The 2015 IRS hack stands as a stark reminder of the increasing sophistication and audacity of cybercriminals. This article delves into the intricate details of the breach, its impact on taxpayers, and the broader implications for cybersecurity.
The Initial Shock
The story begins with an individual named Michael Casper, who, like many others, was preparing to file his taxes. However, upon attempting to file, he received a jarring error message indicating that his tax return had already been filed. This marked the beginning of a complex ordeal that would eventually expose a massive security breach within the IRS.
•Casper's Experience: Upon contacting the IRS, Casper learned that his taxes had indeed been filed, and a deposit was being made to an unknown account. The IRS was unable to provide information about the account due to their own privacy laws.
•Casper's Investigation: Determined to uncover the truth, Casper utilized the IRS's "get transcript" website to obtain a copy of his tax return. However, he discovered that an account had already been created in his name.
•Form 4506: Casper then turned to Form 4506, through which he could request a copy of his tax receipts. After paying a fee and waiting several days, he finally obtained his tax receipt and discovered that almost $10,000 had been fraudulently claimed in his name and sent to a bank account at the First National Bank of Pennsylvania.
Unraveling the Crime
As Casper delved deeper, he uncovered a network of deceit and fraud that extended far beyond his own case.
•The Money Mule: Casper sought help from the Williamsport police department and traced the fraudulent account to a young woman studying at a Pennsylvania University. The woman claimed she had been hired for a job involving easy financial tasks, which required her to receive money, retrieve it, and send it to Nigeria via Western Union.
•Cybercrime Connection: The investigator realized that the young woman had been tricked into becoming a money mule, someone who receives money from cybercrime victims and then sends it to the criminals, allowing them to remain anonymous.
•IRS Notification: While Casper was investigating, the IRS was notified of a massive security breach.
The True Scope of the Breach
On May 26, 2015, the IRS announced that cybercriminals had stolen millions of dollars in tax returns and thousands of taxpayer documents.
•Data Acquisition: The criminals had been purchasing packages of American taxpayer data on the dark web, particularly from Turbo Tax users who had been hacked in 2014.
•Shadow Economy: A massive shadow economy exists where hackers sell stolen data, with a person's entire private information fetching around $100, credit card information about $15, and standalone tax information as little as $4.
•Profile Creation: The cybercriminals used the purchased data to create thousands of American taxpayer profiles, including names of family and pets, home addresses, and more.
•Get Transcript Exploit: They used these profiles to create accounts on the IRS's "get transcript" website to access tax receipts of numerous individuals. This explained why Casper was unable to create an account during his investigation.
•Fraudulent Returns: The criminals used the information from the "get transcript" website to submit thousands of fraudulent tax returns, resulting in over $50 million in payouts. This money was then sent to money mules, who transferred it to accounts in Africa, Eastern Europe, and China.
•Scale of the Breach: The breach affected over 700,000 people, with estimated damages far exceeding initial estimates.
International Links
The investigation revealed a connection to a Russian cybercrime group. This group used middleman scammers, primarily from Nigeria and Asia, to create Craigslist listings and send money from the money mules to hacker accounts in Eastern Europe.
The Aftermath
The aftermath of the 2015 IRS hack was disastrous for the agency and taxpayers.
•Criticism: The IRS faced severe criticism for its poor cybersecurity measures and lack of transparency.
•Financial Burden: The agency spent millions to improve its cybersecurity and provide free credit monitoring services to victims.
•Lawsuits: The IRS faced multiple lawsuits from taxpayers whose personal information had been stolen.
•Money Mule Consequences: The hack exposed the role of money mules in cybercrime, who often face serious legal consequences. Sentences for money mules can often be multiple years long.
Conclusion
The 2015 IRS hack serves as a critical lesson in the ongoing battle against cybercrime. The breach exposed vulnerabilities in government systems, highlighted the dangers of the dark web, and underscored the importance of cybersecurity awareness and preventative measures. The incident also shed light on the complex networks of cybercriminals and the devastating impact their activities can have on individuals and institutions.
