Proofpoint. “Insurance has changed the economics in favor of the attackers.”
But just as enterprises are beginning to adopt a backup strategy and not yield to ransom demands, criminals are adapting their strategy by collecting and stealing a victim’s data before encrypting files.
As if that wasn’t enough, attackers have come up with another ploy to make infected companies pay up: threaten with mass data exposure.
“One ransomware gang has now created a public Web site identifying recent victim companies that have chosen to rebuild their operations instead of quietly acquiescing to their tormentors,” reported independent security researcher Brian Krebs.
This public naming and shaming marks an escalation of the criminals’ tactics, although it’s not entirely unexpected.
Ultimately, what cannot be denied is that companies and public entities can no longer afford to be lax about erecting security defenses to thwart such attacks from happening in the first place.
Do you have a burning cybersecurity question, or a privacy problem you need help with? Drop them in an email to me, and I’ll discuss it in the next newsletter! Now, onto more security news.

Throughout this year, phishing attacks have mutated in various insidious forms, so much so that they’ve reached new levels of “creativity and sophistication.” Telemetry data gathered by Google shows that malware-infested sites have become a relatively rare phenomenon when compared to phishing sites. According to the company’s Safe Browsing report, the number of detected phishing sites rose to 1,694,944 in December 2019 from a mere 117,538 in early 2015.
Takeaway: Cybersecurity expert The Gruqg once said on Twitter: “Give a man an 0day and he’ll have access for a day, teach a man to phish and he’ll have access for life.” The continuing evolution of the attempts to trick users into revealing their private information only shows the stealthy nature of these scams: “The longer phishers can quietly hide from security solutions, the more chances they have to invade inboxes and trick people into divulging sensitive information.”
