Russian Hacker Pleads Guilty to Operating Kelihos Botnet

Sep 13, 2018
The Russian man who was accused of operating the infamous Kelihos botnet has finally pleaded guilty in a U.S. federal court. Peter Yuryevich Levashov , 38, of St. Petersburg, Russia, pleaded guilty on Wednesday in U.S. federal court in Connecticut to computer crime, wire fraud, conspiracy and identity theft charges. Levashov, also known by many online aliases including Peter Severa, Petr Levashov, Petr Severa and Sergey Astakhov, has admitted of operating several botnets, including the Storm, Waledac and Kelihos botnets, since the late 1990s until he was arrested in April 2017 . Kelihos botnet, dated back to 2010, was a global network of tens of thousands of infected computers that were used to steal login credentials, send bulk spam emails, and infect computers with ransomware and other malware.

Spanish Court Agrees to Extradite Russian Spam King to the United States

Spanish Court Agrees to Extradite Russian Spam King to the United States

Oct 05, 2017
Spain's National Court ruled on Tuesday to extradite a 36-year-old Russian computer programmer, accused by American authorities of malicious hacking offences, to the United States, according to a court document. Peter Yuryevich Levashov , also known as Peter Severa, was arrested in April this year when he was travelling with his family to Barcelona, Spain from his home in Russia—a country without an extradition treaty with the United States—for his role in a huge computer botnet. However, since Levashov has previously worked with for Vladimir Putin's United Russia Party for ten years, he fears that the US authorities would torture him for information about his political work if sent there to face the charges against him. " If I go to the U.S., I will die in a year. They want to get information of a military nature and about the United Russia party ," RIA news agency quoted Levashov as saying. " I will be tortured, within a year I will be killed, or I wil...
U.S. Takes Down Kelihos Botnet After Its Russian Operator Arrested in Spain

U.S. Takes Down Kelihos Botnet After Its Russian Operator Arrested in Spain

Apr 11, 2017
A Russian computer hacker arrested over the weekend in Barcelona was apparently detained for his role in a massive computer botnet, and not for last year's US presidential election hack as reported by the Russian media. Peter Yuryevich Levashov, 32-years-old Russian computer programmer, suspected of operating the Kelihos botnet — a global network of over 100,000 infected computers that was used to deliver spam, steal login passwords, and infect computers with ransomware and other types of malware since approximately 2010, the U.S. Justice Department announced Monday. As suspected earlier, Levashov, also known as Peter Severa, is the same man who has also been listed in the World's Top 10 Worst Spammers maintained by anti-spam group Spamhaus , which has given him the 7th position in the list. The arrest was made possible after the FBI learned just last month that Levashov was traveling with his family to Spain from his home in Russia, a country without any extraditi...

Between Buzz and Reality: The CTEM Conversation We All Need

Between Buzz and Reality: The CTEM Conversation We All Need

Jun 24, 2025Threat Exposure Management
I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...
