A Minnesota cybersecurity and laptop forensics knowledgeable whose testimony has featured in hundreds of courtroom trials over the previous 30 years is dealing with questions on his credentials and an inquiry from the Federal Bureau of Investigation (FBI). Authorized specialists say the inquiry could possibly be grounds to reopen numerous adjudicated instances wherein the knowledgeable’s testimony might have been pivotal.
One may conclude from studying Mr. Lanterman’s LinkedIn profile that has a level from Harvard College.
Mark Lanterman is a former investigator for the U.S. Secret Service Electronics Crimes Process Pressure who based the Minneapolis consulting agency Pc Forensic Providers (CFS). The CFS web site says Lanterman’s 30-year profession has seen him testify as an knowledgeable in additional than 2,000 instances, with expertise in instances involving sexual harassment and office claims, theft of mental property and commerce secrets and techniques, white-collar crime, and sophistication motion lawsuits.
Or at the least it did till final month, when Lanterman’s profile and work historical past have been quietly faraway from the CFS web site. The elimination got here after Hennepin County Legal professional’s Workplace stated it was notifying events to 10 pending instances that they have been unable to confirm Lanterman’s academic and employment background. The county lawyer additionally stated the FBI is now investigating the allegations.
These allegations have been raised by Sean Harrington, an lawyer and forensics examiner primarily based in Prescott, Wisconsin. Harrington alleged that Lanterman lied beneath oath in courtroom on a number of events when he testified that he has a Bachelor of Science and a Grasp’s diploma in laptop science from the now-defunct Upsala Faculty, and that he accomplished his postgraduate work in cybersecurity at Harvard College.
Harrington’s claims gained steam due to digging by the regulation agency Perkins Coie LLP, which is defending a case whereby a consumer’s laptop computer was forensically reviewed by Lanterman. On March 14, Perkins Coie attorneys requested the decide (PDF) to strike Lanterman’s testimony as a result of neither he nor they might substantiate claims about his academic background.
Upsala Faculty, situated in East Orange, N.J., operated for 102 years till it closed in 1995 after a interval of declining enrollment and monetary difficulties. Perkins Coie instructed the courtroom that they’d visited Felician College, which holds the transcripts for Upsala Faculty throughout the years Lanterman claimed to have earned undergraduate and graduate levels. The regulation agency stated Felician had no report of transcripts for Lanterman (PDF), and that his title was absent from the entire Upsala Faculty pupil yearbooks and graduation applications throughout that interval.
Reached for remark, Lanterman acknowledged he had no approach to show he attended Upsala Faculty, and that his “postgraduate work” at Harvard was in actual fact an eight-week on-line cybersecurity class known as HarvardX, which cautions that its certificates shouldn’t be thought of equal to a Harvard diploma or a certificates earned by means of conventional, in-person applications at Harvard College.
Lanterman has testified that his first job after school was serving as a police officer in Springfield Township, Pennsylvania, though the Perkins Coie attorneys famous that this function was omitted from his resume. The attorneys stated once they tried to confirm Lanterman’s work historical past, “the police division responded with a narrative that will be virtually unimaginable to imagine if it was not corroborated by Lanterman’s personal electronic mail communications.”
As recounted within the March 14 submitting, Lanterman was deposed on Feb. 11, and the next day he emailed the Springfield Township Police Division to see if he might have a peek at his previous personnel file. On Feb. 14, Lanterman visited the Springfield Township PD and requested to borrow his employment report. He instructed the officer he spoke with on the cellphone that he’d just lately been instructed to “get his affairs so as” after being recognized with a grave coronary heart situation, and that he wished his previous file to point out his household about his early profession.
In accordance with Perkins Coie, Lanterman left the Springfield Township PD along with his personnel file, and has not returned it as promised.
“It’s stunning that an knowledgeable from Minnesota would journey to suburban Philadelphia and abscond along with his decades-old personnel file to obscure his background,” the regulation agency wrote. “That seems to be the worst and most egregious type of spoliation, and the deception alone is cause sufficient to exclude Lanterman and think about sanctions.”
Harrington initially contacted KrebsOnSecurity about his issues in late 2023, fuming after sitting by means of a convention speech wherein Lanterman shared paperwork from a ransomware sufferer and instructed attendees it was as a result of they’d refused to rent his firm to carry out a forensic investigation on a latest breach.
“He claims he was concerned within the Martha Stewart investigation, the Bernie Madoff trial, Paul McCartney’s divorce, the Tom Petters investigation, the Denny Hecker investigation, and lots of others,” Harrington stated. “He claims to have been invited to talk to the Supreme Courtroom, claims to coach the ‘total federal judiciary’ on cybersecurity yearly, and is a school member of the USA Judicial Convention and the Judicial Faculty — positions which he obtained, partially, on a home of fraudulent playing cards.”
In an interview this week, Harrington stated courtroom paperwork reveal that at the least two of Lanterman’s earlier shoppers complained CFS had held their knowledge for ransom over billing disputes. In a declaration (PDF) dated August 2022, the co-founder of the regulation agency MoreLaw Minneapolis LLC stated she employed Lanterman in 2014 to look at a number of digital units after studying that one in every of their paralegals had a felony fraud historical past.
However the regulation agency stated when it pushed again on a consulting invoice that was far larger than anticipated, Lanterman instructed them CFS would “escalate” its assortment efforts in the event that they didn’t pay, together with “a declare and lien in opposition to the information which is able to lead to a public public sale of your knowledge.”
“All of us have been flabbergasted by Mr. Lanterman’s electronic mail,” wrote MoreLaw co-founder Kimberly Hanlon. “I had by no means heard of any authentic forensic firm threatening to ‘public sale’ off an lawyer’s knowledge, notably realizing that the information is comprised of confidential consumer knowledge, a lot of which is delicate in nature.”
In 2009, a Wisconsin-based manufacturing firm that had employed Lanterman for laptop forensics balked at paying an $86,000 bill from CFS, calling it “extreme and unsubstantiated.” The corporate instructed a Hennepin County courtroom that on April 15, 2009, CFS performed an public sale of its commerce secret data in violation of their confidentiality settlement.
“CFS seen and performed a Public Sale of digital data that was entrusted to them pursuant to the phrases of the engagement settlement,” the corporate wrote. “CFS submitted the very best bid on the Public Sale within the quantity of $10,000.”
Lanterman briefly responded to a listing of questions on his background (and up to date coronary heart analysis) on March 24, saying he would ship detailed replies the next day. These replies by no means materialized. As a substitute, Lanterman forwarded a latest memo he wrote to the courtroom that attacked Harrington and stated his accuser was solely making an attempt to take out a competitor. He has not responded to additional requests for remark.
“Once I attended Upsala, I used to be a commuter pupil who lived with my grandparents in Morristown, New Jersey roughly half-hour away from Upsala Faculty,” Lanterman defined to the decide (PDF) overseeing a separate ongoing case (PDF) wherein he has testified. “With restricted assets, I didn’t take part in campus social occasions, nor did I attend commencement ceremonies. In 2023, I confirmed with Felician College — which maintains Upsala Faculty’s information — that they might not find my transcripts or diploma, a scenario that they indicated was probably attributable to unresolved money-related points.”
Lanterman was ordered to seem in courtroom on April 3 within the case defended by Perkins Coie, however he didn’t present up. As a substitute, he despatched a message to the decide withdrawing from the case.
“I’m 60 years previous,” Lanterman instructed the decide. “I created my enterprise from nothing. I’m finished coping with the likes of people like Sean Harrington. And fairly frankly, I’ve been planning at turning over my enterprise to my youngsters for years. That point has arrived.”
Lanterman’s letter leaves the impression that it was his choice to retire. However in line with an affidavit (PDF) filed in a Florida case on March 28, Mark Lanterman’s son Sean stated he’d made the troublesome choice to ask his dad to step down given all of the destructive media consideration.
Mark Rasch, a former federal cybercrime prosecutor who now serves as counsel to the New York cybersecurity intelligence agency Unit 221B, stated that if an knowledgeable witness is discredited, any defendants who misplaced instances that have been strongly influenced by that knowledgeable’s conclusions at trial might have grounds for attraction.
Rasch stated regulation companies who suggest an knowledgeable witness have an obligation in good religion to vet that knowledgeable’s {qualifications}, realizing that these credentials will likely be topic to cross-examination.
“Federal guidelines of civil process and proof each require specialists to listing each case they’ve testified in as an knowledgeable for the previous few years,” Rasch stated. “A part of that due diligence is pulling up the outcomes of these instances and seeing what the character of their testimony has been.”
Maybe probably the most well-publicized case involving important forensic findings from Lanterman was the 2018 conviction of Stephen Allwine, who was discovered responsible of killing his spouse two years earlier after makes an attempt at hiring a hitman on the darkish internet fell by means of. Allwine is serving a sentence of life in jail, and continues to take care of that he was framed, casting doubt on laptop forensic proof discovered on 64 digital units taken from his dwelling.
On March 24, Allwine petitioned a Minnesota courtroom (PDF) to revisit his case, citing the accusations in opposition to Lanterman and his function as a key witness for the prosecution.
